PFA Coated Industrial Reaction Mixing Vessel

Zhuoyan PFA Coated Industrial Reaction Mixing Vessel is a reaction equipment with a PFA anti-corrosion layer applied to the inner surface of a stainless steel or carbon steel substrate through a high-temperature sintering process. PFA offers excellent chemical inertness and thermal stability. The coating bonds firmly with the metal substrate, effectively isolating the metal from corrosive media and extending service life.

This product is suitable for corrosive media reaction and mixing processes in fine chemical synthesis, pharmaceutical intermediate production, new energy material preparation, and pigment/dye processing.

Key Advantages

1.Corrosion Resistance : PFA coating resists most strong acids (hydrochloric acid, sulfuric acid, nitric acid, etc.), strong alkalis, and organic solvents, suitable for various corrosive reaction media.

2.Temperature Resistance : The PFA coating operates stably from -80°C to +260°C and withstands thermal shock conditions.

3.Coating Adhesion : The spray application process ensures firm bonding between PFA and the vessel wall, preventing detachment or cracking, and capable of withstanding certain vacuum conditions.

4.Non-stick and Purity : Low friction coefficient of PFA facilitates material flow and discharge while reducing metal ion leaching—suitable for processes requiring high purity.

5.Customization : Vessels of various sizes and coating thicknesses can be customized to meet specific process requirements.
