Cov dej siv hauv kev lag luam feem ntau raug kev puas tsuaj los ntawm kev sib tsoo thiab xeb, uas cuam tshuam rau kev ua haujlwm zoo thiab lub neej ua haujlwm ntawm cov khoom siv. Nrog kev txhim kho cov qauv kev kho dej hauv kev lag luam, cov tshuaj kho dej ruaj khov thiab zoo rau ib puag ncig tau siv dav hauv kev tsim khoom niaj hnub no.Etidronic Acid (Hydroxyethylidene Diphosphonic Acid, CAS: 2809-21-4)yog ib qho tshuaj organophosphorus scale thiab corrosion inhibitor uas ua haujlwm tau zoo heev. Nws ua ke cov chelating, dispersing thiab film-forming functions, ua haujlwm ua lwm txoj hauv kev zoo rau cov phosphate thiab cov tshuaj lom corrosion inhibitors. Nws tau siv dav hauv kev ncig dej txias, cov khoom siv dej ntshiab, cov dej ua haujlwm tshuaj lom neeg thiab ntau lwm yam kev lag luam.

I. Cov Khoom Siv Lub Cev thiab Tshuaj Lom Zem Tseem Ceeb ntawmEtidronic Acid

Etidronic Acidtau muab khoom lag luam hauv ob qho tib si kua thiab khoom khov kom haum rau ntau yam ntim khoom, kev thauj mus los thiab kev xav tau ntawm qhov chaw. Kua HEDP yog cov kua tsis muaj xim rau daj daj ntseg, thaum cov khoom khov HEDP zoo li cov hmoov dawb crystalline lossis granules. Cov kua qib kev lag luam tswj cov ntsiab lus nquag tshaj 50%, thiab cov khoom khov kho siab ncav cuag ntau dua 98% purity nrog cov dej noo tsawg.

Ib qho txiaj ntsig tseem ceeb ntawm HEDP yog nws cov qauv molecular ruaj khov yam tsis muaj cov POP bonds yooj yim hydrolyzable. Cov polyphosphates inorganic ib txwm muaj feem yuav tawg ntawm qhov kub siab tshaj 60 ° C, ua rau muaj qhov ntsuas thib ob thiab ua rau cov dej tsis muaj zog. Qhov sib txawv, HEDP tiv taus hydrolysis nyob rau hauv kev ua haujlwm kub ntev, nrog rau qhov kub thiab txias thermal decomposition siab dua 200 ° C. Nws tuaj yeem dosed ncaj qha ntawm chav tsev kub hauv daim ntawv kua lossis yaj sai sai ntawm qhov chaw hauv daim ntawv khov. Ib qho 1% Etidronic Acid aqueous kua tswj lub pH ruaj khov ntawm 2.0–3.0. Ob qho tib si kua thiab khoom khov qhia tau tias dej solubility zoo thiab sib xws dispersion nyob rau hauv cov dej kub sib txawv. Cov tshuaj ua haujlwm diluted tseem ruaj khov yam tsis muaj nag lossis stratification pom tseeb thaum lub sijhawm ua haujlwm ib txwm muaj.

II. Cov Txiaj Ntsig Tseem Ceeb: Vim li cas rauCov tshuaj Etidronic AcidTxoj Haujlwm Ruaj Khov Hauv Kev Lag Luam Tshuaj Kho Dej

