Embodiment 1

[0027] A method for making plywood by using eucalyptus sawdust, the specific steps are as follows:

[0028] 1) Pre-treatment of sawdust: Soak Dumu wood chips in lime water for 10 minutes, then remove and wash them with clean water for 2 times, each time for 5 minutes, remove Dumu saw chips from clean water, dry them in the air, and then grind them with a pulverizer The dried Dumu wood chips are crushed into 200 meshes.

[0029] 2) Surface treatment of sawdust: add sawdust starter to the dulca sawdust obtained in 1) at a mass ratio of 8:1, add water and mix evenly, keep the humidity of dulcis sawdust at 60%, and ferment at a temperature of 60°C for 3 hours , and then stir and wash the eucalyptus sawdust with clear water for 2 times, remove the eucalyptus sawdust, dry it with a dryer until the water content is 5%, and the drying temperature is 90°C, and then sterilize the eucalyptus sawdust to obtain the surface Dimpled dunwood chips that have been corroded.

Abstract

The invention belongs to the technical field of plywood machining, and particularly relates to a method for manufacturing a plywood by using pyrus betulaefolia saw dust. The method comprises the following five steps of saw dust pretreatment, saw dust surface treatment, adhesive preparation, molding and veneer pasting, and finally, the pyrus betulaefolia saw dust is successfully manufactured into the plywood. According to the method, the pyrus betulaefolia saw dust is recycled, the resource utilization rate is high, the waste is reduced, the effects of being energy-saving and environment-friendly are achieved, moreover, the manufactured plywood is high in strength, strong in insect-pest-resistant capability and long in service life.

Description

【Technical field】 [0001] The invention relates to the technical field of plywood processing, in particular to a method for making plywood by using eucalyptus sawdust. 【Background technique】 [0002] Dumu wood is fine and delicate, and it is mostly used for carving. The carved Dumu wood chips are generally piled directly into the garbage dump, which takes up a lot of space, and the wood will rot after a long time of stacking, which greatly wastes wood resources. The existing wood chips The method of making the plywood has poor supporting effect, low strength of the plywood, and is easy to deform under heavy pressure, and even cause brittle fracture. 【Content of invention】 [0003] The object of the present invention is to solve the above problems by providing a method for making plywood by using eucalyptus sawdust to solve the problem of waste of eucalyptus sawdust. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as f...
