Izindaba - Iyini Ipayipi le-PTFE Elukiwe Insimbi Engagqwali |I-BESTEFLON

Iyini iHose ye-PTFE Eyenziwe Ngensimbi Engagqwali

Amapayipi e-PTFE aqale asetshenziswa kumasistimu asebenza ngamanzi noma omoya noma emkhakheni we-aerospace futhi asheshe aduma.Amapayipi namashubhu enziwe nge-polytetrafluoroethylene asebenza kahle ngaphansi kwezimo zemvelo nezimboni eziyinselele, ngakho ukusetshenziswa kwawo kwezentengiso embonini kuyanda.Ngenxa yokutholakala kwayo okuphezulu kwezohwebo nokusebenza kwayo okuhle kakhulu, imikhiqizo ye-PTFE iyimpahla ebalulekile ezimakethe zezimboni, zezokwelapha kanye nabathengi, lapho isetshenziswa khona hhayi kuphela ezindleleni zendabuko, kodwa nasezindleleni ezingezona ezendabuko nezingajwayelekile.

Iyini ipayipi le-PTFE elilayishiwe

IIpayipi le-PTFEiyishubhu elakhiwe ulayini lwe-PTFE lwangaphakathi kanye nekhava yangaphandle eyisivikelo.Ulayini we-PTFE ufana neshubhu le-PTFE elinesembozo sokuvikela sangaphandle, okwandisa ukumelana nokucindezela.Inhlanganisela yekhava yangaphandle kanye ne-PTFE liner yangaphakathi yenza ipayipi libe ithuluzi elibalulekile ezinhlelweni eziningi

Izici zepayipi le-PTFE

Ipayipi le-PTFE linezici ezilandelayo:

Ukumelana nokushisa nokumelana nokubanda

isilondolozi

Abukho ubuthi, ubumsulwa obukhulu

I-permeability ephansi kakhulu

Anti-ukukhathala

Isisindo esincane

Ilungele ukubulala amagciwane nokuhlanza

Ukumelana ne-UV ne-ozone

Inert ngamakhemikhali

Ukumelana namanzi

Ukumelana nomthelela

i-anti-static

i-lassification yamapayipi we-PTFE

Izici ezilandelayo zidinga ukucatshangelwa kumashubhu e-PTFE lapho uzikhethela uhlelo oluthile

Uhlobo olubushelelezi noma oluhlanganisiwe: Izinto eziyinhloko ezihlukanisayo esimweni samapayipi e-PTFE irediyasi egobayo nosayizi.Indawo yokuvula imbobo ebushelelezi ingaphansi noma ilingana neyintshi eyodwa.Ngesikhathi esifanayo, i-radius egobile ye-hose ebushelelezi izoba yincane kunawo wonke ama-intshi angu-12, futhi imbobo yokugoba izoba yincane kakhulu amayintshi angu-3.

Okungaconductive noma okuqhubayo: Ishaja engaguquki inkokhiso ekhiqizwa into ethile emaphakathi uma inkokhiso igeleza ngepayipi le-PTFE ngesivinini esikhulu.Uma uziba lezi zindleko ze-electrostatic, kungase kubangele izimo eziyingozi njengokuqhuma.Ngakho-ke, amapayipi e-PTFE ngezinye izikhathi enziwa ngezinto ezikhethekile zokulwa ne-static ukuze kugwenywe ukunqwabelana kukagesi omile

Ugqinsi lodonga lwepayipi le-PTFE: ukujiya kodonga lwepayipi eboshwe nge-PTFE kuhlukile.Ezinsizeni lapho amapayipi egobe kakhulu, izindonga eziwugqinsi yizona ezikhethwa kuqala ngoba zinokumelana okungcono nokugoba.Izindonga eziwugqinsi zepayipi nazo zihlinzeka ngokungena kancane kwegesi, kodwa zithatha indawo eyengeziwe

Izinto zokuluka: Ukuluka kwensimbi engagqwali okungu-304 kuvame ukuba yimpahla ekhethwayo ezimweni eziningi.Kodwa-ke, ngezinhlelo zokusebenza zasolwandle, sebenzisa uhlobo lwe-316 eluka insimbi engagqwali.Ngaphezu kwalokho, uma ipayipi lizosetshenziswa endaweni egqwala kakhulu, umluko osetshenziswayo kufanele wenziwe ngensimbi engagqwali.Ngaphezu kwalokho, i-braid kufanele yenziwe ngethusi, uma kwenzeka i-hose izosetshenziswa endaweni ephikisanayo kakhulu ngenxa yezakhiwo zayo ezinhle zokugcoba.

