How to solve the problem of blackening of stainless steel electric heating tubes

What is the general treatment for a stainless steel electric heating tube that turns black? The steps are as follows:

1. The prerequisite for blackening treatment of stainless steel electric heating tubes is to keep the surface of the heating tube clean and tidy. If there are impurities on its surface, it will not be conducive to blackening treatment.

2. What needs to be done is to remove the organic matter on the surface of stainless steel electric heating tubes, which is called degreasing treatment. The requirement for degreasing treatment is to maintain an extremely high alkalinity of the liquid, with a stable pH value of around 13. The time requirement is approximately 30 minutes. After this treatment, the surface should be cleaned to remove impurities generated by chemical reactions. Cleaning must be done with clean water to ensure a high level of cleanliness on the surface of the heating tube.

3. After alkaline washing, it needs to be pickled. Because its surface not only contains alkaline organic matter, but also acidic organic matter. So acidic cleaning is also necessary. A pH value of 3 is required for acidity, and the processing time should not exceed about 10 minutes.

4. After completing the above three steps, it is necessary to ensure that the Ph is between 2-4. A time of 10 minutes is sufficient. After processing, proceed with cleaning.

5. Dry the stainless steel electric heating tube to remove the water adhering to the surface of the heating tube. Finally, apply oil.
