Method for manufacturing environmental-protection anti-deformation board at low carbon

Abstract

The invention discloses a method for manufacturing an environmental-protection anti-deformation board at low carbon; timber resources are not inexhaustible resources, so the timber resources have the problems of high demand and high cost. The method comprises the following steps: S1, performing rotary cutting on logs into veneers by a rotary cutter; grading the veneers; drying the veneers until moisture content is lower than 12 percent; coating surface layers and a middle layer with glue, pressing to manufacture a composite board, and cutting into battens which are equal in specification; selecting three layers of cross grain arranged battens; putting one of the three layers of cross grain arranged battens in the middle, and putting the remaining two layers of cross grain arranged battens on the surface layers or inner layers of the surface layers; pressing the three layers of cross grain arranged battens into an anti-deformation board by a hot press; standing for more than 15 days for curing; cutting into broad battens according to fixed length, coating with the glue, and manufacturing an anti-deformation board by an automatic board jointing machine; cutting off the redundant four sides, and sanding with a sanding belt. According to the manufacturing method disclosed by the invention, valuable timber resources are replaced by fully utilizing common timber resources, and therefore the resources are saved; waste is turned into treasure, forest resources are protected strongly, and the cost is reduced.

Description

technical field [0001] The invention relates to a production technology of an anti-deformation plate, in particular to a low-carbon method for manufacturing an environment-friendly anti-deformation plate. Background technique [0002] With the rapid development of the global economy and the continuous improvement of people's living standards, human consumption needs and desires are also growing uncontrollably, which has also brought enormous pressure to our earth. Global warming, carbon dioxide emissions Every day. Therefore, the entry of human beings into a low-carbon and environmentally friendly life is a hot topic of concern all over the world. Experts pointed out that the core of low-carbon economic development lies in low emission, high absorption and "carbon sustainability", and forest resources will play an important role and far-reaching significance in this regard, which is of great significance to the realization of low emission and high absorption of greenhouse g...

Problems solved by technology

With the improvement of people's living standards, human beings' demand for high-grade wood products is also increasing day by day. However, due to the plight of our country's original forest resources being reduced year by year, and the imbalance of harvesting and breeding, the supply of wood is very scarce.

As we all know, forest trees can absorb carbon dioxide, release oxygen, and purify the air. Timber resources are not inexhaustible resources. Therefore, relevant state departments attach great importance to the issue of saving timber resources and have issued relevant laws and regulations. The policy strictly restricts the harvesting of timber, and even the policy of returning farmland to forests, so there is a problem of high demand and high cost of timber resources

[0003] However, artificially planted fast-growing forests such as roadside poplars, sycamore trees and paulownia trees in front of and behind villages have become useful, but people often use them for low-level The purpose is not to burn it as fuel and make it into plywood, or to use it for one-time use such as outer packaging and building templates. The utilization rate is extremely low, which greatly wastes wood resources.

[0004] At present, during the processing process of plywood factory, veneer factory and multi-layer board factory, some second and third-grade veneers are due to uneven thickness, abnormal color and scarring Too many, not environmentally friendly and other factors have few uses. Some are used for low-grade plywood for one-time use, and some are used as garbage storage corners. They often end up worrying because they cannot find customer resources. After a long time, they will become moldy and deteriorate, so they can only be used as burners. The wood is burned, which not only pollutes the environment, but also greatly wastes wood resources. The core materials commonly used in wooden doors on the market are mostly filled with honeycomb paper or waste materials. Although its price is low, it is not strong, durable, anti-theft, and Environmental protection, unsightly, easy to foam and deform when exposed to moisture; and the Sauerland hollow particleboard imported from Germany, although it solves the phenomenon of slight substrate deformation and cracking, and has better flatness, but its price is more expensive, and it is not anti-theft and waterproof. , the problems of deformation after being exposed to moisture and poor nailing properties have not been resolved
