Sulfamic acid, raws li ib tug muaj zog organic acid, tau lug siv nyob rau hauv lub teb ntawm industrial tu vim nws zoo detergency, tsis muaj corrosiveness rau hlau thiab ib puag ncig tiv thaiv. Cov kav dej yog ib feem tseem ceeb ntawm kev lag luam niaj hnub no thiab lub neej. Nws tu thiab tu yuav cuam tshuam ncaj qha rau kev tsim khoom. Kab lus no yuav tham txog qhov zoo ntawm daim ntawv thov thiab kev ceev faj ntawmSulfamic acid hauv kev ntxuav cov kav dej.
Sulfamic Acid yog dab tsi?
Sulfamic acid yog cov xim tsis muaj xim los yog dawb particle nrog zoo solubility thiab stability. Nws yog ib qho khoom siv tshuaj lom neeg uas muaj cov amino pawg (-NH2) thiab sulfonic acid pawg (-SO3H). Nws feem ntau yog siv los ua dej kho, tshuaj ntxuav thiab tshuaj reagent. Raws li cov khoom siv acidic, sulfamic acid tuaj yeem yaj cov hlau oxides, calcium nplai, xeb thiab nplai, yog li nws muaj qhov zoo hauv kev tu cov kav dej.
Cov yam ntxwv thiab qhov zoo ntawm Sulfamic Acid
Yog vim li cas vim li cas sulfamic acid tuaj yeem dhau los ua tus neeg saib xyuas cov yeeb nkab zoo yog sib cais los ntawm nws cov khoom tshwj xeeb.
Muaj zog acidity: Sulfamic acidmuaj zog acidity thiab muaj peev xwm yaj ntau yam inorganic ntsev, oxides thiab organic teeb meem txuas rau sab hauv phab ntsa ntawm cov kav dej. Nws yog qhov zoo tshwj xeeb ntawm kev ua kom cov calcium thiab magnesium ntsev sediments, thiab yog qhov zoo rau kev tsim cov phab ntsa sab hauv ntawm cov kav dej. Nws muaj kev tu kom pom tseeb ntawm cov teeb meem nplai. Piv nrog rau cov tshuaj ntxuav cov tshuaj ib txwm siv, xws li hydrochloric acid, sulfamic acid tsis tsuas yog muaj kev ua haujlwm siab, tab sis kuj tsis tsim cov pa phem los yog cov khoom tsim kev puas tsuaj rau qee qhov, thiab tuaj yeem tiv thaiv cov kav dej thiab khoom siv zoo dua.
Tsawg corrosiveness:Piv nrog rau cov tshuaj inorganic muaj zog acids, sulfamic acid yog tsawg corrosive rau hlau kav (stainless steel, tooj liab kav, txhuas alloys, cam khwb cia hlau, thiab lwm yam). Nws muaj kev nyab xeeb dua thaum ntxuav cov kav dej ntawm ntau yam khoom siv. Qhov no ua rau nws tsim nyog tshwj xeeb rau kev lag luam nrog cov kev xav tau siab dua ntawm cov khoom siv kav dej, xws li kev ua zaub mov, tshuaj, hluav taws xob thiab lwm yam lag luam.
Siab solubility:Sulfamic acid thiab nws cov ntsev tuaj yeem tsim cov txheej txheem soluble nrog ntau yam hlau ions, uas ua rau nws muaj txiaj ntsig zoo hauv kev tshem tawm cov hlau oxides thiab nplai.
Yooj yim rau kev khiav lag luam thiab tswj:Thaum siv sulfamic acid rau kev ntxuav cov kav dej, nws feem ntau tsuas yog xav tau kev npaj yooj yim ntawm kev ntxuav thiab ntxuav raws li qee qhov kev xav tau thiab qhov kub thiab txias. Piv nrog rau cov txheej txheem kev tu neeg kho tshuab ib txwm muaj, kev tu tshuaj lom neeg yooj yim dua thiab txuag tau ntau tus neeg ua haujlwm thiab sijhawm. Cov txheej txheem siv sulfamic acid yog qhov yooj yim thiab tuaj yeem ua haujlwm ntawm qhov kub thiab txias, ua rau cov txheej txheem ntxuav cov kav dej kom ruaj khov thiab tswj tau.
