Amapulasitiki acwebezela kakhulu (optical) ngokuvamile abhekisela ezintweni zepulasitiki ezinezakhiwo ezinhle kakhulu zokubona, futhi izinto ezivamile zihlanganisa i-polymethylmethacrylate (PMMA), i-polycarbonate (PC), ne-polystyrene (PS). Lezi zinto zingase zibe nokukhanyela okuhle kakhulu, ukumelana nokuklwebheka, nokufana kokubona ngemuva kokwelashwa okukhethekile.
Amapulasitiki acwebezelayo asetshenziswa kakhulu emikhakheni ehlukahlukene ye-optical, njengamalensi engilazi yamehlo, amalensi ekhamera, izibani zezibani zemoto, izikrini zefoni ephathekayo, amaphaneli okuqapha, njalonjalo. Ngenxa yokubonakala kwayo okuhle kakhulu kanye nezakhiwo ze-optical, amapulasitiki acwebezelayo angakwazi ukudlulisa ukukhanya ngokuphumelelayo futhi anikeze imiphumela ecacile ebonakalayo, kuyilapho futhi evikela amadivayisi angaphakathi endaweni yangaphandle. Sekukonke, amapulasitiki acwebezelayo aphezulu anezinhlobonhlobo zezicelo ekwenziweni kwemishini yokubona, amagobolondo emikhiqizo ye-elekthronikhi, izinto zokwakha, neminye imikhakha, futhi indima yawo ikakhulukazi ukuhlinzeka ngokusebenza okuhle nokuvikeleka, kodwa futhi nokwenza kube muhle ukubukeka umkhiqizo.
Ezinye zezinselelo nezingqinamba ezingase kuhlangatshezwane nazo ngesikhathi kulungiswa amapulasitiki acwebezelayo (optical) ahlanganisa lokhu okulandelayo:
I-Thermal deformation:Amanye amapulasitiki acwebezela kakhulu athambekele ekuwohlokeni kokushisa ngesikhathi senqubo yokushisisa, okuholela ekuhlanekeni kosayizi noma ukuma komkhiqizo oqediwe. Ngakho-ke, kuyadingeka ukulawula izinga lokushisa kanye nesikhathi sokushisa ngesikhathi sokucubungula futhi uthathe izindlela zokupholisa ezifanele ukuze unciphise umphumela wokushisa okushisayo.
Amabhamu namabhamuza:Izinto zepulasitiki ezicwebezelayo eziphakeme ziba brittle futhi zithambekele ekubeni nama-burrs namabhamuza. Lokhu kungase kuthinte ukucaca kanye nezakhiwo zokubona. Ukuxazulula le nkinga, imingcele yenqubo yokubumba yomjovo efanelekile, njengokwehlisa isivinini somjovo nokwandisa izinga lokushisa lokukhunta, ingasetshenziswa ukunciphisa ukukhiqizwa kwamabhamuza namabhamuza omoya.
Imihuzuko ebusweni:Izindawo zepulasitiki ezicwebezelayo ziyakwazi ukuklwebheka, okuzothinta umphumela wazo wokubona kanye nekhwalithi yokubukeka. Ukuze ugweme imihuzuko engaphezulu, kuyadingeka ukusebenzisa izinto ezifanele zokubumba kanye nokwelashwa kwendawo yokubumba futhi unake ukuvikela nokwelapha ubuso bomkhiqizo oqediwe ngesikhathi sokucubungula.
Izici ze-Optical ezingalingani:Kwezinye izimo, ukucutshungulwa kwamapulasitiki acwebezele kakhulu kungase kuholele ezintweni ezingalingani zokubona, njengokuvela kwenkungu nokugqama kombala. Ukuze uxazulule le nkinga, kuyadingeka ukulawula ngokuqinile ikhwalithi yezinto zokusetshenziswa, imingcele yenqubo yokucubungula, nokwelashwa okulandelayo kwendawo ukuze kuqinisekiswe ukufana kwezakhiwo ze-optical.
