Description
Technical field
The present invention relates to a kind of PVC cable duct tubes inner tube and preparation method thereof.
Background technology
The pipe material that in the market is used as plastic cable protection substantially has two major classes, and one kind is thermosetting plastics, wherein
Based on GRP pipe, another is thermoplastic, based on PVC, polyethylene, PA tube.This two big types of material
Pipeline advantage and disadvantage it is as follows：
The advantage in frp cable protective pipe road：(1) GRP pipe is lightweight, rigidity is high, resistance to compression and anti-settling ability
By force；(2) thermal conductivity factor is big, and the especially long-term advantage when underground is run of cable becomes apparent from；(3) the resistance to temperature difference is good, -40 DEG C~-
Service life was up to 50 years in 150 DEG C of environment.Frp cable protective pipe road is rough due to technique defect itself and illegal producer
Make excessively, no alkali product is served as with high alkali product, the factor such as adulterate, its quality is uneven, and traction steel is cannot stand when wearing cable
Friction, the scuffing of silk, result in glass fibre delamination, cause glass fibre to be entangled on cable, twine more and more, can neither advance,
It can not retreat, cause to wear cable failure, it is impossible to realize that safety wears the purpose of cable, be faced with the danger being eliminated.
The advantage of the thermoplastic pipes such as PVC, polypropylene, polyethylene is a lot, applies in cable protection field, outstanding feature is just
It is good electrical insulating property, inwall smoother, easy cabling, the phenomenon for not resulting in stuck cable occurs.But it is heat-resisting, cold-resistant
There is limitation, it is difficult to the need for reaching power industry technical requirements.Thermoplastic tubing is the relatively common tubing of in the market above,
Respectively there are advantage and disadvantage, but fallen far short apart from the requirement of power industry.
Existing PVC cable duct tubes inner tube is because the deficiency that component and preparation technology are present, has poor-performing, it is impossible to
The problem of possessing stronger advantage in market competition.
The content of the invention
It is an object of the invention to provide a kind of PVC cable duct tubes inner tube, existing PVC cable duct tubes inner tube is solved because group
