Polycarbonate (PC) ndi imodzi mwa ma thermoplastics opangidwa ndi uinjiniya omwe amagwiritsidwa ntchito kwambiri mu magalasi a magalimoto, zamagetsi, zovala zodzitetezera. Mphamvu yake yogwira ntchito, kuwala kwake, komanso kukhazikika kwake zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito molimbika. Komabe, vuto lodziwika bwino la PC ndi kuuma kwake pang'ono pamwamba, komwe kumapangitsa kuti isakandane bwino komanso isawonongeke—makamaka ikakhudzidwa pafupipafupi kapena ikakhudzidwa kwambiri.
Ndiye, kodi opanga angawonjezere bwanji kulimba kwa pamwamba pa PC popanda kusokoneza kuwonekera bwino kapena mawonekedwe ake amakina? Tiyeni tifufuze njira zosiyanasiyana zogwira mtima komanso njira zovomerezeka ndi makampani kuti tithetse mavutowa.
Yankho: Phatikizani zowonjezera pa kukonza ndi kusintha kwa malo pamwamba ndi ukadaulo wapamwamba woteteza.
1. Zowonjezera Zochokera ku Silicone: Kupaka mafuta mkati
Kuphatikiza zowonjezera za silicone zogwira ntchito bwino, monga polydimethylsiloxane (PDMS) kapena siloxane-based masterbatches monga Dow MB50-001, Wacker GENIOPLAST, ndi SILIKE Silicone Masterbatch LYSI-413, mu mapangidwe a polycarbonate (PC) kungathandize kwambiri magwiridwe antchito a zinthuzo. Pogwiritsa ntchito zowonjezerazi pamlingo wokweza wa 1-3%, mutha kuchepetsa bwino coefficient of friction, zomwe zimapangitsa kuti kukana kukanda komanso kukalamba kukhale kolimba.
Ubwino Waukulu: Zowonjezera za silikoni izi, monga zowonjezera ndi zosintha za PC, sizimangosunga kuwala kwa PC kokha komanso zimawonjezera kunyezimira kwa pamwamba. Izi zimapangitsa kuti kuwonongeka kwa pamwamba kuchepe kwambiri panthawi yokhudzana ndi abrasive, zomwe zimapangitsa kuti zinthu zikhale bwino kwa nthawi yayitali.
Malangizo Othandiza: Kuti muwonetsetse kuti zinthu zikuyenda bwino, ndikofunikira kuti pakhale kufalikira koyenera kudzera mu extrusion ya twin-screw, zomwe zimathandiza kupewa kulekanitsidwa kwa magawo ndikuwonjezera ubwino wa zowonjezera.
Chengdu SILIKE Technology Co., Ltd ndi kampani yotsogola yaku China yogulitsa zinthu zakunja.zowonjezera za silicone za pulasitiki yosinthidwaKampaniyo imapereka njira zatsopano zowonjezerera magwiridwe antchito ndi magwiridwe antchito a zipangizo zosiyanasiyana zapulasitiki. Chimodzi mwa zinthu zawo zabwino kwambiri ndiSILIKE Silicone Masterbatch LYSI-413,Fomula yothandiza kwambiri yokhala ndi ma pellets yomwe ili ndi 25% ultra-high molecular weight siloxane polymer yomwe imafalikira mu polycarbonate (PC). Chowonjezera ichi chopangidwa ndi silicone chimagwira ntchito bwino kwambiri pama resin omwe amagwirizana ndi PC. Chimawongolera mawonekedwe ogwiritsira ntchito ndi ubwino wa pamwamba mwa kukulitsa kuyenda kwa resin, kuthandizira kudzaza ndi kutulutsa nkhungu, kuchepetsa mphamvu ya extruder, kuchepetsa coefficient of friction, komanso kupereka kukana kwabwino kwa mar ndi abrasion. Kuphatikiza apo, masterbatch iyi yochokera ku siloxane imagwira ntchito ngati chowonjezera chotsutsana ndi scratch, ndikupangitsa kuti ikhale yankho labwino kwambiri pakuwonjezera kukana kwa zinthu za PC ndikuwonjezera magwiridwe antchito awo onse komanso kulimba.
