我厂滚镀锌生产,原来只有两只镀缸,四只滚镀小筒,只能滚镀较小另件,牧大的另件只好吊镀,劳动强度大,生产率低。现我厂制造成功一条滚镀锌自动线,有镀槽四只,每只1 bDO公升。其中两只氨化按-氨三乙酸无氰电镀,两只碱性锌酸盐镀锌无氰电镀。每天可滚镀2万平方公寸,最高月产量45万平方公寸。 I plant rolling galvanized production, the original only two plating cylinder, four cylinder barrel plating, plating smaller pieces only, the other large pieces of animal husbandry had to hang plating, labor-intensive, low productivity. Now I plant a successful roll galvanized automatic line, a plating tank four, each 1 bDO liter. Two of them are ammoniated by cyanide-nitrilotriacetic acid plating, two of which are zinc-cyanide-free plating. Plating daily 20,000 square kilograms, the highest monthly output of 450,000 square inches.
