  • Do FR-V6 flame retardant standard env...

    [2016-07-02]

    Today, plastic, rubber, chemical fiber, paint and other polymer materials are increasingly filled with people's lives. Polymer materials to bring light, efficient and other advantages, but also for people's lives buried safety risks. Long carbon chain of polymer materials in the heat will be broken down into small molecules flammable, easily lead to fire. How to avoid the safety risks, so that the polymer material to better serve people's daily life? This requires the addition of FR-V6 flame retardants to the material according to the relevant standards. The main role of FR-V6 flame retardants is to slow down the time when the polymer burns or decomposes, extending people's escape time in a fire. Proper use of flame retardants can be described as significant, but some enterprises in the production and construction process, for cost and other reasons, not in accordance with the standard to add flame retardants, and even simply do not use flame retardants, and ultimately lead to disaster. In 2009, CCTV new building was splashed fireworks ignition, the fire instantly spread, a full 6 hours of burning, resulting in direct economic losses of 163.83 million yuan. The survey results show that this fire is due to flame retardant material selection due to substandard. The building curtain wall construction side should use flame retardant grade B1 (flame retardant) extruded polystyrene insulation board, but the purchase of the combustion is not up to B2 (combustible) extruded board. Coincidentally, 2010 Shanghai Jing'an District teacher apartment fire is also because the wall insulation layer is not required to choose a flame retardant properties of the material, but illegal use of a large number of polyurethane foam and other highly explosive materials, and ultimately lead to 58 people were killed in the disaster. Two fires exposed the lack of fire control in China. It is understood that China's fire-retardant legislation is still in its infancy, the standard imperfect and safety supervision measures are not so that different industries are facing fire hazards. China Fire-retardant Society Secretary-General Zhou Zhengmao pointed out that China should speed up the revision of the relevant fire-retardant products and the establishment of third-party testing organizations to further improve the relevant laws and regulations, strengthen supervision, so that flame retardant materials play a fire retardant role. It is reported that in 2015, Shenzhen Airlines occurred arson case, it is precisely because the aircraft seat in strict accordance with the standard fire-retardant manufacturing, and ultimately to avoid a tragedy. Afterwards, an airline captain Zhang Peng said in an interview with reporters, the aircraft floor, seats, doors, are made of high flame-retardant properties of the material, will not be easily ignited, the possibility of fire is not ; Even if the local fire, can also be used in the cabin fire extinguisher in time to extinguish. In addition to standards and regulatory issues, the flame retardant industry is also facing a major controversy in environmental protection: halogen or halogen-free? After hexabromocyclododecane is defined as persistent organic pollutants are banned, many unknown people believe that halogen-containing flame retardants are irreversible pollution and toxicity to the environment and the human body. Many environmental groups also hold high the banner of halogen-free, requiring bromine products permanently quit the "rivers and lakes." The halogen-free movement has shrunk the market for brominated flame retardants. An industry source told reporters that in 2004 halogen-free flame retardant aluminum hydroxide production is 2,000 tons, and by 2015, production has soared to 100,000 tons. "Preemption is of course the market for brominated flame retardants."

    [2016-07-02]

    Just like any other industry, the development trend of flame retardant manufacturers are also diversified, green, high performance technology. Currently most common flame retardants into the market for aluminum hydroxide, magnesium hydroxide as a representative of inorganic flame retardants, brominated, and as the representative of the organic phosphorus flame retardants flame retardants. Data show that 2013 ATH over brominated flame retardants to become the world's largest amount of flame retardant, flame retardant 33% of the total amount. Aluminum hydroxide as a representative of inorganic flame retardant thermal decomposition at high temperatures, absorb a lot of heat to reduce the surface temperature of the polymer; some flame retardants can also decompose water vapor, absorb large amounts of latent heat, reducing the synthesis of materials in flame surface temperature and dilute polymer surface concentration of the flammable gas. This type of inorganic flame retardant and good stability, not evaporation, precipitation, low toxicity and does not cost advantages. But in content, dispersion, polymer processing and mechanical properties of, there is still room to improve. Industry experts believe that inorganic flame retardants will be the future development of Super fine and high affinity, and improve its synergies. Such as the development of smaller particle size of inorganic flame retardant, reducing wear and tear on equipment. Surface modification agent such as through the development of efficient, enhancing the compatibility of inorganic flame retardant and body material, reduce the impact on processing and mechanical properties. Flame retardant effect of aluminum hydroxide, modification can be functional, utilizing the synergistic effect to improve flame retardancy. Bromine, phosphorus, organic flame retardant, high polymer will be the main direction of these products in the future. Han Songqing told reporters that the compounds being absorbed by the body will first on the human body and adversely affect the ecology and polymers of molecular weight greater than 1000 to absorbed by the digestive tract, and thus cannot be through participation in the metabolism of the damage on the human body. EU REACH regulations and United States were given to the toxic substances Control Act of macromolecular aggregates-type flame retardant agent "exemptions", listing it as no registration is required to use the substance. In addition, the intumescent flame retardant and flame-retarding industry focused research areas. It is understood that currently realize industrialization of intumescent flame retardant is not much. This system formed by acid source, carbon source, and the source, in heating or burning process, sources of acid esterification reaction with the carbon source, so that the latter dehydrate form a porous layer of Coke. The carbon layer able to isolate heat transfer, prevents oxygen from entering the combustion area and inhibit the release of flammable products. In air when heated to decomposition processes can release a large amount of toxic and flammable gas compounds can dilute material during combustion gases. It is understood that catalyzed into carbon and its multifunctional composite flame retardant is development of intumescent flame retardant. This technique by adding metal oxides, silicon and boron compounds have synergistic effects of additives such as, improving previous addition of intumescent flame retardant, char unstable defects, increase the amount of charring, improve the quality of carbon layer, ultimately retarding effect increased significantly. In recent years, the flame retardant industry has a revolutionary technique. The Chinese Academy of engineering academician, Professor at Sichuan University syntheses team developed a without adding nitrogen, phosphorus, bromine flame retardant elements such as the char formation flame retardant copolyester. At high temperatures, with a specific structure and does not contain monomers can promote the modification of polyester flame retardant elements, making it a large number of char, so as to achieve a good effect. And because they do not contain flame retardant elements, units in the process of flame retardant cross-linked and non-metal, the complete elimination of the traditional polyester flame retardant systems in the inevitable problem of metal. In addition, the design and synthesis of copolyesters containing only carbon, hydrogen, oxygen, three basic elements, will not have any adverse impact on humans and the environment. The technique in flame-retarding industry of high concern, industry experts have said that this only through the design of structures and changes, rather than adding flame retardant elements, you can achieve the purpose fire retardant technology revolutionized the system guidelines.

