二氧化氯对部分水解聚丙烯酰胺的降黏作用

Study on reducing viscosity action of chlorine dioxide in HPAM solution

研究了二氧化氯对部分水解聚丙烯酰胺(HPAM)的降黏作用,探讨了pH值、温度及其他氧化剂及复配体系对黏度的影响及其降黏作用机理。结果表明,pH值对HPAM黏度的影响较大,复配硫酸亚铁或过氧化氢可明显降低黏度。提出了水解反应和氧化反应都是引起HPAM溶液黏度大幅下降的原因。

The changes in viscosity were studied when ClO2 was added into the Partially hydrolyzed polyacrylamide（HPAM）solution. A remarkabal decrease in the solution viscosity of HPAM polymer was observed with decreased pH, elevated temperature and addition of FeSO4 or H2O2. The viscosity reduction of HPAM involves two main reactions： oxidation and hydrolysis.
