Hydroxypropyl methyl cellulose (HPMC) Applications

Hydroxypropyl methyl cellulose in dry mortar, the amount of cellulose ether is very low, but it can significantly improve the performance of the wet mortar, is a major influence performance additive mortar construction. Now, hydroxypropyl methyl cellulose, cellulose ethers are used in dry mortar mainly hydroxypropyl methyl cellulose ether (HPMC). Hydroxypropyl methyl cellulose HPMC in dry mortar plays a major water retention, thickening, improve the workability and so on.

1, building mortar plastering mortar

     High water retention can fully hydrated cement, significantly increase the bond strength, while appropriate to improve the degree of tensile and shear strength, greatly improve the construction effects, improve work efficiency.

2, water putty

     Hydroxypropyl methyl cellulose in putty cellulose ether mainly from water retention, adhesion and lubrication effect, to avoid cracks and lead to dehydration due to excessive water loss, while enhancing the putty adhesion, reduced flows linked to construction phenomenon, so that the construction is relatively smooth.

3, wall plaster series

     Gypsum products among hydroxypropyl methyl cellulose, cellulose ether mainly from water retention, increased lubrication and so on, but also has some retarding effect, solves the construction process drum cracking reach the initial intensity of the problem, may be extended operating hours.

4, interface agent

     The main use as a thickener, can improve the tensile strength and shear strength, improve surface coating to enhance adhesion and bonding strength.

5, exterior insulation mortar

Hydroxypropyl methyl cellulose, cellulose ether in the focus of this material from the bonding, increase the role of intensity, so that the mortar is more easily applied, improve work efficiency, but also has anti-sagging effect, higher water retention may be extended mortar work time and increase anti-shrinkage and crack resistance, improved surface quality, improve bond strength.

6, tile adhesives

Higher water retention may not have pre-soak or wet tile and base, significantly improve their bond strength, the slurry can be long construction period, fine, uniform, convenient construction, but also has good resistance to embellish metastatic.

7, caulks, grouts

Add hydroxypropyl methyl cellulose cellulose ethers it has a good edge adhesion, low shrinkage and high abrasion resistance, protecting the base material against mechanical damage, avoiding the penetration to bring the building influences.

8, self-leveling material

Hydroxypropyl methyl cellulose, cellulose ethers and stable adhesion to ensure a good flow and self-leveling capability, making it possible to control the rate of water retention rapid solidification, reduce cracking and shrinkage.

  Hydroxypropyl methylcellulose (HPMC) Product Properties

Properties: This product is a white or slightly yellow powder, and odorless, tasteless, non-toxic.

Water solubility and thickening ability: This product can dissolve in water, forming a transparent viscous solution.

Dissolved in an organic solvent: Because a certain amount of hydrophobic methoxy group, so this product can be dissolved in some organic solvents, can be dissolved in water and organic solvents mixed.

Hydroxypropyl methyl cellulose (HPMC) Salt Resistance: Since the product is non-ionic and non-polymeric electrolyte, therefore, it is relatively stable in aqueous solution of metal salts or organic electrolytes.

Surfactant: aqueous solution of this product has a surface activity, it has emulsification, protective colloids and relative stability.

Thermal gelation: When heated above a certain temperature, the product can become opaque solution, a precipitate, the solution loses viscosity. But it was transformed into the original state and then gradually cooled. Temperature condensation and precipitation occurs depends on the type, concentration and heating rate product solution.

Low ash content: Because this product is non-ionic, can be washed with hot water during the manufacturing process effectively refined, so its very low ash content.

PH stability: The viscosity of the aqueous solution within PH3.0-11.0 product range are relatively stable.

Retention effect: Because this product is an aqueous solution of hydrophilic and it is a high viscosity. Hydroxypropyl methyl cellulose (HPMC) added to the mortar, plaster, paint, etc., in the products maintain high water retention effect.

Shape retention: Compared with other water-soluble polymer, an aqueous solution of this product has special viscoelastic properties. It added the ability to improve the shape of the ceramic article unchanged extrusion.

Hydroxypropyl methyl cellulose (HPMC) lubrication: Join this product can reduce the friction coefficient and improve extruded ceramic products, cement products and lubricity.

Film-forming: This product can generate strong flexible, transparent sheet, and a good performance of oil-resistant ester

In particular, hydroxypropyl methyl cellulose (HPMC) water retention and unique construction, film, has been at the forefront of the country.
