Abstract

The present invention discloses a thermoplastic resin granulation method and a device thereof. The method comprises the following steps: carrying out composite extruding on a thermoplastic resin and an inorganic filler with an extruder to form a composite resin; carrying out bracing water cooling and granulation on the composite resin with a bracing granulation machine to form particles; screening the particles with a screening machine; and separating the particles from the powder with a particle separation device. According to the thermoplastic resin granulation method of the present invention, bracing water cooling, granulation and screening are sequentially performed, and then the particle separation device is adopted to separate the particles from the powder, such that the powder content in the particles is reduced, the powder problem of the downstream injection molding plant during the production process is effectively solved, and the production efficiency and the yield are improved.

Description

technical field

[0001] The invention relates to the technical field of chemical industry, in particular to a thermoplastic resin granulation method and equipment. Background technique

[0002] Thermoplastic resin (Thermoplastic), because it can be transformed into a solid state and a liquid state under changing temperature conditions, has the advantages of strong processability, compound modification and strong operability, and is widely used in electronics, automobiles, and machinery manufacturing. , daily necessities and other fields.

[0003] Thermoplastic resins are mostly used in the field of engineering plastics in the form of composite materials added with glass fiber or inorganic fillers, and in order to enhance strength and reduce costs, the production process of thermoplastic resins is mostly low-cost composite extrusion strand cold-cut granulation model. However, in the cold-cut granulation process of extruded strands, a large amount of powder will be produced d...
