| titleOfInvention | A kind of durable hydrophilic modified polyethylene filter element and preparation method thereof |
| abstract | The invention discloses a durable hydrophilic modified polyethylene filter element and a preparation method thereof. The method comprises the following steps: dissolving a hydrophilic monomer, a crosslinking agent and an initiator in a solvent, and mixing them uniformly to obtain a modified polyethylene filter element. solution; the polyethylene powder is wetted with the modified solution and then pressed into the filter element mold, and the hydrophilic monomer chemical cross-linking reaction is carried out in the filter element mold, and then sintered to obtain a durable hydrophilic modified polyethylene powder. vinyl filter products. In the present invention, the cross-linked polyethylene powder particles are coated with a hydrophilic monomer, and the sintered polyethylene filter element is prepared to obtain a durable hydrophilized polyethylene filter element. The polyethylene filter element prepared by the method is chemically cross-linked due to the coating of the hydrophilic monomer on the surface of the polyethylene powder particles, so the hydrophilicity can remain unchanged after long-term operation, thereby significantly reducing the operating pressure and improving the pollution degree. Improve operational efficiency. |
