M'madera ambiri, PEEK nthawi zambiri amagwiritsidwa ntchito kuti akwaniritse zinthu zofanana ndi zomwe zimaperekedwa ndi zitsulo ndi ntchito pansi pa zovuta.Mwachitsanzo, ntchito zambiri zimafunikira kukana kwanthawi yayitali, kukana kuvala, kulimba kwamphamvu komanso magwiridwe antchito apamwamba, komanso kukana dzimbiri.M'makampani amafuta ndi gasi, zabwino zomwe zitha kugwiritsidwa ntchito pazinthu za PEEK zitha kugwiritsidwa ntchito.
Tiyeni tiphunzire za kukonza ndi kugwiritsa ntchito zinthu zowonera.
Chimodzi mwazifukwa zofala kwambiri za PEEK mu ntchito zauinjiniya ndi kupezeka kwa zosankha zingapo ndikusintha momwe zinthu zimapangidwira, zomwe ndi makina, kupanga ulusi wosakanikirana, kusindikiza kwa 3D, ndi kuumba jekeseni, kupanga ma geometri omwe amafunidwa m'malo achilengedwe komanso amadzi.
PEEK zinthu zimapezeka mu ndodo mawonekedwe, wothinikizidwa mbale valavu, filament mawonekedwe ndi pellet mawonekedwe, amene angagwiritsidwe ntchito CNC Machining, 3D kusindikiza ndi jekeseni akamaumba motsatana.
1. PEEK CNC processing
Makina a CNC (kuwongolera manambala apakompyuta) amakhala ndi mitundu yosiyanasiyana ya mphero yamitundu yambiri, kutembenuza ndi kutulutsa magetsi (EDM) kuti mupeze geometry yomaliza yomwe mukufuna.Ubwino waukulu wa makinawa ndikutha kuwongolera makinawo kudzera mwa owongolera apamwamba kudzera pamakhodi opangidwa ndi makompyuta kuti apange makina abwino kwambiri opangira ntchito yomwe mukufuna.
CNC Machining imapereka mikhalidwe yopangira ma geometri ovuta muzinthu zosiyanasiyana, kuchokera ku pulasitiki kupita kuzitsulo, ndikukwaniritsa malire ovomerezeka a geometric.Zinthu za PEEK zitha kusinthidwa kukhala mbiri zovuta za geometric, komanso zitha kusinthidwa kukhala magawo azachipatala komanso magawo a PEEK amakampani.Makina a CNC amapereka kulondola kwambiri komanso kubwereza kwa magawo a PEEK.
Chifukwa cha kusungunuka kwa PEEK, kuchuluka kwa chakudya komanso kuthamanga kungagwiritsidwe ntchito pokonza poyerekeza ndi ma polima ena.Musanayambe kupanga makina, zofunikira zapadera zogwirira ntchito ziyenera kukwaniritsidwa kuti mupewe kupsinjika kwamkati ndi ming'alu yokhudzana ndi kutentha panthawi yokonza.Zofunikira izi zimasiyana malinga ndi mtundu wa zinthu za PEEK zomwe zimagwiritsidwa ntchito ndipo zambiri za izi zimaperekedwa ndi wopanga girediyo.
PEEK ndi yamphamvu komanso yolimba kuposa ma polima ambiri, koma ndi yofewa kuposa zitsulo zambiri.Izi zimafuna kugwiritsa ntchito zida zomangira pakupanga makina kuti zitsimikizire kuti makinawa ali olondola.PEEK ndi pulasitiki yaumisiri yotentha kwambiri, ndipo kutentha komwe kumapangidwa pokonza sikungathe kutayidwa.Izi zimafuna kugwiritsa ntchito teknoloji yoyenera kuti tipewe mavuto angapo chifukwa cha kutentha kosakwanira kwa zipangizo.
Njira zodzitetezerazi zimaphatikizapo kubowola dzenje lakuya komanso kugwiritsa ntchito zoziziritsa kukhosi zokwanira pamakina onse.Zida zoziziritsa kukhosi zochokera ku petroleum komanso zamadzi zitha kugwiritsidwa ntchito.
Chinthu chinanso choyenera kuganizira ndi kuvala kwa zida panthawi yokonza PEEK poyerekeza ndi mapulasitiki ena ochepa omwe amagwirizana.Kugwiritsa ntchito kaboni fiber reinforced PEEK magiredi kumawononga kwambiri zida.Izi zimafuna zida za carbide zopangira magiredi wamba a zinthu za PEEK, ndi zida za diamondi zamagiredi a carbon fiber olimbitsa PEEK.Kugwiritsa ntchito koziziritsa kungathenso kusintha moyo wa zida.
