August 18th 20 am, the Tianjin Binhai New Area, the air Bureau of the building, here has been a temporary requisition for the coastal explosion rescue headquarters.

In a blue tent with flood control, Tianjin city in charge of safety and production of vice mayor He Shushan, Beijing military area command Shi Luze, Tianjin, and other relevant responsible person and some experts, such as sitting around the table, the table covered with a Tianjin port '12 - 8' explosion area image map of the big map.

That night, here is a rescue work conference. During the day of the survey results, confirm the previous command master Ruihai dangerous goods the quantity and distribution of, located at the core area of the explosion crater center, formerly placed in the 800 tons of ammonium nitrate and 500 tons of potassium nitrate is likely to is an important cause of the accident.

"China Times" reporter learned that the explosion of a new discovery of more than 300 tons of sodium metal, because it is flammable and explosive, it is likely to become a site of a time bomb, for the accident rescue and disposal to bring new problems.

800 tons of ammonium nitrate

"We want to fire again to save antichemical now." On the 18th, Tianjin port 8 - 12 "Ruihai, dangerous goods warehouse particularly serious fire explosion accident of the ten news conference, Tianjin municipal Party committee deputy secretary and mayor Huang Xingguo said" many of our comrades have never encountered such a complicated problem. "

At present, in addition to on-site rescue, another main task is the exploration of hazardous chemicals, mainly by the Beijing defense forces responsible for. 18, involved in the rescue of the Beijing Garrison chemical group sent a few teams, subregions on surrounding the accident investigation and on the investigation of the container were numbered -- No. 1 as empty containers, No. 2 is provided with the case of a non hazardous chemicals, No. 3 is box of hazardous chemicals. On the same day, participating in the investigation of the troops found that the core area of the accident there are two large container of metal sodium, which has a container site has cracked, metallic sodium scattered in the ground.

And he Shushan also at the press conference confirmed the presence of sodium metal scene, "the Ruihai logistics hazardous chemicals is a total of seven major types of approximately about 40 varieties, including oxides, flammable solids and cyanide, which flammable solid sodium metal and metal magnesium 500 tons and 700 tons of cyanide, oxides, including ammonium nitrate, potassium nitrate, other part is already blow up the."

As the cause of the accident has not been announced, the real explosion caused widespread speculation. Previously, a culprit mentioned in the media explosion accident may be made of metal sodium. However, the experts involved in the rescue of the accident does not think so, because the power of the metal is not so large, and there is still a lot of metal sodium. Presumably, the ammonium nitrate may be the real culprit.

Ministry of Public Security Fire Bureau Deputy Director Niu Yue in an interview with CCTV further confirmed that Ruihai company storage of goods, including about 800 tons of ammonium nitrate, potassium nitrate about 500 tons, dangerous chemicals a total of about 3000 tons.

It is understood that the main purpose of ammonium nitrate is fertilizer and explosives, while nitrate can also be configured with black powder, explosives and fireworks and other products. Qu Ruijing, a senior researcher at the chemical industry, told the China Times reporter, ammonium nitrate itself is a kind of explosive, powerful, in case of fire will produce a strong explosion.

At present, the core of the explosion area formed a huge puddle, nearly 10000 square meters. "China Times" from the headquarters to understand, according to Ruihai company provides storage of dangerous goods schematic diagram, the puddle zone is ammonium nitrate, potassium nitrate storage area, that is to say, the centre of the explosion just stored with 800 tons of ammonium nitrate and 500 tons of potassium nitrate, which may be a culprit in the huge explosion.

The man behind the accident

It is understood, Ruihai company "business" hazardous chemicals stored separately in the warehouse of the "box", "arrived in the library," storehouse "," hazardous chemical libraries "and" hazardous chemical libraries second ". But the stacking sequence of these regional hazardous chemicals is confusing. The "box" stacked dichloromethane, chloroform, tetrachloride titanium, formic acid, acetic acid, hydriodic acid, methyl sulfonic acid, calcium carbide, "arrived in Library stacking of ammonium nitrate, potassium nitrate, sodium cyanide, diphenyl amine, dimethyl aniline;" transit warehouse stacked hydrosulfide sodium, sodium sulfide, sodium hydroxide, maleic anhydride, hydroiodic acid; and two hazardous chemicals warehouse stacked potassium nitrate, sodium nitrate, calcium silicate, sodium sulfide, methyl sulfonic acid, cyano acetic acid, Dodecylbenzene sulfonic acid and other goods.

