Cov kua qaub sulfamic siv rau dab tsi

Sulfamic acid, tseem hu ua aminosulfate, tau nce siab ua tus neeg sawv cev ntxuav ntau yam thiab siv tau ntau yam hauv ntau yam lag luam, vim nws cov qauv dawb crystalline ruaj khov thiab cov yam ntxwv zoo kawg. Txawm siv rau hauv tsev neeg lossis kev siv hauv kev lag luam, sulfamic acid tau txais kev qhuas dav dav rau nws cov peev xwm tshem tawm cov av thiab cov yam ntxwv kev nyab xeeb.

Ua haujlwm ua tus ntxuav kua qaub, sulfamic acid siv nws qhov tsis-hygroscopic thiab ruaj khov los muab cov txiaj ntsig ntxuav ntev thiab ua haujlwm tau zoo thoob plaws ntau yam xwm txheej. Qhov tseem ceeb, nws txo qis corrosiveness rau cov hlau piv rau cov kua qaub muaj zog xws li hydrochloric acid tso nws ua qhov kev xaiv zoo tshaj plaws rau kev tshem tawm cov nplai ntawm cov khoom siv hauv kev lag luam. Txij li cov khoom sib xyaw ua ke ntawm cov tsev txias mus rau cov qauv ruaj khov ntawm boilers, coils, thiab condensers, sulfamic acid zoo daws cov nplai thiab cov minerals, yog li ua rau cov khoom siv ua haujlwm zoo dua thiab kev tsim khoom tag nrho.

Ntxiv rau nws lub luag haujlwm tseem ceeb hauv kev tshem tawm cov av nplaum, sulfamic acid muaj ntau yam kev siv ntxiv, qhia txog nws qhov kev ua tau zoo thiab kev siv tau thoob plaws ntau yam lag luam. Ua tus catalyst hauv cov txheej txheem esterification, sulfamic acid pab txhawb kev tsim cov tshuaj tseem ceeb, pab txhawb rau kev tsim cov xim thiab cov xim uas ua rau peb ib puag ncig nplua nuj nrog cov xim ci ntsa iab. Ntxiv mus, nws muaj nyob rau hauv cov tshuaj tua kab thiab cov ntsiav tshuaj hniav cuav qhia txog nws qhov kev siv ntau yam thiab qhov tseem ceeb hauv cov khoom siv txhua hnub.

Hauv kev siv hauv tsev, cov kua qaub sulfamic maj mam hloov cov kua qaub hydrochloric ua cov tshuaj zoo tshaj plaws rau kev ntxuav thiab tshem cov av nplaum. Nws cov tshuaj lom tsawg, tsis tshua muaj kev hloov pauv, thiab muaj peev xwm tshem cov av nplaum zoo heev ua rau feem ntau ntawm cov neeg siv nrhiav kev ntxuav kom huv thiab muaj txiaj ntsig zoo rau kev saib xyuas hauv tsev.

Qhov ua tau ntau yam ntawm sulfamic acid nthuav dav mus rau hauv cov chaw lag luam, qhov twg nws cov txiaj ntsig tau siv thoob plaws ntau qhov chaw los daws cov teeb meem tshwj xeeb thiab txhim kho cov txheej txheem ua haujlwm. Hauv kev lag luam ntawv thiab pulp, sulfamic acid ua haujlwm ua lub hauv paus tseem ceeb ntawm kev puas tsuaj ntawm pulp, tiv thaiv daim ntawv lub zog thaum lub sijhawm ua kom dawb kub. Ib yam li ntawd, hauv kev lag luam zas xim thiab pigment, sulfamic acid pab tshem tawm cov nitrogen ntau dhau uas siv rau hauv cov tshuaj diazotization, ua kom ntseeg tau tias cov khoom zoo tshaj plaws thiab cov txheej txheem ua haujlwm tau zoo.

Hauv kev xaus lus, sulfamic acid tsis yog tsuas yog ib yam khoom siv ntxuav xwb tab sis nws yog ib qho kev daws teeb meem tseem ceeb uas tsav kev ua tau zoo thiab kev ruaj khov thoob plaws ntau yam lag luam. Nws lub peev xwm tshem tawm cov av nplaum, ua ke nrog nws cov ntawv thov dav dav, tso nws ua lub hauv paus rau kev txhim kho yav tom ntej hauv cov thev naus laus zis ntxuav thiab cov txheej txheem kev lag luam. Thaum cov lag luam muab qhov tseem ceeb rau kev nyab xeeb, kev ua haujlwm zoo, thiab kev paub txog ib puag ncig, sulfamic acid tau npaj siab los ua lub luag haujlwm nthuav dav, txhawb nqa ib puag ncig huv si, muaj kev nyab xeeb dua thiab pab txhawb kev ua haujlwm zoo thoob plaws ntau qhov chaw. Vim muaj cov yam no, kev xav txog thiab kev siv sulfamic acid hauv ntau yam kev siv yog qhov tseem ceeb rau kev qhib nws lub peev xwm tag nrho thaum ua kom muaj kev coj ua ruaj khov thiab muaj lub luag haujlwm hauv kev lag luam.
