Color coated steel coil is a composite material made of strip steel after continuous chemical transfer treatment such as surface degreasing and phosphating on the production line, coated with paint and baked. The material has good decorative properties and corrosion resistance. It has become a commonly used building construction material in recent years. To ensure that the material is used well, we need to operate according to the correct production process, and we need to pay attention to the following details during the production process:
1. Different types of topcoats are also different in terms of hardness, flexibility, adhesion, durability, etc. The durability of polyester is average, but the hardness and toughness are good, and the price is moderate; the durability of silicon-modified polyester, The gloss and color retention are high, but the toughness is slightly lower; the high weather-resistant polyester is more cost-effective; the polyvinylidene fluoride has excellent durability, good toughness, but low hardness, few colors available, and high price. Therefore, during production, we can choose the appropriate topcoat according to the purpose of the color steel coil, use environment, corrosion, service life, durability, processing method, etc.
2. We can choose a suitable primer according to the production process, use, use environment, and matching relationship with the topcoat.
3. The thickness of the coating can be determined according to factors such as corrosion, service life and durability of the use environment.
If you want to improve the usability of materials, you must pay attention to these three details in the production process. I hope it can help everyone.
