作为卷材连续生产的工艺办法,镀锌板能够分为电镀锌和热镀锌两种办法,其间电镀锌办法是用电堆积的办法使金届衷画镀上-"zn金属或zn合金。热镀锌也叫做热浸镀,是将被维护金属制品浸渍在熔融的zn金属中,使其外表构成一层维护性金属覆盖层。与电镀法比较,金属热镀层较厚;在相同环境下,其寿数较长。使用镀锌钢板为基板的彩色涂层钢板,除有锌保护外,锌层上的有机涂层起了覆盖隔离作用,可防止钢板生锈,使用寿命比镀锌钢板更长,据了解涂层钢板的使用寿命比镀锌钢50%但是,在不同的地区和不同的使用部位,采用相同镀锌量、同种涂料、相同涂层厚度的彩色涂层板,其使用寿命会有很大的不同。例如,在工业区或沿海地区,由于受到空气中二氧化硫气体或盐分的作用,腐蚀速度加快,使用寿命受到影响。在雨季,涂层长期受雨水浸湿、或者在日夜温差太大易结露的部位,都会较快地受到腐蚀,使用寿命会低。

As the process method of continuous production of coil, galvanized plate can be divided into two methods of galvanizing and hot galvanizing, during which galvanizing method is the method of electricity accumulation to make the gold session of the painting plating- " layer zn metal or zn alloy.Hot dip galvanizing, also known as hot dip plating, is the dip of maintenance metal products in molten zn metal to form a maintenance metal cover layer.Compared with plating, metal hot plating is thicker; longer in the same environment.The use of galvanized steel plate as the substrate color coated steel plate, in addition to zinc protection, the organic coating on the zinc layer plays a cover isolation effect, can prevent steel plate rust, service life is longer than galvanized steel plate, it is understood that the service life of coated steel plate is 50% longer than galvanized steel plate.However, in different areas and different use parts, the use of the same galvanizing amount, the same coating, the same coating thickness of the color coating plate, its service life will be very different.For example, in industrial areas or coastal areas, the corrosion rate is accelerated due to the action of sulfur dioxide gas or salt in the air.In the rainy season, the coating is wet by rain for a long time, or in the temperature difference between day and night is too large to dew, will be corroded quickly, the service life will be low.
