Introduction to the use and maintenance of color coated panels

Reasonable material selection can meet the requirements of use while reducing costs to a limited extent. Irrational material selection can lead to increased costs or substandard products. Therefore, customers should attach great importance to the importance of reasonable material selection. Shandong Guanzhou provides pre-sales technical services and puts forward professional opinions and suggestions on the customer's material selection.

1. The indicators of color coated plate material selection mainly include: mechanical properties, substrate type and coating weight, front coating performance and reverse coating performance.

2. The selection of mechanical properties is mainly based on the use, processing method and degree of deformation. When selecting materials, the strength, formability and load-bearing capacity of the prepainted plate should be considered. Common processing methods include shearing, bending, rolling, etc., so they should be considered comprehensively when selecting materials. In addition, it should be noted that increasing the mechanical properties and storage time of the prepainted plate may change.

3. The choice of substrate type and coating weight is mainly based on the use, corrosiveness of the use environment, service life and durability. The weight of the coating should be determined according to the corrosiveness of the use environment, and the substrate with good corrosion resistance and large coating weight should be used in a highly corrosive environment to ensure the specified service life and durability.

4. The selection of frontal coating performance mainly refers to the selection of coating type, thickness, color difference, gloss, hardness, flexibility/adhesion, durability and other properties. The performance of the reverse coating is usually selected by the supplier according to the use and use environment. In general, in terms of coating durability, polyvinylidene fluoride > high durability polyester> silicone-modified polyester > polyester.

5. In general, hot-dip 55% aluminum zinc and galvanized aluminum magnesium substrate have better corrosion resistance compared with hot-dip galvanized substrate, but 55% aluminum zinc substrate should be used with caution in alkaline environments.

6. Ceramic factories, pickling workshops, electroplating workshops, paper workshops, dyeing rooms, tanning workshops and other special environments with high corrosiveness, as well as chemical plants, smelters, gas generators, thermal power plants, brewing workshops, steam environments, industrial dust environmental pollution places. It is recommended to choose 1000% high-zinc aluminum-zinc or galvanized aluminum-magnesium substrates within 55 meters of heavy industrial areas and coastlines.
