Yintoni ipayipi ye-ptfe | BESTEFLON

Ngaba ukhe weva ngezinto ze-PTFE kunyeUmbhobho we-PTFEMakhe sibone ukuba singaphendula na imibuzo ethile ngayo.

I-Polytetrafluoroethylene (i-polytetrafluoroethylene) ifinyeziwe njenge-PTFE, eyaziwa ngokuba yi-"plastic king", kwaye igama layo lezorhwebo yi-Teflon. E-China, ngenxa yendlela ebizwa ngayo, igama elithi "TEFLON" likwaziwa ngokuba yi-Teflon, zonke eziguqulelwa kwi-Teflon. I-Polytetrafluoroethylene yaziwa ngokuba yi-"king of plastics", uyise we-fluororesin Roy Planck 1936 DuPont company e-United States yaqala ukufunda izinto ezithatha indawo ye-Freon. Baqokelela i-tetrafluoroethylene baza bayigcina kwiisilinda ukuze bayenze uvavanyo olulandelayo ngosuku olulandelayo. Nangona kunjalo, xa i-valve yokunciphisa uxinzelelo lwesilinda yavulwa ngosuku olulandelayo, akukho gesi yaphuma. Babecinga ukuba yayivuza, kodwa xa belinganisa isilinda, bafumanisa ukuba isilinda ayizange yehle ubunzima. Babona ngesilinda baza bafumana umgubo omhlophe omninzi, oyi-polytetrafluoroethylene. Bafumanise ukuba i-polytetrafluoroethylene ineempawu ezintle kwaye ingasetyenziswa njenge-anti melting sealing gasket kwiibhombu ze-athomu kunye neegobolondo. Ke ngoko, umkhosi wase-US wagcina itekhnoloji iyimfihlo ngexesha leMfazwe Yehlabathi yesiBini. Kwakungekho de kwaphela iMfazwe Yehlabathi yesiBini apho yasuswa khona kuluhlu lweendawo zoshishino yaza yaphuhliswa ngo-1946. Uphendlo oluNxulumeneyo:Umbhobho ofakwe i-PTFE, Umbhobho we-PTFE ogobileyo

I-Polytetrafluoroethylene inokwenziwa ngokucinezela okanye ngokukhupha; inokwenziwa ibe kukusasazwa kwamanzi ukuze kugqunywe, kufakwe okanye kufakwe ifayibha. I-Polytetrafluoroethylene (PTFE) isetyenziswa kakhulu kumashishini amandla e-athomu, ukhuselo lwesizwe, i-aerospace, i-electronics, umbane, ubunjineli beekhemikhali, oomatshini, izixhobo, izixhobo, ulwakhiwo, ilaphu, unyango lomphezulu wesinyithi, amayeza, ezonyango, ilaphu, ukutya, isinyithi kunye namashishini okunyibilikisa isinyithi, njl.njl., nto leyo eyenza ukuba ibe yimveliso engenakutshintshwa.

I-PTFE sisifinyezo se-polytetrafluoroethylene - ligama elide, kodwa elithi long kufuneka lithethe ukuba lilungile! Igama lophawu lwentengiso le-polytetrafluoroethylene lelona gama liqhelekileyo le-polytetrafluoroethylene.

Kutheni le nto ipayipi ye-polytetrafluoroethylene (PTFE) isetyenziswa kumbhobho we-inkjet weprinta ye-3D, umbhobho wokondla womatshini wekofu, umbhobho wenkqubo yokupholisa amanzi kunye nenkqubo yombhobho weebhuleki?

1) Ityhubhu ye-PTFE inozinzo oluphezulu lweekhemikhali kwaye inokumelana nentshukumo yazo zonke ii-asidi ezinamandla, kubandakanya i-aqua regia, i-hydrofluoric acid, i-hydrochloric acid egxininisiweyo, i-nitric acid, i-fuming sulfuric acid, i-organic acid, isiseko esomeleleyo, i-oxidant enamandla, i-reducing agent kunye nezinye izinyibilikisi ze-organic. Isetyenziswa kakhulu ekuhambiseni ulwelo olunzima oluhlukeneyo.

2) Ingasetyenziswa ixesha elide kumgama we -80 ℃ - + 280 ℃. Ingasebenza kubushushu obubandayo ngaphandle kokuqhekeka nokunyibilika kubushushu obuphezulu.

3) Umgangatho obalaseleyo we-non viscosity kunye ne-anti viscosity ulungile kakhulu, kwaye udonga lwangaphakathi lombhobho alunamatheli kwi-colloids kunye neekhemikhali, ngoko ke aluyi kwenza umaleko wokungcola kumbhobho.

4) Ukusebenza kakuhle kakhulu kokugquma umbane I-Teflon yinto engeyo-polar kakhulu eneempawu ezilungileyo ze-dielectric, ukumelana okuphezulu kunye ne-dielectric constant emalunga ne-2.0, eyona nto incinci kuzo zonke izixhobo zokugquma umbane, kwaye utshintsho lobushushu kunye nokuphindaphinda alunampembelelo ingako kuzo.

5) Ukumelana nokwaluphala okugqwesileyo kunye nokumelana nemitha, kungasetyenziswa ngaphandle ixesha elide.

6) Uzinzo oluhle kakhulu kubushushu, iTeflon inomqobo wokungatshi, isalathisi sayo somda weoksijini singaphezulu kwama-95, inokunyibilika kuphela elangatyeni, ayivelisi amathontsi, kwaye inokunyibilikiswa kuphela kwikhabhoni.

