Problems solved by technology

The use of adhesives is essential in the production of wood-based panels. Flour is often used as an active filler in adhesives. A large amount of flour is consumed every year, which leads to high cost of wood-based panels. It is urgent to find a high-quality active filler. stuffing to substitute for flour

Abstract

The invention relates to a method for producing biomass packing for artificial boards through ultramicro activated eucalyptus bark. The method includes the following steps of S1 raw material crushing,S2 microbiological treatment, S3 immersion treatment, S4 extrusion dewatering, S5 drying, S6 impurity removing, S7 impact crushing and S8 functional modification. The method has the beneficial effects that 1, the eucalyptus bark is used as the raw materials, is circularly processed and used, and replaces flour to serve as the active packing of a wood processing adhesive, and waste is turned intowealth; 2, organic bentonite used in the invention has good dispersibility and suspension stability, alkaline water soluble glucan plays a role of a coupling agent, and the compatibility, dispersibility and blending uniformity of the packing are improved; and 3, through microbiological treatment in the invention, part of the bark raw materials can be degraded, color becomes shallow, meanwhile, cell walls of the raw materials are broken, tannin structures are fully exposed on the surfaces of the raw materials, the efficiency of reaction between the raw materials and formaldehyde in bonding materials is increased, and the formaldehyde removing function of the raw materials is improved.

Description

technical field [0001] The invention relates to a processing technique for biomass fillers, in particular to a method for producing biomass fillers for wood-based panels with ultrafine activated eucalyptus bark. Background technique [0002] Wood-based panels are separated into various shapes of unit materials by mechanical processing of wood fiber raw materials, and then combined and pressed into various panels. The production of wood-based panels utilizes scraps, small-diameter wood, and branch wood produced in the process of wood mechanical processing, which greatly improves the utilization rate of wood resources. There are many types of wood-based panels, commonly used decorative wood-based panels such as particleboard, fiberboard, blockboard, plywood, and fireproof board. Because they have their own different characteristics, they are used in different furniture manufacturing, construction, automobile production and other fields. The use of adhesives is essential in t...
