Description

Technical Field

[0002] Polyethylene wax, also known as PE wax, is a white or light yellow solid with excellent cold resistance, heat resistance, chemical resistance and wear resistance. It is mainly prepared through the ethylene polymerization process, with a relative molecular mass of about 1000-4000 and a melting point of about 95°C. Polyethylene wax is non-toxic and non-corrosive, has high hardness, softening point, low melt viscosity, and is widely used in the plastics industry. This material can be used as a lubricant, dispersant, slip agent, resin additive and release agent, which can improve the gloss and processing performance of the product, improve fluidity and demoulding properties, and has good electrical properties and dispersibility.

[0003] The spray granulation process is required in the process of polyethylene wax powder making. The particles with smaller size are also called powder. The slurry sent into the granulation tower is formed into mist under the action of the atomizing injector, and then naturally dried and formed into particles / powder under contact with hot air. However, the current polyethylene wax atomizing granulator still has some shortcomings. For example, when the micro-particles are powdered, there are uneven heat fusion and uneven drying inside, which affects the specifications and quality of the subsequent finished products.
