carCorrosion is a relatively common situation for car riders in the south. Corroded cars may damage the exterior covering parts, and may reduce the strength, comfort and safety factor of the structural parts.
In this issue, we will talk about corruption.
1. What happens after the car is corroded?
Let’s take a car that is closely related to our lives. We can often see many scrapped or abandoned vehicles in our lives. If these vehicles are parked in a certain place for 1 year, 2 years or longer, we will find rust on the body. Spotty.
This is the phenomenon of corrosion, because most parts of the car itself are iron or contain iron components.
Let's take a look at a set of photos:
From the picture above, we can intuitively see how severe the car body is after being corroded. Of course, the picture above is an old model, the previous technology is not as developed as it is now, and there is not too much investment in anti-corrosion design.
After talking about the severity of car corrosion, let's talk about what caused it. One is the design, and the other is the later use of the car owner.
2. Can the anti-corrosion design cut corners?
At present, the anti-corrosion design of the car body is relatively strict in the market, and the process is relatively cumbersome, which increases the cost. At this time, some unscrupulous manufacturers began to make their own calculations. Next, Che Jujun will explain the main processes to everyone.
▎Electrophoresis coating: Nowadays, an anti-corrosion technology widely used in automobiles. Simply put, after the anode and cathode in the colloidal solution are connected to the power, the body in white is put into the cylinder, and the product of the combination of the anode and the cathode is adsorbed on The top of the car body is also commonly known as lacquering.
Soaking for a long enough time can help the body-in-white to achieve full electrophoresis, and the electrophoretic surface will be more uniform, which is more conducive to the spraying effect of the middle coating and topcoat in the later stage.
However, it should be noted that it is not that the longer the soaking time, the better. If the time is too long, the excessive aging of the surface of the car body may cause the adhesion of the paint in the subsequent process to decrease. However, considering that this kind of anti-corrosion process is difficult to adhere to the car body at right angles, it is most reasonable to increase the soaking time within a reasonable range.
▎Seam rubber: Used in the car body gap, it has corrosion resistance, noise reduction and heat insulation performance and stone impact resistance. In addition, the cost of coating the seam glue is relatively high. The more places covered, the longer the production time and the increase in cost.
It is very necessary to go to a regular 4S shop for inspection and maintenance. If conditions permit, the car can be waxed regularly, which can play a certain anti-corrosion effect.
▎Compared with other cars, what is special about the anti-corrosion design made by DENZA?
This is about materials, such as double-sided galvanized sheets,Sealant, The amount of seam glue used is more than that of ordinary manufacturers. The use ratio of double-sided galvanized sheet reached 89%, the use of spot welding sealant reached 112.4 meters in length, and the length of the whole vehicle involving seam glue reached 125.6 meters. The anti-corrosion effect will naturally become stronger.
In addition, it is a bright spot in the wax injection process. Although this technology is not a black technology, in manufacturing, car companies usually want to reduce processing steps, because this will increase manufacturing time, and car companies usually have very strict control over manufacturing time. It is no exaggeration to say that time is money.
▎If my car is scratched, how can I judge whether I should go to the 4S shop immediately or wait until the next maintenance? Under what damage the vehicle, we must deal with it immediately to avoid corrosion?
If you do not have professional knowledge, you can call to consult relevant professionals, and you can go to a regular 4S shop for testing.
To give a simple example, for example, if the car door is scratched, if the primer is damaged and it happens to be rainy, if there is no important thing at this time, it is recommended to go directly to repair, otherwise the scratched part of the car door will be washed by rain. Days may cause corrosion.
Of course, you can also buy some by yourselfCar wax, I usually carry out some simple daily maintenance at home.
Car gathering summary
Automobile anti-corrosion design is a very important thing. When automobile metal parts are corroded, it may cause mechanical performance degradation, parts failure, vehicle failure, etc., which may lead to traffic accidents. Therefore, we must do a good job in anti-corrosion work, slow down the corrosion rate of metal parts, ensure the function of metal parts, and ensure the safety of drivers and passengers.
In addition, the requirements for car body anti-corrosion design in coastal areas are even higher, because the composition of the air in coastal areas is different from that in inland areas. In the coastal areas, the salt in the air, acid rain formed by industrial pollution and other harmful chemicals will definitely aggravate the corrosion of cars, and the high relative humidity in coastal areas will also accelerate car corrosion. Therefore, anti-corrosion design is a very necessary process.
Finally, Che Jujun wants to remind everyone that you must not leave the car for a long time. You must start the vehicle regularly. If it is necessary to park in the garage, open the garage door regularly, maintain ventilation and reduce humidity, and clean the vehicle in time to avoid a large number of Dust cover to prevent car corrosion.
