1.Color coated substrate type

Color coated cold rolled base plate

The color plate produced by the cold-rolled substrate manufacturer is smooth and beautiful in appearance, and has the workability of cold-rolled plate. However, any small scratch on the coating surface will expose the cold-rolled substrate to the air, resulting in the rapid formation of red rust. On bare iron. Therefore, these products can only be used for temporary isolation measures with low requirements and can only be used as indoor materials.

Hot dip galvanized color coated roll

Organic coating on hot dip galvanized steel plate is the product of hot dip galvanized color coating plate. In addition to the protective effect of zinc, the organic coating on the surface of hot-dip galvanized color coated board also plays a role in isolation and rust prevention, and its service life is longer than that of hot-dip galvanized board. The zinc content of hot-dip galvanized substrate is generally 180 g/m2 (double-sided). The zinc content of outdoor hot-dip galvanized substrate is 275 g/m2.

Hot dip galvanized color coated roll

Hot-dipped aluminum-zinc plates can also be used as color coating substrates (55% aluminum-zinc and 5% aluminum-zinc) upon request.

2、Color coating board process

Color coated plate is a production process of the longest products, better components to be obtained from iron to steel, and specific thickness, width and plate type need to be made from hot rolling to cold rolling process, and then after annealing, galvanizing and color coating, to form colorful color coated plate. The production process of baosteel color coating unit includes: uncoiling - stitching - degreasing - pretreatment - initial coating - initial coating baking - initial coating cooling - fine coating - fine coating baking - fine coating cooling - quality control - pressing - rolling - rolling.

The most critical and important production processes include pretreatment, coating and baking. The pretreatment process is to remove impurities and oils from the surface of the substrate after cleaning, and through the treatment of composite oxidation and passivation, the pretreatment film process is thus line. This is an effective means to improve the adhesion between substrate and coating.

3、What are the end users of color plate rolls?

Roller coating is a coating method in which the coating on the plate is brought to the coating roller by the belt roller, and then the wet film is transferred to the surface of the strip steel. This way is fast, high production efficiency; No fog, coating efficiency is close to 100%; The coating thickness can be increased or decreased in a certain range by adjusting the clearance, pressure and rotating speed of the stick. You can apply one or both.
