鍍鋅板是建筑裝修中一種比較常見的建材，現(xiàn)在使用的比較多的鍍鋅板材質(zhì)主要有非合金熱鍍鋅鋼帶和合金化熱鍍鋅鋼帶、合金化鍍鋅鋼板、熱金鍍鋅鋼板、電鍍鋅鋼板、單面鍍鋅鋼板等。一般鍍鋅板的厚度是在0.4~3.2mm之間。

Galvanized sheet is a common building materials in building decoration, now the use of more galvanized sheet material is mainly non-alloy hot galvanized steel strip and alloyed hot galvanized steel strip, alloyed galvanized steel sheet, hot gold galvanized steel sheet, electroplated galvanized steel sheet, single galvanized steel sheet. The thickness of galvanized plate is between 0.4~3.2mm.

熱鍍鋅鋼板的鍍層較厚(一般為60-600g/m2)，基板性能受到熱鍍鋅工藝的影響，主要用于建筑、日用器具及汽車等，可直接露天使用；電鍍鋅鋼板的鍍層較?。ㄒ话銥?/font>10-160g/m2）,基板性能不受電鍍鋅工藝的影響，主要用于汽車、家電、電氣、及涂層原板等，一般需凃漆，不宜直接露天使用。

The coating of hot dip galvanized steel sheet is thick (generally 60-600g / m2), the substrate performance is affected by hot dip galvanizing process, mainly used for construction, daily appliances and automobiles, and can be used directly in the open; galvanized steel sheet is thin (generally 10-160g / m2), the substrate performance is not affected by the galvanized process, mainly used in automobile, home appliances, electrical, and coated original plate, generally coated paint, not direct open use.

鍍鋅板耐蝕特性顯著：鋅的標準電極電位較低，鐵基上的鍍鋅層在一般的腐蝕介質(zhì)中為陽極鍍層，該鍍層可以有效減緩鋼基板遭受腐蝕的程度，其在耐腐性能方面較冷軋板有著明顯優(yōu)勢。平整致密的鍍鋅層可以通過鋅的耐蝕性能進行腐蝕保護，切口、鍍層局部破損區(qū)域可以通過犧牲陽極（鋅層）保護，降低腐蝕速率。此外，鋅鍍層的無毒、廉價且防護性能優(yōu)良，令鍍鋅工藝在防腐技術(shù)中占有重要的地位。

The corrosion resistance characteristics of galvanized plate are significant: the standard electrode potential of zinc is low, and the galvanized layer on the iron base is the anode coating in the general corrosion medium. The coating can effectively reduce the corrosion degree of steel substrate, and it has obvious advantages over cold rolled plate in corrosion resistance. The flat and dense galvanizing layer can be protected by the corrosion resistance of zinc, and the local damaged area of the incision and coating can be protected by sacrificing the anode (zinc layer) to reduce the corrosion rate. In addition, the zinc coating is non-toxic, cheap and excellent protective performance, so that the galvanizing process plays an important role in the anticorrosion technology.
