疏水改性羟乙基纤维素缔合增稠机理研究OA北大核心CSCDCSTPCD
Study of Thickening Mechanism of Hydrophobicly Modified Hydroxyethyl Cellulose Solutions
疏水改性羟乙基纤维素(HMHEC)通过疏水缔合与水分子有较强的相互作用,从而表现出显著的增稠增黏性、耐温耐盐性和抗剪切稳定性,作为黏度控制剂、涂料添加剂、石油开采助剂具有广泛的应用前景.今研究了HMHEC对颜料粒子CaCO3和高岭土的吸附作用机理,实验发现HMHEC对颜料粒子的吸附量随HMHEC的浓度的增大而增大,随温度和颜料粒子浓度的升高而减少;通过激光粒度仪、Zeta电位仪等测试考察了HMHEC与颜料粒子吸附前后粒径以及Zeta电位的变化情况…查看全部>>
The hydrophobicly modified hydroxyethyl cellulose (HMHEC) has high-performances of obviously increased viscosity, high temperature and salt resistances and anti-shearing stableness; all of those are because of the relatively strong interaction between the hydrophobic association and hydration. Accordingly, the HMHEC has a bright prospect of to be used as viscosity control agent, coating additive or oil exploitation additive. The mechanism of HMHEC adsorbing …查看全部>>
