彩钢板板材使用特点都有哪些？

近年来，随着建材市场的发展，彩钢板的使用越来越广泛，这在我们的日常生活中很普遍。其美观、方便的特点深受消费者的喜爱。很多人选择购买它，而且分析它的特点很方便。现将其详细介绍如下。

1. 彩钢板底部可生产镀锌钢板。有机涂层具有良好的耐腐蚀性，但有机涂层也可放入空气和水中，使其基材生锈，无法使用。因此，它不能由无涂层的彩色基材钢制成。其寿命短，不能使用。彩钢基材主要为镀锌钢或镀锌合金钢。
2.彩色涂装工艺分为基材预处理、化学转化膜（非有机金属涂装）、有机非金属涂装等，以及消费品线涂装工艺。
3.基材处理前：如果作为基材的镀锌钢板在彩色涂装过程中不直接消耗，则在运输过程中可能会产生锈（锈）、灰尘等污染。如果不清除这些污染，颜色的质量和效果就会受到影响。废物的质量及其所有物理和化学性质与预处理密切相关。
4. 彩钢板化学转化膜：它有两个功能：一是进一步改善腐蚀，二是改善基材与涂层之间的附着力，提高基材的涂层性能。一般有三个步骤：一是磷化，首先在金属表面形成大量晶体，然后用磷盐溶液在金属表面形成磷化膜；第二，钝化和密封。磷化膜上仍有一些孔，这些孔与铬酸盐和孔点发生化学反应，形成维护膜。3、 用纯水冲洗，并用盐或去离子水钝化液体。
5.有机涂料：有机涂料分为底漆和面漆。底漆要求不高，可以使用油漆，但现在已经消耗掉了，底漆和面漆一般都是反涂的。后涂工艺：后涂工艺包括印刷、压花、剥离保养膜、贴膜等，以提高同心彩钢板的装饰保养性能。此外，一些国外的涂层工艺在冷轧后被整平和矫直，并在镀锌过程中磨损。

In recent years, with the development of the building materials market, the use of color steel plate is more and more widely, which is common in our daily life. Its beautiful and convenient characteristics are very popular among consumers. Many people choose to buy it, and it is convenient to analyze its characteristics. Now it is introduced in detail as follows.

1. Galvanized steel plate can be produced at the bottom of color steel plate. Organic coating has good corrosion resistance, but organic coating can also be put into air and water to make its substrate rusty and can not be used. Therefore, it can not be made of uncoated color substrate steel. Its life is short and can not be used. The color steel base material is mainly galvanized steel or galvanized alloy steel.
2. The process of color coating is divided into pretreatment of substrate, chemical conversion film (non-organic metal coating), organic non-metal coating, etc., as well as the process of consumer line coating.
3. Before substrate treatment: if the galvanized steel plate as the substrate is not directly consumed in the color coating process, rust (rust), dust and other pollution may be generated during transportation. If these pollution are not removed, the quality and effect of color will be affected. The quality of waste and all its physical and chemical properties are closely related to pretreatment.
4. Chemical conversion film: it has two functions: one is to further improve the corrosion, the other is to improve the adhesion between the substrate and the coating and improve the coating performance of the substrate. There are generally three steps: first, phosphating, first form a large number of crystals on the metal surface, and then form a phosphating film on the metal surface with phosphorus salt solution; Second, passivation and sealing. There are still some holes in the phosphating film, which react chemically with chromate and pore points to form a maintenance film. 3、 Rinse with pure water and passivate the liquid with salt or deionized water.
5. Organic coatings: organic coatings are divided into primer and finishing coat. The requirements for primer are not high, and paint can be used, but now it is consumed, and the primer and finish paint are generally reverse coated. Post coating process: the post coating process includes printing, embossing, stripping maintenance film, film, etc., so as to improve the decorative maintenance performance of concentric color steel plate. In addition, some foreign coating processes are leveled and straightened after cold rolling and wear out in the course of galvanizing.
