- The molecular weight of HEC can vary, which significantly influences its properties and uses. Low molecular weight HEC is more soluble, while high molecular weight types provide better thickening effects. The percentage of hydroxyethyl substitution also plays a crucial role, impacting viscosity and other rheological properties.
- In the construction industry, HPMC is used as an additive in cementitious products such as plaster and mortar. It helps to improve the workability of the mixture, reduces cracking, and increases its resistance to water penetration.
- 1. Weigh the required amount of HPMC based on the desired concentration.
- Technological innovations have led to the development of more efficient production methods, which can potentially lower the manufacturing cost. However, these advancements often come with higher initial investment, which can impact the overall pricing structure. Additionally, the energy consumption during production, transportation, and storage also contributes to the final cost.
- Conclusion
