Polythethide, hu ua Pei ua lus Askiv, Polythet Daws, yog ib hom kev sib cog lus yooj yim, yog ib qho kev sib cog lus yooj yim hower
Tus qauv ntawm PEI
Raws li hom ntawm thermoplastic polyimide, Pii tuaj yeem tsim kho cov neeg txom nyem ether (- rmurmurr
Cov yam ntxwv ntawm PEI
Qhov Zoo:
High tensile lub zog, saum toj no 110MPA.
High dabtsi yog muaj zog, saum toj 150mpa.
Cov kabmob zoo heev thermo-tshuab cov kabmob muaj peev xwm, thermal deformation kub ntau dua los yog sib luag rau 200 ℃.
Zoo creep tsis kam thiab nkees tsis kam.
Cov nplaim paj zoo heev retardancy thiab cov pa luam yeeb tsawg.
Dielectric thiab rwb thaiv tsev zog.
Kev nthuav dav tau zoo heev, tsawg coefficient ntawm thermal expansion.
Kev tiv thaiv cua sov siab, tuaj yeem siv ntawm 170 ℃ ntev ntev.
Nws tuaj yeem dhau ntawm microwaves.
Qhov tsis zoo:
Muaj BPA (Bisphenol a), uas txwv nws daim ntawv thov hauv cov menyuam yaus txog cov khoom lag luam.
Ceeb toom kev cuam tshuam rhiab.
Alkali tsis kam yog General, tshwj xeeb tshaj yog nyob rau hauv cov cua sov.
Qab nkaub
Peek Science lub npe Polyether ether ketone yog hom kev sib khi uas muaj ib qho Ketone hauv lub ntsiab saw qauv. Nws yog cov khoom siv polymer tshwj xeeb. Peek muaj cov tsos mob hnyav, kev siv tshuaj lom, zoo heev hluav taws xob, siab kub heev deformations kub thiab zoo sab hauv nplaim retardancy.
Peek tau siv thawj zaug hauv teb ntawm Aerospace los hloov txhuas, titanium thiab lwm cov ntaub ntawv hlau los ua sab hauv thiab sab nraud ntawm cov dav hlau. Vim tias Peek muaj cov khoom siv zoo ntxiv, nws tuaj yeem hloov cov khoom lag luam ib txwm muaj xws li hlau thiab ceramics nyob rau ntau daim teb tshwj xeeb. Nws cov kev kub siab tiv thaiv, lubrical lubrication, hnav tsis kam thiab nkees ua kom nws nyiam tshaj plaws ua rau muaj kev ua haujlwm zoo rau kev ua haujlwm.
Raws li cov khoom siv thermoplastricity polymer, cov yam ntxwv ntawm PEI zoo ib yam li cov neeg peek, lossis txawm tias qhov hloov ntawm peek. Cia peb saib qhov sib txawv ntawm ob.

Piv nrog peek, cov kev ua tau zoo ntawm Pei yog qhov zoo tshaj plaws kev ntes, thiab nws cov khoom lag luam loj tshaj plaws yog vim li cas qee cov khoom siv dav hlau tsim yog xaiv los ntawm cov ntaub ntawv sib sau ua ke. Tus nqi ntawm nws cov ntu yog qis dua li ntawm cov hlau, thickosetting sib xyaw thiab peek kev sib xyaw. Nws yuav tsum raug sau tseg tias txawm tias tus nqi ua tau zoo ntawm PEI yog qhov siab dua, nws qhov kub tsis dhau yog tsis siab heev.
Hauv chlorinated cov kuab tshuaj, kev ntxhov siab tawg tshwm sim yooj yim, thiab cov kev tawm tsam tau yooj yim, thiab cov kev tawm tsam tsis zoo li qhov ntawm ib nrab-crystalline polymer peek. Hauv kev ua tiav, txawm tias PEI muaj cov txheej txheem ntawm ib txwm thermoplastic engineering plastics, nws xav tau siab dua Melting kub.
