養(yǎng)殖場怎樣選擇彩鋼板？
How does the farm choose the color steel plate?
養(yǎng)殖場為了更快速的投入生產(chǎn)，很多農(nóng)戶選用彩鋼瓦直接鋪設(shè)在房梁上，簡單快捷，省心省力。彩鋼瓦就是彩涂板，就是在薄薄的鋼板表面鍍鋅或鍍鋁鋅，在鋼板生成一層防腐蝕鍍層，然后再在鋼板鍍層上涂上PE等防腐蝕涂料。
In order to quickly put into production quickly, many farmers choose color steel tile directly laid on the beam, simple and fast, save worry and effort.Color steel tile is the color coating plate, is galvanized in the thin steel sheet surface or aluminum galvanized on the steel sheet, to produce a layer of anti-corrosion coating, and then on the steel sheet coating with PE and other anti-corrosion coating.
豬舍內(nèi)部主要產(chǎn)生氨氣較多，氨氣遇空氣中水分呈堿性，按照優(yōu)耐舍建筑的使用經(jīng)驗，豬舍內(nèi)部墻壁與吊頂選用鍍鋅彩涂板，屋面瓦選用鍍鋁鋅彩涂板較佳。
More ammonia is mainly produced inside the piggery, and ammonia is alkaline in the air. According to the use experience of the excellent resistant building, the internal wall and ceiling of the piggery are selected with galvanized color coating board, and the roof tile is better with aluminum galvanized color coating board.
很多人選購彩鋼板時，很容易忽視鍍層的厚度。常規(guī)來看，鍍層厚度越大，耐腐蝕性能越好。
When many people buy color steel plate, it is easy to ignore the thickness of the plating.Generally speaking, the greater the coating thickness, the better the corrosion resistance.
鍍層厚度主要是影響到彩涂鋼板的切口腐蝕性能，切口腐蝕是電化學(xué)腐蝕，影響因素有預(yù)處理層、底漆、基板厚度、鍍層厚度等。在正常情況下，預(yù)處理層和底漆相對比較固定，影響切口腐蝕性能的就是基板厚度及鍍層厚度了?；逶奖?、鍍層越厚，耐切口腐蝕的性能越好。關(guān)于這點，國際上有很多研究，目前比較公認的就是鋅比。即鍍層單面每平方米鍍層重量的克數(shù)/基板的厚度（以毫米計）。認為鋅比大于100是有效防止彩涂鋼板切口腐蝕的保證。舉例說明，如果0.6mm的鋼板，其單面鍍鋅量就要達到60克/平方米。盡管鍍鋁鋅光板的耐腐蝕性能優(yōu)于熱鍍鋅，但對切口腐蝕蔓延來說，鋅比也適用于熱鍍鋁鋅。
The coating thickness mainly affects the incision corrosion performance of the color-coated steel plate. The incision corrosion is electrochemical corrosion, and the influencing factors are pretreatment layer, primer, substrate thickness, coating thickness, etc.Under normal circumstances, the pretreatment layer and the primer are relatively fixed, and the thickness of the substrate and the coating thickness will affect the corrosive performance of the incision.The thinner the substrate and the thicker the coating, the better the incision corrosion resistance performance.On this point, there are many international studies, which is more recognized as the zinc ratio.That is, the thickness of grams per square meter of plating weight (in mm).It is considered that the zinc ratio is greater than 100 is an effective protection against corrosion of color coated steel plate.For example, if a 0.6mm steel plate, its single surface galvanization amount will reach 60 g / m 2.Although the corrosion resistance of the aluminum-plated galvanized light plate is better than the hot-plated galvanizing, the zinc ratio is also suitable for the incision corrosion spread.
