HPMC For Drymix Mortar

It is widely used in drymix mortar industry. Could be soluble in water and
form the transparent solution. As the important additives in mortar, HaoShuo
Hydroxyproypl methyl Cellulose could increase the water retention, increase
the workability and increase open time etc.
Construction Grade Hpmc PHYSICAL AND CHEMICAL PROPERTIES:
* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
* Charring temperature: 280-300℃.
* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
* Real specific gravity: 1.26-1.31.
* Browning temperature: 190-200℃.
* 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 China Hydroxypropyl
Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will
form gelation at 60%.
