The antirust of deep groove ball bearings is usually divided into inter-process antirust and finished antirust. Inter-process antirust is the process antirust, usually in 3 to 30 days. Generally, water-based antirust agents can be used. The advantages of water-based rust inhibitors are simple operation and low cost. And after rust prevention, there is no need for oil removal and cleaning. Finished product antirust generally refers to the antirust of deep groove ball bearings before they are put into storage or assembled after delivery, usually in about 1 month-2 years.
The advantages of VCI antirust paper packaging are good antirust effect, no cleaning before assembly, easy operation, environmental protection and energy saving. vci antirust paper will always release a small amount of antirust agent (VCI definition: volatile rust inhibitor).
After packing with this paper, a gas protection layer will be formed inside the package, which can reliably inhibit the rusting of deep groove ball bearings. vci antirust paper has antirust effect both in direct contact with bearings and within a certain distance; VCI antirust paper packing antirust for bearings can prevent rust for up to 3 years; VCI antirust film packing antirust for bearings can prevent rust for up to 1 year. This most used is the product of HRB of Harbin, and now commonly used is the anti-rust process in plastic barrels.
