Knowledge of the use of hydroxypropyl methylcellulose


1. Construction mortar and plastering mortar: High water retention can fully hydrate the cement and significantly increase the bond strength. At the same time, it can appropriately increase the tensile strength and shear strength, greatly improving the construction effect and increasing work efficiency.

2. Water-resistant putty: In the putty, hydroxypropyl methylcellulose mainly plays the role of water retention, bonding and lubrication, avoiding cracks and dehydration caused by excessive water loss, and at the same time enhancing the adhesion of the putty and reducing the flow during construction. Hanging phenomenon, so that the construction is relatively smooth.

3. Plaster plaster series: in gypsum series products, hydroxypropyl methylcellulose mainly plays the role of water retention, thickening and lubrication. At the same time, it has a certain retarding effect, which solves the problems of drum cracking and initial strength not reaching during the construction process, and can prolong the working time.

4. Exterior thermal insulation mortar for exterior walls: Hydroxypropyl methylcellulose plays a key role in bonding and increasing strength in this material, making the mortar easier to apply and improving work efficiency. At the same time, it has anti-sag effect and high water retention The performance can prolong the working time of the mortar, improve the resistance to shrinkage and cracking, improve the surface quality and improve the bonding strength.

5. Tile Adhesive: High water retention does not need to pre-soak or wet the tile and the base, significantly improving its bonding strength. The slurry can be used for a long construction period, fine and uniform, convenient construction, and has good anti-moisture migration sex.

6. Latex paint coating: In the coating industry, hydroxypropyl methylcellulose can be used as a film-forming agent, thickener, emulsifier and stabilizer, so that the film has good wear resistance, leveling property, adhesion The PH of adhesion and surface tension improvement is qualitative, and the miscibility effect with organic solvents is also good. The high water retention performance makes it have good brushing and leveling properties.
