Hydroxypropyl Methyl Cellulose (HPMC) Used for Cement base plaster

Cement based plaster/render is the finishing material that can be applied to any interior or exterior walls.It is applied to interior or exterior walls such as block wall, concrete wall, ALC block wall etc. Either manually (hand plaster) or by spray machines.

A good mortar should have good workability, smear smooth non-stick knife, enough operating time, easy leveling; In today’s mechanized construction, mortar should also have good pumping, to avoid the possibility of mortar layering and pipe blocking. Mortar hardening body should have excellent strength performance and surface appearance, appropriate compressive strength, good durability, no hollow, no cracking.

Our cellulose ether water retention performance to reduce the absorption of water by the hollow substrate, promote the gel material better hydration, in a large area of construction, can greatly reduce the probability of early mortar drying cracking, improve bond strength; Its thickening ability can improve the wetting ability of wet mortar to the base surface.

Cement plaster application advanatges and improve function

Provides lubricity
We gives the modified mortar its lubricity. This lubrication effect reduces the friction and thus reduces the extrusion temperature, which in turn reduces the water evaporation, better allowing the extruded element to complete the hydration process.

Reduces tool wear
In addition to lowering the inter-particle friction force,we also lowers the friction and abrasive force against the extrusion tools, leading to less tool wear, prolonging its useful life, some times even doubl ing the useful life, thus reducing one major cost.

Increases water demand
Unmodified true zero-slump extrusion mix contains very l ittle extra water needed for hydration to complete. When a portion of this water is evaporated due to heat produced during extrusion process, hydration cannot complete properly. We can provide the zero-slump even at elevated water levels, without sacrificing strength, which normal ly happens with a higher water:cement ratio, thus al lowing the hydration to actually complete.

Improves water retention
The compression force and friction force tend to heat up the extrusion mix and cause water to evaporate, leaving little water for hydration to occur. We can retain the water effectively even at elevated temperature to allow hydration to complete.

Provides excellent strength
We can give the freshly extruded material excellent green strength, so that they can be handled and moved without much worry of slumping or shape loss.
