720mm 220v 1500w Clear Carbon Fiber Heating Lamp For Car Printing Baking machine from Goldisgood applciation
The following is the application of 720mm 220v 1500w Clear Carbon Fiber Heating Lamp in car printing baking machine:
Preparation before car printing
Preheating the body surface: Before car printing, it is necessary to use this heating lamp to preheat the body surface. Heating can remove moisture and impurities on the body surface. For example, in humid weather, the body may absorb some water vapor, and preheating can make the water vapor evaporate quickly. Moreover, proper preheating can increase the surface temperature of the body, which helps the subsequent printing ink to adhere better and enhance the bonding between the ink and the body surface.
Adjusting surface tension: The car body is usually made of metal or composite materials, and its surface tension affects the spreading of ink. The heat of the heating lamp can adjust the surface tension of the body to a certain extent, so that the ink can be spread more evenly during printing, reducing the shrinkage or accumulation of ink, thus laying the foundation for obtaining high-quality printing effects.
Application in the automobile printing process
Accelerate ink drying: In the automobile printing process, the use of this heating lamp can accelerate the drying speed of the ink after each printing step or layer of ink is completed. The power of 1500w can provide enough heat to make the solvent in the ink evaporate quickly, thereby shortening the waiting time between each layer of ink and improving the overall efficiency of automobile printing. For example, in the printing of automobile patterns with multi-color overprinting, the fast-drying ink allows the printer to print the next color faster and reduce the mutual interference between colors.
Improve ink leveling: After the ink is printed on the surface of the car body, the continuous heating of the heating lamp can keep the ink fluid, thereby improving the leveling of the ink. Good leveling can make the ink surface smoother, reduce the orange peel phenomenon and ink granularity, and make the printed pattern clearer and more delicate. For some inks containing metallic pigments or pearlescent pigments, improving the leveling can also make these special pigments better distributed and show better visual effects.
Baking and curing after automobile printing
Enhance the curing effect of ink: After the automobile printing is completed, the car body is baked by the heating lamp in the baking machine, which can effectively enhance the curing effect of the ink. Heating causes the resin and other components in the ink to undergo a cross-linking reaction, forming a more solid film layer, which improves the hardness, wear resistance and chemical resistance of the ink. The cured ink can better resist various environmental factors faced by cars in daily use, such as rain erosion, sun exposure, road dust, etc., and extend the service life of the car printing pattern.
Improve color stability: During the baking and curing process, the heating lamp helps stabilize the color of the ink. By promoting the full reaction and arrangement of the ink molecules, the printed color is made more vivid and lasting, avoiding the problem of color change or fading caused by incomplete curing of the ink. This is very important for the long-term aesthetics of the car’s appearance, especially for some car printings with brand logos or artistic patterns.
