(high)temperature stabilizer 又称温度稳定剂。 能使钻井液在温度升高的条件下保持原有性能(主要指流变性和滤失性)稳定的添加剂。 常用的稳定剂有磺化酚醛树脂及其改性物、铬酸盐类、磺化褐煤改性物、有机磺化聚合物类、含巯基的杂环化合物类以及能防止有机物在温度升高时发生氧化降解的还原剂等。
结果表明,稳定剂能提高UP的纯度,同时对UP的高温热稳定性影响较大。
The result showed that stabilizers slightly could increased the purity and had great effect on the high-temperature thermal stability of UP.
随橡胶粉加入量的增加沥青的高温粘度将会增加,但粘度可以在加入分散稳定剂后得到改善。
As the content of rubber crumb increase the viscosity must increase too, but the viscosity could be reduced when the dispersing agent and stabilizing agent are swung in with.
同时发现,稳定剂对UP的高温热稳定性影响较大。
The stabilizers have great effect on the high-temperature thermal stability of UP.
