聚乙烯塑料管(下简称塑料管)熔化点低,可塑性高,热合性能良好,在酒精灯上加热便可加工制成配制制剂需要的弯管、多通管、初滤管、套管等,代替玻璃管和橡皮管使用。加工制成的各种管可放入稀清洁液或75%酒精液中长期浸泡,并有抗压作用,适用于药液输送、抽空过滤、压滤、灌装、冲洗及离子交换器等管道装置。现将加工方法简述如下:1.弯管:取塑料管放在酒精灯火焰上,边加热边
Polyethylene plastic pipe (hereinafter referred to as plastic pipe) low melting point, high plasticity, good heat sealing performance can be processed into the preparation of alcohol in the heating lamp made of the required elbow, multi-tube, the first filter, casing, etc., Use instead of glass tube and rubber tube. Can be processed into a variety of tubes can be placed in lean cleaning solution or 75% alcohol solution in the long-term soaking, and a compressive effect, suitable for liquid delivery, vacuum filtration, pressure filtration, filling, washing and ion exchanger pipes Device. The processing method is briefly described as follows: 1 elbow: take the plastic tube on the alcohol lamp flame, while heating
