Method for producing fiber/particle boards

Abstract

The invention belongs to the field of artificial board manufacturing and particularly relates to a method for producing fiber / particle boards by fiber and particles. The method comprises the following technological steps: a, hot-grinding screened wood chips into fiber slurry, gluing the fiber slurry and glue-mixing through a glue tube in a slurry outlet, feeding the glued slurry into a drier for drying under the action of vapor pressure, and then, carrying out the surface layer laying at the front part and rear part of the laying part of a laying conveyor belt; b, conveying particles into a glue mixer to carry out the gluing and glue-mixing processes, then, conveying to a roller drier for drying, and conveying the dried particles to the middle part of the laying part of the laying conveyor belt to carry out the core layer laying; and c, pre-pressing the laid plate blank, conveying the laid plate to a hot press to carry out the one-step hot-press forming process, so as to obtain the fiber / particle boards. The fiber / particle boards produced by the method have the advantages of low cost, high strength, smooth surface, good bonding property and higher anti-ageing performance.

Description

technical field [0001] The invention belongs to the field of manufacturing artificial fiber composite boards, and in particular relates to a production method for preparing fiber particle boards by using fibers and shavings. Background technique [0002] At present, the furniture manufacturing industry uses a large amount of particleboard and medium density fiberboard. Comparing the two, the mechanical properties of particleboard are better than that of medium density fiberboard, but the surface is not as fine as medium density fiberboard. When there are higher mechanical performance requirements, it is more appropriate to use particleboard; when there are delicate engraving and higher surface bonding performance requirements, it is more appropriate to use medium density fiberboard. However, in actual use, medium density fiberboard and particleboard are not suitable for both high mechanical performance requirements and fine engraving and high surface bonding performance req...

AI Technical Summary

Problems solved by technology

Although the composite board of this structure successfully complements the defects of medium density fiberboard and particle board, the raw material cost of the furniture factory has increased by using this method to produce composite boards. At the same time, corresponding cold presses and training related Operators increase the investment cost, and in the process of use, the bonding strength between the layers is poor, and the aging of the adhesive layer is likely to cause problems such as structural degumming due to the influence of the environment.
