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

Embodiment 1

[0049] A method for producing a high-moisture-proof medium-density fiber wardrobe special board, the specific steps are:

[0050] (1) Raw material pretreatment: Mix eucalyptus scraps and other miscellaneous woods evenly at a weight ratio of 1:03, cut into pieces with a length less than 5cm and a width less than 1cm;

[0051] The eucalyptus leftovers are eucalyptus bark, branches and waste leftovers from making boards; the miscellaneous woods are pine and birch, and the wood is left to air for 16 days before use.

[0052] (2) Sieving: Sieve the wood chips obtained above to remove silt and debris with a particle size of less than 0.2cm, and remove iron through strong magnetic attraction;

[0053] (3) Cooking and softening: transport the wood fragments into the cooking tank, add an appropriate amount of water to soak for 10 minutes, then pass steam into the cooking tank, keep the pressure in the tank at 0.16Mpa, cook for 4 minutes, and obtain cork with a water content of 85% afte...

Abstract

The invention discloses a production method of a high-moisture-proof and medium-density fiber wardrobe special plate. The production method comprises the following steps of (1) raw materials pretreating, (2) screening, (3) cooking and softening, (4) grinding, (5) gluing and drying, (6) prepressing, (7) hot pressing, (8) sawing and sanding, (9) veneering and hot pressing, (10), edge sealing, and afinished wardrobe special plate is obtained. According to the production method, barks and branches of eucalyptus and waste leftover materials left in the plate manufacturing process are taken as mainraw materials, then pine wood, basswood, birch wood, weeping willow wood, zelkova wood, aceraceae wood, willow wood and the like are added, the waste is changed into wealth, and the wood resources can be fully and effectively utilized; the produced medium-density fiber wardrobe special plate has the advantages of being good in moisture-proof performance, good in water resistance, low in formaldehyde content, high in strength and good in toughness, and the wardrobe special plate is safe, environment-friendly, attractive, wear-resistant and practical.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, in particular to a production method of a high-moisture-proof 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, which ar...
