Ацэлюлозныя эфіры HEMC для павышэння прадукцыйнасці матэрыялаў
Hydroxypropyl methyl cellulose (HPMC for short) has excellent thickening property and can be used as an excellent anti dispersion agent for concrete. In the past, this material was a fine chemical product in short supply in China, with high cost. Due to various reasons, its application in China’s construction industry was limited.
In practical construction, in the hot construction environment in summer, the water holding capacity of MHEC with the same viscosity and dosage is better than that of HPMC. Especially in the Southeast Asian countries and India, mortar will sometimes be constructed at high temperature. Cellulose ether with low gel temperature will lose its thickening and water retention at high temperature, thereby accelerating the hardening of mortar, and affects the construction.
