Ntchito yolemera Yotambasulidwa kale chingwe cha uhmwpe cholukidwa ndi chingwe cha uhmwpe poyimitsa sitima

Kodi UHMWPE imayimira chiyani?

UHMWPE imayimira ultra high molecular weight polyethylene.Mutha kuyimvanso ikutchedwa HMPE, kapena ndi mayina amtundu monga Spectra, Dyneema kapena Stealth Fibre.UHMWPE imagwiritsidwa ntchito m'mizere yogwira ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza nsomba zam'madzi, zamalonda, kukwera mapiri, ndi ulimi wam'madzi.Ili ndi mikhalidwe yambiri yomwe imapangitsa kuti ikhale yabwino kusankha malo onyowa;ndizopepuka kuti ziyandama, zimakhala za hydrophobic (zimathamangitsa madzi) ndipo zimakhala zolimba pakatentha kwambiri.Mupezanso kuti imagwiritsidwa ntchito poyendetsa ma yachting, makamaka ndi matanga ndi kukwera, chifukwa kutsika kwake kumapangitsa kuti ma sail azikhala ndi mawonekedwe abwino pomwe akulimbana kwambiri ndi abrasion. ndiye chingwe chosankha chamizere yothandizira zombo, zida zakunyanja ndi akasinja.Ndiwotchuka kwambiri poyendetsa zombo pakagwa mavuto.

Kodi maukadaulo a UHMWPE ndi ati?

UHMWPE ndi ulusi wa polyolefin, wopangidwa ndi unyolo wautali kwambiri wa polyethylene, wolumikizidwa mbali imodzi, zomwe zimapangitsa kukhala imodzi mwazingwe zolimba kwambiri zomwe zilipo.
Chifukwa cha kapangidwe kake ka maselo, UHMWPE imalimbana ndi mankhwala ambiri, kuphatikiza zotsukira, ma mineral acid ndi mafuta.Ikhoza, komabe, kuipitsidwa ndi ma oxidizing agents amphamvu.Zingwe za HMPE zimakhala ndi makulidwe a 0.97 g cm-3 okha ndipo zimakhala ndi coefficient of friction yomwe imakhala yochepa kuposa nayiloni ndi acetal.Coefficient yake ndi yofanana ndi ya polytetrafluoroethylene (Teflon kapena PTFE), koma ili ndi kukana bwino kwa abrasion.

Ulusi womwe umapanga Ultra High Molecular Weight Polyethylene umakhala ndi malo osungunuka apakati pa 144°C ndi 152°C, womwe ndi wotsikirapo kuposa ulusi wina wambiri wa polima, koma ulibe brittle point ukayesedwa pa kutentha kotsika kwambiri (-150°C. ).Zingwe zambiri sizingathe kupirira kutentha kwa -50 ° C.Chifukwa chake chingwe cha UHMWPE chimalimbikitsidwa kuti chigwiritsidwe ntchito pakati pa -150 ndi +70 °C, chifukwa sichingataye chilichonse mwazinthu zolemera kwambiri zama cell pamtunduwu.
UHMWPE kwenikweni imatchedwa pulasitiki yaukadaulo yapadera, yogwiritsidwa ntchito pazinthu zina zambiri kuposa kupanga zingwe.M'malo mwake, UHMWPE yachipatala yakhala ikugwiritsidwa ntchito m'maimplants olowa kwa zaka zambiri, makamaka m'malo a mawondo ndi chiuno.Izi ndichifukwa chakugundana kwake kochepa, kulimba, kulimba kwamphamvu, kukana mankhwala owononga komanso kuyanjana kwabwino kwambiri.

Mungadabwe kudziwa kuti pulasitiki ya UHMW ndi chisankho chodziwika bwino cha zida zankhondo ndi asitikali ndi apolisi, kachiwiri chifukwa cha kukana kwake komanso kulemera kwake.

Kuphatikiza pa mphamvu zake zochititsa chidwi, UHMWPE ndi yopanda pake, yopanda poizoni komanso yopanda fungo, chifukwa chake pulasitikiyi imatha kugwiritsidwa ntchito popanga zakudya komanso kupanga.Ndizotetezeka kwa onse ogwiritsa ntchito mapeto ndi ogwira ntchito opanga.

Kodi UHMWPE ndi chiyani?

Kupambana kwa UHMWPE ndi monga:  Malo osungunuka kwambiri (kupitirira 144 ° C)  Kutsika kochepa - kumayandama pamadzi a m'nyanja  Kutsika kwambiri  Kutetezeka kuposa waya - kumathyoka motsatira mzere  Kuchita kwakukulu  Kuchepa kwa chinyezi (kuthamangitsa madzi)  Kusamva mankhwala (kupatula ma oxidising acid) Kulimba kwambiri - kulimba kuposa chitsulo cholimba UV kukana - kutalikitsa moyo wa chingwe chako Kudzipaka mafuta - kutsika kokwanira kwa friction  Superior abrasion resistance  Kutambasula kwambiri (3–4% pakuduka) katundu)  Kuchepetsa mtengo poyerekeza ndi zingwe zachitsulo Low dielectric constant - pafupifupi transparent to radar Vibration damping  Kukonza kochepa  Kutsika kwa magetsi  Kutopa kwabwino kwambiri Zingwe zogwira ntchito kwambiri zikugwiritsidwa ntchito mochulukira kusintha zitsulo ndi ulusi wamba.Ndiwolimba kwambiri kuposa chitsulo koma 1/8 yokha ya kulemera kwa mawaya achitsulo ofanana.Mwa kuyankhula kwina, ndi mphamvu zosachepera 8 kuposa zingwe zachitsulo.Mizere yochuluka kwambiri ya polyethylene (UHMWPE) imakhala yocheperapo, yopepuka komanso yodzipaka yokha, motero ndiyothandiza kwambiri kugwirika kuposa zingwe wamba zachitsulo.Kuphatikiza pa mphamvu zawo, amakhalanso otetezeka kwambiri, opanda mphamvu zochepa kuposa chingwe chachitsulo.Chingwe chachitsulo chikaduka, waya wachitsulowo amamasuka mofulumira, n’kusiya nsonga zakuthwa za lumo zikuyenda mosayembekezereka.Chingwe cha UHMWPE chikaduka, kuyambiranso kumakhala kochepa.Chifukwa cha kupanga kwake kwa maunyolo aatali a polyethene olumikizidwa mbali imodzi, ngati athyoka (zomwe sizingatheke chifukwa cha mphamvu zake zomangira), chingwecho chidzawonetsa mzere wokhazikika, wodziwikiratu.UHMWPE wodzipangira okha ulusi umakhala ndi chogwirira cha waxy ndi pamwamba, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira, ngakhale izi zikutanthauza kuti sizigwira mfundo bwino.Komabe, ngakhale kuti ndi yosalala, imakhala yosasunthika kuwirikiza ka 15 kuposa chitsulo cha carbon.Pomaliza, poyerekezera ndi zingwe zachitsulo kapena zingwe za poliyesitala, zingwe za UHMWPE ndi zazing'ono mu voliyumu chifukwa cha zochepa zomwe zimafunikira kuti tipeze zotsatira zomwezo.Izi zimapangitsa kuti zikhale zosavuta kusunga.
