Ibyiza bya Polyetherimide (PEI)

Polyetherimide, cyangwa PEI, ni polimeri ikora cyane ya polymeroplastique izwiho kuba idasanzwe ya mashini, ubushyuhe, n amashanyarazi. Nimbaraga-ndende, zikomeye-aromatic polyimide hamwe nubushyuhe buhebuje. Hano haribintu bimwe byingenzi bya PEI:

Incamake Imbonerahamwe yibyingenzi byingenzi byaPolyetherimide (PEI)

1. Ibyiza byubushyuhe

•Kurwanya Ubushyuhe:
PEI ifite ubushyuhe budasanzwe bwo kugabanya ubushyuhe (HDT) hagati ya 215 ° C na 220 ° C (419 ° F - 428 ° F), butuma ishobora kwihanganira ubushyuhe bwinshi nta guhindagurika gukomeye. Ibi bituma biba byiza mubisabwa bisaba kurwanya ubushyuhe bwinshi, nko mu nganda zitwara ibinyabiziga n’ikirere.
Ikomeza imbaraga no guhagarara neza no mubushyuhe bwo hejuru.

•Ubushyuhe bw'Ibirahure (Tg):
Hamwe na Tg ya 217 ° C (423 ° F), PEI igumana ubunyangamugayo bwayo ndetse no mubushyuhe burenze kure ibikorwa bisanzwe bya plastiki.

•Coefficient yo Kwagura Ubushyuhe (CTE):
PEI ifite CTE yo hasi cyane, bivuze ko ihura nimpinduka ntoya mugihe ubushyuhe buhindagurika, bigatuma bihagarara neza kandi byizewe kubice byuzuye.

2. Ibikoresho bya mashini

•Imbaraga nyinshi no gukomera:
PEI itanga imiterere idasanzwe yubukanishi, nkimbaraga zikomeye, imbaraga zidasanzwe, hamwe nubukomezi, bikomeza kuba byiza nubwo haba hari ubushyuhe bwinshi. Ibi bituma ibera ibice byubaka muburyo busaba ibidukikije.
Imbaraga zacyo zingana kuva kuri 80 kugeza 100 MPa, ukurikije amanota.

•Ingaruka zo Kurwanya:
Mugihe PEI ikomeye muburyo bwa tekinike, ifite imbaraga zo guhangana ningaruka ugereranije nubundi buhanga bwa thermoplastique. Irashobora gutwara imitwaro minini ariko irashobora kuvunika kuvunika mubihe bimwe.

•Ikigereranyo Cyiza Cyiza:
Ibice bya PEI byerekana umutekano muke munsi yimitwaro yubukanishi, bigatuma bikenerwa no kwihanganira ibintu nkibikoresho bisobanutse neza, ibyuma bifata amashanyarazi, hamwe n’amashanyarazi.

3. Ibyiza byamashanyarazi

•Amashanyarazi meza:
PEI ni insuliranteri nziza yumuriro, itanga imbaraga za dielectric nubushobozi buke bwamashanyarazi. Ibi bituma biba byiza kubikorwa byamashanyarazi na elegitoronike, nkibibaho byumuzunguruko, umuhuza, hamwe na insulator.

•Igihombo gito cya Dielectric:
Yerekana igihombo gito cya dielectric, bigatuma gikwiranye numuyoboro mwinshi wamashanyarazi.

4. Kurwanya imiti

•Kurwanya Imiti Nziza:
PEI irwanya imiti itandukanye, harimo aside, ibishingwe, amavuta, hamwe na solde. Ariko, irashobora kwibasirwa na acide ikomeye cyangwa shingiro kubushyuhe bwinshi.
Ikora neza mubidukikije bikaze, bigatuma ikoreshwa mubisabwa mumodoka, ikirere, nubuvuzi.

•Kudakora:
PEI idakora neza hamwe na biocompatibilité ituma ikwiranye n’ibidukikije byita ku mibonano mpuzabitsina, nk’imiti n’inganda zitunganya ibiribwa.

5. Ibikoresho bya mashini ku bushyuhe buke

•Imikorere myiza yo hasi-Ubushyuhe:
PEI igumana imbaraga zayo zubukanishi hamwe nuburinganire buringaniye ndetse no mubushyuhe buke, bigatuma bikenerwa mubisabwa muri sub-zeru bitavunitse cyangwa gutakaza ubukana.

