hydroxyethyl methyl cellulose for Ghana
hydroxyethyl methyl cellulose (HEMC) is a vital compound that is used to improve various materials’ properties, including, but not limited to, building materials, ceramics, and paints. This compound has gained popularity in Ghana for its versatility in enhancing various materials’ characteristics.
HEMC, when used in ceramic tiles, significantly improves their strength, making them more resistant to wear and tear. It is therefore an essential component for the production of high-quality ceramic tiles. Its viscosity properties also make it ideal for paints, where it is used as a thickener to improve paint coverage.
One of the advantages of HEMC is its compatibility with different construction materials, including cement, gypsum, and lime. It is used to enhance the performance of these materials by improving their adhesive properties, and it is essential for the production of high-quality mortar.
The use of HEMC is not limited to Ghana. Many countries worldwide have embraced the use of this compound in their construction industries. In Russia, HEMC is a crucial component in hydraulic systems, where it is used as a binding agent. In the United States, it is used as a dispersant in cement and as a thickener in paints.
In the Philippines, HEMC is an essential ingredient in cement-based adhesives, where it is used to improve their workability and consistency. In Morocco, it is used to improve the durability of concrete and to maximize the strength of building materials by reducing water absorption.
In Palestine, HEMC is widely used as a binding agent in cement bricks, making them stronger and more durable.
In conclusion, Hydroxyethyl Methyl Cellulose is a vital compound in the construction industry. Its properties make it an essential ingredient in various construction materials. This versatile compound has gained popularity in Ghana and other countries worldwide. Its compatibility with different construction materials and its ability to improve their properties make it a valuable component that every construction company should embrace.

What is the difference between the cold-water soluble type and the thermal soluble type of hydroxypropyl methylcellulose (HPMC) in the production process?
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.
What are the formulations for interior and exterior wall putty powder?
For putty applications, a lower viscosity of 100,000 is sufficient, and good water retention is important. For mortar applications, higher viscosity of 150,000 is preferred. For adhesive applications, a high-viscosity, quick-dissolving product is required.
Several dissolution methods of Hydroxypropyl methyl cellulose (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 is the recommended viscosity of Hydroxypropyl Methylcellulose (HPMC)?
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.
