I-Polycarbonate (PC) ingenye yama-thermoplastic obunjiniyela aguquguqukayo kakhulu asetshenziswa kumalensi ezimoto, kuma-electronics asetshenziswa njalo, ezigqokweni zamehlo, nasezintweni zokuzivikela. Amandla ayo anamandla aphezulu, ukucaca kokukhanya, kanye nokuqina kobukhulu kwenza kube kuhle kakhulu ekusetshenzisweni okunzima. Kodwa-ke, inkinga eyaziwayo ye-PC ubulukhuni bayo obuphansi bomphezulu, okuholela ekuklwebhekeni okubi kanye nokumelana nokuguguleka—ikakhulukazi ngaphansi kwezimo zokuthintana njalo noma zokukhuhlana.
Ngakho-ke, abakhiqizi bangakuthuthukisa kanjani ukuqina kobuso be-PC ngaphandle kokubeka engcupheni ukucaca kwayo noma izakhiwo zayo zemishini? Ake sihlole izixazululo ezahlukahlukene ezisebenzayo kanye namasu aqinisekiswe yimboni ukuze sinqobe lezi zinselele.
Isixazululo: Hlanganisa ukuthuthukiswa kokucubungula kanye nokuguqulwa kwezakhiwo ezingaphezulu nobuchwepheshe bokuvikela obuthuthukisiwe.
1. Izithasiselo Ezisekelwe ku-Silicone: Ukuthambisa Kwangaphakathi
Ukufaka izithasiselo ze-silicone ezisebenza kahle kakhulu, njenge-polydimethylsiloxane (PDMS) noma i-masterbatches esekelwe ku-siloxane njenge-Dow MB50-001, i-Wacker GENIOPLAST, kanye ne-SILIKE Silicone Masterbatch LYSI-413, ekwakhiweni kwe-polycarbonate (PC) kungathuthukisa kakhulu ukusebenza kwezinto. Ngokusebenzisa lezi zithasiselo ezingeni lokulayisha elingu-1-3%, unganciphisa ngempumelelo i-coefficient of friction, okuthuthukisa kokubili ukumelana nokuklwebheka kanye nokuqina kokuguguleka.
Izinzuzo Eziyinhloko: Lezi zithasiselo ze-silicone, njengezithasiselo zokucubungula i-PC kanye neziguquli, azigcini nje ngokulondoloza ukucaca kokukhanya kwe-PC kodwa futhi zikhulisa ukuthamba kwendawo. Lokhu kuholela ekunciphiseni okuphawulekayo komonakalo wendawo ngesikhathi sokuxhumana okunolaka, okuholela ekuthuthukisweni kwesikhathi eside somkhiqizo.
Icebiso Eliwusizo: Ukuqinisekisa ukusebenza kahle, kubalulekile ukufeza ukusabalala okufanele ngokusebenzisa i-extrusion enama-screw amabili, okusiza ukuvimbela ukuhlukaniswa kwesigaba futhi kwandisa izinzuzo zezithasiselo.
I-Chengdu SILIKE Technology Co., Ltd ingumhlinzeki ohamba phambili waseShayina we-izithasiselo ze-silicone zepulasitiki eziguquliweLe nkampani inikeza izixazululo ezintsha ezenzelwe ukuthuthukisa ukusebenza kanye nokusebenza kwezinto ezahlukahlukene zepulasitiki. Omunye wemikhiqizo yabo evelele yi-I-SILIKE Silicone Masterbatch LYSI-413,ifomula ephumelela kakhulu eyenziwe nge-pellet equkethe i-polymer ye-siloxane enesisindo sama-molecule esingu-25% esakazeke kwi-polycarbonate (PC). Lesi sithako esisekelwe ku-silicone sisebenza kahle kakhulu ezinhlelweni ze-resin ezihambisana ne-PC. Sithuthukisa izakhiwo zokucubungula kanye nekhwalithi yobuso ngokuthuthukisa ukugeleza kwe-resin, sisiza ekugcwaliseni nasekukhululekeni kwesikhunta, sinciphise i-torque ye-extruder, sehlise i-coefficient of friction, futhi sinikeze ukumelana okuphezulu kwe-mar kanye ne-abrasion. Ngaphezu kwalokho, le masterbatch esekelwe ku-siloxane isebenza njengesithako esilwa nokuklwebheka, okwenza kube yisisombululo esihle kakhulu sokwandisa ukumelana nokuklwebheka kwemikhiqizo ye-PC futhi ekugcineni sithuthukise ukusebenza kwayo kanye nokuqina kwayo.
2. Izimbozo Eziqinile Ezingalapheki Nge-UV Nge-Nanotechnology
Faka izembozo eziqinile ezisekelwe ku-siloxane noma ezihlanganisiwe ze-organic-inorganic (isb., i-Momentive SilFORT AS4700 noma i-PPG's DuraShield). Lezi zembozo zithola ubulukhuni bepensela obufika ku-7H-9H, okuthuthukisa kakhulu ukumelana nokuklwebheka.
Faka izembozo ezilapheka nge-UV ezinama-nanoparticles (isb., i-silica noma i-zirconia) ukuze uthuthukise ukumelana nokuguguleka.
Inzuzo: Ihlinzeka ngesithiyo esivikelayo ekuklwebhekeni, amakhemikhali, kanye nokuwohloka kwe-UV, ilungele ukusetshenziswa kokukhanya kanye nezimoto.
Ukusetshenziswa: Sebenzisa i-dip-coating, i-spray-coating, noma i-flow-coating ukuze kube nobukhulu obufanayo (5-10 µm).
