泵送性

半结晶OCP在较低温度下产生胶冻，在用油低温性能泵送性差，易造成供油不足导致早期磨损。

Gel , which is formed in the oil blended by semi-crystalline OCP under low temperature , will result in the poor low temperature pumpability , and the wear will occur easily in the first run duration .

其它特性包括出色的水污染忍受性和抗高温氧化能力用于换油中心的泵送设备亦展示出良好的泵送性。

Other formulation characteristics include superior water tolerance , high temperature oxidation resistance , and good pumpability by service station dispensing systems .

该堵剂用调节pH值及变化配方等方法，在70～130℃下可控制成胶时间，在成胶前有较好的泵送性和在孔隙中的滞留能力。

Through the means of pH adjusting and formula modification , the time for gel formation can be controlled under the temperature of 70 ￣ 130 ℃ . It has favorable pumping ability and retention ability in pores .
