Acrylic Resin And Acrylic Emulsion Reactor | JCT Machinery

August 20, 2025

Acrylic Resin ReactorAcrylic Emulsion Reactor
Reactor MaterialStainless steel reactor (usually SS304/316) must be solvent-resistant and corrosion-resistantStainless steel reactor, acid- and alkali-resistant and mechanically abrasive
Heating MethodHeat transfer oil or electric heating is often used to ensure high-temperature reactions (120-200℃)Typically steam or electrically heated, reaction temperature 70-95℃
Stirring DeviceBlades are typically anchor/frame/paddle/scraper-type with scraping to ensure uniform distribution of high-viscosity materialsMostly an anchor-type reactor with a disperser paddle, providing both dispersion and emulsification
Vacuum SystemVacuum system is often used to facilitate solvent removal and reduce bubblesGenerally not required or only used in certain processes
Cooling SystemRequired because rapid cooling is required after high-temperature polymerizationRequired to control the exothermicity of the emulsion reaction and prevent agglomeration
Auxiliary EquipmentSolvent recovery equipment, condenser, storage tank and filterEmulsifier batching tank, metering tank, emulsification and dispersion equipment and filter
Material ConditionThe product is a solvent-based resin with high viscosity, appearing as a transparent or translucent liquidThe product is a water-based emulsion, milky white or translucent, with good fluidity
Environmental RequirementsSolvent recovery and exhaust gas treatment requirements are high (VOC emissions)Water-based systems offer minimal environmental impact, but require wastewater treatment

Acrylic Resin Production Line Reactor
✅ Jacket heating (steam or thermal oil) is primarily used, sometimes with an internal coil heating system.

1. Acrylic resin synthesis is typically conducted at relatively high temperatures (120-250℃, depending on the type of thermosetting/thermoplastic resin).

2. Stable and uniform heating and insulation capabilities are required.

3. A thermal oil/steam heating jacket can maintain a constant temperature and high temperature for extended periods.

4. Some high-temperature resins (such as thermosetting acrylic resins) require a double jacket + coil heating system to improve heat exchange efficiency.
Acrylic Emulsion Production Line Reactor
✅ Jacket heating and cooling is primarily used, coils are rarely used.

1. Emulsion polymerization is generally an emulsion polymerization process, with relatively low reaction temperatures (around 70-95℃).

2. The reaction is exothermic, so cooling is more important than heating.

3. Circulating cooling water/hot water in the jacket is more suitable for controlling the exotherm of polymerization, preventing temperature overshoots during the emulsion polymerization process that can lead to agglomeration or side reactions.

4. Internal coils can easily cause material to adhere to the wall, making cleaning difficuly and detrimental to emulsion polemerization, and are therefore generally not used.
