影响聚丙烯酸盐增稠性的因素

FACTORS INFLUENCING THE THICKENING ABILITY OF POLYACRYLIC ACID SALT (PAAS)

研究了影响聚丙烯酸盐(PAAS)增稠剂增稠性的因素。随乳化剂用量的增加 ,PAAS水增稠体系的触变指数和增稠性都增大;随反应温度的提高 ,PAAS水增稠体系的触变指数和增稠性都减小;随引发剂用量的增加 ,PAAS水增稠体系的触变指数和增稠性先增大 ,用量为2‰时达到最大值 ,过后下降。

Factors influencing the thickening ability of PAAS thickening agent was researched, the thixotropic factor and thickening ability of aqueous PAAS thickening agent increased with increase of emulsifier, decreased with increase of reaction humidity, and first increased with increase of initiator, reached the maximum when the dosage of initiator is 2‰, and then began to decline.
