Example Embodiment
[0017] Such as figure 1 As shown, the specific embodiment of the present invention mainly includes the following steps: filling the solvent tank with dimethylacetamide, a solvent for soaking, and taking out the metal powder sintered filter element for viscose fiber spinning from the filter and putting it in the solvent tank for soaking 12-24h, the temperature is controlled at 90 ℃, so that the surface of the filter element and the viscose in the pores are fully dissolved, and soaked and dried naturally. Put the filter element into a heating furnace, slowly raise the temperature from 100 to 350°C, control the baking time to 2 to 4 hours, remove organic dirt, carbonize the polymer in the micropores, and take it out after cooling. Put the filter element into a 5-15% sodium hydroxide solution lye tank, boil it, soak in lye for 2 to 4 hours. Take out the filter element from the lye tank, use a high-pressure water gun to rinse the filter element from the outside to the inside, and f...
