Cov compound no kuj tau siv dav hauv kev lag luam tu cov neeg ua haujlwm, cov khoom siv yas, thiab cov khoom siv tshuaj lom neeg vim nws cov kuab tshuaj muaj zog thiab ua tau zoo nrog cov tshuab loj - teev ntau lawm.
Rau cov ncauj lus kom ntxaws daim ntawv thov ntawm glacial acetic acid, thov nyem qhov no.
Yuav ua li cas tuav Acetic Acid kom zoo
Acetic acid yuav tsum tau ua nrog cov cuab yeej tiv thaiv kom zoo, qhov cua, thiab cov txheej txheem khaws cia vim tias cov tshuaj muaj zog tuaj yeem ua rau kub hnyiab, ua pa ua pa, thiab muaj tshuaj lom neeg hnyav.
Hnav cov tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab cov khaub ncaws tiv thaiv thaum tuav cov acetic acid. Hauv qhov chaw tsis muaj cua tsis zoo, siv lub tshuab ua pa pom zoo kom txo tau cov pa muaj zog.
Ib txwm ua haujlwm hauv qhov zoo- qhov chaw cua lossis hauv qab lub hood, tshwj xeeb tshaj yog thaum siv glacial acetic acid. Cov vapors tuaj yeem tsim sai sai hauv qhov chaw ib puag ncig thiab tuaj yeem ua rau lub qhov muag thiab ua pa.
Khaws acetic acid nyob rau hauv cov thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav kom deb ntawm tshav kub, nplaim taws, oxidizers, thiab alkaline tshuaj. Cov chaw muaj kev lag luam feem ntau siv corrosion-cov khoom siv tiv thaiv kom ruaj ntseg.
Yog tias muaj dej nchuav tshwm sim, cais thaj chaw, txhim kho qhov cua, thiab siv cov khoom siv tshuaj corrosive los ntxuav. Nyob rau hauv rooj plaub ntawm daim tawv nqaij lossis qhov muag, yaug tam sim nrog dej tsawg kawg 15 feeb thiab nrhiav kev kho mob yog tias tsim nyog.
