Teflon vs nylon, yini umehluko?

Ukuzulazula emhlabeni we-plastitics wokusebenza okuphezulu njengeTeflon Ptfe kungakujikijela phakathi kwezimpikiswano ezifana ne- 'nylon vs teflon ' noma 'delrin vs teflon. ' Nansi umhlahlandlela osheshayo wokukusiza ukuqondisa.

I-Teflon, igama lomkhiqizo sikweleta amakhemikhali, sivelele esixukwini. Yaziwa nangokuthi i-polytetrafluoroethylene (PTFE), lokhu okubonakalayo kukhombisa uma kukhulunywa ngokumelana kwamakhemikhali nokumelana nokushisa okuphezulu. Cabanga ngeplastiki engancibiliki kalula - I-Teflon Ptfe ngokuziqhenya inamahloni okuncibilika kuka-327 ° C (620 ° F)! Lokhu kwenza kube ukukhetha okuphezulu kwemisebenzi edinga ukuqina ezimeni zomlilo.

Kepha linda, kunokuningi. I-Teflon ayihlangane namakhemikhali. Ihlala imelana, okwenza kube ngumdlali oqinile ensimini yokukhiqiza, ikakhulukazi ekukhiqizeni izinto ezifana nama-gaskets kanye ne-bearings. Khumbula amandla ayo e-dielectric angu-60 kv / mm? Kungakho ukufakwa kukagesi kuvame ukukhetha i-teflon.

Ungezwa abantu bakhuluma nge-teflon's 'stuff tom. Ingena kwizicelo lapho indawo engeyona induna kufanele, cabanga ngamapani akho anganamathele ekhishini.

Kodwa-ke, lapho unamathela ku- 'teflon vs nylon ' noma 'ptfe vs nylon ' ukubheka lokhu: yonke iphrojekthi idinga iqhawe layo. I-Teflon ingahle ibe yi-non-stick kanye nokuqina kokushisa, kepha ingabe ihambisana nezinsiza ezidinga ukubopha okunamathelayo? Mhlawumbe akunjalo.

Ukukhetha ipulasitiki efanele, noma ngabe lokho kuhamba nge- 'nylon vs teflon ' noma ukuhlola ukumelana nokushisa 'delrin, ' kusho ukuvumelana ngezakhiwo eziyingqayizivele zezinto ezibonakalayo, njengamandla ashubile kanye nezidingo zephrojekthi yakho.

Ngase-Essence, ngenkathi i-teflon PTFE idonsa ngokumelana kwayo kokushisa kanye ne-inertia yamakhemikhali, izimfuno zakho ezithile zephrojekthi kufanele ziqondise ukukhetha kwakho okubonakalayo. Konke kumayelana nezidingo ezifanayo ngezakhiwo. Khetha ngobuhlakani, futhi iphrojekthi yakho izokubonga!

I-Nylon: i-paragon yamandla aphezulu aphezulu nokuqina

Ukuqala uhambo ngomhlaba we-plastics kusilethela ubuso nobuso ne-nylon. I-stalwart embonini yePlastics, ukuqina kwayo kanye namandla aphezulu ashubile, ukuquleka phakathi kuka-75-120 Mpa, akuphakamise endaweni yokuqashelwa okukhulu.

Uzalwe engqondweni kaWallace Carothers, le nylon polymer ayiveli nje; Kuyamemeza. Imvamisa etholakala ezingxenyeni zemishini njengegiya, ama-bushings, kanye namabhele, ifaka izakhiwo zayo zemishini futhi igqoke ukumelana nokuziqhenya. Ikakhulu lapho izingxoxo zihamba phakathi kwe- 'nylon vs teflon ' noma 'nylon vs delrin, ' i-nylon yenza umaki wayo kumaphrojekthi wemishini kanye nokuphrinta kwe-3D, ngenxa yekhono lawo lokumelana nokudabuka.

Kodwa-ke, wonke amaqhawe ane-quirk. Nge-nylon, uthando lwayo umswakama. Ukutholwa kuze kufike ku-1.2% wesisindo sayo emanzini lapho ifakwe emanzini amahora angama-24, le mpahla eyingqayizivele ingasonta usayizi wayo nokwakheka, inomthelela wokuqina kwayo okubunjiwe. Ngakho-ke, ngenkathi sizindla nge- 'okunzima, i-nylon noma i-teflon, ' kungcono ukuqaphela ukuthi ezindaweni ezithambekele zomswakama, i-nylon ingaletha ukuguquguquka okukhohlisayo.

