大家對(duì)彩鋼板并不陌生，我們經(jīng)常在工地上看到它的身影。彩色鋼板雖然有很多優(yōu)點(diǎn)，但不可避免地存在問(wèn)題。事實(shí)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(fù)雜的形式之一，對(duì)彩鋼板的破壞性也很大。由于彩鋼板在腐蝕發(fā)生時(shí)處于金屬與環(huán)境(介質(zhì))的界面上，并發(fā)生化學(xué)或電化學(xué)反應(yīng)，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(jù)腐蝕機(jī)理：化學(xué)腐蝕、電化學(xué)腐蝕和物理腐蝕。
According to the corrosion mechanism: chemical corrosion, electrochemical corrosion and physical corrosion.
根據(jù)腐蝕環(huán)境：干腐蝕和濕腐蝕。
According to the corrosive environment: dry corrosion and wet corrosion.
根據(jù)金屬材料：金屬手冊(cè)中常見和實(shí)用的金屬。
According to metal materials: common and practical metals in the metal manual.
按腐蝕形式分為點(diǎn)蝕和應(yīng)力腐蝕斷裂。
According to the corrosion form, it can be divided into pitting corrosion and stress corrosion fracture.
根據(jù)適用范圍：實(shí)際上，它是按腐蝕環(huán)境分類的一種特殊應(yīng)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(xiàn)象主要是指上述(1)和(2)點(diǎn)。(1)點(diǎn)干腐蝕屬于化學(xué)機(jī)理，濕腐蝕屬于電化學(xué)機(jī)理。點(diǎn)(3)到(5)是點(diǎn)(1)和(2)的進(jìn)一步分類。彩涂鋼板的防腐機(jī)理是通過(guò)涂層將基體與腐蝕介質(zhì)分離，防止基體表面發(fā)生化學(xué)或電化學(xué)反應(yīng)。因此，我們要研究的防腐問(wèn)題應(yīng)概括為鍍層鋼板表面的化學(xué)腐蝕和電化學(xué)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(shí)，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(hù)涂層。
Use surface protective coating.
包裝前應(yīng)進(jìn)行防銹處理，貯存時(shí)應(yīng)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(guò)程。
Change the composition and add corrosion inhibitor to slow down the corrosion process.
在結(jié)構(gòu)設(shè)，盡量避免裂縫和溝槽易積水而引起腐蝕應(yīng)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.
