Baking paint is a prototype surface finishing of metal.The method is: polished to a certain degree of roughness on the substrate, three times the primer, four times the topcoat. Each time the paint is applied, it is sent to a clean, temperature-free baking room and dried. The process currently requires high paint and good color rendering. About price of metallic paint varies depending on the fineness and color of the metal powder.
The paints are divided into two major categories. One type of low-temperature paint has a curing temperature of 140°-180°, and the other type is called high-temperature paint, and its curing temperature is 280°-400°. High-temperature paint, also called Polytetrafluoroetylene, referred to as Teflon, PTFE, F4 and so on. Teflon high-performance special coatings are fluorine coatings with PTFE as the matrix resin. The English name is Teflon. Because of pronunciation, it is often called Teflon, Teflon, Teflon, Teflon. Long et al. (all transliteration of Teflon).
1. Non-sticky: Almost all substances do not adhere to the Teflon coating. The very thin film also shows good non-adhesion properties. 2, Heat resistance: Teflon coating has excellent heat resistance and low temperature resistance. It can withstand high temperatures up to 300°C for a short period of time. It can be used continuously between 240°C and 260°C. It has a remarkable thermal stability. It can work at freezing temperatures without brittleness and does not melt at high temperatures. 3, Sliding: Teflon coating has a low coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.05-0.15. 4, Moisture resistance: Teflon coating surface is not exposed to water and oil, the production process is also not easy to dip solution, such as sticking a small amount of dirt, simple wipe can be removed. Shorter downtime saves hours and improves work efficiency. 5, Wear resistance: Under high load, with excellent wear resistance. Under certain loads, it has the dual advantages of wear resistance and non-adhesion.
6. Corrosion resistance: Teflon is almost free of chemicals and can protect parts from any kind of chemical corrosion.
Now do you know the difference between baking paint and spray paint ?
1. Technology
A, Baking paint:
Primer and topcoat on the substrate, each time the paint is baked.
B, Spray paint:
Through the spray gun or disc type atomizer, by means of pressure or centrifugal force, disperse into uniform and fine mist droplets, applied to the coating surface coating method.
2. Paint film
A, Baking paint: Smooth edges and corners, the same color. The front paint film is even and full of color.
B, Spray paint: Rough edges and corners. The front paint film is uneven and the colors are not full.
3. Texture
Practice: Control the light, look at the surface of the part to check if there is orange peel phenomenon.
Compared: A, Baking paint: The surface is smooth, no grain, orange peel phenomenon.
B, Spray paint: The surface has texture, not smooth with orange peel phenomenon.
4. Surface
Practice: Touch the surface of the metal prototype with dust and air bubbles.
Compared: A, Baking paint:The surface is smooth and flat.
B, Spray paint: Particles on the prototype surface, not smooth, touch a strange feeling.
5. Wear-resistant
Practice: Hit with a hard object.
Compared: A, Baking paint: No abnormalities, no damage to the paint film.
B, Spray paint: Cracks, severe paint film off, off the white skin.
All in all, the difference is:
The baking paint process is complex and requires high production environment, but the quality and effect are good! Because in the dust-free constant temperature room, there will be no spots on the surface caused by debris.
Spray paint (click here to know more) is equivalent to more flexible, such as on-site to do things, not energy production, it is impossible to get the clean room temperature inside the paint. Because of the site's reasons, the paint surface may have a tingling effect. If the weather is not good, it will have an effect on the paint. There is also important workmanship on the workers!
