The effect of adding cellulose to putty powder
When we use putty powder, there will often be some problems, so we don’t know the reason. I think there should be seven kinds of problems that often appear in putty powder! ? One: Do it fast. This is mainly related to the addition of ash calcium and the water retention rate of the fiber, an...Read more -
The use of hydroxypropyl methylcellulose, how to distinguish the quality of HPMC simply and intuitively
What is the main use of hydroxypropyl methylcellulose? ——Answer: 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 construction grade, food grade and pharmac...Read more -
What is the reason for the unstable setting time of dry-mixed mortar?
The setting time of dry-mixed mortar in the national standard is 3-8 hours, but the setting time of many dry-mixed mortars is unstable. Some mortars set for a long time and do not solidify for a long time. But it is prone to cracking in the later stage. So why is dry-mixed mortar prone to unstabl...Read more -
What is the relationship between the ash content of hydroxypropyl methylcellulose and the quality of cellulose?
First of all, we need to know what is ash? When burning at high temperature, hydroxypropyl methylcellulose undergoes a series of physical and chemical changes, and finally the organic components volatilize and escape, while the inorganic components (mainly inorganic salts and oxides) remain, and ...Read more -
Dissolving method and determination method of hydroxypropyl methylcellulose HPMC
test methods Method name: hypromellose—determination of hydroxypropoxy group—determination of hydroxypropoxy group Scope of application: This method uses the hydroxypropoxy determination method to determine the content of hydroxypropoxy in hypromellose. This method is applicable to hy...Read more -
