CAS No. 7446-9-5 Sulfur Dioxide Manufacturers. Daim ntawv teev npe ntawm Sulfur Dioxide
Sulfur dioxide (SO₂) yog cov pa tshuaj lom nrog cov ntxhiab tsw ntxhiab tsw. Nws yog ib qho byproduct ntawm ntau yam kev lag luam txheej txheem thiab kuj yog tsim los ntawm volcanic kev ua si. Nov yog qee cov yam ntxwv tseem ceeb ntawm sulfur dioxide:
Chemical Properties:
Molecular Formula: SO₂
Molecular Luj: Kwv yees li 64.06 g / mol
CAS Nr .: 7446-09-5
Lub cev muaj zog:
Nyob rau hauv chav tsev kub thiab siab, nws zoo nkaus li tsis muaj xim tsis muaj roj.
Nws hnyav dua li huab cua, nrog qhov ceev ntawm li 2.9 kg / m³ ntawm cov qauv txheej txheem.
Sulfur dioxide muaj qhov kub ntawm -10.0 ° C (14 ° F) thiab melting point -72.7 ° C (-98.9 ° F).
Toxicity:
Sulfur dioxide yog ua pa ua pa thiab tuaj yeem ua rau muaj teeb meem kev noj qab haus huv loj thaum nqus tau.
Cov concentration ntau tuaj yeem ua rau mob ntsws loj, mob ntsws, lossis tuag taus.
Nws kuj tuaj yeem ua rau lub qhov muag thiab cov mucous.
Environmental Impact:
Nws ua rau acid nag tsim thaum nws hnov mob nrog dej vapor hauv qhov chaw.
Sulfur dioxide kuj tseem tuaj yeem ua rau tsim cov khoom me me uas tuaj yeem cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv thiab kev pom.
Kev siv:
Hauv kev lag luam khoom noj khoom haus, sulfur dioxide yog siv los ua tshuaj tiv thaiv oxidation thiab microbial kev loj hlob.
Nws yog siv nyob rau hauv zus tau tej cov sulfuric acid.
Nws plays lub luag hauj lwm nyob rau hauv lub pulp thiab ntawv kev lag luam rau bleaching ntoo pulp.
Sulfur dioxide kuj tseem siv rau hauv cov txheej txheem cawv los tiv thaiv kev lwj.
Hais txog cov chaw muag khoom, cov neeg muag tshuaj loj feem ntau nqa cov sulfur dioxide, thiab nws yuav muaj ntau yam xws li compressed gas cylinders lossis cov thawv ntim kua.Rau kev nyab xeeb thiab tuav cov ntaub ntawv, nco ntsoov xa mus rau Cov Ntaub Ntawv Kev Nyab Xeeb Cov Ntaub Ntawv (MSDS) lossis Daim Ntawv Qhia Kev Nyab Xeeb ( SDS) muab los ntawm tus neeg muag khoom. Cov txheej txheem khaws cia thiab tuav kom raug yog qhov tseem ceeb vim nws qhov xwm txheej txaus ntshai. Yog tias koj xav tau cov ntaub ntawv ntxaws ntxaws lossis ib tus neeg muag khoom tshwj xeeb cov ntaub ntawv tiv tauj, kuv yuav tsum paub koj qhov chaw nyob thiab qhov ntsuas ntawm koj qhov yuav tsum tau ua. Thov qhia rau kuv paub yog tias koj xav tau kev pab ntxiv.
