涤纶针刺滤料的拒水拒油整理工艺研究

摘要

使用FG-910含氟拒水拒油整理剂对涤纶针刺滤料进行拒水拒油整理,研究了在整理过程中五个主要因素对整理效果的影响规律,并进行了正交优化试验. 结果表明:最佳的整理工艺参数是浸渍温度55 ℃、浸渍时间25 min、FG-910质量浓度60 g/L、焙烘温度150 ℃和焙烘时间150 s,在该条件下整理可使涤纶针刺滤料的拒水等级和拒油等级都达到8级,且透气率变化率达到18.75%,可有效地改善滤料的过滤性能.%Used fluorinated reagent FG-910 to do water an filter material , the influence of five major factors on the finishing effects was studied , and then did orthogonal optimization test .The results showed that the optimum finishing process as follows:dipping temperature was 55 ℃, dipping time was 25 min, FG-910 concentration was 60 g/L, curing tempera-ture was 150 ℃and curing time was 150 s.Under this condition water-repellency and oil-repellency grade of polyester needle punched filter material has reached eight , and the permeability has reached 18.75%, which improved the filtration performance of filter media effectively . d oil repellent finishing for polyester needle punched
