" In the process of storage and use, metal workpiece will inevitably encounter corrosion problems, especially in the summer when the humidity is high! Corrosion not only affects the appearance of the workpiece, but also may reduce its performance and service life. Today, with the help of the topics we are concerned about, we will reveal the causes of rust, and provide effective rust removal strategies to avoid hidden dangers of rust and ensure the appearance quality of the workpiece.

First, the cause of rust

1. Environmental factors: the climate humidity is high, especially in summer, the metal surface is easy to absorb moisture and accelerate the corrosion process.

2. Anti-rust agent, anti-rust oil quality: low quality anti-rust products can not effectively protect the workpiece, resulting in rust.

3. Cutting fluid pH: too high acidity will accelerate workpiece rust.

4. Improper cleaning: the polished workpiece is not cleaned in time after magnetic powder inspection, or the anti-rust agent and anti-rust oil are not used after cleaning.

5. Post-machining treatment: The use of cutting fluid is not cleaned and anti-rust treatment in time.

6. Insufficient transport protection: protection is not in place when trans-plant transport, and timely cleaning in rain and snow will also lead to rust.

7. Cleaning solvent problem: cleaning parts use acidic solvents before packaging, and the surface will rust quickly.

8. On-site storage before packaging: After grinding the fine parts, it is necessary to boring, turning and other processes, and no rust prevention is applied in the process, and rust will occur for a long time.

9. Storage after packaging: the workpiece after packaging is not picked up and shipped away in time, and long-term on-site storage is easy to lead to rust.

10. The surface of the workpiece is splashed with water: When cleaning the ground with a mop, the water and other acidic liquids splash onto the surface of the workpiece without paying attention to cleaning up will lead to rust.

Second, rust prevention measures

1. Cutting fluid management: Regularly use test paper to detect the pH value of the cutting fluid used, and reasonably control the pH value ≥9, when the pH value < At 9 o 'clock, cutting fluid should be added in time to prevent workpiece rust caused by high acidity of cutting fluid.

2. Post-processing: the processed workpiece should be cleaned in time, and anti-rust treatment should be done after the workpiece is dried.

3. Post-inspection treatment: Immediately after the completion of the inspection, use magnetic powder cleaning agent, and then rinse off with water, and do rust prevention treatment until completely dry.

4. Storage environment: Store the product in a dry and ventilated room. Do not place it outdoors or expose it to the air for a long time.

5. Clean and anti-splash: Avoid the water on the mop and rag splashing onto the workpiece.

6. Short-term storage: The customer has not picked up the goods, and the products that have not been shipped in the short term should be coated with anti-rust agent or anti-rust oil, and be packaged and stored.

7. Transport protection: In case of cross-plant transport, the workpiece needs to be coated with anti-rust agent or anti-rust oil to do a good job of anti-corrosion protection.

8. Anti-rust agent and cleaning solution management: sealed storage, be careful not to open storage, please seal the mouth of the barrel after each use.

9. Long-term storage treatment: for the workpiece stored for more than one year, reapply anti-rust agent or anti-rust oil according to the situation. If it is found that there is serious rust or parts with a tendency to rust, it is necessary to remove rust first, rinse it with water, and re-do anti-rust treatment after completely drying.

10. Delivery timeliness: The packaged workpiece should be shipped as soon as possible and delivered to the customer.

Third, rust removal methods

For the rusted workpiece, the rust remover of Kirui new material can be used to remove rust, remove polluting substances (carbon deposits) and remove oxides. The treated metal surface will not affect welding, electroplating and painting, and maintain the original color of the metal after rust removal, helping the workpiece to brighten, smooth and clean, and non-corrosive to the human body.

P.S. The above content is about rust prevention secrets, metal workpiece rust prevention and treatment related introduction, interested in rust prevention welcome to communicate with Kirui new materials, we will be happy to provide you with answers and application knowledge, here not only the value of anti-rust, rust removal products, but also experience intimate service.
