中文名称:尿失禁用吸尿助剂 聚丙烯酸酯高吸水粉 第3部分:用筛分选法测定粒径分布的试验方法
英文名称:Urine-absorbing aids for incontinence — Polyacrylate superabsorbent powders — Part 3: Test method for determination of the particle size distribution by sieve fractionation
发布日期:2020-10
标准范围
本文件规定了一种测量交联聚丙烯酸酯高吸水性粉末粒度分布的试验方法。它仅适用于使用筛子振动进行分离的测量。攻丝设备预计不会产生同样的效果。本方法适用于在规定试验条件下自由流动的粉末状聚合物高吸水性材料。
This document specifies a test method for measuring particle size distributions up to 850 μ of cross-linked polyacrylate superabsorbent powders. It applies only to measurements made where sieve shaking is used for the separation. Tapping equipment is not expected to deliver the same results.This method is applicable to powdered polymeric superabsorbent materials that are free-flowing under the specified test conditions.
