3 Terms and definitions

GB/T.20103 and the following terms and definitions are applicable to this standard. 3.1 The outer shape is a fibrous, hollow polypropylene microporous membrane with a supporting function, and the inner and outer walls of the polypropylene microporous membrane with a through grid-like narrow and long hole structure. Note 1.Polypropylene hollow fiber microporous membrane is different from flat microporous membrane, it is a typical product of hollow fiber microporous membrane prepared by melt spinning stretching method. Note 2.Rewrite GB/T.20103-2006 and define 2.1.28. 3.2 The diameter of a circular capillary equivalent to the largest pore of the microporous membrane. [GB/T.20103-2006, definition 5.1.5] 3.3 The arithmetic average of the outer diameter and inner diameter of the membrane fiber. 3.4 The percentage of membrane pore volume to the entire membrane volume. [GB/T.20103-2006, definition 5.1.5] 3.5 According to the specified temperature and pressure, the total volume of nitrogen passing through a unit membrane area in a unit time. Note 1.The test gas can completely permeate the polypropylene hollow fiber microporous membrane, which is not a permeation separation process, so flux is used instead of permeability. Note 2.Rewrite GB/T.20103-2006 and define 6.1.3. HY/T 110-2008
