ITeflon VS Inayiloni,Nguwuphi Umahluko?

Ukuzulazula kwihlabathi leeplastiki ezisebenza kakhulu njengeTeflon PTFE inokukuphosa embindini weengxoxo ezinje 'nayiloni vs teflon' okanye 'delrin vs teflon.' Nasi isikhokelo esikhawulezayo sokukunceda ukuba uhambe.

I-Teflon, igama lophawu esilityala iChemours, ligqame phakathi kwesihlwele. Eyaziwa nangokuthi i-Polytetrafluoroethylene (PTFE), le nto ibonisa xa ifika ekuxhathiseni kweekhemikhali kunye nokumelana nokushisa okuphezulu. Yiba nomfanekiso-ngqondweni weplastiki enganyibiliki lula – iTeflon PTFE iqhayisa ngeqondo lokunyibilika lama-327°C (620°F)! Oku kuyenza ibe yeyona nto iphambili yokukhetha imisebenzi efuna uzinzo kwiimeko ezinomlilo.

Kodwa linda, kukho okungakumbi. ITeflon ayidibani neekhemikhali. Ihlala ixhathisa, iyenza ibe ngumdlali onamandla kwintsimi yokuvelisa, ngokukodwa ekuveliseni izinto ezifana neegaskets kunye neebheringi. Khumbula amandla ayo edielectric angama-60 kV/mm? Yingakho ukugquma kombane kudla ngokukhetha iTeflon.

Unokubava abantu bethetha 'ngentamo elukhuni' yeTeflon. Ngaphandle kobo kuqina, i-coefficient yayo ephantsi ye-friction, ehamba phakathi kwe-0.05-0.10, i-game-changer. Ityibilika kwizicelo apho indawo engabambekiyo iyimfuneko, cinga ngeepani zakho ezinganamatheli ekhitshini.

Nangona kunjalo, xa ubambekile kwiingxoxo 'zeteflon vs nayiloni' okanye 'ptfe vs nayiloni' mpikiswano, qwalasela oku: Iprojekthi nganye idinga iqhawe layo. I-Teflon isenokunganamatheli kwaye ikwazi ukumelana nobushushu, kodwa ngaba iya kulungela usetyenziso olufuna ukuncamathela okuncamathelayo? Mhlawumbi akunjalo.

Ukukhetha iplastiki efanelekileyo, nokuba kukukhangela 'inayiloni vs teflon' okanye ukuhlola 'ukumelana nobushushu bedelrin,' kuthetha ukulungelelanisa iimpawu ezizodwa zemathiriyeli, njengamandla okuqina kunye neempawu zoomatshini, kunye neemfuno zeprojekthi yakho.

Ngokwenyani, ngelixa iTeflon PTFE ikhazimla ngokuxhathisa ubushushu kunye ne-inertia yemichiza, iimfuno ezikhethekileyo zeprojekthi yakho kufuneka zikhokele ukhetho lwakho lwemathiriyeli. Imalunga nokuthelekisa iimfuno ezineempawu. Khetha ngobuchule, kwaye iprojekthi yakho iya kukubulela!

Inayiloni: IParagon yaMandla oMbane oPhezulu kunye noKuhlala ixesha elide

Ukuqalisa uhambo kwihlabathi leplastiki kusizisa ubuso ngobuso kunye neNylon. I-stalwart kushishino lweplastiki, ukuqina kwayo kunye nokomelela okuphezulu, ukugungqa phakathi kwe-75-120 MPa, kuyiphakamisela kwindawo yokwazisa okukhulu.

Izalwe ngengqondo kaWallace Carothers, le polima yenayiloni ayivele igqame; iyakhwaza. Ihlala ifumaneka kwiindawo zoomatshini njengeegiya, iibhutsi, kunye neebheringi, ibonakalisa iimpawu zayo zomatshini kwaye inxibe ukuxhathisa ngokuzingca. Ngokukodwa xa iingxoxo zijika phakathi 'inayiloni vs teflon' okanye 'inayiloni vs delrin,' Inayiloni yenza uphawu lwayo kwiiprojekthi zomatshini kunye noshicilelo lwe-3D, ngenxa yokukwazi kwayo ukumelana nokuguga.

