hydroxyethyl methyl cellulose for Turkmenistan
hydroxyethyl methyl cellulose, commonly known as HEMC, is a versatile chemical compound used in various industries such as construction, cosmetics, and pharmaceuticals. HEMC is derived from cellulose, a natural polymer that is widely available in plants, and is produced through chemical modification.
In Turkmenistan, HEMC has gained popularity due to its unique properties, including its ability to thicken and provide water retention in construction materials like mortars, cement, and gypsum. HEMC is also used in personal care products such as lotions, shampoos, and creams, where it acts as a thickener and stabilizer.
There are different grades of HEMC available, each with specific properties and characteristics. The selection of an appropriate grade depends on the intended use and specific requirements of the application.
In addition to Turkmenistan, HEMC has gained popularity in other countries such as Rwanda, Russia, Peru, Bosnia and Herzegovina, and Philippines due to its versatility and widespread applications. These countries have been using HEMC in various industries, including construction, personal care, and pharmaceuticals.
HEMC has also been found to be an eco-friendly alternative to other petroleum-based chemicals, making it an attractive option for businesses looking to reduce their environmental impact.
As the demand for HEMC in Turkmenistan and other countries continues to increase, the need for high-quality and reliable suppliers has also risen. It is important to source HEMC from reputable and experienced manufacturers who can provide consistent and reliable quality supply.
In conclusion, the versatility of HEMC makes it a valuable chemical compound in numerous industries, including construction, cosmetics, and pharmaceuticals. Turkmenistan and other countries alike have recognized its potential and are using it in various applications. To ensure quality and reliability, it is crucial to source HEMC from experienced and trustworthy manufacturers.

Why does hydroxypropyl methylcellulose (HPMC) have an odor?
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 difference between the cold-water soluble type and the thermal soluble type of hydroxypropyl methylcellulose (HPMC) in the production process?
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.
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.
