Libakeng tse ngata, PEEK e atisa ho sebelisoa ho finyella thepa e tšoanang le e fanoang ke litšepe le lisebelisoa tlas'a maemo a thata.Mohlala, lits'ebetso tse ngata li hloka ho hanyetsa khatello ea nako e telele, ho hanyetsa ho roala, matla a thata le ts'ebetso e phahameng, le ho hanyetsa kutu.Ka indasteri ea oli le khase, melemo e ka bang teng ea thepa ea PEEK e ka sebelisoa.
Ha re ithute ka ts'ebetso le ts'ebeliso ea lisebelisoa tsa peek.
Le leng la mabaka a ts'ebeliso e atileng ea PEEK lits'ebetsong tsa boenjiniere ke ho ba teng ha likhetho tse ngata le maemo a ts'ebetso, e leng machining, masela a kopantsoeng a filament, khatiso ea 3D, le ho bopa ente, ho etsa li-geometri tse lakatsehang tikolohong ea manyolo le e nang le metsi.
Lisebelisoa tsa PEEK li fumaneha ka mokhoa oa molamu, valve e hatelitsoeng ea poleiti, foromo ea filament le foromo ea pellet, e ka sebelisoang bakeng sa machining a CNC, khatiso ea 3D le ho bōpa ente ka ho latellana.
1. PEEK CNC tshebetso
CNC (taolo ea linomoro tsa komporo) e na le mefuta e fapaneng ea ho sila ka li-multi-axis, ho fetola le ho ntša motlakase (EDM) ho fumana geometry ea ho qetela e lakatsehang.Monyetla o ka sehloohong oa mechine ena ke bokhoni ba ho laola mochine ka balaoli ba tsoetseng pele ka likhoutu tse hlahisoang ke k'homphieutha ho etsa machining a phahameng a nepahetseng a mosebetsi o batlang.
CNC machining e fana ka maemo a ho theha li-geometri tse rarahaneng ka thepa e fapaneng, ho tloha ho polasetiki ho ea ho tšepe, ha e ntse e kopana le meeli e hlokahalang ea mamello ea geometri.Lisebelisoa tsa PEEK li ka sebetsoa ka mokhoa o rarahaneng oa li-geometric, hape li ka sebetsoa ka likarolo tsa PEEK tsa boemo ba bongaka le tsa boemo ba indasteri.CNC machining e fana ka ho nepahala ho phahameng le ho pheta-pheta bakeng sa likarolo tsa PEEK.
Ka lebaka la boemo bo phahameng ba ho qhibiliha ba PEEK, litefiso tse potlakileng tsa phepelo le lebelo li ka sebelisoa nakong ea ts'ebetso ha li bapisoa le lipolima tse ling.Pele o qala ts'ebetso ea machining, litlhoko tse khethehileng tsa ho sebetsana le thepa li tlameha ho finyelloa ho qoba khatello ea kelello ea ka hare le mapheo a amanang le mocheso nakong ea mochine.Litlhoko tsena li fapana ho ea ka kereiti ea lisebelisoa tsa PEEK tse sebelisitsoeng mme lintlha tse felletseng mabapi le sena li fanoe ke moetsi oa sehlopha seo.
PEEK e matla ebile e thata ho feta li-polymers tse ngata, empa e bonolo ho feta litšepe tse ngata.Sena se hloka ts'ebeliso ea lisebelisoa nakong ea mochini ho netefatsa mochini o nepahetseng.PEEK ke polasetiki ea boenjiniere ea mocheso o phahameng, 'me mocheso o hlahisoang nakong ea ts'ebetso o ke ke oa qhaloa ka ho feletseng.Sena se hloka tšebeliso ea thekenoloji e loketseng ho qoba letoto la mathata ka lebaka la ho senya mocheso o sa sebetseng oa thepa.
Litlhokomelo tsena li kenyelletsa ho cheka mekoti e tebileng le tšebeliso ea sepholi se lekaneng mesebetsing eohle ea mochini.Ka bobeli li-coolants tse thehiloeng ho petroleum le metsi li ka sebelisoa.
Ntho e 'ngoe ea bohlokoa e lokelang ho nahanoa ke ho roala lisebelisoa nakong ea machining ea PEEK ha ho bapisoa le li-plastiki tse ling tse seng kae tse lumellanang.Ho sebelisa limaraka tsa PEEK tse matlafalitsoeng ke k'habone ho kotsi haholo ho lisebelisoa.Boemo bona bo hloka lisebelisoa tsa carbide ho etsa limaraka tse tloaelehileng tsa thepa ea PEEK, le lisebelisoa tsa daemane bakeng sa limaraka tsa PEEK tse matlafalitsoeng ka carbon fiber.Tšebeliso ea sepholi le eona e ka ntlafatsa bophelo ba lisebelisoa.
