Different Reactor For Different Resins Production

Different Types of Reactors and Applicable Impeller Structures

Reactor type	Feature	Common propellant type	Suitable resins for production
Stainless steel jacket reactor	Uniform heat transfer, suitable for high-temperature and high-pressure operations	Paddle, anchor, frame	Epoxy resins, phenolic resins, alkyd resins
External coil reactor	Large heat transfer area, suitable for high-temperature polycondensation reactions	Anchor+frame combination	Unsaturated polyester resins, alkyd resins
Internal coil reactor	High internal heat exchange efficiency, more precise reaction temperature	Frame, ribbon	Acrylic resins, polyurethane resins
Vacuum reactor	Capable of dehydration, degassing and solvent removal	Ribbon, pusher	Waterborne resins, acrylic emulsions, PVA glue

Analysis of Impeller Types and Mixing Characteristics

1. Anchor type

Structure: Rotates around the kettle wall, resembling a ship's anchor.

Characteristics: Suitable for medium to high viscosity materials; scrapes the kettle wall to prevent coking.

2. Frame type

Structure: Similar to a rectangular frame, with wide blades.

Characteristics: Uniform mixing, low shear; suitable for reaction systems with large viscosity variations.

3. Propeller type

Characteristics: High shear force, good flowability; suitable for low viscosity systems.

4. Ribbon type

Characteristics: Circulates material vertically, preventing stratification.

If the type of reactor and impller does not match the characteristics of the material, it will directly affect the reaction efficiency, product quality, and may even load to equipment damage or safety hazards.
