复合聚丙烯板在油水分离中的应用

采用化学改性处理的方法，使聚丙烯表面覆盖一层氧化薄膜，从而改善聚丙烯的亲水性。基于聚丙烯本身良好的亲油性，开发出两表面分别具有良好亲油、亲水性能的复合型聚丙烯板。这种复合型聚丙烯板应用于聚结板式油水分离器，迎合了油水分离机理，强化了油水分离过程。实验结果表明，复合聚丙烯聚结板使油水分离器的分离效率提高了25％，分离器的处理能力提高了40％。

Application of Polypropylene Composite Plate in Oil-Water Separation

A thin layer of oxidizing membrane was obtained on the surface of polypropylene by means of chemical modification.This layer is effective on improving the hydrophilicity of the material surface.And polypropylene itself is a typical hydrophobic material,so a polypropylene composite plate with one side hydrophobic and the other hydrophilic can be developed.Application of this composite plate in coalescing oil-water separator caters for the mechanism of oil-water separation, and makes an enhancement on separating process.The experimental results show that with this composite coalescence-plate,the separation efficiency and the capability of the equipment are enhanced by 25 % and 40 % respectively.
