Polycarbonate (PC) ndi imodzi mwazinthu zosunthika kwambiri za thermoplastics zomwe zimagwiritsidwa ntchito pamagalasi apagalimoto, zamagetsi zamagetsi, zovala zamaso, ndi zida zoteteza. Mphamvu yake yayikulu, kumveka bwino, komanso kukhazikika kwake kumapangitsa kuti ikhale yabwino pamapulogalamu ofunikira. Komabe, chodziwika bwino chodziwika bwino cha PC ndi kuuma kwake kocheperako, komwe kumapangitsa kuti pakhale kukanda bwino komanso kukana kuvala, makamaka pokhudzana pafupipafupi kapena kupwetekedwa.
Ndiye, opanga angalimbikitse bwanji kulimba kwapa PC popanda kusokoneza kuwonekera kwake kapena makina ake? Tiyeni tifufuze njira zothetsera mavuto osiyanasiyana komanso njira zovomerezeka zamakampani kuti tithane ndi zovutazi.
Yankho: Phatikizani zowongoleredwa pakukonza ndikusintha kwapamtunda ndi matekinoloje apamwamba achitetezo.
1. Zowonjezera Zopangira Silicone: Mafuta amkati
Kuphatikizira zowonjezera za silicone zogwira ntchito kwambiri, monga polydimethylsiloxane (PDMS) kapena ma masterbatches opangidwa ndi siloxane monga Dow MB50-001, Wacker GENIOPLAST, ndi SILIKE Silicone Masterbatch LYSI-413, mu mapangidwe a polycarbonate (PC) amatha kupititsa patsogolo magwiridwe antchito azinthu. Pogwiritsa ntchito zowonjezera izi pamlingo wotsitsa wa 1-3%, mutha kuchepetsa mikangano, yomwe imathandizira kukana kukana komanso kulimba kwa kuvala.
Ubwino Wachikulu: Zowonjezera za silicone izi, monga zowonjezera ndi zosintha za PC, sizimangosunga kumveka bwino kwa PC komanso zimawonjezera kuyanika pamwamba. Izi zimapangitsa kuti kuwonongeka kwa malo kuchepe kwambiri mukakumana ndi abrasive, zomwe zimapangitsa kuti zinthu zizikhala ndi moyo wautali.
Langizo Lothandiza: Kuti muwonetsetse kuti mukugwira ntchito bwino, ndikofunikira kuti mukwaniritse kubalalitsidwa koyenera kudzera pawiri-screw extrusion, yomwe imathandiza kupewa kupatukana kwa gawo ndikukulitsa phindu lazowonjezera.
Chengdu SILIKE Technology Co., Ltd ndiwogulitsa kwambiri ku Chinazowonjezera za silicone zamapulasitiki osinthidwa. Kampaniyo imapereka mayankho aukadaulo opangidwa kuti apititse patsogolo magwiridwe antchito ndi magwiridwe antchito azinthu zosiyanasiyana zapulasitiki. Chimodzi mwazinthu zake zodziwika bwino ndiSILIKE Silicone Masterbatch LYSI-413,kupangidwa kothandiza kwambiri kwa ma pelletized komwe kumakhala ndi 25% yolemera kwambiri ya siloxane polima yomwazikana mu polycarbonate (PC). Chowonjezera ichi chochokera ku silikoni ndichothandiza kwambiri pamakina ogwirizana ndi PC. Imawongolera magwiridwe antchito ndi mawonekedwe apamwamba popititsa patsogolo kuyenda kwa utomoni, kuthandizira kudzaza nkhungu ndi kutulutsa, kuchepetsa torque ya extruder, kutsitsa kokwanira kwa mikangano, ndikupereka kukana kwamphamvu kwa mar ndi abrasion. Kuphatikiza apo, masterbatch yochokera ku siloxane iyi imagwira ntchito ngati chowonjezera chotsutsana ndi zikande, kupangitsa kuti ikhale yankho labwino kwambiri pakuwonjezera kukana kwazinthu za PC ndikuwongolera magwiridwe antchito awo onse ndi kulimba.
2. Zovala Zolimba Zochiritsira za UV ndi Nanotechnology
Ikani zokutira zolimba za siloxane kapena zosakanizidwa organic-inorganic (monga Momentive SilFORT AS4700 kapena PPG's DuraShield). Zovala izi zimakwaniritsa kulimba kwa pensulo mpaka 7H-9H, kumathandizira kwambiri kukana kukankha.
Phatikizani zokutira zochiritsika ndi UV zokhala ndi nanoparticles (monga silika kapena zirconia) kuti mupititse patsogolo kukana ma abrasion.
Phindu: Amapereka chotchinga choteteza ku zokanda, makemikolo, ndi kuwonongeka kwa UV, chomwe chili choyenera kugwiritsa ntchito magalasi ndi magalimoto.
Ntchito: Gwiritsani ntchito zokutira zoviika, zopopera, kapena zoyakira kuti mukhwime mofanana (5-10 µm).
3. Nanocomposite Reinforcement
Onjezani ma nanofillers ngati nanosilica, alumina, kapena graphene oxide (0.5-2% polemera) ku matrix a PC. Izi zimawonjezera kuuma kwa pamwamba ndikuwongolera kukana kovala popanda kukhudza kwambiri kuwonekera ngati kukula kwa tinthu ndi <40 nm.
