Abstract

The invention discloses a production method of a high strength particleboard of impregnating resin inside sawdust tissue, belonging to the technical field of artificial wood-based panel machining. The invention is characterized in that resin solution is sprayed on sawdust or wood chips and wood bran; a pre-pressure is added by mixing, or the sawdust or the wood chips and the wood bran, which are sprayed with the resin solution, are wrapped in a grid-wire plate to produce a plurality of mixed wire rolls to be ranked for prepressing; and the optimal liquid gel applying amount is obtained based on the condition that the gel does not escape out of a sawdust work-board or a mixed wire roll work-board when in prepressing and the solution is close to a saturation state in the work-boards so that the resin solution is pressed in the sawdust tissues through the prepressing to be pressed into a high strength resin modified panel of the impregnating resin inside the sawdust tissue by drying and solidifying on a pressing machine production line at high temperature, and the high strength resin modified panel enables soft woods to be modified into hard woods, thereby supplementing the deficiency in the prior art. The produced wood particleboard panel has the advantages of compacting, strong nail-holding strength and waterproof performance, and can be used for replacing hard wood plates.

Description

Wood is cut the high-strength shaving board manufacture method of impregnated resin inside sawdust tissue

Technical field

Wood disclosed by the invention is cut the high-strength shaving board manufacture method of impregnated resin inside sawdust tissue, belongs to the artificial board processing technique field.

Background technology

The particieboard of Sheng Chaning in the prior art is by wood being cut or wood chip and wooden chaff carry out drying, again through making water-soluble glue be sprayed at that wood is cut or puddle on the surface of wood chip and wooden chaff, and the plate that utilizes Flakeboard Product Line to be pressed into through hot setting.Because its glue-applying technique, be glue to be sprayed at wood is cut or puddle on the surface of wood chip and wooden chaff, play be make wood cut or wood chip and wooden chaff between the connection effect, cut the gummed effect of playing improved wood in the tissue and can not be immersed in wood, so, the particieboard of producing, its internal bond strength are weak, nail-holding ability is little, are difficult to be used for instead of wood plate.

Summary of the invention

Wood disclosed by the invention is cut the high-strength shaving board manufacture method of impregnated resin inside sawdust tissue, its purpose:, produce a kind of wood and cut impregnated resin inside sawdust tissue and make soft timber be modified as to the high-strength resin-modified sheet material of hard wood through improving the particieboard production technology.

And method disclosed by the invention, its advance is: take precompressed that resin solution is immersed in wood and cut in the tissue, the connection area of resin in certain cube volume is increased, played the gummed effect that soft timber is modified as to hard wood, remedy deficiency of the prior art with this.

Description of drawings

Accompanying drawing 1 is cut high-strength shaving board manufacture method embodiment one schematic diagram of impregnated resin inside sawdust tissue for wood disclosed by the invention;

Accompanying drawing 2 is cut high-strength shaving board manufacture method embodiment two schematic diagrames of impregnated resin inside sawdust tissue for wood disclosed by the invention.

In accompanying drawing 1,2,1 cuts blanket for wood; 2 cut or wood chip and wooden chaff for wood; 3 cut in-house resin for being immersed in wood; 4 is the mixed wire volume blanket; 5 is mixed wire volume.

The specific embodiment

See accompanying drawing 1,2, wood disclosed by the invention is cut the high-strength shaving board manufacture method of impregnated resin inside sawdust tissue, it is characterized in that: through improving the particieboard production technology, resin solution is sprayed at that wood is cut or wood chip and above the wooden chaff 2, set up precompressed through blending, the wood that perhaps will be sprayed with resin solution is cut or wood chip and wooden chaff 2 are made several mixed wire volumes 5 for winding up to line up and carry out precompressed in the grid filament plate, during with precompressed resin solution do not overflow that wood is cut blanket 1 or mixed wire volume blanket 4 and solution in blanket near saturated be the best of applying liquid glue amount, with this resin solution 3 is cut in the tissue to being squeezed in wood through precompressed, through super-dry, solidify through the press production line high-temperature again, be pressed into a kind of wood and cut the soft timber that then makes of impregnated resin inside sawdust tissue and be modified as to the high-strength resin-modified sheet material of hard wood.

And wood disclosed by the invention is cut the high-strength shaving board manufacture method of impregnated resin inside sawdust tissue, its advance is: have the wood of resin solution to cut or wood chip and wooden chaff enforcement precompressed to sprinkling, resin solution is immersed in wood to be cut in the tissue and the connection area of resin in certain cube volume is increased, play the gummed effect that soft timber is modified as to hard wood, thereby remedied deficiency of the prior art.The Chipboard of producing thus, closely knit, nail-holding ability is strong, waterproof, can be used for replacing the hard plank.

Claims

1. high-strength shaving board manufacture method that wood is cut impregnated resin inside sawdust tissue, it is characterized in that: through improving the particieboard production technology, resin solution is sprayed at that wood is cut or wood chip and above the wooden chaff (2), set up precompressed through blending, the wood that perhaps will be sprayed with resin solution is cut or wood chip and wooden chaff (2) are made several mixed wire volumes (5) for winding up to line up and carry out precompressed in the grid filament plate, during with precompressed resin solution do not overflow that wood is cut blanket (1) or mixed wire volume blanket (4) and solution in blanket near saturated be the best of applying liquid glue amount, with this resin solution (3) is cut in the tissue to being squeezed in wood through precompressed, through super-dry, solidify through the press production line high-temperature again, be pressed into a kind of wood and cut the soft timber that then makes of impregnated resin inside sawdust tissue and be modified as to the high-strength resin-modified sheet material of hard wood.
