1.熱浸鍍鋅。
1. Hot dip galvanizing.
因熱浸鍍鋅具有較好的耐腐蝕性和相對較高的性能與對比,因此鋼質(zhì)熱浸鍍鋅電纜橋架國內(nèi)外獲得廣泛運用。針對厚壁及長細比較大的預制構(gòu)件,在熱浸鍍鋅時很容易產(chǎn)生形變等諸多問題,須在
濟南橋架的在結(jié)構(gòu)上及鍍鋅工藝上進行考量。
Because hot-dip galvanizing has good corrosion resistance and relatively high performance and price comparison, steel hot-dip galvanized cable trays are widely used at home and abroad. For the prefabricated components with thick wall and large slenderness ratio, it is easy to produce deformation and many other problems during hot-dip galvanizing, which should be considered in the structure and galvanizing process of Jinan bridge.
2.電鍍鋅。
2. Electrogalvanizing.
電鍍鋅在我國有標準查詢。對電鍍層類型的挑選、鍍層厚度、涂層附著強度、抗腐蝕實驗等等都有明確規(guī)定,這種標準化的采用目標不一樣,具體內(nèi)容規(guī)定也存在差異。目前我國生產(chǎn)制造電鍍鋅電纜橋架生產(chǎn)廠家比較多,在參考運用以上相關(guān)標準規(guī)范時也有所不同。為了保證電鍍鋅的耐腐蝕性,能夠采用電鍍鋅鎳基合金或熱鍍鋅之后進行高不銹鋼鈍化。
Electrogalvanizing is inquired in our national standard. There are clear regulations on the selection of electroplating coating type, coating thickness, coating adhesion strength, corrosion resistance test, etc. The adoption objectives of this standardization are different, and the specific contents are also different. At present, there are many manufacturers of galvanized cable tray in China, and they are also different when referring to the above relevant standards and specifications. In order to ensure the corrosion resistance of electrogalvanizing, high stainless steel passivation can be carried out after electrogalvanizing nickel-base alloy or hot galvanizing.

3.靜電粉末噴涂。
3. Electrostatic powder spraying.
噴涂材料一般為聚乙烯粉末狀,聚酯粉末狀或防腐蝕粉末狀。涂層厚度在100上下。靜電粉末噴涂具備表面美觀大方、防化學浸蝕性能好的特征。但是和金屬鍍層相比附著強度低,耐侵蝕和顆粒物損壞能力較差。使用中有質(zhì)變難題,易導致部分涂層脫落,從而使得鋼材基材生銹,造成鍍層大規(guī)模鼓包脫落。
Spraying materials are generally polyethylene powder, polyester powder or anti-corrosion powder. The coating thickness is above 100. Electrostatic powder spraying has the characteristics of beautiful surface and good chemical etching resistance. However, compared with the metal coating, the adhesion strength is low, and the resistance to corrosion and particle damage is poor. There is a problem of quality change in use, which is easy to cause part of the coating to fall off, thus making the steel substrate rusty and causing the coating to fall off in large scale.
4.涂防腐漆。
4. Apply anti-corrosion paint.
針對截面尺寸比較大的預制構(gòu)件,由于受到鋅鍋、鍍槽、烘干箱等限定,一般只有采用涂防腐漆的方法去解決。它盡管具備低成本、方便使用等優(yōu)點;但耐腐蝕功能較弱。應用周期短,維護保養(yǎng)工作強度大,一般不適合采用。
For prefabricated components with relatively large section size, due to the limitation of zinc pot, plating bath, drying oven, etc., generally only the method of coating anti-corrosion paint is used to solve the problem. Although it has the advantages of low cost and convenient use; However, the corrosion resistance function is weak. It is generally not suitable for use because of its short application cycle and high maintenance intensity.
5.采用鋁合金制作電纜橋架,海外早就運用。不論是沿海地區(qū)含鹽份地域或高環(huán)境濕度又帶有二氧化硫氣體地域。鋁合金型材制作而成的電纜橋架,采用當然曝露,檢測結(jié)果顯示比鋼質(zhì)電纜橋架具備明顯的優(yōu)異的耐腐蝕性。有什么需求或者疑惑就來我們網(wǎng)站

5. The aluminum alloy cable tray has been used overseas for a long time. No matter in coastal areas with salt content or areas with high environmental humidity and sulfur dioxide gas. The cable tray made of aluminum alloy profiles is exposed naturally, and the test results show that it has significantly better corrosion resistance than the steel cable tray.
