Many people wash their cars in the scorching sun, so is it good for the car paint

Bad damage to the car paint car washing under the scorching sun will cause some damage to the car paint, so the convex lens effect formed by water droplets under the scorching sun will cause the top layer of the car paint to produce local high temperature, which will cause the car paint to lose its luster for a long time. Here we also want to emphasize that the vehicle should not be washed after a long period of exposure to the sun, and the sudden cooling and convex lens effect will also cause damage to the car paint. Brother Persimmon replied like this.

Not good... First, the water droplets become a concave lens effect, and the refraction of light increases the concentrating temperature of the paint, which is very damaging to the paint. Second, under the scorching sun is high temperature, suddenly the car wash is low temperature, one hot and one cold in one hot, so that the paint can withstand the test of thermal expansion and contraction, and also let some interior plastic parts be damaged...

3. Under the scorching sun, it can't be cleaned. Water stains are present on the painted surface.

Of course, the temperature on the surface of the car will be very high after exposure to the scorching sun, it is best to ventilate in a cool place for a period of time, and then wash the car when the temperature drops, which will play a certain role in protecting the car paint.

After the exposure to the sun, the car wash on the car's paint is definitely not good, thermal expansion and contraction will make the paint aging and cracking, as for the convex lens will increase the temperature is pure nonsense, because there are water droplets to cool down how to increase the temperature, at least physical knowledge is not understood, use a paper cup to fill a glass of water, the following with fire, the water is boiled, the paper cup will not be broken, understand.

Definitely not, it is recommended to wash the car, it is best to wash it in the morning or evening, when the sun is not strong.

This is not good for the car paint, the weather hot water evaporates quickly, and it is easy to hurt the car when wiping the car.

There shouldn't be anything wrong with that.

The summer sun is very damaging to the skin, and it is no less damaging to the car. For example, milky white car paint will have a more obvious yellowing condition after a long period of exposure, and at the same time, it will also make the car paint dull. For example, in the southern region, in addition to the exposure to the sun, there are also heavy rainstorms in summer, not to mention whether the car will be soaked, and the accumulation of acid and alkaline rain will also have a corrosive effect on the car paint.

In addition to the paint, summer exposure to the rubber position of the vehicle will also bring harm, such as panoramic sunroof, door window glass and other parts are rubber strips to maintain the vehicle, long-term exposure will accelerate the aging of rubber, the occurrence of aging hard bottoming, <>

Not only does this rubber lose its buffering and sealing properties, but it can also cause rainwater to seep into the car. After the vehicle is exposed to the sun, whether there is a smell of plastic when it is opened, there are many decorations on the instrument panel that are all plastic, and the sun will speed up their old position, and the door window glass panoramic sunroof has rubber strips, and long-term exposure to the sun will also crack and age, endangering the airtightness, and there will be rainwater seeping in on rainy days. There are also plastic products that will release indoor formaldehyde through exposure to the sun, which will affect people's health when they stay in the room.

Car paint is generally divided into four layers: electrophoretic layer, topcoat layer, varnish layer, and topcoat layer. There is a difference between the original paint and the spray paint after the injury.

The paint that is sprayed after is basically only clear coat and top coat. The original car paint is all high-temperature paint of nearly 200°, and the topcoat layer can effectively prevent direct UV rays, and the high ambient temperature in summer is basically not a problem. The paint sprayed after is tempered at 60° in the car paint room, but the topcoat used in the general car paint room is relatively cheap, and the resistance to ultraviolet rays is much worse.

Exposure to the sun for a long time will not only damage the car paint, but also have a great harm to the car interior and its dashboard.

First of all, the temperature in the car rises rapidly after sun exposure, and the ambient temperature of the seat can reach sixty or seventy degrees; Secondly, because of the exposure to the sun, many harmful substances will be produced in the car, which endangers the health of the staff in the car; Moreover, it is easy to cause premature aging of the car interior and instrument panel. After getting into the car, the panoramic sunroof and window glass will be used to start the car (no need to blow the air conditioner at this time), so that the temperature in the car can quickly drop to a balance with the external environment according to the flow of air during driving, and the learning process must only take one or two minutes. Then turn on the air conditioner so that the vents are blowing upwards, and change the air conditioning cycle to the in-car cycle.

