Ndiko kumangoyamba koyamba kungawoneke kuti kusankha magalasi ku dzuwa ndi kosavuta komanso kosagwirizana ndi chisankho: "Kupita" kapena "sikupita." Ndipotu, ndikofunika kumangoganizira kwambiri za makhalidwe akunja, komanso, ndithudi, ku khalidwe. Ndicho chifukwa chake, poganizira momwe mungathetsere vutoli, momwe mungasankhire magalasi okhala ndi magalasi abwino, fesitista silingaganizire mfundo zingapo zosavuta.
Makhalidwe atatu a khalidwe pakusankha magalasi
Kotero, momwe mungadziwire ubwino wa magalasi a magalasi - mtsikanayo adzifunse yekha, akukonzekera kuyamba kwa nyengo ya dzuwa ndipo panthawi imodzimodziyo akuyandikira mosankhidwa kusankha izi. Akatswiri amalangiza chidwi pa zinthu zingapo zofunika, kuphatikizapo:
- zinthu zomwe makalenti amapangidwa;
- mlingo wotetezedwa ku dzuwa;
- bezel bwino.
Inde, mndandandawu ukhoza kupitilizidwa ndi zizindikiro zina, koma, mwinamwake, mfundo zitatu izi zidzakupatsani yankho lenileni ku funso la momwe mungayang'anire mtundu wa magalasi.
Magalasi abwino samatha kusokonezeka ndi chirichonse!
Malenti, monga amadziŵika, amachokera ku galasi ndi pulasitiki, zomwe zingakhale zotsika mtengo komanso zodula. Mwachiwonekere, magalasi a magalasi amathandiza kwambiri maso chifukwa chakuti amasonyeza kuwala. Komabe, mtengo wawo nthawi zambiri ndi wokwanira. Mitengo yowonjezereka ya demokarasi ndizochokera ku pulasitiki yamtengo wapatali - polycarbonate. Mtundu wa magalasi oterewa ndi wamtengo wapatali, mosiyana ndi zipangizo zamapulasitiki zopanda phindu zochokera ku China zomwe zimapanga majekesi amdima, omwe sungateteze maso ku dzuwa, komanso amachititsa kuti maso asawonongeke, chifukwa, osakhoza kulimbana ndi mphamvu ya ultraviolet, ophunzira a mavuto akukula. Polycarbonate, monga chuma, ndi othandiza kwambiri pa masomphenya pambali iyi, komabe, pakapita nthawi, zowonongeka ndi zowonongeka zimapezekabe.
Mu njira yowunika magalasi a magalasi kuti akhale abwino, osati gawo laling'ono likusewera ndi mlingo wa chitetezo ku dzuwa. Zoonadi, chilembachi chili m'masitolo apadera, kumene magalasi apamwamba ndi magalasi a magalasi amaperekedwa. Zonsezi zili ndi zizindikiro ziwiri: yoyamba ndi digete yapamwamba yotetezedwa imatchedwa "UV-A", yachiwiri yomwe ili ndi chiwerengero cha chitetezo chimatchedwa "UV-B". Magalasi abwino apamwamba pa chizindikiro choyamba ayenera kusankhidwa kwa okondedwa achilimwe pamphepete mwa nyanja ndi okonda tani.
Potsirizira pake, mphutsi ndi chinthu china chosiyanitsa cha magalasi apamwamba. Choyamba, izi ziyenera kukhala zabwino komanso osamvetsetseka pamsewu wa mphuno kapena vuto lililonse. Chabwino, pamene nthiti yomwe ili kumtunda wapamwamba imabwereza mawonekedwe a mzere wa nsidze. Koma mtundu wake ndi mawonekedwe ake, ndiye zonse zimadalira zofuna za fesitista. Kupatula imodzi "koma": magalasi okwera mtengo kwambiri, monga lamulo, amapereka mawonekedwe apangidwe a mafelemu, opanda ziboliboli ndi zinthu zina zokongoletsa.
