Overview |
Description |
Methyl hydroxyethyl cellulose (HEMC) is a multi-group ether mixed with methoxy and hydroxyethoxy. Compared with hydroxypropoxy, the biggest feature of hydroxyethoxy is that it does not change with temperature. Gel spots appear. HEMC has a gel point, but it is relatively high, and as the content of hydroxyethoxy group increases, its gel point moves to the direction of high temperature. If it is used in mixed mortar, it is beneficial to delay the electrochemical reaction of cement paste at high temperature. , Improve the water retention rate and tensile bond strength of the system. HEMC is also used in food, coatings, medical dressings and other fields, and also shows superior performance. |
