Problems solved by technology

All of the above-mentioned products such as lignin, activated carbon, biodiesel, microcrystalline cellulose, and ethanol, which use xylose residue as raw material, have long and complicated technological processes, strict requirements on the environment and control parameters, large waste water discharge, and high energy consumption. , high cost and other factors, industrialization is greatly restricted, and most of them only stay in the laboratory research stage
However, the relevant patents on plywood, particleboard, density fiberboard and other boards prepared by using xylose residue as raw material instead of wood materials have not been reported yet.

Embodiment 1

[0022] 1) Purification of xylose residue: Take 100kg of dry base xylose residue, add 1900kg of industrial water to dilute to a mass percentage concentration of 5%, and continue to stir. According to the action of gravity, the silt, stones, and bricks in the xylose residue , iron and other impurities will settle to the bottom, collect the suspended xylose residue on the upper layer, and obtain 1800kg of purified xylose residue liquid;

[0023] 2) Dehydration: remove most of the moisture in the purified xylose residue liquid with a centrifuge to obtain 180 kg of dehydrated xylose residue with a water mass percentage content of 50%;

[0024] 3) Drying and pulverization: use a vacuum drying box to dry the dehydrated xylose residue, control the operating temperature to 70°C, and dry it until its moisture content is 4.5% by mass, and then pulverize it to 100 mesh with a universal pulverizer to obtain The pulverized xylose residue 94kg is for subsequent use;

Abstract

The invention discloses a technique for manufacturing boards from corn cob residues. The technique for manufacturing the boards from the corn cob residues comprises the steps that purifying, dehydration, drying and smashing of the corn cob residues are conducted, phenolic resin glue is prepared, and the corn cob residue boards are manufactured; and finally, the corn cob residue boards which are porous, light, high in strength and tenacity and capable of being applied to the fields of interior wall decoration, wall sound insulation, heat preservation layers and the like are formed through processing. The corn cob residue boards meet market demands, are wide in application range, good in market prospect, wide in raw material source and low in development cost and have good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of board processing, in particular to a process for preparing boards from xylose slag. Background technique [0002] Plywood, particleboard, density fiberboard and other board materials are generally made of wood or wood chips. Although wood boards are more comfortable to the touch, they are easy to absorb water and swell or dry out and deform, and the strength of wood boards is not strong enough to easily warp and delaminate. The above raw materials for the preparation of boards, whether wood or sawdust, use forest resources, but in recent years, with the development of the economy, people's awareness of environmental protection has increased, energy consumption has increased, and forest resources have become increasingly scarce and scarce. The state's attitude towards "protecting forest resources" has become increasingly clear, and measures to limit and ban forest cutting have also been intensified. The i...