Nangona kunjalo, onke amaqhawe ane-quirk. KwiNyiloni, luthando lwayo lokufuma. Ukufunxa ukuya kuthi ga kwi-1.2% yobunzima bayo emanzini xa imanziswe iiyure ezingama-24, le propati yahlukileyo isenokuthi ijije ubungakanani kunye nokumila kwayo, ibe nefuthe kuzinzo kwidimensional yayo kwiindawo ezifumileyo. Ke, ngelixa sicingisisa malunga 'nento enzima ngakumbi, inayiloni okanye iteflon,' kubalulekile ukuqaphela ukuba kwindawo ezinobumanzi, inayiloni inokubonisa ukuguquguquka okukhohlisayo.

Nangona kunjalo, ungagungqiswa ngokupheleleyo ziingxoxo 'ze-ptfe vs inayiloni' ngaphandle kokuvuma ukuguquguquka okugqwesileyo kweNylon. Ukusuka kwilaphu elilukiweyo ukuya ekubunjweni kwesitofu, ukuziqhelanisa nokuziqhelanisa nokuthembeka kwayo kumashishini awohlukeneyo. Xa kuthelekiswa, imiba efana 'i-delrin ukumelana nobushushu' okanye 'teflon ptfe' uzinzo lwekhemikhali inokuthatha indawo ebonakalayo kwezinye izicelo, iqinisekisa imathiriyeli nganye, iNayiloni ebandakanyiweyo, ifumana indawo apho iimpawu zayo ezizodwa zibengezela ngokuqaqambileyo.

Khumbula, ukukhetha imathiriyeli, nokuba phakathi kwengxoxo 'inayiloni vs teflon' okanye ngaphaya, ijikeleza ukulungelelanisa iimfuno zeprojekthi namandla ezinto eziphathekayo. Inayiloni, enamandla omatshini owomeleleyo kunye nendalo ekwazi ukumelana nokunxitywa, ngokuqinisekileyo iyazimela usetyenziso oluninzi, ngaphandle kokuba ukufuma kwayo kubalwe. Lungisa ukhetho lwakho kakuhle, kwaye ubukele iiprojekthi zakho ziphumelela!

I-Delrin (i-POM): I-Apex ye-High Stiffness kunye ne-Dimensional Stability

Masisonge uphononongo lwethu ngokuntywila kwihlabathi laseDelrin, igama lebrendi eleluka ibali lalo kwindawo ye-thermoplastics, kanye i-poyoxymethylene (POM).

I-Delrin ipapasha iziqinisekiso zayo ngokuqina okuphawulekayo, uzinzo olumangalisayo, kunye nesantya esiphantsi sothando lokufuma. Cinga njengento ethembekileyo, ngakumbi xa ufuna into enomqolo kumacandelo akho omatshini ngenxa yokuzinza kwayo okuphezulu kunye nokuqina kokuqina okudanisa phakathi kwe-69-79 MPa. Lo mxube womtsalane womzimba uwenza ube yintandane kwiimeko ezifuna umxube wokuchaneka kunye nobungqongqo.

Uthelekiso 'delrin vs inayiloni' luhlala luvela, ngakumbi malunga nobudlelwane babo nokufuma. Soak iDelrin kwiiyure ezingama-24 kwaye ifunxa kuphela i-0.25% yokufuma, iyenza ibe yi-stalwart xa umdaniso wezinto eziphathekayo kunye nomswakama udlalwa, kwaye ugqume iNylon kwiiprojekthi apho ukufuma ngumdlali obalulekileyo.

Kwiimeko ezifuna imathiriyeli enophawu oluzinzileyo, ngakumbi kwiiprojekthi zoomatshini, uDelrin uyanyuka. Ukufuma kwayo okuphantsi kunye nokungaguquguquki kwimilinganiselo kuyenza igqame, isoloko iyibeka phezu kwesiseko xa 'inayiloni vs delrin' ikwingxoxo-mpikiswano.

Kubalulekile ukuqaphela ukuba nangona i-ETFE kunye ne-PTFE zombini bezizezosapho lwe-fluoropolymer, amabali abo okuvelisa ahlukile. Ulwazi lwamabali abo emveliso lukhanyisela iimpawu zabo zokusebenza ezahlukeneyo kunye neendlela zokusebenzisa.

Ngamafutshane, ngelixa 'delrin vs teflon' okanye 'nylon vs teflon' iingxoxo zingakushukumisa, khumbula: konke malunga nokulungelelanisa iimpawu ezizodwa zezinto eziphathekayo, njengamandla omatshini kaDelrin kunye nokuchasana nokunxiba, kunye neemfuno zeprojekthi yakho. Sisitshixo sokuvula umnyango wehlabathi apho iiprojekthi zakho zingaphumeleli nje; bayagqwesa. Ke khetha ngobulumko, kwaye ngamana iiprojekthi zakho zingakhula ngonaphakade!
