Sulfamic acid, yog muaj zog organic acid, tau muab dav siv nyob rau hauv lub tshav pob tu vim nws cov tshuaj ntxuav tau zoo heev, kev tiv thaiv kab mob qis thiab kev tiv thaiv ib puag ncig. Pipelines yog ib feem tseem ceeb ntawm kev lag luam niaj hnub no thiab lub neej. Nws tu thiab txij nkawm yuav cuam tshuam ncaj qha cuam tshuam rau ntau lawm. Kab lus no yuav tham txog daim ntawv thov zoo thiab ceev faj ntawmSulfamic acid nyob rau hauv pipeline tu.
Dab tsi yog sulfamic acid?
Sulfamic acid yog lub crystal tsis muaj xim lossis dawb particle nrog zoo solubility thiab ruaj khov. Nws yog ib qho tshuaj lom organic yog cov muaj kev sib xyaw ntawm cov amino pab pawg (-NH2) thiab sulfonic acid pawg (-so3h). Feem ntau nws siv tau ua dej tshuaj, tu tus neeg saib xyuas thiab tshuaj lom neeg. Raws li cov tshuaj acidic, sulfamic acid tau zoo tshem tawm cov hlau oxides, xeb nplai, yog li nws muaj qhov tseem ceeb hauv pipeline tu.
Cov yam ntxwv thiab cov txiaj ntsig ntawm sulfamic acid
Qhov laj thawj yog vim li cas sulfamic acid tuaj yeem ua cov yeeb nkab tu kom huv yog cov neeg sawv cev yog tsis muaj txiaj ntsig los ntawm nws cov khoom tshwj xeeb.
Muaj zog acidity: Sulfamic acidMuaj cov muaj kuab acidity thiab muaj peev xwm tshem tawm cov ntsev ntau yam ua ke, oxides thiab cov organic teeb tsa txuas nrog phab ntsa sab hauv ntawm cov raj xa dej. Nws yog qhov tshwj xeeb zoo ntawm dissolving calcium thiab magnesium ntsev sediments, thiab yog qhov zoo rau kev tsim ntawm phab ntsa sab hauv ntawm lub raj raj. Nws tau pom tseeb kev ua tiav ntawm cov teeb meem kev teeb meem. Piv nrog cov tsoos acidic ntxuav cov neeg sawv cev, xws li cov roj ntsha hydrochloric acid, tab sis tsis muaj kev phom sij hauv cov khoom siv, thiab tuaj yeem tiv thaiv cov raj xa khoom thiab khoom siv zoo dua.
Qis corrosived:Piv nrog cov tsoos inorganic muaj zog acids, sulfamic acids, sulfamic acid yog cov kav hlau (stainless hlau, tooj liab kav, aluminium alloys, cam khwb cia hlau, thiab lwm yam). Nws muaj kev nyab xeeb dua thaum tu cov kav dej ntawm ntau yam ntaub ntawv. Qhov no ua rau nws haum tshwj xeeb rau kev lag luam nrog cov khoom siv hluav taws xob siab dua ntawm cov khoom siv raj dej, xws li kev ua zaub mov, tshuaj, khoom siv hluav taws xob thiab lwm yam kev lag luam.
Siab solubility:Sulfamic acid thiab nws cov ntsev yuav ua rau soluble ua nrog ntau yam hlau ions, uas muab nws qhov tseem ceeb hauv kev tshem tawm cov hlau oxides thiab nplai.
Yooj yim rau kev khiav lag luam thiab tswj:Thaum siv sulfamic acid rau pipeline tu, nws feem ntau tsuas yog xav tau kev ntxuav cov kev ntxuav thiab tu raws li qee yam kev xav thiab txias. Piv nrog cov tsoos kho cov hau kev ntxuav, tshuaj ntxuav tshuaj yog yooj yim dua thiab txuag tau ntau lub manpower thiab sijhawm. Kev siv cov txheej txheem ntawm cov sulfamic acid kuj yooj yim thiab tuaj yeem ua haujlwm ntawm qis dua kub, ua kom cov raj xa dej ntxuav roj av ruaj khov thiab tswj tau.