Generally, exposure to the sun after washing the car will not cause damage to the car paint, but it should be noted that the car cannot be used with cold water at a low temperature at noon, which may cause the car paint to crack or even damage the metal structure in the car.

Yes. Because the car is often washed in summer and exposed to the sun, the car paint will be aged, so the car paint will be damaged.

In summer, the car is often washed, and the sun is often exposed to the sun, which has no effect on the car paint. Just don't wash your car with sea salt water when you wash it.

Exposure to the scorching sun has an impact on the paint. Long-term exposure to the summer sun will cause the paint to lose its original luster, making the paint surface dull and dull, and there will be problems such as fading and aging. Here's an introduction to car paints:

1. Definition: Paint is a chemical mixture coating material that can be firmly covered on the surface of objects for protection, decoration, signs and other special purposes. The authoritative book "Coating Technology" in China's paint industry is defined as follows:

Coating is a kind of material, which can be coated on the surface of the object with different construction processes, forming a solid film with strong adhesion, a certain strength, and a continuous solid film. The film formed in this way is commonly known as the coating film, also known as the paint film or coating. \"2. Ingredients:

Coatings are generally composed of four parts: film-forming substances, fillers (pigments), solvents, and additives. According to the performance requirements, sometimes the composition will change slightly, such as the varnish does not have pigments and fillers, and the powder coating can be made without solvents. "

The effect of a car wash on car paint in winter.

1.Wash your car with hot water after snow.

Some car owners use hot water when washing their cars after the snow, car maintenance experts remind that taking a hot shower after the snow is the destruction of the car, because the sudden change in temperature will damage the car paint, so that it gradually loses its luster, and the windshield of the car may also burst in the pouring hot water. After snow, the car can not be washed directly with cold water, especially after the engine heats up, the temperature of the front of the car is high, and washing with cold water will cause rapid cooling, which is very unfavorable to the surface paint, and can not directly flush the engine. At this time, the correct way to wash the car is to start the car and turn on the heating system on the car, and then wipe the car with warm water.

After washing, the door should be opened to wipe off the water traces to prevent the residual water from freezing in the door cracks. Do not force the windows to open and close if they are frozen, especially the power windows.

2.Car washing after snow is not timely.

Sometimes it snows for a few days, and some car owners put off the car wash again and again, and when they wash the car, they find that the car paint is still not as shiny as before. Car beauty maintenance experts say that car washing after snow should be timely, even if the weather forecast shows that it will snow in the next few days, do not drag the car without washing. As soon as it is covered with snow, wash it off with clean water immediately.

Snow contains corrosive components, whether it is paint, chassis, tires, or wheels, and long-term snow cover can cause injuries.

3.Wash your own car without changing the water.

Most car owners know that washing their car immediately after snow will protect their car. But there are also people who wash their car paint and get worse the better. Because these car owners often carry a bucket of water and a rag to wash the car.

It's not impossible to wash your own car, but many people don't do it right, and some car owners only use a bucket of water when washing their own cars, and the mud and sand repeatedly entrained in the bucket scratch the car paint. In addition, it is impossible to wash away the salt and alkaline substances in the snow water with clean water alone. Car maintenance experts suggest that it is best to go to a professional car wash and rinse the body with a large amount of running water and neutral detergents added to the water, and the wheel brushes that are specially designed to clean the wheels will clean the sludge in the cracks of the wheels.

4.The chassis is clean and not rust-proof.

Some car owners reported that they went to a professional car wash to wash their cars immediately after the snow, but they don't know why the chassis of the car was corroded. Car maintenance experts explain that car washing machines are equipped with chassis flushing equipment, and a powerful water column is sprayed upwards to flush the chassis, which can completely flush the muddy water attached to the surface of the chassis, but a large amount of water will also be sprayed to all parts of the chassis during cleaning. In this way, the metal parts of the chassis quickly appear to rust.

Rust accelerates chassis damage and is not easily remedy. Therefore, after thoroughly rinsing the chassis with a car washing machine, it should be dried immediately, and then the anti-rust treatment should be carried out by professionals with a special car chassis rust inhibitor. Rust inhibitors contain anticorrosive agents, wet removers and synthetic penetrant protectants, which have a special effect on resisting salt spray and humid air. Hope.

