When it comes to buying a car, everyone’s most concern is nothing more than good looks, good power, low fuel consumption, good configuration, and few people pay attention to it.carThe anti-corrosion ability is OK but not OK! But do you know that if the car's corrosion ability is not good, it will affect the appearance of the car, and in the worst case, it will cause the occurrence of traffic accidents!
Why have I never published an article on such a serious problem, because I have relatively little understanding of automobile corrosion prevention, so this time I participated in the 2017 "Knowledge and Technology Open Course" of DENZA. The technical engineers of both China and Germany were on site. In-depth explanation of the problem of anti-corrosion of automobiles. Then, the useful knowledge cannot be enjoyed by me alone. I will sort it out today so that everyone can understand the cold knowledge of automobile corrosion prevention!
What is car anti-corrosion?
The picture shown above is a corrosion phenomenon often seen in daily life-iron rust. In fact, the corrosion of metal is not only the rust of iron. Corrosion refers to the deterioration and destruction of metal materials caused by chemical or electrochemical interaction with the surrounding medium in a natural environment or a specific environment. There are two concepts here-chemical action and electrochemical action.
The chemical action is the example just mentioned, the rust of iron-oxidation; the electrochemical action is achieved through the discharge of static electricity from the battery, which is the electrochemical action. Just remember one sentence simply, corrosion is equal to the deterioration and destruction of metals.
What factors affect the process of corrosion or the rate of corrosion?
However, the proportion of Dengshi body galvanized sheet is as high as 89%, spot weldingSealantThe amount of use reached 112.4 meters in length, and the length of the whole vehicle involving seam glue reached 125.6.In addition, in order to protect the weakness of the electrophoretic paint, a layer is added every time you buy a new car.Chassis armor, It is to prevent the stone from hitting the glue; in order to get the outside protection of all the cavities under the floor, wax injection is used to prevent the risk of corrosion.
In addition to the above, there are some unexpected corrosions in the car.
1. The lifting point of the body is when everyone is going to do maintenance, the car will be lifted. There are four contact points with the car, and the four contact points are the lifting points.
The lifting point of many cars is generally in contact with the body, and it will also have a certain amount of friction. When the number of frictions is high, the paint will fall off. This place is prone to corrosion, the corrosion will expand, and it will be dangerous. Therefore, a plastic part is specially set for the lifting point in this place, and there will be this plastic part every time the lifting point, so as to play a protective role.
2. The threshold area is the part underneath every time the door is opened. In order to avoid the risk of metal parts being hit by stones, DENZA has designed an additional plastic part so that it will not be corroded.
3. Tenshi's welding parts have additional coating protection, why? If our body is broken, it is equivalent to scrap. If other parts used on our body are also installed on the body, if the things on the body are broken, it is equivalent to the car is broken. So in order to avoid this kind of risk, take the initiative. All the welding fasteners on the car body, before welding, are just like the plate shown just now. These are extra protection to ensure that the parts of our car will not be replaced due to the use of the car.
4. All the craft holes outside the car body are locating openings when we weld during the production process, and locating openings are generated when assembling. After the production of the car is off the assembly line, these holes are no longer needed. All the process ports outside of our car are sealed with caps. The caps have two functions: the first function is that the cut edges mentioned just now are easily corroded. The outer seal of our car must give all the holes Block it up to ensure that water does not flow into the cavity, which is our hindrance.
These are a few measures for Tengshi's anti-corrosion ability to do better.
Summarize:Car anti-corrosion design can largely avoid the occurrence of traffic accidents caused by mechanical performance degradation, part failure, vehicle failure, etc. Therefore, if you are a friend who has bought a car, you should do your daily car anti-corrosion work and do not leave the car for a long time. Do not open, start the vehicle regularly. If the car is not used for a long time, the car should be cleaned regularly to avoid dust cover and prevent the car from corroding.
And if you are planning to buy a car, you should also take the factor of car corrosion into consideration when buying a car. Tengshi is a good choice!
