Attention car owners!
As the snow melts.
Relevant experts remind.
The car should be washed in time after snow.
Data map. In rainy and snowy weather, road traffic, urban management and sanitation departments will sprinkle snow melting agents to deal with the ice on the road. But what few people know is that traditional snow melting agents are corrosive.
Professor Jia Chuankun of the School of Energy and Power Engineering of Changsha University of Science and Technology introduced that the traditional chloride salt snow melting agent contains chloride, which is easy to corrode roads and bridges, and also easy to cause damage to roadside plants. Snow melting agents can also corrode car chassis. He explained that the metals used in automobile chassis are generally alloys, and under normal circumstances, they have a certain degree of corrosion resistance. However, exposure to salty snow water creates a "galvanic effect" that accelerates rust on the chassis of the car.
Professor Jia Chuankun's team is conducting a snow melting agent test.
In real life, is there a car that has been "corroded" by snow melting agents?
The reporter visited three auto repair shops, and the owners of the three repair shops all told the reporter that "no such problems have been encountered so far."
The owner of the first car repair shop, who has been in the business for eight years, said that although he had heard of the saying that "snow melting agents corrode car chassis", no customer had encountered such a problem so far.
The owner of the second repair shop, who has been in the car repair business for more than 20 years, also said he had never heard of a car chassis being corroded by snow melting agents. He was even surprised: "The chassis of a car is so easy to corrode, not to mention, we don't encounter such heavy snow days a few times a year." ”
Subsequently, the reporter visited two car washing shops. The owners of both car wash shops said that every year after rain and snow, more customers come to the shop to wash their cars.
The traces left by the snow melt on the car are obvious, especially in the black and blue cars. The owner of a cleaning shop said that the snow melt agent will leave white marks after splashing on the body, but it is easier to clean, and it can be washed with clean water.