The chemical industry professionals said, this layout is obviously wrong Ruihai international. In accordance with the classification of hazardous chemicals, 4 categories and 5 kinds of dangerous chemicals can not be stacked together.

Similarly, the management of hazardous chemicals, the operator must undergo a rigorous training. However, Ruihai company stevedores foreign admits, the position of the workers had no after training of dangerous chemicals, qualification certificate has not been made. "China Times" reporter learned from an injured Ruihai employees, he posts the operation of protective measures only a top safety helmet.

In the view of Qu Ruijing, Ruihai company of dangerous chemical warehouse, in fact, is a similar to the transfer station yard, extensive management, many aspects are in violation of relevant regulations and standards. "The main problem is the amount of the standard. With sodium cyanide as an example, the maximum storage quantity should be only 10 tons, but in fact the Ruihai International stacked 700 tons. May not just the total amount, the number of individual packaging is also very likely to exceed, otherwise not due to pressure and the valve

 A cup of chocolate will not improve memory, but the taste buds on the tongue will not complain about this.


        There is a piece of chocolate, lovers can taste. Continuous drinking cocoa rich ingredient compound beverage three months later, during a memory test process, the performance of subjects 50 to 69 years of age and some younger than their twenties and thirties of the people's memory similar performance. But the problem is, if you want to get these benefits by eating chocolate, you need to eat a surprisingly large number of chocolate.


        This recent study shows that cocoa beans in a chemical called flavanols can produce beneficial effects on the brain. Flavanols are natural chemical substance that can be found in cocoa beans, blueberries, green tea keep in refrigerator and red wine being. Earlier studies found that the consumption of flavanol-rich diet mice showed enhanced memory, as well as some specific regions of the brain appear greater blood flow; New York City, Columbia University neurobiologist Scott Small wanted to know mechanism similar to the human brain may what impact.


       To get results, Small team found 19 volunteers aged between 50 to 69 years old, mixed with water and drink 900 ml of milk per day flavanol cocoa powder. These doses were asked twice daily drinking. While the remaining 18 volunteers were asked to drink one kind contains only 10 milligrams of cocoa flavanols powder drinks.


      During the three months before and after the experiment, two groups of volunteers underwent functional magnetic resonance imaging scans (fMRI). After three months of testing, the researchers compared the results after the scan found a higher blood flow to specific parts of drinking flavanol content of their subject hippocampus - the dentate gyrus of the flow rate higher than before the experiment 20%. the chocolate in 2~8 degree refrigerator will be more delicious At the same time, high consumption of flavanol content than subjects drinking the blood flow to the lower content of the subject matter of the dentate gyrus of the same flow rate is also showing growth. Interestingly, this region and memory loss caused by age are also relevant.

The beauty of natural hair is that it is porous, and it will easily accept hair coloring. But what about synthetic hair ? Synthetic hair is made of smooth plastic fibers which can not accept the coloring that human hair can. Whether it be because of illness or choice, some people that wear wigs choose wigs made with synthetic hair. Is there a way to change the hair color of these synthetic pieces, or does it need to forever remain the same color? While synthetic hair can not be lightened, there are ways to make the colors darker or richer.


Things You'll Need


-Fabric dye or

-Roux Fancifull Color Rinse (close to your current synthetic hair shade)

-Empty spray bottle


-Colored permanent markers (optional)


To dramatically change the color of synthetic hair, purchase a liquid fabric dye in your desired color. In one gallon of water, dissolve 4 oz. of dye. Submerge your hair piece in the dye and let it soak for at least 45 minutes. Continue this process until you have reached your desired shade. Rinse well and then take care to condition your hair piece as recommended by the manufacturer.


If you desire a softer change to your synthetic hair piece, a bottle of Roux Fancifull Hair Rinse is a great solution. To evenly distribute the coloring throughout the hair, pour it into a spray bottle. Spray the hair with the Fancifull, but do not rinse. Allow to dry. Re-spray if necessary.


If you desire fun, colorful stripes in your hair piece, use colored Sharpie markers or permanent ink to add the color stripe by stripe. Starting at the root, hold the marker so the wide side of the tip is against the hair shaft. Run along the hair until you have the result you want. This can be a long, slow process, so it is best to plan to do it when you have a lot of free sitting time.


