Argon gas yog siv nyob rau hauv fluorescent thiab incandescent qhov muag teev kom tsis txhob muaj oxygen nyob rau hauv lub qhov muag teev los ntawm corroding lub kub tungsten filament. Kev siv ntawm argon hauv qhov muag teev tiv thaiv cov evaporation ntawm tungsten filaments, uas ua rau muaj zog lub teeb lub neej.

Nyob rau hauv txoj kev no, yog vim li cas noble gases siv nyob rau hauv hluav taws xob qhov muag teev?

Helium , neon, argon thiab krypton yog siv hauv gas Tshem tawm cov teeb pom kev zoo nkauj, hu ua "neon" teeb . Argon yog siv kom puv incandescent qhov muag teev inhibit qhov evaporation ntawm tungsten filaments thiab nce noob lub neej. Qhov ntom ntawm cov cov pa roj nce nrog nce molecular mass.

Ib yam li ntawd, dab tsi yog siv los ua lwm txoj hauv kev rau argon hauv qhov muag teev? Nitrogen yog siv -chemically inactive thaum muaj nyob rau hauv nws lub xeev diatomic (N2). Cov no yog siv los tiv thaiv oxidation ntawm filament nyob rau hauv lub noob.

Tsis tas li ntawd, yog vim li cas argon roj siv nyob rau hauv lub teeb tab sis tsis yog cua?

Lub kaw iav chamber ntawm lub noob muaj, inactive (inert) gas , Argon . Lub iav chamber tsis tuaj yeem sau nrog huab cua Raws li lub xub ntiag ntawm oxygen yuav ua rau cov filament hlawv, i.e. react nrog oxygen. Ib qho obviously, inert gas yuav tsis hnov mob nrog filament. Nitrogen kuj yog siv nyiam argon.

Dab tsi yog kev siv argon?

Argon yog siv nyob rau hauv qee hom arc vuam xws li roj hlau arc vuam thiab roj tungsten arc vuam, nrog rau hauv kev ua cov titanium thiab lwm yam reactive hais. Ib argon Cov huab cua kuj tseem siv rau kev loj hlob muaju ntawm silicon thiab germanium.
