Product properties


1.     Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
 
2. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
 
3. Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
 
4. Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.

usage

 1. Appearance: white or off-white powder.
2, particle size; 100 mesh pass rate is greater than 98.5%; 80 mesh pass rate is 100%. The special size is 40~60 mesh.
3, carbonization temperature: 280-300 ° C

Hydroxypropyl methylcellulose sample
4. Apparent density: 0.25-0.70g/cm (usually around 0.5g/cm), specific gravity 1.26-1.31.
5, color change temperature: 190-200 ° C
6, surface tension: 2% aqueous solution is 42-56dyn / cm.
7, solubility properties: soluble in water and some solvents, such as the appropriate proportion of ethanol / water, propanol / water. The aqueous solution is surface active. The transparency is high and the performance is stable. The gel temperature varies with different specifications. The solubility changes with viscosity. The lower the viscosity, the greater the solubility. The performance of HPMC in different specifications is different. The dissolution of HPMC in water is not affected by pH.
8. HPMC decreases with the methoxy group content, the gel point increases, the water solubility decreases, and the surface activity also decreases.
9, HPMC also has thickening capacity, salt-tolerant low ash powder, pH stability, water retention, dimensional stability, excellent film formation, and a wide range of enzyme resistance, dispersibility and cohesive properties.