2. Zophimba Zolimba Zochiritsika ndi UV ndi Nanotechnology
Ikani zomatira zolimba zopangidwa ndi siloxane kapena zosakanikirana ndi organic-inorganic (monga Momentive SilFORT AS4700 kapena PPG's DuraShield). Zomatirazi zimakhala zolimba mpaka 7H-9H, zomwe zimapangitsa kuti pensulo isakokere kwambiri.
Phatikizani zophimba zomwe zimachiritsidwa ndi UV ndi tinthu tating'onoting'ono (monga silika kapena zirconia) kuti muwonjezere kukana kwa kukanda.
Ubwino: Amapereka chotchinga choteteza ku mikwingwirima, mankhwala, ndi kuwonongeka kwa UV, ndipo ndi abwino kwambiri pakugwiritsa ntchito kuwala ndi magalimoto.
Kugwiritsa Ntchito: Gwiritsani ntchito choviika m'madzi, chopopera, kapena chopaka madzi kuti chikhale chokhuthala mofanana (5-10 µm).
3. Kulimbitsa Mphamvu ya Nanocomposite
Onjezani ma nanofillers monga nanosilica, alumina, kapena graphene oxide (0.5-2% polemera) ku PC matrix. Izi zimawonjezera kuuma kwa pamwamba ndipo zimathandizira kukana kukalamba popanda kusokoneza kwambiri kuwonekera bwino ngati kukula kwa tinthu tating'onoting'ono kuli <40 nm.
Chitsanzo: Kafukufuku akusonyeza kuti 1% nanosilica mu PC ikhoza kuwonjezera kukana kwa kukwawa kwa Taber ndi 20-30%.
Langizo: Gwiritsani ntchito zinthu zogwirizanitsa (monga zinthu zolumikizirana ndi silane) kuti muwonetsetse kuti zinthuzo zimafalikira mofanana komanso kupewa kusonkhana.
4. Zosakaniza za PC kuti zigwire bwino ntchito
Sakanizani PC ndi PMMA (10-20%) kuti muwonjezere kuuma kwa pamwamba kapena ndi PBT kuti mukhale olimba komanso osagwirizana ndi kuwonongeka. Izi zimaphatikiza kukana kukanda ndi mphamvu ya PC yogwira ntchito.
Chitsanzo: Kusakaniza kwa PC/PMMA ndi 15% PMMA kumatha kuwonjezera kuuma kwa pamwamba pomwe kumasunga kumveka bwino kwa mapulogalamu owonetsera.
Chenjezo: Sinthani ma blend ratios kuti mupewe kusokoneza kutentha kapena kulimba kwa PC.
5. Njira Zapamwamba Zosinthira Malo
Chithandizo cha Plasma: Ikani plasma-enhanced chemical vapor deposition (PECVD) kuti muike zophimba zopyapyala komanso zolimba monga silicon oxynitride (SiOxNy) pamalo a PC. Izi zimathandizira kuti khungu lisakokere kukanda komanso lisamawonongeke.
Kujambula ndi Laser: Pangani mawonekedwe ang'onoang'ono kapena ang'onoang'ono pamwamba pa PC kuti muchepetse malo olumikizirana ndi kufalitsa mikwingwirima, zomwe zimapangitsa kuti kukongola kukhale kolimba.
Ubwino: Kukongoletsa tsitsi kumatha kuchepetsa mikwingwirima yooneka ndi 40% pakugwiritsa ntchito kwambiri.
