建筑用彩鋼板一般是以熱鍍鋅鋼板和熱鍍鋁鋅鋼板為基板，主要加工成瓦楞板，或聚氨酯復合夾芯板后，用于建造鋼結(jié)構(gòu)廠房、機場、庫房、冷凍

庫等工業(yè)和商業(yè)建筑的屋頂、墻面、門等。在進行彩鋼板線設計時,首先要考慮的三個基本要素為:質(zhì)量、產(chǎn)品的多樣化、高產(chǎn)，隨著彩涂卷需求量的

增加,對這三個要素的要求更加嚴格。影響涂層機組生產(chǎn)的因素很多,如帶鋼預處理、涂機和固化爐等,但最關鍵的兩個因素是涂機和固化爐。預處理

工藝的主要目的是除去帶鋼表面的油脂和雜質(zhì),并通過鈍化,在鋼板表面形成一層化學轉(zhuǎn)化膜,以提高涂層與帶鋼基板間的附著力和帶鋼耐腐蝕能力。

預處理工藝為:脫脂※刷洗※熱水沖洗※表面調(diào)整※熱水沖洗※鈍化※烘干。

The color steel plate for construction is generally hot galvanized steel plate and hot-plated aluminum zinc steel plate as the substrate, mainly processed into

corrugated board, or polyurethane composite sandwich board, used for the construction of steel structure workshop, airport, warehouse, freezer and other

industrial and commercial buildings roof, wall, door and so on. In the design of color steel plate wire, the first three basic elements should be considered are:

quality, product diversification, high yield, with the increase of the demand for color painting, the requirements for these three elements are more strict.

There are many factors affecting the production of coating units, such as strip pretreatment, coating machine and curing furnace, but the two most critical

factors are coating machine and curing furnace. The main purpose of the pretreatment process is to remove the grease and impurities on the surface of the

strip steel, and to form a chemical conversion film on the surface of the steel plate through passivation to improve the adhesion between the coating and the

strip substrate and the corrosion resistance of the strip steel. The pretreatment process is: degreasing scrub hot water washing surface adjust hot water

flushing passivation drying.
