Detailed explanation of the baking paint process

The detailed baking process is: every time the paint is applied to the substrate, it is sent to the dust-free constant temperature baking room for drying treatment, and so repeated three, four times or more. Four simple steps, primer, topcoat, transparent paint, waxing, and that's it.

The first step: First of all, choose the materials used. The materials and production processes of general lacquer furniture are basically the same as those of other wooden furniture. The frame of high-end lacquer products needs to be made of precious materials such as Nanmu, mahogany and rosewood, and carved with various exquisite patterns. Step 2: Apply gray. Apply ash.

Process: A. Baking paint: apply primer three times and topcoat four times on the substrate. Each time the paint is painted, it is sent to the dust-free temperature baking room for baking. B. Spray paint: Grind the tweed on the substrate, then spray paint on it, and dry it naturally.Paint film.

How to bake the full paint of the car?

Transparent paint is processed, then transparent paint, and then waxing begins. Just like cars, coarse wax is first waxed with fine wax, which is the piano baking paint. Drying treatment. Each time the substrate is painted, it is sent to the dust-free constant temperature baking room for drying treatment, and so on. Repeat three, four or more times.

Painting. After filtering out the impurities, the raw paint is heated, stirred and dehydrated, which is the push-glush paint. Cashew paint is cashew shell oil with solvent and other chemical materials. After heating and chemicalizing in the reactor, it is a synthetic cashew paint. Paint it.

Cleaning, identification, evaluation and shielding After cleaning the whole car, identify the type of old coating, evaluate the degree of damage to the workpiece, and determine the repair process.Masking and deoiling Protect the area around the damaged part with masking paper, and de-oil the area that needs to be polished at the same time.

Spray several layers of paint on the base sanded to a certain degree of roughness (usually high-density plates). And it is shaped by high-temperature baking. At present, this process has high requirements for paint and good color rendering.

Cleaning: First, clean up the surface of the car comprehensively, remove dust and debris, and determine the maintenance process. Oiling: Oiling the area to be painted. Sanding: Choose the appropriate sandpaper to sand the part that needs to be painted, and be sure to grind all the paint flat.

After applying putty, the car can enter the baking room to spray colored paint. After baking, it needs to be sprayed with varnish, that is, glossy paint. The large parts that have been dismantled, such as the hood, bumper, etc., are also carrying out the above work simultaneously.Plastic mesh parts such as bumpers should be sprayed with plastic before painting.

What is the difference between automotive baking paint and ordinary spray paint

The difference between baking paint and spray paint are: different operation methods, different material selection, different construction skills, different safety, and different cost.

The classification is different. Baking paint is divided into two categories. One type of low-temperature baking paint has a curing temperature of 140°C-180°C, and the other category is called high-temperature baking paint, and its curing temperature is 280°C-400°C. High-temperature baking paint, the full name in English is Polytetrafluoroethylene, abbreviated as Teflon, PTFE, F4, etc.

Car baking paint and ordinary spray paintThe differences are: from the process, the baking paint is to apply primer three times and four times the surface paint on the substrate. Each time the paint is painted, it is sent to the dust-free temperature baking room for baking; and the spray paint grinds the tweed on the substrate, and then sprays the paint on it to dry naturally.

Different processes. Baking paint is to apply primer three times and topcoat four times on the substrate. Each time the paint is painted, it is sent to the dust-free temperature baking room for baking. Spray paint is to grind the tweed on the substrate, and then spray paint on it and dry it naturally. Different paint films. The corners of the baked paint are smooth and the color is the same. It proves that the paint film is uniform and the color is full.

How many degrees is the appropriate temperature of car baking paint

Generally speaking, the baking paint temperature of the original car paint is between 120℃ and 150℃. In this temperature rangeInside, the paint surface can achieve the ideal drying effect in a short time, so as to ensure the quality and appearance of the paint surface. Of course, the baking paint temperature may also be different for different car brands and models.

Between 130 degrees and 180 degrees, use a paint called cross-linked hardened paint. The car paint spray used when the vehicle leaves the factory is controlled by the computer, and the robotic arm is sprayed, which is very uniform and almost flawless.

Painting is the same in any season. Because most regular paint shops have professional baking shops, and the temperature of the baking room can also reach 50 or 60 degrees in winter, so painting is generally not affected by the season.
