Dab tsi yog sulfamic acid siv rau?
Sulfamic acid (h₃₃ss₃), tseem hu ua amidosulfonic acid, yog lub soluble dej, dawb crystalline compound nrog ntau yam kev lag luam, lag luam, thiab kev thov hauv tsev, thiab tsev neeg. Nws cov tshuaj tshwj xeeb-suav nrog muaj zog acidity, qis tsis khov, thiab tsis yog-corrosive xwm mus rautej hlau-Thov nws muaj ntau yam sib txuas hauv cov teb muaj ntau lub teb. Tsab ntawv no tshawb nrhiav tus thawj siv ntawm sulfamic acid, relving mus rau hauv nws lub luag haujlwm hauv kev lag luam tu, kev kho dej, thiab dhau ntawd. Kuaj cov tshuaj, thiab dhau.
1. Kev lag luam thiab tsev neeg tu
Ib qho ntawm cov ntawv tshaj tawm tseem ceeb tshaj plaws ntawm sulfamic acid yog li atus neeg saib xyuas tus neeg sawv cevHauv cov khoom lag luam thiab tsev neeg tu. Nplai, feem ntau tsim ntawm calcium carbonate (caco₃), magnesium kub, thiab tsev neeg cov cuab yeej siv thiab kettles. Sulfamic acid reacts nrog cov nyiaj no los tsim cov dej-soluble complex, zoo tsis muaj qhov lawv tsis muaj qhov chaw hlau ua haujlwm. Nws cov tshuaj tiv thaiv nrog calcium carbonate tuaj yeem sawv cev raws li:
Caco₃ {+ 2 h₃sso₃ → CA (h₂sso₃) ₂ + + + h₂o
Piv nrog hydrochloric acid los yog citric acid, sulfamic acid muaj zoo:
Tsis yog-corrosive rau cov hlau: Muaj kev nyab xeeb rau kev siv ntawm hlau, tooj liab, thiab tooj dag.
Tsawg ntxhiab thiab pa taws: Haum rau sab hauv tsev.
Ib qho yooj yim tuav: Muag raws li cov hmoov uas ruaj khov los yog ua ntej-diluted daws.
Kev lag luam xws li lub zog ua haujlwm, kev ua zaub mov, thiab tsim kev tso nyiaj vim yog kev ua haujlwm zoo thiab tiv thaiv kom lub zog txhim kho.
2. Dej kho thiab ua luam dej pas
Hauv cov dej kho tshuab, sulfamic acid ua haujlwm rau ob lub hom phiaj:
PHOONATION: Nws txo qis pH of alkaline dej, tiv thaiv corrosion thiab kev tso nyiaj hauv av thiab pob zeb hauv qab.
Chlorine Ruaj Khov: Nws reacts nrog cov chlorine tshaj (CLT) los uaN-chlorosulfamulfamic acid, Qhov sib xyaw uas maj mam tso cov tshuaj chlorine dhau sijhawm. Cov cuab yeej no tau siv cov pas dej da dej thiab cov ntoo lim dej kho kom muaj cov tshuaj tua kab mob sib xws.
Ib qho ntxiv, cov sulfamic acid yog siv los tshem tawm biofilm-ib txheej ntawm cov kab mob ntawm cov kab mob thiab cov organic teeb meem-los ntawm cov tshuab faib khoom. Nws cov khoom biocidal pab txo cov kev loj hlob microbial tsis tas yuav tawm musTshuaj lom zem.
3. Kuaj thiab ntsuas aneverical
Nyob rau hauv lub chaw soj nstuam, sulfamic acid yog muaj nuj nqis rau nws lub luag haujlwm ua athawj tus qauvHauv acid-base scrations. Nws cov kev huv siab, ruaj khov, thiab meej molecular hnyav (97.09 g \/ mol) ua rau nws zoo li sodium hydroxide (Naoh).
Nws tseem ua raws li aNitrite ScavengerHauv kev siv tshuaj lom neeg. Piv txwv li, hauv cov txheej txheem diazotization (siv los txhawb cov khoom noj thiab kws tshuaj), ntau tshaj nitrous acid (hnoo₂) yuav tsum tsis txhob mob sab nraud. Sulfamic acid nrawm decomposes nitrites:
Hnoo₂ + h₃sso₃ → + h ₂so₄ + h₂o
Cov tshuaj tiv thaiv no ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov txheej txheem sib koom ua hluav taws xob.
