Abstract

The invention discloses a polyamide filter material. The filter material adopts a hollow cylindrical structure produced through melt-blowing process treatment of a polyamide material and adhesion and winding of blown superfine fibers; the filter material adopts a loose structure and filter holes with different hole diameters are formed; the hole diameters of the filter holes sequentially and gradually decrease from the outer layer of the cylindrical structure to the inner layer. The characteristic that the polyamide material is resistant to corrosion by multiple chemical raw materials is used, melt-blowing process treatment is performed, the structure identical with that of a common polypropylene filter element is obtained, on the premise that oil and alcohol corrosion resistance of the material is guaranteed, the filter material has better filter precision, pollutant-holding capacity and circulation drag parameters, and the filter requirement of oils, chemical waste liquor and chemical waste gas is met.

Description

technical field [0001] The invention relates to a filter material, a preparation device and a preparation method thereof, in particular to a polyamide filter material used for filtering oil products, chemical waste gas and waste liquid and a preparation method thereof. Background technique [0002] During the production, transportation and storage of engine fuel, a large number of impurities will be produced and mixed. Clean fuel oil will also produce pollutants such as metal oxides, precipitated colloids, and asphaltene after storage for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine's fuel injection system and combustion chamber, resulting in increased fuel consumption and a sharp increase in exhaust emissions after the fuel engine has been used for a period of time. The current common solution is to install an oil filter on the engine to remove impurities, colloids, asphaltene and moisture in the fuel. Clean fuel can improve c...
