Ni ubuhe buryo bukoreshwa mu nganda za selenium?

Inganda za elegitoroniki
Selenium ifite fotosensitivite hamwe na semiconductor, kandi ikoreshwa kenshi mubikorwa bya elegitoronike mugukora fotokeli, fotosensor, ibikoresho bya laser, imashini itwara infragre, fotokeli, fotoreziste, ibikoresho bya optique, fotometer, ikosora, nibindi. hafi 30% y'ibisabwa byose.Seleniyumu isukuye cyane (99,99%) hamwe na seleniyumu ni byo bitangazamakuru nyamukuru bikurura urumuri muri fotokopi, bikoreshwa muri kopi yimpapuro zisanzwe hamwe na fotoreptept ya progaramu ya laser.Ikintu cyingenzi kiranga ibara rya seleniyumu ni uko ifite imiterere ya semiconductor isanzwe kandi irashobora gukoreshwa mugutahura radiyo no kuyikosora.Ikosora rya Selenium ifite ibiranga kurwanya imitwaro, kurwanya ubushyuhe bwinshi no guhagarara neza kwamashanyarazi.

Inganda zikirahure
Selenium ni decolorizer nziza yumubiri kandi ikoreshwa mubikorwa byikirahure.Niba ikirahuri kibisi kirimo ioni yicyuma, ikirahure kizerekana icyatsi kibisi, na selenium nikintu gikomeye gifite urumuri rwinshi, wongeyeho seleniyumu nkeya irashobora gutuma ikirahuri kigaragara nkumutuku, icyatsi nicyatsi gitukura byuzuzanya, bigatuma ikirahuri kitagira ibara, niba seleniyumu ikabije yongeyeho, urashobora gukora ikirahuri kizwi cyane - ikirahuri cya selenium.Selenium nibindi byuma birashobora gukoreshwa hamwe mugutanga ibirahuri amabara atandukanye nkimvi, umuringa nijimye.Ikirahure cy'umukara gikoreshwa mu nyubako no mu modoka nacyo kirimo seleniyumu, igabanya ubukana bw'urumuri n'umuvuduko wo kohereza ubushyuhe.Byongeye kandi, ikirahuri cya seleniyumu nacyo gishobora gukoreshwa mugukora itara ryamatara yumutuku wumutuku ku masangano.

Inganda
Selenium irashobora kunoza imikorere yicyuma, bityo ikoreshwa kenshi mubikorwa byinganda.Ongeramo 0.3-0.5% seleniyumu kugirango ushiremo ibyuma, ibyuma bidafite ingese hamwe nu muringa wumuringa birashobora kunoza imiterere yubukanishi, bigatuma imiterere irushaho kuba mwinshi, kandi hejuru yibice byakozwe neza.Amavuta agizwe na seleniyumu nibindi bintu bikunze gukoreshwa mugukora ibyuma bikosora amashanyarazi make, fotokeli, nibikoresho bya termoelektrike.

Inganda zikora imiti
Selenium n'ibiyigize akenshi bikoreshwa nka catalizator, volcanizers na antioxydants.Gukoresha seleniyumu nka catalizator bifite ibyiza byo kwitwara byoroheje, igiciro gito, kwanduza ibidukikije bike, nyuma yo kuvurwa byoroshye, nibindi. Urugero, seleniyumu yibanze ni umusemburo mugikorwa cyo gutegura sulfure yibanze na sulfite reaction.Mubikorwa byo gukora reberi, seleniyumu ikoreshwa nkumuti wikirunga kugirango wongere imbaraga zo kwambara.

Inganda zita ku buzima
Selenium ni igice cy'ingenzi mu misemburo ya antioxydeant (glutathione peroxidase) na proteyine ya selenium-P mu nyamaswa n'abantu, zishobora guteza imbere ubudahangarwa bw'umuntu, kanseri, indwara zo mu gifu, indwara z'umutima n'imitsi y'ubwonko, indwara za prostate, indwara zo kureba, n'ibindi, bityo selenium ikoreshwa cyane mubuvuzi mu kuvura no kugabanya indwara zitandukanye ziterwa no kubura seleniyumu.Kubera ko seleniyumu ari ikintu gikenewe ku mubiri w'umuntu kandi ikagira ingaruka zikomeye ku buzima bw'abantu, inganda z'ubuzima zatangiye gukora ibicuruzwa bitandukanye byongera seleniyumu, nka malt selenium.

Ibindi Porogaramu
Mu musaruro w’ubuhinzi, seleniyumu irashobora kongerwaho ifumbire kugirango imiterere yubutaka bwa seleniyumu itere imbere kandi biteze imbere gukura kw ibihingwa.Seleniyumu ikoreshwa no kwisiga, kandi amavuta yo kwisiga arimo seleniyumu agira ingaruka zo gusaza.Mubyongeyeho, kongeramo seleniyumu mugisubizo cya plaque birashobora kunoza isura yibice bya plaque, bityo rero ni aYasabye Inganda.
