近年来微孔滤膜的生产和应用发展得较快,在我国也是如此,但是对微孔滤膜的孔径指标,长期来一直含糊不清,从国外的产品说明书中也可发现不少微妙之处,为此提出一些看法供讨论指正。西德的Sartorius公司早在1927年即开始生产商品微孔滤膜,在第二次世界大战后,经美国Millipore公司的开发,使微孔滤膜有了很大发展,因而现在Millipore公司已成为生产微孔滤膜的权威,几乎所有生产微孔滤膜的工厂都有按该公司所订尺寸及孔径规格的产品,即使有不太合理处,也是依式照搬。
In recent years, the production and application of microporous membranes have developed rapidly. This is also true in China. However, the pore size index of microporous membranes has been ambiguous for a long time, and many subtleties can be found in foreign product specifications. For this purpose, some views are proposed for discussion and correction. The Sartorius company in West Germany started production of commercial microporous membranes as early as 1927. After World War II, it was developed by Millipore Corporation in the United States. The development of microporous membranes has been greatly advanced, and Millipore now becomes The authority of the production of microfiltration membranes, almost all factories producing microporous membranes have the size and pore size specifications of the company’s products, even if there is not reasonable, but also according to type.
