Ngaba uvile nge-PTFE imathiriyeli kunyeUmbhobho we-PTFE?Kaloku, makhe sibone ukuba singayiphendula na imibuzo ethile ngalo.
I-Polytetrafluoroethylene (i-polytetrafluoroethylene) ifinyeziwe njenge-PTFE, eyaziwa ngokuba yi "inkosi yeplastiki", kwaye igama layo lezorhwebo yiTeflon.E-China, ngenxa yokubiza igama elithi "TEFLON" likwabizwa ngokuba yiTeflon, zonke ezo ziguqulelwa kwiTeflon.I-Polytetrafluoroethylene yaziwa ngokuba "yinkosi yeeplastiki", uyise we-fluororesin Roy Planck 1936 inkampani yaseDuPont e-United States yaqala ukufunda indawo yeFreon.Baye baqokelela i-tetrafluoroethylene baza bayigcina kwiisilinda ukuze benze umfuniselo olandelayo ngosuku olulandelayo.Nangona kunjalo, xa ivalve yokukhulula uxinzelelo lwe-cylinder yavulwa ngosuku olulandelayo, akukho gesi yaphuphuma.Babecinga ukuba iyavuza, kodwa xa belinganisa isilinda, bafumanisa ukuba umbhobho awunciphi umzimba.Babona nge-cylinder kwaye bafumana umgubo omhlophe omninzi, oyipolytetrafluoroethylene.Baye bafumanisa ukuba i-polytetrafluoroethylene ineepropati ezibalaseleyo kwaye ingasetyenziswa njenge-anti melting yokutywina i-gasket yeebhombu zeathom kunye namaqokobhe.Ke ngoko, umkhosi wase-US wagcina itekhnoloji iyimfihlo ngexesha leMfazwe yesibini yeHlabathi.Kwada kwaba sekupheleni kweMfazwe Yehlabathi II apho yachithwayo yaze yafakwa kushishino ngo-1946.PTFE ithumbu elinemigca, PTFE ithumbu elityatyiweyo
I-Polytetrafluoroethylene inokubunjwa ngokunyanzeliswa okanye i-extrusion;Isenokwenziwa kwakhona ukusasazeka kwamanzi ukugquma, ukumiliselwa okanye ifayibha.I-Polytetrafluoroethylene (PTFE) isetyenziswa ngokubanzi kumashishini amandla e-athom, ukhuselo lwesizwe, i-aerospace, i-electronics, umbane, ubunjineli beekhemikhali, oomatshini, izixhobo, izixhobo, ukwakhiwa, i-textile, i-metal surface treatment, amayeza, unyango, impahla, ukutya, isinyithi kunye amashishini okunyibilikisa, njl., nto leyo eyenza ukuba ibe yimveliso engenakubuyiselwa.
I-PTFE sisishunqulelo se-polytetrafluoroethylene - ligama elide, kodwa ixesha elide kufuneka lithethe ukuba lilungile!Igama lokuthengisa le-polytetrafluoroethylene lelona gama liqhelekileyo le-polytetrafluoroethylene.
Kutheni le nto ithumbu le-polytetrafluoroethylene (PTFE) lisetyenziswa kumbhobho we-inkjet weprinta ye-3D, umbhobho wokutyisa womatshini wekofu, umbhobho wenkqubo yokupholisa amanzi kunye nenkqubo yombhobho webrake?
1) ityhubhu ye-PTFE inozinzo oluphezulu lweekhemikhali kwaye inokumelana nesenzo sazo zonke ii-acids ezinamandla, kuquka i-aqua regia, i-hydrofluoric acid, i-hydrochloric acid, i-nitric acid, i-acid evuthayo ye-sulfuric, i-asidi ephilayo, isiseko esomeleleyo, i-oxidant enamandla, i-agent yokunciphisa kunye neentlobo ezahlukeneyo zezinto eziphilayo. izinyibilikisi.Isetyenziswa kakhulu ekuhambiseni ulwelo olwahlukeneyo olurhabaxa.
2) Ingasetyenziselwa ixesha elide kuluhlu lwe-80 ℃ - + 280 ℃.Iyakwazi ukusebenza kwiqondo lokushisa elibandayo ngaphandle kwe-embrittlement kunye nokunyibilika kwiqondo lokushisa eliphezulu.
3) I-non-viscosity ebalaseleyo kunye ne-anti viscosity igqwesileyo, kwaye udonga lwangaphakathi lombhobho aluhambisani ne-colloids kunye neekhemikhali, ngoko aluyi kubumba umaleko wokungcola kumbhobho.
I-4) Ukusebenza ngokugqwesileyo kokufakelwa kombane I-Teflon yinto ephezulu kakhulu engeyopolar eneempawu ezilungileyo ze-dielectric, ukumelana okuphezulu kunye ne-dielectric engaguqukiyo malunga ne-2.0, eyona nto incinci kuzo zonke izinto zokufakelwa kombane, kunye nokutshintsha kobushushu kunye nokuphindaphinda kunempembelelo encinci kubo. .
I-5) Ukuchasana nokuguga okugqwesileyo kunye nokumelana nemitha, kunokusetyenziswa ngaphandle ixesha elide.
I-6) Ukuzinza okugqwesileyo kwe-thermal, iTeflon ine-incombustibility ebaluleke kakhulu, isalathisi sayo somda we-oksijini ingaphezulu kwe-95, inokunyibilika kuphela emlilweni, ayivelisi amaconsi, kwaye inokuthi i-carbonized kuphela.
