Hydroxypropyl Methyl Cellulose Chemical Additives in dry powder mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, and it is a main additive that affects the construction performance of mortar. HPMC in dry powder mortar mainly plays the role of water retention, thickening and improving construction performance.
1. HPMC Hydroxypropyl Methylcellulose Chemical Cellulose is used in construction mortar plastering mortar. High water retention can make the cement fully hydrated, significantly increase the bond strength, and at the same time, it can appropriately increase the tensile strength and shear strength, greatly improve the construction effect and improve work efficiency.
2. Hydroxypropyl methylcellulose water-resistant putty In the putty, hydroxypropyl methylcellulose cellulose ether mainly plays the role of water retention, bonding and lubrication, avoiding cracks and dehydration caused by excessive water loss, and at the same time strengthening Improve the adhesion of putty, reduce the sagging phenomenon during construction, and make the construction smoother.
3. Hydroxypropyl methylcellulose plastering plaster series Among the gypsum series products, hydroxypropyl methylcellulose cellulose ether mainly plays the role of water retention and lubrication, and has a certain retarding effect, which solves the problem of bulging in the construction process. The problem of cracking and failure to reach the initial strength can prolong the working time.

Hydroxypropyl Methyl Cellulose Thickening Agent is a propylene glycol ether of methylcellulose, in which both hydroxypropyl and methyl groups are combined with the anhydrous glucose ring of cellulose by ether linkages.
Hydroxypropyl Methyl Cellulose(HPMC) is white to off-white fibrous powder or granules. Soluble in water and some organic solvents.
Application
1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. In plaster, gypsum, putty powder or other building materials as a binder to improve spreadability and prolong work time. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water-retaining performance of HPMC prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening.
2. Ceramic manufacturing industry: It is widely used as a binder in the manufacture of ceramic products.
3. Coating industry: It is used as a thickener, dispersant and stabilizer in the coating industry, and has good compatibility in water or organic solvents. As a paint remover.
4. Ink printing: It is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents.
5. Plastic: used as forming release agent, softener, lubricant, etc.
6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride, and it is the main auxiliary agent for preparing PVC by suspension polymerization.
7. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; viscosity-increasing agents
8. Others: It is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.
