Continuous color coated board production line (PPGI, PPGL)
The strip steel continuous color coating unit is to re-coat the paint film on the (aluminum) zinc or aluminum plate substrate to achieve further anti-corrosion and beautification effects and expand the scope of use of the product.
Raw material: galvanized steel coil (GI/GL), 800-1250mm×0.2-1.2mm
Unit process speed: 60-120mpm
Color coating process: two coating and two drying (building materials board), three coating and three drying (home appliance board)
The coating machine is designed with adhesive roller, metering roller and coating roller, which can precisely adjust the thickness of the paint film.
Set up a curing furnace and waste gas incineration waste heat utilization system, use fresh air (high-quality products) or flue gas (low-cost) to dry and cure the paint film, and burn off the volatile solvents in the paint to achieve the effect of environmental protection and energy saving .
