熱鍍鋅電纜橋架加工工藝
熱鍍鋅是一種常用的室外防腐鍍鋅技術。鋅層厚度可達65um。熱鍍鋅電纜橋架可抵抗室外風、雨和陽光,不生銹。其跨度為1.5m6m。如采用室外立柱固定,一般間距為6m。熱鍍鋅電纜橋架的荷載與橋架的跨度、材質和高度有關。下面為大家介紹一下熱鍍鋅電纜橋架的加工工藝:
Hot galvanizing is a commonly used outdoor anti-corrosion galvanizing technology. The thickness of zinc layer can reach 65um. Hot galvanized cable tray can resist outdoor wind, rain and sunlight without rusting. Its span is 1.5m to 6m. If outdoor columns are used for fixing, the general spacing is 6m. The safety load of hot galvanized cable tray is related to the span, material and height of the tray. Next, we will introduce the processing technology of hot galvanized cable tray:
1、使用壽命長,生產(chǎn)工業(yè)化程度高,質量穩(wěn)定。因此廣泛應用于受大氣腐蝕嚴重、維護困難的室外環(huán)境。
1. Long service life, high degree of industrialization and stable quality. Therefore, it is widely used in outdoor environment with severe atmospheric corrosion and difficult maintenance.
2、過程不同。熱鍍鋅電纜橋架采用冷軋鋼制作,除銹后浸入600的高溫鋅液中,使橋架表面附著鋅層。5mm薄板厚度不小于65m,5mm及以上厚度不小于86m m,相當于給整個橋架貼上了一層保護膜,所以其熱浸鍍鋅具有優(yōu)異的耐腐蝕性能。對于化工廠、沿海等腐蝕性場所,維護量減少,成本降低。
2. The process is different. The hot-dip galvanized cable tray is made of cold rolled steel. After rust removal, it is immersed in 600 high temperature zinc solution to make the tray surface adhere to zinc layer. The thickness of 5mm thin plate shall not be less than 65m, and the thickness of 5mm and above shall not be less than 86m, which is equivalent to pasting a protective film on the whole bridge, so its hot-dip galvanizing has excellent corrosion resistance. For corrosive sites such as chemical plants and coastal areas, the maintenance amount and cost are reduced.
3、熱鍍鋅板電纜橋架采用熱鍍鋅板(鋅層只有25m),后期沒有防腐處理。梯型電纜橋架與熱鍍鋅電纜橋架相比,外形美觀,但未進行防腐處理。所以不能在室外、化工廠、海邊等有腐蝕性的地方使用。并不是所有的熱鍍鋅都是熱鍍鋅板和電纜橋架,這取決于他的加工工藝。
3. Hot galvanized sheet cable tray is made of hot galvanized sheet (the zinc layer is only 25m), and there is no anti-corrosion treatment in the later stage. Compared with hot-dip galvanized cable tray, ladder type cable tray has beautiful appearance, but no anti-corrosion treatment is carried out. Therefore, it cannot be used outdoors, in chemical plants, at seaside and other corrosive places. Not all hot-dip galvanizing is hot-dip galvanized sheet and cable tray, which depends on his processing technology.
4、熱鍍鋅電纜橋架有鋅層保護,但不生銹是因為鋅在干燥空氣中不易發(fā)生變化,但在潮濕空氣中,可在表面形成一層致密的堿式碳酸鋅膜,可保護內(nèi)部不受腐蝕。而且,當由于某種原因,開槽的電纜橋架損壞了涂層,露出了一個小鋼底座時,鋅和鋼底座形成了一個微型電池,使鋼底座成為陰極,受到保護。所以對于鋅層厚度為65um的電纜橋架,使用30年不生銹,不易損壞。大大延長了橋架使用壽命。
4. Hot dip galvanized cable tray is protected by zinc layer, but it does not rust because zinc is not easy to change in dry air, but a dense alkaline zinc carbonate film can be formed on the surface in humid air, which can protect the interior from corrosion. Moreover, when the grooved cable tray damaged the coating and exposed a small steel base for some reason, the zinc and steel base formed a miniature battery, making the steel base a cathode and protected. Therefore, the cable tray with a zinc layer thickness of 65um will not rust or be damaged after 30 years of use. The service life of the cable tray is greatly extended.
