Deep analysis of the temperature of hydroxypropyl methyl cellulose gel in Shandong Chuang Yao Biotechnology

1.many users seldom pay attention to the problem of hydroxypropyl methyl cellulose > hydroxypropyl methyl cellulose gel temperature. Nowadays, generally speaking, hydroxypropyl methyl cellulose is distinguished according to viscosity. But for some special environments and special industries, the viscosity of products is not enough. Here is a brief introduction of the temperature of hydroxypropyl methyl cellulose gel.

2.The content of methoxy group is directly related to the etherification degree of cellulose ether. The content of methoxy group can be adjusted by controlling the formula, reaction temperature and reaction time. At the same time, the degree of etherification affects the degree of substitution of hydroxyethyl or hydroxypropyl. Therefore, generally, the high gel temperature of cellulose ether water retention will be a little worse. This production process needs to be explored, so the price of cellulose ether is not low if the methoxy content is low. On the contrary, the price will be higher.

3.The temperature of hydroxypropyl methyl cellulose gel is determined by methoxy, and the water holding capacity is determined by hydroxypropyl. There are only three replaceable groups on cellulose. Find out your appropriate temperature and water retention, and then determine the type of cellulose.

4.The temperature of hydroxypropyl methyl cellulose gel is a critical point in the application of cellulose ether. When the ambient temperature exceeds the gel temperature, the cellulose ether will precipitate from water and lose its water retention. The cellulose ether gel temperature in the market can basically meet the needs of mortar environment (except the environment). Personally, it is not necessary to pay special attention to the performance index of gel temperature when mortar is applied. Of course, manufacturers engaged in the production of cellulose ether must consider it.