Striped synthetic hair p ieces ]


Tips & Warnings


The lighter the original synthetic color, the easier it is to dye. If you wish to color your synthetic piece a bright color, starting with a platinum or blond wig is the best way to go. After coloring your piece, allow it to dry on something freestanding, such as a paper towel holder, so it touches nothing else and can dry evenly.

When coloring your hair piece, let it dry between dye baths before adding more dye as this will give you a more accurate idea of the actual resulting color.

Time is life,observed the renowned 20th-century writer, translator and educator Liang Shiqiu. It is most startling to hear a watch or clock clicking away the seconds, each click indicating the shortening of ones life little by little.For modern people, life is much like a battle against time. It seems that an invisible power urges us to do everything quicker, hastier, faster: more “快” (kuài, quick; fast; rapid; swift).




The character is commonly used to describe speed. The frequently used term for courieris 快递 (kuàidì) meaning express delivery;” 快餐 (kuàicān) is fast food;and 快车 (kuàichē) is an express train or bus. Meanwhile, 动作快 (dòngzuò kuài) is to act quicklyand 说话快 (shuōhuà kuài) means fast talking.Based on this, a quick worker is called 快手 (kuàishǒu), literally translated as fast hand”—its also the name of a popular live-streaming app (see feature). For example: Liu is such a quick and neat worker that he is known as Fast Hand Liu.However, when it comes to 快嘴 (kuàizuǐ, fast mouth), this isnt describing someones talking speed. Instead, it refers to people who voice their thoughts too readily, or have loose lipsin other words, a gossip.




You may also have heard people say 脑子快 (nǎozi kuài, the brain is fast). It means quick-witted, clever, and nimble.The term 眼疾手快 (yǎnjíshǒukuài, literally, quick of eye and deft of hand) is often used to describe fast reflexes.




If you want to express that you are doing something at top speed, you can turn to the idiom 快马加鞭 (kuàimǎ jiābiān, spurring on the fast horse). For example: 在这最后一个星期,我们要快马加鞭,按期完成任务。(Zài zhè zuìhòu yīgè xīngqí, wǒmen yào kuàimǎjiābiān, ànqí wánchéng rènwù. In the final week, we must spur on the fast horseand finish the project on time).




In some other cases, also indicates a future tense, meaning soonor before long.For example, you can say : 我快要五十岁了。(Wǒ kuàiyào wǔshí suìle. I am about to be 50.)




Another meaning of is sharp; keen.A sharp knife is 快刀 (kuàidāo). A Chinese saying states that “快刀斩乱麻” (kuàidāo zhǎn luànmá), which can be translated as cut a tangled skein of jute with a sharp knife.This old-fangled pearl of wisdom means that one should be resolute and take prompt measures in order to solve a complex problem.




But didnt always have these keen connotations. Its original meaning was pleased, happy, satisfied.As a pictophonetic characterwhere one component carries the meaning and another the soundits radical




, a simplified version of (xīn, heart), indicates that is an emotion-related word. Many two-character words containing have this meaning, such as 快乐 (kuàilè, happy), 快活 (Kuàihuo, jolly, merry, cheerful), or 快感 (kuàigǎn, apleasant sensation or delight). There is also the literary expression 快事 (kuàishì), meaning an occurrence that gives great satisfaction or pleasure.For instance, 他乡遇故知,实乃人生一大快事!(Tāxiāng yù gùzhī, shí nǎi rénshēng yī dà kuài shì! It is such a delight in life to encounter an old friend in a distant land!)




In this meaning, being served a sneak peak or trailer of a film is 先睹为快 (xiāndǔwéikuài, consider it a pleasure to be among the first to read or see); hurting oneself will lead to 亲痛仇快 (qīn tòng chóu kuài, sadden ones close friends and gladden ones enemies); when virtue is rewarded it 大快人心 (dàkuàirénxīn, gladdens the peoples hearts). The most interesting use of this exists in the word 快婿 (kuàixù). With 婿 (xù) meaning son-in-law, the word refers to an ideal match for ones daughter.




When the character is used to depict a personality, means straightforward, forthright, and plainspoken,as seen in words like 爽快 (shuǎngkuài, straightforward and outspoken).




Here we have the phrase 快人快语 (kuàirén kuàiyǔ), meaning straightforward talk from a straightforward person,which is usually used to flatter people face-to-face: “您快人快语!跟您聊天真是痛快” (Nín kuàirénkuàiyǔ! Gēn nín liáotiān zhēnshi tòngkuài! You are such a straightforward person, talking straightforwardly! Its such a pleasure to talk with you!)




