The use of key additives can not only significantly improve the basic performance of mortar, but also drive the innovation of construction technology.
1. Redispersible latex powder
Redispersible latex powder can significantly increase the adhesion, flexibility, water resistance, wear resistance, etc. of ready-mixed mortar. In products or systems such as mortar for external wall insulation, tile adhesive, interface treatment agent, self-leveling mortar, etc., redispersible latex powder plays an indispensable role in solving the problems of avoiding cracking, hollowing, peeling, water seepage, and efflorescence. Role.
Redispersible latex powder is the premise and foundation of dry powder, serialization and specialization of mortar, and it is the source of high added value of ready-mixed mortar. Compared with the two-component polymer modified cement mortar system, the cement-based dry-mix mortar that can be redispersed such as latex powder modified has incomparable advantages in quality control, construction operation, storage and transportation, and environmental protection. Some well-known redispersible latex powder manufacturers have a wide range of product lines based on different chemical compositions for customers to choose from, which can meet the individual performance requirements of different varieties of ready-mixed mortar products.
2. Cellulose ether
Cellulose ether can significantly increase the viscosity of water and has a significant thickening effect. It is a water-retaining thickener widely used in mortar and paint.
Traditional mortar requires the base to be watered and wet to reduce the rate of absorption of moisture in the mortar by the base, and to maintain the moisture in the mortar and the strength of the cement by increasing the thickness of the mortar layer. The ready-mixed mortar added with cellulose ether has a strong ability to retain water, which is the fundamental reason why the ready-mixed mortar does not require the base to be wetted with water and realizes thin-layer construction.
3. Wood fiber
Wood fiber can significantly improve the thixotropy and sagging resistance of mortar, and its strong water conductivity can significantly reduce the possibility of early drying and cracking of mortar and increase the wettability of mortar to the substrate. Wood fiber has been widely used in mortar products such as thermal insulation slurry, putty, tile adhesive, caulking plaster, etc.
4. Thixotropic lubricant
Thixotropic lubricants can significantly improve the homogeneity, pumpability, open time, sag resistance, and scraping properties of mortar.
In addition, for different construction applications, expansion agents, superplasticizers, defoamers, air-entraining agents, coagulation accelerators, retarders, waterproofing agents, early strength agents and inorganic pigments and various functional Additives, while improving the basic performance, can also have special functions such as sound absorption and noise reduction, automatic humidity control, deodorization and smoke removal, sterilization and mildew resistance.
