Color steel plate refers to color-coated steel plate. Color-coated steel plate is a steel plate with organic coating. It has good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, and has the advantages of steel plate original strength and low cost. And other characteristics. The base plate of color coated steel plate is cold rolled base plate, hot-dip galvanized base plate and electro-galvanized base plate. The coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and plastisol. Color coated steel plate The surface condition can be divided into coated plate, embossed plate and printing plate. Based on the analysis of the coating structure characteristics and mechanism of the color coated plate, the color steel plate is rolled.
The service life of the color-coated board essentially refers to the uniform embodiment of the corrosion resistance of the color-coated board substrate and the weather resistance of the game painting, the processing of the color steel plate, and the use of the two properties under the actual application conditions. Long-term exposure to outdoor coupons and accelerated weather resistance experiments in laboratory simulation use environments are widely used to assess the life of color-coated panels. However, due to the disagreement with the measurement standards of the experimental results, the complexity of the environment, and the difference in the angle of understanding of the life of the color-coated plate, the measurement results of the Jiayuguan color steel plate can only explain or infer the probability life of the color-coated plate under a specific environment. .
The life of color-coated panels based on the performance life of the coating film The weather resistance of color-coated panels mainly depends on the physical and chemical properties of the coating film. In the foreign paint industry data, it has been proposed that the durability of color-coated plates refers to the interval before the coating film is severely hardened and chalked.
