iav fwj cov khoom yuav tsum tau them sai sai rau lawv cov tshuaj stability

Cov iav fwj cov khoom yuav tsum tau eroded los ntawm dej, kua qaub, alkali, ntsev, roj, thiab lwm yam tshuaj reagent daws thaum siv, thiab cov kuj ntawm iav rau cov yaig no yog hu ua tshuaj stability. Cov tshuaj ruaj khov ntawm cov khoom siv iav iav feem ntau yog tshwm sim hauv kev yaig ntawm cov dej rau iav thiab kev yaig ntawm cov cua ntawm lub khob.

Hauv kev tsim cov khoom siv iav hauv tsev, qee lub chaw tsim khoom me me qee zaum xav tias txhawm rau txo qhov kub ntawm cov iav, nws ntseeg tau tias NA.₂O cov ntsiab lus hauv kev tsim cov iav chemistry lossis txo cov SiO₂cov ntsiab lus los txo cov tshuaj stability kev ua tau zoo ntawm cov iav. Cov khoom siv iav lub raj mis uas tsis muaj tshuaj lom neeg ruaj khov tau khaws cia rau lub sijhawm ntev hauv qhov chaw ntub dej, ua rau cov plaub hau plaub hau ntawm cov khoom lag luam thiab poob qhov ci thiab pob tshab ntawm iav nws tus kheej. Lub stabilization ntawm iav anti-hydraulic chemistry txo qis.

Qhov no yuav tsum nyiam txaus mloog. Tsis txhob ua ntau dhau kom txo qis qhov kub thiab ua kom NA₂O cov ntsiab lus. Qee cov neeg ua haujlwm feldling yuav tsum tau qhia kom tsim nyog, los yog tshuaj muaj pes tsawg leeg kom txo tau lub melting kub, txwv tsis pub nws yuav coj teeb meem loj rau cov khoom. Qee lub sij hawm vim tias tsis muaj tshuaj lom neeg ruaj khov, zoo li "rov qab alkali" thaum lub sijhawm ntawd, tab sis tom qab xa tawm mus rau qee lub tebchaws uas muaj huab cua loj, "alkali rov qab" yuav ua rau poob nyiaj ntau dua. Yog li ntawd, hauv kev tsim cov iav ntau lawm, cov tshuaj ruaj khov ntawm cov iav yuav tsum txaus.
