In order to reduce the sliding friction between the CNC blade and the material, emulsified oil is used in the production process of the aluminum coil, so many products will leave some oil stains on the surface after processing, and these oil stains cannot be wiped off with a rag.
There is a coating on the surface of the aluminum coil, and the coating plays an important role in "anti-corrosion". Let's talk about how the anti-corrosion work of aluminum coils is done? Brushing: Brushing can use a variety of coatings, as long as it is not a coating with poor leveling.
The main reasons for the color difference after annealing of aluminum coils are: First there is oil; The second annealing time is too long How to reduce quality problems during annealing and continue to disturb most production and processing manufacturers.
Consumed aluminum coilsare generally placed horizontally during storage and transportation, and the consumption efficiency of an aluminum coil storage rack is in the original aluminum processing industry.
