大家對彩鋼板并不陌生，我們經常在工地上看到它的身影。彩色鋼板雖然有很多優(yōu)點，但不可避免地存在問題。事實上，造成彩鋼板損壞的原因有三：斷裂、磨損和腐蝕。其中，腐蝕是三種較為復雜的形式之一，對彩鋼板的破壞性也很大。由于彩鋼板在腐蝕發(fā)生時處于金屬與環(huán)境(介質)的界面上，并發(fā)生化學或電化學反應，所以彩鋼板的腐蝕分類有以下這幾種：
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、彩鋼板按腐蝕程度分為：
1. Color steel plates are divided into:
根據腐蝕機理：化學腐蝕、電化學腐蝕和物理腐蝕。
According to the corrosion mechanism: chemical corrosion, electrochemical corrosion and physical corrosion.
根據腐蝕環(huán)境：干腐蝕和濕腐蝕。
According to the corrosive environment: dry corrosion and wet corrosion.
根據金屬材料：金屬手冊中常見和實用的金屬。
According to metal materials: common and practical metals in the metal manual.
按腐蝕形式分為點蝕和應力腐蝕斷裂。
According to the corrosion form, it can be divided into pitting corrosion and stress corrosion fracture.
根據適用范圍：實際上，它是按腐蝕環(huán)境分類的一種特殊應用。
According to the scope of application: in fact, it is a special application classified by corrosive environment.
彩鋼板的防腐現象主要是指上述(1)和(2)點。(1)點干腐蝕屬于化學機理，濕腐蝕屬于電化學機理。點(3)到(5)是點(1)和(2)的進一步分類。彩涂鋼板的防腐機理是通過涂層將基體與腐蝕介質分離，防止基體表面發(fā)生化學或電化學反應。因此，我們要研究的防腐問題應概括為鍍層鋼板表面的化學腐蝕和電化學腐蝕。
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、彩鋼板防腐措施：
2. Anti corrosion measures for color steel plate:
在選擇金屬材料時，盡量選擇耐大氣腐蝕的材料。
When selecting metal materials, try to choose materials resistant to atmospheric corrosion.
使用表面保護涂層。
Use surface protective coating.
包裝前應進行防銹處理，貯存時應保持干燥、清潔。
Rust prevention treatment shall be carried out before packaging, and it shall be kept dry and clean during storage.
改變成分，加入緩蝕劑，減緩腐蝕過程。
Change the composition and add corrosion inhibitor to slow down the corrosion process.
在結構設，盡量避免裂縫和溝槽易積水而引起腐蝕應力斷裂的地方。
In the structural design, try to avoid the places where cracks and grooves are easy to accumulate water and cause corrosion stress fracture.
