Henan Tianhe explain how to choose a suitable hydroxypropyl methylcellulose

The main raw materials are hydroxypropyl methylcellulose hydroxypropyl methyl refined cotton, methyl chloride, propylene oxide, as well as other raw materials, caustic soda, acid, toluene, isopropanol different viscosities of different areas of application cellulose HPMC, hydroxypropyl currently mainly used in more putty powder and mortar, putty powder desired viscosity methyl cellulose is not high, usually thousands of it, because the quality of the cellulose product now uneven, miserable fake a lot, choose good quality cellulose is more difficult, in fact, putty powder, as long as good water retention, low viscosity of these are possible, probably seven or eight million have been able to meet the requirements of the . Building mortar inside seeks higher, at least one hundred and fifty thousand to go with a viscosity of cellulose, polystyrene particles mortar demanding the best choice for two hundred thousand viscosity. In fact, we are most concerned about is nothing more than hydroxypropyl methyl cellulose content and viscosity of these two indicators, water retention is good or bad depends on the level of hydroxypropyl content, viscosity, and relatively speaking, water retention is better, and on the viscosity of the cement mortar in better use some. Therefore, according to the actual situation of their products to choose not viscosity higher the better, but for the best. Through the above narrative, whether you hydroxypropyl methyl cellulose we have a deeper understanding of it? I hope this information can help a friend in need.
