鍍鋅方管的分類及鍍鋅工藝的幾種方法

發布時間:2019-05-14人氣:570

在我國鍍鋅方管分為熱浸鍍鋅和電鍍鋅。熱浸鍍鋅層厚,涂層均勻,附著力強,使用壽命長。電鍍成本低,表面不光滑,耐腐蝕性比熱浸鍍鋅管差。鍍鋅方管:熱鍍鋅方管方管基板與熔融電鍍液復合物理、發生化學反應,形成致密的鋅鐵合金層耐腐蝕結構。合金層與純鋅層、方管襯底集成在一起。因此,其耐腐蝕性強。

In China, galvanized square tubes are divided into hot dip galvanizing and galvanizing. Hot dip galvanizing has thick coating, uniform coating, strong adhesion and long service life. The electroplating cost is low, the surface is not smooth and the corrosion resistance is worse than that of hot dip galvanized pipe. Galvanized square tube: The hot-dip galvanized square tube square tube base plate and the melt electroplating solution complex physical, chemical reaction, forming a compact zinc-iron alloy layer corrosion-resistant structure. The alloy layer is integrated with pure zinc layer and square tube substrate. Therefore, it has strong corrosion resistance.

鍍鋅方管:冷鍍鋅方管鋅層是電鍍層,鋅層與方管基板分開分層。鋅層很薄,鋅層簡單地附著在方管基板上,很容易脫落。因此,其耐腐蝕性差。在新家中,禁止使用冷鍍鋅方管作為供水管。

Galvanized square pipe: The galvanized layer of cold galvanized square pipe is electroplated, and the zinc layer is separated from the square pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the square tube substrate, which is easy to fall off. Therefore, its corrosion resistance is poor. It is forbidden to use galvanized square pipes as water supply pipes in new homes. 

方管鍍鋅的幾種方法

Several methods of galvanizing square tubes

方管電鍍鋅:由于電解過程,在鹽溶性的鋅電極中,可以進行電子化。合伙和鋅正在下沉到管子的表面。這樣做得很好。然而,這種管道的粘性不足以阻擋持久的凝聚,多孔表面限制了管控壽命五年。

Square tube galvanizing: Due to the electrolysis process, it can be electronized in salt-soluble zinc electrodes. Partnership and zinc are sinking to the surface of the pipe. It's done very well. However, the viscous properties of such pipes are insufficient to prevent persistent condensation, and the porous surface limits the control life for five years.

方管熱鍍鋅:這是一種昂貴的方法,但它的幫助是最耐用的,盡管還不夠,所以需要額外的機械加工。熱鍍鋅是用鍍鋅鋅上鍍鋅的過程。不是所有的鋼碼都可以被這樣處理:如果碳含量超過了0.24%,這種鍍鋅法是不合適的。

Hot-dip galvanizing of square tubes: This is an expensive method, but its help is the most durable, although not enough, so additional mechanical processing is required. Hot-dip galvanizing is a process of galvanizing on galvanized zinc. Not all steel codes can be treated in this way: if the carbon content exceeds 0.24%, this galvanizing process is not appropriate.

方管熱擴散涂層:在水管表面的密封容器中,有一對鋅的蒸汽。在這種情況下,在熱離心機過程中形成的保護層是非常強大和平穩的,無論管道配置的復雜性,它幾乎是不存在的。在焊接時有一種稀有的東西。鍍鋅管的服役期為15年,這是值得的,因為表面上沒有鋅光澤。

Square pipe thermal diffusion coating: There is a pair of zinc vapors in the sealed container on the surface of the water pipe. In this case, the protective layer formed in the thermal centrifuge process is very strong and stable, regardless of the complexity of pipeline configuration, it almost does not exist. There is something rare in welding. The service life of galvanized pipes is 15 years, which is worthwhile because there is no zinc gloss on the surface.

方管冷鍍鋅:這種方法適用于已經運行的溝通,并代表人工染料,含有鋅、手工或氣體。這是一個擁抱。這種涂層有時并不是熱鍍鍍,但不需要拆卸,盡管機械的可持續性是不可思議的。以下是:在第一種情況下,不超過5到6年,在第二種情況下,使用時間增加到7到8年。

Square tube cold galvanizing: This method is suitable for communication already in operation, and represents artificial dyes, containing zinc, manual or gas. It's a hug. Sometimes this coating is not hot-dipped, but it does not need to be disassembled, although the mechanical sustainability is incredible. The following are: in the first case, no more than 5 to 6 years, in the second case, the use time increased to 7 to 8 years.
