pom 1966 ~ 2002 china pom production capacity of the average annual growth rate of 16.7%, an average annual growth rate of 18.8%, visible pom manufacturers to expand domestic
production capacity is imperative. china pom manufacturer is expected in 2005 will reach 6, the total production capacity will reach 130 thousand tons / year; (not remove) is expected in 2010 china pom production capacity of 190 thousand tons / year, pom from 2005 to 2010, the production capacity of the average annual growth rate will reach 7.9%. pom pom china caused productivity growth can not meet the demand. abs qu-0191s↖
pc, the residual bisphenol a, the higher the temperature, the faster speed of release. therefore, should not be "pc water bottle filled with hot water. if your kettle number is 07, the following methods can reduce the risk: do not heat when using, do not direct in the sun. don’t use a dishwasher&a bowl machine to clean the kettle. di before use, rinse with baking soda&warm water&dry naturally at room temperature. if the container has any
falls/breakage, it is recommended not to use it because the surface of the plastic is prone to contain bacteria if there are fine pits. avoid repeated use of aged plastic appliances. a cup of low is 7 cups are made of polycarbonate used, i.e., pc, used to call a bisphenol a material in the production process of raw materials in "pc, pc" in the material will be more/less exist bisphenol a monomer, the higher the temperature, the faster speed of release. pc "pc" -1750, pc "pc" -1100, pc "pc" -1150, pc "pc" -1220, pc "pc" -1070, pc "pc" -1070u, pc "pc" 3025ir, 3022, pc / / pc / / -1220u.
the chemical&physical properties of pa6 are similar to those of pa66, however, it has a lower melting point&a wide range of process temperatures. its impact resistance&solubility are better than pa66, but its moisture absorption is stronger. because many of the quality characteristics of plastic parts are subject to moisture absorption, so the use of pa6 design products should take full account of this. in order to improve the mechanical properties of pa6, a variety of modifiers are often added.