6. Kuphatikiza Zowonjezera pa Kugwirizana
Phatikizani zowonjezera za silicone ndi zowonjezera zina monga ufa wa PTFE (polytetrafluoroethylene) (0.5-1%) kuti mugwirizane. PTFE imawonjezera kukhuthala, pomwe silicone imawonjezera kukana kukalamba.
Chitsanzo: Kusakaniza kwa 2% silicone masterbatch ndi 0.5% PTFE kungathandize kuchepetsa kuwonongeka ndi 25% mu ntchito zotsetsereka.
7. Zinthu Zokonzedwa Bwino:
Gwiritsani ntchito chosakaniza chapamwamba kwambiri kuti mufalitse zowonjezera ndi zodzaza mofanana. Sungani kutentha kwa PC processing (260-310°C) kuti mupewe kuwonongeka.
Gwiritsani ntchito njira zowongolera bwino (monga, kupangira jakisoni pogwiritsa ntchito nkhungu zopukutidwa) kuti muchepetse zolakwika zomwe zingayambe kukwapula.
Ziwalo zopangidwa ndi Anneal zomwe zimapangidwa pa kutentha kwa 120-130°C kuti zichepetse kupsinjika kwamkati, ndikuwonjezera magwiridwe antchito owonongeka kwa nthawi yayitali.
Ulonda Watsopano: Kudzichiritsa Kokha ndi Zophimba za DLC Zikukula
Zipangizo zamakono zatsopano monga zophimba zodzichiritsa zokha (zochokera ku polyurethane kapena siloxane chemistry) ndi zophimba zonga diamondi (DLC) zimapereka njira zothetsera mavuto mtsogolo pakugwiritsa ntchito makompyuta olimba kwambiri komanso otakata. Ngakhale kuti ndi zotsika mtengo kwambiri pazinthu zambiri pamsika, ukadaulo uwu ukuwonetsa chiyembekezo mu zamagetsi apamwamba, magalimoto, ndi ndege.
Njira Yovomerezeka Yogwirira Ntchito Bwino Kwambiri mu Uinjiniya wa Thermoplastics
Kwa opanga omwe akufuna njira yothandiza komanso yowonjezereka yowongolera kulimba kwa pamwamba pa PC, tikupangira izi:
1)Chowonjezera cha 2% UHMW Silicone cha kudzola mkati
2) Chophimba cha UV chochokera ku Siloxane + 1% Nano Silica cholimbitsa pamwamba
3) Kujambula Zinthu Mwapang'ono Pogwiritsa Ntchito Laser Molding kuti mubise mikwingwirima
Njira imeneyi yokhala ndi mbali zitatu imapereka njira yogwiritsira ntchito bwino ndalama, kugwirizana kwa zinthu, komanso magwiridwe antchito, zomwe zimapangitsa kuti ikhale yoyenera pazinthu zomwe zimawoneka ngati zikugwiritsidwa ntchito tsiku ndi tsiku komanso zomwe zimafuna kukongola kwa nthawi yayitali.
Zatsimikiziridwa ndi Makampani
Malinga ndi lipoti la 2024 la MarketsandMarkets, msika wapadziko lonse lapansi wa zophimba zolimba ukuyembekezeka kupitirira $1.3 biliyoni pofika chaka cha 2027, chifukwa cha kufunikira kwakukulu kwa mapulasitiki osakanda m'magalimoto, zida zam'manja, ndi magalasi owonera. Ma formula ndi ma compounder ophatikiza zowonjezera zambiri ndi zodzaza zazing'ono ali pamalo abwino otsogolera m'badwo wotsatira wazinthu zolimba zopangidwa ndi makompyuta.
Kodi mwakonzeka kukulitsa mapulasitiki anu aukadaulo monga PC ndi kukana bwino kukanda ndi kuwonongeka?
Fufuzani SILIKEzowonjezera zapulasitikimayankho omwe amawonjezera kukonza ndi mawonekedwe a pamwamba kuti akwaniritse zosowa zanu zokhazikika.
