Problems solved by technology

[0003] However, due to its low density, loose tissue fibers, low hardness, and insufficient strength, (natural) softwoods have failed to meet the safety standards for fire prevention, fire resistance and strength of products produced by traditional techniques. Limits the scope of use of softwood and affects the economic value of a large number of discarded softwood scra...

Embodiment Construction

[0027] Combine the following figure 1 As shown, the production method of the recycled fire-proof and flame-retardant wood of the present invention is introduced in detail.

[0028] In the production method of the present invention, the raw materials that can be used as the recycled fire-resistant and flame-retardant wood of the present invention are very extensive, and can be discarded wood scraps and waste materials, and these woods can be soft wood or hard wood. For example, eco-friendly softwoods with a low density, or hardwoods with a higher density can be used.

[0029] These timber materials are mainly derived from:

[0030] a. Wood with defects (for example, bursts, dead knots, bug roars, etc.);

[0031] b. Defective products that need to be scrapped due to processing errors during the production process;

[0032] c. Head and tail scraps of wood;

[0033] d. Raw materials whose size is not suitable for the production of established products;

[0034] e. Wooden beam...

Abstract

The invention relates to a method for reproducing flame-proof wood, comprising following steps: (1) lengthening short wood with joint method, (2) thickening thin wood with montage technique, (3) widening narrow wood with montage technique; then treating with flame-proof drug and preparing needed flame-proof raw material.

Description

technical field [0001] The invention relates to a production method of recycled wood, in particular, the invention relates to a method of recycling fire-resistant and flame-retardant wood by using discarded wood fragments and waste materials as raw materials. Background technique [0002] As we all know, natural wood can be divided into hardwood and softwood. And soft wood is because its natural growth period is short, and cost is low, is used in a large amount in less demanding industries, for example, is used as the product of furniture industry, and produces a large amount of processing discarded soft wood fragments, waste material. [0003] However, due to its low density, loose tissue fibers, low hardness, and insufficient strength, (natural) softwoods have failed to meet the safety standards for fire prevention, fire resistance and strength of products produced by traditional techniques. The scope of use of softwood is limited, and the economic value of the recycling ...
