Kodi ntchito za selenium m'mafakitale ndi ziti?
Makampani a zamagetsi
Selenium ili ndi mphamvu zowunikira kuwala komanso mphamvu zowunikira kuwala, ndipo nthawi zambiri imagwiritsidwa ntchito mumakampani opanga ma photocell, ma photosensor, zida za laser, ma infrared controller, ma photocell, ma photoresistor, zida zowunikira, ma photometer, ma rectifier, ndi zina zotero. Kugwiritsa ntchito selenium mumakampani opanga ma elekitironi kumafikira pafupifupi 30% ya kufunikira konse. Selenium yoyera kwambiri (99.99%) ndi selenium alloys ndizomwe zimayamwa kuwala kwambiri mu ma photocopiers, zomwe zimagwiritsidwa ntchito mu ma copiers a pepala wamba ndi ma photoreceptors a laser presses. Chinthu chofunikira cha selenium imvi ndichakuti ili ndi mphamvu zowunikira kuwala ndipo ingagwiritsidwe ntchito pozindikira ndi kukonza mafunde a wailesi. Selenium rectifier ili ndi mphamvu zotsutsana ndi katundu, kukana kutentha kwambiri komanso kukhazikika bwino kwamagetsi.
Makampani agalasi
Selenium ndi chinthu chabwino chochotsera utoto ndipo nthawi zambiri chimagwiritsidwa ntchito mumakampani opanga magalasi. Ngati galasi lili ndi ayoni achitsulo, galasilo lidzawonetsa zobiriwira zopepuka, ndipo selenium ndi yolimba yokhala ndi kunyezimira kwachitsulo, kuwonjezera selenium pang'ono kungapangitse galasilo kuoneka lofiira, lobiriwira ndi lofiira kuti ligwirizane, kupangitsa galasi kukhala lopanda utoto, ngati selenium yochulukirapo yowonjezeredwa, mutha kupanga galasi lodziwika bwino la ruby - selenium galasi. Selenium ndi zitsulo zina zitha kugwiritsidwa ntchito pamodzi kuti zipatse magalasi mitundu yosiyanasiyana monga imvi, bronze ndi pinki. Galasi lakuda lomwe limagwiritsidwa ntchito m'nyumba ndi m'magalimoto lilinso ndi selenium, yomwe imachepetsa mphamvu ya kuwala ndi liwiro la kusamutsa kutentha. Kuphatikiza apo, galasi la selenium lingagwiritsidwenso ntchito kupanga nyali ya nyali yofiira ya chizindikiro pamalo olumikizirana.
Makampani opanga zitsulo
Selenium imatha kupititsa patsogolo kugwira ntchito kwa chitsulo, kotero nthawi zambiri imagwiritsidwa ntchito m'makampani opanga zitsulo. Kuwonjezera selenium ya 0.3-0.5% ku chitsulo chosungunuka, zitsulo zosapanga dzimbiri ndi zitsulo zamkuwa kungathandize kukonza mphamvu zawo zamakaniko, kupangitsa kapangidwe kake kukhala kolimba, komanso pamwamba pa ziwalo zopangidwa ndi makinawo kukhala posalala. Ma alloy opangidwa ndi selenium ndi zinthu zina nthawi zambiri amagwiritsidwa ntchito popanga ma rectifiers otsika mphamvu, ma photocell, ndi zinthu zotentha.
Makampani opanga mankhwala
Selenium ndi mankhwala ake nthawi zambiri amagwiritsidwa ntchito ngati ma catalyst, vulcanizers ndi ma antioxidants. Kugwiritsa ntchito selenium ngati catalyst kuli ndi ubwino wa zinthu zochepetsera kukhudzana, mtengo wotsika, kuipitsa chilengedwe pang'ono, kuchira msanga, ndi zina zotero. Mwachitsanzo, elemental selenium ndiye catalyst pokonzekera elemental sulfure ndi sulfite reaction. Pakupanga rabala, selenium nthawi zambiri imagwiritsidwa ntchito ngati vulcanizing agent kuti iwonjezere kukana kwa rabala.
Makampani azaumoyo
Selenium ndi gawo lofunika kwambiri la ma enzyme ena oletsa antioxidant (glutathione peroxidase) ndi selenium-P protein mwa nyama ndi anthu, zomwe zimatha kupititsa patsogolo chitetezo cha mthupi cha anthu, khansa, matenda am'mimba, matenda a mtima ndi mitsempha yamagazi, matenda a prostate, matenda a maso, ndi zina zotero, kotero selenium imagwiritsidwa ntchito kwambiri m'zachipatala pochiza ndi kuchepetsa matenda osiyanasiyana omwe amayamba chifukwa cha kusowa kwa selenium. Popeza selenium ndi chinthu chofunikira kwambiri m'thupi la munthu ndipo chimakhudza kwambiri thanzi la munthu, makampani azaumoyo ayamba kupanga zinthu zosiyanasiyana zowonjezera selenium, monga selenium ya malt.
Mapulogalamu ena
Mu ulimi, selenium ikhoza kuwonjezeredwa ku feteleza kuti iwonjezere kusowa kwa selenium m'nthaka ndikulimbikitsa kukula kwa zomera. Selenium imagwiritsidwanso ntchito mu zodzoladzola, ndipo zodzoladzola zina zokhala ndi selenium zimakhala ndi zotsatira zotsutsana ndi ukalamba. Kuphatikiza apo, kuwonjezera selenium mu yankho la plating kungathandize kukonza mawonekedwe a zigawo za plating, kotero ndi chinthu chothandiza kwambiri.imagwiritsidwa ntchito ku makampani opanga ma plating.
