Baking conditions on the color of the coat color affect the general colorimeter measurement, expressed ΔE value, when the color value is within a certain range to pass. ΔE is calculated as follows: in the light ΔE = [(ΔL) 2 + (Δa) 2 + (Δb) 2] 1/2 ΔL-- color system, the measured value of the dark direction; Δa-- color systems of red, green measuring direction value; Δb-- yellow color system, the measured value of the blue direction. To study the impact of curing condition on color, we put the paint into two categories: light-colored series and dark series. Pale gray with white paint series, for example; a dark navy blue paint series, for example according to Figure 4, Figure 5 shows: For light-colored painted products, such as lime, ivory, white light, with fine painted surface PMT (. Peak Metal Temperature, refers to the strip surface peak temperature rise), and color control system in the negative direction ΔL will develop, that the temperature increases, the color will be dim; For the dark in terms of color-coated paint, such as brown, black , navy, along with fine painted rose baking PMT, the color control system will be to the positive development of ΔL, ie the lower the temperature, the darker the color. The results also showed that: temperature control system in the color difference Δa, Δb little effect, color control in both directions mainly by topcoat dry film thickness control. Because visual color light-colored painted relatively sensitive to changes in the product, so for the same change in terms of color, light relative to the dark easier to identify, so we adjust the depth of the series painted products ΔL value by adjusting the PMT, in order to obtain more stable color change. When the light-colored painted products ΔL value prejudiced to, up five sections temperature increase PMT; on the contrary, when the light-colored painted products ΔL partial negative value, the lower the temperature five sections, reduce PMT. As a new type of material to be used widely, caitu already in construction, shipbuilding, vehicle manufacturing, the furniture industry, electrical industry and other industries have made outstanding contributions, and has played a good role, for example, efficient construction, energy conservation, pollution prevention and other effects. It is precisely because it is unique that makes its development in the industry is more rapid. So silver color coated, it will develop in the future to have a kind of it? The first color coating specifications, using high-quality substrate, the substrate surface, shape and dimensional accuracy requirements are rising Boxing caitu, outdoor use, such as the formation of small spangle galvanized steel coil, no spangle formation hot dip galvanized steel coil timely under the rise of hot-dip zinc alloy volumes; indoor use, such as galvanized steel coils, cold-rolled plates and aluminum foil roll. Second, to improve the pretreatment and pretreatment solution, a small number of devices, low cost technology to become mainstream, and continuously improve the stability, corrosion resistance, environmental performance pretreatment solution. Development caitu undoubtedly gave rise to very considerable prospects, which many in the industry but also to bring more opportunities, I believe that, with the continuous updating and development of technology, will continue to give each color-coated industry to bring more surprises.
