Nws yog feem ntau pom hauv cov tais dej ntxuav thiab chav ntxuav chav dej vim nws lub peev xwm tshem tawm cov stains nyuaj, xeb, thiab cov dej tsis muaj xeb. Nws kuj yog siv nyob rau hauv kev tu cov kev ntxuav sib xyaw rau kev tshem cov txheej oxide thiab corrosion.
Ph Haum:Cov roj sulfamic feem ntau siv los kho cov ph theem hauv ntau yam kev siv. Nws ua raws li tus neeg sawv cev pH ua haujlwm hauv pas dej ua luam dej, cov dej kho, thiab cov txheej txheem tshuaj lom neeg, thiab siv tshuaj lom neeg ua haujlwm.
Hluav Taws Xob: Cov kua roj sulfamic yog siv rau hauv cov hluav taws xob da dej da dej me thiab ruaj khov. Nws ua kom pom tseeb cov nplaum kom raug thiab txhim kho kom zoo ntawm cov hlau plating ntawm ntau substrates.
Dyeing thiab tshuaj dawb tus neeg sawv cev: Cov kua qaub sulfamic yog siv rau hauv textile thiab cov ntawv lag luam ua dyeing thiab tshuaj dawb. Nws pab tshem tawm cov xim tsis xav tau lossis cov nplaum los ntawm cov ntaub thiab cov ntawv.
Tshuaj ntsuab:Sulfamic acid yog siv nyob rau hauv cov synthesis ntawm cov tshuaj tua kab thiab cog cov neeg tswj hwm kev loj hlob. Nws ua raws li kev sib cav tseem ceeb hauv kev tsim cov qauv xaiv thiab tsis xaiv tshuaj ntsuab.
Kws Tshuaj thiab Tshuaj Synthesis:Sulfamic acid ua haujlwm ua cov khoom siv pib lossis catalyst hauv kev tsim cov tshuaj, tshuaj lom neeg, thiab nruab nrab. Nws koom nrog kev tawm tsam zoo li Esterification, Kev cog lus, thiab sulfation.
Nws yog ib qho tseem ceeb kom nco ntsoov tias thaum siv sulfamic acid, ua kev ceeb toom rau kev tiv thaiv zoo li, suav nrog kev ua pa tawm tsam, thiab tuav nws raws li kev nyab xeeb thiab cov cai.
