Cost-effective color coated steel plate!

Color coated steel plate is a product made of cold-rolled steel plate and galvanized steel, zinc aluminum magnesium, and galvanized steel plate as the base material, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), and continuous painting (roll coating method), by baking and cooling. The coated steel plate has light weight, beautiful appearance, good anti-corrosion performance and can be directly processed.

It provides a new kind of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical appliance industry, etc., and plays a good role in replacing wood with steel, efficient construction, energy saving and consumption reduction, and pollution prevention.

Cold-rolled steel strip and galvanized steel strip (electric galvanized and hot dip galvanized) as the substrate, on the continuous unit, after the surface pretreatment (degreasing and chemical treatment), with a roll coated with one or more layers of liquid paint, after baking, cooling the sheet is the coated steel plate.

Domestic back (bottom) paint and top (front) paint two kinds of paint. In general, China has one coat of back paint and two coats of top paint. For the top paint of foreign enterprises, there are two layers of back paint. Because the coating can have a variety of colors, it is customary to call the coated steel plate color coated steel plate.

The development trend.

1. The use of high-quality substrates, the surface, shape and dimensional accuracy of the substrate is increasingly required. Outdoor use of small zinc-coated flat hot-dip galvanized steel coil, non-zinc-coated flat hot-dip galvanized steel coil, and the emerging zinc alloy hot-dip galvanized steel coil. For indoor use, such as electrogalvanized steel coils, thin-film coated cold rolled sheets and aluminum coils.

2. Improve the pretreatment process and the pretreatment liquid, so that the number of equipment is small and the cost is low to become the mainstream process, and the stability, corrosion resistance and ecological environmental protection performance of the pretreatment liquid are constantly improved.

3. Pay attention to the development of new coatings, improve general polyester, polyvinylidene fluoride (PVDF) and plasticizing sol, obtain super color reproduction, ultraviolet resistance, sulfur dioxide resistance, and improve corrosion resistance. Develop functional coatings that are resistant to pollution and heat absorption.

4. unit equipment is more perfect. Such as the use of new welding machine, new roller coating machine, perfect curing furnace, as well as advanced automatic instruments.

5. Because the cost of cold-pressed flowers is lower than that of hot-pressed flowers, and it has the characteristics of beautiful appearance, good three-dimensional effect and high strength, the production technology of cold-pressed flowers has become a development trend.

6. Pay attention to the diversification, functionalization and high-grade of products, such as self-cleaning color coated plate, high aluminum zinc aluminum magnesium color coated plate, fluorocarbon color coated plate, animal husbandry environment special color coated plate, etc.

Color coated board has the characteristics of no pollution, excellent weather resistance, corrosion resistance, high processability, etc., and is widely used in construction, home appliances, transportation, packaging, machining, interior decoration, medical treatment, automobile industry and so on.
