Hydroxypropyl methylcellulose is made from highly pure cotton cellulose through special etherification under alkaline conditions, and the whole process is completed under automatic monitoring. It is insoluble in ether, acetone and absolute ethanol, and swells into a clear or slightly cloudy colloidal solution in cold water. The aqueous solution has surface activity, high transparency and stable performance. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water-retaining performance of hydroxypropyl methyl fiber prevents the slurry from cracking due to too fast drying after application, and enhances the strength after hardening.
With the decrease of methoxyl content, the gel point increases, the water solubility decreases, and the surface activity also decreases. The product also has the characteristics of thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and wide range of enzyme resistance, dispersibility and cohesiveness.
It is used as a thickener, dispersant and stabilizer in the paint industry, and has good compatibility in water or organic solvents. As a paint remover. It is used as a thickener, dispersant and stabilizer in the ink industry, and has good compatibility in water or organic solvents. This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industries
