1.49 CR39 Semi-yarangije kwerekanwa Lens Blanks
Niki Semi Yarangije Lens Blanks ishobora gukora?
Spectacle lens ibice bitanga umusaruro uhindura igice cya kabiri cyarangije guhinduka muburyo bwuzuye buranga imiti.
Igikorwa cyo kwihitiramo laboratoire kidushoboza gutanga itandukaniro ryinshi rya optique ikomatanya kubantu bambara, cyane cyane kubijyanye no gukosora presbyopiya. Laboratoire zifite inshingano zo kugaragara (gusya no gusya) no gutwikira (amabara, anti-scratch, anti-reflive, anti-smudge nibindi) lens.
Kuki Guhitamo CR-39 Amashanyarazi?
Crystal Vision (CR) ninziza zo mu rwego rwo hejuru zakozwe na imwe mu masosiyete akomeye ku isi.
CR-39, cyangwa allyl diglycol karubone (ADC), ni polymer ya plastike ikunze gukoreshwa mugukora indorerwamo z'amaso.
Amagambo ahinnye yerekana “Columbia Resin # 39”, yari formula ya 39 ya plastike ya termosetting yakozwe n'umushinga wa Columbia Resins mu 1940.
Ufitwe na PPG, ibi bikoresho birahindura gukora lens.
Kimwe cya kabiri kiremereye nkikirahure, ntibishoboka cyane kumeneka, hamwe nubwiza bwa optique hafi nkikirahure.
CR-39 irashyuha hanyuma igasukwa muburyo bwiza bwikirahure - guhuza imiterere yikirahure cyane.
a) Ubukungu
b) Umucyo
c) Kurwanya kumeneka
d) Irashobora gushushanya & gutwikirwa
e) Kurinda UV
Lens yubusa ni iki?
Lens yubuntu isanzwe ifite ubuso bwimbere hamwe nubuso bugoye, butatu-buringaniye bwinyuma burimo ibyo umurwayi yandikiwe. Kubireba lens yubusa igenda itera imbere, inyuma ya geometrie yinyuma harimo igishushanyo mbonera.
Inzira yubuntu ikoresha igice cyarangiye cya serefegitura iboneka byoroshye mugice kinini cyimirongo ifatika. Izi lens zakozwe neza kuruhande rwinyuma hifashishijwe ibikoresho bigezweho bibyara kandi bisya kugirango bikore neza neza.
• ubuso bwimbere ni ubuso bworoshye
• ubuso bwinyuma nubuso butatu buringaniye
Ikoranabuhanga kubuntu
• Itanga uburyo bworoshye bwo gutanga ibicuruzwa byinshi murwego rwo hejuru, ndetse no muri laboratoire ntoya
• Birasaba gusa ikigega cya kimwe cya kabiri kirangiye muri buri kintu kiva ahantu hose
• Imicungire ya laboratoire yoroshye hamwe na SKU nkeya
• Ubuso butera imbere bwegereye ijisho - butanga imirima yagutse yo kureba muri koridor no gusoma
• Yerekana neza igishushanyo mbonera cyagenewe gutera imbere
• Kwandika neza ntabwo bigarukira gusa ku ntambwe zikoreshwa muri laboratoire
• Guhuza inyandiko neza byemewe
