Problems solved by technology

[0012] The particleboard disclosed in the above-mentioned document discloses the method of pressing into particleboard by using disposable chopsticks, oil palm and low specific gravity wood materials, but there is no report of using the leftover wood of the fast-growing eucalyptus board production process as raw material to produce the whole eucalyptus leftover particleboard
[0013] Moreover, in the existing particleboard production process, most of the leftover materials are used. Because there is more bark mixed in, the performance is quite different from that of the wood core. If they are hot-pressed together, the softness and hardness of each part of the produced particleboard will be different. , the degree of water absorption and strength are not the same (the bark is softer and the wood core is harder), so the quality of the produced particleboard is difficult to guarantee, and the removal of the bark is currently a technical problem that is not easy to solve

Embodiment 1

[0059] The method for producing environmentally friendly particle boards by continuous hot pressing of whole eucalyptus wood scraps comprises the following process steps:

[0060] (1) Rough separation of raw materials

[0061] After the production of eucalyptus plywood, leftovers, cutting materials, and eucalyptus sprigs are separated from metal and stone, chipped, and simply screened, they are sent to the wood chip storage transition warehouse for storage, and then transported to the planer by the screw conveyor for planing. Then it is sent to the wet shavings transition warehouse by the scraper conveyor for storage; the moisture content of the wet shavings should be kept below 45%;

[0062] The leftovers are waste materials that cannot be utilized in the process of producing plywood by rotary-cut eucalyptus boards; the cut-offs are the residues in eucalyptus logging or rotary-cutting processing, such as timber truncated ends and board edges; described eucalyptus wood Twigs ...

[0087] The method for producing environmentally friendly particle boards by continuous hot pressing of whole eucalyptus wood scraps comprises the following process steps:

[0088] (1) Rough separation of raw materials

[0089] After the production of eucalyptus plywood, leftovers, cutting materials, and eucalyptus sprigs are separated from metal and stone, chipped, and simply screened, they are sent to the wood chip storage transition warehouse for storage, and then transported to the planer by the screw conveyor for planing. Then it is sent to the wet shavings silo by the scraper conveyor for transitional storage; the moisture content of the wet shavings should be kept below 45%;

Abstract

The invention discloses a method for producing an environment-friendly particle board through continuous hot pressing of a total eucalypt wood leftover material. The method comprises the procedures like chipping, flaking, drying, two-time screening (veneer removing and grit removing), sorting and polishing, mixing glue, hot press molding, aftertreatment, sanding and board selecting. According to the method, the eucalypt wood leftover material is fully utilized, and the wood waste is reduced; the produced particle board reaches the national standard and meets the GB / T4897-2015 requirement in Particle Board and the GB18570-2001 requirement in Indoor Decorating and Refurbishing Materials Limit of Formaldehyde Emission of Wood-based Panels and Finishing Products; melamine impregnated paper can be pasted on the surface of a produced panel; and the particle board is manufactured into high-end desk panels, wardrobe and cabinet panels, partitions, wood floors, ceilings, and other panels.

Description

technical field [0001] The invention belongs to the field of wood-based panel manufacturing, in particular to a method for continuously hot-pressing whole eucalyptus leftovers to produce environmentally friendly particle boards. Background technique [0002] Particleboard is one of the wood-based panels. Particleboard (Particle board), also known as particle board, particle board, particle board, wood wool board, etc., is made of wood or other lignocellulose as the basic material. , After applying the adhesive, it is a wood-based panel that is glued together under the action of temperature and pressure. Because the particleboard structure is relatively uniform and the processing performance is good, it can be processed into large-format boards according to needs. It is widely used in furniture, office, wooden floor and interior decoration and other fields. It can also be used in the construction industry and the manufacture of trains and car carriages. [0003] The raw mate...
