First, China has a lot of sealant manufacturing plant, its formulation are similar to the products of the United States of Grace, will not have a lot of tin cans differences in performance. Therefore, to ensure the sealing quality cooperage (cans), might as well focus mostly concentrated on sealing material and design of the wheel is more important than the sealant. If the traditional size: 512 × 712m / m calculation 0.2m / m thickness of iron per ton tinplate is 1750, 0.23m / m thickness of iron per ton is 1520, with 0.20m / m of iron instead of 0.23m / m iron production barrel (tank), in terms of the price of 5,500 yuan / ton, 825 yuan savings.
Second, paint and ink for the low tin amount of iron and plated ferrochrome is very important, not good paint and ink there can be the low tin iron or plated ferrochrome actual value in use.
Three thick thin-generation: the pursuit of our application history, hot dip metal products 50 to be used in the 1960s, the tin layer # 100; 1970s tinplate sheet electrolytic tinplate, tin-plated layer is 50 # -100 #; 1990s tin layer thin, respectively, 10 # low tin iron and chrome iron. In addition to the tin layer with a thin substituting thick on the substrate more articles do. ORG is now in the production of tomato sauce cans, which is resistant to corrosion by high acid food cans, of coatings must use the acid-resistant epoxy phenolic coatings, coating technology and coating thickness must be strictly controlled in order to ensure the coating the denseness of the film, as well as the balance of the corrosion resistance and adhesion.
Fumo iron: Fumo iron completely tin, plastic film tinplate coil directly after a special melting process closely fit the surface of the sheet steel with paint tinplate can not match the excellent anti-corrosion and cooperage (tank) performance, is a promising new type of cooperage material (cans), two cans instead of three cans of food or beverage cans made ??of it.
