Method for manufacturing oriented strand board

Abstract

The invention discloses a method for manufacturing an oriented strand board. The method comprises the following steps of obtaining a straw raw material; carrying out fixed-length cutting treatment onthe straw raw material so as to form fixed-length straws; placing the fixed-length straws in a surface layer wet stock bin for primary storage; drying the fixed-length straws after primary storage; screening the dried fixed-length straws; placing the screened fixed-length straws in a surface layer dry stock bin for secondary storage; carrying out sizing treatment on the fixed-length straws after secondary storage; carrying out oriented paving on the fixed-length straws subjected to sizing treatment; and carrying out pre-pressing treatment on the fixed-length straws subjected to oriented pavingand a shaving core layer subjected to paving treatment so as to form a shaving board blank and carrying out continuous autoclaving treatment on the shaving board blank. The method for manufacturing the oriented strand board has the advantages that the product quality of the oriented strand board can be ensured, meanwhile, a precious wood material is partially replaced by the straw raw material, so that a large amount of wood resources can be saved, and the manufacturing cost of the oriented strand board can be lowered.

Description

technical field [0001] The present application relates to the field of building board manufacture, and more specifically, relates to a method for manufacturing oriented strand board. Background technique [0002] Particleboard is widely used in construction, decoration and other fields. The particleboard structure is divided into multi-layer structure and gradient structure. The multi-layer structure particleboard is composed of the upper and lower surface layers and the middle core layer. The upper and lower surface layers are usually relatively fine shavings, which are convenient for sanding and subsequent deep processing. The core layer is made of larger shavings to enhance the physical and mechanical properties of the product; It is also fine shavings, gradually transitioning to large shavings in the middle core layer, and the particleboard with gradual structure has no obvious layering. In recent years, with the change of people's needs, new types of particle boards s...

Problems solved by technology

[0004] In the existing technology, when producing oriented strand board, it is necessary to use a large amount of high-quality wood to produce large flakes that meet the requirements. With the production and manufacture of a large number of oriented strand boards, the consumption of wood resources in my country is also increasing, which is very unfavorable to the ecological environment. construction and development
