Where do all the oils in plated steel parts come from? There are 5 sources, and in this article we will start with one of them, which is the corrosion protection of the base material. And how to choose the right steel degreasing powder.
For metal materials susceptible to atmospheric corrosion, in order to enhance their corrosion resistance during storage, they are coated with antirust grease at the factory. Typical examples are cold-rolled thin steel sheets (plates or coils of steel strip), which are coated with rust-resistant grease and plastered with rust-resistant paper or even plastic film.
Thin plate is usually used for stamping, bending and molding, once the starting point or piece rust, and can not be removed by mechanical grinding and polishing, it may be due to the lack of brightness, the surface of the flower and scrap. Therefore, cold rolled steel plate is often more oil and less rust, thorough degreasing has become the main pre-plating treatment process, but how to choose the steel degreasing powder has become a problem.
We have found in practice, different steel manufacturers coated with rust preventive grease is not the same, made of small pieces and difficult to electrolytic degreasing; and chemical degreasing, for a certain type of rust preventive grease removal effect of good formulations, the removal of another type of rust preventive grease effect may not be ideal. If the material is stored for a long time, it is more difficult to remove the antirust oil after it dries and solidifies.
