Caitu life on different metrics, the results are inconsistent. In fact, paint or color coating manufacturer and color-coated applications due to their different perspectives department for evaluation of life measure requires naturally not entirely consistent. Take the above two kinds of life, for example color steel roll, compare our Baosteel, two used in the project is about 600,000 square meters of color coated (Japan) corroded. Baosteel 1993 survey results show that: a project with a color-coated corrosion rate of about 0.3%, on the inside of the harshest climatic environment at 1% (acrylic resin); Phase II project, the even color-coated polyester casting, hot rolling mill for five years, the corrosion rate of about 0.3 percent. So far, these have been used for color-coated about 12 to 15 years, although has far exceeded the first period of the life of the concept, but has also been in use. The fact can be explained using the above color-coated, color-coated life under normal environment should not be a problem. However, when the design selection, processing and use must be based on working conditions, the right to select the appropriate substrate and coating color steel appliances varieties, which is the useful life of a reliable guarantee. Analysis from the base coat color coated structural characteristics and mechanism on the life of color-coated essentially means that in practice the good working conditions Which color steel, corrosion resistance and color-coated substrate Apply weathering game where volumes sold Color, limit the use of two properties of a unified expression. Room plug-piece long-term exposure and laboratory simulation environment to accelerate the performance of anti-climatic test methods are widely used to assess the life of color-coated. However, due to the results do not agree with metrics, complexity of the environment, understanding the life of color-coated angle differences and other factors, the measurement results can only explain the life of a particular environment or presumed probability caitu under. To film the performance criteria of life for the life of color-coated anti-climatic performance of color-coated coil coating film depends on the physical and chemical properties. Data reported in the paint industry abroad, have raised the durable life of color-coated film refers to a serious hardening, chalking the previous interval.
