应用羟乙基纤维素特别注意的六个难题

点击次数:194 发布日期:2021-09-08

应用羟乙基纤维素特别注意的六个难题:因为经表层处理的羟乙基纤维素是粉末状或纤维素固态,只需留意以下事宜,则非常容易实际操作并使之溶解溶水里。

1、尽量范畴内,提前添加除霉剂。

2、千万别在羟乙基纤维素粉末状被温度透前添加一些碱性物质于化合物中。在温透后才提升 PH值则有利于融解。

3、务必渐渐地筛入立式搅拌机内,切忌大量或把已结为小块和球形的羟乙基纤维素立即添加立式搅拌机内。

4、应用低粘度型号规格羟乙基纤维素时,水解液之浓度值不能高过2.5-3%,不然水解液难以实际操作。历经后处理工艺的羟乙基纤维素,一般不易产生小块或球形,亦不容易添加水时产生难溶球形胶体溶液。

5、在添加羟乙基纤维素前和后,均务必不断地拌和,直到水溶液彻底全透明回应截止。

6、温度和水里的PH值对羟乙基纤维素的融解有显著的关联必须需注意。
