HEMC powder for Indonesia
HEMC powder for Indonesia: A Solution for Improved Construction
As Indonesia's infrastructure development continues to grow at a rapid pace, so does the demand for high-quality construction materials. Among these materials is the Hydroxyethyl Methylcellulose (HEMC) powder, a water-soluble polymer designed to improve the performance of building materials such as mortar, cement, and plaster.
HEMC powder plays a significant role in the construction industry, improving the workability, consistency, and adhesion of building materials. It enhances the strength of mortar and reduces shrinkage, making it more durable and long-lasting. HEMC powder is known for its exceptional properties such as viscosity control, water retention, and thickening, making it ideal for high-performance construction.
However, it is worth noting that not all HEMC powders in the market are created equal. Therefore, consumers need to be cautious in selecting the right product that meets their intended application. In this regard, HEMC powders from trusted manufacturers such as those with global presence and a track record in the industry like the ones from India, Philippines, Pakistan, Palestine and Peru should be given priority.

What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?
HPMC has three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any reaction. The formation of bubbles in putty powder can be caused by two reasons: (1) Excessive water content. (2) Applying another layer on top before the bottom layer has dried, which can also lead to the formation of bubbles.
Several dissolution methods of Hydroxypropyl methyl cellulose (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?
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.
What is the difference between the cold-water soluble type and the thermal soluble type of hydroxypropyl methylcellulose (HPMC) in the production process?
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.
