Method for producing finished product or semi-finished product technological board by using waste materials

Abstract

The invention relates to a method for producing a finished product or semi-finished product technological board by using waste materials. The method comprises the following technological steps of: preparing materials; collecting the waste materials; cutting and crushing or breaking the collected waste materials; screening crushed materials with qualified size by using a screening machine; heating and softening the crushed materials; allowing the materials to enter a defibrator and performing hot grinding to form fibriform pulp; performing gluing by using an environment-friendly adhesive, wherein the applying quantity is 30 to 40 percent; drying, wherein the drying degree is that the water content is equal to or less than 5 percent; prepressing to form blank boards; performing hot moulding by using a hot press; and performing postprocessing to form the finished product. By the method, various technological boards can be manufactured by using the waste materials such as offcut of various materials, wood shavings, sawed bran, branches, straws, rice straws and the like. The method has the advantages of forming at a time and discarding the traditional process of sawing, planing and chiseling during production so as to improve production efficiency along with simple process, low cost and environmental friendliness.

Description

(1) Technical field [0001] The invention relates to a method for processing and manufacturing craft boards, in particular to a method for producing various finished or semi-finished craft boards by using waste raw materials. (2) Background technology [0002] With the progress of society and the improvement of living standards of urban and rural people, the demand for craft boards as decorations is also increasing. However, the existing production of various finished or semi-finished craft boards, such as photo frames, picture frames, drawer panels, etc., is based on natural forest wood or artificial boards as raw materials, and is produced by sawing, planing, carving, chiseling and other production processes. The craft board unit is divided into pieces, and then assembled into craft board semi-finished products or finished products. This has disadvantages: First, due to the long drying time of wood (the craft board made of wood with insufficient dryness is easy to deform), ...

Problems solved by technology

However, the existing production of various finished or semi-finished craft boards, such as photo frames, picture frames, drawer panels, etc., is based on natural forest wood or artificial boards as raw materials, and is produced by sawing, planing, carving, chiseling and other production processes. The craft board unit is divided into pieces, and then assembled into craft board semi-finished products or finished products. This has disadvantages: First, due to the long drying time of wood (the craft board made of wood with insufficient dryness is easy to deform), the production of craft board produced by traditional technology The cycle is long; the second is that the loss of raw materials is large and the utilization rate is low, especially when producing craft board parts (unit parts) with complex shapes and carved patterns. chiseling, the production efficiency is low, and a large amount of leftover materials, wood shavings, and shavings are produced during the production process. These residues are generally not used effectively, and most of them are thrown away or burned, which makes a large waste of scarce wood resources. At the same time, it is not conducive to the protection of forest resources, and has a relatively large impact on the ecological environment; the third is that the production cost is high, so that the sales price is also high; the fourth is that the existing artificial boards have poor moisture resistance and usually contain a large amount of formaldehyde. Waste will cause serious environmental pollution
