Muminda mizhinji, PEEK inowanzoshandiswa kuwana zvivakwa zvakafanana nezvinopihwa nesimbi uye maapplication pasi pemamiriro akaomarara.Semuenzaniso, akawanda maapplication anoda kwenguva refu yekumanikidza kuramba, kupfeka kuramba, kusimba kwesimba uye kuita kwepamusoro, uye kusagadzikana kwekuora.Muindasitiri yeoiri negasi, zvakanakira zvePEEK zvinhu zvinogona kushandiswa.
Ngatidzidzei nezve kugadzirisa uye kushandiswa kwezvinhu zvepeek.
Chimwe chezvikonzero zvekushandiswa kwakapararira kwePEEK mumashandisirwo einjiniya kuvepo kwesarudzo dzakawanda uye mamiriro ekugadzirisa, zvinoti machining, fused filament fabrication, 3D kudhinda, uye jekiseni rekugadzira, kugadzira majeometri anodiwa munzvimbo dzese dziri organic uye dzine mvura.
PEEK zvinhu zvinowanikwa mutsvimbo fomu, compressed plate valve, filament fomu uye pellet fomu, inogona kushandiswa CNC machining, 3D kudhinda uye jekiseni molding zvichiteerana.
1. PEEK CNC kugadzirisa
CNC (kombuta nhamba yekudzora) machining ine akasiyana akasiyana e-multi-axis milling, kutendeuka uye magetsi ekuburitsa machining (EDM) kuti uwane inodiwa yekupedzisira geometry.Mukana mukuru wemichina iyi kugona kudzora muchina kuburikidza nevatongi vepamusoro kuburikidza nekombuta-yakagadzirwa macode kuita yakakwirira-chaiyo yakanaka machining yeinodiwa workpiece.
CNC machining inopa mamiriro ekugadzira akaomarara geometries muzvinhu zvakasiyana, kubva kumapurasitiki kusvika kusimbi, uchisangana neinodiwa geometric kushivirira miganhu.PEEK zvinhu zvinogona kugadziriswa kuita yakaoma geometric profiles, uye zvakare inogona kugadziriswa kuita yekurapa giredhi uye maindasitiri giredhi PEEK zvikamu.CNC machining inopa yakanyanya kurongeka uye kudzokorora kwezvikamu zvePEEK.
Nekuda kwePEEK's high melting point, kukurumidza kunyungudika mitengo uye kumhanya kunogona kushandiswa panguva yekugadziriswa zvichienzaniswa nemamwe mapolymer.Usati watanga maitiro ekugadzira, zvakakosha zvekubata zvinhu zvinodikanwa zvinofanirwa kusangana kuti zvidzivise kushushikana kwemukati uye kutsemuka kwakabatana nekupisa panguva yekugadzira.Izvi zvinodikanwa zvinosiyana zvichienderana negiredhi rePEEK zvinhu zvakashandiswa uye zvizere zvizere pane izvi zvinopihwa nemugadziri weiyo giredhi.
PEEK yakasimba uye yakaoma kupfuura mapolima mazhinji, asi yakapfava kupfuura simbi zhinji.Izvi zvinoda kushandiswa kwezvigadziriso panguva yekugadzira kuve nechokwadi chekugadzira machining.PEEK ipurasitiki yeinjiniya yakanyanya-kupisa, uye kupisa kunogadzirwa panguva yekugadziriswa hakugone kubviswa zvizere.Izvi zvinoda kushandiswa kwehunyanzvi hwakakodzera kuti udzivise matambudziko akateedzana nekuda kwekutadza kupisa kwekupisa kwezvinhu.
Aya ekuchenjerera anosanganisira kuchera gomba rakadzika uye kushandisa inotonhorera yakakwana mumabasa ese emuchina.Zvose petroleum-based uye mvura-based coolants zvinogona kushandiswa.
Chimwe chinhu chakakosha kufunga nezvekushandisa kupfeka panguva yekugadzira PEEK zvichienzaniswa nemamwe mashoma anoenderana mapurasitiki.Kushandisa kabhoni faibha yakasimbiswa PEEK mamakisi kunonyanya kukanganisa kukushandisa.Mamiriro ezvinhu aya anoda maturusi ecarbide kumichina magiredhi akajairwa ePEEK zvinhu, uye maturusi edhaimondi ekabhoni fiber akasimbisa PEEK mamakisi.Kushandiswa kwezvinotonhorera kunogonawo kuvandudza hupenyu hwezvishandiso.
