Amapulasitiki aphezulu aphezulu (optical) avame ukubhekisela ezintweni zepulasitiki ezinezakhiwo ezinhle kakhulu zeplastiki, nezinto ezijwayelekile zifaka i-polymethylmethacrylate (PMMA), i-polycarbonate (PS), ne-PS). Lezi zinto zokwenziwa zingaba nokubona okuhle, ukumelana okuhle, nokufana okubonakalayo ngemuva kokwelashwa okukhethekile.
Amapulasitiki acwebezelayo aphezulu asetshenziswa kabanzi ezinkundleni ezahlukene ze-optical, njengelensi ye-eyeglass, amalensi wekhamera, izimbotshana zezimoto, izikrini zefoni ezilandelwayo, nokunye. Ngenxa yokubonakala kwayo okuhle kakhulu kanye nezakhiwo ezibonakalayo, amapulasitiki acwebezelayo aphezulu angadlulisela ngempumelelo ukukhanya futhi ahlinzeke ngemiphumela ecacile yokubuka, ngenkathi evikela amadivayisi angaphakathi emvelweni yangaphandle. Phesheya, amapulasitiki acwebile aphezulu anezinhlobonhlobo zezicelo ekwakheni imishini ye-optical, amagobolondo omkhiqizo we-elekthronikhi, izinto zokwakha, kanye neminye imikhakha, futhi futhi ukuze ahlobane kahle nokubukeka kwe umkhiqizo.
Ezinye zezinselelo nezinkinga ezingahlangazwa ngesikhathi sokucutshungulwa kwamapulasitiki aphezulu (ama-optical) afaka okulandelayo:
Ukuguqulwa kwe-Thermal:Amapulasitiki athile acwebile aphezulu athambekele ekuguqukeni okushisayo ngesikhathi senqubo yokushisa, okuholela ekuhlanekezelweni ngosayizi womkhiqizo noma ukwakheka okuqediwe. Ngakho-ke, kuyadingeka ukulawula izinga lokushisa nokushisa ngesikhathi sokucubungula futhi uthathe izindlela ezifanele zokupholisa ukunciphisa umphumela wokushintshana okushisayo.
Ama-Burrs nama-Bubble:Izinto zokwakha ipulasitiki eziphezulu zingenagazi futhi zithambekele kuma-burrs nama-bubble. Lokhu kungathinta ukucaca kanye nezakhiwo ze-stickical. Ukuxazulula le nkinga, amapharamitha afanelekile wokuhlonza wokubumba, njengokunciphisa ijubane lomjovo futhi andise izinga lokushisa okubumba, angasetshenziswa ukunciphisa isizukulwane sama-burrs nama-bubble omoya.
Ukuhlwaya okungaphezulu:Izindawo ezisezingeni eliphakeme zepulasitiki zithambekele ekuqhekekeni, okuzothinta umphumela wazo wokubona kanye nekhwalithi yokubukeka. Ukugwema ukuklwebheka komhlaba, kuyadingeka ukusebenzisa izinto ezifanele zokubumba nokubumba ukwelashwa okungaphezulu futhi unake ukuvikela nokwelapha ingaphezulu komkhiqizo ophelile ngesikhathi sokucutshungulwa.
Izakhiwo ezingalinganiKwezinye izimo, ukucutshungulwa kwamapulasitiki acwebezelayo aphezulu kungaholela kwizakhiwo ezingalingani, njengokubonakala kweHaze kanye nombala we-Abrrrration. Ukuxazulula le nkinga, kuyadingeka ukuthi ulawule kahle ikhwalithi yezinto zokwakha, ukucubungula amapharamitha enqubo, kanye nokwelashwa komhlaba okulandelayo ukuze kuqinisekiswe ukufana kwezindawo ezibonakalayo.
