What is the main use of hydroxypropyl methylcellulose?
HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into industrial grade, food grade and pharmaceutical grade according to the application. 2Hydroxypropyl methylce...Read more -
Production process and flow of HPMC
Refined cotton—opening—alkalization—etherification—neutralization—separation—washing—separation—drying—crushing—packaging—finished product opening: The refined cotton is opened to remove iron and then crushed. The pulverized refined cotton is in the form of powder, with a particle size of 80 mesh...Read more -
Common problems and solutions in the use of interior wall putty powder
1 Common problems in putty powder: (1) Dries fast. This is mainly because the amount of ash calcium powder added (too large, the amount of ash calcium powder used in the putty formula can be appropriately reduced) is related to the water retention rate of the fiber, and it is also related to the ...Read more -
Properties of hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose is a kind of non-ionic cellulose mixed ether. Unlike ionic methyl carboxymethyl cellulose mixed ether, it does not react with heavy metals. Due to the different ratios of methoxyl content and hydroxypropyl content in hydroxypropyl methylcellulose and different viscos...Read more -
carboxymethyl cellulose
Natural cellulose is the most widely distributed and most abundant polysaccharide in nature, and its sources are very rich. The current modification technology of cellulose mainly focuses on etherification and esterification. Carboxymethylation reaction is a kind of etherification technology. Car...Read more -
Viscosity is an important parameter of cellulose ether performance
Generally speaking, the higher the viscosity, the better the water retention effect of gypsum mortar. However, the higher the viscosity, the higher the molecular weight of cellulose ether, and the corresponding decrease in its solubility will have a negative impact on the strength and constructio...Read more -
What role does cellulose ether play in dry-mix mortar?
Cellulose ether is a type of chemical additive commonly used in building materials, especially in dry-mix mortar. Dry-mix mortar is a mortar with various ingredients pre-mixed, which can be used by adding an appropriate amount of water during construction. The addition of cellulose ether is mainl...Read more -
The role of cellulose ether in dry powder mortar
Cellulose ether is a synthetic polymer made from natural cellulose through chemical modification. Cellulose ether is a derivative of natural cellulose.
