Cellulose Ether Factory

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained by cellulose alkalization, etherification, neutralization and washing. HPMC has good thickening, dispersing, emulsifying, film-forming properties, etc. It is the first choice for production of high quality building materials additives.

 

In daily chemical or detergent applications, the HPMC powder is mainly used for thickening, foaming, stable emulsification, dispersion, adhesion, film formation and water retention of cosmetics. High viscosity products are used for thickening, and low viscosity products are mainly used for suspension dispersion and film formation.

 

The addition of redispersible emulsion powder (VAE/RDP)to the mortar can increase the cohesion, cohesion and flexibility of the mortar. First, it can improve the water retention of the mortar, form a film, and reduce the evaporation of water. Second, it can improve the bond strength of mortar.

 

Construction grade HPMC properties:
1. Thickening: Cellulose can thicken to suspend, keep the solution uniform and consistent, and resist sagging.

2. Water retention: Make the putty powder dry slowly, and assist the reaction of lime calcium under the action of water.

3. Easy Construction: Cellulose has a lubricating effect, which can make the putty powder have good workability.

Application

Hydroxyethyl cellulose(HEC)

The most important property of hydroxyethyl cellulose powder is that it acts as a thickener, in creasing the viscosity of the liquid,and its thickening depends on its concentration. If you're searching for a versatile solution that enhances the performance of your products, look no further than Hydroxyethyl Cellulose (HEC) powder.

Gypsum Special Grade HPMC

The gypsum special grade hydroxypropyl methyl cellulose HPMC has the characteristics of high water retention, dispersibility, good fineness, good workability and easy dissolution. widely used in gypsum products like gypsum plaster, adhesive plaster, embedded gypsum, tile adhesives etc.

Daily Chemical Products Additive

Daily Chemical HPMC has a variety of properties such as thickening, foam stabllization,emulifiation, and easy dispersion. Shampoo Additive HPMC has good compatibility with various additives of other daily chemical products. It is widely used in detergents, shower gels, shampoos, hand sanitizers, and laundry liquid and other products.

Tile Adhesive Additive

Tile Adhesive Additive HPMC can ensure the smooth construction on difterent base surtaces, even when the ambient temperalure is relalively harsh, the tile adhesive can be given a long enough open time and adjustable time.

Gypsum Additive

In gypsum products, the focus is on water retention, retardation and lubrication. Different gypsum has different effects on product performance, so thickening, water retention, and retardation determine the quality of gypsum building materials.

Mortar Additive

Adding hydroxypropyl metylellulose can improve anti-sip performance, improve wetting performance, thicken, improve batch scraping and slipping, easy to level, improve surface performance and strength, and have very good compatibility with other additives.

Putty Powder Additive

Hydroxypropyl metylcellulose is a commonly used raw material in powdered building materials, which greatly improves the slip performance and anti-sag performance of the construction, improves the wettability, improves the anti-slip performance of the putty, improves the leveling effect of the putty, and improves the construction eficlency.

How to improve the adhesion of putty

When encountering the projects that have been constructed, it is found that the adhesion of putty on the exterior wall is poor, the following methods can be adopted to improve the adhesion of putty:

Dissolution Method

Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Goon stirring until it cools down and becomes clear

Quick Find

Faq

  • What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?

    The viscosity of HPMC is inversely proportional to temperature, meaning that viscosity increases as temperature decreases. When we refer to the viscosity of a certain product, it generally refers to the measurement result of its 2% water solution at 20 degrees Celsius. In practical applications, in regions with large temperature differences between summer and winter, it is advisable to use relatively lower viscosity during winter for better construction. Otherwise, at low temperatures, the viscosity of the cellulose increases, resulting in a heavier feel during application. Medium viscosity: 75,000-100,000 (mainly used for putty) Reason: Good water retention. High viscosity: 150,000-200,000 (mainly used for polystyrene particle insulation mortar powder and foamed glass bead insulation mortar) Reason: High viscosity, reduces mortar dusting and sagging, improves construction. However, in general, higher viscosity provides better water retention. Therefore, many dry mortar manufacturers consider using medium-viscosity cellulose (75,000-100,000) instead of low-viscosity cellulose (20,000-40,000) to reduce the dosage and costs.
  • What are the formulations for interior and exterior wall putty powder?

    The main raw materials for Hydroxypropyl Methylcellulose (HPMC) include refined cotton, chloromethane, epichlorohydrin, and other materials such as soda ash, acid, toluene, isopropanol, etc.
  • What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?

    HPMC is widely used in industries such as construction materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, agriculture, cosmetics, and tobacco. HPMC can be classified into architectural grade, food grade, and pharmaceutical grade based on its application. Currently, most domestically produced HPMC falls under the architectural grade category. In the architectural grade, a large amount of HPMC is used in putty powder, accounting for approximately 90% of its usage, while the rest is used in cement mortar and adhesives.
  • How many types does 2-Hydroxypropyl methylcellulose (HPMC) have, and what are the differences in their applications?

    The two main indicators most users are concerned about are the content of hydroxypropyl and viscosity. Higher hydroxypropyl content generally indicates better water retention. A higher viscosity also provides relatively better water retention (not absolute), and HPMC with higher viscosity is more suitable for cement mortar.
