High -purity sulfamic acid: Vim li cas ntau thiab ntau lub Hoobkas hloov hydrochloric acid, nitric acid, lossis oxalic acid nrog nws?
Hauv kev lag luam tu thiab kho hlau nto, hydrochloric acid thiab nitric acid tau ntev tuav txoj haujlwm tseem ceeb. Lawv yog cov pheej yig, hnov mob sai, thiab muaj zog descaling peev xwm, uas suab zoo tagnrho. Txawm li cas los xij, cov neeg saib xyuas cov cuab yeej siv thiab cov neeg ua haujlwm hauv chav ua haujlwm uas tau siv tiag tiag paub tias cov teeb meem no ob hom muaj zog acids qee zaum coj ntau dua li cov teeb meem uas lawv daws tau - cov pa roj carbon monoxide choking, cov khoom siv corrodes sai heev, cov nqi kho cov kua dej khib nyiab yog siab, thiab kev nyab xeeb tuaj yeem tshwm sim yog tias tsis ua tib zoo saib xyuas.
Nyob rau hauv xyoo tas los no, ntau thiab ntau lub tsev lag luam tau pib tig lawv cov xim rau sulfamic acid. Nws tsis yog ib yam khoom tshiab, tab sis qhov zoo tshaj plaws uas siab -purity, low- impurity industrial- qib sulfamic acid tau qhia hauv thaj chaw tu tau ua rau ntau tus neeg siv khoom hloov lawv tus cwj pwm.
1. Cov Khoom Muag Khoom thiab Cov Ntsiab Lus Tseem Ceeb
Sulfamic acid yog cov khoom muaj zog acid. Txawm hais tias nws cov tshuaj aqueous yog acidic heev, nws daim ntawv yog ruaj khov heev, yuav luag tsis yog -hygroscopic, thiab yooj yim rau kev thauj thiab khaws cia. Piv nrog cov kua qaub uas nquag siv (xws li hydrochloric acid thiab nitric acid), nws tsis tshua muaj corrosive rau cov ntaub ntawv hlau thaum tseem tuav tau zoo heev descaling peev xwm thiab tshuaj lom neeg kev ua si.
Peb tau tsim tawm tshiab siab -purity aminosulfonic acid ua tau raws li cov kev cai purity nruj ntawm siab -kawg kev lag luam xws li boiler tu, hlau nto kho, hluavtaws desulfurizers, thiab flue gas denitrification. Cov ntsiab lus tseem ceeb yog raws li hauv qab no:
Cov ntsiab lus tseem ceeb: 99.52%
Hlau ions (Fe): 0.83 ppm (deb qis dua tus qauv ntawm 50 ppm, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov khoom siv hlau stainless)
Dej -insoluble teeb meem: 0.009% (tsis txhob clogging nozzles los yog membrane pores)
Tsis tas li ntawd, aminosulfonic acid tsis tshua muaj volatile tshaj hydrochloric acid, ua tsis muaj pungent acid fumes, yog hlau -phooj ywg, thiab piv rau oxalic acid thiab citric acid, calcium aminosulfonate uas tsim nyob rau hauv cov tshuaj tiv thaiv muaj ntau dua solubility, yaug tawm yooj yim nrog dej yam tsis tau tso precipitates rau clog kav.
2.Kev sib piv ntawm tsib acids
|
Hydrochloric acid |
Nitric acid |
Citric acid |
Sulfamic Acid |
|
|
Corrosive |
Muaj zog, yooj yim ua rau hydrogen embrittlement |
Nws muaj zog heev thiab tuaj yeem ua kom puas stainless hlau. |
Tsis muaj zog heev, kuj muaj kev nyab xeeb rau feem ntau cov hlau |
Milder, haum rau stainless hlau |
|
Kev nyab xeeb ua haujlwm |
Nws ua rau khaus kua qaub, xav tau qhov cua thiab kev tiv thaiv. |
Nws tsim cov pa luam yeeb daj (nitrogen oxides), uas muaj kev pheej hmoo siab. |
Khoom hmoov, muaj kev nyab xeeb heev, zaub mov- qib. |
Daim ntawv khov, tsis muaj kua qaub, thiab tsis muaj qhov tseem ceeb volatilization tom qab dissolution. |
|
Descaling ntau |
Nws ua haujlwm zoo rau carbonate nplai, tab sis feem ntau tsis yog rau cov nplai sulfate. |
Siv tau zoo tiv thaiv qee cov oxides, tab sis nws yooj yim rau qhov chaw passivation. |
Ua tau zoo tiv thaiv carbonate nplai, tab sis tsis zoo ntawm kev tshem tawm xeb tshaj oxalic acid. |
Zoo tiv thaiv carbonates, sulfates, xeb, thiab silicates. |
|
Kev kho dej khib nyiab nyuaj |
Nws muaj chloride ions thiab tsis tuaj yeem tso tawm ncaj qha; Nws yuav tsum tau neutralized thiab dechlorinated. |
Muaj nitrates, siab ua nqi |
Nws yog ib qho yooj yim biodegradable, cov dej khib nyiab kuj qias neeg, tab sis nws yog feem ntau yooj yim kho. |
Nws tuaj yeem nruab nrab thiab tawm ncaj qha, thiab muaj biodegradability zoo. |
|
Comprehensive nqi |
Tus nqi ntawm cov kua qaub yog tsawg, tab sis kev hloov khoom siv yog nquag thiab kev kho cov kua khib nyiab yog kim. |
High acid nqi, loj peev yuav tsum tau rau tail gas absorption. |
Tus nqi raw khoom yog siab me ntsis, thiab nws lub peev xwm descaling yog txwv, ua rau nws tsim nyog rau kev saib xyuas lub teeb. |
Tus nqi ntawm cov khoom siv raw yog me ntsis siab dua, tab sis tag nrho cov nqi ntawm kev siv yog qis dua. |
Raws li pom nyob rau hauv cov lus, aminosulfonic acid ua tiav qhov zoo sib npaug ntawm "mildness" thiab "high efficiency"-nws corrosivity yog tswj tau, nws descaling spectrum yog dav, nws cov dej khib nyiab yog qhov yooj yim, thiab nws tag nrho cov nqi yog qhov zoo dua.
3. Cov xwm txheej siv tau
Raws li cov yam ntxwv tau hais los saum toj no, siab -purity aminosulfonic acid tshwj xeeb yog tsim nyog rau qee qhov xwm txheej tshwj xeeb:
Tsis tu ncua descaling ntawm stainless hlau tshav kub exchangers thiab condensers (cov cuab yeej no kuj rhiab heev rau chloride ions)
Cov txheej txheem cov cuab yeej nkag siab rau chloride ions lossis calcium oxalate nag lossis daus
Cov chaw ua haujlwm nyob ze uas yuav tsum zam kom tsis txhob muaj kua qaub pos huab
Cov txheej txheem tshuaj lom neeg uas yuav tsum tau muaj siab purity, xws li flue gas denitrification thiab synthesis ntawm sweeteners.
