Whatis a PFA Coated Chemical Mixing Tank?

A PFA coated chemical mixing tank is a steel vessel with a sprayed PFA layer that combines the mechanical strength of metal with exceptional chemical resistance. The PFA coating creates a protective barrier against corrosion, preventing reactive chemicals from contacting the metal substrate. This tank is designed for mixing, blending, heating, and storing aggressive chemicals that would otherwise damage conventional equipment.

Spray Coating Process

Zhuoyan employs a rigorous multi-step spray coating process to ensure superior quality and durability:

Step	Description
1. Material Inspection	Inspect shell welds and surface quality
2. Grinding	Remove burrs, finish weld seams
3. High-Temperature Degreasing	Bake at high temperature to remove surface oils
4. Sandblasting	Sandblast to Sa2.5 grade for enhanced coating adhesion
5. Surface Cleaning	Thoroughly remove sandblasting dust
6. Preheating	Preheat metal substrate to spraying temperature
7. Primer Application	Apply primer layer for enhanced bonding
8. Primer Drying	Cure primer at high temperature
9. Topcoat Application (6 repeated coats)	Spray PFA multiple times with sintering after each coat
10. High-Temperature Sintering	Metallurgical bonding of coating to substrate
11. Appearance Inspection	Visual inspection of coating quality
12. Coating Thickness Measurement	Gauge measurement of coating thickness
13. Spark Testing	High-voltage spark test for pinhole defects
14. Adhesion Testing	Coating bond strength test
15. Inner Surface Cleaning	Final cleaning of finished product
16. Packaging	Pearl cotton wrap + wooden crate/steel frame

FAQ

Q1: What is the difference between PFA and PTFE coating?

A1: While both are fluoropolymers, PFA offers better melt-processability and typically provides a smoother, more pinhole-free coating. PFA is also preferred for high-purity applications due to lower extractable levels.

Q2: What is the maximum operating temperature?

A2: PFA coated tanks can operate up to 260°C, depending on the specific PFA grade and application conditions.

Q3: Can the tank be customized to specific sizes?

A3: Yes, Zhuoyan offers custom engineering services for tanks ranging from 10L to 50,000L.

Q4: How is the coating quality verified?

A4: Zhuoyan conducts electrical discharge testing (spark testing) to detect pinholes, coating thickness measurement, and adhesion testing to ensure quality.
