Problems solved by technology

High-density fiberboard has high density, is difficult to process, and is easy to burst when nailing and installing accessories; while low-density fiberboard has low density, large gaps between wood fibers, and is easy to absorb water and swell, causing the surface covering to fall off or even the board to disintegrate. It is used less in office furniture

Abstract

The invention discloses a production method of a special highly-moisture-proof intermediate-density fiber board for an office table. The method comprises the following steps: (1) preprocessing raw materials; (2) screening; (3) digesting to soften; (4) grinding; (5) applying glue, and drying; (6) pre-pressing; (7) thermally pressing; (8) sawing and sanding; (9) clinging to the surface, and thermally pressing; and (10) cutting the edge to obtain the special board for the office table. According to the method, eucalyptus bark, branches and waste leftovers in board manufacturing are treated as main raw materials; miscellaneous woods such as pine wood, basswood, briar wood, fraxinus mandshurica, beech wood, acer mono wood and lauan wood are added; the wastes are turned into treasures; and the wood resource is fully effectively utilized; hydrogenated rosin and thiourea are added to a moisture-proof urea resin adhering agent, so that the board has the advantages of being environmentally friendly, low in formaldehyde, and outstanding in moisture-proofing performance. The board is outstanding in moisture-proofing performance, high in water resistance, low in formaldehyde content, high in intensity, and high in durability, and is a safe and environmentally-friendly board.

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 special board for desks. 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 a...
