Put the refined cotton cellulose into the etherification kettle with the alkali liquor, add propylene oxide and methyl chloride in sequence, and etherify and wash it. Commonly known as: Industrial MSG.
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.
Construction industry: As a water-retaining agent and retarder for cement mortar, it makes the mortar pumpable. Used as a water-retaining agent in plaster, plaster, putty powder or other building materials to improve the spreadability and extend the operating time. It can be used as a paste tile, marble, plastic decoration, paste enhancer, and can also reduce the amount of cement. The water retention property of hydroxypropyl methyl cellulose HPMC prevents the slurry from cracking due to drying too fast after application, and enhances the strength after hardening.
