Production method of ultrafine aluminum hydroxide powder
The production of ultrafine aluminum hydroxide micropowder is divided into two categories: mechanical method and chemical method. Chemical methods include sodium aluminate solution seed decomposition method, metal alcohol salt method, microemulsion method, hypergravity method and water thermocouple method, etc.
Effects of aging time and aging temperature on particle size of aluminum hydroxide
As a common catalyst carrier, alumina has a very complex system with various morphologies. It is the same crystal phase, and its pore structure, physicochemical properties and catalytic performance are also different. The characteristics of alumina depend on the purity, dispersion, crystallinity, etc. of the precursor.
Aluminum hydroxide flame retardant selection should pay attention to quality indicators
Aluminum hydroxide flame retardant has the advantages of non-toxicity, good stability, no toxic gas at high temperature, and can also reduce the amount of smoke during plastic combustion, and the dehydration and heat absorption temperature is low. Flame retardant polyolefins with 60% aluminum hydroxide added can be used as building materials, interior decoration materials for automobiles and ships.
