Teflon VS Nylon, Ndeupi Musiyano?

Kufamba-famba munyika yemapurasitiki epamusoro-soro seTeflon PTFE inogona kukukanda pakati pemakakatanwa akaita se 'nylon vs teflon' kana 'delrin vs teflon.' Heino nhungamiro yekukurumidza kukubatsira kutungamirira.

Teflon, zita rezita ratinokwereta kuna Chemours, rinomira pachena muboka. Iyo inozivikanwawo sePolytetrafluoroethylene (PTFE), chinyorwa ichi chinoratidza pachena kana zvasvika pakuramba kwemakemikari uye nekushingirira tembiricha yepamusoro. Fungidzira purasitiki isinganyungudike nyore – Teflon PTFE inodada nekunyungudika kwe327°C (620°F)! Izvi zvinoita kuti ive sarudzo yepamusoro yemabasa anoda kugadzikana mumamiriro emoto.

Asi chimbomira, pane zvimwe. Teflon haisanganisi nemakemikari. Inoramba ichipikisa, ichiita kuti ive mutambi ane simba mumunda wekugadzira, kunyanya mukugadzira zvinhu zvakadai segaskets uye mabheya. Rangarira simba rayo re dielectric re60 kV/mm? Ndicho chikonzero magetsi ekudzivirira kazhinji anosarudza Teflon.

Unogona kunzwa vanhu vachitaura nezve 'mitsipa yakaoma' yeTeflon. Pasinei nekuoma uku, coefficient yayo yakaderera yekukwesha, inofamba pakati pe 0.05-0.10, inoshandura mutambo. Iyo inotsvedza mumashandisirwo apo isiri-tsvimbo yepamusoro inofanirwa, funga nezvemapani ako asina-tsvimbo mukicheni.

Zvakadaro, kana wakarambira munharo dze 'teflon vs naironi' kana 'ptfe vs naironi', funga izvi: Chirongwa chega chega chinoda gamba rayo. Teflon inogona kunge isiri-tsvimbo uye inoshingirira kupisa, asi ingakodzera maapplication anoda adhesive bonding? Zvichida kwete.

Kusarudza purasitiki chaiyo, ingave iri kufamba nepakati 'nylon vs teflon' kana kuongorora 'delrin heat resistance,' zvinoreva kubatanidza zvinhu zvakasiyana-siyana zvezvinhu, sekusimba kwekusimba uye michina, nezvido zvepurojekiti yako.

Muchidimbu, nepo Teflon PTFE ichipenya nekupisa kwayo uye inertia yemakemikari, izvo zvinodikanwa zvepurojekiti yako zvinofanirwa kutungamira sarudzo yako yezvinhu. Zvese ndezvekufananidza zvinodiwa nezvivakwa. Sarudza zvine hungwaru, uye chirongwa chako chichakutenda!

Nylon: Iyo Paragon yeYakakwira Tensile Simba uye Kusimba

Kutanga rwendo kuburikidza nenyika yemapurasitiki kunotiunza takatarisana neNylon. Akasimba muindasitiri yemapurasitiki, kusimba kwayo uye kusimba kwakasimba, kuzununguka pakati pe75-120 MPa, inoisimudza kune imwe nzvimbo yekuzivikanwa kukuru.

Akazvarwa kubva mupfungwa dzaWallace Carothers, iyi polima yenylon haina kungomira kunze; inodaidzira. Kazhinji inowanikwa mumichina yezvikamu senge magiya, bushings, uye mabearings, inoshamisira maitiro ayo emuchina uye kupfeka kuramba nekudada. Kunyanya apo nhaurirano padzinobhururuka pakati pe 'nylon vs teflon' kana 'nylon vs delrin,' Nylon inoita mucherechedzo wayo mukugadzira mapurojekiti uye 3D kudhinda, nekuda kwekugona kwayo kuramba kusakara uye kubvaruka.

Nekudaro, gamba rega rega rine quirk. Kune Nylon, rudo rwayo kune unyoro. Kunyura kusvika 1.2% yehuremu hwayo mumvura kana yakanyudzwa kwemaawa makumi maviri nemana, iyi yakasarudzika nzvimbo inogona kumonyorora saizi yayo uye chimiro, zvichikanganisa kugadzikana kwayo kwedimensional munzvimbo dzakanyorova. Saka, patinenge tichifungisisa pamusoro pe 'izvo zvakaoma, nylon kana teflon,' zvakakosha kuziva kuti munzvimbo dzine hunyoro, Nylon inogona kupa shanduko inonyengera.

