Aluminium akuphika kalirilo wa nyali
Mafotokozedwe Akatundu
Miyala yamtunduwu nthawi zambiri imagwiritsidwa ntchito ngati nyali mu ophthalmology kuti ipereke chithunzi chomveka bwino komanso cholondola cha wodwala. Aluminiyam yophimba pagalasi yoyaka yoyaka imagwira ntchito ngati mawonekedwe owoneka bwino, kulola kuunika kuti utumizidwe m'malo osiyanasiyana kudzera mwa wophunzirayo kudzera mwa wodwalayo.
Kuphika kwa aluminiyamu kumagwiritsidwa ntchito kudzera mu njira yotchedwa vacuum kuphatikizika. Izi zimaphatikizapo kutentha aluminiyamu m'chipinda chopumira, kupangitsa kuti lituluke kenako ndikulekanitsa pamwamba pagalasi. Kukula kwa zosemphana kumatha kuwongolera kuti tiwonetsetse bwino zinthu komanso kulimba.
Mahala a aluminium aluminium amakopeka ndi mitundu ina yamagalasi yopaka nyali chifukwa amakhala ndi mawonekedwe apamwamba, amalimbana ndi kuwonongeka ndi abrasion, komanso wopepuka. Chowoneka chowoneka bwino chagalasi chimafunikira kusungidwa bwino, chifukwa chake, chisamaliro chiyenera kumwedwa kuti musakande kapena kuwononga galasi patsogolo pakugwiritsa ntchito kapena kuyeretsa.
Nyali yocheperako ndi chida chofunikira chomwe ophthalmologis amagwiritsa ntchito. Nyali yotsika imalola madokotala kuti awerenge mbali zosiyanasiyana za diso, monga momwe timakondera, iris, mandala, ndi retina. Chimodzi mwazinthu zofunika kwambiri za nyali zowoneka bwino ndiye galasi, lomwe limagwiritsidwa ntchito kupereka chithunzi chomveka bwino. Makamaka magalasi okutidwa ndi aluminim achita kutchuka m'zaka zaposachedwa chifukwa cha maluso awo apamwamba komanso kulimba.
Galasi yolumitsidwa ndi galasi yapamwamba yopangidwa ndi galasi. Galasi limaphimbidwa ndi woonda wosanjikiza wa aluminium, ndikupereka mawonekedwe owonjezera owonjezera komanso owoneka bwino. Galasi linapangidwa kuti liziikidwa mu nyali yoyaka, pomwe imawala kuunika ndi zifaniziro kuchokera kumaso. Aluminium yophimba pagalasi imapereka chithunzithunzi chokwanira cha kuwala, kuonetsetsa kuti chithunzicho chimamveka komanso chowala.
Chimodzi mwazinthu zopondera za magalasi a chilumi omwe amalimbana nawo. Galasi limapangidwa ndi zida zapamwamba kwambiri zotha kuwonongeka ndi zingwe zathupi, zikanda, ndi mankhwala. Kagalasi adapangidwa kuti azitha kupirira ziwopsezo za kugwiritsa ntchito tsiku ndi tsiku, ndikupangitsa kukhala gawo lodalirika komanso lokwera mtengo wa nyali yotsika.
Wogalasi wokutidwa ndi aluminium amaperekanso kusiyana. Kuwoneka bwino kwagalasi kumapangitsa ophthalmogists kuti akawone zambiri za maso momveka bwino, zimapangitsa kuti zikhale zosavuta kuzindikira matenda amiyeso. Chifukwa cha ntchito yake yapamwamba kwambiri, magalasi okhala ndi aluminium okhala ndi chida chofunikira kwa ophthalmologists mu matenda ndi chithandizo.
Mwachidule, kalirole wopangidwa-wopangidwa ndi aluminium ndi gawo lofunikira la nyali yosenda, ndikupatsa ophthalmogists okhala ndi zithunzi zakumaso. Zida zapamwamba zomwe zimagwiritsidwa ntchito pomanga galasi zimapangitsa kuti zikhale zodalirika komanso zolimba, kuonetsetsa kuti zitha kupirira zovuta za kugwiritsa ntchito tsiku ndi tsiku. Kuchita kwake kwakukulu komanso kukhazikika kwake kwakukulu kumapangitsa kuti chikhale ndalama yabwino kwambiri ya ophthalmosy yomwe ikufuna kuwonjezera luso lawo.
