Abstract

The invention discloses a vacuum pressure impregnating full-load processing method for wood. The vacuum pressure impregnating full-load processing method for the wood has the following steps of (1) conducting a pre-vacuum period, specifically, placing the wood in a pressure impregnating tank and then vacuumizing the pressure impregnating tank through a vacuum pump; (2) adding modifying agents, specifically, under the condition that the vacuum pump is not closed, that is, under the condition that the original vacuum degree is kept, adding the modifying agent solution; (3) conducting pressurization; (4) discharging the modifying agent solution; and (5) achieving post-vacuum. According to the vacuum pressure impregnating full-load processing method for the wood, cells of the wood are filled with the modifying agent solution and the maximum quantity of modifying agents are kept in the wood. The method is strict in condition so that the maximized modifying agent chemical sucking amount and the maximized penetration depth can be achieved.

Description

technical field [0001] The invention relates to a wood processing method, in particular to a full-load processing method of wood vacuum pressure impregnation. Background technique [0002] At present, wood as a natural material has many advantages, but there are also many shortcomings, especially in wood processing, industrial plantation wood, which is one of the main raw materials, has more defects that need to be overcome. At the same time, with the improvement of people's living standards, the quality requirements for wood materials are gradually increasing. In order to make the wood more in line with the needs of the customer's life, the wood must be modified. Wood modification or wood function improvement is one of the important fields in the wood processing industry. The purpose is to further strengthen the advantages of materials and improve the shortcomings of materials to varying degrees through physical and chemical treatments, thereby enhancing Its use effect an...
