MC nylon is a new type of engineering plastic, which is made of caprolactam as the main raw material by anion polymerization under atmospheric pressure. MC nylon is gradually replacing copper, aluminum, steel and other metal materials and is widely used in textile, rubber, [...]
1.. Impregnation method
A certain amount of zrocl2.8h20 was dissolved in an appropriate amount of deionized water, and ammonia was added to form a hydrogel. The pH value was adjusted to 9.0. After being placed at room temperature for 12h, the precipitate was filtered and [...]
China’s plastic flame retardant material is mainly based on decabromodiphenyl ether, but decabromodiphenyl ether in combustion will produce toxic carcinogenic polybrominated dibenzofuran and other substances, and make it some countries to resist the use of. Therefore, flame-retardant materials also develop towards the direction of [...]
