Txawm hais tias magnesium oxide tseem tuaj yeem siv tau tom qab nws tau deteriorated nyob ntawm qhov℃ntawm deterioration thiab nws npaj siv. Cov magnesium oxide me me tuaj yeem kho tau thiab rov siv dua ntawm qib qis, thaum tsis zoo magnesium oxide tsis pom zoo siv.
1. Kev Txiav Txim Siab Tsis Zoo
Kev hloov tshuaj lom neeg: Cov magnesium oxide deteriorated tau reacted nrog dej los yog CO₂ los ua magnesium hydroxide los yog magnesium carbonate, thiab cov ntsiab lus ntawm active MgO tau txo qis.
Lub cev tshwm sim: Clumping, hardening, thiab darkening ntawm cov xim tshwm sim, thiab fluidity ploj.
Cov ntsuas ntsuas: Active magnesium oxide cov ntsiab lus<60% (refer to HG/T 3928-2012), moisture >1.5%, suav tias yog deteriorated.
Me ntsis Deterioration: me ntsis deg hydration, nrog qee qhov kev ua haujlwm sab hauv seem;
Kev puas tsuaj loj: Tag nrho cov oxide txheej yog tawv zoo li pob zeb, thiab nws cov khoom siv tshuaj muaj kev hloov pauv tsis tau.
2. Cov lus pom zoo rau qhov sib txawv ntawm qhov ua tsis tiav

Kev Ua Phem Loj |
Tsis pom zoo |
Kev poob haujlwm hnyav; Kev siv yuam kev tuaj yeem ua rau cov khoom tawg thiab kev ua haujlwm tsis ruaj khov. |
Rau siab - daim ntawv thov precision (xws li hluav taws xob ceramics, tshuaj excipients), txhua theem ntawm kev ua tsis tiav yog qhov tsis lees txais.
3. Txoj kev rov ua dua tshiab thiab rov siv dua
Kev Siv Khoom Siv: tuaj yeem siv los ua cov av txias hauv kev ua liaj ua teb kom tsis txhob muaj cov av acidic.
Environmental Applications: Siv los ua cov pa roj desulfurizer lossis pH adjuster hauv kev kho dej khib nyiab.
Kev Siv Khoom Siv Hauv Tsev: Ntxiv ib qho me me rau qis -qib pob zeb lossis blocks kom txo tau cov nqi.
Txhua txoj hauv kev rov siv dua yuav tsum muaj qhov ntsuas me me - kom paub meej tias qhov kev ua tau zoo ntawm cov khoom kawg tsis cuam tshuam.