2. PEEK ente molding
Ho bopa ka ente ho bolela ho etsoa ha likarolo tsa thermoplastic ka ho kenya thepa e qhibilihisitsoeng ka har'a hlobo e seng e kopane.E sebelisoa ho etsa likarolo ka molumo o phahameng.Thepa e qhibilihisoa ka kamoreng e futhumetseng, sekoti sa helical se sebelisetsoa ho kopanya, ebe se kenngoa ka har'a mokoti oa hlobo moo thepa e pholileng ho theha sebopeho se tiileng.
Lisebelisoa tsa Granular PEEK li sebelisoa bakeng sa ho bopa ente le ho bopa ha compression.PEEK ea Granular e tsoang ho bahlahisi ba fapaneng e hloka mekhoa ea ho omisa e fapaneng hanyane, empa hangata lihora tse 3 ho isa ho tse 4 ho 150 °C ho isa ho 160 °C li lekane.
Mechini e tloaelehileng ea ente e ka sebelisoa bakeng sa ho etsa ente ea thepa ea PEEK kapa hlobo ea PEEK, kaha mechini ena e ka fihlela mocheso oa mocheso oa 350 ° C ho isa ho 400 ° C, o lekaneng hoo e ka bang limaraka tsohle tsa PEEK.
Ho pholile ha hlobo ho hloka tlhokomelo e khethehileng, kaha ho se lumellane hofe kapa hofe ho tla lebisa liphetohong tsa sebopeho sa thepa ea PEEK.Ho kheloha leha e le hofe ho tloha mohahong oa semi-crystalline ho lebisa liphetohong tse sa rateheng ho litšobotsi tsa PEEK.
Maemo a ts'ebeliso ea lihlahisoa tsa PEEK
1. Likarolo tsa bongaka
Ka lebaka la biocompatibility ea thepa ea PEEK, e sebelisoa haholo lits'ebetsong tsa bongaka, ho kenyelletsa le ho kenngoa ha likarolo tsa 'mele oa motho ka nako e fapaneng.Likarolo tse entsoeng ka thepa ea PEEK le tsona li sebelisoa hangata mekhoeng e fapaneng ea phepelo ea lithethefatsi.
Lisebelisoa tse ling tsa bongaka li kenyelletsa likatiba tsa pholiso ea meno, li-washer tse nchocho, lisebelisoa tsa ho lokisa likotsi, le lisebelisoa tsa mokokotlo oa mokokotlo, har'a tse ling.
2. Likarolo tsa sefofane
Ka lebaka la ho lumellana ha PEEK le lits'ebetso tsa vacuum tse phahameng haholo, conductivity ea mocheso le ho hanyetsa mahlaseli, le lik'hemik'hale tse hanyetsanang le lik'hemik'hale, likarolo tse entsoeng ka thepa ea PEEK li sebelisoa haholo lits'ebetsong tsa sefofane ka lebaka la matla a tsona a phahameng.
3. Likarolo tsa likoloi
Li-bearings le mefuta e fapaneng ea mehele le tsona li entsoe ka PEEK.Ka lebaka la karo-karolelano e ntle ea boima ba 'mele ho boima ba PEEK, e sebelisoa ho etsa likarolo tsa li-block tsa enjine ea mabelo.
4. Khoele le lisebelisoa tsa motlakase / lisebelisoa tsa elektronike
Ho kenngoa ha cable ho entsoe ka PEEK, e ka sebelisoang lits'ebetsong tse kang lisebelisoa tsa motlakase oa lifofane mererong ea tlhahiso.
PEEK e na le lisebelisoa tsa mochini, tsa mocheso, tsa lik'hemik'hale le tsa motlakase tse etsang hore e be thepa ea khetho bakeng sa lits'ebetso tse 'maloa tsa boenjiniere.PEEK e fumaneha ka mefuta e fapaneng (melamu, likhoele, pellets) mme e ka sebetsoa ka machining a CNC, ho bopa ente.Mechini ea Goodwill Precision e 'nile ea ameha ka ho teba lefapheng la ho sebetsa ka mokhoa o nepahetseng ka lilemo tse 18.E na le boiphihlelo ba nako e telele bo bokelletsoeng ts'ebetsong e fapaneng ea lisebelisoa le boiphihlelo bo ikhethang ba ts'ebetso ea thepa.Haeba u na le likarolo tse tsamaellanang tsa PEEK tse hlokang ho sebetsoa, ka kopo ikopanye le rona!Re tla felehetsa boleng ba likarolo tsa hau ka pelo eohle ka tsebo ea rona ea lilemo tse 18 ea thepa le theknoloji ea ho sebetsa.
