HPMC (Hydroxypropyl Methyl Cellulose Ether) is a synthetic non-toxic, odorless, colorless water-soluble polymer. It is a cellulose ether compound obtained by chemically modifying cellulose and is commonly used in various industrial and commercial applications.
Key features of HPMC include:
1. Water Solubility:
HPMC has good solubility in water and forms a viscous solution.
2. Water retention:
HPMC can absorb and retain water, improving the moisture retention performance of the material.
3. Good adhesion:
HPMC can form a uniform film on various surfaces, increasing the adhesion of the material.
4. Adjust viscosity:
The viscosity of HPMC can be controlled by adjusting its molecular weight and concentration, so as to adapt to different application requirements.
In the construction industry.HPMC is often used in cement mortar, tile adhesive, wall coating and other products to improve fluidity, improve adhesion and crack resistance.
The price of HPMC cellulose is determined by many factors, including but not limited to the following aspects:
l Market supply and demand: supply and demand is one of the main factors that determine prices. If market demand is higher than supply, prices may rise; conversely, if there is excess supply, prices may fall.
l Raw material cost: The production of HPMC requires the use of cellulose as a raw material, and the price of cellulose is affected by many factors, such as the cost of raw materials such as wood and pulp, as well as procurement and processing costs.
l Production cost: The production of HPMC requires chemical synthesis and processing technology, including reactor equipment, energy consumption, labor costs, process improvement, etc. These factors will have an impact on the cost of production, thereby affecting the pricing of the product.
l Brand and market position: Different brands of HPMC cellulose have different popularity and reputation in the market. Established brands may set higher prices, while emerging brands may enter the market at competitive prices.
l Supply chain and transportation costs: HPMC is usually a product of global trade, and supply chain and transportation costs will also have an impact on the price. This includes procurement of raw materials, location of production facilities, transportation distances, packaging and storage costs, etc.
l Technology and R&D investment: The quality and performance of HPMC cellulose are also related to R&D investment and technological innovation. Advanced production technology and improved product quality may affect the price of the product.
To dissolve HPMC (Hydroxypropyl Methylcellulose) cellulose, you can follow these steps:
Choose a suitable solvent: HPMC is typically soluble in cold water, so water is commonly used as the primary solvent. However, the solubility of HPMC may vary depending on the grade and viscosity of the specific HPMC product. It's recommended to check the product specifications or consult the manufacturer for guidance on the appropriate solvent.
Prepare the solvent: Measure the desired amount of solvent (water) based on the required concentration of the HPMC solution. It's generally recommended to add the HPMC to the solvent rather than the other way around to ensure proper dissolution.
Gradually add HPMC to the solvent: Sprinkle the HPMC powder into the solvent while continuously stirring. It's important to add the HPMC gradually to prevent clumping and ensure proper dispersion in the solvent.
Continue stirring: Keep stirring the mixture until the HPMC powder is fully dispersed in the solvent. It may take some time and gentle agitation to achieve complete dissolution. A mechanical mixer or a high-shear mixer can be used to accelerate the dissolution process.
Optional: If necessary, you can adjust the pH or temperature of the solution as specified by the application requirements or manufacturer's instructions. However, it's important to note that extreme pH levels or temperatures may affect the solubility or stability of the HPMC solution.
Viscosity refers to the resistance of a fluid to flow. In the case of Cellulose HPMC CPS, viscosity is an important characteristic that determines its performance in different applications. The viscosity of Cellulose HPMC CPS can vary depending on various factors such as the grade or type of HPMC, the concentration of the polymer in a solution, temperature, and shear rate.
The viscosity of Cellulose HPMC CPS is typically measured using a viscometer or rheometer. It is commonly reported in units such as centipoise (cP) or millipascal seconds (mPa·s).
Specific viscosity values for Cellulose HPMC CPS can vary widely depending on the grade and manufacturer. Generally, the viscosity of Cellulose HPMC CPS ranges from a few hundred to several hundred thousand centipoise (cP) or millipascal seconds (mPa·s) in a 2% to 5% concentration solution at 20°C. However, it's important to note that these values are approximate and should be obtained from the specific manufacturer or supplier, as they can provide more accurate information for their specific products and grades.
