PDF《Tinplate and Tin Free Steel》

Printability Printing is beautifully finished using various lacquers and inks. Excellent Solderability &

Weldability TIN PLATE is widely used for making various types of cans by soldering or welding. Excellent Formability &

Strength By selecting a proper temper grade, appropriate formability is obtained for various applications as well as the required strength after forming. Beautiful Appearance Electrolytic ETP is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet. Features 产品特性

4 镀铬板特性 Features of TFS Products 优异的涂料附着力 涂料附着力远远超过镀锡板,可以用于制造 DRD 罐和胶接罐 优异的耐热变性 耐高温烘烤,不变色,材料性能不劣化 优异的抗硫化性 金属铬层有良好的抗硫化物性能,适用于富含蛋白质食物如鱼的听头 优异的耐丝状腐蚀性 漆膜下的耐丝状腐蚀能力优异 优异的耐碱性 镀铬层是非两性材料,更适用于碱性内容物如清洁剂、颜料分散剂的包装 Excellent paint adhesion TFS has excellent paint adhesion properties that far surpass those of ETP, allowing its use for making DRD cans and adhesive bonded cans. Excellent heat resistance High-temperature baking causes neither discoloration nor deterioration in material properties. Excellent resistance to Sulphur Blackening The metallic chromium in TFS has excellent sulphide resistance property when canning protein-rich foodstuff such as fish.TFS compensates for the expensive sulphur resistant lacquer. Excellent filiform rust resistance TFS has a excellent under film corrosion resistance. Excellent alkali resistance The coating in TFS is not amphoteric. Alkaline products such as detergents and dispersion colours can be packed inTFS with advantage. Features 产品特性

5 TFS 和ETP 不同特性 Different Features between TFS and ETP 外观即使使用相同表面状态的原板,TFS 的表面外观与 ETP 不同,呈现其独特的金属铬光泽. 耐蚀性 印涂后的 TFS 具有优良的耐蚀性,因此通常是两面印涂;

但依据内容物种类也可以采用罐内表面 素铁. 钎焊性 TFS 不能钎焊. 焊接性 即使去除金属镀铬层 TFS 可焊接,但焊接性差于镀锡板. 镀层重量 镀铬板一般仅有一种镀层厚度产品,而镀锡板有一系列的厚度标准. Appearance Even when the same surface finish as ETP is applied to the substrate steel sheet, it provides the unique surface luster characteristic of metallic chromium. Corrosion resistance As it has excellent corrosion resistance after painting, it is generally used with both surfaces painted. It can also be used with the internal surface unpainted, depending on the contents. Solderability TFS is not compatible with soldering. Weldability AlthoughTFS can be welded when the metallic coating layers are removed, its weldability is inferior to ETP. Coating weights Unlike the multiplicity of coating weights with tin, only one standardized chromium-coated product is manufactured.

(2) Corrosion resistance after painting is evaluated by crosshatching corrosion tests. (3) The evaluation is for the case where welding is performed without grinding the surface to remove the metallic coating layer. (4) High-temperature baking after painting and printing may cause changes in material properties. Features 产品特性
