研究了固相法CIPP的稀溶液和浓溶液性能 ,结果表明 ,随着氯含量的增加CIPP稀溶液的特性粘数和浓溶液的粘度都呈下降趋势。溶液粘度随氯化反应温度的升高上升较快 ,在力化学降解下CIPP的溶液粘度下降较快。CIPP固含量超过 2 0 % ,粘度上升较快
The properties of dilute solution and concentrated solution of CIPP were studied. The results showed that the inherent viscosity of CIPP dilute solution and the viscosity of concentrated solution all decreased with the increase of chlorine content. The viscosity of the solution increased rapidly with the increase of the temperature of the chlorination reaction, and the solution viscosity of CIPP decreased rapidly under the condition of chemical degradation. CIPP solid content of more than 20%, the viscosity increased rapidly
