Emikhakheni eminingi, i-PEEK ivame ukusetshenziselwa ukufeza izakhiwo ezifana nalezo ezinikezwa yizinsimbi kanye nezicelo ngaphansi kwezimo ezinzima.Isibonelo, izinhlelo zokusebenza eziningi zidinga ukumelana nokucindezelwa isikhathi eside, ukumelana nokugqokwa, amandla aqinile nokusebenza okuphezulu, nokumelana nokugqwala.Embonini kawoyela negesi, izinzuzo ezingaba khona zezinto ze-PEEK zingasetshenziswa.
Masifunde mayelana nokucutshungulwa kanye nokusetshenziswa kwezinto zokubheka.
Esinye sezizathu zokusetshenziswa kabanzi kwe-PEEK ezinhlelweni zobunjiniyela ukutholakala kwezinketho eziningi nezimo zokucubungula, okuwumshini, ukwakhiwa kwefilament ehlanganisiwe, ukuphrinta kwe-3D, nokubumba umjovo, ukwenza amajiyometri afiswayo kuzo zombili izindawo eziphilayo nezinomanzi.
Izinto ze-PEEK zitholakala ngendlela yenduku, i-valve yepuleti ecindezelweyo, ifomu le-filament kanye nefomu le-pellet, elingasetshenziselwa umshini we-CNC, ukuphrinta kwe-3D nokubumba umjovo ngokulandelanayo.
1. Ukucubungula kwe-PEEK CNC
I-CNC (ukulawula izinombolo zekhompuyutha) kuhlanganisa okuhlukile kokugaywa kwe-multi-axis, ukujika nokukhipha umshini kagesi (EDM) ukuze kutholwe ijometri yokugcina oyifunayo.Inzuzo eyinhloko yale mishini yikhono lokulawula umshini ngokusebenzisa izilawuli ezithuthukile ngokusebenzisa amakhodi akhiqizwe ngekhompuyutha ukuze wenze umshini womshini wokucophelela ocoke kakhulu wesiqeshana somsebenzi oyifunayo.
Imishini ye-CNC ihlinzeka ngezimo zokwakha amajiyometri ayinkimbinkimbi ezintweni ezihlukene, kusukela kumapulasitiki kuya ezinsimbi, kuyilapho kuhlangatshezwana nemikhawulo edingekayo yokubekezelela ijometri.Impahla ye-PEEK ingacutshungulwa ibe amaphrofayili ejiyomethri ayinkimbinkimbi, futhi ingacutshungulwa futhi ibe yizinga lezokwelapha kanye nezingxenye zebanga lezimboni ze-PEEK.Imishini ye-CNC inikeza ukunemba okuphezulu nokuphindaphinda kwezingxenye ze-PEEK.
Ngenxa yephoyinti eliphezulu lokuncibilika le-PEEK, amanani okuphakelayo asheshayo nesivinini angasetshenziswa phakathi nokucubungula uma kuqhathaniswa namanye ama-polymer.Ngaphambi kokuqala inqubo yokwenza imishini, izidingo ezikhethekile zokuphatha izinto kufanele zihlangatshezwe ukuze kugwenywe ukucindezelwa kwangaphakathi kanye nokuqhekeka okuhlobene nokushisa ngesikhathi somshini.Lezi zidingo ziyahlukahluka ngokuya ngebanga lezinto ze-PEEK ezisetshenzisiwe futhi imininingwane egcwele kulokhu inikezwa umkhiqizi walelo banga.
I-PEEK inamandla futhi ilukhuni kunama-polymer amaningi, kodwa ithambile kunezinsimbi eziningi.Lokhu kudinga ukusetshenziswa kwezinto zokulungisa ngesikhathi somshini ukuze kuqinisekiswe umshini onembile.I-PEEK iyipulasitiki yobunjiniyela bokushisa okuphezulu, futhi ukushisa okukhiqizwa phakathi nokucubungula akukwazi ukuchithwa ngokuphelele.Lokhu kudinga ukusetshenziswa kobuchwepheshe obufanele ukuze kugwenywe uchungechunge lwezinkinga ngenxa yokushabalaliswa kokushisa okungasebenzi kahle kwezinto.
Lezi zinyathelo zokuphepha zihlanganisa ukubhoboza imbobo ejulile kanye nokusetshenziswa kwesipholile esanele kuyo yonke imisebenzi yomshini.Kokubili okupholisayo okusekelwe ku-petroleum kanye namanzi kungasetshenziswa.
Enye into ebalulekile okufanele icatshangelwe ukugqokwa kwamathuluzi ngesikhathi somshini we-PEEK uma kuqhathaniswa namanye amapulasitiki ahambisanayo ambalwa.Ukusebenzisa amamaki e-PEEK aqiniswe nge-carbon fibre kuyingozi kakhulu ekusetshenzisweni kwamathuluzi.Lesi simo sidinga amathuluzi e-carbide omshini amamaki avamile wento ye-PEEK, namathuluzi edayimane amamaki e-PEEK aqiniswe nge-carbon fiber.Ukusetshenziswa kwe-coolant nakho kungathuthukisa impilo yamathuluzi.
