Product introduction:
Aluminum hydroxide, also known as hydrated alumina, a halogen-free environmentally friendly flame retardant. It can not only flame retardant, can smoke suppression and does not produce soluble drop and toxic gases and the price is cheaper than that of halogen, phosphorus and other system is inorganic flame retardants used most widely. The company produced aluminum hydroxide flame retardant agent with superfine, high purity, white, particle size distribution uniform characteristics; the after advanced surface treatment technology, and polymer compatibility, add a large number of can greatly reduce the impact on the physical and mechanical properties of materials,.
Flame retarding mechanism
When the flame retardant agent when heated to a certain degree to dehydration absorption heat and vaporizing H2O so as to reduce the concentration of combustible temperature and dilute combustible matter vaporization and combustion supporting gas, also in combustible surface formation isolation oxide layer, in order to achieve fuel flame retardant objective.

Toxicity:The toxicity of aluminum mainly includes two aspects: the first is the mechanical stimulation to lung tissue; the second is to make protein precipitation and form fiber-like irreversible protein compounds with non-inflammatory performance. The inhalation of aluminum dust can damage the lungs to cause bauxite lung, the chronic symptoms of which have weight loss, easy fatigue, difficult breathing and cough. Aluminum hydroxide is more likely to cause alveolar epithelial hyperplasia than aluminum.The maximum allowable concentration of aluminum hydroxide is 6 mg/m3.Small trauma can be first treated with alcohol and gasoline, and then covered with non-toxic dressing; large wound can be excised and sutured, and then treated with sulfonamides and penicillin therapy. People working in dusty places should wear gas masks, protective glasses and dust protective overalls to protect the skin and eyes. In addition, every year people should attend a regular physical examination.
