Problems solved by technology

PVFM has excellent hydrophilic properties and can be used directly as a superabsorbent resin. It is directly used in oil and gas separation filter elements. Due to the preferential adsorption of water molecules, the effect of filtering oil droplets is not ideal.

Abstract

The invention discloses an air compressor oil-gas separation core material and its preparation process. The material has a sandwich composite structure of "surface hydrophobic and oleophobic + internal hydrophobic and oleophilic" through modification of polyvinyl formal foam; The preparation process is as follows: the polyvinyl formal foam body with internal hydrophobicity is prepared by modifying the surface active agent foaming method; and then the surface is subjected to fluorocarbon treatment to obtain the surface hydrophobicity and oleophobicity. The invention realizes the filtration selectivity of polyvinyl formal material to oil and water in compressed air, can efficiently separate oil droplets from high-humidity oily air, and has the advantages of high filtration efficiency, small pressure drop, high strength, long life, etc. Advantages, and the whole preparation process is simple, non-toxic and environmentally friendly, and low in cost.

Description

technical field [0001] The invention belongs to the field of gas filtration, and in particular relates to a filter material and a preparation method thereof. Background technique [0002] The oil-injected screw air compressor has many advantages such as low vibration, low noise, high efficiency, no wearing parts, and high reliability. It is the mainstream product of domestic and foreign air compressor brands. The air compressed from the main engine of the oil-injected compressor entrains oil droplets of different sizes, among which the larger oil droplets can be separated by centrifugal action, while the suspended small oil droplets must be filtered through the oil-gas separation filter element to be able to Get pure compressed air. [0003] At present, the oil and gas separation filter elements in the field of domestic air compressors are all made of disposable filter paper products made of various cotton and linen plant fibers, glass fibers, synthetic fibers, etc., mainly...
