建筑物（屋面板和外墻板）本身對材料的要求可分成安全性能（耐沖擊、耐風壓和防火性）、居住性能（防水性、隔熱性和隔音性）、

能（耐污染性、耐侯性和外觀保持性）、生產加工性（經濟性、易加工、易維護和修補）。隨著我國各類建筑場館對綠色發展、環境友好、

性能耐久、戶外美觀多樣要求越來越高，國內彩涂市場競爭相當激烈，目前全國彩涂產能突破千萬噸。彩涂板的質量主要取決于彩涂板生產廠，

但是如果加工及安裝設備和方法不當，也會在不同程度上引起最終產品的外觀和使用壽命的損傷。

建筑用彩涂現在通用的鍍層為熱鍍鋅和熱鍍鋁鋅兩種。對于彩涂來說，兩種基板的應用領域區分不大，在相對酸性的環境下，

鍍鋁鋅基板是比較好的選擇。而對于潮濕的、堿性環境下使用，鍍鋅基板的切口耐蝕性的優勢得以體現。

Building (house panel and exterior panels) itself for material requirements can be divided into safety performance (impact resistance,

wind pressure resistance and fire resistance), residential performance (waterproof, heat insulation and sound insulation), durability (pollution resistance,

hou resistance and appearance retention), production and processing (economy, easy processing, easy maintenance and repair).

With the increasing requirements of various building venues for green development, environmental friendliness, durable performance and beautiful outdoors,

the competition in the domestic color coating market is quite fierce. At present, the national color coating production capacity has exceeded 10 million tons.

The quality of the color coating board mainly depends on the color coating board factory,

but if the processing and installation equipment and methods are not appropriate,

it will also cause the appearance and service life of the final product to varying degrees.

Architectural color coating now common coating for hot galvanizing and hot aluminum zinc two.For color coating,

the application field of the two substrates is not much different, in a relatively acidic environment, aluminum-plated galvanized substrate is a better choice.

For humid and alkaline environment, the advantages of incision corrosion resistance of galvanized substrate can be reflected.
