PROPERTIES OF HPMC for Drymix Mortar:
* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
* Charring temperature: 280-300β.
* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
* Real specific gravity: 1.26-1.31.
* Browning temperature: 190-200β.
* Surface tension: (2% water solution) 42-56dyn.cm.
* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.
Construction grade Hydroxyporpyl Methyl Cellulose(HPMC)
It is widely used in drymix mortar industry. Could be soluble in water and form the transparent solution. As the important additives in mortar, Hydroxyproypl methyl Cellulose could increase the water retention, increase the workability and increase open time etc.
