Description
Technical field
The present invention relates to the technical field that conductive surface is processed is and in particular to a kind of cladding processing of plain conductor high polymer fills
Put.
Background technology
Modern industry requires more and more higher to the covering property of wire, and the cable of such as Qinghai-Tibet Plateau Railway, due to normal
Year is operated in the severe high and cold region of weather conditions, and therefore must have excellent anti-corrosion, cold-resistant, anti-ultraviolet performance will
Ask.Will be from the high polymer with preferable resistance to chemical attack, low temperature resistant and resisting environmental stress and cracking for this cable outer sheath material
Material such as high density polyethylene (HDPE), and add the filler (as carbon black etc.) of uvioresistant irradiation or add the 3- improving breaking resistance
The reinforcing fiber of 10mm.Conducting wire cladding technique：1. cladding in mould：When the wire of preheating enters die head of right angle, from extruder
Melt is just coated on wire.2. cool down：Wire with clad passes through cooling bath, and in cooling bath, water temperature gradient must be gradually
