4. Dry-Mix Mortars The powder is also a crucial component in the manufacture of dry-mix mortars. Its inclusion not only improves the workability of the mixtures but also enhances their mechanical properties once cured.
Following neutralization, the hydroxyethyl cellulose is typically precipitated from the solution. This can be done by adding a non-solvent (often alcohol or other organic solvents), causing the HEC to aggregate and settle out of the solution.
The production of HEC cellulose involves the reaction of cellulose with ethylene oxide under alkaline conditions. The process begins with the preparation of cellulose, which can be derived from various natural sources, such as wood, cotton, or other plant materials. The cellulose is then treated with a chemical catalyst and ethylene oxide, resulting in the formation of hydroxyethyl groups.
5. Environmental Considerations As a product derived from natural cellulose, HPMC is considered environmentally friendly compared to some synthetic polymers. Its use contributes to the development of sustainable construction materials, aligning with the industry's growing focus on eco-friendly practices.
- In recent years, the price of HPMC powder has been relatively stable, with minor fluctuations due to changes in market conditions. However, the COVID-19 pandemic has caused disruptions in the global supply chain, leading to shortages of raw materials and increased production costs
