One of the biggest differences between dry mix mortar and traditional mortar is the modification of dry mix mortar with a small amount of chemical additives. Adding one additive to dry mortar is called primary modification, and adding two or more additives is secondary modification. The quality of dry powder mortar depends on the correct […]
Read MoreWater retention of cellulose ether: In the production of building materials, especially dry powder mortar, cellulose ether plays an irreplaceable role, especially in the production of special mortar (modified mortar), it is an indispensable and important part . The important role of water-soluble cellulose ether in mortar is mainly in three aspects, one is excellent […]
