Umkhono oshwaqa ukushisa (noma ngokuvamile “umkhono oshwabene”) uyisivikelo esivikela ukugqwala samapayipi ngendlela yokugoqa noma umkhono weshubhu osetshenziswa ensimini.
PTFE ukushisa shwabanisa sleevingyenziwe nge-PTFE emsulwa engenazo izithasiselo noma izithasiselo ngakho-ke inikezela ngazo zonke izici ezihlukile ze-PTFE.
Isici esiyinhloko salokhu kuncipha kokushisa okuphezulu izinga lokushisa eliphezulu eliqhubekayo lokusebenza elingu-260°C.
I-PTFE i-sleeving yokunciphisa ukushisa yenziwe nge-PTFE emsulwa engenazo izithasiselo noma izithasiselo ngakho inikezela ngazo zonke izici ezihlukile ze-PTFE.
Lokhu kudlula okwanoma iyiphi enye i-polymer yokunciphisa ukushisa.Ngaphezu kwalokho, imelana ngokuphelele nawo wonke amakhemikhali, nemisebe ye-UV.Itholakala ngezilinganiso ze-4:1 kanye ne-2:1 shrink, futhi izinga lokushisa elinciphayo lingu-327°C.
Idatha Yezobuchwepheshe:Khetha umkhono olungile wosayizi ngokuvumela inani elikhulu lokushwabana, kunokusebenzisa umkhono oqinile uma kungenzeka.I-PTFE incipha emazingeni okushisa angaphezu kuka-330°C, ngakho izinga lokushisa lesibhamu kufanele okungenani libe ngu-400°C.Ukuthola izinga lokushisa eliphezulu siphakamisa isibhamu somoya oshisayo esingu-1.5KW umthamo.Izingxenye okumele zimbozwe ezinesisindo esikhulu esishisayo, isb irola yensimbi eqinile, ingase idinge ukushisisa ngaphambili lapho kufakwa ukushisa kwe-PTFE, ukuvimbela ukugodola komkhono we-PTFE, okubangela ukulingana okuxekethile.
