Color-coated rolls are products that form a colored coating on the surface of metal or other materials by applying colored paint. It is widely used in construction, home appliances, automobiles and other fields, and has the advantages of beauty, durability and anti-corrosion. The following is the production process of color-coated rolls:
Color-coated rolls are products that form a colored coating on the surface of metal or other materials by applying colored paint. It is widely used in construction, home appliances, automobiles and other fields, and has the advantages of beauty, durability and anti-corrosion. The following is the production process of color-coated rolls:
1. Material preparation: Select a suitable base material, usually cold-rolled steel plate or galvanized steel plate. The substrate must undergo cleaning, oil removal, surface treatment and other processes to ensure that the surface of the substrate is clean and smooth.
2. Paint preparation: Select appropriate color paint according to needs. Paint generally includes primer, topcoat and protective paint. According to the formula, various coating raw materials are mixed in a certain proportion, and a uniform coating is obtained through stirring, dispersing and other processes.
3. Coating process: The substrate is fed into the coating line. After pretreatment, the coating is evenly coated on the surface of the substrate through roller coating, spraying, etc.
4. Drying treatment: After the coating is completed, the coated substrate is sent to an oven or high-temperature furnace for drying treatment. Drying temperature and time are determined according to the type and thickness of the coating to ensure the quality and adhesion of the coating.
5. Coiling and cutting: After the coating is completely dry, roll the color-coated roll through a coiler to form a large roll. Large rolls can be further cut into color-coated sheets of different widths and lengths as required.
6. Inspection and quality control: Inspect the cut color-coated sheets, including appearance, thickness, adhesion, etc. Ensure products meet relevant standards and requirements.
7. Packaging and storage

The difference between austenitic stainless steel and martensitic stainless steel
Martensitic stainless steel is a relatively common classification of stainless steel materials. The application of this type of stainless steel material is particularly convenient, especially in welding. Martensitic stainless steel is particularly favored by users. The processability of martensitic stainless steel when heated is particularly outstanding, and this is recognized. Martensitic stainless steel is often compared with austenitic stainless steel, which are the two more common stainless steels.

What material is carbon steel?
Carbon steel, also called carbon steel, is an iron-carbon alloy with an internal carbon content of close to 2%. In carbon steel materials, in addition to containing carbon elements, there are many other components, such as elements, sulfur elements or silicon elements. Generally speaking, if the amount of carbon contained in carbon steel is relatively high, the harder it will be, resulting in The intensity will be higher. Just be aware that the higher the carbon content, the lower the plasticity will be.
