养殖场怎样选择彩钢板？
How does the farm choose the color steel plate?
养殖场为了更快速的投入生产，很多农户选用彩钢瓦直接铺设在房梁上，简单快捷，省心省力。彩钢瓦就是彩涂板，就是在薄薄的钢板表面镀锌或镀铝锌，在钢板生成一层防腐蚀镀层，然后再在钢板镀层上涂上PE等防腐蚀涂料。
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.
猪舍内部主要产生氨气较多，氨气遇空气中水分呈碱性，按照优耐舍建筑的使用经验，猪舍内部墙壁与吊顶选用镀锌彩涂板，屋面瓦选用镀铝锌彩涂板较佳。
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.
很多人选购彩钢板时，很容易忽视镀层的厚度。常规来看，镀层厚度越大，耐腐蚀性能越好。
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.
镀层厚度主要是影响到彩涂钢板的切口腐蚀性能，切口腐蚀是电化学腐蚀，影响因素有预处理层、底漆、基板厚度、镀层厚度等。在正常情况下，预处理层和底漆相对比较固定，影响切口腐蚀性能的就是基板厚度及镀层厚度了。基板越薄、镀层越厚，耐切口腐蚀的性能越好。关于这点，国际上有很多研究，目前比较公认的就是锌比。即镀层单面每平方米镀层重量的克数/基板的厚度（以毫米计）。认为锌比大于100是有效防止彩涂钢板切口腐蚀的保证。举例说明，如果0.6mm的钢板，其单面镀锌量就要达到60克/平方米。尽管镀铝锌光板的耐腐蚀性能优于热镀锌，但对切口腐蚀蔓延来说，锌比也适用于热镀铝锌。
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.
