Resin Reactor Introduction | JCT Machinery

The Role of Resin in Glue

1. Film-forming and bonding

Resin is the primary film-forming substance in glue. After curing, it forms a strong adhesive layer, bonding two surfaces together.

2. Imparting mechanical properties

Determines the strength, toughness, and wear resistance of the glue.

3. Chemical and physical properties

Different resin types result in different glue properties, such as heat resistance, water resistance, and chemical resistance.

Structural Features of Resin Reactor

1. Corrosion-resistant materials

Stainless steel (SS304/316) is commonly used to prevent corrosion from acids, alkalis, and solvents in the resin raw material.

2. Hacket heating/cooling system

The jacket or inner coil can be heated with thermal oil electric heating, or steam to ensure precise and controllable reaction temperature.

Some resins require high-temperature polycondensation (around 200℃), so high-temperature resistance is crucial.

3. High-strength structure

Resin reactions often involve high viscosity and high reaction pressure (especially for some synthetic resins). Therefore, reactor body and support must be sufficiently strong and have high-quality welds.

4. Diverse mixing system

Commonly used mixing systems include anchor, paddle, frame, ribbon and disperser types, depending on the material viscosity and reaction stage.

High-viscosity resin can be equipped with variable frequency drive and dual mixing systems.

5. Good sealing performance

The top seal is typically mechanical or packing to prevent solvent evaporation and the ingress of external impurities.

6. Condensation reflux system

In solvent-based resin production, a top-mounted condenser and reflux line are installed to recover solvent and reduce emissions.

Performance Characteristics of Resin Reactor

1. Precise temperature control

Resin reaction temperatures fluctuate widely, and temperature control accuracy directly impacts molecular weight and performance.

High-quality reactors can achieve control accuracy of ±1-2℃.

2. High-temperature and pressure resistance

Adaptable to high temperatures of 200-250℃ (or even higher) and certain positive/negative pressure reaction conditions.

3. Efficient mixing and heat transfer

The jacket and mixing system combine to ensure uniform heating of the material, preventing local overheating and agglomeration.

4. Compatible with various resin production

One set of equipment can accommodate a variety of resin processes, including alkyd, unsaturated, acrylic and epoxy resin, providing a high return on investment.

5. Environmentally friendly and safety design

Enclosed reaction chamber reduces VOC emissions.

Equipped with a safety valve, bursting disc, and nitrogen blanketing system to prevent overpressure and oxidation.

Resin reactor's stirring system can be flexibly customized according to the material viscosity to ensure uniform reaction and stable product quality. It is also equipped with a condensation reflux and environmentally friendly emission system to help customers reduce energy consumption and emissions, and improve production efficiency and product competitiveness.
