1. Pickling method and time: The pickling method should be carried out by a combination of static soaking and dynamic circulation. The pickling time is static soaking for 2 hours first, and then dynamic circulation for 3-4 hours. During the pickling process, samples should be taken frequently to test the pickling concentration. When the difference between the two adjacent test concentrations is less than 0.2%, the pickling reaction can be considered to be over.

2. Passivation treatment: After pickling, most of the scale and metal oxides on the surface of the liquid to liquid heat exchanger are dissolved and fallen off, exposing new metal, which is very easy to corrode. Therefore, after pickling, the stainless steel liquid to liquid to The liquid heat exchanger plate is passivated.

3. Pickling temperature: Raising the pickling temperature is conducive to improving the descaling effect. If the temperature is too high, the corrosion of the plate heat exchanger by the pickling solution will be aggravated. Through repeated tests, it is found that the pickling temperature should be controlled at 60cC. .

4. Concentration of pickling solution: According to repeated tests, the pickling solution should be prepared according to the concentration of formic acid 81.0%, water 17.0%a, buffer 1.2%, surfactant 0.8%, and the cleaning effect is excellent.
