Embodiment Construction

[0011] See attached figure 1 , 2 , 3, 4, 5, a kind of manufacturing method of molded solid wood medium-high-density plywood disclosed by the present invention is characterized in that: put the lower density plank or wooden strip 1 in the high-pressure container to pressurize beyond the atmospheric pressure Glue penetration, so that the thermosetting glue solution with fireproofing agent and a certain temperature can quickly penetrate the thickness of the board and blend into the fibrous tissue of the wood at a rate of 9% to 18% of the weight of the formed board. After the wooden boards or wooden strips 1 taken out of the tank are dried at low temperature, they are molded in a hot press according to the compression ratio that can be compressed into medium and high density boards, so that the thermosetting glue 2 can penetrate into the wooden boards or wooden boards. Solid wood medium and high density plywood between strips 1 fiber tissue.

Abstract

The invention discloses a method for manufacturing a high-density glue permeated plate in mould pressing solid wood, which belongs to the technical field of processing of artificial plates and relevant equipment. The method is characterized in that a low-density wood plate or wood strip is placed in a high-pressure container to realize supercharging glue permeation via pressure higher than atmosphere pressure, glue permeation time can be shortened, further, glue can assuredly permeate into seams among fiber tissues of the wood effectively, the wood plate or wood strip dried at low temperature is placed in a hot pressing machine to be compressed into a medium and high-density plate in a mould pressing manner according to a proper compression ratio, and accordingly a finally manufactured medium and high-density glue permeated plate in the solid wood really has performances of no crack, waterproofness and fire protection which do not belong to the solid wood, is high in woodiness feeling and nail-holding ability, has excellent stability, and can be used for replacing increasingly deficient hard wood.

Description

technical field [0001] The invention discloses a method for manufacturing a molded solid wood medium-high density plywood, which belongs to the technical field of wood-based panels and related equipment processing. Background technique [0002] The medium and high density board produced in the prior art is made of wood fiber, which is waterproof, fireproof, crack-resistant, and has poor nail-holding ability, so it is difficult to replace hard wood which is in short supply day by day. Contents of the invention [0003] The invention discloses a method for manufacturing a molded solid wood medium-high-density glue-seeping board. The purpose is to place wood boards or strips with low density in a high-pressure container to pressurize the glue-seeking beyond the atmospheric pressure, so that the fireproofing agent can be added. And the thermosetting glue solution with a certain temperature quickly penetrates the thickness of the board and blends into the fibrous tissue of the ...
