本文介绍了乳化液的再乳化以及破乳剂表面张力与脱水效果的关系。实验结果表明:再乳化可使破乳剂的脱水效果变差,而破乳剂的表面张力则与脱水效果关系不大。 This article describes the re-emulsification of emulsion and demulsifier surface tension and dehydration effect. The experimental results show that re-emulsification can dewate the dewatering effect worse, while the surface tension of the demulsifier has little to do with the dehydration effect.
