Metil cellulos hpmc
In the paper industry, MHEC functions as a surface-sizing agent, enhancing the printability, water resistance, and strength of paper products. It also serves as a coating binder, promoting the adhesion of pigments and additives in paper coatings. Within the textile industry, MHEC assumes the role of a thickener and stabilizer in dyeing and printing processes, ensuring uniform color distribution and improved wash fastness.
Methyl hydroxyethyl cellulose (MHEC) is a kind of methyl cellulose derivative which is made from natural high polymer cellulose. It is widely used in many different industries as water retention agent, thickener, adhesive agent and dispersant etc. It could dissolve in water and form a clear solution with specific viscosity. MHEC has a good stability even though in alkaline environment and provide a good stability in heat environment. Widely used in drymix mortar industry, oil drilling, detergent and paint & costings etc.
Factors such as air temperature, temperature and wind pressure will affect the volatilization rate of moisture in cement mortar and gypsum-based products. Therefore, in different seasons, the water retention effect of the same amount of HPMC is different.
