Embodiment 1

[0025] Example 1: See figure 1 , the present invention provides the circular production process of wood leftovers to produce Ozon board, comprising the steps of:

[0026] 1) Collection of leftovers: collect wood leftovers in a centralized manner and reserve them for later use;

[0027] 2) Cooking of leftovers: put the collected wood leftovers into a steamer for cooking, the cooking temperature is 80-90°C, and the cooking time is 25-35min;

[0028] 3) peeling of leftovers: peeling the wood leftovers that have been cooked, and removing the outer skin and necrotic parts of the wood;

[0029] 4) Veneer rotary cutting: Fix the treated wood scraps on the veneer rotary cutting device, start the machine, and the rotary knife will peel the wood scraps, and cut the raw materials into 6cm in length, 2cm in width and 0.1cm in thickness sheet, spare;

[0030] 5) Drying of the veneer: the finished sheet is dried by wet drying, so that the moisture content of the sheet is controlled at 1....

Abstract

The invention discloses a circulating production process for an oriented structural board from timber offcut. The circulating production process comprises the following steps of offcut collection, offcut cooking, offcut barking, veneer rotary cutting, veneer drying, veneer neatening, gluing assembly, prepressing, hot pressing, edge cutting, inspection and grading, and packaging and storage. In theprocess of raw material treatment, the steps of offcut cooking and veneer drying are adopted, offcut cooking can effectively remove eggs hidden in the offcut, the service life of timber is effectively prolonged, and the performance of the timber is also promoted; wet drying is adopted for veneer drying, the situation that timber surfaces dry too fast and lead to dramatic surface shrinkage, deformation and cracking, causing product damage or degradation is avoided, or a crust is formed on the surface and prevents overflow of internal moisture; and adhesion agents are rearranged and have good adhesion and flame resistance, the performance of the oriented structural board after forming is guaranteed, meanwhile the formula of the adhesion agents does not contain formaldehyde or other toxic substances, and the environment friendliness of the oriented structural board is effectively promoted.

Description

technical field [0001] The invention relates to the technical field of OSB board production, in particular to a circular production process for producing OSB boards from leftover wood. Background technique [0002] Ozon board is a new type of board that came from Europe and developed rapidly internationally in the 1970s and 1980s. The application of Ozon board in furniture has achieved unprecedented development. Many large furniture companies have begun to use Ozon board. Furniture made of MDF is favored by consumers because it has no formaldehyde release, is durable, and is lighter in weight and better in flatness than furniture made of MDF. It uses small-diameter timber, thinning timber, and wood core as raw materials. It is processed into 40-100mm long, 5-20mm wide, and 0.3-0.7mm thick flakes through special equipment. After deoiling, drying, sizing, and directional paving A kind of directional structure plate made by , hot pressing and other processes. The shavings on ...
