羧甲基纤维素(HPMC),是纤维素的羧甲基团取代产物。根据其分子量或取代程度,可以是完全溶解的或不可溶的多聚体,后者可作为弱酸型阳离子交换剂,用以分离中性或碱性蛋白质等。羧甲基纤维素可形成高粘度的胶体、溶液、有粘着、增稠、流动、乳化分散、赋形、保水、保护胶体、薄膜成型、耐酸、耐盐、悬浊等特性,且生理无害,因此在食品、医药、日化、石油、造纸、纺织、建筑等领域生产中得到广泛应用。
Carboxymethyl cellulose (HPMC), is a cellulose carboxymethyl group substituted products. According to their molecular weight or degree of substitution, can be completely soluble or insoluble polymer, which can be used as a weak acid cation exchange agent, for the separation of neutral or alkaline protein. Carboxymethyl cellulose can form colloidal solution, high viscosity, adhesion, thickening, emulsifying, flow, shaped, water retention, protective colloid, film forming, acid resistance, salt tolerance, suspension and other characteristics, and the physiological harm, so it has been widely used in food, medicine, daily chemical, petroleum, papermaking, textile, construction and other fields in production.

羟丙基甲基纤维素主要有三种溶解方法,分别是热水法、粉末混合法、有机溶剂湿润法。在其中热水法是比较容易的,hpmc一般是不在热水中溶解的,初期的时候只会在热水中分散,之后冷却。先在容器中放入适当的热水,加热到70摄氏度之后,再慢慢地搅拌,加入羟丙基甲基纤维素,它就会浮到水面上,然后形成一种淤浆。
Hydroxypropyl methyl cellulose mainly have three kinds of dissolution method, respectively is the hot water method, powder mixing method, organic solvent, wetting method. In the hot water method is relatively easy, HPMC is generally not dissolve in hot water, early will only dispersed in hot water, after cooling. To add the appropriate water in a container, heated to 70 degrees Celsius, then slowly stirring, adding hydroxypropyl methyl cellulose, it will float to the surface, and then forming a slurry.

另外,也可以在容器中加入三分之一或者是二的水,加热到70摄氏度,分散羟丙基甲基纤维素,制备热水淤浆,然后把剩下的冷水加进去,搅拌之后冷却。
In addition, also can add 1/3 in the container or is two water, heated to 70 degrees Celsius, dispersible hydroxypropyl methyl cellulose, preparation water slurry, and then the rest of the cold water added, stirring after cooling.

这就是羟丙基甲基纤维素的主要溶解办法,它的使用范围是很广泛的,受到了很多行业的欢迎,相信大家现在对它有了更进一层的了解了吧。
This is the main solution of hydroxypropyl methyl cellulose solution, its use scope is very broad, subject to a lot of industry welcome, I believe we now have more into a layer of understanding.
