I-Polycarbonate (PC) ingenye ye-thermoplastic yobunjiniyela eguquguquka kakhulu esetshenziswa kumalensi ezimoto, izinto zikagesi zabathengi, izingubo zamehlo, negiya lokuvikela. Amandla ayo omthelela ophezulu, ukucaca kokubonakalayo, nokuzinza kohlangothi kuyenza ilungele izinhlelo zokusebenza ezifunayo. Kodwa-ke, i-drawback eyaziwa kakhulu ye-PC ubulukhuni bayo obuphansi obuphezulu, okuholela ekuklweleni okumpofu nokumelana nokugqoka-ikakhulukazi ngaphansi kokuxhumana njalo noma izimo zokuhuzuka.
Ngakho-ke, abakhiqizi bangakuthuthukisa kanjani ukuqina kwe-PC ngaphandle kokubeka engcupheni ukubonakala kwayo noma izakhiwo zemishini? Ake sihlole uhla lwezixazululo ezisebenzayo kanye namasu aqinisekisiwe embonini ukuze sinqobe lezi zinselele.
Isixazululo: Hlanganisa izithuthukisi zokucubungula kanye nokulungiswa kwendawo engaphezulu nobuchwepheshe bokuvikela obuthuthukile.
1. Izithasiselo Ezisekelwe ku-Silicone: Ukuthambisa kwangaphakathi
Ukufaka izithasiselo ze-silicone ezisebenza kahle kakhulu, njenge-polydimethylsiloxane (PDMS) noma ama-masterbatches asekelwe ku-siloxane afana ne-Dow MB50-001, i-Wacker GENIOPLAST, ne-SILIKE Silicone Masterbatch LYSI-413, ekwakhiweni kwe-polycarbonate (PC) kungathuthukisa kakhulu ukusebenza kwezinto ezibonakalayo. Ngokusebenzisa lezi zengezo ezingeni lokulayisha lika-1-3%, unganciphisa ngempumelelo i-coefficient of friction, okuthuthukisa kokubili ukumelana nokuklwebheka nokuqina kokugqoka.
Izinzuzo Eziyinhloko: Lezi zithako ze-silicone, njengezithasiselo ezicutshungulwa yi-PC, azigcini nje ngokugcina ukucaca kwe-PC kodwa futhi zithuthukisa ukuthambisa kwendawo. Lokhu kuholela ekuncipheni okuphawulekayo kokulimala kwendawo ngesikhathi sokuxhumana okulimazayo, ekugcineni kuholele ekuthuthukisweni kokuphila isikhathi eside komkhiqizo.
Ithiphu Elisebenzayo: Ukuqinisekisa ukusebenza okuhle, kubalulekile ukuzuza ukuhlakazeka okufanele ngokusebenzisa i-twin-screw extrusion, esiza ukuvimbela ukuhlukaniswa kwesigaba futhi kwandise izinzuzo zezithasiselo.
I-Chengdu SILIKE Technology Co., Ltd ingumphakeli ohamba phambili waseShayina weizithasiselo ze-silicone zamapulasitiki aguquliwe. Inkampani inikeza izixazululo ezintsha eziklanyelwe ukuthuthukisa ukusebenza nokusebenza kwezinto ezihlukahlukene zepulasitiki. Omunye wemikhiqizo yabo evelele yi-SILIKE Silicone Masterbatch LYSI-413,ukwakheka kwe-pelletized okuphumelelayo kakhulu okuqukethe u-25% we-ultra-high molecular weight siloxane polymer ehlakazekile ku-polycarbonate (PC). Lesi sengezo esisekelwe ku-silicone sisebenza kakhulu ezinhlelweni ze-PC-compatible resin. Ithuthukisa izakhiwo zokucubungula kanye nekhwalithi ephezulu ngokuthuthukisa ukugeleza kwe-resin, kusiza ukugcwaliswa kwesikhunta kanye nokukhululwa, ukunciphisa i-extruder torque, ukwehlisa i-coefficient of friction, futhi inikeze ukumelana okuphezulu kwe-mar nokuhuzuka. Ukwengeza, le masterbatch esekwe ku-siloxane isebenza njengesengezo sokulwa nokuklwebheka, okuyenza ibe yisixazululo esihle kakhulu sokwandisa ukumelana nokuklwebheka kwemikhiqizo ye-PC futhi ekugcineni ithuthukise ukusebenza kwayo konke nokuqina.
2. I-UV-Curable Hard Coatings nge-Nanotechnology
Faka ama-siloxane athuthukisiwe asuselwa ku-siloxane noma ama-organic-inorganic hard coatings (isb., i-Momentive SilFORT AS4700 noma i-PPG's DuraShield). Lezi zembatho zifinyelela ubulukhuni bepensela kuze kufike ku-7H-9H, kuthuthukisa kakhulu ukumelana nokuklwebheka.
Faka okunamathelayo okulapheka kwe-UV nama-nanoparticles (isb, i-silica noma i-zirconia) ukuze uthuthukise ukumelana nokuhuzuka.
