Case description

In the process of various reaction polymerization, large-capacity devolatilization, heat and mass transfer, mixing and kneading, evaporation concentration, phase change crystallization and many other harsh conditions, the material already has a certain viscosity, and with the progress of the reaction or the improvement of the solidification content, the polymer melt viscosity will also be greatly increased to become a medium and high viscosity material. Conventional vertical reactors, tubular reactors and other equipment will greatly reduce the mixing effect and self-cleaning ability, resulting in reduced polymer production efficiency, wide molecular weight distribution, unstable quality, and serious cases may lead to the normal operation of the equipment.

In response to the above-mentioned problems of medium and high viscosity materials, Cenmen Company designed a new type of horizontal self-cleaning reaction/ devolatilization equipment after digesting the design principles of foreign manufacturers and combining years of experience in the application of reaction/ devolatilization materials.

Typical application of continuous polymerization devolatilization and viscosification extrusion equipment：

Process	Typical application	Production process characteristics
Various polymer materials polymerization reaction	Polycondensation or other bulk polymerization：PBAT、PLGA、PET、PMMA、trans-butadiene rubber、PGA、PLA、PCL、bulk polymerization ABS, etc.	The continuous production process of the horizontal reactor has high production efficiency and stable product performance. During the polymerization reaction, the temperature gradient is small, the residence time distribution is small, the molecular weight distribution is narrow, the polymerization yield is high, and it is easy to obtain high molecular weight polymers.
	Solvent polymerization: various synthetic rubbers, TPE elastomers, etc.
High-capacity polymer devolatilization (50~80% volatile content)	Polymer, synthetic rubber or elastomer solvent removal: such as hydrogenated butadiene rubber, POE elastomers, various styrene-butadiene copolymers, butyl rubber, SBS/SEBS, acrylates, etc.	In the process of high solvent (30-90%) devolatiling and viscosity increasing, the high solvent gas phase conversion can be completed in a short time (20-50 minutes), and the deep devolatiling and discharge of high boiling point polymerization residual by-products can be continuously completed (volatile content 0.03-0.5% after devolatiling).
	Removal of residual monomer: such as PPC resin, silicone rubber, etc

Typical technical parameter range of horizontal reactor:

Viscosity range of applicable materials: 5-20000Pa.s

Operating temperature range: 0-300℃

Residence time range: 0.1-5h

Heat exchange area range: 0.3-62m2

Working volume range: 5.5-17175L

Operating pressure range: 0.1MPa-200Pa absolute pressure
