Hydroxypropyl methylcellulose is a non-ionic cellulose ether obtained from refined cotton, a natural polymer material, through a series of chemical processes. Mainly used in the construction industry: water-resistant putty powder, putty paste, tempered putty, paint glue, masonry plastering mortar, dry powder insulation mortar and other dry powder building materials.
Hydroxypropyl methylcellulose has a good water retention effect, is easy to apply, and has a variety of viscosities to choose from, which can meet various needs.
Hydroxypropyl methylcellulose ether with good performance can significantly improve the construction performance, pumping and spraying performance of mortar, and is an important additive in mortar.
1. Hydroxypropyl methyl cellulose ether has excellent water retention performance and is widely used in various mortars, including masonry mortars, plastering mortars and ground leveling mortars, to improve the bleeding of mortars.
2. Hydroxypropyl methyl cellulose ether has a significant thickening effect, improves the construction performance and workability of the mortar, changes the fluidity of the product, achieves the desired appearance effect, and increases the fullness and use volume of the mortar.
3. Because hydroxypropyl methyl cellulose ether can improve the cohesion and operability of mortar, it overcomes common problems such as shelling and hollowing of ordinary mortar, reduces blanking, saves materials, and reduces costs.
4. Hydroxypropyl methyl cellulose ether has a certain retarding effect, which can ensure the operable time of the mortar and improve the plasticity and construction effect of the mortar.
5. Hydroxypropyl methyl cellulose ether can introduce a proper amount of air bubbles, which can greatly improve the antifreeze performance of the mortar and improve the durability of the mortar.
6. Cellulose ether plays the role of water retention and thickening by combining physical and chemical effects. During the hydration process, it can produce substances that cause micro-expansion properties, so that the mortar has a certain micro-expansion property and prevents the mortar from hydration in the later stage. The cracking caused by shrinkage in the middle increases the service life of the building.