Asi, usanyengerwa zvachose ne 'ptfe vs nylon' nharo pasina kubvuma kushandiswa kwakasiyana-siyana kweNylon. Kubva kumachira kusvika pakuumbwa kwejekiseni, kuchinjika kwayo kunosimbisa kuvimbika kwayo mumaindasitiri akasiyana siyana. Mukuenzanisa, zvinhu zvakaita se 'delrin heat resistance' kana 'teflon ptfe' kugadzikana kwekemikari kunogona kutora nzvimbo yekutarisa mune mamwe maapplication, kuve nechokwadi chechinhu chimwe nechimwe, Nylon inosanganisirwa, inowana nzvimbo iyo yakasarudzika inopenya zvakanyanya.

Rangarira, kusarudza chinhu, ingave pakati penharo ye 'nylon vs teflon' kana kupfuura, inoenderana nekubatanidza zvinodiwa zvepurojekiti nesimba rezvinhu. Nylon, ine simba rayo rakasimba remuchina uye kusapfeka-kusapfeka, zvirokwazvo inokwikwidza akawanda maapplication, chero hunyoro hwayo hunoverengerwa. Rongedza sarudzo dzako zvakanaka, uye tarisa mapurojekiti ako achibudirira!

Delrin (POM): Iyo Apex yeKuoma Kwepamusoro uye Dimensional Kugadzikana

Ngatiputire kuongorora kwedu nekunyura munyika yeDelrin, zita remhando rinoruka nyaya yaro mudura re thermoplastics, chaizvo polyoxymethylene (POM).

Delrin inoratidzira humbowo hwayo nekuomarara kunoshamisa, kudzikamisa dimensional kugadzikana, uye yakaderera mwando rudo. Funga nezvazvo sechinhu ichocho chakavimbika, kunyanya kana iwe uchida chimwe chinhu chine musana wezvikamu zvako zvemakina nekuda kwekugadzikana kwayo kwepamusoro uye kusimba kwesimba rinotamba pakati pe69-79 MPa. Uku kusanganiswa kwerunako rwemuviri kunoita kuti ive mudiwa mumamiriro ezvinhu anoda musanganiswa wekunyatso uye kuoma.

Iyo 'delrin vs nylon' kuenzanisa kazhinji inomuka, kunyanya kutenderedza hukama hwavo nehunyoro. Soak Delrin kwemaawa makumi maviri nemana uye inongotora 0.25% yehunyoro, zvichiita kuti ive yakasimba kana kutamba kwechinhu chine unyoro kuri kutamba, uye kufukidza Nylon mumapurojekiti umo hunyoro mutambi akakosha.

Mumamiriro ezvinhu anoda chinhu chine hunhu hwakatsiga, kunyanya mumapurojekiti ekugadzira, Delrin anokwira. Hunyoro hwayo hwakadzikira uye kuenderana muhukuru hunoita kuti ibude pachena, kazhinji ichiiisa pachigadziko kana gakava re 'nylon vs delrin'.

Zvakakosha kucherechedza kuti kunyangwe ETFE nePTFE vese vari vemhuri yefluoropolymer, ngano dzavo dzekugadzira dzinosiyana. Kuziva kwavo nyaya dzekugadzira kunovhenekera maitiro avo ekuita uye nzira dzekushandisa.

Muchidimbu, nepo 'delrin vs teflon' kana 'nylon vs teflon' nhaurirano dzinogona kukukwezvera, rangarira: zvese ndezvekurongedza zvinhu zvakasarudzika zvezvinhu, senge Delrin's mechanical simba uye kuramba kupfeka, nezvinodiwa zvepurojekiti yako. Ndiyo kiyi yekukiyinura gonhi renyika umo mapurojekiti ako haangobudiriri; vanokunda. Saka sarudza nekuchenjera, uye mapurojekiti ako ngaarambe achibudirira nekusingaperi!

Aokai ari inyanzvi inogadzira PTFE yekupfekedza zvinhu , tinopa zvigadzirwa zvinosanganisira PTFE machira, PTFE matepi, PTFE mabhandi ekutakurisa, nezvimwe, enda kunzvimbo yedu yechigadzirwa kuti udzidze zvakawanda, kana taura nechikwata chedu , isu tinofara zvikuru kukupa rubatsiro.
