Manufacturing method of environment-friendly plywood

Abstract

The invention discloses a manufacturing method of environment-friendly plywood. The method comprises the steps of veneer screening, core gumming, prepressing and hot pressing, ash scraping, veneeringand dull polish operation, side stiffening and polishing. The method has the beneficial effects that glue used in the process of preparing blank plywood that is the process of splicing eucalyptus woodveneer is E1 and E2 environment-friendly glue (melamine modified urea-formaldehyde resin adhesive), the water resistance of the plywood can be improved, harmful gas like formaldehyde can be subjectedto gathering and absorbing, and the threatens to the person can be reduced; C, according to the customer or product application needs, the inner density of the plywood can be controlled; E, it is ensured that redundant harmful gas cannot be discharged into atmosphere; F, the whole stability and firmness of the plywood are ensured, and it is ensured that the detached plywood can be secondarily used after adjustment; E and G, dust can be effectively reduced, and safety of the operator is protected; and D, the life safety of the worker is protected, ash scraping is facilitated, and work efficiency is improved.

Description

technical field [0001] The invention relates to a method for manufacturing plywood, in particular to a method for manufacturing an environment-friendly plywood, and belongs to the technical field of environment-friendly boards. Background technique [0002] With the implementation of the reform and opening policy, the real estate industry continues to heat up, the hotel industry, furniture industry, and interior decoration industry are developing rapidly, and my country's plywood industry is also developing rapidly. The board has the characteristics of small deformation, large format, convenient construction, not easy to warp, high tensile strength of transverse grain, etc., and is widely used in packaging, furniture, military industry, ships, carriages and other industries. [0003] However, the purity of the board obtained by the existing plywood manufacturing method is not high, and it is not environmentally friendly and does not meet the green concept. Therefore, an envir...

AI Technical Summary

Problems solved by technology

[0003] However, the purity of the board obtained by the existing plywood manufacturing method is not high, and it is not environmentally friendly and does not meet the green concept. Therefore, an environmentally friendly plywood is needed to solve the problem. First, because the board will produce a lot of dust in the process of surface treatment , will cause certain troubles to the environment, and a large amount of sawdust will also pose a threat to the human body. Second, the boards obtained by the existing plywood manufacturing methods cannot be re-used, and most of them cannot be reused after use, which results in resources. Waste, its 3rd, the sheet material obtained by the manufacturing method of existing plywood has defects in moisture resistance and waterproof, and is easy to rot
