Method of preparing full bamboo or bamboo wood composite oriented structure shaving board

Abstract

Belonging to the field of the production techniques of composite artificial boards, the present invention relates to a production method of an oriented structural bamboo or bamboo-wood flakeboard, in particular to a production method of an oriented structural flakeboard using bamboo and bamboo wood as materials. The method includes processes, such as cutting off, flaking, drying, sizing, assemblyand hot-pressing formation, cutting, etc. The production technique is simple, the production cost is low, the product is high-quality and cheap, the choosing of materials is convenient, and mass production can be realized. The physical property of the product measures up to the standard of an oriented structural flakeboard, and the board surface is dense and even, thus achieving waterproof, dampproof and antifouling properties. After being cut and grooved, the product can be directly used for containers, carriage bottom boards, furnitures, packing boards, etc., and moreover, the product does not need surface processing or does not need to be added with a wood veneer and be processed in order to be directly covered with a film or veneered with other panels.

Description

technical field [0001] The invention belongs to the field of composite wood-based board manufacturing technology, in particular to a method for manufacturing an oriented particle board using bamboo and logs as materials. Background technique [0002] At present, most OSB materials in the world are made of pine wood that is more than 30 years old. Since pine wood is a medium-low density cork, the compressive strength, elastic modulus and physical properties of the OSB produced by it still cannot reach 750KG / M 3 Hardwood physical performance standards above the density are still unable to replace a large number of solid hardwoods used for load-bearing and structural. As we all know, hardwoods are mostly produced in virgin forests, and their growth period is mostly more than a hundred years. These trees are our precious biological resources. Once cut down, it will be difficult to restore and have a serious impact on the ecological environment. And because the manufacture of ...

Problems solved by technology

And because the manufacture of wood OSB is limited to softwood materials such as pine and fir, the production process is complex, the manufacturing cost is high, and the hardness and strength of the product are limited to a certain extent. The product is difficult to promote as a substitute for hardwood. At present, wood orientation Structural particle board can only be used as low-cost wood-based panels to replace plywood in packing boxes, construction wooden houses, etc.; in China, because wood resources are scarce and precious, the production of low-value wood-based OSB is not in line with economic costs; therefore, by 2007 So far, there is no large-scale wood OSB enterprise in China
