Ziziphi iindlela zokusetyenziswa kwe-selenium kwimizi-mveliso?
Ishishini le-elektroniki
I-Selenium ineempawu ze-photosensitivity kunye ne-semiconductor, kwaye isetyenziswa rhoqo kwishishini le-elektroniki ukwenza ii-photocells, ii-photosensors, izixhobo ze-laser, ii-infrared controllers, ii-photocells, ii-photoresistor, izixhobo ze-optical, ii-photometers, ii-rectifiers, njl. Ukusetyenziswa kwe-selenium kwishishini le-elektroniki kwenza malunga ne-30% yemfuno iyonke. I-selenium ecocekileyo kakhulu (99.99%) kunye nee-selenium alloys zezona zinto ziphambili ezifunxa ukukhanya kwii-photocopiers, ezisetyenziswa kwii-copiers zephepha ezicacileyo kunye nee-photoreceptors kwii-laser presses. Uphawu olubalulekileyo lwe-selenium engwevu kukuba ineempawu eziqhelekileyo ze-semiconductor kwaye ingasetyenziselwa ukufumanisa kunye nokulungisa amaza erediyo. I-Selenium rectifier ineempawu zokumelana nomthwalo, ukumelana nobushushu obuphezulu kunye nokuzinza okuhle kombane.
Imboni yeglasi
I-Selenium sisixhobo esihle sokususa umbala emzimbeni kwaye sisetyenziswa rhoqo kwishishini leglasi. Ukuba izinto eziluhlaza zeglasi ziqulethe ii-ion zesinyithi, iglasi iya kubonisa uluhlaza olukhanyayo, kwaye i-selenium yinto eqinileyo ene-metallic luster, ukongeza inani elincinci le-selenium kunokwenza iglasi ibonakale ibomvu, iluhlaza kwaye ibomvu ihambelana, yenze iglasi ingabi nambala, ukuba i-selenium egqithisileyo yongezwa, ungenza iglasi edumileyo yeruby - iglasi yeselenium. I-Selenium kunye nezinye izinyithi zingasetyenziswa kunye ukunika iglasi imibala eyahlukeneyo efana nongwevu, ubhedu kunye nepinki. Iglasi emnyama esetyenziswa kwizakhiwo nakwiimoto ikwanayo neselenium, enciphisa ubukhali bokukhanya kunye nesantya sokudluliselwa kobushushu. Ukongeza, iglasi yeselenium ingasetyenziselwa ukwenza isibane sesibane sesibane esibomvu sesignali kwindawo edibana kuyo.
Ishishini lesinyithi
I-Selenium inokuphucula ukusebenza kakuhle kwentsimbi, ngoko ke isetyenziswa rhoqo kushishino lwesinyithi. Ukongeza i-0.3-0.5% ye-selenium kwisinyithi esitshisiweyo, intsimbi engatyiwayo kunye nee-alloys zobhedu kunokuphucula iimpawu zazo zoomatshini, kwenze isakhiwo sibe xineneyo, kwaye umphezulu weendawo ezisetyenzisiweyo ube mpuluswa ngakumbi. Ii-alloys ezenziwe nge-selenium kunye nezinye izinto zihlala zisetyenziswa ekwenzeni ii-rectifiers ze-low-voltage, ii-photocells, kunye nezinto ze-thermoelectric.
Ishishini leekhemikhali
I-Selenium kunye neekhompawundi zayo zihlala zisetyenziswa njengee-catalysts, ii-vulcanizers kunye nee-antioxidants. Ukusetyenziswa kwe-selenium njenge-catalyst kuneengenelo zeemeko zokusabela okuncinci, iindleko eziphantsi, ungcoliseko oluncinci lokusingqongileyo, unyango olulula emva koko, njl. Umzekelo, i-selenium ye-elemental yi-catalyst kwinkqubo yokulungiselela i-elemental sulfur nge-sulfite reaction. Kwinkqubo yokuvelisa irabha, i-selenium isetyenziswa rhoqo njenge-agent ye-vulcanizing ukuphucula ukumelana nokuguguleka kwerabha.
Ishishini lezempilo
I-Selenium yinxalenye ebalulekileyo yee-enzymes ezithile ze-antioxidant (i-glutathione peroxidase) kunye neproteni ye-selenium-P kwizilwanyana nakubantu, enokuphucula amasosha omzimba womntu, umhlaza, izifo zesisu, izifo zentliziyo kunye nemithambo yegazi, izifo ze-prostate, izifo zokubona, njl.njl., ngoko ke i-selenium isetyenziswa kakhulu kwicandelo lezonyango kunyango kunye nokunciphisa izifo ezahlukeneyo ezibangelwa kukungabikho kwe-selenium. Ekubeni i-selenium iyinto ebalulekileyo emzimbeni womntu kwaye inempembelelo ebalulekileyo kwimpilo yabantu, ishishini lezempilo liqalise ukuphuhlisa iimveliso ezahlukeneyo ze-selenium, ezifana ne-selenium ye-malt.
Ezinye izicelo
Kwimveliso yezolimo, i-selenium ingongezwa kwisichumisi ukuphucula imeko yokunqongophala kwe-selenium emhlabeni kunye nokukhuthaza ukukhula kwezityalo. I-Selenium ikwasetyenziswa kwizinto zokuthambisa, kwaye ezinye izinto zokuthambisa ezine-selenium zinefuthe lokulwa nokwaluphala. Ukongeza, ukongeza i-selenium kwisisombululo sokuthambisa kunokuphucula ukubonakala kweendawo zokuthambisa, ngoko ke ikwayintoisetyenziswe kwishishini lokufaka iipleyiti.
