Abstract

The invention discloses a vacuum impregnation method for preparing a high-tightness seal, which comprises the following steps: S1, adopting an impregnation tank with an inner cavity and a liftable tray in the inner cavity; S2, inserting an impregnation tank into the impregnation tank liquid, and keep the tray above the liquid level of the impregnating liquid; S3, place the seal to be impregnated on the tray, and then seal the sealing cover on the top of the dipping tank, so that a sealed cavity is formed between the dipping tank and the sealing cover ; S4, evacuating the sealing chamber; S5, lowering the tray, so that the entire sealing element is immersed in the immersion liquid. When the vacuum impregnation method of the present invention is used to impregnate the sealing member, the nanomaterials in the immersion liquid can fully penetrate into the microscopic pores of the flexible sealing material of the sealing member, so that the overall structure of the sealing member is denser and greatly improved. Improve the overall tightness of the seal, making it more effective and reliable when used in complex working conditions.

Description

technical field [0001] The invention relates to a vacuum impregnation method for preparing high-tightness seals. Background technique [0002] With the continuous increase of my country's industrialization process, environmental pollution is becoming more and more serious, and the country pays more and more attention to environmental protection. Volatile organic compounds produced in nuclear power, petrochemical and other fields will not only pollute the environment, but also endanger human health. Therefore, the country promulgated The standard stipulates the pollutant discharge limit value of petrochemical enterprises and their production facilities. One of the important ways to reduce VOC emissions is to improve the effectiveness of flange seals. [0003] Tests have proved that the tightness of the seal will directly affect its sealing effectiveness, and there is still a lack of seals that can improve the sealing effect by increasing the tightness of the seal. The appl...