7) Ubuthambileyo obuphezulu kunye nokumelana nokugoba.
I-8) ukumelana nomswakama: umphezulu wefilimu yeTeflon ayinamanzi kunye neoli, kwaye akulula ukungcoliswa ngesisombululo ngexesha lokusebenza kwemveliso.Ukuba kukho ungcoliseko oluncinci olunamathele, lunokususwa ngokusula okulula.Ineenzuzo zexesha elifutshane lokuphumla, ukonga iyure yomntu kunye nokuphucula ukusebenza kakuhle.
I-9) Ukuxhatshazwa kokugqoka: ukuxhatshazwa ngokugqwesileyo kokugqoka phantsi komthwalo ophezulu.Ngaphantsi komthwalo othile, ineenzuzo zokunganyangeki kunye nokungabambeleli.
Umbhobho wePolytetrafluoroethylene uneengenelo ezithile ngaphezulu kombhobho owenziwe ngerabha oqhelekileyo.
Okokuqala, i-polytetrafluoroethylene (PTFE) i-hose isebenza njengesithintelo somphunga, esingabambekiyo ngexesha elifanayo lokumelana nobushushu obuphezulu, kwaye sinokuhlangabezana neemfuno zala matshini kunye nezixhobo zokusetyenziswa kwemibhobho.
Okwesibini, i-PTFE ye-hose ene-hose ineyona michiza iphezulu yokuxhathisa kwaye ixhasa uluhlu lwe-automotive fluids irabha eqhelekileyo ayinako ukubonelela, eyona ixhaphakileyo yi-petroli blends ene-ethanol.Umbhobho werabha oqhelekileyo uya kubola xa ubekwe kolu hlobo lwepetroli kwaye ekugqibeleni uthobeke kangangokuba unokuqalisa ukuvuza okanye ukutofa isibaso, nto leyo eyingozi kakhulu.
Okwesithathu, i-hose ye-Teflon ene-hose ine-hose ephezulu kakhulu yokumelana nokushisa - enyanisweni, uluhlu lweqondo lokushisa lokusebenza oluthengiswa ngeetyhubhu ze-PTFE ngu-65 ° C ukuya + 260 ° C. Kufanelekile kakhulu ukusetyenziswa kwezi zixhobo.
Okwesine, i-Teflon tube Teflon hose inoxinzelelo oluphezulu kakhulu lokusebenza, kwakhona uqinisekisa ukuba ungayisebenzisa kuzo zonke iintlobo ze-automotive and hot rod applications.Ubungakanani be-An6 ye-2500psi, ubukhulu be-an8 ye-2000psi, kunye nezicelo ezinzima kakhulu, uxinzelelo lwayo lungaphezu kokwaneleyo.
enye?Ewe, enyanisweni - i-braided kwi-hose yethu iqinisekisa ubomi obude benkonzo kunye nembonakalo ebukhali yokufakela.Xa ukhetha intsimbi engatyiwa, inenkangeleko ebukhali kwaye ikunika ubuchwephesha bobuchwephesha bobunjineli bombhobho wokuva intonga eshushu.Inayiloni emnyama ukuba ufuna inkangeleko ethambileyo.Kodwa uyazi, inayiloni emnyama isenayo intsimbi engenasici.Sidinga nje ukugquma intsimbi engenasici ngenylon emnyama ukuze sijonge ngendlela eyahlukileyo.
Ngoku iyafumaneka - blue and red Nayiloni Braided PTFE lined hot rod fuel oil hose size an6.
Ke i-hose ye-PTFE ivakala ilungile- yintoni engalunganga ngayo?
Ngokubanzi, ityhubhu ye-PTFE inokubuyisela uninzi lweemeko zetyhubhu yerabha.Okukuphela kokungalunganga kwetyhubhu ye-PTFE kukuba ukuguquguquka kwayo akulunganga njengaleyo yetyhubhu yerabha.Nangona kunjalo, uthotho lwe-bellows ye-PTFE ityhubhu inokuguquguquka okuthile, okunokusombulula esi siphene sincinci.Kodwa kukho ezinye izinto ekufuneka uzazi.
I-1 - ye-PTFE ye-hose ene-lined, kufuneka usebenzise izixhobo ezifanelekileyo ezivela kumvelisi ofanayo ukuqinisekisa ukutywinwa okulungileyo kwizinto zokufakelwa.Ekubeni isitywina senziwe nge-ferrule endaweni yokufaka kwi-hose ye-rubber, kufuneka kuthathelwe ingqalelo ngakumbi xa usika.Ngolwazi oluthe vetshe, bona imiyalelo yethu yokuhlohla.
I-radius yokugoba ye-2-ptfe hose ingqongqo ngakumbi kuba kuya kuba lula ukukhaba ukuba idlula inkcazo.Ukufumana ulwazi oluthe kratya, bona inqaku lethu kwi-bend radius.
Akunjalo ngepayipi le-fuel intonga eshushu, kodwa ukuba uthenga ngeenxa zonke,Umbhobho we-PTFEngokuqhelekileyo ibiza kakhulu kune-rubber lined hose - ixabiso le-hot rod fuel hose lihle kakhulu, ngokuphindaphindiweyo amaxesha amaninzi ixabiso le-rubber hose, kwaye liya kuhlala ixesha elide.
