Kushandiswa Kwechigadzirwa
Kushandiswa kwemaindasitiri
Selenium ine zvese photoelectric uye photosensitive zvivakwa.Photoelectric performance inogona kushandura chiedza chakananga kumagetsi, uye photosensitive performance inogona kuderedza kuramba kana ichiwedzera chiedza.Iyo photoelectric uye photosensitive zvimiro zve selenium inogona kushandiswa mukugadzira mafotocells uye exposure metres kumakamera uye masero ezuva.Selenium inogona kushandura ikozvino inochinja kuita yakananga ikozvino, saka inoshandiswa zvakanyanya mukugadzirwa kwezvekugadzirisa.Selenium elemental ndeye P-mhando semiconductor inogona kushandiswa mumaseketi uye yakasimba-nyika zvikamu.Mukuita mafotokopi, selenium inogona kushandiswa kukopa magwaro nemavara (toner cartridges).Muindasitiri yegirazi, selenium inogona kushandiswa kugadzira decolorized girazi, ruby ruvara girazi uye enamel.
Medical giredhi
Boost immune immune
Kudyara kunoshanda selenium kunogona kujekesa mahara radicals mumuviri, kubvisa chepfu mumuviri, antioxidant, inogona kunyatso kuvharidzira kugadzirwa kwe lipid peroxide, kudzivirira kugwamba kweropa, kubvisa cholesterol, uye kuwedzera immune system yemunhu.
Dzivirira chirwere cheshuga
Selenium chinhu chinoshanda che glutathione peroxidase, iyo inogona kudzivirira kuparadzwa kweoxidative yeislet beta masero, kuita kuti ashande zvakajairika, kukurudzira shuga metabolism, kuderedza shuga yeropa uye weti shuga, uye kugadzirisa zviratidzo zvevarwere veshuga.
Kudzivirira cataract
Iyo retina iri panjodzi yekukuvadzwa nekuda kwekunyanya kuratidzwa nemwaranzi yekombuta, selenium inogona kuchengetedza retina, kuwedzera kupera kwemuviri wevitreous, kunatsiridza maziso, uye kudzivirira katarakiti.
