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, compare a country 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 percent Buying color coated on the inside of the harshest climatic environment at 1% (acrylic resin); the second phase, the polyester color coated plates for five years in continuous casting, hot rolling mill, its 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 of color-coated silver, 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. But in color-coated design selection must be based on the processing and use of working conditions, the right to select the appropriate substrate and coating species, which is the useful life of a reliable guarantee. The curing temperature color-coated steel sheet is determined by the characteristics of the coating, the coating must first reach the lowest temperature of the resin polymerization or crosslinking when baking insufficient curing, hardness and chemical properties of the coating was significantly reduced; but baking When too much, adhesion, gloss, T bending performance deteriorated sharply, the color yellow. Usually represented by the peak PMT paint curing temperature required to achieve good strip, typically 216 ~ 250 ℃, paint in the PMT specified range can give acceptable performance products, but vary within this range also make Coating performance to differ. Color is the color coating color coated unique performance specifications, representing the color standard plate coated products and differences in CIE standard colorimetric system by ΔE, baking curing temperature of the color effect of different colors on different, as shown in Figure 1 Fig. For lime, navy, etc. Most of the paint, in a certain temperature range (usually in the 224 ~ 241 ℃), color stable. For more sensitive crimson, baking curing temperature of great influence on the color, this is because the coating is usually added crimson organic pigment, poor stability, temperature sensitive, and therefore in the production of more crimson paint need to strictly control the curing temperature.
