Handling method:
If carbon steel pipe fittings and seamless pipes have heavy oil stains, they should be degreased in advance.
2. Pour the pickling and passivation solution into a PVC tank or use a PP tank, or use an iron tank for temporary use. Soak the carbon steel pipe parts in the tank for 5-15 minutes.
3. Finally, clean it with tap water. It needs to be rinsed thoroughly.
4. Concentrate the wastewater treatment, neutralize it with alkaline lime water or sodium hydroxide, and discharge it when the pH value approaches 7. It has no impact on the environment.
Effect after processing:
1. The improvement of carbon steel corrosion resistance and rust prevention effect after treatment is influenced by many factors such as workpiece material, surface condition, climate, atmospheric pollution, dilution water quality, construction method, and workpiece stacking method.
2. The pickling and passivation solution does not contain harmful materials, and the wastewater can be directly discharged after neutralization treatment, without any impact on the environment.
Precautions for use:
1: The pickling and passivation liquid operation must be carried out outdoors or in a well ventilated room.
2: The operator should wear labor protection equipment before operation, and it is strictly prohibited for the skin to come into contact with acid pickling and passivation solution. If accidentally touched, immediately rinse with clean water.
3: The containers and tools used for acid pickling and passivation treatment should be plastic tanks that are resistant to acid corrosion.
4: The residue and wastewater from the acid pickling passivation solution after treatment should be promptly neutralized with lime milk or sodium hydroxide to prevent environmental pollution.
5: Do not operate in strong sunlight to prevent the stainless steel pickling and passivation solution from drying out and affecting the passivation effect.
