Hydroxypropyl methyl cellulose, is a nonionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer commonly used as a lubricant in ophthalmology, or as an excipient or excipient in oral medicine.
In recent years, with the continuous development of external insulation technology, hydroxypropyl methyl cellulose production technology progress, as well as hydroxypropyl methyl cellulose HPMC itself has excellent characteristics, hydroxypropyl methyl cellulose HPMC in the construction industry has been widely used. In order to investigate the interaction mechanism between HPMC and cement-based materials, this paper focuses on the improvement effect of HPMC on the cohesion of cement-based materials.
