摘要:

管道内壁面涂敷一层亲水／疏油的光滑涂层，可防止蜡的附着。

Abstract:

A smooth hydrophilic/oleopholic coating on the inner pipeline can prevent paraffin adher adherence. The contact angle between coating and liquid paraffin is effected by the chemical structure of coating surface. The wettability between coating and oil is
