濟(jì)南彩鋼板房在一年四季的使用期間，在大氣，溫度，水等條件的作用下會(huì)發(fā)生一定的化學(xué)反應(yīng)，遭到破壞，從而影響彩鋼房的美觀和質(zhì)量，那么腐蝕的原因有哪些呢？該如何防腐蝕呢？

During the use of Jinan color steel plate house all year round, certain chemical reactions will occur under the action of atmosphere, temperature, water and other conditions, and will be damaged, thus affecting the beauty and quality of the color steel house. What are the reasons for corrosion? How to prevent corrosion?

活動(dòng)板房的鋼構(gòu)件一直處在陽光、風(fēng)雨、溫度和濕度變化的環(huán)境中，大氣里面所含的氧氣和水分對(duì)活動(dòng)板房的鋼構(gòu)造的骨架會(huì)進(jìn)行電化學(xué)的侵蝕，尤其是大氣里面的二氧化硫，氯離子和酸雨，對(duì)鋼構(gòu)造的侵蝕更加厲害。

The steel members of the movable plank house are always in the environment of sunshine, rain, temperature and humidity changes. The oxygen and moisture contained in the atmosphere will electrochemically corrode the skeleton of the steel structure of the movable plank house, especially the sulfur dioxide, chloride ions and acid rain in the atmosphere, which will corrode the steel structure more severely.

因此，活動(dòng)板房構(gòu)件的強(qiáng)度需要乘以一個(gè)強(qiáng)度折減的數(shù)值，這個(gè)數(shù)值和彩鋼板的彩鋼板房的構(gòu)造所位于的大氣環(huán)境和它使用年限有關(guān)系。彩鋼板房侵蝕一直是難以解決的一道難題。

Therefore, the strength of the components of the movable plank house needs to be multiplied by a strength reduction value, which is related to the atmospheric environment where the structure of the color steel plank house is located and its service life. The erosion of color steel plank houses has always been a difficult problem to solve.

還有，彩鋼板房的工場預(yù)定的進(jìn)程其中，要提高鋼材的防腐方法，按照鋼材的侵蝕的電化學(xué)原理，只需要破壞侵蝕電池的產(chǎn)生或猛烈的阻撓陰陽進(jìn)程的進(jìn)行，就可以防止輕鋼構(gòu)造的侵蝕。

In addition, according to the predetermined process of the workshop of the color steel plate house, to improve the anti-corrosion method of the steel, according to the electrochemical principle of the corrosion of the steel, the corrosion of the light steel structure can be prevented only by destroying the generation of the corrosion battery or violently blocking the progress of the yin-yang process.

現(xiàn)在使用保護(hù)層的方法安放鋼構(gòu)件侵蝕現(xiàn)今通用的方法，通過在彩鋼板房的骨架和彩鋼板的鐵皮上面噴涂防止生銹的油漆，金屬的表層產(chǎn)生保護(hù)膜，令金屬與氣氛里面的侵蝕化學(xué)成分進(jìn)行隔離。

Now, the method of protective layer is used to place the steel members to corrode. It is a common method nowadays. By spraying anti rust paint on the framework of the color steel plate house and the iron sheet of the color steel plate, a protective film is produced on the surface of the metal to isolate the metal from the corrosive chemical components in the atmosphere.

彩鋼板房的防腐措施：

Anti corrosion measures for color steel plate house:

1、熱浸鋅：

1. Hot dip galvanizing:

2、熱噴鋁（鋅）復(fù)合涂層

2. Thermal spraying aluminum (zinc) composite coating

涂層法：涂層法防腐蝕性一般不如長效防腐蝕方法。所以用于室內(nèi)鋼結(jié)構(gòu)或相對(duì)易于維護(hù)的室外鋼結(jié)構(gòu)較多。它一次成本低，但用于戶外時(shí)維護(hù)成本較高。涂層法的施工的重要一步是除銹。的涂層依賴于徹底的除銹。

Coating method: the corrosion resistance of coating method is generally inferior to that of long-term corrosion protection method. There are many outdoor steel structures that are used for indoor steel structures or relatively easy to maintain. It has low primary cost but high maintenance cost when used outdoors. Rust removal is an important step in the construction of coating method. High quality coating depends on thorough rust removal.

所以要求高的涂層一般多用噴砂噴丸除銹，露出金屬的光澤，除去所有的銹跡和油污?，F(xiàn)場施工的涂層可用手工除銹。涂層的選擇要考慮周圍的環(huán)境。不同的涂層對(duì)不同的腐蝕條件有不同的耐受性。

Therefore, the coatings with high requirements are generally derusted by sand blasting and shot blasting to expose the metal luster and remove all rust and oil stains. The coating applied on site can be derusted manually. The surrounding environment shall be taken into consideration when selecting the coating. Different coatings have different resistance to different corrosion conditions.

涂層一般有底漆（層）和面漆（層）之分。底漆含粉料多，基料少。成膜粗糙，與鋼材粘附力強(qiáng)，與面漆結(jié)合性好。面漆則基料多，成膜有光澤，能保護(hù)底漆不受大氣腐蝕，并能抗風(fēng)化。不同的涂料之間有相容與否的問題，前后選用不同涂料時(shí)要注意它們的相容性。

The coating is generally divided into primer (layer) and finish (layer). The primer contains more powder and less base material. Rough film formation, strong adhesion with steel and good adhesion with finish. The topcoat has a lot of base materials and a shiny film, which can protect the primer from atmospheric corrosion and resist weathering. There is a problem of compatibility between different coatings. When selecting different coatings before and after, attention should be paid to their compatibility.
