Wood-wool, fibre board and method for making same

Abstract

The invention discloses wood-wool, a wood-wool plate and a preparation method thereof. The wood-wool plate comprises wood-wools formed by untwining in the fibre direction; furthermore, the wood-wools are arranged along the fibre direction. Compared with the existing general wood-wool plate, the wood-wool plate prepared by the method of the invention uses generally abandoned single-plate edge angle waste material as raw material and greatly reduces the cost of the wood-wool plate; the usage performance of the prepared wood-wool plate complies with the requirement of the positioning structure wood-wool plate standard (LY / T1580-2000); the wood-wool plate prepared in the fibre direction is equivalent to the solid wood plate on sensing and performance and overcomes the defects of the solid wood plate such as deformation and weather resistant.

Description

technical field [0001] The invention relates to a wood wool, a wood wool board and a preparation method thereof, in particular to a wood wool, a wood wool board prepared from veneer processing waste and a preparation method thereof. Background technique [0002] At present, in the process of veneer processing in my country, the veneer processing factories in China usually select high-grade logs with better material than processing materials, and the best part of the log is the sapwood part, and the logs that can be processed into veneers are rotary cut. 30% of the sapwood shredded veneer processed from gardening or planing and returning to the square, that is to say, nearly 30% of the log sapwood with good quality has become waste and has not been well utilized. These wastes are mainly used The boiler fuel in the factory was burned as cheap fuel, which caused a huge waste of high-grade logs with good materials. [0003] On the other hand, the existing wood wool board has the ...

Problems solved by technology

[0002] At present, in the process of veneer processing in my country, veneer processing factories in China usually select high-grade logs with better material than processing materials, and the best part of the log is the sapwood part, which can be processed into veneer by rotary cutting. 30% of the sapwood shredded veneers processed in the garden or sliced ​​back to the square, that is to say, nearly 30% of the log sapwood with good quality has become waste and has not been well utilized. These wastes are mainly used The boiler fuel used in the factory was burned as cheap fuel, which caused a huge waste of high-grade logs with good materials

[0003] On the other hand, the existing wood wool board has the problem of poor board performance due to the poor quality of the raw material wood wool used

Wood wool, the raw material of existing wood wool boards, is usually sliced ​​from wood. Because the length of the wood segment is relatively short, the length of the wood wool obtained by sliced ​​is also relatively short, mostly 50 cm; wood wool is produced by sliced , the direction of the knife and the direction of the wood fiber form a certain angle, the wood fiber obtained by planing is damaged by inward bending, and the long wood fiber is naturally twisted, and the rigidity of the wood fiber is insufficient. The finished board, the wood wool presents a criss-cross and disorderly network structure, with many unpenetrated mesh holes, which cannot form a frame structure microscopically, resulting in poor strength of the wood wool board.
