弯曲试验:是衡量薄板工艺性能的重要项目。然而,不同国家的镀锌钢板的吸引力不同。弯曲180°后,外侧锌层不应分离,板底无裂纹、断裂。
6化学成分
对于镀锌基材的化学成分,不同国家有不同的标准。如果日本不申辩,美国会申辩。普通产品未经检验。
7板形
衡量黑白的形状有两个目的,即直线度和镰刀弯曲度。定义了钢板的平面度和镰刀弯曲的大允许值范围。
热镀锌钢板的优点是耐腐蚀性好、涂装性好、装饰性好、成形性好。近年来,汽车用热镀锌钢板数量不断增加,已成为汽车板的主体。世界上许多国家都在探讨如何扩大热镀锌钢板的品种和规格,改进镀层工艺,进而提高镀层质量,即耐蚀性、抗粉化性、镀层性和可焊性。涂层板的成形性一直是其应用的一个重要方面,它主要取决于基体性能、涂层工艺和性能以及成形工艺条件。只有经过全面的先进技术配套,才能取得良好的应用效果。

Bnding experiment: it is an important item to weigh the technological function of thin plate. However, the appeal of various galvanized steel sheets in different countries is different. After bending for 180o, the zinc layer on the outside shall not be separated, and the plate base shall not be cracked or broken.

6. Chemical composition
For the chemical composition of galvanized substrate, different countries have different standards. If Japan does not plead, the United States does. Ordinary products are not inspected.
7. Plate shape
There are two purposes to weigh the shape of black and white, namely straightness and sickle bend. The flatness of the plate and the large allowable value scale of sickle bend are defined.
The advantages of hot-dip galvanized steel sheet are excellent corrosion resistance, painting, decoration and good formability. In recent years, the amount of hot-dip galvanized steel sheet in automobile is increasing, and it has become the main body of automobile sheet. Many countries in the world are discussing how to expand the types and specifications of hot-dip galvanized steel sheet, improve the coating process, and then improve the coating quality, that is, corrosion resistance, resistance to powdering, coating and weldability. The formability of coated sheet has always been an important aspect of its application, which mainly depends on the substrate performance, coating process and performance and forming process conditions. Good application effect can only be achieved after comprehensive advanced technology matching.
