Ndezvipi zvinoshandiswa muindasitiri zve selenium?

Indasitiri yezvemagetsi
Selenium ine photosensitivity uye semiconductor properties, uye inowanzoshandiswa muindasitiri yemagetsi kugadzira ma photocells, ma photosensors, laser devices, infrared controllers, ma photocells, photoresistor, optical instruments, ma photometers, rectifiers, nezvimwewo. Kushandiswa kweselenium muindasitiri yemagetsi kunoita 30% yehuwandu hwese hunodiwa. Selenium yakachena (99.99%) uye selenium alloys ndiyo inonyanya kupinza chiedza muma photocopiers, anoshandiswa muma plain paper copiers nema photoreceptors e laser presses. Chinhu chakakosha che grey selenium ndechekuti ine ma semiconductor properties akajairika uye inogona kushandiswa pakuona uye kugadzirisa radio wave. Selenium rectifier ine hunhu hwe resistance load, resistance high tembiricha uye kugadzikana kwakanaka kwemagetsi.

Indasitiri yegirazi
Selenium imhando yakanaka yekubvisa ruvara uye inowanzoshandiswa muindasitiri yegirazi. Kana girazi riine ma iron ions, girazi richaratidza girini rakareruka, uye selenium yakasimba ine simbi inopenya, kuwedzera selenium shoma kunogona kuita kuti girazi riite sedzvuku, girini netsvuku zvienderane, zvichiita kuti girazi risave neruvara, kana selenium yakawandisa ikawedzerwa, unogona kugadzira girazi rine ruby ​​rakakurumbira - selenium girazi. Selenium nedzimwe simbi dzinogona kushandiswa pamwe chete kupa girazi mavara akasiyana akadai segrey, bronze nepingi. Girazi dema rinoshandiswa muzvivakwa nemota rinewo selenium, iyo inoderedza simba rechiedza uye kumhanya kwekupisa. Pamusoro pezvo, girazi reselenium rinogonawo kushandiswa kugadzira rambi remwenje wechiratidzo chechiedza chitsvuku panzvimbo inoungana.

Indasitiri yesimbi
Selenium inogona kuvandudza kushanda kwesimbi, saka inowanzoshandiswa muindasitiri yesimbi. Kuwedzera selenium 0.3-0.5% musimbi yakakandwa, simbi isingatsvi uye alloys dzemhangura kunogona kuvandudza mashandiro adzo emuchina, kuita kuti chimiro chive chakasimba, uye pamusoro pezvikamu zvakagadzirwa nemuchina zvive zvakapfava. Alloys inoumbwa neselenium nezvimwe zvinhu zvinowanzo shandiswa mukugadzira zvinogadzirisa magetsi zvishoma, ma photocell, uye zvinhu zvinopisa.

Indasitiri yemakemikari
Selenium nezvinhu zvayo zvinowanzo shandiswa se catalysts, vulcanizers uye antioxidants. Kushandiswa kweselenium se catalyst kune zvakanakira mamiriro ekuita zvinyoro nyoro, mutengo wakaderera, kusvibiswa kwezvakatipoteredza kushoma, nyore kurapwa mushure mekurapwa, nezvimwewo. Semuenzaniso, elemental selenium ndiyo catalyst mukugadzirira elemental salfa ne sulfite reaction. Mukugadzirwa kwerabha, selenium inowanzo shandiswa se vulcanizing agent yekuwedzera kuramba kwerabha.

Indasitiri yehutano
Selenium chikamu chakakosha chemamwe ma enzymes e antioxidant (glutathione peroxidase) uye selenium-P protein mumhuka nevanhu, izvo zvinogona kuvandudza dziviriro yemuviri yevanhu, kenza, zvirwere zvemudumbu, zvirwere zvemwoyo netsinga dzeropa, zvirwere zveprostate, zvirwere zvekuona, nezvimwewo, saka selenium inoshandiswa zvakanyanya mukurapa nekuderedza zvirwere zvakasiyana-siyana zvinokonzerwa nekushaikwa kwe selenium. Sezvo selenium iri chinhu chinodiwa mumuviri wemunhu uye iine simba guru pahutano hwevanhu, indasitiri yehutano yakatanga kugadzira zvigadzirwa zvakasiyana-siyana zve selenium, zvakaita se malt selenium.

Mamwe maapplication
Mukurima, selenium inogona kuwedzerwa kufetereza kuti ivandudze mamiriro ekushomeka kwe selenium muvhu uye kukurudzira kukura kwezvirimwa. Selenium inoshandiswawo muzvizoro, uye zvimwe zvizoro zvine selenium zvine simba rekudzivirira kukwegura. Pamusoro pezvo, kuwedzera selenium mumushonga wekuisa plating kunogona kuvandudza chitarisiko chezvikamu zveplating, saka zvakare ibasa reinoshandiswa kuindasitiri yekupenda.
