随着钢板市场的不断发展壮大,彩钢板材的使用范围变得也越来越广泛,济南彩钢板在我们的日常生活中十分常见,因其具有美观、使用方便等优势特点深受消费者的喜爱,吸引了许多人前来选购,下面为大家分析一下它的特点方便大家选购。
With the continuous development of the steel plate market, the use range of color steel plate has become more and more extensive. Jinan color steel plate is very common in our daily life. Because of its beautiful, easy-to-use and other advantages, it is deeply loved by consumers and attracted many people to come to choose and buy. Here is to analyze its characteristics for you to purchase.
彩钢板
Color steel plate
1、彩钢板的基材能够选用冷轧板或热镀电镀层钢材,固然彩钢板的有机涂层局部有很好的防腐蚀作用,但有机涂层中仍有一些小的空隙,能够让空气及水份都可能进入进,使其基材生锈,不能用,所以采用无镀层的基材做成的彩钢板,运用寿命短,且划伤后很容易扩散,招致涂层剥落。彩钢板的基材以镀锌钢板或镀锌合金钢板为主。
1. The base material of color steel plate can be cold-rolled plate or hot-dip electroplated steel. Although the organic coating of color steel plate has a good anti-corrosion effect, there are still some small gaps in the organic coating, which can make the air and water enter into the steel plate, so that the substrate rust and can not be used. Therefore, the color steel plate made of uncoated substrate has a short service life and is easy to scratch Diffusion, resulting in coating spalling. The base material of color steel plate is mainly galvanized steel plate or galvanized alloy steel plate.
2、彩涂的消费程序分为基材的前处置,化学转化膜(非有机金属涂层),有机非金属涂层,另外有些消费线还有涂后工艺。
2. The consumption process of color coating is divided into pretreatment of substrate, chemical conversion coating (non organic metal coating), organic non-metallic coating, and some consumption lines have post coating process.
3、基材前处置:作为基材的镀锌钢板假如不是在消费后直接进入一道彩涂工序,则可能会在运输过程中呈现锈蚀(白锈),灰尘,及其他污染。假如不能把这些去掉,则会影响彩涂的质量和效果。废品的质以及一切物理、化学性能都与前处置有亲密关切。另外,在镀锌消费后,为了防锈而涂油,这些油也是要在彩涂消费行进行准备的,如今运用较多的前处置办法为碱溶液脱脂法。
3. Pre treatment of substrate: if galvanized steel sheet as substrate is not directly into a color coating process after consumption, it may present rust (white rust), dust, and other pollution during transportation. If you can't get rid of these, it will affect the quality and effect of color coating. The quality of waste products and all physical and chemical properties are closely concerned with pre disposal. In addition, after galvanizing consumption, oil is applied to prevent rust. These oils are also prepared in the color coating consumer line. Nowadays, the alkali solution degreasing method is widely used.
4、化学转化膜:作用有二,一是进一步进步防锈才能,二是进步基料与涂料的黏附性,改善基板涂装性能。普通有三个步骤:一为磷化,先在金属外表构成大量结晶,再用磷盐溶液使金属外表构成一层磷酸盐膜;二是钝化封锁,磷酸盐膜仍有一些孔,用铬酸盐与孔点产生化学反响,构成维护膜。三为纯水洗濯,用去盐或去离子的水洗去钝化液体。
4. Chemical conversion film: it has two functions: one is to further improve the ability of Antirust; the other is to improve the adhesion between base material and coating and improve the coating performance of substrate. Generally, there are three steps: one is phosphating, in which a large amount of crystals are formed on the surface of the metal, and then the phosphate solution is used to make the metal surface form a layer of phosphate film; the other is to passivate and block, and there are still some holes in the phosphate film, and the chromate reacts with the hole points to form the maintenance film. The third is pure water washing, with desalting or deionized water washing to passivation liquid.

5、有机涂层:有机涂层分为底漆和面漆,底漆请求不高,能够采用顺涂,但如今企业为了消费平安,底漆面漆普通都采用逆涂方式。涂后工艺:涂后工艺有印花、压花、可剥离维护膜、层压等,增加了彩钢板的装饰和维护性能。另外,国外一些涂后工艺还有平整和拉直等在冷轧、镀锌消费线中运用的工艺。
5. Organic coating: organic coating is divided into primer and topcoat, primer request is not high, can be used forward, but now enterprises in order to consumer safety, primer surface paint generally use reverse coating method. After coating process: printing, embossing, strippable maintenance film, lamination, etc. can increase the decoration and maintenance performance of color steel plate. In addition, some foreign processes such as leveling and straightening are used in cold rolling and galvanizing production lines.
