Characteristic.But it is poor that its weak point is comprcssive strength, requiring also have gap with construction application, its fire resistance is the most not ideal enough；Separately
Its vicat softening temperature outer is hovered at about 90 DEG C, and inner and outer pipes wall friction coefficient is big, adds the difficulty of construction usage.
MPP power cable protecting pipe is divided into digging type and no-dig technique type, and MPP power cable protecting pipe uses modified polypropene
For main raw material(s), it is need not to dredge in a large number, cut the earth and destroy road surface, inferior distinguishingly in road, railway, building, riverbed
The section construction work such as roughing-in, cable.Compared with traditional " grooving pipe laying method ", no-dig technique power pipe engineering more adapts to currently
Environmental requirement, remove because of traditional construction caused stir up a cloud of dust, the factor that disturbs residents such as traffic jam, this technology can also be
Some regional pipeline installations that cannot implement to excavate operation, such as paleovolcanic structure district, business district, crops and farmland protection area, height
Speed highway, river etc..MPP power cable protecting pipe has the feature of high temperature resistance, proof to external pressure, it is adaptable to more than 10KV high voltage power transmission
Line cable duct bank tubing.
Glass fibre is the Inorganic Non-metallic Materials of a kind of excellent performance, of a great variety, and advantage is good insulating, thermostability
By force, corrosion resistance good, mechanical strength is high, but shortcoming is that property is crisp, and wearability is poor.It is with glass bead or discarded glass as raw material
Being manufactured into through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth, a diameter of several microns of its monofilament to twenties meters are micro-
Rice, is equivalent to the 1/20-1/5 of a hairline, and every bundle fiber precursor is all made up of hundreds of the most thousands of monofilament.Glass
The national economy such as fiber is typically used as the reinforcing material in composite, electrically insulating material and heat-insulating material, circuit substrate
Every field.
