Viscosity of cellulose ether in different scenarios（1）
(3) Concrete mortars
In concrete mortars, the final strength is really achieved only if the cement is completely hydrated. Especially in the summer construction, concrete mortar water loss is too fast, take the measure of complete hydration on the maintenance of water spreading. This method, for one thing, results in wasted water and operational inconvenience. The key is that the water is only on the surface, while the internal hydration is still incomplete. So the solution to this problem is to add a water retaining agent, cellulose, to the mortar concrete. Generally choose hydroxypropyl methyl or methyl cellulose, viscosity specifications between 20000 – 60000cps, add 2% – 3%. or so. Water retention rate can be increased to 85% or more, the use of mortar concrete in the method of dry powder evenly mixed with the addition of water can be.
(4) Insulation mortar
Insulation mortar is a new type of internal wall insulation material in the northern region, it is a wall material synthesized by insulation material, mortar and binder. Cellulose in this material, focus on the role of bonding, increase strength. Generally choose methyl cellulose high viscosity (10000 eps or so), the dosage is generally between 2‰-3‰), the use method for dry powder mixing method.
(5) Interface agent
Interface agent choose HPNC20000cps, tile binder choose 60000cps above. In the interface agent focus on thickening agent, can improve the tensile strength and arrow strength and other effects. In the tile bonding as a water retention agent, to prevent the tiles from losing water too quickly off, etc.
