涤纶膜一般不易洗净,除因其有静电吸附性外,还因有很强的抗水性。这种抗水性使蒸馏水不能润湿涤纶膜,因而涤纶膜上的静电不易被中和,杂质也就较难洗脱。离子型表面活性刑具有润湿作用,能降低水与涤纶膜的界面张力,并因离子化而中和静电荷。实验表明,0.05%的十二烷基硫酸钠水溶液能较好地润湿涤纶膜,明显提高杂质的洗脱效果,特介绍如下: 将涤纶膜逐张捻开,浸泡于含0.1%十二烷基硫
Polyester film is generally not easy to wash, except because of its electrostatic adsorption, but also because of strong water resistance. This water resistance so that distilled water can not wet polyester film, polyester film on the static electricity is not easy to be neutralized, impurities will be more difficult to elute. Ionic surfactants have a wetting effect, reducing the interfacial tension between water and the polyester film and neutralizing the electrostatic charge due to ionization. Experiments show that 0.05% sodium dodecyl sulfate aqueous solution can better wet polyester film, significantly improve the elution of impurities, especially introduced as follows: The polyester film twist twist open, soaked in 0.1% dodecane Sulfur base
