폴리카복실산계 감수제의 복합 방법
Compound method of Polycarboxylic Acid Superplasticizer agent 1. Compound with traditional water reducer The molecular structure of polycarboxylic acid water-reducing agent is artificially designed, and it is mostly “comb” or “dendritic”. Its molecular main chain is connected with multiple branches with a certain length and rigidity. The sulfonate or other groups that charge the cement particles, […]
온도가 하이드록시프로필메틸셀룰로오스(HPMC)의 수분 보유력에 미치는 영향
The effect of temperature on the water retention of Hydroxy Propyl Methyl Cellulose (HPMC) 1. Cellulose ether HPMC thermal gel temperature The high temperature of thermal gel, high water retention; on the other hand, the water retention rate is low. 2. Viscosity of cellulose ether HPMC When the viscosity of HPMC increases, the water retention rate also increases; […]