4. Khoom cua ntawm cov kws tshuaj thiab agnochnicals
Sulfamic acid yog qhov tseem ceeb hauv nruab nrab hauv kev tsim covsulfonamide tshuaj, Chav kawm ntawm cov tshuaj tua kab mob uas cuam tshuam los ntawm kev cuam tshuam cov kab mob los ntawm kev cuam tshuam nrog kev sib cuam tshuam cov tshuaj synthesis. Piv txwv li sulpadiazine thiab sulfamethoxole. Nws amino (-nh₂) thiab sulfonic (-so₃h) pab pawg ua rau kev tsim cov ruaj khov, molicactive molecules.
Nyob rau hauv agnochemicals, sulfamic acid derivatives yog siv los tsim cov tshuaj ntsuab thiab fungicides. Piv txwv li,ammonium sulfamate(Sulfamic Acid Ntsev Ntsev) yog thov raws li tus neeg tua neeg uas tsis xaiv Willer ntawm kev tsheb ciav hlau thiab cov chaw muaj kev lag luam vim nws cov hauj lwm zoo tiv thaiv cov nroj tsuag tob.
5. Khoom noj khoom haus thiab dej haus
Txawm hais tias sulfamic acid tsis yog zaub mov ntxiv, nws plays lub luag haujlwm tseem ceeb hauvCov Khoom Siv Ua Khoom Siv Ua SiCov. Cov khoom siv ua haujlwm tsis zoo, cov nroj tsuag tso dej, thiab tso cov misstone, mis nyuj, cov pasturizers, thiab cov raj dej. Nws cov txiaj ntsig suav nrog:
Tsis muaj kev phom sij uas tuaj yeem paugkhoom.
Compatibility nrog cov hlau stainless thiab roj hmab ntsaws ruaj ruaj.
Nyob rau hauv qab zib refining, sulfamic acid tiv thaiv carmamelization thaum lub sij hawm tswj kav pH cov qib, ua kom muaj txiaj ntsig ntau dua ntawm cov suab thaj.
6. Textile thiab Cov Ntawv Lag Luam
Textile Manufacturersers siv cov sulfamic acid rau:
Tshuaj dawb: Nws tshem tawm impurities los ntawm ntuj fibers zoo li paj rwb thiab ntaub plaub.
Zas kho: Nws nws txhim kho txoj kev tuag ntawm cov ntaub, txhim kho xim xim.
Hauv ntawv ntau lawm, sulfamic acid hloov kho pulp pyc thaum noj mov nrog hydrogen peroxide (h₂o₂), ua kom zoo dua qhov ci thiab lub zog ntawm cov ntawv khoom.
7. Hlau ua thiab Electroplating
Sulfamic acid yog ib feem ntawmCov Hluav Taws Xob Cov Chav DejRau cov hlau xws li tin, txhuas, thiab zinc. Nws ntseeg tau du, txawm txov los ntawm kev tiv thaiv kev tsim cov tshuaj ntsuab ntawm cov hlau. Ib qho ntxiv, nws tau siv rau Polish Silverware thiab cov hniav nyiaj hniav kub, tshem cov hannish tsis muaj khawb cov khoom zoo nkauj.
8. Kev nyab xeeb thiab tuav
Thaum sulfamic acid feem ntau muaj kev nyab xeeb dua li ntxhia acids, kev ceev faj yog tsim nyog:
Lom zem: Nws yog mentkately lom yog noj lossis nqus tau.
Tawv \/ Qhov Muag Hnov: Siv hnab looj tes thiab hnab looj tes thaum tuav cov kev daws teeb meem.
Chaw ntim khoom: Khaws rau hauv qhov chaw txias, qhuav kom deb ntawm alkalis thiab oxidizing cov neeg sawv cev.
Cov koom haum tswj hwm zoo li EPA thiab OSHA cais sulfamic acid li kev pheej hmoo tshuaj lom neeg thaum siv raws li qhia.
Tag
Los ntawm tsis muaj cov roj cua kom muaj cov tshuaj txuag lub neej, sulfamic acid cov lus ntawm nws cov chemicals. Raws li kev lag luam nrhiav muaj kev nyab xeeb dua, cov kev xaiv ntsuab ntxiv rau cov tshuaj hnyav, cov kua qaub sulfas acid txuas ntxiv. Kev Tshawb Fawb Cov Tshiab Siv Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob, nplaim taws Retardants, thiab txawm tias cov thev naus laus zis kev sib cav, ua kom tau raws li lub neej tom ntej.
