相信您对彩钢板并不陌生，彩涂钢板经过剪切、冲孔、弯曲、连接等工序加工而成。由于其表面有一层薄膜，应特别注意防止薄膜的损坏影响成品的外观和使用寿命。

I believe you are no stranger to color coated steel plate, which is processed through cutting, punching, bending, connecting and other processes. As there is a film on its surface, special attention should be paid to prevent the damage of the film from affecting the appearance and service life of the finished product.

1、剪切加工：剪切时应尽量减少切割段的毛刺，去除金属粉末。同时，应在下面铺设橡胶垫，以防止彩涂钢板在堆放和加工过程中损坏外观;

1. Cutting processing: when cutting, try to reduce the burr of the cutting section and remove the metal powder. At the same time, rubber pads should be laid below to prevent the color coated steel plates from damaging the appearance during stacking and processing;

2、弯曲加工：加工前应冲模、冲头等零件上的污垢和铁锈，加工过程中的温度应控制在5℃以上，如进行轧制加工，轧辊(淬火钢、模具钢等)或轧辊表面应涂上硬质材料;

2. Bending processing: before processing, the dirt and rust on stamping dies, punches and other parts should be removed, and the temperature during processing should be controlled above 5 ℃. If rolling processing is carried out, the roll (quenched steel, die steel, etc.) or roll surface should be coated with hard materials;

3、压力加工：在压力加工过程中，彩涂钢板的基板和涂层类型需要仔细选择;另外，加工要仔细，金属模具的外观要特别光滑。根据情况，彩涂钢板表面应贴养护膜，以保持涂层;

3. Pressure processing: in the process of pressure processing, the substrate and coating type of color coated steel plate need to be carefully selected; In addition, the processing should be careful, and the appearance of the metal mold should be particularly smooth. According to the situation, the surface of color coated steel plate should be pasted with protective film to maintain the coating;

4、连接：彩涂钢板可以进行机械连接、焊接连接和粘接连接，但目前彩涂钢板的焊接设备和工艺还处于研究和试验阶段，用户应尽量采用机械连接方式。

4. Connection: the color coated steel plate can be mechanically connected, welded and bonded, but at present, the welding equipment and process of the color coated steel plate are still in the research and experimental stage, and users should try to use mechanical connection.

济南彩钢板应用细则

Application rules of Jinan color steel plate

1、不同种类的面漆在硬度、柔韧性、附着力和耐久性等方面存在差异。聚酯是目前使用的涂料，具有一般的耐久性，良好的硬度和韧性，适中。硅改性聚酯具有较高的耐久性、光泽和保色性，但韧性略有下降。高耐候性聚酯具有较高的性价比。PVDF具有优异的耐久性、韧性好、硬度低、颜色少、高等优点。彩涂板面漆主要受使用、腐蚀环境、使用寿命、耐久性、加工方法和变形程度的影响。

1. Different kinds of topcoats differ in hardness, flexibility, adhesion and durability. Polyester is the currently used coating, with general durability, good hardness and toughness, and moderate price. Silicon modified polyester has higher durability, gloss and color retention, but its toughness decreases slightly. High weather resistant polyester has high cost performance. PVDF has the advantages of excellent durability, good toughness, low hardness, few colors and high price. The finish of color coated board is mainly affected by use, corrosive environment, service life, durability, processing method and deformation degree.

2、不同底漆的附着力、韧性和耐蚀性不同。环氧树脂具有良好的附着力和耐腐蚀性，但其韧性不如其它底漆。聚酯与基体的结合力好，韧性好，但耐腐蚀性不如环氧树脂。聚氨酯是一种综合性能良好的底漆。底漆通常由供应商根据生产工艺、应用、腐蚀环境以及与面漆的匹配关系来选择。

2. Different primers have different adhesion, toughness and corrosion resistance. Epoxy resin has good adhesion and corrosion resistance, but its toughness is not as good as other primers. Polyester has good adhesion and toughness with matrix, but its corrosion resistance is not as good as epoxy resin. Polyurethane is a kind of primer with good comprehensive properties. The primer is usually selected by the supplier according to the production process, application, corrosive environment and the matching relationship with the topcoat.

3、耐蚀性通常随涂层厚度的增加而增加。订购济南彩钢板时，涂层厚度应根据使用环境的腐蚀性、使用寿命、耐久性等因素确定。

3. Corrosion resistance usually increases with the increase of coating thickness. When ordering Jinan color steel plate, the coating thickness should be determined according to the corrosion of the service environment, service life, durability and other factors.
