Polyether ether ketone resin (polyetheretherketone, yotchedwa PEEK resin) ndi mtundu wa kutentha kwambiri kwa thermoplastic wokhala ndi kutentha kwa magalasi apamwamba (143C) ndi malo osungunuka (334C). The katundu matenthedwe kutentha kutentha ndi okwera 316C (30% galasi CHIKWANGWANI kapena mpweya CHIKWANGWANI kulimbikitsa). Itha kugwiritsidwa ntchito kwa nthawi yayitali pa 250C. Poyerekeza ndi mapulasitiki ena apamwamba kutentha kugonjetsedwa monga pi, pps, ptfe, ppo, etc., malire chapamwamba cha kutentha utumiki kuposa 50 ℃.
The structural formula ndi motere:
Katundu
PEEK resin sikuti imangokhala ndi kukana kutentha kwambiri kuposa mapulasitiki ena okwera kwambiri, komanso imakhala ndi mphamvu zambiri, modulus yayikulu, kulimba kwapang'onopang'ono komanso kusasinthasintha kwabwino.
PEEK utomoni ukhoza kukhalabe ndi mphamvu yapamwamba pa kutentha kwakukulu, ndipo mphamvu yake ya zigzag imafika ku 24mpa pa 200C, ndipo mphamvu yake yosinthasintha ndi mphamvu yopondereza idakali 12 ~ 13mpa pa 250C.
PEEK resin imakhala yolimba kwambiri, kukula kwake kosasinthika komanso kocheperako kakang'ono kakukulitsa, komwe kuli pafupi kwambiri ndi aluminium.
Ili ndi kukana kwambiri kwamankhwala. Pakati pa mankhwala, sulfuric acid yokhayo imatha kusungunuka kapena kuiphwanya. Kukana kwake kwa dzimbiri kumafanana ndi chitsulo cha nickel. Panthawi imodzimodziyo, imakhala ndi mphamvu yowonongeka ndipo imatulutsa utsi wochepa ndi mpweya wapoizoni pansi pa malawi. Kukana kwamphamvu kwa radiation.
Utoto wa PEEK uli ndi kulimba kwabwino komanso kuwonongeka kwabwino kukana kupsinjika kosinthika, komwe kuli kopambana kuposa mapulasitiki onse, omwe amafanana ndi zida za alloy.
Utoto wa PEEK uli ndi mawonekedwe apamwamba kwambiri a tribological, kukana kwamphamvu kotsetsereka komanso kukana kuvala kovutirapo, makamaka kukana kuvala kwambiri komanso kugundana kochepa pa 250C.
PEEK utomoni uli ndi ubwino wa extrusion yosavuta ndi jekeseni akamaumba, ntchito yabwino processing ndi mkulu akamaumba bwino.
PEEK ilinso ndi ntchito zabwino kwambiri monga kudzipangira bwino, kukonza kosavuta, kutchinjiriza kosalekeza, kukana kwa hydrolysis ndi zina zotero.
Mapulogalamu
Zida zamagetsi ndi zamagetsi
Pazinthu zamagetsi ndi zida zamagetsi, PEEK resin imakhala ndi ntchito yabwino yamagetsi ndipo ndi insulator yabwino yamagetsi. Imatha kukhalabe ndi chitetezo chabwino kwambiri chamagetsi pansi pamikhalidwe yovuta kwambiri yogwirira ntchito monga kutentha kwambiri, magetsi okwera komanso chinyezi chambiri. Chifukwa chake, gawo lamagetsi ndi zida zamagetsi pang'onopang'ono lakhala gulu lachiwiri lalikulu kwambiri la PEEK resin.
M'makampani a semiconductor, utomoni wa PEEK umagwiritsidwa ntchito popanga zonyamulira zopyapyala, ma diaphragms otsekereza zamagetsi ndi mitundu yonse ya zida zolumikizira, komanso mafilimu oteteza wafercarrier, zolumikizira, matabwa osindikizidwa, zolumikizira kutentha ndi zina zotero.
Kuphatikiza apo, utomoni wa PEEK utha kugwiritsidwanso ntchito pamayendedwe amadzi oyera kwambiri komanso zida zosungira, monga mapaipi, mavavu, mapampu ndi ma accumulators.
