AutoBeta(AutoBeta.net)10/26 Report--

Recently, according to a video released by the Big Bang of understanding cars on the Great Wall Haver Dog and FAW Toyota RAV4, FAW Toyota released RAV4 when water came into the car during the governor test. after the frame was cut, the program found extensive corrosion on the inside of the B-pillar of the Toyota car. It is worth noting that according to the video, the vehicle is in the previous water intake, only at the bottom of the vehicle, and does not involve the B-pillar part of the vehicle.

In this regard, the program group of understanding Che Emperor explained that although it is possible that there is a high concentration of water vapor in the car after entering water during a long test, which will lead to rust in some parts that have not been treated against rust, but for vehicles, even water vapor with high solubility should not rust. After all, the frame has to be electrophoretic before spraying. As long as the electrophoresis process is done, it will not rust for a long time. It is obvious that there may be problems in the electrophoretic process of the disassembled Rongfang.

In response to this matter, some netizens said: now consumers are more and more difficult to deal with, generally here will not do too good anti-corrosion technology, there is little opportunity to soak in water to the a-pillar, Japanese car companies are very fine on cost control, most of them reduce costs here. Another netizen said: rust is not caused by soaking in water. In many southern areas, where the annual average humidity is more than 80%, it will be rusty if you don't soak in water. It's just like the brakes turn yellow as long as they don't open, especially in the rainy season; this is the lack of rust prevention, just like the rust wear of the chassis in Jianghuai more than a decade ago, all due to technological problems. In addition, some netizens said: if you let the bullets fly again, you may be filled with acidic liquid, the routine operation of the Japanese system, the Japanese car is not a myth, and other official responses.

According to the relevant data, automobile electrophoresis is a part of automobile painting, and the general automobile is equipped with three processes: primer, intermediate coating and topcoat. The purpose of electrophoretic process is to apply a layer of primer on the surface of metal products, which is different from other processes such as spraying, this primer is relatively simple in color, generally black or gray, but its anti-corrosion performance is better than other methods. it is generally used as primer coating for automotive parts, automotive vehicles, hardware and other metal products, suitable for mass production. At present, FAW Toyota officials have not responded to the matter. As to whether the FAW Toyota Rongfang exposed the problem of large area corrosion of the B-pillar is the problem of individual vehicles, or the same model has such a problem, this has yet to be answered officially, after all, vehicles can not be casually used to cut the frame.
