Application of Microwave Drying Equipment in Plastic Wood Forming Production Process

The application of microwave dryer in the production process of plastic wood molding, the process of plastic wood molding mainly includes the pulverization, cleaning, drying and granulation of plastic, the drying, processing of wood powder, the compounding of plastic and wood, and the molding process of products.

A core environmental protection process of the drying equipment process, it is the core link to determine the quality of plastic wood, its quality will directly affect the processing technology and product quality of the product.

The selection and treatment of wood flour, the wood powder used in the wood-plastic technology generally does not have strict requirements. Wood powder and various plant fibers of various types of wood can generally be used (sawdust and scrap produced during wood processing) After pulverization, the effect on processing is not large. The main requirement is that the particle size of various wood powders is generally 20-100 mesh. On this basis, it is necessary to ensure that the wood powder and plastic are dried before mixing. Generally, the moisture content of wood flour should be controlled within 3%. The drying equipment can be electrically heated, or dried by microwave heating or naturally dried. The dried wood powder should be stored in a dry place (indoor), and it should not be absorbed twice.

Waste plastic drying equipment. For the wood-plastic technology currently developed and researched, the types of plastics used are generally polyolefin (polyethylene, polypropylene) and polyvinyl chloride. Because these three kinds of plastics occupy most of the production and market of plastics, the development and application of these three kinds of waste plastics have great economic and social benefits. It is important to vigorously develop the blending process of polyolefin and wood flour. In terms of drying of plastics, at present, if it is required to achieve high dryness, it is necessary to combine various drying techniques, such as microwave drying and hot air. A combination of drying equipment or infrared drying equipment.
