MHEC powder for Indonesia
MHEC powder- The Solution to Indonesia's Building Construction Struggles
Indonesia, a country with a growing demographic and developing economy, requires a significant revamp that involves critical infrastructure development. To achieve this goal, developers are continuously challenging themselves to build durable buildings, bridges, and other assets to cater to the needs and protect the country's growing population. In recent years there has been a shift in the construction market as experts are now opting to use MHEC powder to improve their building construction.
MHEC powder is a new addition to the building material market that enhances the properties of cement and improves the workability of construction solutions. It is a type of cellulose-based ether powder that is free-flowing, white, and odourless. MHEC powder has a significant influence on hydraulic cement, as it functions as a water retention agent and thickener. Due to its exceptional properties, it is now becoming a popular solution for Indonesia's construction industry.
One of the main reasons why MHEC powder is the perfect solution for Indonesia is its compatibility with different cement types. MHEC powder works with Portland cement, Slag cement, and pozzolanic cement. This property is advantageous for the Indonesian construction industry because the country uses different types of cement for different types of constructions.
MHEC powder has a high demand worldwide, and the product is popular in countries such as Malta, United States, Palestine, Morocco, and Singapore. It is an indicator that MHEC powder is an excellent solution for different climate zones, humidity levels, and environmental conditions.
In conclusion, it is essential for construction experts in Indonesia to recognize the benefits of MHEC powder and incorporate it into their building structures. The demand for unique and more complex infrastructures is increasing, and MHEC powder presents an opportunity to enhance building functionalities. By using MHEC powder, the construction industry in Indonesia can build better, stronger, and more long-lasting structures, while meeting the growing demand for sustainable development in the country.

What is the relationship between the gelation temperature of hydroxypropyl methylcellulose (HPMC) and something else?
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.
HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
1. Hot water dissolution method: HPMC does not dissolve in hot water, but it can disperse evenly in hot water initially and then rapidly dissolve upon cooling. There are two typical methods described as follows:
(1) Place the required amount of hot water in a container and heat it to approximately 70°C. Gradually add HPMC while stirring slowly. Initially, HPMC will float on the water's surface and gradually form a slurry, which cools down under stirring.
(2) Add 1/3 or 2/3 of the required amount of water to a container and heat it to 70°C. Disperse HPMC according to method (1) to prepare a hot water slurry. Then, add the remaining cold water to the hot water slurry and cool the mixture after stirring.
2. Powder mixing method: Mix HPMC powder with a large amount of other powdered substances using a blender. Afterward, add water for dissolution. In this case, HPMC can dissolve without clumping because each tiny corner of the powder contains only a small amount of HPMC, which dissolves immediately upon contact with water. This method is commonly used in putty powder and mortar production.
What is the main function of HPMC in putty powder and does it undergo a chemical reaction?
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.
Several dissolution methods of Hydroxypropyl methyl cellulose (HPMC)
In simple terms, "non-ionic" refers to a substance that does not ionize in water. Ionization refers to the process in which electrolytes dissolve in specific solvents (such as water or alcohol) and dissociate into freely moving charged ions. For example, table salt we consume daily—sodium chloride (NaCl)—when dissolved in water, ionizes and produces freely moving sodium ions with a positive charge and chloride ions with a negative charge. In other words, when HPMC is placed in water, it does not dissociate into charged ions but exists in molecular form.
