摘要： 以聚四氟乙烯乳液为涂层剂主要原料，采用泡沫涂层法对聚酰亚胺/聚四氟乙烯复合滤料进行表面涂层处理，研究了涂层对复合滤料的结构及性能的影响。结果表明，经涂层处理后，复合滤料表面形成一层致密多孔的聚四氟乙烯涂层，明显改善了复合滤料的热收缩性能，提高了滤料耐酸、耐碱性性能，改善了滤料表面过滤效果。
Abstract: Being main material of coating agent, the emulsion of PTFE was used to coat the surface of P84/PTFE compound filtering media by means of foam coating. The effect of coating on the structrue and properties of compound filtration medium was studied. The results indicated shat the compound filter after coating had better properties of heat shrinkage, acid resistance and alkali resistance, because of a dense porous coating of PTFE formed on the filter surface. Also filtration performance was improved obviously.
