Production process
Raw material preparation: Select high-quality cotton pulp or wood pulp and treat it with alkali to form alkali cellulose.
01
Etherification reaction:
Alkali cellulose is reacted with methyl chloride and propylene oxide.
The etherification reaction is carried out under controlled temperature and pressure to produce HPMC.
02
Neutralization washing: remove by-products and unreacted substances after the reaction is completed
03
Drying and crushing: After drying, screening and other steps, HPMC products with different viscosity grades are obtained.
04
Packaging, storage and transportation: Finished products are packaged according to specifications.
05
Performance characteristics
Thickening property
HPMC has excellent water solubility and high thickening ability. Its solution has good rheological properties, which can give the product the required viscosity and thixotropy.
Water retention
It can effectively prevent water loss and improve working performance in formulations such as building mortar and paste-like medicines.
Film-forming property
After drying in aqueous solution, it can form a tough and transparent film, which is widely used in pharmaceutical coating and daily chemical film products.
Suspension and emulsification
It has good dispersing and emulsifying capabilities and is suitable for use in emulsion products and drug suspensions.
Gel properties
It has thermal gel properties, turning into gel when heated and turning into solution after cooling