6. Ibyiza byiza

•Gukorera mu mucyo:
Kimwe mu bintu bigaragara biranga PEI ni umucyo wacyo, ufite akamaro muri optique ikoreshwa nka lens, kureba, hamwe nibikoresho bya optique aho bigaragara neza ni ngombwa.
Ifite urumuri rwohereza hejuru ya 80% kubice bito.

7. Kurwanya umuriro

•Kubura umuriro:
PEI isanzwe ifite flame-retardant, yizimya iyo ihuye numuriro kandi ntikomeza gutwika isoko yumuriro ikuweho. Yubahiriza ibipimo bitandukanye byo kurwanya flame, harimo UL 94 V-0 yo gutwika vertical.
Ibi bituma PEI ibereye mumashanyarazi nimodoka aho umutekano wumuriro wibanze.

8. Gutunganya Ibiranga

•Gutera inshinge no gukuramo:
PEI irashobora gutunganywa hifashishijwe uburyo busanzwe bwa termoplastique nko kubumba inshinge, gusohora, hamwe na thermoforming. Nyamara, kubera aho hejuru yo gushonga, ibikoresho byihariye birasabwa guhangana nubushyuhe (mubisanzwe hejuru ya 340 ° C).
PEI ifite ubukonje bwinshi kandi igabanuka ku bushyuhe bwo hejuru, bigatuma kuyitunganya bitoroshye. Nyamara, iterambere mu buhanga bwa polymer ryatumye habaho amanota-yongerewe amanota yoroshye gutunganya.

9. Kurwanya Ibidukikije

•UV Ihamye:
PEI irwanya iyangirika ryumucyo ultraviolet, ikomeza imiterere yubukanishi iyo ihuye nizuba ryizuba cyangwa amasoko yumucyo. Nyamara, irashobora kuba umuhondo mugihe hamwe na UV igihe kirekire, ishobora kugabanuka wongeyeho UV stabilisateur.

•Kurwanya Ikirere:
PEI ikora neza mubihe byo hanze, irwanya iyangirika ryikirere, ubushuhe, nibindi bintu bidukikije.

10. Biocompatibilité

•Gukoresha Ubuvuzi na Farumasi:
Bitewe nuburyo bwiza bwo kurwanya imiti, guhagarara neza, no gukorera mu mucyo, PEI ikoreshwa cyane mubikoresho byubuvuzi, gupakira imiti, nibikoresho byatewe. Yujuje ibipimo bya FDA kubisabwa mubuzima.

Porogaramu ya Polyetherimide (PEI):
PEI ikoreshwa mu nganda zitandukanye zisaba ibikoresho bikora neza, nka:
•Ikirere:Ibice byubaka, utwugarizo, hamwe na kashe bigomba kwihanganira ubushyuhe bwinshi hamwe nihungabana ryimashini.
•Imodoka:Munsi ya hood ibice nkibihuza, amazu, hamwe na sisitemu ya lisansi.
•Ibyuma bya elegitoroniki:Amashanyarazi, amashanyarazi, hamwe nibikoresho byamashanyarazi bikora cyane.
•Ubuvuzi:Ibikoresho byo kuboneza urubyaro, ibikoresho byo gusuzuma, nibikoresho byatewe.
•Inganda:Ibikoresho, ibyuma, na pompe zikora mukibazo nubushyuhe bukabije.

Umwanzuro

Polyetherimide (PEI) ni polimerike ikora cyane ya polimoplastike izwiho kuba ihagaze neza yubushyuhe, imbaraga za mashini, hamwe nuburyo bwo gukwirakwiza amashanyarazi. Ibi biranga bituma biba ibikoresho byiza byo gusaba ibisabwa mu nganda nko mu kirere, ibinyabiziga, ubuvuzi, na elegitoroniki, aho kwiringirwa mu bihe bikomeye ari ngombwa. Nubwo igiciro cyacyo kinini, PEI ihindagurika kandi iramba ituma iba ibikoresho byo guhitamo inganda zo murwego rwohejuru.
