What is the difference between spray paint and baking paint on automobile hubs?

1. The paint film is different: the edges and corners of the paint are smooth and the color is the same. It proves that the paint film is uniform and the color is full. The corners of the paint are rough, and the color is lighter than the door panel. It proves that the paint film is uneven and the color is not full. The difference between grain: the surface of the baked paint door panel is smooth, without grain, and no orange peel. The surface of the spray-painted door panel is textured, not smooth, and orange peel.

2. The adhesion of baking paint is stronger than that of spray paint, and there is also a layer of varnish to protect the wheel hub, making the surface of the wheel hub more wear-resistant.

3. Good spray paint! The texture of the spray paint is good, and the use time is relatively long. It generally takes 5-6 layers to achieve the expected effect when the amount is large, while the spray paint only needs to be sprayed twice and the good imported spray film. Cold and hot alternate for up to two years. In general, it will be brittle in a few months to a year and a half. If the spray paint does not rub, it can usually be maintained for 5-6 years without discoloration.

4. Generally, automobile paint is baked paint, and the surface treatment process of the hub can be divided into two types: baking paint and electroplating.

5. Whether the repair of the hub spray paint is reliable or not depends on the situation. If it is a large-area repair, there is no repair, but a small area is fine: the hub is also called the wheel rim.

CarThe difference between car baking paint and piano baking paint

Piano paint is much higher than car baking paint in terms of brightness, density, especially stability. If mechanical damage occurs, the surface layer of piano paint is still as bright as new after many years, while ordinary brightness spray paint has long been oxidized and penetrated.

The difference between piano baking paint and ordinary baking paint is that piano baking paint is made of high-grade paint, which has higher gloss and wear resistance, and can maintain beauty for a long time. The coating of piano baking paint is thicker, which can effectively protect the surface of the piano and prevent scratches and damage.

The cost is different. The piano baking process is complex, the cost is high, and the price is expensive. The ordinary baking paint process is relatively simple, the cost is lower than that of piano baking paint, and the price is relatively cheaper.

The paint materials of the two are different, and the display effect of the finished product is also different.Piano baking paint is based on high-grade environmentally friendly double-stached medium-density fiberboard, and high-quality environmentally friendly polyester paint is used as the topcoat. The finished product effect is comparable to the high-quality piano surface.

How long does it usually take to bake car paint

1. Car baking paint rooms usually bake for 30 to 60 minutes. When the car is painting, it usually takes about 30 minutes to 60 minutes from the moment it enters the baking room. At present, when the car paint surface is repaired, the spray paint used is mainly self-drying paint. In the later stage, it needs to be baked at low temperature to make the spray paint surface more stable.

2. Generally, it will be completely dry, especially within 24 hours. First of all, hand over the car to the professional car painting center, the service consultant will receive it, and communicate with the car owners about the painting part.And the price, and after the full inspection and confirmation of the vehicle, it will take about 1 hour to open the bill and hand over the construction order to the workshop.

3. Generally, if it is serious, it will take one day. If it is not serious, it will take about half a day. The original high-temperature baking paint of the car is generally enough for half an hour per coating. The repair paint is self-drying, and it can be baked for half an hour to 1 hour at a low temperature of 6-80 degrees in the baking room.

4. For ordinary paints, the drying time of baking paint generally takes between 30 minutes and 1 hour. However, for high-end baking paints and special paints, the drying time may be longer, more than 1 hour, or even 2 to 3 hours.

Does car spray paint need to be baked dry

, no need to bake, car spray paint is reinforced with self-drying paint, it takes four hours to dry after painting, and it takes 48 hours to dry completely dry, but it only to dry faster. The baking paint room is generally only used for painting. There is a supply and exhaust air system to improve the environment of painting and painting. I hope it can help you.

Car spray paint needs to be dried, otherwise the paint surface cannot be completely cured. The adhesion of the paint surface that has not been completely cured is relatively poor, so the car needs to be parked in the paint spraying room for painting after painting. Only in this way can the paint surface be completely cured. In fact, there are many layers of body paint. The body paint consists of four layers, and each layer of paint has different functions.

In fact, car spray paint must be baked dry after application. This is because the coating after painting needs to be cured at high temperature, so that the color is more vivid and light.It is brighter, and it can also enhance the hardness and adhesion of the paint film, so as to better protect the car body.

Does the car spray paint still need to be baked (does the car spray paint need to be baked?) The car spray paint needs to be baked, otherwise the paint surface cannot be completely solidified, and the adhesion of the paint surface without complete solidification is relatively poor. Therefore, after spraying the paint, the car needs to be parked in the baking paint room to bake the paint, only in this way can the paint surface be completely solidified.
