5、rasion防腐蝕性極佳；excellent resistance to corrosion不易剝落；resistance to chipping能抵抗外在環(huán)境因素：日照，咸水；resistance to the elements: sunlight, salt water適應(yīng)工作溫度范圍190到260；working temperature rang from:-190to260有多種顏色:available in a wide range of colors熱鍍鋅熱鍍鋅是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)設(shè)施上。是將除銹后的鋼件浸入500左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層

6、，從而起到防腐的目的。一般用于大量輸電塔、通訊塔, 機(jī)械交通, 熱工, 建筑, 電力,等。Hot-dip galvanizing is an effective method of metal anti-corrosion is mainly used in various sectors of the metal structure facilities. Is to rust the steel parts after 500 or so immersed in the melting of zinc solution, so that the surface adhesion of zi

7、nc layer of steel members, which play an anti-corrosion purposes. Thats generally used to the large number of transmission towers, communication towers, machinery and transport, thermal engineering, construction, electricity, and so on.熱鍍鋅工藝流程：成品去油-水洗-酸洗-清洗-助溶劑-烘干-鍍鋅-冷卻-完工Hot-dip galvanizing process