    United Kingdom Ou Gong cast back is near at hand, despite recent polls showing liuoupai regained the upper hand, but if the result of the referendum is won back Europe, what would happen then? United Kingdom will smooth the process of withdrawal from the EU? Polyurethane rigid foam flame retardant will be affected? In theory, if the United Kingdom public referendum result is returned-Europe, seems fairly simple exit after Credit Suisse are summarized as follows: United Kingdom preliminary consultations with the EU, followed by United Kingdom Prime Minister to the President of the European Council sent a letter to express United Kingdom want EU Treaty 50th article to discuss idea of withdrawal from the EU. Two years later, the United Kingdom will automatically leave the EU, unless the other 27 countries of the European Union unanimously agreed to extend the talks. If this is the case, then negotiations will continue up to the end, then United Kingdom out of the EU. Specific procedures are as follows: However, the fact is not so simple. Credit Suisse said that after the referendum is over the potential for political and economic turmoil will trigger a series of events that will disrupt the process. Credit Suisse believes that there are two major factors that increase the complexity of Europe back: First If the result is SW back slightly ahead of the referendum, then the United Kingdom Government at the Executive retreat-Europe programme, will be resisted by Parliament, especially if Europe leads United Kingdom cannot easily enter the EU's single market. Second In the course of negotiations after the vote, if the United Kingdom's ties with the EU appears uncertain, United Kingdom into recession, it will lead to United Kingdom public support again in Europe. Credit Suisse said that if Europeans are ahead in a referendum following a massive economic turmoil does not appear, then the process of withdrawal from the EU will be relatively smooth. However, if European victory, or United Kingdom economic recession lead to reverse public opinion, might deter the United Kingdom eventually in the European Union. This complex process is as follows: Process flow. PNG also said Credit Suisse, drawn from the above rough estimates, if the United Kingdom referendum results are out, so the possibility of eventual successful exit for 70%.

    Flame retardant requirements increase with economic development, and environmental appeals of non-halogen flame retardant used by more and more attention. Many types of halogen-free flame retardants, including inorganic, organic silicon, p-n intumescent and Nano. These good flame retardance of flame retardant, low prices, and smoke, toxic, environmental protection. Dosage, and issues affecting the mechanical properties of materials, in the following ways: Super fine, micro-capsule technology with other organic and inorganic flame retardant compound, creating synergies; Development of new environment-friendly flame retardant material. Halogen-free flame retardants is currently the world's largest production of flame retardants, brominated flame retardants. Less chlorine series flame retardants varieties to industrial production, mainly for chlorinated paraffin, cloning, Hite acids and their anhydrides, rigid polyurethane foam used in chlorine-containing flame retardants for three 2-(isopropyl chloride) phosphate (TCPP), TRIS-chloroethyl phosphate (TCEP). Halogen-free flame retardant flame retardant effect, market demand, but generated when burning large amounts of halogen flame retardants on human and environmentally hazardous smoke and corrosive gases, and toxic gases. With the enhancement of environmental awareness around the world, States promulgated laws gradually restricting and prohibiting the use of halogen-free flame retardant agent, therefore, from the perspective of long-term development, is halogen-free flame retardant flame retardant development direction in the future.
