It connects.All there is certain defect in polyether-ether-ketone splicing in the above connecting method.Such as：Relatively conventional PPR（Random copolymerization
Polypropylene）It is all made of the mode of melting splicing, but polyether-ether-ketone melting temperature itself is excessively high, simultaneously because hemicrystalline property itself
Can, joint strength is unable to get effective guarantee, while joint strength is well below the intensity of material itself, therefore not applicable；
The mode of mechanical splice certainly will will be punched in polyetheretherketonematerials materials, to weaken the intensity of material itself；Due to poly-
The high corrosion resistance of ether ether ketone itself still can not find a kind of adhesive that can effectively dissolve polyether-ether-ketone at this stage.
In this case, research and development have very crucial meaning suitable for the ultrasonic welding process of polyether-ether-ketone.
