Production process for manufacturing cement fibre board from fast growth aspen

Abstract

The invention relates to a processing technique of manufacturing a cemented excelsior board by using fast growing poplar, which is characterized in that the method comprises the following steps: cutting a piece of poplar wood into wood wool by using a wood wool making machine; weighing wood wool and cement required by a single excelsior board; dipping the wood wool into water; fully mixing with the cement in an agitator; uniformly spreading the agitated mixture of the wood wool and the cement in to a mould; sending each finished mould into a cooling press; starting the cooling press to press the loose mixture into solid mixture; placing concrete blocks above mould piles which come out from the cooling press for maintaining the mould piles; detaching board blanks from the mould and drying the same in natural condition; and sizing, trimming and sanding the board blanks, spraying color on the same, and processing corners of the same. The processing technique has the advantages of simple processing technique, small equipment investment, small occupied field and controllable output.

Description

technical field [0001] The invention relates to a production process for making cement wood wool boards from fast-growing poplar, which can be used to produce cement wood wool boards used in building lightweight partition walls and decoration, and belongs to the technical field of wood-based panel manufacturing processes. Background technique [0002] Cement wood wool board is an artificial board made of wood wool and cement as a gelling agent. It has many excellent properties such as heat preservation, sound insulation, sound absorption, and fire prevention. It can be used as a lightweight partition wall of a building or in secondary decoration. Has broad market prospects. At present, the cement wood wool board used in China is almost dependent on imports, and there is no technology and equipment in China that can produce cement wood wool board in batches. Although some European companies have commercialized cement wood wool board production lines for sale, there are two p...

AI Technical Summary

Problems solved by technology

Although some European companies have commercialized cement wood wool board production lines for sale, there are two problems in introducing them into China. One is that the production capacity of European equipment design is very large. For example, the single-shift production capacity of the equipment of the Dutch Aituo company reaches 165m 3 Obviously, emerging markets like China can't digest it; on the other hand, due to the high degree of automation of the equipment, the price is expensive, and it takes up a lot of space, which is not conducive to small and medium-sized enterprises investing in setting up factories.