1. Kev Ua Haujlwm Zoo Dua & Txo Cov Nqi Ua Haujlwm Tag Nrho

Etidronic Acid muaj cov viscosity qis thiab kev sib xyaw ua ke zoo heev, sib xyaw ua ke zoo nrog cov neeg sawv cev ua ntej zaj duab xis, cov tshuaj dispersants thiab lwm yam tshuaj kho dej. Tsis tas yuav muaj cov khoom siv cua sov rau kev siv tshuaj txhua hnub, ua kom yooj yim rau kev ua haujlwm ntawm lub cev thiab txo qis kev siv zog pab. Piv nrog cov khoom polyphosphate ib txwm muaj, Etidronic Acid tuaj yeem txo qhov kev siv zog tag nrho ntawm lub cev thiab txo cov tshuaj zoo hauv qab cov xwm txheej kho mob sib npaug. Nws lub neej ntev ntawm lub lauj kaub txo qis qhov zaus hloov cov tshuaj, txiav cov neeg ua haujlwm tes thiab cov tshuaj pov tseg thaum lub sijhawm ua haujlwm ntev. Rau cov kab ke dej loj thiab cov khoom siv dosing tsis siv neeg, HEDP xa cov kev ua haujlwm kho mob ruaj khov thiab sib xws, pab cov chaw tsim khoom ruaj khov kev tswj hwm dej zoo txhua hnub thiab txo qis kev siv nyiaj ua haujlwm.

2. Kev Tiv Thaiv Qhov Ntsuas Zoo Tshaj Plaws & Kev Tiv Thaiv Hlau Mus Ntev

Etidronic Acidua haujlwm los ntawm ob txoj hauv kev ntawm chelation thiab lattice distortion. Nws ntes cov calcium dawb, magnesium thiab lwm yam hlau ions tsim nplai hauv dej los tsim cov chelates ruaj khov, txwv tsis pub ntsev crystallization thiab deposition. Lub caij no, nws cuam tshuam kev loj hlob ntawm cov qauv microcrystalline, tiv thaiv cov khaubncaws sab nraud povtseg tawv thiab compact los ntawm kev txuas rau phab ntsa yeeb nkab thiab cov chaw pauv cua sov. Hauv cov dej siab-hardness, siab-alkalinity thiab siab-chloride qhov twg cov tshuaj inhibitors ib txwm muaj teeb meem kom tswj tau qhov ruaj khov, Etidronic Acid txhawb nqa cov teebmeem tswj qhov nplai txhim khu kev qha.
Hais txog kev tiv thaiv xeb, HEDP Scale thiab Corrosion Inhibitor nqus cov pa roj carbon thiab stainless hlau kom sib npaug zos rau ntawm cov hlau thiab stainless hlau kom tsim cov zaj duab xis tiv thaiv ntom ntom. Cov zaj duab xis cais cov pa oxygen thiab cov ions corrosive los ntawm kev sib cuag nrog cov hlau substrates, ua rau qeeb qeeb ntawm cov nqi electrochemical corrosion zoo. Rau cov khoom siv khiav ntev xws li cov cua sov sib pauv, boilers thiab cov kav dej ncig, Etidronic Acid pab txo qhov xeb pitting thiab xeb sib npaug, txuas ntxiv cov voj voog kev pabcuam khoom siv thiab txo qis kev saib xyuas tsis tau xav txog los ntawm kev ntsuas thiab xeb.

3. Cov yam ntxwv zoo rau ib puag ncig & Ua raws li cov cai thoob ntiaj teb

Etidronic Acid yog cov khoom siv kho dej uas tsis muaj tshuaj lom, tsis ua rau mob qog noj ntshav thiab lwj tau. Nws hloov kho raws li cov qauv ib puag ncig thoob ntiaj teb thiab cov lus qhia txog kev nyab xeeb hauv chaw ua haujlwm. Tsis muaj cov khoom tsis zoo uas raug tso tawm thaum lub sijhawm siv, tsim kom muaj kev nyab xeeb dua rau cov neeg ua haujlwm hauv chaw ua haujlwm. Tom qab siv, HEDP tsis tsim cov tshuaj lom uas nyob mus ib txhis, ua raws li cov kev cai tso tawm cov dej khib nyiab hauv kev lag luam. Cov ntaub ntawv txheem xws li COA thiab MSDS tuaj yeem muab los txhawb kev xa khoom mus txawv teb chaws thiab kev lees txais ntawm cov neeg siv khoom.

III. Cov Xwm Txheej Tseem Ceeb ntawm Daim Ntawv ThovEtidronic Acid

Tau txais txiaj ntsig los ntawm nws cov kev ua tau zoo hauv kev txwv tsis pub ntsuas, kev tiv thaiv xeb thiab kev tawg, Etidronic Acid ua haujlwm ua cov khoom siv tseem ceeb rau ntau yam kev kho dej hauv kev lag luam:
