The main purpose of color-coated board

Prepainted steel plate is also known as prepainted steel plate and prepainted steel plate. Prepainted steel plate is a kind of prepainted steel plate. The product is painted by roller coating method, and the product is baked and cooled by transformation treatment. The substrates of color coated sheets include cold-rolled substrates, hot-dip galvanized substrates and electrogalvanized substrates, and galvanized substrates. The coating types of color coated board topcoat can be divided into polyester, silicon modified polyester, vinylidene fluoride, high weather-resistant polyester, etc. The production process has developed from one coating and one baking to two coating and two baking. There is also a three-coating and three-bake process. There are many colors of color coated plates, such as white gray, sea blue, orange yellow, sky blue, crimson red, brick red, ivory white, porcelain blue, etc. The surface state of the color coated board can be divided into ordinary coated board, embossed board and printed board. The market uses of color coated panels are mainly divided into construction, home appliances and transportation.

The color coated steel plate has beautiful appearance, light weight, good corrosion resistance, and can be directly processed, providing a new type of steel instead of wood, high construction efficiency, energy saving and pollution prevention advantages.

1. The color coating board is widely used and has the characteristics of no pollution, weather resistance, corrosion resistance and high processability. Color coated plates are generally widely used in industry, construction, home appliances, packaging, machinery and other fields. Involved in industrial aspects such as processing, transportation, interior decoration, medical and automotive.

2, the use rate of color coated plate in home appliances is 31%, and the use

in construction accounts for 63%, is indispensable in the construction industry, other aspects of the use less, about 6%, galvanized steel plate as the substrate coated plate has protection and isolation function, not only can prevent the steel plate from rusting, the service life is extended by 50% than before, but also has a stronger protective effect.

3. Different regions and use parts, even if the same amount of galvanizing, paint and the same coating thickness of the color coated plate are used, its service life is more different. In industrial and coastal areas, due to exposure to sulfur dioxide gas or salt in the air, the rate of corrosion will be accelerated, which will affect the service life. During the rainy season, coatings can corrode quickly after being wetted by rain for a long time, reducing their service life.

4. The buildings and factories of the color coated board, if they are often washed by rainwater, can extend the service life. Otherwise, they will be more susceptible to sulfur dioxide, salt and dust. Therefore, when designing, the inclination of the roof should be increased. The larger, the less dirt such as dust accumulates and the longer the service life. Areas and areas that are not often washed by rain should be cleaned regularly.