Lezi ngezinye zezinselelo ezijwayelekile ezingahle zihlangane phakathi nokucutshungulwa kwamapulasitiki acwebezelayo (ama-optical). Kungenzeka kube nezinye izinkinga ezithile ezidinga ukucatshangelwa futhi zixazululwe ngezinto ezahlukahlukene nezimo ezisebenzayo. Lapho ebhekene nenkinga yokucubungula amapulasitiki acwebezelayo aphezulu, iSilike ithuthukise isengezo se-silicone esiguquliwe esigcina ukuqeda nokuthungwa kwemikhiqizo eluhlaza okotshani ngenkathi kuthuthukisa ukusebenza kwepulasitiki.
Igcina ukuthungwa okuphezulu kakhulu ngaphandle kokuthinta ukuqedwa komkhiqizo - i-silike ukukhethwa kokuqala kokucutshungulwa kwengculazi.
Uchungechunge lwe-Silible SimerUngumkhiqizo onama-polysiloxa ende e-Alkyl-Modified eguquliwe enamaqembu asebenzayo, noma imikhiqizo ye-masterbatch ngokususelwa kuma-resins ahlukene we-thermoplastic. Ngazo zombili izakhiwo ze-silicone namaqembu asebenzayo asebenzayo,Imikhiqizo Silileko Silimerdlala indima enkulu ekucutshungweni kwamapulasitiki nama-elastomers.
Ngokusebenza okuvelele njengokusebenza kahle kokugcotshwa okufuhlayo, ukukhishwa okuhle kwe-solo, inani eliphakeme lokungezwa, ukuhambisana okuhle namapulasitiki, akukho futhi kunciphise ukungqubuzana kokuphikisana, ukuthuthukisa ukumelana komkhiqizo,Imikhiqizo Silileko SilimerIsetshenziselwa kakhulu i-PE, i-PP, i-PVC, i-PBC, i-PBT, PET, AB, PC kanye nezingxenye ezidonswe ngodonga, njll.
Noma kunjalo,Silike Simer 5140, uhlobo lwe-wax ye-silicone wax eguqulwe yi-polyester. Lesi sengezo se-silicone singaba nokuhambisana okuhle nge-resin ebanzi nemikhiqizo yepulasitiki. Futhi igcina ukumelana okuhle kwe-silicone, ngokuqina okuhle okushisayo, kanye nezinzuzo zokuthuthukisa ukusebenza ukuze zilondoloze ukucaciswa kwezinto nokusobala, kungumenzeli we-ejenti ongcono kakhulu, kanye ne-ejenti yokumelana ne-shastrast, kanye ne-agenced yokumelana ne-abrasion kanye ne-abrasist yokumelana ne-agency.
Lapho amapulasitiki angeziwe afanelekile, kuthuthukisa ukucubungula ngokuziphatha okungcono kokukhulisa ukugcwaliswa kokukhishwa, ukugcotshwa okuhle kwangaphakathi, kanye ne-rheology ethuthukisiwe ye-resin incibilike. Ikhwalithi ephezulu ithuthukiswa ukuthuthuka okuthuthukile futhi igqoke ukumelana, i-cof ephansi, i-gloss ephakeme ye-fiber, kanye ne-blass fiber ephakeme, kanye namabhuleki aphansi wefayibha noma amabhuleki aphansi, kusetshenziswa kabanzi kuzo zonke izinhlobo zemikhiqizo ye-thermoplastic.
Ikakhulu,Silike Simer 5140Inikeza ikhambi elisebenzayo lokucubungula le-Plastics (Optical) Plastics PMMA, I-PS, kanye ne-PC, ngaphandle kwanoma yikuphi umbala omubi kumbala wepulasitiki (we-Optical) Plastics 'noma ukucaca.
IngomaneSilike Simer 5140, amazinga okungeziwe aphakathi kuka-0.3 ~ 1.0% aphakanyisiwe. Ingasetshenziswa ngezinqubo ze-Classical Melt ezihlanganisiwe ezifana ne-single / twin isikulufa isikulufa, isikhunda sokujova, nokudla kwaseceleni. Kunconywa ukuhlangana komzimba nge-polymer pellets. Vele, kunamafomula ahlukile ezimo ezihlukile, ngakho-ke sincoma ukuthi uthinte ngqo i-Silike ngqo, futhi sizokunikeza ikhambi elihle kakhulu lokucubungula kwe-thermoplastic nekhwalithi ephezulu!
