(1) Chemical oxidation coloring method: It is the color of the film formed by chemical oxidation in a specific solution, including dichromate method, mixed sodium salt method, vulcanization method, acid oxidation method and alkaline oxidation method. Generally, "INCO" (INCO) is used more, but if you want to ensure the same color and luster of a batch of products, you must use a reference electrode to control.
(2) Metòd koloran elektwochimik: Li se koulè fim nan ki te fòme pa oksidasyon elektwochimik nan yon solisyon espesifik.
(3) Ion depozisyon oksid metòd koloran metòd chimik: yo mete pyès la asye pur nan yon machin kouch vakyòm pou plak evaporasyon vakyòm. Pa egzanp: ka mont yo plake Titàn-yo ak espageti mont yo jeneralman jòn an lò. Metòd sa a apwopriye pou gwo -pwosesis pwodwi volim. Akòz gwo envestisman ak pri ki wo, ti pwodwi pakèt yo pa koute -efikas.
⑷ High temperature oxidation coloring method: In a specific molten salt, the workpiece is immersed in a certain process parameter, so that the workpiece forms a certain thickness of oxide film, and presents various colors.
⑸ Gas-phase cracking coloring method: It is more complicated and less used in industry.
Seleksyon metòd tretman prentan asye pur
Ki metòd yo chwazi pou tretman sifas asye pur depann sou estrikti nan pwodwi, materyèl, ak diferan kondisyon pou sifas la, epi chwazi metòd ki apwopriye pou tretman an.
