彩色涂层钢板相关知识介绍

彩涂钢板是一种以冷轧板带为涂层,以镀锌板带(镀锌和热镀锌)为基板,经表面预处理(脱脂和化学处理)、滚涂、一层或多层液体涂层、烘烤和冷却而成的钢板。因为涂料可以有不同的颜色。

彩色涂层钢板相关知识介绍

采用彩涂钢板的优点:彩涂钢板:由于彩涂钢板的生产工艺受到严格控制,在外观、耐久性和加工性方面保证了质量的均匀性。大量生产的涂层钢板价格低廉。与产品的涂层处理方法相比,涂层钢板固含量高,有机涂层损耗低,经济性好。
涂层钢板的应用可以大大简化加工工艺,不存在化学处理、涂装、烘烤等对环境造成的污染。一般选用的涂料有环氧、聚酯、硅改性聚酯、聚偏氟乙烯、聚氨酯等。我们将根据不同的应用环境和用途进行选择。
选用不同基材或涂层的彩涂钢板外用。应选择带有彩色涂层钢板的热浸镀锌基板。镀锌钢板的数量通常超过180 g/m(双面)。聚偏氟乙烯涂料应选择光和颜色保持10至20年。

在施工中用作瓦楞纸板时,最好选用上下表面均涂2层、2次烘烤的彩涂钢板。制作夹芯板时,上表面作两层涂料。本实用新型重量轻、美观、防腐性能突出,可直接加工。因此,它可以广泛应用于建筑业、造船业、汽车制造业、家具业和电器业。工业等

Coloured steel sheet is a kind of steel sheet which is coated with cold rolled strip and galvanized strip (galvanized and hot galvanized) as its base plate. It is prepared by surface pretreatment (degreasing and chemical treatment), rolling coating, one or more layers of liquid coating, baking and cooling. Because paints can have different colors.
The advantages of using color coated steel plate: color coated steel plate: because the production process of color coated steel plate is strictly controlled, the uniformity of quality is guaranteed in appearance, durability and workability. Coated steel plates produced in large quantities are inexpensive. Compared with the coating treatment method, the coated steel plate has higher solid content, lower loss of organic coating and better economy.
The application of coated steel sheet can greatly simplify the processing technology, and there is no environmental pollution caused by chemical treatment, coating, baking, etc. Generally selected coatings are epoxy, polyester, silicon modified polyester, polyvinylidene fluoride, polyurethane and so on. We will choose according to different application environments and uses.
Colored coated steel plates with different substrates or coatings are selected for external use. Hot dip galvanized substrates with color coated steel sheets should be selected. The number of galvanized steel sheets usually exceeds 180 g/m (double sided). Polyvinylidene fluoride paint should choose light and color to keep for 10 to 20 years.
When used as corrugated cardboard in construction, it is better to use two-layer and two-time baked color-coated steel plate on both upper and lower surfaces. When making sandwich panels, the upper surface is coated with two coatings. The utility model has the advantages of light weight, beautiful appearance, outstanding anti-corrosion performance, and can be directly processed. Therefore, it can be widely used in the construction industry, shipbuilding industry, automobile manufacturing industry, furniture industry and electrical industry. Industry, etc.
