Umtywini womtywini wetywina, ifilimu ye-polytetrafluoroethylene, inamagama amaninzi asetyenziswa ngokuqhelekileyo afana ne-PTFE tape kunye ne-tape dope.Iteyiphu ye-PTFE ibonelela ngesitywini esiyimfuneko kunye nokuthambisa kwimisonto yombhobho kwaye yenye indlela ngamanye amaxesha omdaka wombhobho wedope.Iteyiphu ye-PTFE iza ngemibala eyahlukeneyo, equka ngokubanzi emhlophe, emthubi kunye nohlaza ukuze ihambelane ne-US kunye nemibhobho ekhowudiweyo yombala waseKhanada.Iteyiphu emhlophe ilungele imisebenzi esisiseko yemibhobho yamanzi ngelixa eminye imibala eqhelekileyo, efana neteyiphu etyheli ibonelela ngoxinaniso oluphindwe kabini kwaye isetyenziselwa imibhobho yerhasi kunye neteyiphu eluhlaza inikezela ngoxinaniso oluphindwe kathathu lwemibhobho yeoksijini.
Iteyiphu yokutywina ngomsonto(ekwaziwa ngokuba yi-PTFE tape okanye iteyiphu yomtywini) yifilimu ye-polytetrafluoroethylene (PTFE) esetyenziselwa ukutywina imisonto yombhobho.Iteyiphu ithengiswa isikwe kububanzi obuthile kwaye inxeba kwi-spool, okwenza kube lula ukujikeleza imisonto yombhobho.Ikwaziwa nangeteyiphu yepolymer eyenziwe yafana neyorhwebo;ngelixa i-polymer eneneni ifana ne-PTFE, i-Chemours (abanini-mpawu zorhwebo) bathathela ingqalelo oku kusetyenziswa akuchanekanga, ngakumbi njengoko bengasakwazi ukwenza i-polymer ngendlela yeteyiphu. imisonto ekubambeni xa u unscrewed.Iteyiphu kwakhona isebenza njenge filler deformable kunye nelubricant intambo, inceda ukutywina umdibaniso ngaphandle kokuqina okanye ukwenza kube nzima ngakumbi ukuqinisa, kwaye endaweni yoko ukwenza kube lula ukuqiniswa.
Ngokuqhelekileyo iteyiphu isongelwe kumsonto wombhobho izihlandlo ezithathu phambi kokuba ijijwe endaweni yayo.Ngokuqhelekileyo isetyenziselwa urhwebo kwizicelo ezibandakanya iinkqubo zamanzi ezinoxinzelelo, iinkqubo zokufudumeza eziphakathi, kunye nezixhobo zoxinzelelo lomoya.
Iteyiphu yomsonto ifanelekile ukuba isetyenziswe kwimisonto ekhutshiweyo, apho amandla okutywina ayisenzo se-wedge.Imisonto ehambelanayo ayinakutywinwa ngokufanelekileyo kunye okanye ngaphandle kwe-tape, njengoko ihloselwe ukutywinwa nge-gasket.
Iteyiphu yokutywina imisonto iphantse isetyenziswe ngesandla, nangona kukho umatshini omnye okhoyo wokusonga imveliso yezinto zokufakelwa.
Iteyiphu ye-PTFE ikwasetyenziswa ngokuqhelekileyo ukolula kokugqojozwa komzimba, ngenkqubo eyaziwa ngokuba yiteyiphu, kuba ayisebenzi kwaye ikhuselekile kolu setyenziso.Umntu onxibileyo ubhinqisa iileyile zeteyiphu ejikeleze iplagi, enyusa kancinci ubungakanani kwaye ngaloo ndlela enyusa kancinci ubungakanani (igeyiji) yokugqobhoza.
