The color board produced by the cold-rolled substrate through the color coating production line has a smooth and beautiful appearance, and has the processing property of cold rolling plate.But any small scratch on the surface of the coating would expose the cold rolled substrate to the air, causing it to rust quickly.Therefore, such products can only be used for temporary isolation measures with low requirements and for indoor materials.Send InquiryChat Now
The color coating production line is mainly used for the production and processing of color painting board, color painting board, industry also known as color plate, color board.Color coating steel is cold rolled steel sheet and galvanized steel substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), with the method of continuous coated with paint (roller coating method), after baking and cooling and manufactured products.Coating on the steel plate has a light weight, beautiful and good anti-corrosion performance, and can be directly processed, it to construction, shipbuilding, automobile manufacturing, household appliances industry, electrical industry provides a new type of raw materials, such as the steel for wood, such as efficient construction, save energy and prevent pollution.Caitu basic concept: in a row on the crew with cold-rolled strip steel, galvanized steel strip (electric galvanized and hot dipped galvanized) as substrate, after surface pretreatment (skim and chemical treatment), with the method of the roller coating, coated with a layer or multilayer liquid coating, after baking and cooling of the proceeds of the plate is the coating on the steel plate.Domestic has the back (bottom) lacquer and the surface (front) lacquer coating, generally domestic is the back lacquer one layer, the surface paint two layers, the foreign business surface lacquer back lacquer is two layers.Because the coating can have a variety of different colors, it is customary to call the coated steel plate color coated steel plate.
Use galvanized steel as substrate through color coating production line to produce color coated layer of steel, in addition to have the protection of the zinc, zinc layer of organic coating on the cover isolation function, can prevent the steel rust, longer service life than galvanized steel sheet, according to the service life of the coating on the steel plate to 50% longer than galvanized steel.However, in different areas and different parts of use, the use of the same coating with the same amount of zinc, the same coating and the same coating thickness will make a big difference in the service life.For example, in industrial areas or coastal areas, due to the effects of sulphur dioxide gas or salt in the air, corrosion speed is accelerated and life expectancy is affected.In the rainy season, the coating is soaked by the rain for a long time, or the area where the temperature difference is too large and easy to be exposed at night and day, it will be corroded faster, and the service life will be reduced.Buildings or workshops made of colored coated steel are often used for long periods of time when the water is washed, otherwise they are affected by the effects of sulphur dioxide gas, salt and dust.Therefore, in the design, if the inclination of the roof is greater, the less likely to accumulate dust and other filth, the longer the service life will be.For those areas or parts that are not normally washed by rain water, wash them regularly with water.