7) Ukuthamba okuphezulu kunye nokumelana nokugoba.

8) Ukumelana nokufuma: umphezulu wefilimu yeTeflon awunamanzi okanye ioyile, kwaye akulula ukungcoliswa ngesicombululo ngexesha lokusebenza kwemveliso. Ukuba kukho ukungcola okuncinci okunamatheleyo, kunokususwa ngokusula nje. Inezibonelelo zokungasebenzi ixesha elifutshane, ukonga iiyure zomsebenzi kunye nokuphucula ukusebenza kakuhle.

9) Ukumelana nokuguguleka: ukumelana nokuguguleka okugqwesileyo xa kuthwalwa kakhulu. Phantsi komthwalo othile, ineengenelo zokungaguguleki nokunganamatheli.

Ipayipi yePolytetrafluoroethylene ineengenelo ezithile kunepayipi eqhelekileyo enerabha.

Okokuqala, ipayipi ye-polytetrafluoroethylene (PTFE) isebenza njengomqobo womphunga, onganamatheliyo ngaxeshanye wokumelana nobushushu obuphezulu, kwaye inokuhlangabezana neemfuno zezi matshini kunye nezixhobo zokusebenzisa imibhobho.

Okwesibini, ipayipi yePTFE inokumelana okuphezulu kweekhemikhali kwaye ixhasa uluhlu lweziselo zeemoto ezingenakubonelelwa ngerabha eqhelekileyo, eyona ixhaphakileyo yimixube yepetroli equlethe i-ethanol. Ipayipi yerabha eqhelekileyo iya kubola xa ivezwa kolu hlobo lwepetroli kwaye ekugqibeleni yonakale kangangokuba inokuqala ukuvuza okanye ukufaka ipetroli, nto leyo eyingozi kakhulu.

Okwesithathu, ipayipi eneTeflon inokumelana nobushushu obuphezulu kakhulu - eneneni, ubushushu obusebenzayo bepayipi ethengiswa ngeetyhubhu zePTFE buphakathi kwama-65° C ukuya kuma-260° C. Ifanelekile kakhulu ukusetyenziswa kwezi zixhobo.

Okwesine, ityhubhu yeTeflon ipayipi yeTeflon inoxinzelelo oluphezulu kakhulu lokusebenza, iqinisekisa kwakhona ukuba ungayisebenzisa kuzo zonke iintlobo zezicelo zeemoto kunye neentonga ezishushu. Ubungakanani be-An6 kwi-2500psi, ubungakanani be-an8 kwi-2000psi, nokuba zezona zicelo zinzima kakhulu, uxinzelelo lwayo lungaphezulu kolwaneleyo.

enye? Ewe, eneneni - ukuluka kwipayipi yethu kuqinisekisa ubomi benkonzo ende kunye nenkangeleko ebukhali yokufakelwa. Xa ukhetha intsimbi engagqwaliyo, inenkangeleko ebukhali kwaye ikunika uvakalelo lwe-hot rod yobungcali bobunjineli bepayipi. I-nylon emnyama ukuba ufuna inkangeleko ethambileyo. Kodwa uyazi, i-nylon emnyama isenayo i-lining yentsimbi engagqwaliyo. Sidinga nje ukugquma intsimbi engagqwaliyo nge-nylon emnyama ukuze sifumane inkangeleko eyahlukileyo.

Ngoku iyafumaneka - ipayipi ye-PTFE enombala oluhlaza okwesibhakabhaka nobomvu ene-nylon braided enobukhulu be-an6.

Ngoko ke ipayipi ye-PTFE ivakala kakuhle - yintoni ingxaki ngayo?

Ngokubanzi, ityhubhu yePTFE ingathatha indawo yeemeko ezininzi zeetyhubhu zerabha. Eyona nto imbi ngetyhubhu yePTFE kukuba ukuguquguquka kwayo akulunganga njengokwetyhubhu zerabha. Nangona kunjalo, uthotho lweetyhubhu zePTFE lunokuguquguquka okuthile, okunokusombulula esi siphene sincinci. Kodwa kukho izinto ezithile ekufuneka uzazi.

1 - kwipayipi efakwe i-PTFE, kufuneka usebenzise izixhobo ezifanelekileyo ezivela kumenzi ofanayo ukuqinisekisa ukuvalwa kakuhle kwezixhobo. Ekubeni itywina lenziwe nge-ferrule endaweni ye-insert kwipayipi yerabha, kufuneka kuthathelwe ingqalelo ngakumbi xa kusikwa. Ukuze ufumane ulwazi oluthe kratya, bona imiyalelo yethu yokufaka.

Irediyasi yokugoba yepayipi ye-2-ptfe ingqongqo ngakumbi kuba kuya kuba lula ukuyigoba ukuba idlula imiqathango. Ukuze ufumane ulwazi oluthe kratya, jonga inqaku lethu malunga nerediyasi yokugoba.

Akunjalo ngepayipi yepetroli ye-hot rod, kodwa ukuba ukhangela indawo,Umbhobho we-PTFEIdla ngokuba ibiza kakhulu kunepayipi yerabha efakwe irabha - ixabiso lepayipi yepetroli ye-hot rod lihle kakhulu, lidla ngokuliphinda kaninzi ixabiso lepayipi yerabha, kwaye liya kuhlala ixesha elide.
