Cars rust7Coup Effectively prevent the oxidation of the car rusting

Skills1:Alert to fine point small scars  Often appear car paint surface rust,In addition to the common collision、The scratch,Driving a tyre pop-up small stones in the paint,Also can cause a small peeling paint,Time is long can produce rusty spot。But most of these small scars because in the small place,Easy to miss。So,At ordinary times to regularly check body,Engine hatch and around the body,Once found will be timely to professional salon for processing。


The principle of rustproof packaging technology

According to the different corrosion medium,Can be divided into atmospheric corrosion、Sea water corrosion、Corrosion of underground、Bacteria corrosion, etc。Encountered in packaging engineering is one of the most atmospheric corrosion。Corrosion for metal materials and products have serious damage。According to the test,If steel corrosion1%,Its strength will reduce5%~10%,Thin plate is more easily lost use value due to corrosion perforation。Metal products for the loss caused by corrosion is far more than the value of material used。


What is the cause of corrosion?

Hong da anti-rust paper today to tell you about:Is there are many reasons for metal rust corrosion,One of the main reason is that may be metal in storage、In the process of transport and use,Due to the environment and the water vapor in the air、Oxygen、The effects of various ingredients such as acid and alkali salt and carbide。Metal at a certain temperature and humidity conditions,Physical and chemical changes will happen,So that the metal rust corrosion reactions。The corrosion of the metal will cause the metal structure change,Some metal parts will lose working ability because of the rust。That is to say,Metal contact with moist air or electrolyte solution to oxidize reaction occurs。
