resin reactor

How does an epoxy resin production line work?

Through a precise, automated, and sealed process, liquid epoxy resin (Part A) is uniformly mixed with a curing agent (Part B) and other additives in the correct proportions under a controlled environment. Air bubbles are removed, resulting in a homogeneous, ready-to-use product.

How to effectively remove bubbles in epoxy resin production?

The main mixing vessel itself is designed with a vacuum-capable structure, enabling integrated mixing and initial degassing.

A dedicated vacuum degassing vessel is connected in series after the mixing vessel for advanced degassing.

For continuous production lines, an inline vacuum degassing system is used.

The mixing and degassing vessels are equipped with a precise jacket temperature control system (mold temperature controller) to achieve precise control of heating and viscosity reduction.

The filling machine uses bottom filling or pressure filling to prevent the generation of new bubbles during the filling process.

How can epoxy resin production line control temperature to prevent over-reaction？

1. Reactor with jacket and pipe coil

The jacket and internal pipe coil can be used as heating or cooling circuits, providing a large heat exchange area.

2. Thermal oil/steam and cooling water

The thermal oil is used for high-temperature heating, while cooling water/cooling tower is used for rapid heat release; low-temperature chiller can be used as an auxiliary device if necessary.

3. Heat exchanger (plate or shell and tube)

Used to extract high-temperature media from the reactor circuit for side cooling or heat recovery.

4. Forced circulation pump and bypass cooling circuit

Ensure sufficient flow rate in the jacket or pipe coil to prevent local overheating.

5. Rate-limited dosing

Add reactants and curing agent in stages to control the instantaneous heat release rate and avoid dosing all at onece.

Use a metering pumo and a gradual dosing strategy (e.g., dosing according to a rate curve) for the curing agent/catalyst.

What is the difference between fully automatic and semi-automatic epoxy resin production line?

Customer type	Recommended production line type	Reason
Large-scale chemical plants/resin exporter	Fully automatic	Strong stability, consistent quality, labor savings, and easy management and traceability
Small- to medium-sized plants/multi-product small-batch production company	Semi-automatic	Low cost, high flexibility and easy process adjustment
R&D institution/laboratory	Semi-automatic	Suitable for frequent recipe changes and process validation
Company planning gradual upgrading	Semi-automatic + reserved automation interface	Fully automated upgrades with the ability to add weighing modules and PLC systems later
