Addition Of Hydroxypropyl Methyl Cellulose

Add the amount of hpmc no specific standards, according to the different needs of different dosage of mortar, plaster, mortar bonding, such as general quantity is 2~2.5 kg per ton, putty quantity is 3~4.5, tile adhesive sealant between 3.5~4, according to the different construction methods and slot width, pulp in addition, the fineness of body 0.3~1kgt, self leveling mortar between 0.2~0.6 inorganic lightweight insulation mortar in between 4~7. The above proportion should be adjusted according to hpmc's own water retention and viscosity. Besides, it should be adjusted according to the construction season, climate, air dry degree and the specific conditions of the wall base. Hpmc can be said to be a most important mortar additive, directly affect the construction, water retention and mortar viscosity and eventually feel intuitive to use water retention effect of cement hydration of mortar strength, is not a simple sentence can be said to understand the content, concrete is also according to deal with the current situation. Specific circumstances. Cement based render(plastermortar) is themixture of suitable sand, cement and water which is generally applied tomasonry interiors and exterior to smooth wall surface. Yicheng hpmc plays akey role in cement based render(plastermortar) to achieve the excellentperformance of water retention, open time, workability, crack resistance, sagresistance, etc. Hpmc for cement based renderplastermortar, good water retention.
