SCP series high-viscosity self-cleaning reactor and large-capacity devolatilizer

SCP series high-viscosity self-cleaning reactor and large-capacity devolatilizer

SCP(Self-Clean Processor)new self-cleaning and devolatilier series, It integrates many advantages, such as self-cleaning and interface renewal ability of twin-screw extruder, large heat transfer area of thin film evaporator and large working volume of reactor. It is an ideal process equipment to realize the reaction polymerization, large capacity devolatilization, heat and mass transfer, distributed mixing, evaporation concentration, phase change crystallization, dissolution and swelling of all kinds of polymers (or other high viscosity material systems).

Case description:

Typical cases: trans-amyl rubber, hydrogenated butadiene rubber, biodegradable polyester polymerization devolatilization, waste recovery polyester alcoholysis polymerization granulation, ultra-high molecular weight polyethylene dissolution swelling.

The advantage and characteristic for SCP series high-viscosity self-cleaning reactor and large-capacity devolatilizer:

◆Across the short board of the twin-screw reactive extruder, SCP can significantly increase the working volume (up to more than 10m3) and the residence time of the material (up to several hours).

◆The specially designed differential meshing rotor can achieve good self-cleaning effect, and has better distributed mixing ability and interface renewal effect. Prevent dead zone and accumulation of scaling of materials, improve heat transfer, mass transfer and reaction process efficiency;

◆The main engine shell and rotor core can be heated and cooled, and the heat transfer area is larger.

◆Larger free cross-sectional area and gas phase space. The energy efficiency and stability of the large-capacity devolatilization operation are better.

◆The complex process with the change of phase state of material system can be realized.

◆The rotor is not in direct contact with the shell, the wear of the equipment can be significantly reduced.

◆The rotor can be designed by building block principle, and the related structure can be adjusted flexibly to meet the characteristics and needs of material process.

◆The lower shear rate and the soft kneading process significantly reduce the damage to the properties of sensitive materials, and at the same time, it is easy to achieve more accurate material temperature control.

The core extruder equipment includes parallel twin screw compounding extruder, reciprocating

compounding kneader, double rotor compounding extruder, SCP high viscosity self cleaning

reactor and large capacity devolatilizer, etc.

At the same time, based on the above main extruder, the design and manufacture of a

complete set of compounding pelletizing production line equipment and compounding

extrusion forming production line equipment can be realized. It is mainly used in the fields

of engineering plastics, modified plastics, wire and cable materials, rubber, packaging,

building medical chemical industry, chemical fiber textile, household appliance and other

industries (see the application case for details).

The existing factory area of the company is 46500 m2 (of which the parent company is

38000m2, and the subsidiary (Nanjing Cenmen) is 8500m2), The core parts and system

of the extruder are designed and manufactured by the company, such as barrel, screw,

gear box, etc. The company has advanced NC machining center, NC screw grinder,

CNC machine tool and other machining equipment. Equipped with Swiss imported

three-coordinate detector and Japanese imported spectral detector and other

advanced inspection and testing equipment. There are complete quality control means

and system from processing to testing, which fully ensure the stability and reliability of

product quality.

The extruders produced by Cenmen company are exported to nearly 40 countries, such as

Germany, Russia, belarus, Japan, Korea, Israel, Ukraine, magiddon, Iran, Thailand, Indonesia,

Brazil, India, Mexico, South Africa, etc.
