4. Decolorizing Cov Khoom:

- Nws siv nyob rau hauv lub khob thiab ceramics kev lag luam pab tsim cov khoom lag luam zoo, visually thov kom zoo.

1. Toxicity:

- Selenium dioxide 丨 {{7446-08-4 yog cov tshuaj lom tau heev yog noj, nqus tau ntawm daim tawv nqaij. Nws tuaj yeem ua pa hnyav, txoj hnyuv liab, thiab cov teebmeem neurological. Cov khoom siv tiv thaiv tus kheej kom tsim nyog (PPE), xws li hnab looj tes, goggles, thiab nqus pa, yuav tsum tau siv thaum tuav cov compress no.

2. Ib puag ncig cuam tshuam:

- Selenium cov tebchaw yuav ua rau muaj kev phom sij rau cov neeg muaj lub neej thiab ib puag ncig. Cov hau kev tsim nyog uas tsim nyog yuav tsum tau ua kom tsis txhob muaj kev paug.

3. Kev tswj hwm ua raws li:

- Kev siv thiab tuav ntawm Selenium Dioxide yog raug rau txoj cai nruj vim nws cov kuab lom. Ua raws li cov lus qhia kev nyab xeeb thiab cov cai hauv zos yog qhov tseem ceeb.

4. Cia thiab tuav:

- Selenium dioxide yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, kom deb ntawm cov ntaub ntawv tsis sib xws xws li txo cov neeg sawv cev thiab cov organic sib txuas. Nws yuav tsum tau daws nyob rau hauv ib qho kev ua cua zoo-ventilated hood kom txo qis kev raug.

Selenium dioxide 丨 {{7446-08-4 yog cov khoom siv muaj txiaj ntsig zoo nrog cov ntawv thov hauv cov khoom siv hauv Suav teb, iav tsim khoom, electroplating, thiab ntau dua. Nws xaiv oxidizing cov zog thiab versatility ua rau nws tsis tseem ceeb hauv ntau yam kev lag luam. Txawm li cas los xij, nws txoj kev lom zem thiab ib puag ncig cuam tshuam ua kom muaj kev tiv thaiv kev nyab xeeb nruj thiab muaj lub luag haujlwm tuav. Los ntawm adhering rau kev nyab xeeb cov cai thiab cov kev pab cuam tshuam, cov txiaj ntsig ntawm selenium dioxide tuaj yeem siv cov kev pheej hmoo rau kev noj qab haus huv thiab ib puag ncig.
