Chii chinonzi PEEK? Kuongorora kwakadzama kweiyi yepamusoro-inoshanda polymer
Polyetheretherketone (PEEK) imhando yepamusoro-soro yepolymer zvinhu zvakakwezva vanhu vakawanda mumaindasitiri akasiyana mumakore apfuura.Chii chinonzi PEEK? Ndeapi akasiyana ezvivakwa uye mashandisiro ayo? Muchikamu chino, tichapindura mubvunzo uyu zvakadzama uye kukurukura huwandu hwayo hwakasiyana hwekushandisa munzvimbo dzakasiyana siyana.
Chii chinonzi PEEK zvinhu?
PEEK, inozivikanwa sePolyether Ether Ketone (Polyether Ether Ketone), iri semi-crystalline thermoplastic engineering plastiki ine zvinhu zvakasiyana. Ndeyemhuri yepolyaryl ether ketone (PAEK) yemapolymers, uye PEEK inokunda mukudiwa kweinjiniya zvikumbiro nekuda kwekunaka kwayo kwemuchina, kuramba kwemakemikari uye kugadzikana kwakanyanya kwekushisa. Chimiro chayo chemorekuru chine maringi anonhuhwirira akaomeswa uye anochinjika ether uye ketone bond, achiipa zvese simba uye kuoma.
Zvinhu zvakakosha zvePEEK zvinhu
Yakanyanya kunaka-yepamusoro-tembiricha kuramba: PEEK ine tembiricha yekupisa (HDT) ye300 ° C kana kupfuura, iyo inoibvumira kuchengetedza yakanakisa mechanicha zvimiro munzvimbo dzepamusoro-tembiricha. Kuenzaniswa nezvimwe zvinhu zve thermoplastic, kugadzikana kwePEEK pakupisa kwakanyanya kwakanakisa.

Yakasarudzika simba remuchina: PEEK ine yakanyanya kusimba simba, kusimba uye kuoma, uye inochengetedza yakanaka dimensional kugadzikana kunyangwe pakupisa kwakanyanya. Kuramba kwayo kuneta kunobvumirawo kuti ibudirire mumashandisirwo ayo anoda kuratidzwa kwenguva refu kune mechanical stress.

Yakanakisa makemikari kuramba: PEEK inopikisa zvakanyanya kune akasiyana siyana emakemikari, anosanganisira acids, mabhesi, zvinonyungudutsa nemafuta. Kugona kwezvinhu zvePEEK kuchengetedza chimiro chazvo uye zvivakwa kwenguva yakareba munzvimbo dzakaomarara dzemakemikari zvakakonzera kuwanda kwekushandisa mumakemikari, oiri uye gasi maindasitiri.

Utsi hwakaderera uye muchetura: PEEK inogadzira yakaderera zvakanyanya ehutsi uye chepfu kana yapiswa, izvo zvinoita kuti ive yakakurumbira munzvimbo dzinodiwa zvakanyanya kuchengetedza zviyero, senge aerospace uye njanji.

Nzvimbo dzekushandisa dzePEEK zvinhu

Aerospace: Nekuda kwesimba rayo rakakura, kupisa kwekushisa kwepamusoro uye zvimiro zvisingaremi, PEEK inoshandiswa mumhando dzakasiyana siyana senge mukati yendege, zvikamu zveinjini uye zvibatanidza zvemagetsi, kutsiva zvigadzirwa zvesimbi zvechinyakare, kuderedza huremu hwese uye kuvandudza kushanda kwemafuta.

Zvishandiso zvekurapa: PEEK ine biocompatibility yakanaka uye inowanzoshandiswa mukugadzirwa kwemapfupa emapfupa, midziyo yemazino uye maturusi ekuvhiya. Kuenzaniswa neyekare simbi inodyarwa, ma implants akagadzirwa nePEEK zvinhu ane radiopacity iri nani uye mashoma allergic reactions.

Magetsi neMagetsi: PEEK isingadziviriri kupisa uye inodzivirira magetsi zvinhu zvinoita kuti ive yakanakira kugadzirwa kwepamusoro-soro majoini emagetsi, zvinhu zvinodzivirira, uye semiconductor yekugadzira michina.
Motokari: Mumotokari yemotokari, PEEK inoshandiswa kugadzira zvikamu zvejini, mabheji, zvisimbiso, nezvimwewo. Izvi zvikamu zvinoda hupenyu hurefu uye kuvimbika pakupisa kwepamusoro uye kudzvinyirira. Izvi zvikamu zvinoda hupenyu hurefu uye kuvimbika pakupisa kwakanyanya uye kumanikidzwa, uye PEEK zvinhu zvinosangana nezvinodiwa izvi.

Ramangwana Tarisiro yePEEK Zvishandiso

Sezvo tekinoroji ichienderera mberi, huwandu hwemashandisirwo ePEEK huchawedzera. Kunyanya mumunda wekugadzirwa kwepamusoro, tekinoroji yekurapa uye kusimudzira kwakasimba, PEEK ine yakasarudzika mabhenefiti ekuita, ichaita basa rinowedzera kukosha. Kune emabhizinesi uye masangano ekutsvagisa, kunzwisisa kwakadzama kwePEEK uye mashandisiro ayo ane hukama kuchabatsira kubata mikana yemusika mune ramangwana.
Seyepamusoro-inoita polymer zvinhu, PEEK iri kuita zvishoma nezvishoma chikamu chakakosha cheindasitiri yemazuva ano nekuda kwekuita kwayo kwakanaka uye kuwanda kwetarisiro yekushandisa. Kana uchiri kufunga kuti PEEK chii, ndinovimba chinyorwa ichi chakupa mhinduro yakajeka uye yakazara.
