Problems solved by technology

Practice has proved that the stability of this kind of particleboard is poor, and it is relatively easy to peel off, and it will absorb a lot of water after being exposed to water, making the product unusable
That is, the strength is poor, the processing performance is not good, and the waterproof performance is not good

Embodiment Construction

[0008] Below in conjunction with embodiment the present invention is further described: low toxicity waterproof homogeneous particle board comprises the following steps: (1) raw material selection and chipping; a, raw material maximum cross-sectional area is no more than 420cm 2 (For small-diameter wood, the maximum diameter shall not exceed 23cm). When approaching this surface, the length should not exceed 2 meters. The moisture content of the cutting raw materials is about 40% relative to the moisture content, 1 / 2 of which is decayed, and the afforestation cuts with large grains cannot enter the chipper. b. For the branches and branches whose curvature exceeds the standard, they should be cut off with an electric chain saw on the feeding ground to reduce the curvature and then enter the chipper. The length is less than 4 meters. (2) Preparation and dry sorting of shavings: The raw wood or branch wood is planed into shavings through ring shavings, and the thickness is 0.2-0.4...

Abstract

The invention refers to a kind of low-toxin even water-tight flakeboard. The wood is planed, grinded, and added in several chemical material, and shaped. The structure of the product is between middle density fiber board and flakeboard, it hasn't prominent shade structure, and it has a high intensity and processing performance. The standard length: above 915 mm; width: above 915 mm; thickness 4 mm.

Description

Technical field: [0001] The invention relates to a particleboard, in particular to a low-toxic waterproof homogeneous particleboard, which belongs to the field of wood processing. Background technique: [0002] The current particleboard is mainly composed of three layers, of which the upper and lower layers are made of the same material, that is, the particles are uniform and relatively small, while the particles of the middle core layer are rougher than the particles of the upper and lower layers, and paraffin wax is used as a waterproofing agent. Practice has proved that the stability of this kind of particleboard is poor, and it is relatively easy to peel off, and it will absorb a lot of water after being exposed to water, causing the product to be unusable. That is, the strength is poor, the processing performance is not good, and the waterproof performance is not good. Invention content: [0003] The purpose of the present invention is to provide a low-toxic waterpro...
