What is the role of dry powder mortar in coating production? Below, the paint production line manufacturer will introduce it to you.
Dry powder mortar refers to a granular or powdery material that is physically mixed in a certain proportion with aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) that have been dried and screened. It is transported to the construction site in bags or bulk, mixed with water, and can be directly used. Also known as mortar dry powder, dry mix, dry mix powder, some building adhesives also belong to this category. Dry powder mortar plays a bonding, cushioning, protective, and decorative role in the construction industry as a thin layer, and is widely used in construction and decoration engineering.
Sand is the main raw material for producing dry powder mortar, and the production of dry powder mortar requires a large amount of raw sand. China's annual demand for construction sand is over one billion tons. With a large amount of mining, natural sand and stone resources in China have become quite scarce, and the price of sand is getting higher and higher, leading to a prominent supply-demand contradiction.
The use of dry powder mortar stabilizer can improve the mortar's own anti sagging ability, enhance bonding strength and anti sliding ability, and prolong the mortar's opening time. Substances used to improve the performance of cement mortar belong to the category of concrete admixtures. The main function is to improve the workability and water retention of mortar, improve the efficiency of masonry, reduce ground ash, and save cement and lime paste. It mainly plays a role in diffusion of cement, emulsification and foaming in mortar. It can overcome common problems such as shell peeling and cracking. It is best used as a base or surface layer on the ground of inflatable concrete and ordinary concrete. The mortar used in masonry has a high degree of fullness, and after hardening, it has functions such as frost resistance, water reduction, anti-seepage, durability, crack resistance, insulation, and heat insulation.
The above is a summary of knowledge about dry powder mortar for you. We hope it will be helpful to you. If you have any questions, please feel free to contact us and follow us to learn more about coating production.
