I-Teflon VS Inayiloni, Uyini Umehluko?

Ukuzulazula emhlabeni wamapulasitiki asebenza kahle kakhulu njenge-Teflon PTFE kungase kukuphonse phakathi kwezimpikiswano ezifana nokuthi 'inayiloni vs teflon' noma 'delrin vs teflon.' Nansi inkomba esheshayo yokukusiza ukuthi udlule.

I-Teflon, igama lomkhiqizo esilikweleta iChemours, igqamile esixukwini. Eyaziwa nangokuthi i-Polytetrafluoroethylene (PTFE), le nto ibonakala uma kuziwa ekuphikisweni kwamakhemikhali kanye nokumelana namazinga okushisa aphezulu. Cabanga ngepulasitiki engancibiliki kalula - I-Teflon PTFE ngokuziqhenya izidla ngephoyinti lokuncibilika elingu-327°C (620°F)! Lokhu kwenza kube ukukhetha okuphezulu kwemisebenzi efuna uzinzo ezimeni ezishisayo.

Kodwa linda, kukhona okwengeziwe. I-Teflon ayihlangani namakhemikhali. Ihlala imelana, iyenze ibe ngumdlali onamandla emkhakheni wokukhiqiza, ikakhulukazi ekukhiqizeni izinto ezifana nama-gaskets nama-bearings. Khumbula amandla ayo e-dielectric angu-60 kV/mm? Yingakho ukufakwa kukagesi kuvame ukukhetha iTeflon.

Ungase uzwe abantu bekhuluma 'ngentamo eqinile' yeTeflon Naphezu kwalokho kuqina, i-coefficient yayo ephansi yokungqubuzana, ehamba phakathi kuka-0.05-0.10, ishintsha umdlalo. Islayida ibe izinhlelo zokusebenza lapho indawo enganamathele iyimfuneko, cabanga ngamapani akho anganamathiki ekhishini.

Nokho, uma ubambekile engxoxweni 'i-teflon vs inayiloni' noma 'ptfe vs inayiloni' cabanga ngalokhu: Yonke iphrojekthi idinga iqhawe layo. I-Teflon ingase inganamatheli futhi imelane nokushisa, kodwa ingabe ingafanelana nezinhlelo zokusebenza ezidinga ukunamathela okunamathelayo? Mhlawumbe akunjalo.

Ukukhetha ipulasitiki efanele, noma ngabe lokho wukuzula 'inayiloni vs teflon' noma ukuhlola 'ukumelana nokushisa kwe-delrin,' kusho ukuqondanisa izici eziyingqayizivele zento esebenzayo, njengamandla aqinile kanye nezakhiwo zokukhanda, nezidingo zephrojekthi yakho.

Empeleni, ngenkathi i-Teflon PTFE igqama ngokumelana nokushisa kwayo kanye ne-chemical inertia, izimfuno eziqondile zephrojekthi yakho kufanele ziqondise ukukhetha kwakho okubalulekile. Konke kumayelana nokufanisa izidingo nezakhiwo. Khetha ngobuhlakani, futhi iphrojekthi yakho izokubonga!

Inayiloni: I-Paragon Yamandla Amandla Aqinile Nokuqina

Ukuqalisa uhambo lokunqamula umhlaba wepulasitiki kusiletha ubuso nobuso ngeNyiloni. Isazi esiqinile embonini yepulasitiki, ukuqina kwayo namandla aqinile aqinile, anyakazayo phakathi kuka-75-120 MPa, kuyiphakamisela endaweni yokuqashelwa okukhulu.

Izalwe emqondweni kaWallace Carothers, le polima enayiloni ayivele igqame; kumemeza ngempela. Ivamise ukutholakala ezingxenyeni eziwumshini njengamagiya, ama-bushings, nama-bearings, ibukisa ngezakhiwo zayo zomshini futhi igqoke ukumelana ngokuziqhenya. Ikakhulukazi uma izingxoxo zishintsha phakathi 'inayiloni vs teflon' noma 'inayiloni vs delrin,' Inayiloni yenza uphawu layo kumaphrojekthi womshini nokuphrinta kwe-3D, ngenxa yekhono layo lokumelana nokuguga.

Nokho, wonke amaqhawe ane-quirk. NgeNyiloni, wuthando lwayo lokuswakama. Imunca kufikela ku-1.2% wesisindo sayo emanzini lapho icwiliswe amahora angu-24, le ndawo eyingqayizivele ingase isonte usayizi nokuma kwayo, kube nomthelela ekuzinzeni kwayo kobukhulu ezindaweni ezimanzi. Ngakho-ke, ngenkathi sizindla 'okunzima kakhudlwana, inayiloni noma i-teflon,' kubalulekile ukuqaphela ukuthi ezindaweni ezithandwa umswakama, inayiloni ingase yethule okuguquguqukayo okukhohlisayo.

