When using a dry powder mortar production line, it is necessary to use dry powder mortar. How to solve the problem of insufficient viscosity when using dry powder mortar? As a large-scale dry powder mortar production line manufacturer, let me take you to learn specifically!
first. Adding water must be done in moderation, just like making noodles at home. If there is too much water and too little water, the result will be different
The HPMC in dry powder mortar has an impact on the viscosity and consistency of the mortar in the early stage
Adding PVA in moderation can increase the viscosity of mortar.
4. Excessive temperature of sand and poor water retention of cellulose can also lead to poor viscosity. Viscosity selection: It is not recommended to use high viscosity cellulose ether for masonry plastering mortar, as it involves joint filling and is difficult to construct. The requirement for water retention rate of masonry mortar is not high, and generally 40000 to 80000 medium viscosity cellulose ether is used.
5. Not adding K12 (foaming agent), inappropriate dosage, unstable quality, etc.
6. Improper use of air entraining agent. Generally, a small amount of air entraining agent mixed with bentonite is used to improve construction performance. However, adding 1% more bentonite results in high water retention and stickiness.
