Embodiment

[0020] Vacuum pressure impregnation of wood is a fully loaded alternate processing method consisting of the following steps:

[0021] The devices required by the process include: cam mechanism; centrifugal pump; pressure impregnation tank; press; liquid medicine pool; vacuum pump; booster pump; suction and discharge valve; partial pressure pump; pressure gauge; vacuum gauge; circulating water tank;

[0022] The device is equipped with a circulating water tank, and the circulating water tank is fixedly connected with the centrifugal pump and the vacuum pump respectively. The vacuum pump is fixedly connected with the vacuum gauge and the pressure gauge successively. The suction and discharge valves are fixedly connected to the liquid medicine pool, and the pressure dipping tank is fixedly connected to the press; the press is located at the lower part of the device; the partial pressure pump is fixedly connected to the pressure dipping tank and the liquid medicine pool respectivel...

Abstract

The invention discloses a vacuum pressure impregnation full-load alternate machining method for wood. The method includes the steps that 1, multiple times of a full-load cell impregnation method are superposed; 2, after a planned time, the direction of a four-way valve is changed again, a modifier is pumped out through a circulating pump, vacuum is produced in an impregnation tank, and the step is repeated multiple times; and 3, the vacuum degree and the boosting pressure are main technological parameters affecting the treatment effect and efficiency, and selection of the parameters should be determined according to the properties of treated materials and the impregnation difficulty of the modifier. The method is actually generated by improving a vacuum pressure impregnation full-load machining method for the wood, the multiple times of the full-load cell impregnation methods are superposed to increase the maintenance dose and penetrance of the modifier in the wood, and the maximum modifier absorption amount and depth of penetration can be achieved. The method is suitable for the wood and wet wood difficult to impregnate.

Description

technical field [0001] The invention relates to a wood processing method, in particular to a wood vacuum pressure impregnation full-load alternate processing method. 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 ef...
