PEEK ni iki?
Polyther ether ketone(PEEK) ni ibikoresho bya termoplastique aromatic polymer. Nubwoko bwa plastike idasanzwe yubuhanga ifite imikorere myiza, cyane cyane yerekana ubushyuhe bukomeye cyane, kurwanya ubukana no guhagarara neza. Ikoreshwa cyane mu kirere, mu gisirikare, mu modoka, mu buvuzi no mu zindi nzego.
Ibikorwa by'ibanze bya PEEK
PEEK ifite imbaraga za mashini nyinshi, irwanya ubushyuhe bwinshi, irwanya ingaruka, irwanya flame, aside na alkali, kurwanya hydrolysis, kurwanya abrasion, kurwanya umunaniro, kurwanya imirasire hamwe nibintu byiza byamashanyarazi.
Nicyiciro cyo hejuru cyo kurwanya ubushyuhe muri plastiki idasanzwe yubuhanga.
Ubushyuhe bwigihe kirekire burashobora kuva kuri -100 ℃ kugeza 260 ℃.
PEEK ibikoresho fatizo bya pulasitike bifite urwego rwo hejuru rwo gutuza. Ibidukikije bifite ubushyuhe bunini nubushyuhe ntibifite ingaruka nke mubunini bwibice bya PEEK, kandi igipimo cyo kugabanya inshinge za PEEK ni gito, ibyo bigatuma ibipimo byerekana neza ibice bya PEEK birenze cyane ibya plastiki rusange, bishobora kuzuza ibisabwa murwego rwohejuru rwukuri mubihe byakazi.
PEEK ifite ubushyuhe bugaragara - ibiranga hydrolysis irwanya.
Mubidukikije byubushyuhe bwinshi nubushyuhe bwinshi amazi yinjira ni make cyane, asa na nylon hamwe nandi plastiki kubera kwinjiza amazi nubunini bwimpinduka zigaragara.
PEEK ifite ubukana buhebuje no kurwanya umunaniro, ugereranije na alloys, kandi irashobora gukoreshwa igihe kinini mugusaba aho ukorera. Gusimbuza ibyuma, aluminium, umuringa, titanium, ptFE nibindi bikoresho bikora neza, kunoza imikorere yimashini icyarimwe kugabanya cyane igiciro.
PEEK ifite umutekano mwiza. Ikizamini cya UL ibisubizo byibikoresho byerekana ko igipimo cya PEEK cyerekana flame retardation ni Grade V-0, nicyo cyiciro cyiza cyo gucana umuriro. PEEK yaka umuriro (ni ukuvuga, umwotsi ukorwa mugihe cyo gutwikwa guhoraho) niwo munsi wa plastiki iyo ari yo yose.
Ubushobozi bwa gaze ya PEEK (ubwinshi bwa gaze yakozwe iyo ibora ku bushyuhe bwo hejuru) nayo iri hasi.
Amateka ya PEEK
PEEK nibikoresho biri hejuru ya piramide ya plastike, kandi ibigo bike kwisi byize inzira ya polymerisation.
PEEK yatunganijwe na ICI mu myaka ya za 70. Kubera imiterere yihariye yubukorikori hamwe nuburyo bwo gutunganya, yabaye imwe mubintu byihariye bya plastiki yubuhanga.
Ikoranabuhanga rya PEEK mu Bushinwa ryatangiye mu myaka ya za 1980. Nyuma yimyaka myinshi yubushakashatsi bukomeye, kaminuza ya Jilin yateje imbere PEEK resin synthesis hamwe nuburenganzira bwumutungo wubwenge wigenga. Ntabwo imikorere yibicuruzwa igeze kurwego rwamahanga rwa PEEK gusa, ahubwo nibikoresho fatizo nibikoresho byose bishingiye mubushinwa, bigabanya neza igiciro cyumusaruro.
Kugeza ubu, Ubushinwa PEEK inganda zirakuze cyane, zifite ubuziranenge n’ibisohoka nk’abakora mu mahanga, kandi igiciro kiri hasi cyane ku isoko mpuzamahanga. Igikeneye kunozwa ni ubukire bwa PEEK.
Victrex yari ishami rya ICI yo mu Bwongereza kugeza igihe izimye.
Yabaye uruganda rwa mbere rwa PEEK kwisi.
Porogaramu ya PEEK
1. Porogaramu zo mu kirere: gusimbuza aluminium nibindi byuma kubice byindege, kubibanza bya bateri ya roketi, bolts, nuts nibigize moteri ya roketi.
.
3. Porogaramu mu mashini zitwara ibinyabiziga: gutwara ibinyabiziga, gasketi, kashe, gufunga, feri na sisitemu yo guhumeka. Nissan, NEC, Sharp, Chrysler, Moteri rusange, Audi, Airbus nabandi batangiye gukoresha ibikoresho byinshi.
4. Gusaba murwego rwubuvuzi: amagufwa yubukorikori, ishingiro ry amenyo, ibikoresho byubuvuzi bigomba gukoreshwa inshuro nyinshi.
