Impahla ye-PEEK enepulasitiki yobunjiniyela esebenza kahle kakhulu ekwazi ukumelana nokushisa, ukumelana namakhemikhali, amandla emishini kanye nokuzinza kwe-dimensional

I-semi-crystalline, ipulasitiki ekhethekile yobunjiniyela be-thermoplastic eyakhiwe yi-British Imperial Chemical Industry Company (ICI) ngo-1978. Ngenxa yokuthi i-PEEK inokusebenza okuhle kakhulu okubanzi okufana nokumelana nezinga lokushisa eliphezulu, ukuzigcoba, ukumelana nokugqwala, ukunqanda ilangabi, ukumelana ne-hydrolysis, ukumelana nokugqoka kanye nokumelana nokukhathala, isetshenziswa emkhakheni wezokuvikela kazwelonke kanye nemboni yezempi, futhi kancane kancane yanda emkhakheni wezomphakathi, okuhlanganisa ukukhiqizwa kwezimboni, i-aerospace, imboni yezimoto, i-electronic kanye nemishini kagesi neyezokwelapha. Ngokuthuthukiswa okuqhubekayo kwe-PEEK synthesis kanye nobuchwepheshe bokucubungula, izinto zokusebenza eziphezulu ezitholwe ukuguqulwa kwamakhemikhali, ukuxuba kanye nokugcwalisa okuyinhlanganisela kuye kwandise inkambu yesicelo sayo. I-PEEK ifanele ukubunjwa komjovo, ukubunjwa kwe-extrusion, ukubumba i-die kanye nokuncibilika kokuphotha nezinye izindlela zokucubungula, ngokuthuthukiswa kwezindiza ezinkulu, amabhasi wesitimela, imboni yezimoto, imboni yezokuvikela yezokwelapha kanye kazwelonke, isidingo samapulasitiki onjiniyela akhethekile amelwe i-PEEK nayo. ukwanda, ikakhulukazi ekwenzeni ngcono amandla okukhiqiza nokucubungula imikhiqizo esebenza kahle kakhulu.

    Ithebula Lezinto Ezibalulekile

    I-PEEK impahla iyipulasitiki yobunjiniyela esebenza kahle kakhulu enokumelana nokushisa okuhle kakhulu, ukumelana namakhemikhali, amandla emishini kanye nokuzinza kobukhulu.

    Izici Nezindawo Zokusebenza Zezinto Zokubheka

    1. Inkambu yokushisa ephezulu: Izinto ze-PEEK zisebenza kahle ezindaweni ezishisayo futhi zingamelana namazinga okushisa afika ku-300°C. Ngakho-ke, isetshenziswa kabanzi ku-aerospace, izimoto, amakhemikhali, amandla kanye neminye imikhakha yokukhiqiza izingxenye zokushisa okuphezulu.

    2. Inkambu yokugqwala kwamakhemikhali: Impahla ye-PEEK inokumelana nokugqwala kwamakhemikhali okuhle futhi ingagcina ukusebenza okuzinzile emithonjeni yamakhemikhali ehlukahlukene njengama-acids, ama-alkali nezincibilikisi zemvelo. Ngakho-ke, isetshenziswa kabanzi ekwenzeni imishini yamakhemikhali, amapayipi, ama-valve nezinye izingxenye.

    3. Inkundla yezokwelapha: Impahla ye-PEEK inezici ze-biocompatibility nemiphumela engemihle engenabuthi, ngakho-ke isetshenziswa kabanzi ekwenziweni kwemishini yezokwelapha nezitho zokwenziwa. Isibonelo, ama-stents e-vascular, amalunga okufakelwa, i-tracheal intubation kanye neminye imikhiqizo eyenziwe ngezinto ze-PEEK isetshenziswe kabanzi emisebenzini yomtholampilo.

    4. Inkambu ye-elekthronikhi: Impahla ye-PEEK inezinto ezinhle kakhulu zokufakwa kukagesi namandla emishini, ngakho-ke isetshenziswa kabanzi ekwenzeni izinto zikagesi. Isibonelo, ama-cable bushings, izixhumi, amasokhethi kanye neminye imikhiqizo eyenziwe ngezinto ze-PEEK isetshenziswe kabanzi emasimini amandla, ukuxhumana, amakhompiyutha.

    5. Imboni yezimoto: Impahla ye-PEEK inokumelana nokushisa okuhle namandla emishini, futhi inokumelana okuhle nokungqubuzana nokumelana nokugqwala kwamakhemikhali. Ngakho-ke, isetshenziswa kabanzi ekwenzeni izingxenye zenjini yemoto, izingxenye zesistimu yokudlulisela, izingxenye zesistimu yamabhuleki.

    Izinto ze-PEEK zinezinhlobonhlobo zezinhlelo zokusebenza futhi zingahlangabezana nezidingo zokusebenza eziphezulu zezimboni nezinkambu ezahlukene. Ngokukhetha izinto ezibonakalayo nobuchwepheshe bokucubungula, izinga eliphezulu nokusebenza okuphezulu kwemikhiqizo ye-PEEK ingakhiqizwa
