How to clean the oil produced by stainless steel processing?

How to clean the oil produced by stainless steel processing?

Among the metal materials used in industrial production, stainless steel is one of the most used. Stainless steel to achieve the use of standards, need to be forged processing, and in this process will make stainless steel surface contaminated with a variety of dirt, which is mainly oil. For the requirement of processing and protecting stainless steel, the dirt removal is very necessary. Stainless steel cleaning agent is used in stainless steel decontamination process of a cleaning product.

How to withdraw electroless nickel plating?

How to withdraw electroless nickel plating?

Electroless plating is also known as electroless plating, because although there is electron transfer in the process of workpiece plating, there is no need to connect the external power supply, the workpiece surface coating is completely achieved by chemical REDOX reaction. The removal of electroless nickel coating is much more difficult than that of electroplating, especially for high corrosion resistance electroless nickel coating. Unqualified electroless nickel plating layer should be removed before heat treatment, otherwise the plating clock backward plating is more difficult, requires that the plating solution must have no corrosion on the substrate, followed by plating thickness, plating speed, plating cost and other factors should be considered.

Mobile phone plate stamping oil how to clean?

Mobile phone plate stamping oil how to clean?

At present, there are two main materials for mobile phone medium plate: aluminum magnesium alloy medium plate and stainless steel medium plate. Processing technology is generally used by stamping technology. Because the stamping process in order to ensure the quality of the metal surface and prolong the service life of abrasive tools, stamping oil needs to be used to lubritate and cool the stamping process. At present, the stamping oil used on the market is mostly used to mineral oil, synthetic resin and some polymer lubricants and other raw materials. These substances are easy to form oil film on the metal surface, causing greater difficulty to the rear cleaning.

How to clean the zinc coating on the metal surface?

How to clean the zinc coating on the metal surface?

Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play a beautiful and rust-proof role. The most common method to remove zinc coating is to use hydrochloric acid pickling to remove zinc, which dissolves rapidly in hydrochloric acid. In order to save costs, in electroplating plants, iron and steel are used for rust removal and the remaining waste acid is used for zinc removal. It usually takes only tens of seconds to remove the zinc plating layer with hydrochloric acid, except for hot-dip galvanizing or zinc spraying. Because the two zinc layers are thicker, the time for zinc removal is slightly longer. Due to the influence of the current environment, it is no longer suitable to use this province for cleaning. At present, the more suitable cleaning method is water-based stripping solution, which can easily remove the zinc coating on the metal surface, and soak it at 80 ℃ for about 15 minutes, without harming the metal, and truly achieve environmental protection and pollution-free green cleaning.