Last but not least, sometimes is also a noun. In ancient times, a sheriff was called


捕快 (Bǔkuài), referring to a constable who caught criminals. But this word is no longer used for policemen in modern society. What do people call the cops now? Thats a lesson for another day.

Introduction to Emergency Generator Set


Hospitals, airports, shopping malls and office buildings, just to mention some examples, are very sensitive, in what concerns safety of people and goods, to power outages caused by faults in medium (MV) and low voltage (LV) distribution networks and even in high voltage (HV) transmission networks.


When a power outage occurs is necessary that communication systems, emergency lighting, smoke exhaust fans, fire fighting water pumping stations, security, lighting in buildings and other critical electrical systems and equipments, designated as essential loads (or critical), continue running.


To solve such problems common solution is the installation of LV diesel emergency generator sets, whose applications, characteristics and installation procedures must be in accordance with IEC Standard 60034.


Rated Power and Neutral Grounding of Emergency Generator


Rated power of LV diesel emergency generator sets depends on the operation regime: standby, prime and continuous, as defined in ISO Standard 8528.


In standby regime the available power supplied by the generator set varies with the value of the load during the lack of normal power supply and average power output is 70% of emergency standby power rating. Typical operation of this regime is 200 hours per year with a maximum of 500 hours per year.


In prime regime the available power supplied by the generator set varies with the value of the load for an unlimited period of time and average power output is 70% of prime power rating. Typical peak demand of 100% of prime-rated ekW with 10% of overload capability for emergency use for a maximum of 1 hour each 12 hours; overload functioning may not exceed 25 hours per year.


In continuous regime output is available without varying load for an unlimited time. Average power output is 70 100% of the continuous power rating. Typical peak demand is 100% of continuous rated ekW for 100% of operating hours.


According to the definitions stated above is easy to understand that the same generator set has different rated powers for each operation regime. Rated power in standby regime is higher than rated power in prime regime, which is higher than rated power in continuous regime.


Rated power of generator sets main be defined in kVA or kW for a cos Φ (Power Factor) = 0.8. It is also necessary to define the network frequency (50 Hz or 60 Hz).


In Table 1, as an example, are shown the values of rated power (kVA) of some generator sets of the same manufacturer and the same manufacturing series, according to the operation regime (f = 50 Hz).

In most mineral processing processes, flocculants are used for settling and centrifugation. CHINAFLOC - PAM series products used in mineral processing industry, could be selected according to the using conditions or produce  according to customer's specific requirements. The flocculants are optimized according to the types of mining, and our products and services are introduced in the field of beneficiation.


1.Once the coal is extracted, it is classified according to the grain size and then separated from the water according to the difference in the gravity of the coal and impurities in the medium of water. The coal floats on the top of water , the impurities sink to the bottom, and the processed coal is then sorted again to get the final product. In the process, a fine powder coal is produced, which requires further processing and recycling. This process is usually carried out by flotation methods, with flotation reagents to improve the separation efficiency of coal and impurities. Refined Coal is flotated , and the tail coal is setting down. The refined coal is recoveried through settled, filtered or centrifuged . The flocculant is applied in the settlement process to promote the separation of solid liquid. Then in the concentrator, water is recycled by the overflow of the concentrator. The powder coal is filtered and centrifuged. The efficiency of the separation process is improved by adding coagulant before adding the flocculant when we produce the  lignite or coal with high clayWe recommend our models of Chinafloc A2520 and Chinafloc N0510


2.In the process of gold and silver washing,the method of carbon slurry or carbon filter is generally adopted. Use activated carbon dissolved in cyanide to recover gold and silver. Before filtering, the ore is crushed and screened, and the selected minerals are added to the ball mill to add water and lime. Adding flocculant to each concentrator promotes the rapid deposition of solids and filters through a series of filters. So gold and silver have enough time to dissolve in cyanide. The gold and silver is extracted from the solution by a series of carbon adsorption slots, and in the negative direction of slurry , put the activated carbon in it and the gold and silver are sticked on the carbon particles  and be  extracted from the carbon particles. Most of the gold and silver have been extracted before the pulp reaches the last sink. Pouring the remaining pulp  into the sink, where the carbon particles arrive at the first sink, which has absorbed most of the gold and silver in the solution. The carbon particles with rich gold and silver are delivered to the washers, and gold and silver are flushed from the carbon particles with ultra-hot water. The solution containing gold and silver is collected through the electrolytic pool.we recommend our models of Chinafloc A2520 Chinafloc A2015