Kev siv sulfamic acid hauv kev ntxuav cov kav dej
Sulfamic acid muaj ntau yam kev siv hauv kev tu cov kav dej, feem ntau suav nrog cov hauv qab no:
Boilers thiab cov khoom siv hluav taws xob sib pauv:Sulfamic acid tuaj yeem tshem tawm cov nplai thiab cov khoom siv corrosion hauv boilers, condensers, cov khoom siv hluav taws xob thiab lwm yam khoom siv, txhim kho cov thermal efficiency ntawm cov cuab yeej, thiab txuas ntxiv lub neej kev pab cuam ntawm cov cuab yeej.
Chemical pipelines:Thaum lub sij hawm tsim cov txheej txheem tshuaj, cov phab ntsa sab hauv ntawm cov kav dej yog qhov ua rau scaling thiab corrosion. Sulfamic acid tuaj yeem tshem tawm cov av no thiab ua kom cov kav dej du thiab ua haujlwm zoo ntawm cov khoom siv.
Khoom noj khoom haus kev lag luam:Cov khoom siv ua zaub mov muaj kev nyiam huv heev. Sulfamic acid tuaj yeem tshem tawm cov proteins, rog thiab lwm yam khoom siv hauv cov khoom siv los ua kom muaj kev nyab xeeb thiab kev nyiam huv ntawm cov khoom noj.
Papermaking khoom:Thaum lub sij hawm cov txheej txheem papermaking, ntoo pulp fibers, fillers thiab lwm yam khoom zoo li tsub kom nyob rau hauv lub puab phab ntsa ntawm lub raj. Sulfamic acid tuaj yeem tshem tawm cov av no thiab txhim kho cov tawv nqaij zoo.
Tej yam yuav tsum nco ntsoov thaum ntxuav cov kav dej sulfamic acid
Txawm hais tias sulfamic acid muaj ntau yam zoo hauv kev tu cov kav dej, cov ntsiab lus hauv qab no yuav tsum tau muab sau tseg rau hauv kev siv tswv yim:
Concentration tswj:Qhov concentration ntawm sulfamic acid yuav tsum tau xaiv kom tsim nyog raws li hom thiab qib ntawm cov av. Yog tias qhov concentration siab dhau lawm, nws yuav yooj yim corrode cov kav dej, thiab yog tias cov concentration tsawg dhau, cov nyhuv tu yuav tsis zoo.
Kev tswj qhov kub thiab txias:Kev ua kom kub ntawm cov dej ntxuav yuav pab ua kom cov tshuaj tiv thaiv sai, tab sis yog tias qhov kub thiab txias siab dhau lawm, cov pa phem yuav tsim tau yooj yim, yog li nws yuav tsum tau tswj nyob rau hauv qhov tsim nyog (feem ntau qis dua 60 ° C).
Kev tswj lub sijhawm: If lub sij hawm ntxuav yog luv dhau, cov av tsis tuaj yeem tshem tawm tag nrho; yog tias lub sijhawm tu ntev dhau lawm, nws yuav yooj yim ua rau tsis tsim nyog corrosion rau cov kav dej.
Kev tiv thaiv kev nyab xeeb:Sulfamic acid yog corrosive. Cov tsom iav tiv thaiv, hnab looj tes thiab lwm yam khoom siv tiv thaiv yuav tsum tau hnav thaum lub sijhawm ua haujlwm kom tsis txhob sib cuag nrog daim tawv nqaij.
Raws li tus neeg saib xyuas zoo thiab nyab xeeb, sulfamic acid plays lub luag haujlwm tseem ceeb hauv kev tsim khoom. Los ntawm kev xaiv cov concentration, kub thiab lub sijhawm, thiab siv cov kev tiv thaiv zoo sib xws, qhov zoo ntawm sulfamic acid tuaj yeem siv tag nrho, cov nyhuv ntawm cov kav xa dej tuaj yeem txhim kho, thiab kev pab cuam lub neej ntawm cov cuab yeej siv tau ntev.
