The main use is as a dispersant in the production of polyvinyl chloride, and it is the main auxiliary agent for the preparation of PVC by suspension polymerization. In addition, it is used as thickener, stabilizer, emulsifier, excipient, water-retaining agent in the production of other petrochemicals, coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. , film formers, etc. The application of synthetic resin can make the obtained product have the characteristics of regular particle size, looseness, suitable specific gravity, and excellent processing performance, which basically replaces gelatin and polyvinyl alcohol as dispersant. In addition, in the construction process of the construction industry, it is mainly used in mechanized construction such as wall building, stucco decoration, and caulking; especially in decorative construction, it is used to paste tiles, marble, and plastic decoration. amount of cement. Used as a thickener in the coating industry, it can make the layer bright and delicate, not powder, and improve the leveling performance.
