Description
Technical field
The utility model relates to the servicing unit of paint work unit in a kind of Bus in Color Coat Production Line, particularly the paint feedway of paint work unit in a kind of Bus in Color Coat Production Line.
Background technology
Coil Coating Products, claims again color steel, colored steel.Coil Coating Products has cold-rolled steel sheet or galvanized steel plain sheet substrate, and Coil Coating Products is with rolling method, to apply continuously one or more layers paint on the front and back of substrate in Bus in Color Coat Production Line, through the unit process such as drying and cooling, makes.In Bus in Color Coat Production Line, mainly contain the operation units such as uncoiling, surface treatment, japanning, oven dry, cooling, rolling, be that liquid state paint is coated on the plate face of substrate continuously by the method for roller coat in paint work unit.
Paint raw materials are that the material of main part of paint is macromolecular material with the liquid of metal bucket splendid attire, and the viscosity of usually oil raw materials for varnish is larger.Directly with the larger paint raw materials of viscosity, be not suitable for continuously in coating of substrates operation, also can cause coating inequality and unnecessary overweight coating, the technique that the viscosity pole earth effect of paint paints with rolling method continuously coating on substrate and the quality of Coil Coating Products, in order to improve processing performance and the product quality of paint, before japanning, regulate the viscosity of paint raw materials, make the viscosity of paint raw materials be applicable to the coating operation on substrate continuously.
In order to reduce the viscosity of paint raw materials, in prior art, be to add diluent in the larger paint raw materials of viscosity, with the diluent adding, reduce the viscosity of paint raw materials, make it to be applicable to the coating operation on substrate continuously.
