Caitu natural exposure test, 1) in the use of color-coated industrial environments, should be fully taken into account the industrial fallout factors embedded in the coating. The results showed that, polyvinylidene fluoride products with the best performance in an industrial environment. The density and improved chemical stability of the coating color coated product is critical in industrial environments to improve service life. 2) When using color-coated in a marine environment, should be fully taken into account the impact of salt spray atmosphere. The results showed that, polyvinylidene fluoride products with the best performance in the marine environment. 3) selection of color-coated products, should take into account the color of color-coated for durability effects, organic pigments are generally more durable products, poor product inorganic pigments, and silver pigments must consider the ability of its acid . 4) In general, Tianjin color coated, color coated with a better ability to acid rain atmosphere is harsh environment ideal building material. 5) in China, Hainan test point is the best one can examine the location of color-coated durability, it also has the strongest ultraviolet radiation and corrosive atmosphere harsh ocean, different colors can be objectively evaluated in a short period of time , color-coated varieties resistance to environmental aging ability. Caitu influence on the measurement area: the larger the area to detect color-coated, the test results, the better representation caitu specifications, will also improve the detection accuracy. Thickness of the magnetic detection probe diameter is generally 1.5 mm, detection probe micrometer diameter 6.3 mm color coated Buying, microscope method of measuring the length of generally not more than 1 mm, and measuring the diameter DJH also a general law mm. Therefore, under the same conditions, these four kinds of detection methods micrometer assay results of the least volatile.