Hello, you can wash the car and wrap it in winter, but it can't get wet after the film, and you can't lift the glass of the car, these two points need to be paid attention to, I hope I can help you, thank you.

If you have the conditions, wash them with warm water, if it's cold, you wash the car with cold water, the water droplets on the car will freeze the paint on the car, and the car lock is empty.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Hello, of course you can, no problem.

Toxic gases will live forever in the car.

Exposure to indoor leather will produce formaldehyde, which is harmful to people, and it will crack after a long time in the place where there was putty after the surface paint is exposed. It is recommended to park with the front of the car facing away from the sun when parking, buy a reflective curtain and put it on the windshield or rear windshield when you get out of the car, which is easy to sunburn the paint in the car and the front and rear bumpers, which is of great benefit!

Attach the place to pay attention to when washing the car.

Precautions 1: Use cold water with caution when washing cars in summer.

Many car owners like to wash their cars in cold water to cool their cars, which leads to problems with the interior machinery and paintwork. In the process of high-speed driving, the engine, chassis and other operating systems are in a high temperature state, in this case, washing the car with cold water, the temperature difference is huge, which will cause damage to the metal structure of the car, especially the internal structure of the machinery, and may even burst. The body is exposed to high temperature for a long time, and the temperature is extremely high, and the car with cold water is very easy to cause the aging of the car paint.

Note 2: "Forced car washing" essentials.

After experiencing moderate to heavy rain, heavy snow or long distances, the vehicle must be washed thoroughly, if it encounters continuous precipitation, it is not necessary to wash it every day, but in the rainy process for a short sunny day, you must go to clean the vehicle, some car owners will say that this is a superfluous move, because after washing and encountering rainfall, washing the car is equal to a waste of effort, in fact, it is not, because the long-term rainfall does not wash the car is easy to lead to more dirt under the car chassis, and the accumulation will cause harm to the car.

Note 3: How to wash the car by yourself.

It is convenient to wash the car by yourself and save money, but you can't wash the car because of these two small cheapnesses. First of all, you should prepare a sponge, a bucket, a little car washing liquid, a piece of suede and other car washing tools; Secondly, the principle of top-down should be followed when washing the car, at least two buckets of water should be used, and some places that touch the internal power line should be wiped with a damp cloth as much as possible to avoid damage to the interior of the car; Finally, after washing the car, it is best to spray a circle of tire protector (foam-like) on the tires.

Note 4: Don't take the computer car wash lightly.

The quickness of brain washing is loved by car owners, but there are also drawbacks. Car washes are divided into two types of roller brushes, plastic and cotton, plastic brushes are used to "pump the car", usually with huge friction and easy to cause wear on the surface of the car paint. After a long time, it is easy to find whip marks on the body.

As a result, the body loses its luster, so it is safer to choose a cotton roller brush with more flexibility. In addition, the car wash liquid in the general car wash shop will use chemical solution, which will cause oxidation of the surface of the body and lose its luster.

Wash your car frequently in the summer, and exposure to the sun is less likely to damage the paintwork. Because there are two components of car paint, one is acrylic as the main ingredient, and the other is polyurethane as the main ingredient. Acrylic is afraid of the sun and will fade under ultraviolet rays, and polyurethane has nothing to do with it.

The original paint is basically polyurethane. However, if you have done paint on the outside, it is likely to be acrylic. Because repair shops want to reduce costs, and acrylic is cheaper.

It should be noted that if you are afraid that exposure to the sun will damage the car paint, you should not dry it often. Also, pay attention to the stickers on the paint, after a long time to tear off, the color of that area will be darker than the rest of the place.

The fundamental solution to the protection of car paint and car glass is to cover, through the medium to make air or sunlight and paint and glass less contact, there are two ways to see at present: the first is the car coat, the protection of the car is more comprehensive, but it is relatively difficult to retract, if the material is not good in the wind and rain, there is damage to the paint surface; The second is the paint glaze or coating, glass film, which is very good protection for the car, the cost is relatively high, but the car is always protected. It should be reminded that no matter what kind of protection there is gum, bird droppings, insect carcasses and water on the paint surface, it must be cleaned up as soon as possible, otherwise any kind of protection will have no practical effect.
