Imikorere Irasa no Kugereranya Hagati ya PEI na PEEK

Polyetherimide, yitwa PEI mucyongereza, Polyetherimide, ifite isura ya amber, ni ubwoko bwa amorphous thermoplastique idasanzwe ya pulasitike itangiza imiyoboro ya ether yoroheje (- Rmae Omi R -) muri molekile ndende ya polyimide.

Imiterere ya PEI

Nubwoko bwa polimide ya termoplastique, PEI irashobora guteza imbere cyane thermoplastique idahwitse no gutunganya polyimide itoroshye kwinjiza ether (- Rmurmurr R -) mumurongo wa polymer mugihe ugumana imiterere yimpeta ya polyimide.

Ibiranga PEI

Ibyiza:

Imbaraga zingana cyane, hejuru ya 110MPa.

Imbaraga zunamye cyane, hejuru ya 150MPa.

Ubushobozi buhebuje bwa termo-mashini yububiko, ubushyuhe bwo guhindura ubushyuhe burenze cyangwa bungana na 200 ℃.

Kurwanya neza kunyerera no kurwanya umunaniro.

Umuriro mwiza cyane wumuriro hamwe numwotsi muke.

Indangagaciro nziza ya dielectric na insulation.

Iterambere ryiza cyane, coefficient yo kwagura ubushyuhe.

Kurwanya ubushyuhe bwinshi, birashobora gukoreshwa kuri 170 ℃ igihe kirekire.

Irashobora kunyura muri microwave.

Ibibi:

Harimo BPA (bisphenol A), igabanya ikoreshwa ryayo mubicuruzwa bifitanye isano nimpinja.

Ingaruka zingirakamaro.

Kurwanya Alkali ni rusange, cyane cyane mubihe bishyushye.

PEEK

PEEK izina ryubumenyi polyether ether ketone ni ubwoko bwa polymer burimo ketone imwe hamwe na ether ebyiri muburyo bukuru. Nibikoresho byihariye bya polymer. PEEK ifite isura ya beige, itunganijwe neza, kunyerera no kwambara birwanya, guhangana neza n’ibikurura, kurwanya imiti myiza cyane, kurwanya hydrolysis hamwe n’amazi ashyushye cyane, imishwarara y’ubushyuhe bwinshi, ubushyuhe bwo hejuru bw’umuriro hamwe no kutagira umuriro mwiza imbere.

PEEK yakoreshejwe bwa mbere mubijyanye nindege kugirango isimbuze aluminium, titanium nibindi bikoresho byuma kugirango ikore ibice byimbere ninyuma yindege. Kuberako PEEK ifite ibintu byiza byuzuye, irashobora gusimbuza ibikoresho gakondo nkibyuma nububumbyi mubice byinshi bidasanzwe. Kurwanya ubushyuhe bwayo bwinshi, kwiyitirira amavuta, kwihanganira kwambara no kunanirwa umunaniro bituma iba imwe mumashanyarazi azwi cyane akora cyane.

Nibikoresho bya termoplastique polymer, ibiranga PEI bisa nibya PEEK, cyangwa no gusimbuza PEEK. Reka turebe itandukaniro riri hagati yombi.

Ugereranije na PEEK, imikorere yuzuye ya PEI irashimishije cyane, kandi inyungu zayo nini iri mubiciro, iyi nayo niyo mpamvu nyamukuru ituma ibikoresho bimwe na bimwe byerekana indege byatoranijwe nibikoresho bya PEI. Igiciro cyuzuye cyibice byacyo kiri munsi yicyuma, ibikoresho bya thermosetting hamwe na PEEK. Twabibutsa ko nubwo imikorere yikiguzi cya PEI iri hejuru cyane, ubushyuhe bwayo ntabwo buri hejuru.

Mu mashanyarazi ya chlorine, gucika intege bibaho byoroshye, kandi kurwanya imiti kama ntago ari byiza nkibya kabiri bya kirisiti ya polymer PEEK. Mugutunganya, niyo PEI ifite uburyo bwo gutunganya plastiki yubushakashatsi bwa termoplastique, ikenera ubushyuhe bwo hejuru.