2. Ukubumba umjovo we-PEEK
Ukubumba umjovo kubhekise ekwakhiweni kwezingxenye ze-thermoplastic ngokujova izinto ezincibilikisiwe ezikhunjini ezihlanganiswe ngaphambili.Isetshenziselwa ukwenza izingxenye ngevolumu ephezulu.Impahla iyancibilika ekamelweni elishisayo, isikulufu se-helical sisetshenziselwa ukuxuba, bese sijova emgodini wesikhunta lapho okuphola khona ukuze kwakhiwe isimo esiqinile.
I-PEEK ye-Granular isetshenziselwa ukubumba umjovo nokubunjwa kokucindezela.I-PEEK ye-Granular evela kubakhiqizi abahlukene idinga izinqubo zokumisa ezihluke kancane, kodwa ngokuvamile amahora angu-3 kuya kwangu-4 ku-150 °C kuya ku-160 °C anele.
Imishini ejwayelekile yokubumba umjovo ingasetshenziselwa ukubumba umjovo wempahla ye-PEEK noma isikhunta i-PEEK, njengoba le mishini ingafinyelela izinga lokushisa lokushisa elingu-350°C kuya ku-400°C, elanele cishe wonke amabanga e-PEEK.
Ukupholisa isikhunta kudinga ukunakwa okukhethekile, njengoba noma yikuphi ukungahambisani kuzoholela ekushintsheni kwesakhiwo sezinto ze-PEEK.Noma yikuphi ukuchezuka kusuka esakhiweni se-semi-crystalline kuholela ezinguqukweni ezingathandeki ezicini zesici ze-PEEK.
Izimo zohlelo lokusebenza lwemikhiqizo ye-PEEK
1. Izingxenye zezokwelapha
Ngenxa ye-biocompatibility yezinto ze-PEEK, isetshenziswa kabanzi ezinhlelweni zezokwelapha, okuhlanganisa ukufakwa kwezingxenye emzimbeni womuntu izikhathi ezihlukahlukene zesikhathi.Izingxenye ezenziwe ngezinto ze-PEEK nazo zivame ukusetshenziswa ezinhlelweni ezihlukene zokulethwa kwezidakamizwa.
Ezinye izinhlelo zokusebenza zezokwelapha zihlanganisa amakepisi okuphulukisa amazinyo, amawasha acijile, amadivaysi okulungisa ukuhlukumezeka, kanye namadivayisi wokuhlanganisa umgogodla, phakathi kokunye.
2. Izingxenye ze-Aerospace
Ngenxa yokuhambisana kwe-PEEK nezicelo ze-vacuum ephezulu kakhulu, ukuqhutshwa kwe-thermal nokumelana nemisebe, nokumelana namakhemikhali, izingxenye ezenziwe ngezinto ze-PEEK zisetshenziswa kakhulu ekusetshenzisweni kwe-aerospace ngenxa yamandla azo aphezulu.
3. Izingxenye zezimoto
Amabhere kanye nezinhlobo ezahlukene zamasongo nazo zenziwe nge-PEEK.Ngenxa yesilinganiso esihle kakhulu se-PEEK sesisindo-kumandla, isetshenziselwa ukwenza izingxenye zamabhulokhi enjini yomjaho.
4. Ukufakwa kwezintambo nezintambo/izinhlelo ze-elekthronikhi
Ukufakwa kwekhebula kwenziwa nge-PEEK, engasetshenziswa ezinhlelweni ezifana nezinhlelo zikagesi zezindiza kumaphrojekthi wokukhiqiza.
I-PEEK inezinto zokusebenzisa, ezishisayo, zamakhemikhali nezikagesi eziyenza ibe yinto yokuzikhethela ezinhlelweni eziningi zobunjiniyela.I-PEEK itholakala ngezindlela ezihlukahlukene (izinduku, imicu, amapellets) futhi ingacutshungulwa ngomshini we-CNC, ukubumba umjovo.I-Goodwill Precision Machinery ibambe iqhaza ngokujulile emkhakheni wokwenza imishini ngokunemba iminyaka engu-18.Inolwazi oluqoqiwe lwesikhathi eside ekucutshungulweni kwezinto ezihlukene kanye nesipiliyoni esiyingqayizivele sokucubungula izinto.Uma unezingxenye ezihambisanayo ze-PEEK ezidinga ukucutshungulwa, sicela usithinte!Sizophelezela ngenhliziyo yonke ikhwalithi yezingxenye zakho ngolwazi lwethu lweminyaka engu-18 lwezinto zokwakha kanye nobuchwepheshe bokucubungula.
