According to the GNEE STEEL galvanized sheet manufacturer, if the galvanized sheet is stored in a humid environment for a long time, a layer of white rust will easily form on its surface. This is essentially a loss of the zinc layer, and the corrosion resistance of the galvanized sheet will also be affected. So how to prevent the occurrence of white rust? Below, the GNEE galvanized sheet manufacturer with better service will explain in detail the measures to prevent the occurrence of "white rust".
1.Chemical passivation
GNEE galvanized sheet manufacturer introduces that in order to minimize the chance of white rust forming on galvanized sheets during storage and transportation, manufacturers usually perform chemical passivation treatment on galvanized sheets during the production process. Chemical passivation is usually performed on a hot-dip galvanizing production line. It mainly adds an invisible film on the surface of the zinc plate. This film will not affect the performance of the galvanized plate.
2. Apply anti-rust oil
GNEE galvanized sheet manufacturer explains that effective measures to prevent white rust on galvanized sheets also include applying anti-rust oil on the surface. Anti-rust oil is an oil containing special chemicals such as corrosion inhibitors. It is applied by GNEE galvanized sheet manufacturers on the production line with the help of an electrostatic oiling machine. If the customer needs to perform subsequent painting operations on the galvanized plate, then applying anti-rust oil is a better choice.
3. Proper packaging and storage
GNEE galvanized sheet manufacturer introduced that if galvanized sheets are properly packaged and stored, the possibility of white rust on the surface will be greatly reduced. GNEE galvanized sheet manufacturer, which is highly praised by everyone, introduced that it is a correct preservation method to properly wrap the galvanized sheet with some complete packaging materials containing corrosion inhibitors and store it in a dry environment. GNEE galvanized sheet manufacturers remind users not to store galvanized sheets for a long time as much as possible.
In summary, GNEE galvanized sheet manufacturers explain that effective measures to prevent "white rust" from galvanized sheets include chemical passivation of the surface, application of anti-rust oil, or proper packaging and storage. In addition, the GNEE galvanized sheet manufacturer clarified that the quality of the galvanized sheet material itself also affects whether it is easy to produce "white rust". Customers should still choose galvanized sheets that meet the quality standards.
