Kwiinkalo ezininzi, i-PEEK isoloko isetyenziselwa ukufezekisa iipropati ezifanayo nezo zinikezelwa ngesinyithi kunye nezicelo phantsi kweemeko ezinzima.Ngokomzekelo, izicelo ezininzi zifuna ukuxhathisa ukunyanzeliswa kwexesha elide, ukumelana nokunxiba, amandla okuqina kunye nokusebenza okuphezulu, kunye nokuxhathisa ukubola.Kwishishini leoli kunye negesi, iingenelo ezinokubakho zezinto zePEEK zingasetyenziswa.
Masifunde malunga nokulungiswa kunye nokusetyenziswa kwemathiriyeli yepeek.
Esinye sezizathu zokusetyenziswa ngokubanzi kwe-PEEK kwizicelo zobunjineli kukufumaneka kokhetho oluninzi kunye neemeko zokusetyenzwa, ezizezi, ukwenziwa komatshini, ukwenziwa kwefilament edityanisiweyo, ushicilelo lwe-3D, kunye nokubumba inaliti, ukwenza iijiyometri ezinqwenelekayo kuzo zombini iindawo eziphilayo kunye namanzi.
Izinto ze-PEEK zifumaneka kwifom yentonga, i-valve yeplate egxininisiweyo, ifom ye-filament kunye nefom ye-pellet, engasetyenziselwa i-CNC machining, i-3D yokushicilela kunye ne-injection molding ngokulandelanayo.
1. PEEK CNC processing
I-CNC (ulawulo lwamanani ekhompyutheni) i-machining iqulethe iindidi ezahlukeneyo ze-multi-axis milling, i-turning kunye ne-electrical discharge machining (EDM) ukufumana i-geometry yokugqibela efunekayo.Inzuzo ephambili yale mishini kukukwazi ukulawula umatshini ngokusebenzisa abalawuli abaphambili ngokusebenzisa iikhowudi ezenziwe ngekhompyutha ukwenza umatshini ochanekileyo ochanekileyo womsebenzi ofunekayo.
Umatshini we-CNC ubonelela ngeemeko zokudala iijometri ezintsonkothileyo kwizinto ezahlukeneyo, ukusuka kwiiplastiki ukuya kwisinyithi, ngelixa udibana nemida yokunyamezela yejometri.Izinto ze-PEEK zinokucutshungulwa zibe ziiprofayili zejometri ezintsonkothileyo, kwaye zinokucutshungulwa kwinqanaba lezonyango kunye nebakala leshishini lePEEK.Umatshini we-CNC ubonelela ngokuchaneka okuphezulu kunye nokuphindaphinda kwamalungu e-PEEK.
Ngenxa yenqanaba eliphezulu lokunyibilika kwe-PEEK, amazinga okutya okukhawulezayo kunye nezantya zinokuqashwa ngexesha lokucubungula xa kuthelekiswa nezinye iipolima.Ngaphambi kokuqala inkqubo yomatshini, iimfuno ezikhethekileyo zokusingatha izinto kufuneka zifezekiswe ukuze zigweme uxinzelelo lwangaphakathi kunye nokuqhekeka okuhambelana nobushushu ngexesha lomatshini.Ezi mfuno ziyahluka ngokwebakala lezinto zePEEK ezisetyenzisiweyo kunye neenkcukacha ezipheleleyo kule nto zinikwe ngumenzi welo bakala.
I-PEEK yomelele kwaye ilukhuni kuneepholima ezininzi, kodwa ithambe kuneentsimbi ezininzi.Oku kufuna ukusetyenziswa kwezixhobo ngexesha lomatshini ukuze kuqinisekiswe umatshini ochanekileyo.I-PEEK yiplastiki yobunjineli bobushushu obuphezulu, kwaye ubushushu obuveliswe ngexesha lokulungiswa abunakuchithwa ngokupheleleyo.Oku kufuna ukusetyenziswa kweteknoloji efanelekileyo ukuphepha uchungechunge lweengxaki ngenxa yokutshatyalaliswa kobushushu obungasebenziyo bezinto eziphathekayo.
Ezi zilumkiso ziquka ukugrumba umngxuma onzulu kunye nokusetyenziswa kwesipholisi esaneleyo kuyo yonke imisebenzi yomatshini.Zombini izizipholisi ezisekwe kwipetroleum kunye namanzi zingasetyenziswa.
Enye into ebalulekileyo ekufuneka iqwalaselwe kukunxitywa kwesixhobo ngexesha lokwenziwa kwe-PEEK xa kuthelekiswa nezinye iiplastiki ezimbalwa ezihambelanayo.Ukusebenzisa i-carbon fibre eyomeleziweyo amabanga e-PEEK kuyingozi kakhulu kwisixhobo.Le meko ifuna izixhobo ze-carbide kumatshini amabakala aqhelekileyo ezinto ze-PEEK, kunye nezixhobo zedayimane ze-carbon fiber eziqiniswe ngamabakala e-PEEK.Ukusetyenziswa kwesipholisi kunokuphucula ubomi besixhobo.
