Anionic electrodeposit coating line for aluminum shell of solar water heater is introduced.Anodic oxidation,anodizing electrolytic coloring and anionic electrodeposit coating process are focused.
Neodymium is a bright, silvery rare-earth metal element, found in monazite and bastnaesite and used for coloring glass and for doping some glass lasers.
The coloring matter are separated by YWG-C18,the best wave is found by DAD detecter, the quantitative method is standard curve , the result is accurately ,the method are used simply.
