Chimwe chinhu chakakosha chekufunga nezvacho pakusarudza lenzi inyaya yelenzi.
Plastiki ne polycarbonate zvinhu zvinoshandiswa zvakanyanya mukutarisa maziso.
Plastiki yakareruka uye inogara kwenguva refu asi yakakora.
Polycarbonate yakatetepa uye inopa dziviriro yeUV asi inokwenya nyore uye inodhura kupfuura purasitiki.
Lenzi yega yega ine hunhu hwakasiyana hunoita kuti ive yakakodzera kune mamwe mapoka ezera, zvinodiwa uye mararamiro. Pakusarudza lenzi, zvakakosha kufunga nezve:
●Huremu
●Kudzivirira kukanganiswa
●Kudzivirira kukwenya
●Kukora
●Dziviriro yeUltraviolet (UV)
●Mutengo
Pfupiso ye lenzi dzepurasitiki
Magirazi epurasitiki anozivikanwawo seCR-39. Izvi zvave zvichishandiswa zvakanyanya mumaziso kubvira kuma1970 uye zvichiri kufarirwa nevanhu vanopfeka magirazi anonyorerwa nachiremba nekuda kwezvikonzero zvakasiyana-siyana.yayomutengo wakaderera uye kugara kwenguva refu. Kupfeka kunodzivirira kukwenywa, ruvara uye ultraviolet (UV) zvinokwanisa kuwedzerwa nyore nyore kumalenzi aya.
●Huremu hwakareruka –Kana tichienzanisa negirazi rekorona, purasitiki yakareruka. Magirazi ane magirazi epurasitiki akasununguka kupfeka kwenguva yakareba.
●Kujeka kwakanaka kwemaziso –Magirazi epurasitiki anopa kujeka kwakanaka kwemaziso. Haakonzeri kukanganisa kwakanyanya kuona.
●Inogara kwenguva refu –Magirazi epurasitiki haawanzo pwanyika kana kupwanyika segirazi. Izvi zvinoita kuti ave sarudzo yakanaka kune vanhu vanoshanda nesimba, kunyange zvazvo asingapwanyike sepolycarbonate.
●Hazvidhuri zvakanyanya –Magirazi epurasitiki anowanzo kudhura zvishoma pane polycarbonate.
●Kudzivirira zvishoma UV –Purasitiki haingodziviriri zvishoma kubva kumwaranzi yeUV inokuvadza. Pendi yeUV inofanira kuwedzerwa kuti idzivirire zvizere kana uchironga kupfeka magirazi panze.
Pfupiso ye lenzi dze polycarbonate
Polycarbonate imhando yepurasitiki inodzivirira kukuvadzwa zvakanyanya inoshandiswa mumaziso. Magirazi ekutanga e polycarbonate ekutengeserana akaunzwa muma1980, uye akakurumidza kukura mukurumbira.
Lenzi iyi inodzivirira kukuvadzwa kakapetwa kagumi kupfuura purasitiki. Nekuda kweizvi, inowanzo kurudzirwa kuvana nevakuru vanoshanda.
●Inogara kwenguva refu –Polycarbonate chimwe chezvinhu zvakasimba uye zvakachengeteka zvinoshandiswa mumagirazi mazuva ano. Inowanzo kurudzirwa kuvana vadiki, vakuru vanoshanda, uye vanhu vanoda kuchengetedzwa kwemaziso.
●Mutete uye wakareruka –Magirazi epolycarbonate akatetepa kusvika 25 muzana kupfuura epurasitiki yechinyakare.
●Dziviriro yeUV yese -Polycarbonate inovhara mwaranzi yeUV, saka hapana chikonzero chekuwedzera UV coating mumagirazi ako. Magirazi aya sarudzo yakanaka kune vanhu vanopedza nguva yakawanda vari panze.
●Kupfeka kunodzivirira kukwenywa kunokurudzirwa -Kunyangwe polycarbonate yakasimba, jira racho richiri nyore kukwenya. Kupfeka kusingakwenye kunokurudzirwa kuti magirazi aya agare kwenguva refu.
●Kupfeka kunodzivirira kufungisisa kunokurudzirwa –Vamwe vanhu vane mishonga yepamusoro vanoona kupenya kwepadenga uye kupenya kwemavara pavanenge vakapfeka magirazi epolycarbonate. Kupfeka kunodzivirira kupenya kunokurudzirwa kuderedza izvi.
●Kuona kwakakanganisika –Polycarbonate inogona kukonzera kusaona zvakanaka kwemaziso kune avo vane mishonga yakasimba.
●Zvinodhura zvakanyanya -Magirazi epolycarbonate anowanzo kudhura kupfuura magirazi epurasitiki.
Unogona kuwana dzimwe sarudzo dzezvinhu zvemalenzi uye mabasa awo nekutsvaga webhusaiti yeduhttps://www.universeoptical.com/stock-lens/Kana muine mibvunzo, munogamuchirwa kutibata kuti muwane rumwe ruzivo.
