Or it is a variety of, when selection is a variety of is used as arc protection powder, it can mutually cooperate with, play the role of common arc protection and fire-retardant, three's machine
Reason is as follows respectively:
When arc burning glove surface, the humidity on local material surface is significantly improved, and modified aluminium hydroxide is being heated to
220 DEG C or so can decomposite rapidly the crystallization water and absorb a large amount of heat, to reduce the temperature of material surface.Aluminium hydroxide
The free carbon that the crystallization water decomposited generates when can decompose with latex under the catalytic action of aluminum oxide reacts, and produces
The carbon monoxide and carbon dioxide of volatilization prevent the formation in conductive charing channel.

The influence and extraneous destruction of condition, to extend storage period.It is red when microcapsule coated red phosphorus temperature reaches 400 DEG C -450 DEG C
Phosphorus depolymerization forms white phosphorus, and white phosphorus can be quickly oxidized to have sticking oxyacid in the presence of aqueous vapor, and this kind of acid is in covering base
While material surface, and dehydration carbonization can be accelerated on the surface of the material, the liquid film and layer of charcoal of formation then can be by external oxygen, volatility
Combustible and heat and the substrate of inside separate, to allow flameout.
The arc protection and fire retardant mechanism of microcapsule-coated ammonium polyphosphate are broadly divided into condensed phase and gas-phase mechanism.Agglomerate camera