Pakalipano, PEEK resin ikugwiritsidwanso ntchito popanga Integrated
Chithandizo chamankhwala
Pazachipatala, kuwonjezera pa opaleshoni ndi zida zamano zomwe zimafuna kutsekereza kwambiri komanso kangapo kogwiritsa ntchito, komanso kupanga zida zina zamankhwala zophatikizika, ntchito yofunika kwambiri ya PEEK resin ndi fupa lopanga lomwe lingalowe m'malo mwa chitsulo. Fupa lochita kupanga lopangidwa ndi utomoni wa PEEK sikuti lili ndi ubwino wolemera pang'ono, wopanda poizoni komanso kukana kwamphamvu kwa dzimbiri, komanso zinthu zapafupi kwambiri ndi fupa la munthu mu pulasitiki, zomwe zimatha kulumikizidwa ndi thupi mwakuthupi. Choncho, kugwiritsa ntchito PEEK resin m'malo mwachitsulo kupanga fupa laumunthu ndilofunika kwambiri pachipatala, lomwe liri ndi tanthauzo lalikulu komanso lamtengo wapatali.
Makampani opanga makina
M'makampani amakina, utomoni wa PEEK nthawi zambiri umagwiritsidwa ntchito popanga ma valve omangitsa a makina, mphete za pistoni, zisindikizo ndi matupi amtundu wapampopi wamankhwala ndi zida za valve. Chotsitsa cha pampu yozungulira chimamangidwa ndi utomoni uwu m'malo mwa chitsulo chosapanga dzimbiri. Komanso, PEEK utomoni amakwaniritsa zofunikira za chitoliro gulu workpiece zipangizo, ndi mitundu yonse ya zomatira angagwiritsidwe ntchito kugwirizana pa kutentha kwambiri, kotero zolumikizira zamakono adzakhala msika wina angathe.
Galimoto
PEEK polymeric zida zimatha m'malo mwa zitsulo, zida zophatikizika zachikhalidwe ndi mapulasitiki ena chifukwa champhamvu kwambiri, inertia yamankhwala komanso zoletsa moto, ndipo ndizosavuta kusinthidwa kukhala magawo omwe ali ndi zololera zazing'ono kwambiri. PEEK ili ndi ubwino wa mphamvu yokoka yowala, anti-corrosion ndi kukana kutentha.
PEEK polymeric zida zavomerezedwa mwalamulo ndi opanga ndege angapo, komanso zimakwaniritsa zofunikira pakuperekedwa kwa zida zankhondo zankhondo, utomoni wa PEEK utha kupanga zida zingapo zandege-kugwiritsa ntchito m'munda wamlengalenga wakula mwachangu.
Zamlengalenga
M'mlengalenga, PEEK utomoni ukhoza m'malo mwa aluminiyamu ndi zipangizo zina zachitsulo kupanga mitundu yonse ya ziwalo za ndege, kulamulira ntchito yake yabwino kwambiri yoletsa moto, ndipo ingagwiritsidwe ntchito kupanga ziwalo zamkati za ndege kuti zifike ndegeyo ngati pangakhale ngozi ya moto.
Mphamvu yamafuta
Pankhani ya mphamvu yamagetsi, utomoni wa PEEK umalimbana ndi kutentha kwambiri, sikophweka kusungunuka komanso kugonjetsedwa ndi ma radiation, kotero kuti waya ndi chingwe cha coil chimamangidwa ndi icho chagwiritsidwa ntchito bwino m'mafakitale amagetsi a nyukiliya.
Kufufuza kwa petroleum.
M'makampani ofufuza ndi kugwiritsa ntchito mafuta a petroleum, atha kugwiritsidwa ntchito kupanga ma probe amitundu yapadera ya geometric yomwe imakhudzidwa ndi makina amigodi.
zokutira zakuthupi
Pankhani ya zokutira, zitsulo zokhala ndi kutchinjiriza bwino, kukana kwamphamvu kwa dzimbiri, kukana kutentha ndi kukana madzi zitha kupezeka pophimba zokutira zaufa za PEEK resin pazitsulo.
PEEK zopangira ufa zimagwiritsidwa ntchito kwambiri polimbana ndi dzimbiri, zida zapakhomo, zamagetsi, makina ndi zina.
Kuphatikiza apo, utomoni wa PEEK utha kugwiritsidwanso ntchito kupanga mizati yodzaza ndi kulumikiza machubu apamwamba kwambiri a zida zowunikira ma chromatographic.
