Ezinhlelweni zokudlulisa uketshezi, amapayipi asebenza njengebhuloho elibalulekile phakathi kwemishini kanye nabezindaba, futhi ukusebenza kwabo kuthinta ngokuqondile ukuzinza nokuphepha kwesistimu ye-PTFE hoses namapayipi e-PVC, njengezinhlobo ezimbili ezivamile zezinto ze-hose, ngayinye inezinzuzo eziyingqayizivele kanye nezicelo. Ukuqonda umehluko phakathi kwazo kungasisiza senze izinqumo ezinengqondo ezisekelwe ezidingweni zangempela.
- Ukwakheka kwamakhemikhali nokuzinza
Ipayipi le-PTFE lenziwe ngezinto ze-polytetrafluoroethylene, ezinokuzinza kwamakhemikhali okuphezulu kakhulu futhi cishe azithintwa yinoma yiziphi izinto. Ingakwazi ukumelana nokuhlasela kwemithombo yezindaba ezonakalisayo njengama-asidi, ama-alkali, nosawoti. Isakhiwo sayo samangqamuzana asinawo amabhondi e-carbon-carbon double ngakho inokumelana ne-oxidation ephezulu. Ngokuphambene, ipayipi le-PVC liyi-resin yokwenziwa eyenziwe nge-polymerized kusuka ku-vinyl chloride monomers. Nakuba futhi inokumelana nokugqwala okuhle kokuzinza kwayo kwamakhemikhali kanye nokumelana ne-oxidation kuphansi uma kuqhathaniswa. Lo mehluko wenza ipayipi le-PTFE libe nenzuzo kakhulu ezindaweni ezigqwala kakhulu.
- Izici zokusebenza
Amapayipi e-PTFE asebenza kahle ngokulinganayo ngokusebenza. Izindonga zabo zangaphakathi zibushelelezi nge-coefficient ephansi ye-friction, enganciphisa ngempumelelo ukumelana ngesikhathi sokunciphisa nokunciphisa ukugqokwa kwemishini. Ukwengeza, amapayipi e-PTFE anokumelana okuhle kakhulu nokushisa okuphezulu nokuphansi, okubavumela ukuthi basebenze ngokuzinza ebangeni elibanzi lokushisa -250℃ kuya ku-260℃ ngaphandle kokuba brittle noma ukuguga. Ngakolunye uhlangothi, amapayipi e-PVC, ngenkathi enokuguquguquka okuthile futhi aqinile, athambekele ekuguquguqukeni emazingeni okushisa aphezulu, anciphisa ukusetshenziswa kwawo ezindaweni ezishisa kakhulu.
Amapayipi e-PTFE, ngenxa yokuzinza kwawo okuhle kakhulu kwamakhemikhali, ukumelana nokushisa okuphezulu, nokumelana nokugqoka, asetshenziswa kakhulu ezimbonini ezifana namakhemikhali,, igesi yemvelo, ukudla, kanye nemithi lapho kudingeka khona izinto ezisebenza kakhulu zamapayipi. Afaneleka ngokukhethekile ukuphatha imidiya ebolayo kanye nezindawo ezinomfutho ophezulu. Ngakolunye uhlangothi, amapayipi e-PVC, anezindleko eziphansi kanye nokusebenza okuhle kokucubungula, asetshenziswa kakhulu ekwakhiweni kwe-drainage, umoya omncane, izinhlelo zokuhlinzeka ngamanzi, kanye nasezindaweni ze-electronics lapho ukufakwa okuguquguqukayo nokulawulwa kwezindleko kuyadingeka. Kunomehluko omkhulu ezimpahleni ezibonakalayo nasezinkundleni zokusetshenziswa phakathi kwalokhu kokubili.
Sengiphetha, siphinde sigcizelele ukuhluka nokuhambisana kwalezi zinto ezimbili zamapayipi. Amapayipi e-PTFE, anokuqina kwawo okuhle kakhulu kwamakhemikhali okushayisana okuphansi kwe-coefficient, kanye nokumelana nezinga lokushisa eliphezulu naphansi, asephenduke into ethandwayo yokukhiqiza okuphezulu kanye nezimo zokusebenza ezimbi kakhulu. Ngakolunye uhlangothi, i-PVC, ngokusebenza kahle kwayo kwezindleko kanye nokucutshungulwa kalula, bathole indawo yabo ezinhlobonhlobo zezimboni. Ukukhetha ukuthi iyiphi ipayipi okufanele isetshenziswe akukhathazi kuphela ukusebenza kahle kodwa nokusebenza okuphelele nokuphepha kwesistimu.
