Product Description
CMC and PAC are both cellulose derivatives with an ether structure formed by chemical modification of cellulose. Both have properties such as thickening, water retention, bonding, suspension stability, emulsification and dispersion, and protective st

Instructions
First make PAC into a 2~3% aqueous solution with water, and then add it to the system. When using instant PAC, the instant PAC should be dispersed in water, and ammonia or naoh should be added to adjust the pH to about 9 for rapid dissolution. The amount of PAC added: 0.2~0.5% of the system.
2. Application of CMC in mortar
Adding CMC to the mortar can increase the water retention of the mortar without affecting its compressive strength. Just adding 0.5-1% of cement can reduce the water absorption by more than 30%. This kind of mortar can be used on aerated concrete masonry. Preventing hollowing, cracking or even falling off will enable this green and energy-saving aerated concrete to be widely promoted and used. Choose model CMC-m6, m3, h10.
3. Application of CMC in concrete
Choose model CMC-cd, m6, m3, h10. Adding amount accounts for 0.1-0.3% of water
A. As a retarder: Adding CMC to concrete has obvious water retention effect, prolongs the setting time of concrete, improves the initial strength of concrete, and avoids cracks in buildings.
B. Used as a pumping agent: used to keep the concrete mixture from bleeding or segregating, and to improve the homogeneity of the concrete.
4. CMC modified glue for wallpaper
Modified 107 glue: 40 kg CMC-h10 (2.5%): 12 kg Water: 20 kg
Adding CMC can improve bonding strength and reduce costs.
5. Application of CMC in gypsum products
CMC is used for painting gypsum, bonding gypsum, and gypsum putty, which can significantly improve its water retention and bonding strength.
Choose model CMC-m6, m3, and add 0.1-0.3%.
6. Applications in oil and gas drilling, well digging and other engineering fields
Drilling fluid and completion fluid technology is an important part of petroleum drilling engineering. It plays a key role in ensuring safe, high-quality and fast drilling. As a type of treatment agent used to adjust the performance of well fluid and completion fluid, The main functions of cellulose are in reducing filter loss and increasing viscosity.
It is generally believed that the main mechanism of filter loss reduction of polyanionic cellulose is: improving the coalescence stability of the system by forming an adsorption solvation layer on the surface of drilling clay soil particles, preventing the growth of clay fine particle agglomerates through the protection of clay fine particles, Reduce the permeability of the mud cake by increasing the viscosity of the filtrate and blocking the pores
