Silane XLPE Cable Compounding Extrusion Pelletizing Line

Two -step extrusion pelletizing equipment for silane XLPE cable below 10KV

Description of two-step production process

The silane is grafted onto the PE main chain by DCP as an initiator, and the grafting A material is finished on the compounding extruder. At the same time, the catalyst masterbatch (containing PE, catalyst, antioxidant) B is completed on a compounding extruder or a small size compounding extruder. According to the proportion of 95:5, the A and B materials are mixed evenly, the extrusion discharge is completed on the single screw extruder of the special extruder, and then the finished product is crosslinked in warm water.

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.
