Quali sono le applicazioni del passivatore in acciaio zincato nella produzione automobilistica?
What are the applications of galvanized steel passivator in automobile manufacturing?
The application of galvanized steel passivator in automobile manufacturing mainly includes the following aspects:
1. ** Improve the corrosion resistance of the body ** : The choice of auto body sheet is crucial to corrosion resistance, usually using single-sided galvanized steel plate or double-sided galvanized steel plate to improve the corrosion resistance of the body.
2. ** Special parts of the anti-corrosion measures ** : the car floor and wheel cover and other parts are often affected by sediment, gravel and other impact corrosion, usually need to spray PVC car bottom paint and anti-stone impact paint.
3. ** Weld sealing ** : In order to improve the corrosion resistance of the body, all bonding, weld or joint parts should be coated with sealant after electrophoretic coating to avoid the immersion of water and other media and cause corrosion.
4. ** Inner cavity wax injection or foaming treatment ** : Due to the thin electrophoretic paint film in the inner cavity of the car, the corrosion resistance is poor, usually spraying wax or injecting wax (filling wax) treatment to improve the corrosion resistance of the vehicle.
5. ** Anti-corrosion measures in the storage and transportation process ** : In order to ensure that the automobile coating is intact and no rust phenomenon occurs during the storage and transportation process, it is generally used to spray protective wax, chassis anti-rust wax and other measures.
6. ** Single-side passivation process of electric galvanized automobile oil tank plate ** : single-side passivation process of electric galvanized automobile oil tank plate is an emerging process, and the single-side coating process needs to be realized through the unique coating roller input, simulation of
7. ** Automotive fuel tank plate quality improvement ** : By optimizing the electric galvanizing production plan, thoroughly cleaning the pipeline and knife beam of the oil applicator, avoiding the problem of uneven oil coating and improving the surface quality of single-side electroplating products.
These applications demonstrate the diverse uses of galvanized steel passivators in automotive manufacturing, from improving the corrosion resistance of body panels to anti-corrosion measures in special parts, to protection during storage and transportation, reflecting its important role in the automotive manufacturing industry.
