Mixed cementitious mortars have become a very important part of the mortar industry in Global and play anindispensable role due to the market promotion and national support of policy. In development of mortars, cellulose ether is animportant activist. Ordinary mortar is economically demanding in which cement level is small, but the requirements for its operating and machine spraying properties are still high, so sand grading and additives are important. In addition, mechanical application will become a definite tendency of development of ready-mixed mortar, cellulose ether will make mechanical application possible. Product Features Increase water demand. High water retention, prolong the operating time of the material, improve the working performance, avoid the phenomenon of crusting, and help to improve the mechanical strength of the material. Improved operating performance, provide lubrication and uniform texture, so that the surface of the material is easier to wipe, thus improving the construction efficiency, and improve the resistance to cracking of putty. Improve homogeneity, and improve vertical flow resistance. HPMC for tile adhesive Ceramic tiles have high performance and excellent work efficiency when pasted on various substrates. Skid resistance and better opening time are the key to better adhesive requirements. HPMC for wall putty HPMC is non-ionic cellulose ether made from natural cotton fiber under series of chemical processing. It’s odorless, tasteless and non-toxic white powder, can be dissolved in normal water to form a transparent viscous solution with the properties of thickening,binding, dispersing, emulsifying, film coating, suspending, absorbing, gelling, water retention and colloid protection. cellulose ethers impart the following excellent properties to mortar: 一Optimized wetting ability to the substrate 一 Advanced water retention ability 一 good spraying and pumping performance 一 Improve cement hydration by bonding strength Product Description 1) Appearance: HPMC is a nonionic cellulose ether, white grayish-white powder or granule,odorless and flavorless, soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending on the degree of substitutions, practically insoluble in hot water, ethylene glycol and toluene. HPMC is dissolved in a mixture of 10% methanol and 90% methylene chloride to form colloidal solutions. 2) The solution of HPMC has surface activity, high transparency, and stable performance. When heated at certain temperature, the solution becomes cloudy or forms flocculent gel. However, the solution becomes clear again after cooling. Different types of HPMC have different gelation temperatures. The solubility varies with the viscosity. The lower the viscosity, the higher solubility it has. The different types of HPMC are different in some properties and their solubility in water is not affected by pH. 3) Particle sizes: 100% pass rate in 80 mesh. 4) Apparent density: 0.25-0.70 g/mL (usually about 0.5 g/mL),specific density 1.26-1.31mL. 5) Color change temperature:190-200°C; Carbonization temperature:280-300°C. 6) Surface tension:42-56 dyn/cm (2% aqueous solution). 7) The higher methoxy content in HPMC, the lower gelation temperature, and the higher solubility in water and surface activity. 8) HPMC has some other characteristics, for example, thickening property, pH stability, retention of water, excellent film-forming property, good disperse and adhesion ability.

Printing and dyeing grade CMC model: YT15 CMC has been widely used in printing and dyeing. Compared with sodium alginate, CMC has a high cost performance ratio. It can replace the application of sodium alginate in the field of textile printing and dyeing, so that you can use it better and save costs CMC-Application In Printing And Dyeing Printing and dyeing grade CMC has the following characteristics: 1. Super high degree of substitution and uniform distribution of substituents; 2. Stable viscosity, excellent salt and alkali resistance, and good dilution resistance. 3. The filtration and fluidity of the solution are excellent; 4. Excellent coloring; 5. After printing and dyeing, the washing efficiency is high, the fabric feels good, and the softness is equivalent to that of sodium alginate; 6. It has good water holding property and can print fine patterns; 7. very few gel particles, printing and dyeing will not be defective； 8.
