彩涂板都是由基板、鍍層、涂層組成。影響防腐性能的主要是涂層和鍍層。按照鍍層材質(zhì)的不同分為鍍鋅彩涂板和鍍鋁鋅彩涂板。

金屬鋁在防腐上有其獨到之處該金屬在空氣中會迅速形成致密而厚實的氧化鋁膜，這種氧化鋁膜的迅速形成阻止了腐蝕的進(jìn)一步侵入。

鍍鋁鋅板利用了鋁的氧化膜遮蓋保護(hù)作用與鋅對鐵的電化學(xué)保護(hù)作用，一般認(rèn)為較鍍鋅板有更好的防腐性能，

但是鍍鋁鋅對于氨水的耐腐蝕性能較鍍鋅材料差很多，所以在畜禽舍環(huán)境不建議采用鍍鋁鋅。

Color coating board is made up of base plate, coating and coating. Coating and coating are mainly affected by the corrosion resistance performance.

According to the different coating material is divided into galvanized color coating plate and aluminum plated galvanized color coating plate.

The metal quickly forms a dense and thick alumina film in the air, the rapid formation of which prevents further invasion of corrosion.

Aluminized zinc plate uses the protective effect of aluminum oxide film and zinc electrochemical protection of iron,

which is generally believed to have better anticorrosion performance than galvanized plate,

but the corrosion resistance of aluminum zinc for ammonia is much worse than that of galvanized material,

so it is not recommended to use aluminum zinc in the livestock and poultry house environment.
