Cellulose ethers are an important class of commercial water-soluble polymers used in construction and construction industries. Cellulose ethers can increase the viscosity of aqueous media. The viscosity-increasing ability of cellulose ether is mainly controlled by its molecular weight, the chemical substituents attached to it, and the conformational characteristics of the polymer chain. Methyl cellulose (MC), methyl hydroxyethyl cellulose (MHEC), ethyl hydroxyethyl cellulose (EHEC), methyl hydroxypropyl cellulose (MHPC), hydroxyethyl cellulose (HEC), Hydrophobically modified hydroxyethyl cellulose (HMHEC) alone or in combination is the most widely used cellulose ether in mortar formulations.
The most important properties of cellulose ether polymers include:
Good thickening / thickening efficiency
Available in a wide range of molecular weight and viscosity
Excellent properties as a water-retaining agent
Excellent resistance to dissolved inorganic salts
Excellent solution clarity
Low toxicity and environmental protection
Methyl hydroxyethyl cellulose ether(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 have 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.
