grp platform steps

Once purified cellulose is obtained, the next stage involves the etherification reaction, which is central to the production of HEC. In this process, the purified cellulose is treated with ethylene oxide, a chemical compound that reacts with the hydroxyl groups present in the cellulose structure. This reaction occurs in a controlled environment, often using solvents and catalysts to facilitate the process. The temperature and pressure during this stage are critical parameters, as they directly influence the degree of substitution of the hydroxyethyl groups on the cellulose backbone. An optimized reaction conditions ensure that the HEC produced has the desired viscosity and solubility characteristics.

In order to improve the redispersibility of redispersible polymer powder and prevent caking during drying and storage, protective colloids or surfactants (emulsifiers) should be added before drying, making the redispersible polymer powder with strong hydrophilicity and alkali sensitivity. The most commonly used protective colloid is partially hydrolyzed polyvinyl alcohol (PVA). PVA contains a lot of hydroxyl groups, with quite poor water resistance. And the vinyl acetate polymer itself is poor in the water resistance, especially hot water resistance, due to its polar ester and carboxyl groups. In the redispersible polymer powder containing PVA and carboxyl groups, polyvalent metal salts can be added to improve its water resistance, especially hot water resistance, since PVA and carboxyl groups can react with metal salts to become insoluble in water. In the emulsion containing PVA, aldehydes can also be added for PVA acetalization and then to reduce its water absorption. In addition to PVA, some other protective colloids with good water resistance can also be selected to ensure the water resistance of product, such as polyacrylic acids and modified polyacrylic acids.

HPMC powder is a white, odorless, and tasteless powder that is soluble in water. It forms a viscous gel when mixed with water, making it an effective thickening agent.
