Usage:
1. Used as a water-based drilling fluids, and thickening agent and fitrate reduceer of completion fluids, thickening agent has obvious effect on brine drilling fluid. Also can be used for filtrate reducer of oil well cement. Cross-linking with the polyvalent metal ions into a gel.
2. It is used for cracking method to extract polymerized dispersing agents such as oil water base gel fracturing fluid, polystyrene and polyvinyl chloride. Also for latex thickening agent in painit industry, hygristor in electronics industry, cement anti-coagulant agent and water retention agent in construction industry. Glazing in ceramic industry and toothpaste binder. Also widely used in many aispects such as printing anid dyeing, textile, paper, pharmaceutical, health, food, cigarettes, pesticides and fire extinguishing agent..
3. As surfactants, protective colloids, emulsion stabilizers in combination with emulsion such as vinyl chloride, vinyl acetate emulsion, and a tackifier, dispersant, dispersion stabilizer of emulsion. Widely used in many aspects such as coatings, fibers,dyeing, paper,cosmetics,pharmaceuticals,pesticides. There are many uses in oil exploitatioon and machinery industry.
