Reaction Vessel: Acid Pickling and Passivation of the Reaction Vessel

Hydrogenation Reaction vessel It is used in many industrial processes, including vulcanization, nitration, esterification, alkylation, polymerization, condensation, and other processing operations. It will be pickled and passivated. To prevent corrosion, let me now introduce hydrogenation. Reaction vessel Pickling and passivation treatment measures:

1. There are many corrosion-resistant materials suitable for pickling. Among them, epoxy resin adhesives and modified epoxy resins are the best.

2. The principle of stainless steel pickling is to use an acidic liquid after pretreatment to remove the oxide scale from the steel surface and eliminate surface metal ions, thereby achieving a high degree of smoothness and finish.

3. Therefore, the selection of anti-corrosion materials directly affects the normal operation of mechanical equipment, workshop floors, pipeline trenches, as well as the environmentally friendly recovery systems for wastewater and exhaust gases.

4. The forms of materials subjected to acid pickling include strip pickling, tube pickling, plate pickling, wire pickling, and more. Regardless of which pickling technology is employed, the stainless steel acid pickling production line—from the moment the material enters the process until it is discharged into the wastewater system—experiences intense corrosion at every stage, including in the exhaust gas recovery system.

5. Corrosion protection for ground-level and production-line machinery and equipment. Nowadays, the primary raw material—epoxy resin—for most fiberglass reinforced plastics (FRPs) made from fiberglass corrosion-resistant materials directly determines the effectiveness of corrosion protection. Therefore, the quality of the selected epoxy resin directly affects the service life of the corrosion protection.

6. The pickling solutions used in the stainless steel pickling process typically consist of a mixture of various acidic compounds, primarily hydrochloric acid and nitric acid. These mixed acids are highly corrosive and possess strong oxidizing properties; moreover, the temperature of the etching medium is also relatively high. Clearly, these factors set stringent requirements for the corrosion resistance of anti-corrosion materials.

Hydrogenate this. Reaction vessel It features rapid heating, heat resistance, corrosion resistance, hygiene, automatic heating without the need for a heating furnace, and ease of use. We must understand the pickling and passivation treatment of mechanical equipment to maintain its original condition. Improve production efficiency and extend service life.
