I-polyether ether ketone resin (i-polyetheretherketone, ebizwa ngokuthi i-PEEK resin) iwuhlobo lwe-thermoplastic yokushisa ephezulu enezinga lokushisa eliphezulu lokushintsha kwengilazi (143C) kanye nephoyinti elincibilikayo (334C). Izinga lokushisa lokushintsha kwe-thermal lomthwalo liphezulu njenge-316C (30% i-glass fibre noma i-carbon fiber eqinisiwe). Ingasetshenziswa isikhathi eside ku-250C. Uma kuqhathaniswa namanye amapulasitiki amelana nezinga lokushisa eliphezulu anjenge-pi, pps, ptfe, ppo, njll., umkhawulo ongaphezulu wokushisa kwesevisi udlula cishe ku-50 ℃.
Ifomula yesakhiwo imi kanje:
Izakhiwo
I-PEEK resin ayinakho nje ukumelana nokushisa okungcono kunamanye amapulasitiki amelana nokushisa okuphezulu, kodwa futhi inamandla aphezulu, i-modulus ephezulu, ukuqina kokuphuka okuphezulu kanye nokungaguquki kosayizi omuhle.
I-PEEK resin ingagcina amandla aphezulu ekushiseni okuphezulu, futhi amandla ayo ama-zigzag afika ku-24mpa ku-200C, futhi amandla ayo aguquguqukayo namandla okucindezela kuseyi-12 ~ 13mpa ku-250C.
I-PEEK resin inokuqina okuphezulu, ukungaguquki kosayizi omuhle kanye ne-coefficient encane yokunwetshwa komugqa, esondelene kakhulu naleyo ye-aluminium.
Inokumelana okuhle kwamakhemikhali. Phakathi kwamakhemikhali, i-sulfuric acid egxilile kuphela engakwazi ukuyincibilikisa noma ukuyichoboza. Ukumelana nokugqwala kwayo kufana nokwensimbi ye-nickel. Ngesikhathi esifanayo, inokuncipha komlilo futhi ikhipha intuthu encane namagesi anobuthi ngaphansi kwelangabi. Ukumelana nemisebe enamandla.
I-PEEK resin inokuqina okuhle kanye nokumelana okuhle nokubola ekushintsheni ingcindezi, okuyiyona evelele kakhulu kuwo wonke amapulasitiki, afana nezinto ze-alloy.
I-PEEK resin inezici ezivelele ze-tribological, ukumelana okuhle kakhulu kokuslayida kokugqoka kanye nokumelana nokugqoka okukhathazayo, ikakhulukazi ukumelana nokugqoka okuphezulu kanye ne-coefficient ephansi yokungqubuzana ku-250C.
I-PEEK resin inezinzuzo ze-extrusion elula kanye nokubumba komjovo, umsebenzi omuhle kakhulu wokucubungula nokusebenza kahle kokubumba okuphezulu.
I-PEEK futhi inemisebenzi emihle kakhulu njengokuzithambisa okuhle, ukucutshungulwa kalula, ukwahlukanisa okungaguquki, ukumelana ne-hydrolysis nokunye.
Izinhlelo zokusebenza
Izinto zikagesi nezikagesi
Emkhakheni wezinto zikagesi nezinto zikagesi, i-PEEK resin inomsebenzi omuhle kagesi futhi iyisivikeli esihle sikagesi. Ingakwazi ukugcina ukufakwa kukagesi okuhle kakhulu ngaphansi kwezimo ezinzima zokusebenza ezifana nezinga lokushisa eliphezulu, amandla kagesi aphezulu kanye nomswakama ophezulu. Ngakho-ke, inkambu yezinto zikagesi kanye nezinto zikagesi isiye yaba isigaba sesibili esikhulu kunazo zonke sohlelo lwe-PEEK resin.
Embonini ye-semiconductor, i-PEEK resin ivame ukusetshenziselwa ukwenza abathwali be-wafer, ama-diaphragms afaka i-electronic insulating kanye nazo zonke izinhlobo zemishini yokuxhuma, kanye namafilimu e-wafercarrier insulating, izixhumi, amabhodi wesekethe aphrintiwe, izixhumi zokushisa okuphezulu nokunye.
Ngaphezu kwalokho, i-PEEK resin ingasetshenziswa futhi ezintweni zokuhamba zamanzi ahlanzekile kanye nempahla yokugcina, njengamapayipi, ama-valve, amaphampu nama-accumulators.
