摘要
用裂解质谱的方法对美国HTI公司三种正渗透膜CTA-ES、CTA-NW和TFC-ES的成分进行了鉴定,并且利用扫描电子显微镜(SEM)对其结构进行了仔细的观察。结果显示,三种膜都是由醋酸纤维素、聚酯、聚砜、聚氨酯等高分子材料组成的层状结构。
The analysis of the composition and structure of these three membranes from American HTI Company was introduced simply. Specially, the composition of the three membranes was identified by the method of pyrolysis mass spectrometry and the structure of them was observed carefully using scanning electron microscope. The results reveal that these three membranes are all layer structure and made from polymer materials of cellulose acetate and polyester, polysulfone, polyurethane.
