The difference between color coated plate and color steel plate

The difference between color coated plate and color steel plate

Color coated steel plate is made of cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating with paint in a continuous method (roller coating method), baking and cooling. The product. Color steel plate refers to color-coated steel plate, which is a steel plate with organic coating. Color steel plate is divided into single plate, color steel composite plate, floor deck and so on. The specific differences are as follows: 1. During the refining process, the base plate of the color-coated plate is a steel strip used for coating paint. The treatment of the front and back of the color-coated plate is extremely important. Usually, the color, coating performance and surface High quality requirements. The color-coated plate has strong hardness and flexibility. Its coating resists mechanical effects such as scratches, friction, collision, and press-in. The coating of the color-coated plate and the substrate are deformed together without damage. . Color-coated boards start from the end of production, when the performance of the original coating drops to the interval that must be overhauled to maintain its protective effect on the substrate. Under the influence of use and over time, it will gradually age, so a major repair must be carried out to make its durability longer. 2. The color steel plate is a cold-rolled steel plate as the base material. After degreasing and phosphating treatment, double-sided hot-dip galvanizing is performed under the protection of nitrogen. After applying a chemical conversion film that is easy to adhere to the primer, Painted with epoxy resin primer and painted with chemical-resistant color topcoat to shape him. The color plate is a colored steel plate, which is coated with a layer of polymer material on the steel plate. There are single-sided and double-sided. Most of them are single-sided, and the surface can also be printed with patterns. The above two major points are the difference between color-coated plates and color steel plates that we often understand. When we choose to use, we must choose the products we need according to our actual situation. If you have any needs, you can contact us at any time.

Process flow and main purpose of color coated board

Process flow and main purpose of color coated board

Color coated plate, also known as color steel plate, color plate in the industry. Color coated steel plate is made of cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating with paint in a continuous method (roll coating method), baking and cooling Into the product. Coated steel plate has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc. Good results such as wood, construction, energy saving, and pollution prevention. Production Process: The main production processes of the common two-coating and two-baking continuous color coating unit process flow are: Uncoiling machine-sewing machine-pressing roller-tension machine-uncoiling looper-alkali degreasing-cleaning ----Drying-------passivation-------drying------primary coating-------primary coating drying------surface Lacquer fine coating------top paint drying------air-cooled cooling------winding looper-----winding machine-----(the next volume is packed into Library). Product Usage: The color-coated steel plate using galvanized steel plate as the base plate, in addition to zinc protection, the organic coating on the zinc layer has a covering and isolation function, which can prevent the steel plate from rusting, and has a longer service life than galvanized steel plate. The service life of steel plate is 50% longer than that of galvanized steel plate. However, in different regions and different parts of use, the service life of color coated sheets with the same galvanizing amount, the same kind of paint, and the same coating thickness will be very different. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate increases and the service life is affected. In the rainy season, the coating will be corroded quickly and the service life will be reduced if the coating is wetted by rain for a long time, or where the temperature difference between day and night is too large and easy to condense. Buildings or workshops made of color-coated steel plates often have a long service life when they are washed by rain, otherwise they will be affected by the effects of sulfur dioxide gas, salt and dust. Therefore, in the design, if the slope of the roof is larger, it will be less likely to accumulate dust and other dirt, and the service life will be longer; for those areas or parts that are not frequently washed by rain, they should be washed regularly with water. Home appliances: 31% Construction: 63% Others: 6% Color steel plates are widely used. It has excellent weather resistance, corrosion resistance and high processing characteristics. Color steel plates are widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical treatment, automobile industry, etc. Quality characteristics: 1. Economical The production process of color-coated steel plate is less harmful to the environment, and can be recycled, which greatly reduces environmental pollution, and has a lighter weight, which can save load-bearing structural materials and reduce manufacturing costs. 2. Convenient processing and construction Color-coated plates can be rolled into profiled steel plates of various shapes and lengths according to needs, generally without overlap in the middle, simple construction and good waterproof effect.

Specification requirements for printing plates

Specification requirements for printing plates

In general, the printing plate can be selected according to the standard color of the manufacturer, which can shorten the workload in the early stage of production. If special colors are needed, the paint will be first configured in the paint factory for sample configuration and can only be produced when the various properties meet the requirements, so the production time from ordering to printing color coated panels will be longer. The surface gloss of the coating measured with a reflection angle of 60 degrees. The larger the value, the higher the gloss. The medium gloss and matt gloss of the paint used on the building are between 30-55. This is because high-gloss coatings used in buildings reflect strong sunlight and are dazzling; if they are indoors, they can easily cause visual fatigue at night under lights. The coating film of the printed color coated plate is made of baking synthetic resin paint. When used outdoors, the coating film will gradually deteriorate due to the influence of sunlight, temperature and rain. Observe the surface of the steel plate carefully or touch it with your fingers. White powder can be found. This phenomenon is the chalking of the coating film, which is inevitable. However, choosing different types of coatings can delay the age of chalking. In addition, the service life is different in different areas such as coastal areas, industrial areas and rural areas. Once there is corrosion such as chalking and cracking of the coating film, it should be repainted to extend the service life.
