Who said, is it necessary to spray chassis armor on cars?

It's necessary. As the saying goes, a bad car goes bad first. When people want to maintain cars, the chassis of cars seems to be a neglected part. This has led to many cars that look glamorous, and the chassis has long been rusty and full of loopholes. There are many reasons for chassis problems, such as the invasion of rain, moisture and salt in the atmosphere, which will erode the bottom of the vehicle and lead to premature aging of the vehicle.

The automobile chassis ensures the safety of the vehicle and the owner. Once rusted and corroded, the whole structure is often easy to loosen, which brings security risks. Many traffic accidents are caused by loose chassis. Therefore, before things happen, it is essential to make a chassis armor for the new car.

Automobile chassis armor spraying has the following functions:

1, anti-corrosion: the corrosion of the car starts from the bottom plate. Have you noticed that rust spots have begun to appear on the side beams of cars that have only been in operation for three or five years? The humid weather in the south, coupled with the fact that every car wash sewage will remain at the bottom, will form potential corrosion factors for a long time, causing damage to the car. After the maintenance of the underbody, even acid rain, snow melting agent and alkaline water for car washing can't erode through this protective film.

2. Stone prevention: pebbles will be splashed when the vehicle is driving, and the impact of pebbles on the floor is proportional to the speed. General10g pebbles will have an impact force of 30,000 times their own weight when the speed reaches 80km/h, which is equivalent to throwing stones at eggs! It is enough that the paint film below 30 microns breaks. Once the paint film is damaged and corroded, it starts from the defect and slowly expands from the inside of the iron plate. After your car bottom is well maintained, even if the gravel is hit with 300 kg of force, it will not be broken.

3. Shockproof: The engine and wheels are fixed on the floor of the car, and their vibration will rattle with the floor at a certain frequency, which makes people feel uncomfortable. The bottom protection will eliminate this oscillation.

Operation process of automobile chassis armor

1. Preparation:

1 Tools: car washing tools, elevators, air pumps, blow guns, towels, buckets, chassis armored spray guns.

Products: asphalt remover, 6 bottles of chassis armor, newspapers, textured paper and sandpaper.

Second, the operation process

1 Cleaning the vehicle: Before construction, thoroughly clean the parts under the vehicle to ensure dust-free and oil-free. If there is rust, it should be sanded clean. After cleaning the bottom of the car, use a towel with a gun to blow the water in the gap to ensure that no water drops fall.

2. Shielding: Cover the parts that can't be sprayed with newspapers and textured paper: exhaust pipe, engine, transmission shaft, three-way catalytic converter, galvanized plate radiator (generally above the exhaust pipe), various pipes, interfaces and screws; Cover the tires, brake discs and car body with newspaper to ensure that it will not spray on the car body when painting.

Some automobile wheels are protected by a whole piece of PVC board, so it is necessary to remove the wheels, then remove the PVC board and spray the exposed metal parts inside.

Spraying: The construction site is the vehicle chassis steel plate, wheel arc, fender and fuel tank shell, and the construction personnel wear masks. Before each use, shake the container evenly (pay special attention), open the pull ring, put the straw of the spray gun through the aluminum film, tighten the interface between the container and the spray gun, and start spraying.

Note: Immediately after construction, clean the chassis glue that was accidentally stuck to the car body and other places. Please remove it with asphalt remover. Tear off the newspaper for the cover. Tape and clean up the site.
