Abstract
The invention discloses a manufacturing method of a laminated particle board, which comprises the following steps: (1) material preparation: machining crushed wood veneers into wood shavings of which the width is less than 3cm and the length is less than 5cm; (2) drying the wood shavings to a water content of 8-12%, and applying an adhesive, wherein the amount of the applied adhesive is 10-18%, and the adhesive is a urea-formaldehyde adhesive (UF) or a phenol-formaldehyde adhesive (PF); (3) assembling mode: gluing and assembling according to the design requirements of the laminated particle board; (4) hot-compression molding: using a hot press to carry out hot compression on the paved assemblies, wherein the hot compression temperature is 140-160 DEG C, the time is 0.4-0.6min/mm, and the pressure is 2.0-3.0N/mm<2>; and (5) edge trimming: using an edge trimming saw to trim the edge of the laminated particle board subjected to hot-compression molding according to the design requirements, inspecting, and then warehousing. The invention is a manufacturing method of a laminated particle board having high strength, high rigidity and good dimensional stability.
Description
Technical field
The present invention relates to a kind of manufacture method of wood shavings glued board.
Background technology
In recent years, the production development of world's particieboard is rapid, and the production of particieboard accounts for 4% of wood-based plate output usually.Being of wide application of particieboard, particularly in building trade, present particieboard is to be made by gummed by wood shavings, and it does not reach the requirement of present building trade to particieboard: light weight, high strength and high rigidity, dimensional stability are good, corrosion resistant and heat-resisting, sound-insulating and heat-insulating, nontoxic.
Summary of the invention
Technical problem to be solved by this invention provides the manufacture method of a kind of high strength and high rigidity, wood shavings glued board that dimensional stability is good.
In order to solve the problems of the technologies described above, the manufacture method of wood shavings glued board provided by the invention, form by the following step:

(3), assemble pattern: the gluing assembling of designing requirement of pressing the wood shavings glued board;
(4) hot-forming: the wood shavings gummed slab that assembles is carried out hot pressing with hot press, and hot pressing temperature is 140～160 ℃, and the time is 0.4～0.6min/mm, and pressure is 2.0～3.0N/mm
2
(5) saw limit operation: by designing requirement with Sawing machine with hot-forming wood shavings veneer saw limit, check, put in storage then.
Described assemble pattern is: be the wood shavings layer by the centre, the wood shavings layer is upper and lower respectively to be provided with the gluing assembling of one deck veneer, or by clamping a gluing veneer in the middle of two wood shavings layers, the skin of two wood shavings layers is equipped with a gluing assembling of single plank, or the centre is the wood shavings layer, the wood shavings layer upper and lower each gluingly be provided with two layers of veneers assembling.
Adopt the manufacture method of the wood shavings glued board of technique scheme, the wood shavings glued board of producing, owing to be that gummed has veneer, veneer to have the combination of wood shavings layer can improve intensity and high rigidity on the wood shavings layer, dimensional stability is good simultaneously.
The manufacture method of the wood shavings glued board that in sum, the present invention is a kind of high strength and high rigidity, dimensional stability is good.
