A Restoration Method for Reducing Air Bubbles in Plank

Abstract

The invention discloses a repairing method for reducing air bubbles in wood boards, which comprises the following steps: after screening the wood boards containing air bubbles, drying the wood boards at low temperature, standing for cooling for later use; weighing the liquid medicine according to the proportion, mixing and preparing the liquid medicine, and using a sprayer to evenly spray the liquid medicine Spray on the front and back of the wooden boards, and place the wooden boards in layers and let them stand in a closed space; adjust the pressure in the closed space, let the wooden boards stand for a period of time, then turn over and spray again, continue to stand and adjust the pressure in the closed space, continue Stand still; after the standing is completed, put the wooden board in the pressing machine to pressurize and heat up at the same time, so that the liquid medicine and water vapor infiltrated into the wooden board are volatilized and the air bubbles inside the wooden board are pressed out; after the pressed wooden board is left to cool, Check to make sure that the repaired board is obtained after the air bubbles are eliminated. In the present invention, penetrating agent and alcohol go deep into the interior of the plate, and the internal moisture is heated up when pressurized to make it volatilize along with the alcohol, so as to achieve the effect of drying and removing bulges.

Description

technical field [0001] The invention relates to the technical field of board processing, in particular to a repair method for reducing air bubbles in a board. Background technique [0002] Wooden boards were originally solid wood boards for carpentry. They were used to make furniture or other living facilities. Nowadays, with the development of science and technology, the definition of boards is very broad. There are boards of different materials in furniture manufacturing, construction, and processing industries. Wooden board products have a flat shape, a large aspect ratio, and a large surface area per unit volume, and the wooden board can be cut and bent to make various product components, which is flexible and convenient to use. The process has certain requirements. Guangxi's wood production accounts for about 40% of the country's total, but because Guangxi is located in the south, there is a lot of rain and the air is humid, and the board itself is water-absorbent, so ...

Problems solved by technology

Guangxi's wood production accounts for about 40% of the country's total, but because Guangxi is located in the south, there is a lot of rain and the air is humid, and the board itself is water-absorbent, so the board itself will become damp; and most of the wood boards on the market now are glued. It is made by pressing, drying and other operations, but when drying, the water in the board will evaporate and the board will shrink to a certain extent, forming a hollow in the middle of the board. According to statistics, about 10% The hollowing rate caused serious waste and consumed a lot of resources. Some manufacturers recycled and reprocessed the boards. After sawing the boards, they were filled with glue and re-pressed. A way to solve the above problems
