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.

What are the formulations for interior and exterior wall putty powder?
1. Whiteness: Although whiteness alone does not determine the usefulness of HPMC, higher-quality products usually have better whiteness.
2. Fineness: HPMC is typically available in 80 and 100 mesh sizes, with fewer options in 120 mesh. Finer particles generally indicate better quality.
3. Transmittance: When HPMC is dissolved in water and forms a transparent colloidal solution, higher transmittance indicates fewer insoluble impurities.
4. Specific gravity: Higher specific gravity is generally better. A higher specific gravity is often due to a higher content of hydroxypropyl, which results in better water retention.
What are the other names for 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.
Several dissolution methods of 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.
What are the differences between HPMC and MC?
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.
