Use gas chromatography fixed liquid (maximum operating temperature 200℃, solvent is acetone, chloroform, dichloromethane), separation and analysis of alcohol, ketone, aldehyde and other oxygen compounds, polytetrafluoroethylene water, fatty amines, volatile oil. It is widely used as a modifier for carrier and capillary column inner wall. Organic synthesis. It is used as a substrate in cosmetics, as a dispersant, lubricant, emulsifier in rubber, metal processing and other industries The medium of organic synthesis, moisturizing agent for daily cosmetics industry, inorganic salt solubilizer, viscosity regulator and other uses are used as flocculant, fluid friction reducer, textile infiltrating agent, retention and filtration aid, binder, thickener and denture fixing agent Used in cosmetics, chemical fiber, rubber, paper, paint, electroplating, metal processing and food processing and other industries Used in cosmetics industry, wood industry as moisturizer and so on Used as casting agent, metal drawing, stamping and forming lubricant, paper industry lubricant, cutting fluid, grinding liquid cooling lubrication, polishing agent, etc Used as PVC lubricant, masterbatch additive, textile softener, pigment dispersant, etc As a papermaking additive, it can improve the retention rate of fillers and fine fibers. When the relative molecular weight is more than 3 million, it has good dispersion, certain wettability, drag reduction and pyrolysis. It is an effective deflocculant. Adding into the pulping can increase the viscosity of the slurry, prevent the fiber from adhering to each other, improve the evenness of the paper, reduce the beating power consumption, and increase the physical strength.
