HPMCの密度は、温度や湿度などの環境条件にも影響されるため、実験室での正確な測定が求められます。特に、製品の均一性と性能を保証するためには、密度の管理が重要です。また、HPMCは水分を吸収しやすく、使用する環境によってはその特性が変わるため、密度測定は定期的に行うことが推奨されます。
hpmc densityAt low concentrations, HEC solutions exhibit Newtonian behavior, where the viscosity remains constant regardless of the shear rate applied. However, as the concentration increases, the behavior of the solution transitions to non-Newtonian, displaying shear-thinning properties. This means that as shear is applied (for example, during mixing or pumping), the viscosity decreases, facilitating easy processing. This characteristic is particularly advantageous in industries like construction, where HEC-based slurries can be easily applied and spread before setting.
