Description

Technical Field

[0001] The invention relates to the technical field of material mixing processing, in particular to a high-efficiency multi-stage material mixing device for ABS resin drying processing. Background Art

[0002] ABS resin is the polymer with the largest output and the most extensive application. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigidity. ABS engineering plastics have excellent comprehensive properties, excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, and good molding and machining. ABS resin is resistant to water, inorganic salts, alkalis and acids, insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons. ABS resin maintains the excellent electrical properties and easy processing and molding of styrene, and increases elasticity, strength (characteristics of butadiene), heat resistance and corrosion resistance (excellent properties of acrylonitrile), and has high surface hardness and good chemical resistance. ABS engineering plastics have a wide range of uses, mainly in industries such as machinery, electrical, textile, automobile and shipbuilding. The performance of ABS is between general-purpose plastics and engineering plastics. It has good impact resistance, is basically not notch-sensitive, has excellent fluidity, and is relatively cheap.