Kodwa-ke, ungadukiswa ngokuphelele yi- 'PTFE vs vs nylon ' ngaphandle kokuvuma ukuguquguquka okuhle kwe-nylon. Ukusuka ezindwangu kuya ekubumbeni umjovo, ukuzivumelanisa nezimo kwayo kusekela ukuthembeka kwayo kuyo yonke imboni ehlukahlukene. Uma kuqhathaniswa, izici ezinjengokuthanda ukumelana nokushisa okushisa

Khumbula, ukhethe okuqukethwe, noma ngabe kunesifo se- 'nylon vs teflon ' 'ngedlula, ujikeleze ukuvumelanisa okufunwa kwephrojekthi ngamandla ezibonakalayo. I-Nylon, ngamandla ayo asezingeni eliphakemeyo kanye nemvelo evikelekile, ngokuqinisekile ompetha izicelo eziningi, inyuke ubudlelwane bayo bokuswakama. Yenza kahle izinketho zakho, bese ubuka amaphrojekthi akho echuma!

I-Delrin (POM): I-apex yokuqina okuphezulu nokuqina kobukhulu

Masisonge ukuhlola kwethu ngokungena ezweni laseDelrin, igama lomkhiqizo liluka udaba lwalo esizindeni se-thermoplastics, ngokuqondile i-polyoxymethylene (POM).

I-Delrin iphatha iziqinisekiso zayo ngokuqina okuphawulekayo, ukuqina okuhlaba umxhwele, kanye nesilinganiso sothando lomswakama oluphansi. Cabanga ngakho njengento ethembekile, ikakhulukazi lapho udinga okuthile okunomgogodla wezingxenye zakho zemishini ngenxa yokuqina kwayo okuphezulu okuphezulu kanye namandla aphezulu adansa phakathi kuka-69-79 MPA. Lokhu kuhlanganiswa kwe-charm engokomzimba kwenza kube mnandi ezimweni ezidinga ukuxubana kokunemba nokuqina.

Ukuqhathanisa 'Delrin vs nylon ' kuvame ukuvela, ikakhulukazi ngobuhlobo babo nomswakama. Chofoza Delrin amahora angama-24 futhi uthatha kuphela u-0,25% womswakama, okwenza kube yi-stalwart lapho umdanso wokwaziswa lapho umdanso udlala khona, futhi emboza i-nylon kumaphrojekthi lapho umswakama umdlali obalulekile.

Kulezi zimo ezidinga okufunwa ngumlingiswa oqinile, ikakhulukazi kumaphrojekthi wemishini, izinyathelo ze-delrin. Ukubumbana kwalo okuphansi komswakama nokungaguquguquki ngokwezilinganiso kukwenza ukuthi kuvezwe, kuvame ukukubeka esisekelweni lapho 'nylon vs delrin ' reformation surfaces.

Kuhle ukuqaphela ukuthi yize i-etfe ne-PTFE yobabili ingeyomndeni we-fluoropolymer, izindaba zabo zokukhiqiza ziyahlukahluka. Ulwazi ngezindaba zabo zokukhiqiza zikhanyisela izimfanelo zazo zokusebenza kanye nezinhlobo zohlelo lokusebenza.

Kafushane nje, ngenkathi 'delrin vs teflon ' izingxoxo '' nylon vs teflon 'zingakugwema, khumbula ukuthi: Kuyisihluthulelo sokuvula umnyango ezweni lapho amaphrojekthi akho angaphumelela khona nje; bayadlula. Ngakho-ke khetha ngobuhlakani, futhi kwangathi amaphrojekthi akho azochuma kuze kube phakade!

Aokai a Umakhi ochwepheshe wezinto zokwenziwa kwe-PTFE , sinikezela ngemikhiqizo kubandakanya Izindwangu ze-PTFE, Amateyipu we-PTFE, Amabhande we-PTFE ahambisa, njll., Iya esikhungweni sethu somkhiqizo ukuze ufunde kabanzi, noma Thintana nethimba lethu , sijabule kakhulu ukukunikeza usizo.
