HPMC in dry powder mortar

Hydroxypropyl methylcellulose 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.

Hydroxypropyl methylcellulose The cellulose ether used in dry powder mortar is mainly hydroxypropyl methylcellulose ether (HPMC). In the new honeycomb ceramics, it can give lubricity to the blank. In the coating industry, it can be used as a thickener, dispersant and stabilizer in the coating industry, and has good compatibility in water or organic solvents. As a paint remover. Ink printing: It is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents. .Plastic: used as forming release agent, softener, lubricant, etc. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride, and is the main auxiliary agent for preparing PVC by suspension polymerization. Hydroxypropyl methylcellulose Others: This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.

HPMC in dry powder mortar mainly plays the role of water retention, thickening and improving construction performance. The high water retention of construction mortar and plastering sand 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 improving work efficiency. Water-resistant and greasy 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 enhancing the adhesion of the putty and reducing the construction time. The middle sag phenomenon makes the construction smoother. Among the gypsum series products, hydroxypropyl methylcellulose cellulose ether mainly plays the role of water retention and lubrication, and at the same time has a certain retarding effect, which solves the problems of drum cracking and initial strength failure during construction. , can extend working hours. Hydroxypropyl methylcellulose interface agent is mainly used as a thickener, which can improve tensile strength and shear strength, improve surface coating, enhance adhesion and bonding strength. Properties: This product is a white or slightly yellowish powder, odorless, tasteless and non-toxic. Water retention and increased strength. , putty powder or other building materials as a binder to improve spreadability and prolong operable 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. Ceramic manufacturing: It is widely used as a binder in the manufacture of ceramic products. PH stability: The viscosity of the aqueous solution of this product is relatively stable in the range of PH3.0-11.0. Water retention effect: Hydroxypropyl methylcellulose is hydrophilic and its aqueous solution is highly viscous. Hydroxypropyl methylcellulose (HPMC) is added to mortar, gypsum, paint, etc. to maintain high water retention in the product. Shape retention: Compared with other water-soluble polymers, the aqueous solution of this product has special viscoelastic properties. Its addition can improve the shape-invariant ability of extruded ceramic products, etc.

Lubricity of hydroxypropyl methylcellulose (HPMC): Adding this product can reduce the friction coefficient and improve the lubricity of extruded ceramic products and cement products. Film-forming properties: This product can produce strong, flexible, and transparent sheets with good oil and ester resistance, especially the water retention and unique construction of hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose The film-forming property of cellulose has been at the forefront in China.
