熱鍍鋅電纜橋架的耐磨性有哪些？
1、電纜橋架鋼鐵表面覆蓋著一層厚而致密的純鋅層，可以防止鋼鐵基體與任何腐蝕性溶液接觸，保護鋼鐵基體不受腐蝕。在一般氣氛下，鋅層表面形成一層薄而致密的氧化鋅層，難溶于水，所以對剛性基體起到一定的保護作用。如果氧化鋅與大氣中的其他成分反應(yīng)生成不溶性鋅鹽，防腐效果更理想。
1. The steel surface of cable tray is covered with a thick and dense pure zinc layer, which can prevent the steel matrix from contacting with any corrosive solution and protect the steel matrix from corrosion. In general atmosphere, a thin and dense zinc oxide layer is formed on the surface of the zinc layer, which is hard to dissolve in water, so it plays a certain role in protecting the rigid matrix. If zinc oxide reacts with other components in the atmosphere to form insoluble zinc salt, the anti-corrosion effect is more ideal.
2、它具有鐵鋅合金層，結(jié)合緊密，在海洋鹽霧環(huán)境和工業(yè)環(huán)境中表現(xiàn)出獨特的耐腐蝕性。
2. It has an iron-zinc alloy layer, which is closely combined, and shows unique corrosion resistance in marine salt fog environment and industrial environment.
3、由于結(jié)合牢固，鋅和鐵互溶，耐磨性強。
3. Due to the firm combination, zinc and iron are mutually soluble and have strong wear resistance.
4、由于鋅具有良好的延展性，其合金層牢固地附著在鋼基體上，熱鍍零件可以進行冷沖壓、軋制、拉伸和彎曲而不損傷鋅層。
4. Due to the good ductility of zinc, its alloy layer is firmly attached to the steel substrate, and the hot-plated parts can be cold pressed, rolled, stretched and bent without damaging the zinc layer.
5、鋼結(jié)構(gòu)熱鍍鋅后，相當(dāng)于一次退火處理，可很好的提高鋼基體的力學(xué)性能，清理鋼件成型和焊接時的應(yīng)力，便于剛性結(jié)構(gòu)的車削。
5. After hot-dip galvanizing of steel structure, it is equivalent to one annealing treatment, which can improve the mechanical properties of steel substrate, clean the stress during forming and welding of steel parts, and facilitate the turning of rigid structure.
6、熱鍍鋅后的表面光亮美觀。
6. The surface after hot galvanizing is bright and beautiful.
7、純鋅鍍層是熱鍍鋅中的塑性鋅鍍層。它的性質(zhì)基本上接近純鋅的性質(zhì)，并且具有延展性，因此具有柔韌性。
7. Pure zinc coating is a plastic zinc coating in hot galvanizing. Its properties are basically close to those of pure zinc, and it has ductility, so it has flexibility.
8、熱浸橋表面是亮銀色，有點像不銹鋼的顏色。一般橋架廣泛用于電力布線，安裝要求橋架表面做防火處理。
8. The surface of the hot-dip bridge is bright silver, a little like the color of stainless steel. General cable tray is widely used for power wiring, and the surface of cable tray is required to be fireproof during installation.
