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 -
