Caitu in the baking process, the board temperature gradually increased, so that the volatile solvent in the paint to gradually complete crosslinking. Due to the curing oven temperature can be controlled separately for each segment, thus allowing the strip through different temperature curve eventually reach PMT value. But usually control paragraphs 1, 2 lower strip temperature furnace, so that the film can be fully solvent to evaporate before oven curing, if heated too fast, too fast in the coating solvent Color overflow volume, or The volatile solvent paint film had a chance to solidify Color volume Which is good, cause surface defects such as bubbles. In the furnace 3, paragraph 4 of the color steel manufacturer, strip temperature slightly higher than the paint curing temperature. When the strip enters paragraph 3 Boxing color steel color steel coil, basically evaporate the solvent, when the film begins to solidify. In this case mainly chemical drying process, coating the polymerization reaction, a hot air circulation should be strengthened, to accelerate the reaction; however, if the wind speed is too large, will destroy the balance of the film in various stages of formation, prone to wrinkles and other defects gloss reduction . In paragraph 5 of the furnace, the strip temperature slightly lowered or unchanged. If the temperature of the same segments, namely strip temperature linear upward trend, although guaranteed to reach the final curing temperature strip, but the time is too short at this temperature, low crosslink density, and thus make the wear resistance, solvent resistance, etc. are deteriorated. Melamine resin and a mixed resin coating, acid gas furnace (hydrogen peroxide, sulfur dioxide, carbon dioxide) will occur in the coating surface contact reactions, easy to produce wrinkles, parted and other defects. Powder coated color coated coating thickness in the range of 10 ~ 250μm, the wide range of its products used in construction, light industry, household appliances, furniture, computers and so on. 4 foil method pretreatment before coating film method and a roll coating method is basically the same, under pretreatment strip coated with back paint, thermosetting adhesive coated on the surface, the activation process will be PVC plastic film bonded to the substrate on the surface, cooling, flatten, gained the appearance of beautiful color film board. Some painted unit is dual roller coating and film crew, in the same unit, the two processes were available production roll coating and film are two types of color-coated. Color coated film appearance beautiful, with excellent fire resistance, corrosion resistance, anti-acid and other properties, fire resistance, stain resistance with good. But higher prices, its products are mainly used in home appliances, furniture, interior decoration and travel interior.
