标准范围

本文件提供了一种评估交联聚丙烯酸酯高吸水性粉末加热时质量损失的试验方法。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。在此温度范围内易挥发的物质（水除外）会产生干扰。聚合物配方制定者/生产商有责任决定是否可能存在此类干扰，或者将该方法排除在使用之外，提供替代方法，或者相应地修改该方法。

This document provides a test method for the evaluation of mass loss upon heating for cross-linked polyacrylate superabsorbent powders.This method is applicable to powdered polymeric superabsorbent materials that are free-flowing under the specified test conditions. Substances other than water that are volatile in this temperature range will interfere. The onus is on the polymer formulator/producer to decide if such interference is possible and either exclude the method from use, provide an alternative or modify the method accordingly.
