The following are common steps for cleaning tinplate cans:
1. Prepare materials
2. Soak and decontaminate
3. Gently scrub
4. Rinse clean
5. Dry and store
It is difficult to repair deep dents or can deformation caused by large impact or severe extrusion. In this case, the internal metal structure of the tinplate can has changed, and some materials may have cracks or interlayer separation, and external force alone cannot completely restore it to its original state.
Biscuits tend to soften due to moisture, and the material and structural design of tinplate cans can reduce moisture penetration to a certain extent. The tin coating not only prevents corrosion, but also blocks some moisture, slowing down the effect of moisture on the biscuits in the can.
Tinplate is a composite material with a layer of tin on the surface of low-carbon steel. It has the strength of steel and the corrosion resistance of tin, so it is widely used in packaging in the fields of food, chemicals, cosmetics, etc.
The anti-rust performance of tinplate depends first on the quality and thickness of its tin plating. During the production process, the thickness of the tin layer is generally controlled in the range of 1.5g/m² to 15g/m², depending on the purpose of the can and the acidity and alkalinity of the food.
