摘要纤维素醚改性石膏在不同环境温度下的工作性能有很大差异,但其作用机理还不明确。研究了不同环境温度下纤维素醚对石膏浆体流变参数和保水性的影响,并通过动态光散射法测定了纤维素醚在液相中的流体力学直径,探究了其影响机理。结果表明纤维素醚对石膏有着良好的保水增稠效果,随着纤维素醚掺量的增加,浆体粘度增加、保水性提高,但是随着温度的升高改性石膏浆体的保水性有一定程度的降低,各项流变参数也发生改变。考虑到纤维素醚胶体缔合物可通过阻塞水分传输通道以实现保水,温度升高可能导致纤维素醚产生的大体积缔合物解体,从而使改性石膏的保水性降低、工作性变差。

Abstract: The working performance of cellulose ether modified gypsum varies greatly at different ambient temperatures, but its mechanism of action is still unclear.In this paper, the effect of cellulose ether on the rheological parameters and water retention of gypsum slurry under different ambient temperatures was studied, and the hydrodynamic diameter of cellulose ether in the liquid phase was measured by dynamic light scattering method, which revealed its influence mechanism. The results show that cellulose ether has a good effect on water retention and thickening. The water retention and viscosity of gypsum slurry increase with the increase of the content. The higher viscosity of HPMC, the better thickening effect. With the increase of temperature, the water retention of the modified gypsum slurry has a certain degree of reduction and the rheological parameters varied a lot. Considering that the cellulose ether colloidal association can block the water transmission channel to achieve water retention, the increase in temperature may cause the disintegration of the bulky association produced by the cellulose ether, thereby reducing the water retention of the modified gypsum and workability.

Key words: gypsum cellulose ether temperature water retention rheology