Njengamanje, i-PEEK resin nayo iyasetshenziswa ekukhiqizeni okuhlanganisiwe
Ukwelashwa kwezokwelapha
Emkhakheni wezokwelapha, ngaphezu kwemishini yokuhlinza neyamazinyo edinga ukuvala inzalo okuphezulu kanye nezikhathi eziningana zokusetshenziswa, nokwakhiwa kwezinye izinsimbi zezokwelapha ezihlangene, ukusetshenziswa okubaluleke kakhulu kwe-PEEK resin kuyithambo lokwenziwa elingangena esikhundleni sokwakhiwa kwensimbi. Ithambo lokwenziwa elenziwe nge-PEEK resin alinayo nje kuphela izinzuzo zesisindo esilula, ukungabi nobuthi kanye nokumelana nokugqwala okuqinile, kodwa futhi into eseduze kakhulu nethambo lomuntu epulasitiki, engaxhunywa nomzimba ngokwemvelo. ngakho-ke, ukusebenzisa i-PEEK resin esikhundleni sensimbi ukwenza ithambo lomuntu kuwukusetshenziswa okuyinhloko emkhakheni wezokwelapha, okunokubaluleka okude nokubaluleka.
Imboni yemishini
Embonini yemishini, i-PEEK resin ivame ukusetshenziselwa ukwakha amapuleti e-valve yomshini oqinisayo, izindandatho zepiston, izimpawu kanye nemizimba yephampu yamakhemikhali ehlukahlukene kanye nezingxenye zamavalvu. I-impeller yepompo ye-swirl yakhiwe ngale resin esikhundleni sensimbi engagqwali. ngaphezu kwalokho, i-PEEK resin ihlangabezana nezidingo zokucaciswa kwezinto zokusebenza zeqembu lamapayipi, futhi zonke izinhlobo zokunamathela zisengasetshenziselwa ukubopha ezingeni lokushisa eliphezulu, ngakho izixhumi zesimanje zizoba enye imakethe engaba khona.
Imoto
Izinto ze-PEEK ze-polymeric zingakwazi ukufaka esikhundleni sensimbi ngempumelelo, izinto ezihlanganisiwe zendabuko kanye namanye amapulasitiki ngenxa yokuqina kwawo okungavamile, inertia yamakhemikhali kanye nezindawo zokubuyiswa komlilo, futhi kulula ukucutshungulwa zibe izingxenye ezinokubekezelela okuncane kakhulu. I-PEEK inezinzuzo zokukhanya okuthile kwamandla adonsela phansi, i-anti-corrosion kanye nokumelana nezinga lokushisa.
Izinto ze-PEEK ze-polymeric zigunyazwe ngokusemthethweni abakhiqizi bezindiza abambalwa, kodwa futhi bahlangabezana nezidingo zokuhlinzekwa kwemikhiqizo evamile yezempi, i-PEEK resin ingenza izingxenye zezindiza ezihlukahlukene-uhlelo lokusebenza emkhakheni we-aerospace lukhule ngokushesha.
I-Aerospace
Emkhathini, i-PEEK resin ingathatha indawo ye-aluminium nezinye izinto zensimbi ukuze yenze zonke izinhlobo zezingxenye zendiza, ilawule umsebenzi wayo omuhle kakhulu wokunqanda ilangabi, futhi ingasetshenziswa ukwenza izingxenye zangaphakathi zendiza ukuze zimise indiza uma kwenzeka kuba nengozi yomlilo.
Amandla omthombo wamafutha
Esicini samandla omthombo wamandla kaphethiloli, i-PEEK resin imelana nezinga lokushisa eliphezulu, akulula ukuyikhipha emanzini futhi imelana nemisebe, ngakho uhlaka lwekhoyili yentambo nekhebula olwakhiwe ngalo lusetshenziswe ngempumelelo ezimbonini zamandla enuzi.
Ukuhlola i-petroleum.
Embonini yokuhlola nokuxhashazwa kwe-petroleum, ingasetshenziswa ukwenza ama-probe obukhulu obukhethekile bejometri ethintwa imishini yezimayini.
Izinto zokumboza
Esicini sokumboza, insimbi ene-insulation enhle, ukumelana nokugqwala okuqinile, ukumelana nokushisa nokumelana namanzi kungatholakala ngokumboza i-powder coating ye-PEEK resin ensimbi.
Imikhiqizo yokumboza i-PEEK powder isetshenziswa kabanzi kumakhemikhali e-anti-corrosion, izinto zikagesi zasendlini, i-electronics, imishini kanye neminye imikhakha.
Ngaphezu kwalokho, i-PEEK resin ingaphinda isetshenziselwe ukwenza amakholomu apakishiwe kanye nokuxhuma amashubhu acwebe kakhulu amathuluzi okuhlaziya i-chromatographic ewuketshezi.