3.Lead and zinc processing.Lead and Zinc  are usually in the form of sulfide, sometimes also in the presence of oxides and silicates. For different forms of existence, the separation and processing of lead and zinc requires different techniques. In the separation process of sulfide lead and zinc: the mineral is oxidized to zinc oxide. The oxide is then leached with sulfuric acid. The PH of around 5 neutral filtrate and PH of 2.5 can make all the concentrate dissolved in sulfuric acid. Some company  added a heat filter enrichment process to furtherly  improve the recovery rate. Backflow settlement system is usually used for neutral concentrated overflow purification.we recommend our models of Chinafloc A3016 and Chinafloc A3018


4. Bauxite. First, the minerals are crushed to less than 1mm grade,and then  Add sodium hydroxide with  high temperature and high pressure. Aluminum is dissolved in highly corrosive liquids, and other impurities of soluble aluminate are not dissolved. The gravel   along with the primary concentrated mineral slurry are removed after the process. Flocculants are added to the primary concentration pool. This is a very important process of technology to get clear overflow. The bottom flow of the concentration pool , that is  the red mud will be processed by a reverse flow settlement process. In this process the aluminum in the liquid is recycled through a series of sink sinks. The flocculant is then used again to facilitate rapid settlement and to obtain the required clarifying overflow.the overflow of  primary concentration with  aluminum is filtered ,after cooling (48 hours), and the hydrate of aluminum to facilitate the precipitation of the aluminum trihydrate. And the get  aluminum after filtered ,washing and calcined..we recommend our models of ChinaflocCF7660 Chinafloc-CF7823 and Chinafloc-CF7950


5.Copper. The mineral can be separated from waste materials or pulsates through crushing g, and the mineral is crushed again, then be pulverized again with a ball mill or agitator. The ultimate mineral particle size is usually less than 100um. In the final crushing process, add the collector to the pulp. The collector can absorb copper sulphide and make its particles hydrophobic. The copper mines will be recycled through flotation processes. In flotation the air will be passed into the pulp. The foaming agent will also be added to produce bubbles and make the copper particles firmly attached to the bubbles at the top of the pulp. The slurry or tailings from the flotation pool will be into the enrichment pool for further settlement. At this time,The flocculant is added to facilitate rapid settlement and produce  overflow. Clarification of overflow will be used as circulation water. The remaining concentrated tailings will be centrifuged dewatering, and the flocculant will be added as a centrifugal additive. The bubbles (concentrates) which  with copper  are separated from the overflow  by  mechanical method. Then it is concentrated and dehydrated. The flocculant is used to improve the efficiency of settlement and filtration. The final refined mining  or filter cake contains nearly 25 to 35 percent copper. This will be recycled through high temperature metallurgy.we recommend our models of Chinafloc A3016 and Chinafloc A3016A


6. Phosphate.the main dressing method basically has the following ways: direct flotation and reverse flotation, anti - positive (positive - DE) scrubbing flotation, double reverse flotation, desliming, roasting digestion process, chemical processing, heavy medium separation and so on. During the  process of Phosphate production, it will  produce a large number of slime, waste rock, waste water, etc.,and the the water and the soilnear the mining  will be polluted , it will make the t ecological balance destruction if there is without  appropriate measures.and it will  affect local production and living. The waste water in the phosphate industry mainly comes from external drainage of mine and outdoor quarry, mineral processing wastewater, machine repair and auto repair water, life water, etc. Our company may take different measures according to the  water source  and quality  to meet the emission standards. In the process of wastewater treatment, various kinds of polymers can be used in the process of chemical production. These polymers can be used to speed up wastewater treatment and improve recycling efficiency of wastewater. T he flocculant can make the fine particles more compact during the sludge dewateringt process, Chinafloc pam can greatly reduce the dosage of the flocculating agent, tail mud rapid subsidence, dehydration, and effectively make the tail mud solid content over 60%, it is conveninent  to carry the tailing sludge to quarry for mine filling, vegetation, farming, planting, improve the land utilization.we recommend our models of Chinafloc A2520 and Chinafloc A3016


Chinafloc can supply various of flocculant for different mineral processing to meet different requirement from different clients.Chinafloc will continuly provide  more valuable  products and services for you.
