In the production of building materials, hydroxypropyl methyl cellulose ether is an indispensable additive. After adding HPMC, the following performance can be improved:
1. Water retention - - -Enhance water retention, improve cement mortar, dry powder putty too fast drying and insufficient hydration cause poor hardening, cracking and other phenomena.
2. Workability - - - Increase the plasticity of mortar, improve the industriality of construction steamed coating, and improve work efficiency;
3. Adhesion - due to the improved plasticity of the mortar, it can better bond the substrate and the adherend;
4. Anti-sag - due to its thickening effect, it can prevent the occurrence of slippage of mortar and adherends during construction
