AI Technical Summary

Problems solved by technology

Woodworking boards (commonly known as large core boards) have different materials and densities of solid wood strips inside, and are easy to warp and deform after simple drying treatment; the surface is relatively rough, and a large amount of glue or paint is usually used, which is relatively unenvironmental. High release, pungent odor
Particleboard has a granular structure inside, which is not easy to mill, and it is easy to cause sharp tooth phenomenon when cutting the board, so the requirements for processing equipment are relatively high
Solid wood finger joint board is easy to deform and crack
Good solid wood boards are generally expensive and difficult to promote and use on a large scale
Conventional fiberboard has poor moisture resistance and a large expansion coefficient after absorbing water

Abstract

The invention discloses a production method for a fireproof, flame-resistant, medium-density fiber closet plate. The method comprises the steps of (1) preprocessing of raw materials, (2) screening, (3) steaming and boiling for softening, (4) grinding, (5) sizing and drying, (6) prepressing, (7) hot pressing, (8) sawing and sanding, (9) veneering and hot pressing and (10) edge cutting. In this way,a finished product is obtained. The method disclosed by the invention is characterized in that eucalyptus barks and branches and waste leftover bits and pieces left after panel manufacture are takenas main raw materials, other miscellaneous wood is added and waste is recycled, so wood resources can be utilized fully and effectively; and modified paraffin and flame-resistant urea-formaldehyde resin adhesive are added, so resistance of the product to fire and flame is greatly enhanced. The medium-density fiber cabinet plate is highly resistant to fire, flame and water and low in the content offormaldehyde, so the product is a safe and environment-friendly closet plate.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, in particular to a production method of a fireproof and flame-retardant medium-density fiber wardrobe special board. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. It mainly includes three major categories of products: plywood, shaving (particle) board and fiberboard, with hundreds of extended products and deep-processed products. Plywood is made by steaming and softening logs, rotary cutting into large sheets, and then placing the wood fiber directions perpendicular to each other, bonding them with synthetic resin glue with good water resistance, and then pressurizing, drying, sawing, and surface trimming. of plates. The number of layers is an odd number, generally 3 to 13 layers...
