More and more engineering plastics are gradually replacing metal, glass and ceramics in automobiles, airplanes, electronics and other industries. For materials exposed to high temperatures, their flame retardancy has become increasingly important.
With the continuous advancement of polymer synthesis and processing technology, engineering plastics have penetrated into various fields of production and life. In many applications, the flame retardancy of plastics is an important performance indicator for the application of materials, and some plastic additives, such as halogen-containing flame retardants, may have potential hazards to the environment and human health due to {TodayHot}. Therefore, in order to solve this contradiction, some users of engineering plastics have abandoned the application of these plastic additives and switched to engineering plastics that have flame retardant properties themselves.
Flame retardant polymers generally also have other excellent properties such as strength, dimensional stability, chemical resistance and abrasion resistance, etc., but these materials are generally more expensive than those that do not have flame retardancy, however These resins are needed to be used in applications where high performance and high flame retardancy are required. These polymers mainly include: polyetheretherketone (PEEK), polyetherimide (PEI), polyphenylene sulfide (PPS), polyphenylsulfone (PPSU), polyethersulfone (PES), polyvinylidene fluoride ( PVDF) and liquid crystal polymer (LCP). Other polymers such as PVC, modified polyphenylene ether (PPO), etc. have some flame retardancy, but require a certain amount of additives to enhance this performance.
Refinement of Copper removing agent and Decoppering Agent through Lead Fire Process
Copper removing agent, lead copper removing agent, lead fire smelting copper removing agent, lead refining copper removing agent, lead copper removing agent for export, crude lead fire smelting copper removing agent, No. 2 lead refining copper removing agent
Bismuth is the impurity which is the most difficult to remove during fire refining of crude lead. lead fire process refined debismuthizing agent is prepared and produced by Luanchuan Hengkai Metallurgical Materials Sales Co., Ltd after research and development for many years. The lead fire smelting novel copper removing agent is prepared and produced by our company. After the copper removing agent produced by our company is used, the copper content in the lead after copper removal is within 0.0002. More importantly, after the copper removing agent produced by our company is used, no pollution is produced (no smoke), the emission of sulfur dioxide is reduced, there is no low-altitude pollution, the operation is simple for workers, the operating environment is improved, and free technical guidance is given for the first-time use.
"Hengkai Metallurgical" brand patent products (patent number: 201808178848) is environmental protection copper removing agent 1#. Environmental protection formula copper removing agent 2# belongs to upgrade products of the copper removing agent 1#. After the copper removing agent produced by our company is used, the copper content in the lead is less than 0.00015 after copper removal. The product is characterized by small usage, no pungent smell, no low-altitude pollution, easier operation and low slag rate. Product advantages: the content of existing copper removing agent in the market is 6%-10%, which is lower than ours. Currently, the company is the only one in China that has passed EIA acceptance. The company adopts the most advanced independently-developed automatic production line to produce copper removing agent. The annual output is 15,000 tons, and the moisture content is less than 0.01%.
Luanchuan Hengkai Metallurgical Materials Sales Co., Ltd. is a domestic professional R & D and production manufacturer engaged in lead smelting copper removing agent and lead-refined debismuthizing agent. The company cooperates with a number of scientific research institutions, and it has abundant strength in independent research and development, design automation assembly line operation, production and examination, which has formed the production capacity of 30,000 tons in copper removing agent, debismuthizing agent, iron sulphide, Ferro sulphur, alloy sand, ferrous sulphide, Pyrite and other series products. It is one of the domestic production enterprises with the largest scale. The company passed the ISO9001 international quality system certification in April 2018. The patented products (patent No.: 201808178848) "Hengkai Metallurgical" brand copper removing agent and ferro sulphur gain consistent praise from clients after innovation, research and development and improvement by the clients for many years due to high product quality and cheap price.