2. PEEK jekeseni akamaumba
Kuumba jekeseni kumatanthauza kupanga zigawo za thermoplastic pobaya zinthu zosungunula mu zisankho zomwe zidapangidwa kale.Amagwiritsidwa ntchito popanga magawo amphamvu kwambiri.Zinthuzo zimasungunuka m'chipinda chotenthedwa, chowotcha cha helical chimagwiritsidwa ntchito kusakaniza, kenako chimalowetsedwa mu nkhungu pomwe zinthuzo zimazizira kuti zikhale zolimba.
Granular PEEK zakuthupi zimagwiritsidwa ntchito popanga jakisoni ndi kuponderezana.Granular PEEK kuchokera kwa opanga osiyanasiyana imafuna njira zoyanika zosiyana pang'ono, koma nthawi zambiri maola 3 mpaka 4 pa 150 °C mpaka 160 °C ndi okwanira.
Makina opangira jakisoni okhazikika atha kugwiritsidwa ntchito popanga jakisoni wazinthu za PEEK kapena nkhungu PEEK, popeza makinawa amatha kufikira kutentha kwa 350 ° C mpaka 400 ° C, komwe kumakhala kokwanira pafupifupi magiredi onse a PEEK.
Kuzizira kwa nkhungu kumafuna chisamaliro chapadera, chifukwa kusagwirizana kulikonse kudzatsogolera kusintha kwa kapangidwe kazinthu za PEEK.Kupatuka kulikonse kuchokera pamapangidwe a semi-crystalline kumabweretsa kusintha kosafunikira mu mawonekedwe a PEEK.
Zochitika zogwiritsira ntchito zinthu za PEEK
1. Zigawo zachipatala
Chifukwa cha biocompatibility ya zinthu za PEEK, zimagwiritsidwa ntchito kwambiri pazachipatala, kuphatikizapo kuikidwa kwa zigawo zina m'thupi la munthu kwa nthawi zosiyanasiyana.Zida zopangidwa ndi PEEK zimagwiritsidwanso ntchito m'njira zosiyanasiyana zoperekera mankhwala.
Ntchito zina zamankhwala zimaphatikizapo zipewa zochizira mano, ma washer osongoka, zida zowongolera zoopsa, ndi zida zophatikizira msana, pakati pa ena.
2. Zigawo zamlengalenga
Chifukwa chogwirizana ndi PEEK ndi ma ultra-high vacuum applications, kutentha kwa kutentha ndi kukana kwa radiation, komanso kukana kwa mankhwala, zigawo zopangidwa ndi PEEK zimagwiritsidwa ntchito kwambiri popanga ndege chifukwa cha mphamvu zawo zolimba.
3. Zigawo zamagalimoto
Zonyamula ndi mitundu yosiyanasiyana ya mphete zimapangidwanso ndi PEEK.Chifukwa cha kuchuluka kwa kulemera kwamphamvu kwa PEEK, imagwiritsidwa ntchito popanga zida zama injini othamanga.
4. Waya ndi kusungunula chingwe / ntchito zamagetsi
Kusungunula chingwe kumapangidwa ndi PEEK, yomwe imatha kugwiritsidwa ntchito ngati makina amagetsi oyendetsa ndege popanga.
PEEK ili ndi makina, matenthedwe, mankhwala ndi magetsi zomwe zimapangitsa kuti ikhale yosankhika pamakina angapo.PEEK imapezeka m'njira zosiyanasiyana (ndodo, filaments, pellets) ndipo imatha kukonzedwa ndi makina a CNC, kuumba jekeseni.Goodwill Precision Machinery wakhala akukhudzidwa kwambiri ndi makina olondola kwa zaka 18.Iwo ali ndi nthawi yaitali anasonkhanitsa zinthu zosiyanasiyana processing ndi wapadera zinthu processing zinachitikira.Ngati muli ndi magawo ofanana a PEEK omwe akufunika kukonzedwa, chonde titumizireni!Tidzaperekeza ndi mtima wonse mawonekedwe a magawo anu ndi chidziwitso chathu chazaka 18 cha zida ndi ukadaulo wopanga.
