1.Appearance: white or white powder, odorless and tasteless.
2.Granularity: the 100 mesh pass rate is greater than 98.5%; The 80 mesh pass rate was more than 100%.
3.Carbonization temperature: 280-300℃.
4.Apparent density: 0.25-0.70g/ m2 (usually about 0.5g/ m2), specific gravity: 1.26-1.31.
5.Color changing temperature: 190-200℃.
6.Surface tension: 20% aqueous solution is 42-56dyn/cm.
7.With the decrease of methoxide content, the gel point increased, the water solubility decreased, and the surface activity decreased.
8.Solubility: soluble in water and some organic solvents, such as appropriate proportion of ethanol/water, propanol/water, dichloroethane, etc. Water soluble the liquid has surface activity, high transparency and stable performance. Different specifications of the product gel temperature is different, this is the HPMC thermal gel properties. The solubility varies with the viscosity. The lower the viscosity, the greater the solubility. The performance of HPMC of different specifications varies to some extent.
9.HPMC also has thickening ability, salt exclusion, low ash content, PH stability, water retention, dimensional stability, excellent film formation and extensive enzyme resistance, dispersion and bonding.
Chemical name and structure formula
Advantages of HPMC in building materials field
1.Improve lubricity and plasticity so as to enhance machinability and make product construction more convenient and quick.
2.Enhance water retention characteristics, extend the working time.
3.Helps prevent vertical flow of mortar, mortar and ceramic tiles. Lengthen cooling time and Improve work efficiency.
4.Improve the bonding strength of ceramic tile adhesive.
5.Enhance the crack shrinkage and crack resistance of mortar and plate seam filler.
6.Improve the air content of mortar, greatly reduce the possibility of cracks.
7. Can enhance ceramic tile adhesive resistance vertical flow.
8.Use with starch ether, better effect
1.Mix well with dry powder.
2.With the characteristics of cold water dispersion.
3.Make the solid particles effectively suspended, make the mixture more fine and uniform.
1.Containing cellulose ether dry mix formula can be easily mixed with water.
2.Get the desired consistency quickly.
3.Cellulose ether dissolves more quickly and without clumps.
