Iipayipi zePolytetrafluoroethylene (PTFE) zisetyenziswa kakhulu kwishishini leemoto ngenxa yeempawu zazo ezikhethekileyo ezifana nokumelana noxinzelelo oluphezulu kunye nobushushu, ukungangeni kweekhemikhali, kunye nokungqubana okuphantsi. Ezi payipi zisetyenziselwa usetyenziso olwahlukeneyo kubandakanya iintambo zepetroli, iintambo zeebhuleki, iintambo zevacuum, kunye neepayipi zokupholisa. Nangona kunjalo,Iipayipi ze-PTFEzingahlulwahlulwa ngokubanzi zibe ziintlobo ezimbini: eziqhuba umbane kunye nezingaqhubiyo. Umahluko ophambili phakathi kwezi ntlobo zimbini zeepayipi kukuqhubiyo kombane, okudlala indima ebalulekileyo ekusetyenzisweni nasekusebenzeni kwazo. Apha ngezantsi siza kuxoxa ngomahluko phakathi kweepayipi zePTFE eziqhuba umbane kunye nezingaqhubiyo ekusetyenzisweni kweemoto.
Iipayipi zePTFE ezingaqhubiyo
Ni-on-conductor Iipayipi ze-PTFE AZINAYO i-conductive liner. Oku kuthetha ukuba aziqhubi (zichitha) umbane kwaye azinakusetyenziswa kwiindawo ezifuna ukugqunywa. Ukunqongophala kwezixhobo zokuqhuba umbane kwiokungekho mqhubi Iipayipi ze-PTFE zizenza zikwazi ukumelana neekhemikhali ezithile kunye nezinyibilikisi ezinokuhlasela iikhompawundi ezikwiipayipi ze-PTFE eziqhuba umbane. Oku kuzenza zilungele ukusetyenziswa kwiindawo ezifuna ukuchatshazelwa ziikhemikhali ezirhabaxa okanye izinyibilikisi.okungekho mqhubi Iipayipi ze-PTFE zikwanayo ne-coefficient ephantsi yokungqubana xa kuthelekiswa neepayipi ze-PTFE eziqhubayo, nto leyo eyenza ukuba zilungele ukusetyenziswa kwiindawo apho uxinzelelo oluphezulu kunye nokunciphisa ukungqubana kubalulekile. Oku kuquka izicelo ezifana neebhuleki, i-clutch, i-hydraulic, kunye ne-vacuum lines.
Nangona kunjalo, enye yezona zinto zingalungangaokungekho mqhubi Iipayipi ze-PTFE kukungakwazi kwazo ukukhupha itshaja engashukumiyo. Oku kuthetha ukuba azinakusetyenziswa kwiindawo ezifuna umhlaba, njengeentambo zepetroli. Kule ndawo, ukuqokelelana kwetshaja engashukumiyo kunokuba yingozi kwaye kunokubangela ukuqhuma ukuba akuchithwanga kakuhle.
Iipayipi zePTFE eziqhubayo
Iipayipi zePTFE eziqhubayo zezo zine-conductive resin liner, ezivumela ukuba ziqhube umbane. Olu hlobo lwepayipi luhlala lusetyenziswa kwiindawo ezifuna ukugqunywa. I-conductive lining inika indlela yokuba umbane ongashukumiyo uphume kwipayipi, uthintele ukwakheka kwe-static charge. Ukwakheka kwe-static charge kunokuba yingozi kwiindawo ezithile apho intlantsi inokutshisa ipetroli kwaye ibangele ukuqhuma, nto leyo eyenza i-conductive liner ifaneleke ukusetyenziswa kwimigca yamafutha esebenzisa igesi, i-E85, i-methanol nezinye.
I-liner eqhubayo kwiipayipi ze-PTFE idla ngokwenziwa ngomnyama wekhabhoni, nto leyo enika i-conductivity kwizinto ze-PTFE kwaye iyinike umbala ongwevu ocacileyo. I-liner ifakwe kwizinto ze-PTFE ngexesha lenkqubo yokwenziwa, ukuqinisekisa i-conductivity efanayo kulo lonke ubude bepayipi.
Isiphelo
Iipayipi zePTFE eziqhubayo nezingaqhubiyo ziintlobo ezimbini zeepayipi ezisetyenziswa kakhulu kwishishini leemoto. Umahluko ophambili phakathi kwezi ntlobo zimbini zeepayipi kukuqhubi kwazo ngombane, okudlala indima ebalulekileyo ekusetyenzisweni nasekusebenzeni kwazo. Kungenxa yesi sizathu iBesteflon inikezela ngepayipi engaqhubiyo kuthotho lwethu lwe--ZXGM, ngelixa uthotho lwe--ZXGMB ngoku luza kumgangatho ophezulu kwiPTFE eqhubayo kucingelwa ukhuseleko. Zombini ezi ntlobo zeepayipi zinocingo lwangaphandle olungenasici olunika ukuqina okongeziweyo kwipayipi, okwenza ukuba imelane ngakumbi neekinks, ukukrazula, kunye nokubhoboza. Oku kwenza iipayipi zePTFE zilungele ukusetyenziswa kwiindawo ezinzima, njengaphantsi kwehood yemoto, apho zinokuchaphazeleka kubushushu obuphezulu, iikhemikhali, kunye noxinzelelo loomatshini ngelixa zihlala ixesha elide kuneepayipi zangaphakathi zeCPE eziqhelekileyo. Zombini ezi ntlobo zeepayipi zineengenelo kunye neengxaki zazo, kwaye kubalulekile ukukhetha uhlobo olufanelekileyo lwepayipi kwisicelo ngasinye ukuqinisekisa ukusebenza okukhuselekileyo nokusebenzayo.
Yasekwa e2005,NgaphezuluIminyaka engama-20 yamava okuvelisa, I-Besteflon iye yaba ngumvelisi kunye nomthengisi weepayipi ze-PTFE othembekileyo eTshayina. Iipayipi zethu zakhiwe ngezinto ze-PTFE zekhwalithi ephezulu kunye nokuluka kwentsimbi engagqwaliyo ekumgangatho ophezulu, okuqinisekisa:
·Ukumelana noxinzelelo oluhle kakhulu kunye nokuguquguquka
·Ubomi benkonzo obude xa buthelekiswa neepayipi eziqhelekileyo
