Introduction of Landcel HPMC
The alias of Hydroxypropyl methyl cellulose is hypromellose; cellulose hydroxypropyl methyl ether, English abbreviation: HPMC, It uses cotton cellulose as raw material, and is produced by special etherification under alkaline conditions , the whole process is completed under automated monitoring and does not contain any organs, oils and other active ingredients. This product is a non-ionic cellulose ether with a white powder appearance, odorless and tasteless.
HPMC is widely used in construction materials, coatings, resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. At present, most HPMC produced in China is of construction grade. In construction grade, putty powder (dry mix)is used in a large amount, actually about 90% is used for putty powder, and the rest is used for cement mortar and glue. As a water-retaining agent and retarder of cement mortar, it makes the mortar more workable. Used as a binder in plaster, plaster, putty powder or other building materials to improve work-ability and prolong operation time. It can be used as tile adhesive, marble, decoration, rising the adhesive strength, and can reduce the usage amount of cement. The water retention properties of HPMC prevent the final products from cracking due to drying too fast after application, and enhance the strength after hardening.
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the types used in Putty powder is with the Vis of 100,000(NDJ), but in mortar, 150,000-200,000(NDJ) is better. Moreover, the most important role of HPMC is water retention, followed by thickening. In putty powder, as long as the water retention is good, the viscosity is low (70,000-80,000), it is also possible, of course, the viscosity is higher, and the relative water retention is better. The HPMC produced by Landcel can meet the needs of different customers. Whether it is a self-leveling mortar with a viscosity of 300 or a high-viscosity tile adhesive
