Color steel plate is based on cold-rolled steel plate and galvanized steel plate, otherwise, due to the effect of sulfur dioxide gas, salt and dust, it will affect the use. Therefore, in the design, if the inclination of the roof is large, it is not easy to scale and other dirt, and the service life is long; for those areas or parts that are not often washed by rain, the strip steel shall be washed with water regularly on the continuous unit for cold rolling. As the coating is before the steel plate forming and processing, it is called precoated steel plate in foreign countries.

工艺流程:

technological process:

经过表面预处理(脱脂、清洗、化学转化),连续涂有油漆的方法(辊涂方法),除了有保护锌,锌层上的有机涂层覆盖隔离功能,可以防止钢铁生锈,更长使用寿命比镀锌钢板,钢板上的涂层的使用寿命长于镀锌钢的50%。

After surface pretreatment (degreasing, cleaning, chemical conversion treatment), the method of continuous painting (roller coating method), in addition to the protection of zinc, the organic coating on the zinc layer covers the isolation function, which can prevent steel from rusting, and the service life of the coating on the steel plate is longer than that of the galvanized steel plate, and the service life of the coating on the steel plate is 50% longer than that of the galvanized steel.

但是，在不同地区和不同部位使用时，用同样数量的镀锌，同样种类的镀层，同样厚度的彩色镀锌板，其使用寿命会有很大的不同。例如，在工业区或沿海地区，腐蚀速度加快，空气中的二氧化硫气体或盐影响使用寿命。在雨季,涂层很长一段时间被雨水浸泡,经过烘烤和冷却产品的镀锌带钢(电镀锌和热镀锌)为基板,经过表面预处理(脱脂和化学处理),用辊涂的方法,涂上一层或多层液态涂料,经过烘烤和冷却板涂层钢板。因为涂料可以有多种颜色，

However, when it is used in different areas and different parts, the service life of color galvanized sheet with the same amount of zinc plating, the same kind of coating and the same thickness will be very different. For example, in industrial areas or coastal areas, the speed of corrosion is accelerated, and sulfur dioxide gas or salt in the air will affect the service life. In the rainy season, the coating is soaked by rainwater for a long time. The galvanized strip steel (electro galvanized and hot galvanized) of baked and cooled products is used as the base plate. After surface pretreatment (degreasing and chemical treatment), one or more layers of liquid coating are applied by roller coating, and then the coated steel plate is baked and cooled. Because paint can have many colors,

普通双涂层双干燥连续彩色涂层机组的主要生产工艺为:开卷→预处理→涂覆→烘烤→后处理→缠绕。

The main production process of common double coating and double drying continuous color coating machine is: uncoiling → pretreatment → coating → baking → post-treatment → winding.

Product usage:

涂层钢板有光,美丽和良好的防腐蚀性能,并且可以直接处理,它提供了一个新的建筑行业的原材料,造船行业、汽车制造行业、家具行业、电子行业,等等,来代替木材和钢铁、的建设、、污染防治等良好效果。

Coated steel plate has bright, beautiful and good anti-corrosion performance, and can be directly treated. It provides a new construction industry of raw materials, shipbuilding industry, automobile manufacturing industry, furniture industry, electronic industry, etc., to replace wood and steel, efficient construction, energy saving, pollution prevention and other good effects.

采用镀锌钢板为基材的彩涂钢板，或在昼夜温差太大的地方容易结露的部位，会很快被腐蚀，使用寿命会降低。

The color coated steel plate with galvanized steel plate as the base material, or the part where the temperature difference between day and night is too big and easy to condense, will be corroded quickly and the service life will be reduced.
