How does the farm choose the color steel plate?
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.
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.
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.
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.