Daim ntawv thov ntawm sulfamic acid hauv pipeline tu
Cov kua qaub sulfamic muaj ntau cov kev siv hauv kev tu pipeline ntxuav, feem ntau yog suav nrog cov hauv qab no:
Boilers Thiab Tshav Kub Excha Khoom:Cov kua qaub sulfamic tuaj yeem tshem tawm cov nplai thiab corrosion khoom sab hauv cov rwj, thiab lwm yam khoom siv cua sov, thiab txuas ntxiv cov kev pabcuam lub neej ntawm cov khoom siv.
Tshuaj Pip Cais Kav:Thaum lub sij hawm cov txheej txheem kev siv tshuaj Cov kua qaub sulfamic tuaj yeem tshem tawm cov av no thiab kom muaj cov raj xa khoom du thiab ua haujlwm ib txwm ua.
Kev lag luam khoom noj:Cov khoom noj khoom noj muaj cov kev xav tau ntawm cov kev xav tau. Cov kua qaub sulfamic tuaj yeem tshem cov khoom muaj protein, cov rog thiab lwm cov organic muaj teeb meem sab hauv cov khoom siv kom ntseeg tau tias muaj kev nyab xeeb thiab kev nyiam noj.
Khoom Siv Khoom Siv Papermaking:Thaum lub sij hawm lub papermaking txheej, ntoo pulp fibers, fillers thiab lwm yam yeeb tshuaj zoo li yuav suav rau sab hauv phab ntsa ntawm cov raj xa dej. Cov kua qaub sulfamic tuaj yeem tshem tawm cov av no thiab txhim kho qhov zoo ntawm lub sam thiaj.
Yam kom nco ntsoov thaum tu sulfamic acid pipelines
Txawm hais tias sulfamic acid muaj ntau yam zoo hauv kev tu pipeline, cov ntsiab lus hauv qab no yuav tsum tau sau tseg hauv cov ntawv thov kev siv:
Concentration tswj:Qhov concentration ntawm sulfamic acid yuav tsum tau xaiv kom tsim nyog tau raws li hom thiab qib av. Yog hais tias lub siab tseem ceeb dhau lawm, nws yuav yooj yim corrode lub raj dej, thiab yog hais tias kev siab yog tsawg, cov nyhuv ntxuav yuav ua tsis zoo.
Tswj kub:Ua kom sov ntawm kev ntxuav dej yuav pab kom ceev cov tshuaj tiv thaiv, yog li nws yuav tsum tau tswj hwm nyob rau hauv ib qho kev tsim nyog (feem ntau qis dua 60 ° C) ° C).
Lub sij hawm tswj: Kuvf Lub sijhawm tu yog luv heev, cov av tsis tuaj yeem raug tshem tawm kiag li; Yog tias lub sijhawm ntxuav tau ntev dhau lawm, nws yuav yooj yim ua rau cov kab mob tsis tsim nyog rau cov raj xa dej.
Kev tiv thaiv kev nyab xeeb:Sulfamic acid yog corrosive. Cov tsom iav tiv thaiv, hnab looj tes thiab lwm cov khoom tiv thaiv yuav tsum hnav thaum lub sijhawm ua haujlwm kom tsis txhob sib chwv tawv nqaij.
Raws li muaj txiaj ntsig thiab nyab xeeb yeeb nkab tu tus neeg saib xyuas, sulfamic acid ua ib qho tseem ceeb tshaj plaws hauv txoj haujlwm hauv kev lag luam. Los ntawm kev xaiv qhov kev xav, ntsuas kub thiab sijhawm, thiab kev sib raug zoo ntawm cov roj ntsha ua tau zoo, thiab cov kev pabcuam lub neej tuaj yeem txuas ntxiv.
