采用3～5％NaOH液浸泡处理涤纶薄膜是我们近两年来使用的一种新方法。它具有以下几个特点:①能除去薄膜表面上的附着物及其自身产生的静电引力。NaOH是一种强电解质,有正负两种电荷,这些附着物,灰尘、纤维等物质多以正负离子间的吸引而附着于薄膜表面的大磁场上。当其在水中与NaOH液接触和洗涤下,电荷间的引力发生改变,至使薄膜表面上的附着物被其更大的磁场NaOH液中强电解质所吸引、结合而被同时洗脱。分子间的引力发生改变,静电引力被破坏。②能破坏和杀死由于薄膜受污染所带来的细菌和热原。热原和细菌均能被强酸强碱所破坏,因此它能杀死细菌和破坏热原的产生。③处理方法简单,洁净度高,不受任何液体药物的影响。NaOH是一种强
The use of 3 ~ 5% NaOH solution soaked polyester film processing is our last two years to use a new method. It has the following characteristics: ① can remove the attachment of the film surface and its own electrostatic attraction. NaOH is a strong electrolyte, there are positive and negative charges, these attachments, dust, fibers and other substances are more positive and negative ions in the attraction and attached to the membrane surface of the large magnetic field. When it is contacted with NaOH solution in water and washed, the gravitational force between the charges changes so that the attachment on the film surface is attracted by the stronger electrolyte in its larger magnetic field NaOH solution, and simultaneously eluted. Intermolecular gravity changes, electrostatic attraction is destroyed. ② can destroy and kill bacteria and pyrogens due to contamination of the film. Both pyrogen and bacteria can be destroyed by strong acid and alkali, so it can kill bacteria and destroy the production of pyrogen. ③ treatment is simple, clean, high, free from any liquid drugs. NaOH is a strong one
