Introduction:
Aluminum hydroxide Introduction:
Aluminum hydroxide is a kind of inorganic substance, chemical formula Al(OH)3, is the hydroxide of aluminum. Aluminum hydroxide can react with both acid to form salt and water and strong base to form salt and water, so it is a amphoteric hydroxide. It is also called alumic acid (H3AlO3) because of its acidity. But the actual reaction with the base produces tetrahydroxy aluminate ([Al(OH)4]-).
Aluminum hydroxide Usage:
Aluminum hydroxide flame retardant, not only has the function of non-toxic, good stability, does not produce toxic gases at high temperature, but also reduce the advantages of plastic burning smoke emission, and low temperature endothermic dehydration, at about 235-350℃. Aluminum hydroxide flame retardant polyolefin can be used as building materials and interior decoration materials of automobile, ship, etc.
It is widely used in artificial marble, wire and cable, resin, rubber, plastic and other environmentally friendly flame retardant.
The special aluminum hydroxide sintering production process, low iron content of aluminum hydroxide, high whiteness, can be used to produce solid surface materials (artificial marble) polyester resin or acrylic resin with the filler, the basic raw material of toothpaste. Widely used in artificial marble, DuPont, rubber, plastic, resin crafts, etc.
Low iron content agate grade aluminum hydroxide, high whiteness, it is good material to produce solid surface materials (artificial marble) with polyester resin filler, toothpaste, artificial agate raw materials etc. The artificial agate made from this kind of ATH will be in good brightness and smooth surface, good abrasion resistance, stain resistance, impact resistance, high structural strength, is good filler in ideal modern new building materials and technology.
This product is low sodium content in ferrosilicon powder, can improve the optical properties of glass, reduce the swelling rate, whiteness, transparency, gloss, brightness enhancement of thermal shock resistance and chemical corrosion resistance can increase the glass.
Micron aluminum hydroxide property is to flame retardant self extinguishing, thus adding advanced composite materials in the plastic and rubber products, it will not only have the function of flame retardant and smoke suppression effect, but also anti leakage resistance, abrasion resistance enhancement.
