Technical field
The present invention relates to processing of high molecular material technical field, and in particular to a kind of silanes crosslinked cable production line is with being followed by
Branch device.
Technical background
Chemical graft is one of most common method for being modified to polymer.It can change the property of polymer in itself
Can, its new function is assigned, the application field of polymer is expanded.Graft reaction is to pass through some groups for having specific function
The methods such as radical polymerization, ionic polymerization are grafted on the main chain of the strand of polymer or side chain, have polymer new
Characteristic.Common grafting method has fusion-grafting, solid phase grafting, solution graft copolymerization, irradiation grafting etc..
Fusion-grafting is wherein most easy industrialized production, and cost is minimum, a kind of higher grafting method of grafting rate, but this side
The more difficult control of the side reaction of method, the difficulties in dispersion of the trace assistant such as monomer, initiator, easily causes precrosslink, has experiment to show
It is grafted after being carried out to stranding wire rod, above mentioned problem can be prevented effectively from, but after rarer such equipment is dedicated for cable at present
Grafting.

Beneficial effects of the present invention are:
1st, grafting device is arranged on next process of extruder after electrical heating of the invention, can effectively reduce cable extrusion
Temperature, it is to avoid cable grafting process produces the technological deficiency of precrosslink.
2nd, the present invention effectively can anneal to cable, reduce cable stress.
3rd, temperature control system of the invention can be out of service when device temperature is too high, protection equipment, saves material.
4th, the present invention can improve extruder extruded velocity.
5th, the present invention is simple in construction, easy to maintenance, it is easy to operate.
