Yini i-PEEK? Ukuhlaziywa okujulile kwale polymer esebenza kahle kakhulu
I-Polyetheretherketone (PEEK) iwumsebenzi we-polymer osebenza kahle odonse ukunaka okuningi ezimbonini ezihlukahlukene eminyakeni yamuva.Iyini i-PEEK? Yiziphi izakhiwo zayo eziyingqayizivele kanye nezicelo? Kulesi sihloko, sizophendula lo mbuzo ngokuningiliziwe futhi sixoxe ngezinhlobonhlobo zezinhlelo zokusebenza emikhakheni ehlukahlukene.
Iyini impahla ye-PEEK?
I-PEEK, eyaziwa ngokuthi i-Polyether Ether Ketone (I-Polyether Ether Ketone), iyipulasitiki yobunjiniyela be-thermoplastic eyingxenye yecrystalline enezindawo eziyingqayizivele. Ingowomndeni we-polyaryl ether ketone (PAEK) wama-polymers, futhi i-PEEK ihamba phambili ekufuneni izicelo zobunjiniyela ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, ukumelana namakhemikhali kanye nokuzinza okuphezulu kwezinga lokushisa. Isakhiwo sayo samangqamuzana siqukethe izindandatho ezinephunga elimnandi namabhondi e-ether aguquguqukayo, okukunikeza kokubili amandla nokuqina.
Izici ezibalulekile zezinto ze-PEEK
Ukumelana nezinga lokushisa eliphezulu okuhle kakhulu: I-PEEK inezinga lokushisa lokushintsha ukushisa (HDT) elingu-300 ° C noma ngaphezulu, elivumela ukuthi igcine izakhiwo ezinhle kakhulu zemishini ezindaweni ezinezinga lokushisa eliphezulu. Uma kuqhathaniswa nezinye izinto ze-thermoplastic, ukuzinza kwe-PEEK emazingeni okushisa aphezulu kuvelele.

Amandla emishini avelele: I-PEEK inamandla aqine kakhulu wokunyakaziswa, ukuqina kanye nokuqina, futhi igcina ukuqina okuhle kobukhulu ngisho nakumazinga okushisa aphezulu. Ukumelana nokukhathala kwayo nakho kuyivumela ukuthi iphumelele ezinhlelweni ezidinga ukuchayeka isikhathi eside ekucindezelekeni kwemishini.

Ukumelana namakhemikhali okuhle kakhulu: I-PEEK imelana kakhulu nezinhlobonhlobo zamakhemikhali, kufaka phakathi ama-asidi, izisekelo, izinyibilikisi namafutha. Ikhono lezinto ze-PEEK zokugcina ukwakheka kanye nezakhiwo zazo isikhathi eside ezindaweni zamakhemikhali ezinonya kuye kwaholela ekusetshenzisweni okubanzi kwezimboni zamakhemikhali, zikawoyela negesi.

Intuthu ephansi nobuthi: I-PEEK ikhiqiza amazinga aphansi kakhulu entuthu nobuthi lapho ishiswa, okwenza idume kakhulu ezindaweni lapho kudingeka khona izindinganiso eziqinile zokuphepha, njenge-aerospace kanye nezokuthutha zikaloliwe.

Izindawo zokufaka izicelo zezinto ze-PEEK

I-Aerospace: Ngenxa yamandla ayo aphezulu, ukumelana nokushisa okuphezulu kanye nezakhiwo ezingasindi, i-PEEK isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezifana nengaphakathi lendiza, izingxenye zenjini nezixhumi zikagesi, esikhundleni sezinto zensimbi zendabuko, ukunciphisa isisindo sonke kanye nokuthuthukisa ukusebenza kahle kukaphethiloli.

Imishini yezokwelapha: I-PEEK ine-biocompatibility enhle futhi ivame ukusetshenziswa ekwenzeni izimila zamathambo, imishini yamazinyo namathuluzi okuhlinza. Uma kuqhathaniswa nezifakelo zensimbi zendabuko, izimila ezenziwe ngezinto ze-PEEK zine-radiopacity engcono kanye nokungezwani nokungezwani okumbalwa.

Ezogesi kanye Nezogesi: Izakhiwo ze-PEEK ezikwazi ukumelana nokushisa nezivimbela ugesi ziyenza ifaneleke ukwakhiwa kwezixhumi zikagesi ezisebenza kahle kakhulu, izinto ezivikelayo, kanye nemishini yokukhiqiza isemiconductor.
Izimoto: Embonini yezimoto, i-PEEK isetshenziselwa ukukhiqiza izingxenye zenjini, ama-bearing, ama-seal, njll. Lezi zingxenye zidinga impilo ende nokuthembeka emazingeni okushisa aphezulu nezingcindezi. Lezi zingxenye zidinga impilo ende nokuthembeka emazingeni okushisa aphezulu nezingcindezi, futhi izinto ze-PEEK zihlangabezana nalezi zidingo.

Amathemba Ekusasa Lezinto Ze-PEEK

Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ububanzi bezinhlelo zokusebenza ze-PEEK buzokhula ngokuqhubekayo. Ikakhulukazi emkhakheni wokukhiqiza okuphezulu, ubuchwepheshe bezokwelapha kanye nentuthuko esimeme, i-PEEK enezinzuzo zayo eziyingqayizivele zokusebenza, izodlala indima ebaluleke kakhulu. Kumabhizinisi nezikhungo zocwaningo, ukuqonda okujulile kokuthi iyini i-PEEK kanye nezinhlelo zokusebenza zayo ezihlobene kuzosiza ukubamba amathuba emakethe esikhathi esizayo.
Njengempahla ye-polymer esebenza kahle kakhulu, i-PEEK kancane kancane iba yingxenye ebalulekile yemboni yesimanje ngenxa yokusebenza kwayo okuhle kakhulu kanye nohlu olubanzi lwamathemba ohlelo. Uma usacabanga ukuthi iyini i-PEEK, ngethemba ukuthi lesi sihloko sikunikeze impendulo ecacile nephelele.
