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.

彩鋼板

Color steel plate

1、彩鋼板的基材能夠選用冷軋板或熱鍍電鍍層鋼材，固然彩鋼板的有機涂層局部有很好的防腐蝕作用，但有機涂層中仍有一些小的空隙，能夠讓空氣及水份都可能進入進，使其基材生銹，不能用，所以采用無鍍層的基材做成的彩鋼板，運用壽命短，且劃傷后很容易擴散，招致涂層剝落。彩鋼板的基材以鍍鋅鋼板或鍍鋅合金鋼板為主。

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、彩涂的消費程序分為基材的前處置，化學轉(zhuǎn)化膜(非有機金屬涂層)，有機非金屬涂層，另外有些消費線還有涂后工藝。

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、基材前處置：作為基材的鍍鋅鋼板假如不是在消費后直接進入一道彩涂工序，則可能會在運輸過程中呈現(xiàn)銹蝕(白銹)，灰塵，及其他污染。假如不能把這些去掉，則會影響彩涂的質(zhì)量和效果。廢品的質(zhì)以及一切物理、化學性能都與前處置有親密關(guān)切。另外，在鍍鋅消費后，為了防銹而涂油，這些油也是要在彩涂消費行進行準備的，如今運用較多的前處置辦法為堿溶液脫脂法。

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、化學轉(zhuǎn)化膜：作用有二，一是進一步進步防銹才能，二是進步基料與涂料的黏附性，改善基板涂裝性能。普通有三個步驟：一為磷化，先在金屬外表構(gòu)成大量結(jié)晶，再用磷鹽溶液使金屬外表構(gòu)成一層磷酸鹽膜;二是鈍化封鎖，磷酸鹽膜仍有一些孔，用鉻酸鹽與孔點產(chǎn)生化學反響，構(gòu)成維護膜。三為純水洗濯，用去鹽或去離子的水洗去鈍化液體。

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、有機涂層：有機涂層分為底漆和面漆，底漆請求不高，能夠采用順涂，但如今企業(yè)為了消費平安，底漆面漆普通都采用逆涂方式。涂后工藝：涂后工藝有印花、壓花、可剝離維護膜、層壓等，增加了彩鋼板的裝飾和維護性能。另外，國外一些涂后工藝還有平整和拉直等在冷軋、鍍鋅消費線中運用的工藝。

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.
