Rare magasi

Rare magasi, anozivikanwawo seakanaka magasi uye anokudzwa magasi, iboka rezvinhu zvinowanikwa mukudzika kwakadzika mumhepo uye zvakagadzikana zvakanyanya.Rare magasi ari muBoka Zero yePeriodic Tafura uye anosanganisira helium (Iye), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), iyo ichangobva kuwedzerwa iyo Periodic Table mhuri yezvinhu.
Magasi asingawanzo anotora 0.94% yemukati wemhepo, mazhinji ayo ari argon, uye haana ruvara, anonhuhwirira, asina kunaka, anonyungudika zvishoma mumvura, muchimiro chemonatomic gasi mamorekuru aripo mumhepo, ayo helium, neon, argon. , krypton, nokuti hapana radioactivity uye yakaoma zvikuru kuita pakupisa kwekamuri uye kumanikidzwa, inogona kushandiswa segasi rinodzivirira mu metallurgy, semiconductors nedzimwe minda.
Kunze kwegermanium, iyo inogona kuwanikwa chete yekugadzira, ine radioactive uye haina kugadzikana zvakanyanya, mamwe asingawanzo gasi zvinhu zvakaratidza kushandiswa kwakasiyana munzvimbo dzakasiyana kunze kwemagasi ekudzivirira.Huremu hweatomu hunongokwira kupfuura hydrogen, hunhu hweiyo helium yakagadzikana inogona kutsiva hydrogen sebharumu inozadza gasi, asi zvakare inogona kutsiva nitrogen seyakadzika dive neyakamanikidzwa gasi silinda yekuzadza gasi, kuitira kudzivirira kudhakwa nitrogen reaction uye oxygen. toxicity;argon ne-high-energy cosmic mwaranzi ichave ionized mushure mekuvhenekera, inogona kugadzikwa mumasatelliti ekugadzira ane argon counters kuti aone nzvimbo yemabhandi emwaranzi yepasi uye kusimba kwenzvimbo yepasi;xenon inogona kunyungudika mumaserura lipids, zvichikonzera cellular anesthesia.Xenon inogona kunyungudika mumafuta emaseru, kukonzera kuoma mitezo uye kuzvimba kwemaseru, uye kuita kuti masero etsinga amire kushanda kwenguva pfupi.Inogona kusanganiswa neokisijeni pachiyero che4: 1 seanesthetic gas pasina migumisiro;radon, seyo yega gasi reradioactive muzvisikwa, inogona kupesvedzerwa nekuora kwethorium muhurombo-mhando yekuvakisa, uye kukonzeresa cancer, asi inogona kusanganiswa nekunamwa neberyllium poda uye inoshandiswa senyuturoni sosi mumarabhoritari.
Magasi asingawanzo buditsa chiedza chakajeka uye chine simba kana chawedzerwa simba.Nekuzadza marambi nemusanganiswa wemhando dzakasiyana uye zviyero zve helium, neon, argon, krypton, mercury vapor, uye halogen makomponi, marudzi akasiyana ezviedza zvemwenje senge neon, fluorescent, fluorescent, uye mwenje wemotokari unogona kuwanikwa mune dzakasiyana siyana. mavara.
Nzvimbo yekunyunguduka uye kuvira kwemagasi asingawanzo kuderera, uye nzira yechinyakare ndeyekunyorovesa mhepo kuburikidza nemagetsi-inopedza kudzvanywa uye kutonhora uye wobva waipatsanura kuti uwane neon, argon, krypton uye xenon;helium inowanzobudiswa kubva gasi rechisikigo;uye radon inowanzoparadzaniswa kubva kune radium compounds mushure mekuora kweradioactive.
Shanghai Jiuzhou zeolite molecular sieve, isingawanzo gasi kupatsanura mhedzisiro yakanaka, kuchena kwakanyanya, kukurumidza kukurumidza, kuderera kwesimba rekushandisa, zvinoenderana neakasiyana mamiriro ekushanda kuti akupe iwe nehunyanzvi hwakagadziridzwa sevhisi.Tinotarisira kushanda nemi kuti tigadzire ramangwana riri nani.
