Abstract

The invention discloses a chipboard making method through microwave preheating. The method comprises the processes of wood shaving making, drying and screening, wood shaving gluing, laying and forming, prepressing, hot pressing and later processing. According to the chipboard making method, a chipboard microwave preheating process is additionally set between the laying process and the prepressingprocess, the chipboard is quickly preheated, a surface core layer of a plate blank is heated and subjected to temperature increase at the same time, the initial temperature of the laid chipboard blankduring prepressing and hot pressing is increased, air in the prepressed chipboard blank is reduced, and the heat transmission efficiency during hot press is improved; meanwhile, the heating and temperature increase time of the chipboard blank in a hot press is shortened, the curing speed of an adhesive is increased, the whole time of producing and making the chipboard is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of artificial board manufacture, in particular to a method for preparing particle boards preheated by microwaves. Background technique [0002] Particleboard is a man-made board made of wood or other wood fibers, prepared by shavings, dried and sorted, applied with urea-formaldehyde resin or other adhesives, paved, pre-pressed, and hot-pressed. With the development of the economy and the improvement of people's living standards, the domestic custom furniture industry has developed rapidly. As the main base material of custom furniture, the demand for particleboard is increasing day by day. [0003] At present, the particleboard preparation method in the prior art generally includes the steps of particleboard preparation, drying and screening, sizing, paving and molding, pre-pressing and hot-pressing. Among them, the purpose of pavement molding is to ensure uniform density of the particleboard, to ensure tha...
