Embodiment 1

[0032] Such as image 3 as shown, Diatomite wood-based fiberboard through 1), slicing: the three leftovers such as branch wood produced in forestry are cut by a chipper into wood chips of qualified size, uniform, and even and smooth artwork; the specifications are: length 16-30mm, width 15mm -25mm, thickness 3-5mm;

[0033] 2) Thermal grinding: The wood chips that have been cooked at a high temperature of 165-175°C and high-pressured at 0.75-0.85MPa are separated into fibers by a thermal grinding machine, and the fibers are added with urea-formaldehyde resin adhesive, waterproofing agent, and silicon before entering the drying pipeline through the spray pipe. Algalite additive, sizing rate 200 -240 kg / m 3 , waterproofing agent (paraffin) is 6-8 kg / m 3 1. Diatomaceous earth is added at 1-30% by weight per ton of dry fiber.

[0034] 3) Drying: The fiber entering the drying pipe should have an inlet temperature below 175°C, an outlet temperature of 50-70°C, and a wind speed ...

Abstract

The invention relates to a processing method of a diatomite wood-based fiberboard. The processing method is characterized by comprising the steps of chipping, hot grinding, drying, fiber blowing, paving and molding, hot pressing, cut-off sawing, cooling, sanding and warehousing. By modifying the fiberboard with medium and high density by using the diatomite, the new compound-type board has the additional functions of unlikely combustion, lightness, no toxicity and environmental friendliness, can be used for regulating the indoor humidity, absorbing and decomposing indoor substances causing human allergy and eliminating indoor toxic gases. Besides, three wastes in forestry are efficiently developed and waste woods are utilized.

Description

technical field [0001] The invention relates to a processing method for a diatomite wood-based fiberboard, which belongs to the field of efficient development and comprehensive utilization of resources. Background technique [0002] Medium and high-density fiberboards are widely used due to their excellent physical properties, but ordinary medium and high-density fiberboards as wood raw materials have many defects, such as the ability to release toxic and harmful substances such as formaldehyde and benzene, polluting the use environment; flammable and so on limit its application in many fields. Therefore, the development of diatomite wood-based fiberboard can not only meet the various functional requirements of users for products, but also fill the gaps in this project in our country. Contents of the invention [0003] The purpose of the present invention is to provide a method for processing diatomite wood-based fiberboards. By using diatomite to modify medium and high-d...
