| 聚丙烯纤维是一种良好的吸油材料。它具有吸油率高和吸油速度快的优点。将它装入油膜采集器,可以吸收漂浮于水面上的同面积的油膜。聚丙烯纤维在吸油的同时,也能吸收一部分水,用3A型的分子筛将水吸出,即可得到吸收的油重。用该方法可以较准确地测定漂浮于水面上的油膜重量和厚度。 |

| DETERMINATION OF OIL WITH POLYPROPYLENE-MOLECULAR SIEVE |
|
|
| Abstract: |
| Polypropylene fiber is a good material for absorbing oil (Fig.). The oil film sampler with the polypropylene fiber in has a definite diameter, therefore, can absorb the same area of oil film drifting on the water surface. It can absorb also water after absorbing oil. The water absorbed by the polypropylene is again absorbed out by 3A molecular sieve, thus the weight of oil film absorbed can be known. This is an accurate and reliable method determining the oil film weight and thickness. |
