What is the role of hydroxypropyl methyl cellulose in use
July 9, 2020
Hydroxypropyl methylcellulose should be very extensive, basically in construction sites, industry, chemical medicine, etc. will be applied to hydroxypropylmethyl cellulose, then hydroxypropyl methyl cellulose should be used when using What, what use knowledge do you have? Briefly introduce to you.
1. The high water retention of construction mortar plastering mortar can fully hydrate the cement and significantly increase the bonding strength. At the same time, it can appropriately increase the tensile strength and shear strength, greatly improve the construction effect and improve the work efficiency.
2. Water-resistant putty hydroxypropyl methylcellulose in putty mainly serves to retain water, bond and lubricate, avoid cracks and dehydration caused by excessive water loss, and at the same time enhance the adhesion of putty and reduce sagging during construction It is a smooth and successful construction.
3. The whitewashed gypsum series of hydroxypropyl methylcellulose in gypsum series products mainly play a role in water retention, thickening, lubrication, etc. At the same time, it has a certain retarding effect, which solves the problem that the initial strength cannot be reached during the construction process. Problems can extend working hours.
4.The higher water retention of the tile adhesive eliminates the need to pre-soak or wet the tiles and bases, which significantly improves their bonding strength.The slurry can be constructed for a long period, delicate, uniform, and easy to construct, while having good resistance to migration Sex.
5. Latex paint in the coating industry can be used as a film-forming agent, thickener, emulsifier and stabilizer, so that the film has good wear resistance, uniformity and adhesion The PH of improving the surface tension and improving the surface tension is qualitative, and the miscibility with organic solvents is also good. The high water retention performance makes it have good brushability and river flatness.
