PEEK yog dab tsi?
Polyether ether ketone(PEEK) yog cov khoom siv thermoplastic aromatic polymer. Nws yog ib hom tshwj xeeb engineering yas nrog kev ua tau zoo heev, tshwj xeeb tshaj yog qhia super muaj zog kub tsis kam, kev sib txhuam tsis kam thiab qhov ntev stability. Nws yog dav siv hauv aerospace, tub rog, tsheb, tshuaj thiab lwm yam.
Basic PEEK kev ua tau zoo
PEEK muaj lub zog txhua yam, kub tsis kam, cuam tshuam tsis kam, nplaim hluav taws, acid thiab alkali tsis kam, hydrolysis tsis kam, abrasion tsis kam, qaug zog tiv thaiv, hluav taws xob tiv thaiv thiab hluav taws xob zoo.
Nws yog qib siab tshaj plaws ntawm cov cua sov ua haujlwm hauv cov yas tshwj xeeb engineering.
Kev pabcuam ntev kub tuaj yeem yog los ntawm -100 ℃ to 260 ℃.
PEEK yas raw cov ntaub ntawv muaj superior seem stability yam ntxwv. Ib puag ncig nrog qhov kub thiab txias hloov pauv muaj qhov cuam tshuam me ntsis ntawm qhov loj ntawm PEEK qhov chaw, thiab PEEK txhaj tshuaj molding shrinkage tus nqi me me, uas ua rau qhov tseeb qhov tseeb ntawm PEEK qhov ntau dua li ntawm cov yas dav dav, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua. high-dimensional raug nyob rau hauv kev ua hauj lwm tej yam kev mob.
PEEK muaj cov yam ntxwv tseem ceeb ntawm cov cua kub-resistant hydrolysis.
Nyob rau hauv ib puag ncig ntawm kub thiab high humidity dej nqus dej yog tsawg heev, zoo ib yam li nylon thiab lwm yam yas vim yog dej nqus thiab qhov luaj li cas ntawm qhov pom tseeb hloov.
PEEK muaj cov tawv tawv zoo heev thiab qaug zog, piv rau cov hlau, thiab tuaj yeem siv tau ntev hauv kev xav tau kev ua haujlwm. Txhawm rau hloov cov hlau, txhuas, tooj liab, titanium, ptFE thiab lwm yam ntaub ntawv ua tau zoo, txhim kho kev ua haujlwm ntawm lub tshuab tib lub sijhawm txo tus nqi zoo heev.
PEEK muaj kev ruaj ntseg zoo. UL cov qhabnias ntawm cov khoom siv qhia tau tias PEEK cov nplaim hluav taws kub nyhiab yog Qib V-0, uas yog qib zoo ntawm cov nplaim hluav taws. PEEK's combustibility (piv txwv li, cov pa luam yeeb tsim tawm thaum lub sij hawm sib txuas tas li) yog qhov qis tshaj ntawm cov yas.
PEEK cov roj tsis muaj peev xwm (qhov concentration ntawm cov roj tsim thaum decomposed ntawm qhov kub siab) kuj qis.
PEEK's history
PEEK yog cov khoom siv nyob rau sab saum toj ntawm cov yas pyramid, thiab ob peb lub tuam txhab hauv ntiaj teb tau paub txog cov txheej txheem polymerization.
PEEK tau tsim los ntawm ICI hauv xyoo 1970s. Vim nws cov khoom siv kho tshuab zoo heev thiab cov khoom siv ua haujlwm, nws tau los ua ib qho tshwj xeeb tshaj plaws engineering plastics.
Tuam Tshoj tus PEEK tshuab tau pib hauv 1980s. Tom qab xyoo ntawm kev tshawb fawb nyuaj, Jilin University tau tsim cov txheej txheem PEEK resin synthesis nrog kev ywj pheej ntawm cov cuab yeej cuab tam. Tsis tsuas yog cov khoom lag luam tau mus txog qib PEEK txawv teb chaws, tab sis kuj yog cov khoom siv raw thiab cov khoom siv tag nrho raws li hauv Suav teb, txo cov nqi tsim khoom.
Tam sim no, Tuam Tshoj txoj kev lag luam PEEK yog tus paub tab, nrog cov khoom zoo tib yam thiab cov khoom lag luam tawm txawv teb chaws, thiab tus nqi qis dua li kev lag luam thoob ntiaj teb. Dab tsi yuav tsum tau txhim kho yog PEEK ntau yam kev nplua nuj.
Victrex yog ib lub koom haum ntawm Britain's ICI mus txog thaum nws tau tawm mus.
Nws tau los ua lub ntiaj teb thawj PEEK chaw tsim khoom.
Daim ntawv thov ntawm PEEK
1. Aerospace daim ntaub ntawv: hloov cov txhuas thiab lwm yam hlau rau aircraft qhov chaw, rau foob pob ua ntxaij roj teeb qhov, bolts, ceev thiab cov khoom rau foob pob ua ntxaij cav.
2. Daim ntawv thov nyob rau hauv hluav taws xob teb: rwb thaiv tsev zaj duab xis, connector, luam Circuit Court board, siab kub connector, integrated circuit, cable coil skeleton, rwb thaiv tsev txheej, thiab lwm yam.
3. Kev siv hauv cov tshuab tsheb: tsheb bearings, gaskets, seals, clutches, brakes thiab cua txias tshuab. Nissan, NEC, Sharp, Chrysler, GENERAL Motors, Audi, Airbus thiab lwm yam tau pib siv cov khoom siv ntau heev.
4. Kev siv hauv kev kho mob: pob txha pob txha, cov hniav cog hniav hauv paus, cov khoom siv kho mob uas yuav tsum tau siv ntau zaus.
