What causes the car chassis to rust? Most parts of the car know

In fact, there are two main reasons for the rust of the car chassis. The first reason is the types of plates used for the chassis of the car. The general car body materials are high-quality galvanized plates, which have good anti-rust properties. In other words, the use of high-quality plates for automobiles will basically not show rust. Some domestic brands used ordinary steel plates to make bodies in order to save costs. The results can be imagined. The body will appear rust in less than two years, even Some cars are rusty just a few months after they were bought.

The second cause of chassis rust is the spraying process. At present, there are mainly spraying processes such as electrophoretic primer, chassis anti-corrosion adhesive, paint surface, and varnish. The electrophoretic primer technology and chassis anti-corrosion adhesive technology are the best anti-corrosion performance.

It is actually an adhesive colloidal coating sprayed on the chassis of the car. It will solidify quickly after spraying to form a strong elastic protective layer, which can effectively prevent the impact of flying stones and gravel, and can also avoid wet weather. Corrosion of the metal of the vehicle chassis to prevent chassis rust and rust, and better protect the car.

Use a special chassis armor spray gun to spray the chassis armor products on the chassis evenly and dry naturally. It is best not to touch the water for the next two days after spraying.

The chassis of the new cars that have been manufactured are basically anti-rust. The more high-end cars are more particular, but for some more common cars, the original chassis protection measures will be weaker. Before the rust, the chassis armor is Very useful, can extend the life of the chassis.

During the driving of the car, it is inevitable that some splashed sand and stones will hit the chassis. When passing through uneven roads or deceleration ramps, it is easy to support the bottom. The chassis armor can resist the impact and avoid damage; When driving in a humid climate, the chassis is prone to accumulate water and corrosion, causing rust damage to the chassis. The chassis armor can cover the exposed metal to form a protective layer to isolate the contact with the outside; in addition, most of the noise of the car during the driving process comes from the chassis Inside the car, the chassis armor has a certain noise and noise reduction effect
