PEEK ke eng?
Polyether ether ketone(PEEK) ke thepa ea polymer e nkhang hamonate ea thermoplastic. Ke mofuta oa polasetiki e khethehileng ea boenjiniere e nang le ts'ebetso e babatsehang, haholo-holo e bontšang khanyetso e matla ea mocheso, ho hanyetsa likhohlano le botsitso ba sebopeho. E sebelisoa haholo sebakeng sa lifofane, sesole, koloi, meriana le masimo a mang.
Ts'ebetso ea mantlha ea PEEK
PEEK e na le matla a phahameng a mochine, ho hanyetsa mocheso o phahameng, ho hanyetsa tšusumetso, ho thibela lelakabe, acid le alkali resistance, hydrolysis resistance, abrasion resistance, ho hanyetsa mokhathala, ho hanyetsa mahlaseli le thepa e ntle ea motlakase.
Ke boemo bo phahameng ka ho fetisisa ba ho hanyetsa mocheso ka polasetiki e khethehileng ea boenjiniere.
Mocheso oa nako e telele oa tšebeletso o ka tloha ho -100 ℃ ho ea ho 260 ℃.
Lisebelisoa tsa polasetiki tsa PEEK li na le litšobotsi tse phahameng tsa botsitso. Tikoloho e nang le liphetoho tse kholo tsa mocheso le mongobo ha e na tšusumetso e nyane boholo ba likarolo tsa PEEK, 'me sekhahla sa ho fokotseha ha ente ea PEEK e nyane, e leng se etsang hore ho nepahala ha likarolo tsa PEEK ho phahame haholo ho feta tsa polasetiki e akaretsang, e ka fihlelang litlhoko tsa ho nepahala ha maemo a phahameng tlasa maemo a mosebetsi.
PEEK e na le mocheso o hlahelletseng - litšobotsi tse hananang le hydrolysis.
Sebakeng sa mocheso o phahameng le mongobo o phahameng ho kenngoa ha metsi ho tlaase haholo, ho tšoana le nylon le li-plastiki tse ling ka lebaka la ho kenngoa ha metsi le boholo ba liphetoho tse hlakileng.
PEEK e na le ho tiea ho hoholo le ho hanyetsa mokhathala, ho bapisoa le li-alloys, 'me e ka sebelisoa nako e telele libakeng tse thata tsa mosebetsi. Ho nkela sebaka sa tšepe, aluminium, koporo, titanium, ptFE le lisebelisoa tse ling tse phahameng, ho ntlafatsa ts'ebetso ea mochine ka nako e le 'ngoe ho fokotsa litšenyehelo haholo.
PEEK e na le tšireletso e ntle. Liphetho tsa liteko tsa UL tsa thepa li bonts'a hore index ea PEEK ea "flame retardation index" ke Kereiti ea V-0, e leng boemo bo nepahetseng ka ho fetesisa ba ho lieha ha lelakabe. Ho tuka ha PEEK (ke hore, mosi o hlahisoang nakong ea ho tuka ho sa khaotseng) ke o tlase ho feta polasetiki efe kapa efe.
Ho se khonehe ha khase ea PEEK (tekanyo ea khase e hlahisoang ha e bolile ka mocheso o phahameng) le eona e tlase.
Histori ea PEEK
PEEK ke thepa e kaholimo ho piramide ea polasetiki, 'me ke lik'hamphani tse' maloa lefatšeng tse nang le tsebo ea ho etsa polymerization.
PEEK e entsoe ke ICI lilemong tsa bo-1970. Ka lebaka la thepa ea eona e ikhethang ea mochini le thepa ea ho e lokisa, e ile ea fetoha e 'ngoe ea lipolasetiki tsa boenjiniere tse ikhethang ka ho fetisisa.
Theknoloji ea China ea PEEK e qalile lilemong tsa bo-1980. Ka mor'a lilemo tse ngata tsa lipatlisiso tse thata, Univesithi ea Jilin e ile ea hlahisa mokhoa oa PEEK resin synthesis ka litokelo tse ikemetseng tsa thepa ea mahlale. Hase feela hore ts'ebetso ea sehlahisoa e fihlile boemong ba PEEK ea linaheng tse ling, empa le lisebelisoa tse tala le lisebelisoa kaofela li thehiloe Chaena, ka katleho li fokotsa litšenyehelo tsa tlhahiso.
Hajoale, indasteri ea China ea PEEK e batla e holile, e na le boleng le tlhahiso e ts'oanang le ea baetsi ba kantle ho naha, 'me theko e tlase haholo ho feta mmaraka oa machabeng. Se hlokang ho ntlafatsoa ke mefuta e mengata ea mefuta-futa ea PEEK.
Victrex e ne e le tlatsetso ea ICI ea Borithane ho fihlela e hlakoloa.
E bile moetsi oa pele oa lefats'e oa PEEK.
Tšebeliso ea PEEK
1. Lisebelisoa tsa sepakapaka: ho nkela aluminium sebaka le litšepe tse ling bakeng sa likarolo tsa sefofane, bakeng sa li-slots tsa betri ea rocket, liboutu, linate le likarolo tsa lienjineri tsa rokete.
2. Kopo tšimong ea elektronike: filimi ea ho kenya letsoho, sehokelo, boto ea potoloho e hatisitsoeng, sehokelo sa mocheso o phahameng, potoloho e kopantsoeng, skeleton ea li-coil coil, coil coil, joalo-joalo.
3. Likopo ho mechine ea likoloi: li-bearings tsa likoloi, li-gaskets, li-seal, li-clutch, li-brake le li-air conditioning systems. Nissan, NEC, Sharp, Chrysler, GENERAL Motors, Audi, Airbus le ba bang ba qalile ho sebelisa thepa ka bongata.
4. Likopo lefapheng la bongaka: masapo a maiketsetso, setsi sa ho kenya meno, lisebelisoa tsa bongaka tse lokelang ho sebelisoa khafetsa.