Ukusetshenziswa kwepayipi le-PTFE

Indawo yokuhluza uwoyela negesi

Imboni Yensimbi

I-power plant

Isigayo samaphepha

Imboni yezemithi

Imboni kamanyolo

Imboni yamakhemikhali

I-boiler yezimboni

I-air conditioning nesiqandisi

Isikhungo senuzi

imboni yezimoto

Amachweba nezindawo zemikhumbi

Ngokukhetha ipayipi elifanele le-PTFE, imboni ingasebenzisa ikhwalithi enhle kakhulu ye-PTFE futhi ithole izinzuzo eziningi kuyo.Ukukhetha impahla efanele kuzoholela ekusebenzeni okungcono futhi ekugcineni izindleko eziphansi zobunikazi, kungakhathaliseki ukuthi umkhiqizo usetshenziswa kuphi.

Ipayipi le-PTFE elilukiwe ngensimbi engagqwali (i-conductive core)

Ipayipi le-PTFE elilukiwe ngensimbi engagqwali(i-conductive core) i-PTFE engazweli ngamakhemikhali icishe ikhululekile kuwo wonke amakhemikhali entengiso, ama-acids, utshwala, izipholile, ama-elastomers, ama-hydrocarbon, izinyibilikisi, izinhlanganisela zokwenziwa kanye nemithelela kawoyela we-hydraulic.Ikwazi ukumelana nezinga lokushisa eliphezulu, ingakwazi ukuphatha yonke into kusukela kumazinga okushisa aphansi kuya ku-steam konke ngepayipi elilodwa.Izinga lokushisa lingu -65°~450°.Ngenxa yezakhiwo zokulwa nenduku ze-PTFE, izinga lokugeleza okuphezulu nokungqubuzana okuphansi, ngeke uhlangabezane nokwehla kwengcindezi ephansi okubangelwa amadiphozithi kumongo.Kulula ukuhlanza, okuvumela ipayipi elilodwa ukuthi lisetshenziswe ezinhlelweni eziningi.Iguquguquka futhi ilula, kulula ukuyihambisa, ukuphatha nokufaka kunamapayipi enjoloba, futhi inesilinganiso esifanayo sokuqhuma kwengcindezi.Ingakwazi ukumelana nokugoba nokudlidliza okuqhubekayo ngaphandle kokwehluleka ngenxa yokukhathala okugobayo.Ukufaka umswakama, okungeyona i-hygroscopic, ilungele ama-pigtails ekuphatheni igesi ngobuningi kanye nezinhlelo zomoya, indawo ephansi yamazolo iwukhiye.Kulula ukuphatha izinto ezinganamatheli njengezinamathiseli, itiyela, odayi, amafutha, iglue, i-latex, i-lacquer nopende.Ukungangeni kwamakhemikhali ngeke kubole noma konakale ngesikhathi sokusetshenziswa.Akukho ukuguga, okungathinteki isimo sezulu, okungagcinwa isikhathi eside ngaphandle kokuguga.Ngeke iguge ngesikhathi sokusetshenziswa.Ukumelana nokushaqeka, akuthintwa ukugoba okuqhubekayo, ukudlidliza noma ingcindezi yomthelela, futhi kungamelana nemijikelezo eshintshanayo yokubanda nokushisa

I-Polytetrafluoroethylene iyi-fluoropolymer eyenziwe ngobunjiniyela.Esinye sezici zayo eziyinhloko ukumelana kwayo okuvelele namakhemikhali;izinga lokushisa elibanzi -100F kuya ku-500F (-73C kuya ku-260C) lenza lokhu I-hose material ifanele uketshezi oluningi kanye nezimo zokushisa ezizungezile embonini;i-coefficient ye-friction ephansi kakhulu (0.05 kuya ku-0.20) inganikeza indawo enganamathele;ukumuncwa kwamanzi kwe-PTFE akukho, futhi ukuhlolwa kwe-ASTM kungaphansi kuka-0.01%.Ngaphezu kwalokho, kugunyazwe yi-FDA ukuthi isetshenziswe ekudleni nakwezemithi.Ipayipi elingaphakathi le-PTFE "PTFE" elinembobo ebushelelezi limpintsha ngokuqondile ukuze kugcinwe ukugxila kwekhwalithi ephezulu kakhulu.Yenziwe nge-polytetrafluoroethylene resin yekhwalithi ephezulu, i-304 stainless steel braided reinforcement, inani elithile lekhabhoni emnyama yengezwa kumongo we-polytetrafluoroethylene (PTFE) ukuze kuhlinzekwe indlela eqhubekayo yokufakwa kwensimbi ekugcineni, futhi idedelwe kusitimu noma izinhlelo zokusebenza zokugeleza okuphezulu. ugesi.Ukusetshenziswa okuqhubekayo: -65°~450°(-54°~ 232°) Ukusetshenziswa kwezikhawu: -100°~ 500°(-73°~ 260°) Kuhlangabezana noma kudlule izimfuneko ze-SAE 100R14.I-PTFE ihlangana ne-FDA 21 CCFR 177.1550
