Aluminum silicate is a silicate, its chemical formula is Al2SiO5, because most of the silicate structure is very complex, often written in salt form but in the form of a metal oxide, the aluminum silicate is often Al2O3 SiO2 writing. Aluminum silicate density of 2.8 to 2.9 g / cm3, the refractive index is 1.56, the hardness and the ore type, water content, changes between 4.5 to 7.5. Aluminum silicate powder is often used as a fireproof material, for example in glass industry as a glass kiln.

General application
1 filler for glass, pottery, pigment and paint;
2 is an ideal substitute for titanium dioxide and high-quality kaolin in paints, and pigments are widely used in paint, leather, printing and dyeing, ink, paper, plastics, rubber and other aspects;
3 used to make high temperature fire resistant sound insulation cotton, board, tube, seam felt, fire insulation cloth, high temperature resistant paper, refractory insulation rope, belt, fire insulation needle blanket (with silk, blow), brick, inorganic fire decorative board. Inorganic fireproof rolling curtain, etc.;
4 as filler adhesive and sealant, can improve the hardness, whiteness, wear resistance, weather resistance, storage stability.
Used for paint
1, ultra-fine aluminum silicate replace part of titanium dioxide, dry film covering power won't change, and can improve the whiteness of paint. If the amount of titanium dioxide, obviously improve the dry film covering power, greatly improve whiteness.
2, ultra-fine aluminum silicate pH range of 9.7-10.8, which has a pH buffer. Especially in the vinyl acetate emulsion paint storage process can prevent the hydrolysis of acetic acid due to the pH value of the phenomenon, increased the emulsion paint dispersion stability, while avoiding the metal container corrosion.
3, super fine aluminum silicate grid structure, make the latex paint system slightly thickening, has the very good suspension property, and prevent sink of solids and surface water.
4, ultra-fine aluminum silicate emulsion film has a good scrub resistance, weather resistance, in addition to shorten the table dry time.
5, superfine aluminum silicate has extinction effect, so in half light, no light paint can be used as an economic matting agent, in bright paint should not use.
