Notably, the manufacturing process of MHEC powder parallels that of HPMC. However, MHEC powder necessitates the utilization of Ethylene oxide instead of Propylene oxide.

Latex powder — it can improve the consistency and smoothness of the system in the wet mixing state. Due to the characteristics of the polymer, the cohesion of the wet mix is greatly improved, making a great contribution to the workability; After drying, it can provide adhesion to the smooth and dense surface layer, improve the interface effect of sand, stone and air holes, and enrich the film at the interface on the premise that the addition amount is guaranteed, so that the ceramic tile adhesive has a certain flexibility, reduces the elastic modulus, and absorbs the thermal deformation stress to a great extent. In case of water immersion in the later stage, it can also have water resistance, buffer temperature and inconsistent material deformation (ceramic tile deformation coefficient 6 × 10-6/ ℃, deformation coefficient of cement concrete 10 × 10-6/ ℃) to improve weather resistance. Youngcel Hydroxypropyl methyl cellulose HP cellulose — provides good water retention and workability for fresh mortar, especially for the wetted area. In order to ensure the smooth progress of hydration reaction, it can prevent excessive water absorption of substrate and evaporation of surface water. Due to its air entraining property (1900g/l—1400g/lpo400 sand 600HP cellulose 2), the unit weight of ceramic tile adhesive is reduced, materials are saved and the elastic modulus of hardened mortar is reduced.
