摘要:
A gas cylinder is coated on its internal, gas-contacting surface with a polar film-forming polymer, such as poly(vinyl alcohol), whereby non-polar organic molecules will not adhere to the polymer film. The coating greatly increases the stability of gases stored in the cylinder, which is particularly useful in storing gas mixtures used for gas calibration methods.
摘要(中):
在其内部气体接触表面上用气体接触表面涂覆聚(乙烯醇)等极性成膜聚合物,由此非极性有机分子不会附着在聚合物膜上。 涂层大大增加了储存在气瓶中的气体的稳定性,这对储存用于气体校准方法的气体混合物尤其有用。
