Description

Technical Field

[0001] The invention relates to the field of polyethylene wax drying equipment, in particular to a polyethylene wax drying device and a drying method thereof. Background Art

[0002] Polyethylene wax (PE wax), also known as polymer wax or polyethylene wax for short, is widely used due to its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this wax can be directly added to polyolefin processing as an additive, which can increase the gloss and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene and ABS and the demoulding properties of polymethyl methacrylate and polycarbonate. Compared with PVC and other external lubricants, polyethylene wax has a stronger internal lubrication effect.

[0003] Polyethylene wax needs to be dried during processing to reduce its water content. However, the existing drying equipment cannot smooth the polyethylene wax during use, resulting in inconsistent water content inside the polyethylene wax after drying, which affects the product quality of the polyethylene wax. At the same time, the drying is carried out by a hot air blower. When the polyethylene wax inside the drying equipment is dried, the hot air passes through the outside of the polyethylene wax and then scatters in the air, causing heat waste.
