因涤纶薄膜具有静电吸附性,具较大的抗水性,不易被水湿润,故其表面杂质较准洗脱。离子型表面活性剂具有中和电荷、降低水和涤纶薄膜界面张力的作用,使涤纶薄膜吸附空气中纤维和尘埃容易洗脱;从而提高大输液的澄明度。本文就静电消除的原理和方法做初步的探讨。静电消除原理抗静电剂是一表面活性剂,由亲水和亲油两个基团构成,它主要能使涤纶薄膜表面吸收水份形成水膜,涤纶薄膜表面不可能是非常纯净的;这种水膜必然含有相当数量杂质、离子,使聚合物表面电阻率大大降低,因而防止电荷积累。实验表明0.2～0.5％新洁尔灭能消除静电并能较好湿润涤纶薄膜;明显提高洗脱效果。操作方法: 将涤纶薄膜逐张散开后,用0.2—0.5％新洁尔灭溶液浸24h,倾出新洁尔液,用蒸馏水漂洗数次,置
Due to electrostatic adsorption of polyester film, with greater resistance to water, not easily wet with water, so the more accurate elution of impurities on the surface. Ionic surfactants have the effect of neutralizing the charge and reducing the interfacial tension between water and polyester film, so that the fibers and dust in the air can be easily eluted by the polyester film, thereby improving the clarity of large infusion. In this paper, static elimination principle and method to do a preliminary discussion. Static elimination principle Antistatic agent is a surfactant, composed of two groups of hydrophilic and lipophilic, it can mainly make the surface of the polyester film absorb water to form a water film, polyester film surface can not be very pure; this water The membrane necessarily contains a considerable amount of impurities, ions, so that the polymer surface resistivity is greatly reduced, thus preventing the charge accumulation. Experiments show that 0.2 to 0.5% benzalkonium bromide can eliminate static electricity and better moist polyester film; significantly improve the elution effect. Method of operation: After the polyester film is opened one by one, with 0.2-0.5% Bromogeramine solution immersed 24h, pour out the new Jie Seoul solution, rinsed with distilled water several times, set