Chitsanzo: Kafukufuku akuwonetsa kuti 1% nanosilica mu PC imatha kusintha kukana kwa Taber abrasion ndi 20-30%.
Langizo: Gwiritsani ntchito zofananira (mwachitsanzo, zolumikizira za silane) kuwonetsetsa kubalalitsidwa kofanana ndikupewa kusakanikirana.
4. Kusakaniza kwa PC kwa Magwiridwe Oyenera
Phatikizani PC ndi PMMA (10-20%) kuti muwonjezere kulimba kwapamwamba kapena ndi PBT kuti mukhale wolimba mtima komanso kuti musavale. Izi zimaphatikizira kukana kolimba kolimba ndi mphamvu yachilengedwe ya PC.
Chitsanzo: Kuphatikizika kwa PC/PMMA ndi 15% PMMA kumatha kukulitsa kuuma kwapamtunda kwinaku kumveketsa bwino zowonetsera.
Chenjezo: Konzani zophatikizana kuti mupewe kusokoneza kukhazikika kwamafuta kapena kulimba kwa PC.
5. Njira Zapamwamba Zosinthira Pamwamba
Kuchiza kwa Plasma: Ikani plasma-enhanced chemical vapor deposition (PECVD) kuti muyike zokutira zoonda, zolimba ngati silicon oxynitride (SiOxNy) pa PC. Izi zimathandizira kukana zikande komanso kuvala katundu.
Laser Texturing: Pangani mawonekedwe ang'onoang'ono kapena a nano-scale pa PC kuti muchepetse malo olumikizirana ndi kufalitsa zingwe, ndikuwongolera kukhazikika kokongola.
Phindu: Kulemberana mameseji kumatha kuchepetsa mikanda yowoneka ndi 40% pamakompyuta olumikizana kwambiri.
6. Zowonjezera Zophatikiza za Synergy
Phatikizani zowonjezera za silikoni ndi zowonjezera zina zogwira ntchito monga PTFE (polytetrafluoroethylene) ma micropowder (0.5-1%) pazotsatira za synergistic. PTFE imawonjezera mafuta, pomwe silikoni imathandizira kukana kuvala.
Chitsanzo: Kuphatikizika kwa 2% silikoni masterbatch ndi 0.5% PTFE kumatha kuchepetsa mavalidwe ndi 25% pamapulogalamu otsetsereka.
7. Kachitidwe Kokongoletsedwa:
Gwiritsani ntchito kumeta ubweya wambiri kuti mubale zowonjezera zowonjezera ndi zodzaza mofanana. Sungani kutentha kwa PC pokonza (260-310 ° C) kuti mupewe kuwonongeka.
Gwiritsirani ntchito njira zomangira molondola (monga jekeseni ndi nkhungu zopukutidwa) kuti muchepetse kuwonongeka komwe kungayambitse mikanda.
Magawo opangidwa ndi Anneal pa 120-130 ° C kuti athetse kupsinjika kwamkati, kukonza magwiridwe antchito anthawi yayitali.
Innovation Watch: Kudzichiritsa ndi Zovala za DLC Zikukwera
Ukadaulo womwe ukubwera monga zokutira zodzichiritsa zokha (zotengera chemistry ya polyurethane kapena siloxane) ndi zokutira zokhala ngati diamondi (DLC) zimapereka mayankho otsimikizira zamtsogolo pamapulogalamu a PC okhazikika, okhudza kwambiri. Ngakhale kuti akadali otsika mtengo pazinthu zogulitsidwa kwambiri, matekinolojewa akuwonetsa lonjezano pamagetsi apamwamba, magalimoto, ndi ndege.
Njira Yolangizidwa Yogwira Ntchito Moyenera mu Engineering Thermoplastics
Kwa opanga omwe akufuna njira yothandiza, yowongoka kuti apititse patsogolo kulimba kwa PC, timalimbikitsa:
1)2% UHMW Silicone Yowonjezera yamafuta amkati
2) Siloxane-based UV Coating + 1% Nano Silika chifukwa cha kuuma kwa pamwamba
3) Micro-Texturing kudzera pa Laser Molding kuti abise zokopa
Njira yazinthu zitatuzi imapereka ndalama zogwirira ntchito, kugwirizanitsa ntchito, ndi ntchito, zomwe zimapangitsa kuti zikhale zoyenera kwa zinthu zomwe zimavala tsiku ndi tsiku komanso zimafuna kukongola kwanthawi yaitali.
Zatsimikiziridwa Zamakampani
Malinga ndi lipoti la 2024 lolembedwa ndi MarketsandMarkets, msika wapadziko lonse lapansi wokutira wokutira ukuyembekezeka kupitilira $ 1.3 biliyoni pofika 2027, motsogozedwa ndi kufunikira kwa mapulasitiki osayamba kukwapula pazowonetsa zamagalimoto, zida zam'manja, ndi magalasi owoneka bwino. Opanga zinthu ndi ophatikizira kuphatikiza zowonjezera zowonjezera ndi nano-fillers ali okonzeka kutsogolera m'badwo wotsatira wazinthu zokhazikika za PC.
Mwakonzeka kulimbikitsa mapulasitiki anu aumisiri ngati PC yokhala ndi zokanda bwino komanso kukana kuvala?
Onani SILIKEzowonjezera mapulasitikimayankho omwe amakulitsa ma processing ndi zinthu zakumtunda kuti akwaniritse zomwe mukufuna.
