Yini Peek? Ukuhlaziywa okujulile kwaleli polymer ephezulu
I-Polyeatheketone (Peek) Ingabe i-polymer asebenza kahle edonsele ukunakwa okuningi ezimbonini ezahlukahlukene eminyakeni yamuva nje. Yini izakhiwo zayo ezihlukile nezinhlelo zokusebenza? Kulesi sihloko, sizowuphendula lo mbuzo ngokuningiliziwe futhi sixoxe ngezicelo zazo ezahlukahlukene ezinkambeni ezahlukahlukene.
Kuyini izinto zokubheka?
I-Peek, eyaziwa ngokuthi i-polythert ether ketone (i-polythert ether ketone), ipulasitiki yobunjiniyela be-smi-crystalline ye-armoplastic enezakhiwo ezihlukile. Kungokwe-polyaryl ether Ketone (Paek) umndeni wama-polymers, kanye nama-peek exlels ekufuneni izinhlelo zokusebenza zobunjiniyela ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, ukumelana kwamakhemikhali kanye nokuqina okushisa okuphezulu. Isakhiwo saso samangqamuzana siqukethe izindandatho ezinamakha aqinile futhi nezibopho ze-ketone eziguquguqukayo kanye nama-ketone, anikeze amandla nokuqina.
Izici ezibalulekile zezinto zokufunda
Ukumelana okushisa kakhulu okuphezulu: I-Peek inokushisa okushisa ukushisa (HDT) ka-300 ° C noma ngaphezulu, okuvumela ukuthi kugcinwe izakhiwo ezinhle kakhulu zemishini ezindaweni ezishisa kakhulu. Uma kuqhathaniswa nezinye izinto ze-thermoplastic, ukuqina kukaPeek kumazinga okushisa aphezulu kuvelele.

Amandla we-mehendi avelele: I-Peek inamandla amakhulu kakhulu, ukuqina kanye nobunzima, futhi igcina ukuqina okuhle kobukhulu ngisho nasekushiseni okuphezulu ngisho nasekushiseni okuphezulu. Ukumelana kwayo ukukhathala kuyayivumela futhi ukuthi kudlule kuzinhlelo zokusebenza ezidinga ukuvezwa isikhathi eside ekucindezelekeni kwemishini.

Ukumelana kwamakhemikhali okuhle kakhulu: I-Peek imelana kakhulu namakhemikhali ahlukahlukene, kufaka phakathi ama-acid, izisekelo, izisulu namafutha. Amandla wezinto ezifundwayo ukuze alondoloze ukwakheka kwawo kanye nezakhiwo ngezikhathi ezinde ezikhathini ezinzima zamakhemikhali ziholele ezinhlobonhlobo zezicelo kumakhemikhali, e-oyela kanye negesi.

Intuthu ephansi kanye nobuthi: I-Peek ikhiqiza amazinga aphansi kakhulu okubhema kanye nobuthi lapho ivutha, okwenza kuthandwe kakhulu ezindaweni lapho izindinganiso zokuphepha eziqinile zidingeka, njengezithuthi ze-aerospace kanye nezitimela.

Izindawo zohlelo lokusebenza lwezinto zokufunda

I-Aerospace: Ngenxa yamandla ayo aphezulu, ukumelana kwamazinga okushisa okuphezulu kanye nezakhiwo ezilula, i-Peek isetshenziswa ezinhlobonhlobo zezicelo ezinjengezinto zensimbi, zinciphisa isisindo sensimbi yendabuko, ukunciphisa isisindo semali nokwenza ngcono uphethiloli.

Amadivaysi ezokwelapha: I-Peek inokuthambekela okuhle futhi ivame ukusetshenziswa ekwenziweni kwezimila zamathambo, imishini yamazinyo namathuluzi okuhlinza. Uma kuqhathaniswa nezimila zensimbi zendabuko, ukufakwa okwenziwe ngezinto ezi-Peek kune-radiopacity engcono kanye nokusabela okumbalwa komzimba.

I-Electrical ne-Electronics: Izakhiwo ezivimbela ukushisa ezivimbela ukushisa kanye nogesi zenza ilungele ukukhiqizwa kwezixhumi zikagesi eziphezulu, izakhi ezifaka ukufakwa, kanye nemishini yokukhiqiza i-semiconductor.
Izithuthi: Embonini yezimoto, i-Peek isetshenziselwa ukukhiqiza izakhi zenjini, ama-bearings, izimpawu zokwenziwa, njll. Lezi zingxenye zidinga impilo ende kanye nokuthembela emazingeni okushisa aphezulu nasengcindezini. Lezi zingxenye zidinga impilo ende nokwethembeka emazingeni okushisa aphezulu nezingcindezi, kanye nezinto zokwakha ezihlanganayo zihlangabezana nalezi zidingo.

Amathemba esikhathi esizayo sezinto zokufunda

Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, uhla lwezicelo ze-Peek luzokhula ngokuqhubekayo. Ikakhulu emkhakheni wokukhiqiza okuphelo kakhulu, ubuchwepheshe bezokwelapha kanye nentuthuko esimeme, bheka ngezinzuzo zayo zokusebenza ezihlukile, kuzodlala indima ebaluleke kakhulu. Kwamabhizinisi kanye nezikhungo zocwaningo, ukuqonda okujulile okujulile kwalokhu kubhekwa futhi izinhlelo zalo ezihlobene kuzosiza ukubamba amathuba emakethe azayo.
Njengezinto eziphakeme ze-polymer, i-Peek ihamba kancane kancane iba yingxenye ebaluleke kakhulu embonini yanamuhla ngenxa yokusebenza kwayo okuhle kanye nohlu olubanzi lwamathemba wohlelo lokusebenza. Uma usacabanga ukuthi yini ebheke phezulu, ngethemba ukuthi le ndatshana ikunikeze ngempendulo ecacile nephelele.
