hydroxyethyl methyl cellulose for Brazil

hydroxyethyl methyl cellulose for Brazil: Benefits and Applications Hydroxyethyl methyl cellulose, also known as HEMC, is a cellulose ether widely used in construction and building materials due to its exceptional properties. From cement-based mortars to wallpaper adhesives, HEMC provides better workability, uniformity, and stability to various applications. HEMC is a water-soluble polymer derived from natural cellulose through chemical modification. Its unique hydrophilic and hydrophobic groups make it an excellent thickener, binder, and lubricant for a variety of materials. Brazil may be one of the largest cement producers in the world, but it still faces challenges in terms of construction quality, durability, and sustainability. HEMC can help address these challenges by providing enhanced rheological performance, water retention, and adhesive strength to cement-based products. HEMC is compatible with various types of cement, including Ordinary Portland Cement (OPC), Pozzolanic Portland Cement (PPC), and Slag Cement (SC). It can improve the workability of dry mixtures and prevent sagging, bleeding, and cracking during application and curing. In addition to cement-based products, HEMC can also be used in other construction materials such as plaster, render, mortar, and grout. It improves the homogeneity and cohesiveness of wet mixtures and reduces the risk of segregation and shrinkage. HEMC is also suitable for non-construction applications such as personal care, pharmaceuticals, and food. It can act as a stabilizer, emulsifier, and thickener for various products, including lotions, gels, ointments, pills, and sauces. The quality and performance of HEMC depend on various factors such as the degree of substitution, viscosity, and purity. Therefore, it is essential to choose a reliable supplier that can provide consistent and high-quality HEMC. As a leading HEMC supplier in the United States, Pakistan, Singapore, Rwanda, and the Philippines, we offer a range of grades and specifications to meet different needs and requirements.

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.

Technical Guidelines for Hydroxypropyl Methylcellulose (HPMC)

As a professional manufacturer of architectural-grade HPMC, we provide you with comprehensive technical guidance and problem-solving support throughout the production and application processes.

How much do you know about Hydroxypropyl methyl cellulose(HPMC)?

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.

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

Faq

What is the main use of 1-Hydroxypropyl methylcellulose (HPMC)?

HPMC can be divided into two types: instant soluble and heat soluble. Instant soluble HPMC quickly disperses in cold water, disappearing in the water. At this stage, the liquid does not have viscosity because HPMC is only dispersed in the water and not completely dissolved. After about 2 minutes, the viscosity of the liquid gradually increases, forming a transparent and viscous colloidal solution. Heat soluble HPMC tends to agglomerate in cold water but can rapidly disperse in hot water, disappearing in it. As the temperature decreases to a certain point, viscosity slowly appears until a transparent and viscous colloidal solution is formed. Heat soluble HPMC can only be used in putty powder and mortar, as it tends to agglomerate in liquid adhesives and coatings and cannot be used effectively. Instant soluble HPMC has a wider range of applications and can be used in putty powder, mortar, liquid adhesives, and coatings without any restrictions.

Is there any relationship between powder loss in putty and HPMC?

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 other names for Hydroxypropyl Methyl Cellulose (HPMC)?

For putty powder, a viscosity of around 100,000 is generally sufficient, while mortar requires a higher viscosity, around 150,000, to be effective. Moreover, the most important function of HPMC is water retention, followed by thickening. In putty powder, as long as it has good water retention and a lower viscosity (70,000-80,000), it can still be used. Of course, a higher viscosity provides relatively better water retention. However, when the viscosity exceeds 100,000, the impact of viscosity on water retention becomes less significant.

Several dissolution methods of Hydroxypropyl methyl cellulose (HPMC)

The dosage of HPMC in actual application varies depending on factors such as climate, temperature, local lime and calcium quality, putty powder formulation, and the desired quality specified by the customer. Generally, it ranges between 4 kg to 5 kg. For example, in Beijing, most putty powders use around 5 kg; in Guizhou, it is mostly 5 kg in summer and 4.5 kg in winter; in Yunnan, the dosage is smaller, usually around 3 kg to 4 kg, and so on.
