自70年代初,含有有机添加剂的碱性镀锌工艺问世以来,为了提高镀锌层的外观质量,人们的研究重点逐渐转向优质高效的有机光亮剂。诸如:香草醛、茴香醛、对羟基苯甲醛、EDTA、WA、WB、ZB-81等。就综合效果来看,香草醛是较为可取的,是一种颇受欢迎的光亮剂。然而也还存在着一些不尽人意的地方,如价格贵、货源不足、尚属通用品等。 Since the early 70s, alkaline zinc plating process with organic additives has come out, in order to improve the appearance quality of galvanized layer, people’s research focus gradually shifted to high quality and efficient organic brightener. Such as vanillin, anisaldehyde, p-hydroxybenzaldehyde, EDTA, WA, WB, ZB-81 and the like. On the combined effect of view, vanillin is more desirable, is a popular brightener. However, there are still some unsatisfactory places, such as the price is expensive, lack of supply, is still a generic product.
