The mobile trash bin integrates airtightness and storage. It combines cleanliness, beauty, safety, and environmental protection, reflects the new fashion and new concept of green life, improves the overall image of urban areas, communities and other places, thereby enhancing the protection of the living environment of the people consciousness.

The exterior of the box is sandblasted and electrostatic sprayed. The interior uses imported anti-corrosion primer for ships; the rear doors and side doors are equipped with automatic cylinder support; and equipped with pedals to open, the rear door fixtures use stainless steel fixtures; the side doors are equipped with side door locks; the rear door sealing strips are cylindrical EPDM rubber.

Because of its special metallographic arrangement and surface passivation film, it is generally difficult to chemically react with the medium and be corroded, but it is not impossible to be corroded under any conditions. In the presence of corrosive media and inducements (such as scratches, splashes, cutting slag, etc.), stainless steel can also be corroded by slow chemical and electrochemical reactions with corrosive media, and the corrosion rate is appropriately fast under certain conditions. Rust phenomenon. Therefore, we should take all useful measures during the processing of stainless steel trash cans to prevent the occurrence of rust conditions and inducements as much as possible. In fact, many rust conditions and inducements (such as scratches, splashes, cutting slag, etc.) also have obvious adverse effects on the appearance and quality of the product, and they should and need to be overcome.

1. Surface pollution: oil, dust, acid, alkali, salt, etc. adhering to the surface of the workpiece are transformed into corrosive media under certain conditions, and chemically reacts with certain components in the stainless steel parts, causing chemical corrosion and rust.

2. Surface scratches: Various scratches damage the passivation film, so that the appearance of stainless steel trash cans can be reduced, and it is easy to react with chemical media and cause chemical corrosion and rust.

3. Cleaning: After pickling and passivation, if the cleaning is not clean, the remaining liquid will remain, which will directly corrode the stainless steel parts (chemical corrosion).
