As a stabilizer, suspension agent, thickening agent used in personal care (such as toothpaste), cosmetics, medicine, pesticides, polish, lubricants, coatings, paints, lithium batteries, engineering plastics and other fields. The product is white in small flake or powder shape, the most fine granularity up to -325 mesh. Tasteless and odorless. General drying weight loss can be controlled below 7.5%, burning weight loss below 15%. In water can be expanded into colloidal dispersion, slightly basic, colloidal stable pH3.5 ~ 11, the usual dosage is 0.5% ~ 2.5%, the highest dosage is 5%. The viscosity of 5% water dispersion ranges from 50 to 700CPS, and some can reach thousands of CPS.
Magnesium aluminum silicate (disintegrating agent), with a unique three-dimensional space chain structure and special needle and rod crystal structure, thus has unusual colloid and adsorption properties. Its excellent thickening, suspension, colloidal shaking and melting properties are widely used in the paint industry. The association network structure of "card palace" is formed in the water medium.
