Chii chinonzi PTFE?
PTFE inowanzo zivikanwa se "mambo wepurasitiki", ipolymer polima yakagadzirwa tetrafluoroethylene semonomer.Yakawanikwa naDr. Roy Plunkett muna 1938. Zvichida uchiri kunzwa usinganzwisisike nechinhu ichi, asi unoyeuka here pani isina tsvimbo yatakashandisa?Iyo isiri-tsvimbo pani yakaputirwa PTFE yekupfekedza pamusoro pepani, kuitira kuti chikafu chirege kunamatira pasi pepani, iyo inoratidza iyo PTFE yakanyanya tembiricha kuramba uye yakakwirira lubrication maitiro.Mazuvano, PTFE hupfu mbishi zvinhu zvinogadzirwa kuita zvigadzirwa zvemhando dzakasiyana, senge PTFE machubhu, PTFE yakaonda firimu, PTFE mbariro, uye PTFE mahwendefa, ayo ese anoshandiswa munzvimbo dzakasiyana.Tevere, tinokurukura mashandisirwo ePTFE machubhu mu 3D printer zvishandiso.
PTFE Inotyisa?
Musoro wekuti PTFE ine muchetura unopokana uye PTFE haina chepfu.
Asi apo PFOA (Perfluorooctanoic Acid) yakambowedzerwa kune PTFE zvinongedzo, muchetura wakaburitswa kana washandiswa pakupisa kwakanyanya.PFOA yakaoma kudzikisira kubva kwezvakatipoteredza, uye inogona kupinda muvanhu nezvimwe zvipenyu kuburikidza nezvinhu zvenyama, mweya nemvura, uye nekufamba kwenguva zvinogona kutungamirira kuderera kwehuwandu hwekubereka uye zvimwe zvirwere zvekudzivirira zvirwere.Asi ikozvino PFOA yakarambidzwa nezviremera kuti iwedzere kune PTFE zvinongedzo.Yese mishumo yedu yekuedza zvinhu zvakasvibirira inoratidzawo hapana PFOA chikamu.
Sei maprinta e3D achishandisa PTFE machubhu?
Nekukurumidza kusimudzira kweThe Times, 3D printer inokurumidza kuumba tekinoroji, inozivikanwawo seyekuwedzera kugadzira.Iyo nzira yekubatanidza kana kurapa zvinhu zviri pasi pekutonga kwekombuta kugadzira zvinhu zvine mativi matatu, kazhinji kushandisa mamorekuru emvura kana zvidimbu zvehupfu kubatanidza pamwe uye pakupedzisira kuvaka zvinhu zvakaturikidzana.Parizvino, 3D kudhinda kuumba tekinoroji inowanzosanganisirwa: kunyunguduka deposition nzira, sekushandiswa kwe thermoplastic, yakajairika crystal system metal zvinhu, kumhanya kwayo kwekuumbwa kunononoka, uye zvinhu zvinonyunguduka fluidity zviri nani;
Nekudaro, 3D maprinta ane nhoroondo yenhaka yemusoro, nyore plug!Kunyange zvazvo kukundikana kwe 3D printer yakaderera, kana yaitika, haizongokanganisa kunaka kwekudhinda, asiwo kuparadza nguva uye zvinyorwa zvekudhinda, uye kunyange kukanganisa muchina.Vanhu vazhinji vanofungidzira kuti chubhu yehuro yaipisa zvakanyanya nekuti yaive yakagadzirwa nemushonga.Nekuti mainjiniya giredhi zvinhu zvinoda yakakwira inoenderera tembiricha, izvo zvinodikanwa zvezvikamu zvakakwira zvakanyanya.Naizvozvo, iyo 3D printer inoshandisa PTFE chubhu sechubhu yekudyisa.Mazhinji maturusi anofanirwa kutakurwa kuenda kuprinta musoro munzvimbo yekunyunguduka, uye chubhu yekufambisa inofanirwa kusangana nenzvimbo inodiwa yeprinta, saka ikozvino vagadziri vazhinji vanochinja kune yakavakirwa-mukati iron fluorine dhiragoni chubhu, iron fluorine dhiragoni uye Stainless simbi. thermal conductivity yakaderera, inogona kunyatso kudzikisa tembiricha yehuro chubhu, nesimbi fluorine shato chubhu, plugging kukundikana mwero inoderedzwa zvakanyanya.Saka iyi ndiyo yakanakisa sarudzo ye3D maprinta.
Kana iwe uri mu 3D printer bhizinesi, Unogona Kuda
Izvi zvinotevera sumo yakajairika yehukuru hunhu hwePTFE machubhu:
1. Haina-adhesive: Iinert, uye zvinenge zvinhu zvose hazvina kusungirirwa kwairi.
2. Kupisa kupisa: ferroflurone ine yakanakisa kupisa kusagadzikana.General work inogona kushandiswa nguva dzose pakati pe240 ℃ uye 260 ℃.Nguva pfupi tembiricha kuramba kusvika 300 ℃ ine melting point ye327 ℃.
3. Lubrication: PTFE ine yakaderera friction coefficient.Iko friction coefficient inoshanduka kana mutoro uchitsvedza, asi kukosha kunongova pakati pe0.04 ne0.15.
4. Kuramba kwemamiriro ekunze: hapana kuchembera, uye hupenyu huri nani husina kuchembera mupurasitiki.
5. Isiri-chepfu: munzvimbo yakajairika mukati me300 ℃, ine physiological inertia uye inogona kushandiswa pakurapa uye chikafu midziyo.
Kutenga iyo chaiyo PTFE tubing haisi yekungosarudza zvakasiyana siyana zvekushandisa zvakasiyana.Zvimwe kusarudza mugadziri akavimbika.Besteflon Fluorine plastic Industry Co., Ltd. inyanzvi mukugadzirwa kwemhando yepamusoro yePTFE hoses nemachubhu kwemakore gumi nemashanu.Kana paine mibvunzo uye zvinodiwa, ndapota inzwa wakasununguka kutibvunza kune mamwe mazano ehunyanzvi.
