2. Pharmaceutical field:
①Carbon resin as a pharmaceutical excipient was included in the pharmacopoeia of the United States and other countries in 1957, and has been widely used in the pharmaceutical industry and other related industries.
Industry
②It is mainly used as thickening agent, suspending agent and adhesive in pharmaceuticals, as a matrix material for slow-release preparations, as a retarder, and as a film for solid preparations
Clothing materials, such as the commonly used lotion in color Doppler
3. Industrial field
Rheology modifier in water-based paint, negative electrode gel agent for alkaline batteries, gel agent in solid fuel glue, etc.
Suggest
The recommended usage is 0.2 ~ 1.0 wt%
Spread the polymer evenly in the medium while stirring, but avoid agglomeration, stir well to disperse
Neutralization to pH 5.0 ~ 10 polymer has ideal thickening performance; in a system with hydroalcohol, the neutralizer should be selected correctly;
After neutralization, avoid high-speed shearing or stirring to reduce viscosity loss
