1.The conversion film is probably constituted of amorphous and pored alloying tannate chelate.
这种转化膜很可能是由有一定孔隙的非晶态金单宁酸膜层构.
2.In this paper, the new chelating resin (PSIM) with a polythioether backbone bearing imidazole group is first synthesized by the reaction between polychloromethylthiirane and imidazole.
通过聚环硫氯丙烷与进行高分子反应,了以聚硫醚为主链、侧链带有基团的螯树脂(简称PSIM)。
3.3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.
