Based on crystallization mechanism, effective pourdepressant should meet the requirements of carbon chain matching and crystallization temperature matching.
根据共晶机理，好的降凝剂应满足碳数相匹配、结晶温度相匹配要求。

Weigang — Jingmen oil pipeline, with pourdepressant added and transportation at lower temperature, arose wax deposit, which reduced the equivalent diameter.
魏荆输油管道由于采用了加剂低温输送，致使管道管壁结蜡严重，当量管径交小。

The influence of pour point depressant on the shape and electric properties of wax crystal was studied by micro-electrophoresis meter and polarizing microscope.