Nokho, ungathonywa ngokuphelele izingxabano 'ptfe vs inayiloni' ngaphandle kokuvuma ukuguquguquka okuhle kweNyiloni. Ukusuka ezindwangu kuya ekubunjweni komjovo, ukuzivumelanisa nezimo kusekela ukwethembeka kwayo kuzo zonke izimboni ezihlukahlukene. Uma kuqhathaniswa, izici ezifana 'nokumelana nokushisa kwe-delrin' noma 'i-teflon ptfe' ukuzinza kwamakhemikhali kungase kubonakale kwezinye izinhlelo zokusebenza, kuqinisekiswe ukuthi impahla ngayinye, kufakwe inayiloni, ithola indawo lapho izici zayo ezihlukile zikhanya kakhulu.

Khumbula, ukukhetha into ethile, kungakhathaliseki ukuthi phakathi kwenkulumo-mpikiswano 'inayiloni ne-teflon' noma ngale kwalokho, kuhlanganisa nokuqondanisa izimfuno zephrojekthi namandla wezinto ezibonakalayo. Inayiloni, enamandla ayo okusebenza aqinile kanye nemvelo engagugi, ngokuqinisekile inqoba izicelo eziningi, inqobo nje uma kubalwa ukuhambisana kwayo komswakama. Yenza izinqumo zakho kahle, futhi ubuke amaphrojekthi akho echuma!

I-Delrin (POM): I-Apex Yokuqina Okuphezulu Nokuzinza Kwe-Dimensional

Ake sigoqe ukuhlola kwethu ngokungena emhlabeni we-Delrin, igama lomkhiqizo eleluka indaba yalo esizindeni se-thermoplastics, precisely polyoxymethylene (POM).

I-Delrin ibukisa izifakazelo zayo ngokuqina okuphawulekayo, ukuzinza kwe-dimensional okuhlaba umxhwele, kanye nezinga eliphansi lokuthanda umswakama. Kucabange njengaleyo nto ethembekile, ikakhulukazi uma udinga okuthile okunomgogodla wezingxenye zakho eziwumshini ngenxa yokuqina kwayo kobukhulu obuphezulu namandla aqinile adansa phakathi kuka-69-79 MPa. Le ngxube yentelezi ebonakalayo iyenza ithandeke ezimeni ezidinga ingxube yokunemba kanye nokuqina.

Ukuqhathanisa 'delrin vs inayiloni' kuvame ukuvela, ikakhulukazi mayelana nobudlelwano babo nomswakama. Gcoba i-Delrin amahora angu-24 futhi imunca kuphela u-0.25% womswakama, okuyenza iqine uma kudlalwa umdanso wento enokuswakama, futhi kusibekele inayiloni kumaphrojekthi lapho umswakama ungumdlali obalulekile.

Ezimeni ezidinga okokusebenza okunomlingisi ozinzile, ikakhulukazi kumaphrojekthi wokwenza imishini, u-Delrin uyakhuphuka. Ukuhambisana komswakama wayo ophansi kanye nokungaguquguquki kobukhulu kuyenza igqame, ivamise ukuyibeka phezu kwesisekelo lapho impikiswano 'inayiloni vs delrin' iba.

Kuhle ukuqaphela ukuthi nakuba i-ETFE ne-PTFE zombili zingezomndeni we-fluoropolymer, izinganekwane zawo zokukhiqiza ziyahluka. Ulwazi lwezindaba zabo zokukhiqiza lukhanyisela izici zabo zokusebenza nezindlela zokusebenzisa.

Kafushane, kuyilapho izingxoxo 'delrin vs teflon' noma 'inayiloni vs teflon' zingase zikunyakazise, ​​khumbula: konke kumayelana nokuqondanisa izici eziyingqayizivele zempahla, njengamandla emishini kaDelrin nokumelana nokugqokwa, nezidingo zephrojekthi yakho. Kuyisihluthulelo sokuvula umnyango emhlabeni lapho amaphrojekthi akho engaphumeleli nje; bayaphumelela. Ngakho-ke khetha ngokuhlakanipha, futhi kwangathi amaphrojekthi akho angaphumelela kuze kube phakade!

U-Aokai a umkhiqizi ochwepheshe wezinto zokuhlanganisa ze-PTFE , sihlinzeka ngemikhiqizo ehlanganisa Izindwangu ze-PTFE, PTFE amateyipu, Amabhande okuthutha e-PTFE, njll., iya esikhungweni sethu somkhiqizo ukuze ufunde kabanzi, noma xhumana nethimba lethu , sijabule kakhulu ukukunikeza usizo.
