The production of stone patterned color coated rolls mainly includes the following process:
Substrate preparation
Firstly, choose a suitable metal substrate, usually cold-rolled steel plate or galvanized steel plate. These substrate surfaces should be flat and free of obvious defects to ensure the quality of subsequent coatings and the integrity of the stone pattern.
Preprocessing
Degreasing treatment: Remove grease from the surface of the substrate, as grease can affect the adhesion between the coating and the substrate.
Chemical conversion treatment: such as phosphating or chroming treatment, forms a conversion film on the surface of the substrate, enhances the adhesion between the substrate and the coating, like creating a good "adhesion foundation" for subsequent coatings.
Stone pattern printing
Adopting advanced printing technologies such as gravure printing or digital printing. By using high-precision printing equipment, the designed stone pattern is printed onto the preprocessed substrate. Use specialized ink to ensure the clarity, color saturation, and realism of the stone pattern, making it close to the texture effect of real stone.
Painting
Apply a layer of protective paint on the substrate printed with stone patterns using methods such as roller coating or spray coating. The main function of this layer of paint is to protect the stone pattern and substrate, enhance corrosion resistance and weather resistance. The choice of coating will be determined based on the specific purpose of the product, for example, for outdoor stone patterned color coated rolls, UV resistant and rainwater resistant coatings need to be selected.
solidification
The painted color coated roll enters the curing furnace and is heated to quickly dry and cure the coating. The curing process requires strict control of temperature and time to ensure that the hardness, wear resistance, and other properties of the coating reach their optimal state.
Cooling and winding
The cured stone pattern color coated roll is cooled by a cooling device to reduce its temperature to a suitable range, and then rolled up for storage and transportation.
The main uses of stone patterned color coated rolls are as follows:
Building exterior wall
Used for commercial buildings such as shopping malls, hotels, office buildings, etc., it can create a high-end and stable architectural appearance, imitate the texture and texture of natural stone, and enhance the overall image of the building. For example, using it on the exterior of a large shopping mall can make the building look more stylish.
For residential buildings, especially villas or high-end residences, stone patterned color coated rolls can bring a stone like decorative effect to the walls, which is both beautiful and has good protection. Compared with natural stone, the cost is lower and the installation is more convenient.
Interior decoration
As a background wall material, whether in living rooms, bedrooms, conference rooms, or other places, stone patterned painted rolls can be used to create a natural stone style background wall. It has a variety of stone patterns to choose from, such as marble patterns, granite patterns, etc., which can meet the needs of different decoration styles and add natural and artistic atmosphere to the interior.
It can also be used for indoor partitions, creating a visual effect of stone while dividing the space, making the space look more exquisite.
Industrial buildings
In industrial plants, warehouses, and other buildings, stone patterned color coated rolls are used for exterior wall decoration. They not only beautify the appearance of the building, but also resist corrosion and pollution in the industrial environment, protect the building structure, and extend the service life of the building.
