大家对彩钢板并不陌生，我们经常在工地上看到它的身影。彩色钢板虽然有很多优点，但不可避免地存在问题。事实上，造成彩钢板损坏的原因有三：断裂、磨损和腐蚀。其中，腐蚀是三种较为复杂的形式之一，对彩钢板的破坏性也很大。由于彩钢板在腐蚀发生时处于金属与环境(介质)的界面上，并发生化学或电化学反应，所以彩钢板的腐蚀分类有以下这几种：
We are not unfamiliar with color steel plate. We often see its figure on the construction site. Although color steel plate has many advantages, it inevitably has problems. In fact, there are three reasons for the damage of color steel plate: fracture, wear and corrosion. Among them, corrosion is one of the three more complex forms, which is also very destructive to color steel plate. Since the color steel plate is at the interface between metal and environment (medium) when corrosion occurs, and chemical or electrochemical reaction occurs, the corrosion classification of color steel plate is as follows:
1、彩钢板按腐蚀程度分为：
1. Color steel plates are divided into:
根据腐蚀机理：化学腐蚀、电化学腐蚀和物理腐蚀。
According to the corrosion mechanism: chemical corrosion, electrochemical corrosion and physical corrosion.
根据腐蚀环境：干腐蚀和湿腐蚀。
According to the corrosive environment: dry corrosion and wet corrosion.
根据金属材料：金属手册中常见和实用的金属。
According to metal materials: common and practical metals in the metal manual.
按腐蚀形式分为点蚀和应力腐蚀断裂。
According to the corrosion form, it can be divided into pitting corrosion and stress corrosion fracture.
根据适用范围：实际上，它是按腐蚀环境分类的一种特殊应用。
According to the scope of application: in fact, it is a special application classified by corrosive environment.
彩钢板的防腐现象主要是指上述(1)和(2)点。(1)点干腐蚀属于化学机理，湿腐蚀属于电化学机理。点(3)到(5)是点(1)和(2)的进一步分类。彩涂钢板的防腐机理是通过涂层将基体与腐蚀介质分离，防止基体表面发生化学或电化学反应。因此，我们要研究的防腐问题应概括为镀层钢板表面的化学腐蚀和电化学腐蚀。
The anti-corrosion phenomenon of color steel plate mainly refers to points (1) and (2) above. (1) Point dry corrosion belongs to chemical mechanism and wet corrosion belongs to electrochemical mechanism. Points (3) to (5) are further classifications of points (1) and (2). The anti-corrosion mechanism of color coated steel plate is to separate the substrate from the corrosive medium through the coating to prevent chemical or electrochemical reaction on the substrate surface. Therefore, the anti-corrosion problem we want to study should be summarized as chemical corrosion and electrochemical corrosion on the surface of coated steel plate.
2、彩钢板防腐措施：
2. Anti corrosion measures for color steel plate:
在选择金属材料时，尽量选择耐大气腐蚀的材料。
When selecting metal materials, try to choose materials resistant to atmospheric corrosion.
使用表面保护涂层。
Use surface protective coating.
包装前应进行防锈处理，贮存时应保持干燥、清洁。
Rust prevention treatment shall be carried out before packaging, and it shall be kept dry and clean during storage.
改变成分，加入缓蚀剂，减缓腐蚀过程。
Change the composition and add corrosion inhibitor to slow down the corrosion process.
在结构设，尽量避免裂缝和沟槽易积水而引起腐蚀应力断裂的地方。
In the structural design, try to avoid the places where cracks and grooves are easy to accumulate water and cause corrosion stress fracture.