Lezi ezinye zezinselele ezivamile ezingase zihlangatshezwe ngesikhathi sokucubungula amapulasitiki acwebezelayo (optical) aphezulu. Kungase kube nezinye izinkinga ezithile ezidinga ukucatshangelwa futhi zixazululwe ngezinto ezihlukene nezimo ezingokoqobo. Lapho ibhekene nenkinga yokucubungula amapulasitiki acwebezele kakhulu, i-SILIKE ithuthukise isengezo esilungisiwe se-silicone esigcina isiphetho nokuthungwa kwemikhiqizo yepulasitiki ecwebezelayo ngenkathi futhi ithuthukisa ukusebenza kokucubungula.
Igcina ukuthungwa okucwebezelayo okuphezulu ngaphandle kokuthikameze ukuphela komkhiqizo——I-SILIKE iyinketho yokuqala yezinsiza zokucubungula.
SILIKE SILIMER uchungechungeiwumkhiqizo onochungechunge olude lwe-alkyl-modified polysiloxane enamaqembu asebenzayo asebenzayo, noma imikhiqizo ye-masterbatch esekelwe kuma-resin ahlukene we-thermoplastic. Ngazo zombili izakhiwo ze-silicone namaqembu asebenzayo asebenzayo,SILIKE SILIMER imikhiqizodlala indima enkulu ekucutshungulweni kwamapulasitiki nama-elastomers.
Ngokusebenza okuvelele okufana nokusebenza kahle kokugcotshwa okuphezulu, ukukhishwa okuhle kwe-solo, inani elincane lokwengeza, ukuhambisana okuhle namapulasitiki, akukho mvula, futhi kunganciphisa kakhulu i-coefficient yokungqubuzana, kuthuthukise ukumelana nokugqoka kanye nokumelana nokuklwebheka kwendawo yomkhiqizo,SILIKE SILIMER imikhiqizoasetshenziswa kabanzi ku-PE, PP, PVC, PBT, PET, ABS, PC kanye nezingxenye ezinodonga oluncane, njll.
Nokho,SILIKE SILIMER 5140, luhlobo lwe-silicone wax eguqulwa nge-polyester. lesi sengezo se-silicone singahambisana kahle nemikhiqizo eminingi ye-resin nepulasitiki. futhi igcina ukumelana nokugqokwa okuhle kwe-silicone, ngokuzinza okuhle kokushisa, kanye nezinzuzo ezithuthukisa ukusebenza ukuze kugcinwe ukucaca kwempahla nokungafihli lutho, iyi-lubricant yangaphakathi enhle kakhulu, i-ejenti yokukhulula, kanye ne-ejenti engaklwebhi kanye ne-abrasion yokucubungula ipulasitiki.
Uma amapulasitiki engeziwe afanelekile, athuthukisa ukucutshungulwa ngokuziphatha okungcono kokugcwalisa isikhunta, ukuthambisa okuhle kwangaphakathi, kanye ne-rheology ethuthukisiwe yokuncibilika kwe-resin. ikhwalithi yangaphezulu ithuthukiswa ngokuthuthukiswa kokuqina nokumelana nokugqoka, i-COF ephansi, isicwebezelisi esiphezulu, kanye nokumanzisa okungcono kwe-fiber yengilazi noma amabhuleki e-fiber aphansi, Isetshenziswa kabanzi kuzo zonke izinhlobo zemikhiqizo ye-thermoplastic.
Ikakhulukazi,SILIKE SILIMER 5140ihlinzeka ngesixazululo esisebenzayo sokucubungula amapulasitiki acwebezelayo (optical) we-PMMA, i-PS, ne-PC, ngaphandle kwanoma yimuphi umthelela omubi kumbala noma ukucaca okucwebezelayo (okubonakalayo) kwamapulasitiki.
NgobaSILIKE SILIMER 5140, amazinga okungeza aphakathi kuka-0.3~1.0% ayaphakanyiswa. Ingasetshenziswa ezinqubweni zokuhlanganisa zokuncibilika kwe-classical ezifana nezikhiphi zezikulufi eziSingle/Twin, ukubumba umjovo, nokuphakelayo okuseceleni. Kunconywa inhlanganisela engokwenyama namapellets e-polymer emsulwa. Yebo, kukhona amafomula ahlukene ezimo ezihlukene, ngakho-ke sincoma ukuthi uxhumane no-SILIKE ngokuqondile, futhi sizokunikeza isisombululo esingcono kakhulu sokucutshungulwa kwe-thermoplastic kanye nekhwalithi ephezulu!
