Ibiranga ibicuruzwa
1.Ibikoresho bya Pc ni iki?
PC. .Guhagarara neza kugirango ushushe, imirasire yumuriro, umwuka na ozone.Irashobora kwinjiza imirasire yose ya ultraviolet iri munsi ya 385nm, ikagira lens nziza.Usibye kurwanya ubushyuhe bwinshi, kurwanya amavuta, amavuta na aside, kwinjiza amazi make, kurwego rwo hejuru rwo guhagarara neza, ni ubwoko bwibikoresho byo kurengera ibidukikije bishobora gukoreshwa inshuro zitabarika.Ibibi ni imihangayiko nini, byoroshye gucika, kutumvikana neza hamwe nandi masigarira, coefficient de fraisse yo hejuru, nta kwisiga.
2.Ibintu nyamukuru biranga lens ya PC:
Weight uburemere
Lens ya PC ifite uburemere bwihariye bwa 1.2, mugihe CR-39 lens ifite uburemere bwihariye bwa 1.32, indangantego 1.56 ifite uburemere bwihariye bwa 1.28, naho ikirahure gifite uburemere bwihariye bwa 2.61.Ikigaragara ni uko mubisobanuro bimwe nubunini bwa geometrike yubunini, lens ya PC, bitewe numubare muto, bikomeza kugabanya uburemere bwinzira.
Inzitizi
Indanganturo ya PC ni 1.591, CR-39 (ADC) indangantego ni 1.499, Indanganturo yo hagati ni 1.553.Urwego rwo hejuru rwerekana indangagaciro ni, ubunini buke ni buke, naho ubundi.Ugereranije na CR39 lens hamwe nubundi buryo bwa resin, PC myopia lens irasa neza.
Umutekano uhebuje
Lens ya PC ifite imbaraga zo kurwanya ingaruka nziza cyane, izwi nka "umwami wa plastike", irashobora gukoreshwa cyane mugukora amadirishya yindege, "ikirahure" kitagira amasasu, masike yimvururu ningabo.Imbaraga zingaruka za PC zigera kuri 87 / kg / cm2, zirenze izo zinc zatewe na aluminium kandi zikubye inshuro 12 izo CR-39.Lens yakozwe na PC ishyirwa kubutaka bwa sima kugirango ikandagire kandi itavunitse, kandi niyo "yonyine itavunitse".Kugeza ubu, lens ya PC ni iya kabiri kuri imwe mu bijyanye n'umutekano.
Sorabsorption ya ultraviolet imirasire
Ubuvuzi bwa kijyambere bwemeje ko urumuri ultraviolet arirwo nyirabayazana w'indwara y'amaso mu maso.Kubwibyo, ibisabwa kugirango ultraviolet yumucyo winjiza lens birasobanutse kandi birasobanutse.Kumurongo rusange wa optique resin, ibikoresho ubwabyo nabyo bifite igice cyimikorere yumucyo wa ultraviolet, ariko niba ushaka gukumira neza urumuri rwa ultraviolet unyuze, ugomba kongeramo umubare munini wumucyo wa ultraviolet mugihe lens ya PC myopia ishobora guhagarika 100% ultraviolet urumuri.
Kurwanya ikirere cyiza
PC nimwe mubintu bya plastiki yubuhanga hamwe nikirere cyiza cyane.Dukurikije imibare yubushakashatsi bwo gusaza karemano yo hanze, imbaraga za tensile, igihu na etiolation ibipimo bya PC ntabwo byahindutse cyane nyuma yo gushyirwa hanze mumyaka 3.
3. Ni irihe tandukaniro riri hagati ya HC, HMC na SHC？
| Igifuniko gikomeye | AR gutwikira / Gukomera cyane | Igikoresho cyiza cya hydrophobique |
| ituma lens idafunze kandi ikongerera abrasion | byongera ihererekanyabubasha kandi bigabanya kugaragara hejuru | ikora lens idafite amazi, antistatike, anti kunyerera no kurwanya amavuta |
