From the life of color-coated base coat color coated structural characteristics and mechanism of the analysis, in essence, means that in the practical application of working conditions, weather resistance and color-coated corrosion resistance of two organic film kinds of performance limits the effective use of the unified expression. Use extreme measure is not unified, consistent with the concept of life will be impossible. Life of color-coated, specification uses in a variety of corrosive media and atmosphere typical working conditions of long-term exposure to indoor plug-piece test, combined with laboratory simulation environment to accelerate anti-climatic performance test results of two comprehensive assessment made. Even so made life data, only instructions or speculate on the set of conditions the probability of life environmental conditions, and the actual life of color-coated in buildings still have gaps. In some foreign sources, and has proposed a durable life of color-coated film refers to severe hardening, chalking previous time, meaning within the specified number of years does not crack, not falling. So color coated paper, with different types of paint production of color-coated coil prices Shandong painted, its life is also different. According to data reported Baosteel, all kinds of paint under the same conditions (urban environment) painted the picture roll, its life is shown in Table 4-8-11. According to the British Imperial Chemical Industries (ICI) coil coatings product information on the life expectancy of its typical products are shown in Table 4-8-12. Also, according to data reported for outdoor use due to color-coated, erosion by pollution and climate conditions change, when the organic coating may cause long-term sun exposure were hardened and chalking, swelling due to moisture and to the hole and painted pine volume fraction Article, the final film gradually lose the protective effect, the need for repainting maintenance processing. In the time before this deal as a concept of life is life. According to this concept, foreign to today's level of development of the paint that is possible to determine the coating color coated in some heavily polluted climate of a lifetime of 20 years, the rural areas of 30 to 40 years.