Inzuzo: Inikeza umgoqo ovikelayo ngokumelene nokuklwebheka, amakhemikhali, nokuwohloka kwe-UV, elungele ukusetshenziswa kokubona nezimoto.
Isicelo: Sebenzisa i-dip-coating, spray-coating, noma flow-coating ukuze uthole ukujiya okufanayo (5-10 µm).
3. I-Nanocomposite Reinforcement
Engeza ama-nanofiller afana ne-nanosilica, i-alumina, noma i-graphene oxide (0.5-2% ngesisindo) ku-PC matrix. Lokhu kukhulisa ubulukhuni bobuso futhi kuthuthukise ukumelana nokugqokwa ngaphandle kokuthikameze kakhulu ukubonakala uma usayizi wezinhlayiyana ungu-<40 nm.
Isibonelo: Ucwaningo lubonisa i-1% ye-nanosilica ku-PC ingathuthukisa ukumelana ne-Taber abrasion ngo-20-30%.
Ithiphu: Sebenzisa izinto ezihambisanayo (isb., ama-silane coupling agents) ukuze uqinisekise ukuhlakazeka okufanayo futhi ugweme ukuhlangana.
4. Izingxube Ze-PC Zokusebenza Okunokulinganisela
Hlanganisa i-PC ne-PMMA (10-20%) ukuze uthuthukise ubulukhuni bobuso noma nge-PBT ukuze uthole ukuqina okuthuthukisiwe nokumelana nokugqokwa. Lokhu kuhlanganisa ukumelana nokuklwebheka kwebhalansi namandla omthelela wemvelo we-PC.
Isibonelo: Inhlanganisela ye-PC/PMMA no-15% PMMA ingakhuphula ubulukhuni bendawo kuyilapho igcina ukucaca kwezinhlelo zokusebenza zokubonisa.
Isexwayiso: Lungiselela izilinganiso zokuhlanganisa ukuze ugweme ukubeka engozini ukuzinza noma ukuqina kwe-PC.
5. Izindlela Ezithuthukisiwe Zokuguqula Umphezulu
Ukwelashwa Kwe-Plasma: Faka i-plasma-enhanced chemical vapor deposition (PECVD) ukufaka okucolile okuqinile njenge-silicon oxynitride (SiOxNy) endaweni ye-PC. Lokhu kuthuthukisa ukumelana nokuklwebheka kanye nezakhiwo zokugqoka.
I-Laser Texturing: Dala ukwakheka kwe-micro- noma nano-scale endaweni ye-PC ukuze unciphise indawo yokuxhumana futhi usabalalise imihuzuko, uthuthukise ukuqina kobuhle.
Inzuzo: Ukuthumela umbhalo kunganciphisa imihuzuko ebonakalayo kufika ku-40% ezinhlelweni zokuxhumana okuphezulu.
6. Izinhlanganisela Additive for Synergy
Hlanganisa izithasiselo ze-silicone nezinye izithasiselo ezisebenzayo ezifana ne-PTFE (polytetrafluoroethylene) micropowder (0.5-1%) ukuze uthole imiphumela ye-synergistic. I-PTFE ithuthukisa ukuthambisa, kuyilapho i-silicone ithuthukisa ukumelana nokugqokwa.
Isibonelo: Inhlanganisela ye-2% silicone masterbatch kanye no-0.5% PTFE ingehlisa izinga lokuguga ngo-25% ezinhlelweni zokuslayida.
7. Izimo Zokucubungula Ezithuthukisiwe:
Sebenzisa inhlanganisela ye-high-shear ukuze uhlakaze ngokulinganayo izithasiselo nezigcwalisi. Gcina izinga lokushisa lokucubungula i-PC (260-310°C) ukuze ugweme ukucekelwa phansi.
Sebenzisa amasu okubumba anembayo (isb, ukubumba umjovo ngesikhunta esiphucuziwe) ukuze unciphise ukonakala kwendawo okungase kuqalise imihuzuko.
Izingxenye ezibunjiwe ze-Anneal ku-120-130°C ukuze zikhulule izingcindezi zangaphakathi, zithuthukise ukusebenza kokugqoka kwesikhathi eside.
I-Innovation Watch: Ukuziphilisa kanye ne-DLC Coatings iyakhuphuka
Ubuchwepheshe obusafufusa obufana nezingubo zokuziphilisa (okusekelwe kukhemikhali ye-polyurethane noma ye-siloxane) nezindwangu zekhabhoni efana nedayimane (i-DLC) zinikeza izixazululo zobufakazi besikhathi esizayo zezinhlelo zokusebenza ze-PC ezihlala isikhathi eside, ezithinta kakhulu. Nakuba zisabiza kakhulu emikhiqizweni emakethe enkulu, lobu buchwepheshe bubonisa isithembiso kuma-electronics aphambili, ezezimoto, kanye ne-aerospace.
Indlela Enconyiwe Yokusebenza Okulungile Kobunjiniyela Thermoplastics
Kubakhiqizi abafuna isixazululo esisebenzayo, esinokwehla sokuthuthukisa ukuqina kwendawo ye-PC, sincoma:
1)2% UHMW Silicone Additive for lubricity yangaphakathi