2. PEEK jekiseni molding
Jekiseni molding inoreva kugadzirwa kwezvikamu zve thermoplastic nekubaya zvinhu zvakanyungudutswa mu mold dzakafanounganidzwa.Inoshandiswa kugadzira zvikamu muhuwandu hwepamusoro.Izvo zvinhu zvinonyungudutswa mukamuri inopisa, helical screw inoshandiswa kusanganisa, uye yobva yapinzwa mugomba rekuumbwa umo zvinhu zvinotonhora kuita chimiro chakasimba.
Granular PEEK zvinhu zvinoshandiswa jekiseni kuumba uye compression molding.Granular PEEK kubva kune vagadziri vakasiyana inoda zvishoma zvakasiyana nzira dzekuomesa, asi kazhinji maawa matatu kusvika mana pa150 °C kusvika 160 °C inokwana.
Majekiseni ekuumba majekiseni anogona kushandiswa kuumba jekiseni rePEEK zvinhu kana mold PEEK, sezvo michina iyi inogona kusvika pakudziya kwe350 ° C kusvika 400 ° C, iyo inokwana kunenge ese maPEEK mamakisi.
Kutonhora kwe mold kunoda kutariswa kwakakosha, sezvo kusawirirana kupi zvako kunozotungamira mukushandurwa kwechimiro chePEEK zvinhu.Chero kutsauka kubva kune semi-crystalline chimiro kunotungamira kune zvisingadiwe shanduko muhunhu hwePEEK.
Mamiriro ekushandisa ezvigadzirwa zvePEEK
1. Zvikamu zvekurapa
Nekuda kweiyo biocompatibility yezvinhu zvePEEK, inoshandiswa zvakanyanya mumashandisirwo ekurapa, kusanganisira kuiswa kwezvikamu mumuviri wemunhu kwenguva dzakasiyana.Zvikamu zvinogadzirwa zvePEEK zvinhu zvinowanzo shandiswa mumasisitimu akasiyana ekutakura zvinodhaka.
Zvimwe zvikumbiro zvekurapa zvinosanganisira mazino ekuporesa zvivharo, akanongedza washers, trauma fixation zvishandiso, uye spinal fusion zvishandiso, pakati pezvimwe.
2. Zvikamu zvemuchadenga
Nekuda kwekuenderana kwePEEK ne-ultra-high vacuum applications, thermal conductivity uye radiation resistance, uye chemical resistance, zvikamu zvakagadzirwa nePEEK zvinhu zvinoshandiswa zvakanyanya mukushandisa aerospace nekuda kwekusimba kwazvo.
3. Zvikamu zvemotokari
Bearings nemhando dzakasiyana dzemhete dzakagadzirwawo nePEEK.Nekuda kwePEEK yakanakisa huremu-kune-simba reshiyo, inoshandiswa kugadzira zvikamu zvemijaho ejini.
4. Wire uye tambo insulation / electronic applications
Cable insulation inogadzirwa nePEEK, inogona kushandiswa mukushandisa senge ndege dzemagetsi masisitimu mumapurojekiti ekugadzira.
PEEK ine michina, inopisa, makemikari uye magetsi zvivakwa zvinoita kuti ive chinhu chesarudzo kune akati wandei einjiniya maapplication.PEEK inowanikwa nenzira dzakasiyana siyana (tsvimbo, filaments, pellets) uye inogona kugadziriswa neCNC machining, jekiseni kuumba.Goodwill Precision Machinery yanga ichibatanidzwa zvakanyanya mumunda weiyo chaiyo machining kwemakore gumi nemasere.Iyo ine ruzivo rwenguva refu rwakaunganidzirwa mumhando dzakasiyana dzekugadzirisa zvinhu uye yakasarudzika ruzivo rwekugadzirisa zvinhu.Kana uine zvikamu zvinoenderana nePEEK zvinoda kugadziriswa, ndapota taura nesu!Isu tichaperekedza nemoyo wese kunaka kwezvikamu zvako neruzivo rwedu rwemakore gumi nemasere ezvigadzirwa uye tekinoroji yekugadzirisa.