2. Ukubumba inaliti ye-PEEK
Isitofu sokubumba sibhekisa ekwenziweni kwamalungu e-thermoplastic ngokutofa imathiriyeli etyhidiweyo kwimold edityaniswe kwangaphambili.Isetyenziselwa ukwenza iinxalenye ezinomthamo ophezulu.Izinto eziphathekayo zinyibilika kwigumbi elifudumeleyo, i-helical screw isetyenziselwa ukuxuba, kwaye emva koko ifakwe kwi-mold cavity apho i-material iphola ukuze yenze ubume obuqinileyo.
Izinto ze-PEEK zeGranular zisetyenziselwa ukubunjwa kwesitofu kunye nokunyanzeliswa koxinzelelo.I-PEEK yeGranular evela kubavelisi abahlukeneyo ifuna iinkqubo zokomisa ezahlukileyo kancinci, kodwa ngokuqhelekileyo iiyure ezi-3 ukuya kwezi-4 kwi-150 °C ukuya kwi-160 °C zanele.
Imishini yokubumba i-injection eqhelekileyo ingasetyenziselwa ukubunjwa kwenaliti yezinto ze-PEEK okanye i-PEEK yokubumba, njengoko aba matshini banokufikelela kwiqondo lokushisa lokufudumeza kwe-350 ° C ukuya kwi-400 ° C, eyaneleyo phantse kuwo onke amabakala e-PEEK.
Ukupholisa isikhunta kufuna ingqalelo ekhethekileyo, njengoko nakuphi na ukungahambelani kuya kubangela utshintsho kwisakhiwo sezinto ze-PEEK.Nakuphi na ukuphambuka kwisakhiwo se-semi-crystalline kukhokelela kwiinguqu ezingathandekiyo kwiimpawu zeempawu ze-PEEK.
Iimeko zokusetyenziswa kweemveliso zePEEK
1. Amalungu ezonyango
Ngenxa ye-biocompatibility yezinto ze-PEEK, isetyenziswa ngokubanzi kwizicelo zonyango, kubandakanywa ukufakwa kwamacandelo emzimbeni womntu ngamaxesha ahlukeneyo.Amalungu enziwe ngezinto zePEEK asetyenziswa ngokuqhelekileyo kwiinkqubo ezahlukeneyo zokuhanjiswa kweziyobisi.
Ezinye izicelo zonyango ziquka i-caps yokuphulukisa amazinyo, i-washers ekhonjiweyo, izixhobo zokulungisa i-trauma, kunye nezixhobo zokudibanisa umgogodla, phakathi kwabanye.
2. Iindawo ze-Aerospace
Ngenxa yokuhambelana kwe-PEEK kunye nezicelo ze-vacuum ze-ultra-high, i-thermal conductivity kunye nokumelana nemitha, kunye nokumelana nemichiza, iinxalenye ezenziwe ngezinto ze-PEEK zisetyenziswa ngokubanzi kwizicelo ze-aerospace ngenxa yamandla abo aphezulu.
3. Iindawo zemoto
Iibheringi kunye neentlobo ezahlukeneyo zamakhonkco nazo zenziwe nge-PEEK.Ngenxa yomlinganiselo ogqwesileyo we-PEEK wobunzima bokomelela, isetyenziselwa ukwenza iinxalenye zeebhloko zenjini yomdyarho.
4. I-wire kunye ne-cable insulation / izicelo ze-elektroniki
Ukugquma kwekhebula kwenziwa nge-PEEK, enokusetyenziswa kwizicelo ezifana neenkqubo zombane zenqwelomoya kwiiprojekthi zokuvelisa.
I-PEEK inomatshini, i-thermal, iikhemikhali kunye neempawu zombane ezenza ukuba ibe yimathiriyeli yokuzikhethela kwizicelo ezininzi zobunjineli.I-PEEK ifumaneka kwiifom ezahlukeneyo (iintonga, iifilaments, iipellets) kwaye zinokucutshungulwa ngomatshini we-CNC, ukubunjwa kwenaliti.I-Goodwill Precision Machinery ibandakanyeke ngokunzulu kwintsimi yomatshini ochanekileyo iminyaka eyi-18.Inamava aqokelelweyo exesha elide ekusetyenzweni kwezinto ezahlukeneyo kunye namava okwenziwa kwezinto ezizodwa.Ukuba uneendawo ezihambelanayo zePEEK ezifuna ukusetyenzwa, nceda uqhagamshelane nathi!Siya kukhapha ngentliziyo epheleleyo umgangatho wamalungu akho ngolwazi lwethu lweminyaka eyi-18 yemathiriyeli kunye nokucubungula ubuchwepheshe.
