Prepainted Aluzinc Steel Coil have long been recognized by the public, and its ease of use and applicability are all very good. Many manufacturers pay attention to the development prospects of this product, and then there will be a variety of goods, then customers are choosing color. When you roll the film, you will have doubts. How to choose the color coating method properly, which methods to use to choose the right product, look forward to helping you worry!
For the Prepainted Aluzinc Steel Coil, the development trend in recent years is equivalent to strong, the demand for this product will increase over the years, but there is a lack of excellent substrates such as zinc-free flower screed and zinc alloy coated rolls. The types and quality of domestic architectural coatings can not completely meet the requirements. The high price of imported architectural coatings reduces the competitiveness. The plastic molds required for the colorful glass membranes need to rely on imported materials, lacking coating thickness, versatility, high toughness, A variety of high-end color coated rolls. Therefore, when people choose products, they must pay special attention to observing the relevant characteristics of the products. Knowing the latest news of the products is of great help to people purchasing goods.
Surface scratching is the surface defect of the product when the Prepainted Aluzinc Steel Coil, is produced and processed. It not only damages the appearance of the color coated product, but also reduces the corrosion resistance of the scratched color coated product. It can be divided into raw material scratches and production. Scratch in the processing and production process. Scratch on the surface of the raw material. Refers to the quality defects caused by the hot-dip galvanizing production and processing of the base steel plate. The use of the scratch-resistant base steel plate to produce and process the color-coated coil is easy to produce and process the color coating. The surface of the aluminum plate causes the color deviation to cause the quality defect of the leakage coating. The control method is to check the quality of the production process in the production process, and prevent the raw material-based steel plate with scratches from entering the factory.
Prepainted Aluzinc Steel Coil coating refers to such quality defects caused by the application of industrial coatings on carbon steel sheets during the production process of color coated coils. It is the most common product quality defect in the production and processing of color coated aluminum sheets. It not only immediately hurts the appearance of the color coated goods, but also hurts the performance parameters of the color coated aluminum sheet products. It also reduces the corrosion resistance of the color coated coiled goods, and loses the characteristics that the colored coated aluminum sheets should have. Therefore, everyone It is essential to understand the causes of leakage during the production process, so you can use the most effective precautions to avoid and control the leakage defects.
In the high-temperature transportation, put each color-coated aluminum plate directly into the moisture-proofing agent, or open the small hole on both sides for the air permeability, or place the smoke-proof system to avoid the occurrence of high temperature and water droplets during transportation. The dialysis causes a diazotization reaction. The Prepainted Aluzinc Steel Coil encounter many difficulties during the whole process of transportation. If this problem is solved, the safety factor can be sent to the consumers.