3. Ukuqinisa i-Nanocomposite
Faka ama-nanofiller afana ne-nanosilica, i-alumina, noma i-graphene oxide (0.5-2% ngesisindo) ku-matrix ye-PC. Lokhu kwandisa ubulukhuni bomphezulu futhi kuthuthukise ukumelana nokuguguleka ngaphandle kokuthinta kakhulu ukucaca uma usayizi wezinhlayiya ungaphansi kuka-40 nm.
Isibonelo: Izifundo zibonisa ukuthi i-nanosilica engu-1% ku-PC ingathuthukisa ukumelana nokuklwebheka kwe-Taber ngo-20-30%.
Icebiso: Sebenzisa izinto ezihambisanayo (isb., izinto zokuhlanganisa i-silane) ukuqinisekisa ukuhlakazeka okufanayo nokugwema ukuhlangana.
4. Ama-PC Blends Okusebenza Okulinganiselayo
Hlanganisa i-PC ne-PMMA (10-20%) ukuze uthuthukise ubulukhuni bomphezulu noma nge-PBT ukuze kube nokuqina okuthuthukisiwe kanye nokumelana nokuguguleka. Lokhu kuhlanganisa ukulinganisela ukumelana nokuklwebheka namandla okushaya e-PC.
Isibonelo: Ingxube ye-PC/PMMA ene-15% PMMA ingandisa ubulukhuni bendawo ngenkathi igcina ukucaca kwezinhlelo zokusebenza zokubonisa.
Isexwayiso: Lungiselela izilinganiso zokuxuba ukuze ugweme ukulimaza ukuzinza noma ukuqina kokushisa kwe-PC.
5. Amasu Okuguqula Okuphezulu Okuthuthukisiwe
Ukwelashwa nge-Plasma: Faka i-plasma-enhanced chemical vapor deposition (PECVD) ukuze ufake izinto eziqinile nezincane njenge-silicon oxynitride (SiOxNy) ezindaweni ze-PC. Lokhu kuthuthukisa ukumelana nokuklwebheka kanye nezakhiwo zokuguguleka.
Ukuthunga nge-Laser: Dala ukuthungwa okuncane noma okuncane ebusweni be-PC ukuze unciphise indawo yokuxhumana futhi usakaze imihuzuko, uthuthukise ukuqina kobuhle.
Inzuzo: Ukuthunga kunganciphisa imihuzuko ebonakalayo ngamaphesenti afinyelela ku-40 ezinsizeni ezithinta kakhulu.
6. Izinhlanganisela ezengeziwe ze-Synergy
Hlanganisa izithasiselo ze-silicone nezinye izithasiselo ezisebenzayo njenge-PTFE (polytetrafluoroethylene) micropowders (0.5-1%) ukuze uthole imiphumela yokusebenzisana. I-PTFE ithuthukisa ukuthambisa, kuyilapho i-silicone ithuthukisa ukumelana nokuguguleka.
Isibonelo: Ingxube ye-2% silicone masterbatch kanye ne-0.5% PTFE inganciphisa amazinga okuguguleka ngo-25% ekusetshenzisweni kokushelela.
7. Izimo Zokucubungula Ezilungiselelwe:
Sebenzisa i-compound eshefa kakhulu ukuze usakaze izithasiselo kanye nama-filler ngokulinganayo. Gcina amazinga okushisa okucubungula ama-PC (260-310°C) ukuze ugweme ukubola.
Sebenzisa amasu okubumba ngokunemba (isb., ukubumba ngomjovo ngezikhunta ezipholishiwe) ukuze unciphise amaphutha ebusweni angabangela imihuzuko.
Izingxenye ezibunjiwe ze-Anneal ku-120-130°C ukuze kuncishiswe ukucindezeleka kwangaphakathi, kuthuthukiswe ukusebenza kokuguguleka kwesikhathi eside.
Iwashi Lokusungula Izinto Ezintsha: Ukuziphilisa Nokumboza Nge-DLC Kuyanda
Ubuchwepheshe obusha njengezembozo zokuziphilisa (ezisekelwe kumakhemikhali e-polyurethane noma e-siloxane) kanye nezembozo ezifana ne-carbon (DLC) zinikeza izixazululo ezivikela ikusasa lezinhlelo zokusebenza ze-PC eziqinile kakhulu nezithinta kakhulu. Nakuba zisesezindleko eziphansi emikhiqizweni ethengiswa kakhulu, lobu buchwepheshe bubonisa ithemba kuma-elekthronikhi asezingeni eliphezulu, ezimotweni, kanye nasezindiza.
Indlela Enconywayo Yokusebenza Okuhle Kakhulu Kuma-Thermoplastic Obunjiniyela
Kubakhiqizi abafuna ikhambi elisebenzayo nelikwazi ukwandiswa ukuze kuthuthukiswe ukuqina kobuso be-PC, sincoma:
1)Isengezo se-Silicone esingu-2% se-UHMW sokugcoba kwangaphakathi
2) I-UV Coating esekelwe ku-Siloxane + 1% Nano Silica yokuqina kobuso
3) I-Micro-Texturing nge-Laser Molding ukufihla imihuzuko
Le ndlela enezinhlangothi ezintathu iletha ibhalansi yokusebenzisa kahle izindleko, ukuhambisana kokucubungula, kanye nokusebenza, okwenza kube kuhle kakhulu emikhiqizweni evezwe ekugugeni kwansuku zonke futhi edinga ubuhle obuhlala isikhathi eside.
