Use of rust remover in Shanghai sheet metal processing

1 The operation of the sheet metal processing (chǔ lǐ) will be accompanied by a passivation film with a thickness of about 1 μm. It is a reaction product of special inorganic materials and steel in the rust remover, which can serve to maintain the steel. effect. The application of sheet metal processing in Shanghai has become more and more extensive, and the planning of sheet metal parts has become an important part of the product development process. It is necessary for mechanical engineers to master the planning skills of sheet metal parts and make the planning of sheet metal. Satisfying the requirements of the product's function and appearance, it can make the stamping die simple and low cost.

2 The processed (chǔ lǐ) workpieces should be separated and stacked to facilitate drying. The Shanghai sheet metal processing material will be sent to the CNC punch/cutting machine for punching/cutting. In the bending process, the primary consideration is tool selection, bending sequence, bending compensation, and bending interference. According to the sheet metal cabinet product, the welding, grinding, painting, assembling, packaging and other processes are carried out. After rust removal, please dry or dry the workpiece naturally. Do not wash with water. Spray or apply anti-rust oil as soon as the job is dry. If you want to achieve the best effect, depending on the working conditions, you can use a series of (oil-soluble, water-soluble, hard-film, dehydrated) high-quality rust inhibitors.

3 After using the rust remover for a period of time, the surface foam and sediment should be cleaned in time and analyzed for concentration (Analyse), so as to make up for the new rust remover and ensure the rust removal effect (see the concentration control method for details). ).

4 short-term exposure to this product (Product) is harmless to the skin, if long-term contact should adopt appropriate labor maintenance measures (wear glasses, rubber gloves, wear protective clothing, rubber shoes) to ensure sheet metal processing operation control Staff safety. Shanghai Jinjin processing technology, Shanghai Jinjin has not had a relatively complete definition so far. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compositing, folding, riveting, splicing, Forming (such as car body). If you accidentally spill liquid into your eyes, rinse immediately with water or seek medical advice. Do not swallow the rust remover.
