Scale formation thiab phom sij
Scale yog tshwm sim los ntawm kev siv mus sij hawm ntev ntawm qee lub ntim uas feem ntau nyob rau hauv kev sib cuag nrog dej, thiab ib txheej tuab ntawm impurities yuav loj hlob ntawm phab ntsa sab hauv.
Qhov laj thawj tseem ceeb ntawm kev tsim cov nplai yog: tom qab lub thawv tau boiled rau ntau zaus, calcium sulfate (CaSO4) uas yog me ntsis soluble hauv dej hauv dej yuav ua rau dej nag vim yog dej evaporation, thiab yav tas los yaj calcium bicarbonate (Ca (HCO3)2) thiab magnesium bicarbonate (Mg (HCO3)2) yuav decompose nyob rau hauv boiling dej, tso carbon dioxide (CO2), thiab tsim crystals uas nyuaj rau yaj. Thaum kawg, nplai tau sau thiab tsim.
Scaling yuav cuam tshuam rau kev hloov hluav taws xob ntawm cov khoom siv hluav taws xob hloov hluav taws xob, cov roj khib nyiab, ua kom cov nqi khiav lag luam ntawm cov khoom siv, thiab nyob rau hauv cov xwm txheej hnyav, ua rau cov cuab yeej tsis ua hauj lwm thiab khawb. Nyob rau tib lub sijhawm, scaling ntawm phab ntsa yeeb nkab dej txo cov dej ntws thiab txawm ua rau lub qhov hluav taws xob thaiv.
Cov "dej liab" thiab "dej daj" ntws tawm ntawm cov yeeb nkab dej kuj yog tsim los ntawm kev ua kom ntev ntev thiab corrosion. Yog tias lub thawv siv los tuav cov dej haus, muaj kev pheej hmoo ntawm kev tawg ntawm cov hlau hnyav ions ntau dhau hauv cov dej haus.
Siv silicon phosphorus siv lead ua los tiv thaiv scaling pob los tiv thaiv kev tsim cov nplai
Silicon phosphorus siv lead ua yog cov khoom siv thev naus laus zis uas muaj txiaj ntsig zoo hauv kev tiv thaiv scaling thiab corrosion hauv cov kav dej. Nws cov khoom tseem ceeb, polyphosphate (NaP0:) n, tuaj yeem cuam tshuam thiab cuam tshuam kev loj hlob ntawm calcium carbonate crystals hauv dej, tiv thaiv lawv los ntawm kev tso nyiaj thiab tsim cov nplai.
Thiab nws tuaj yeem tsim kom muaj kev sib txuam lossis kev sib koom ua ke nrog cov calcium, magnesium, thiab hlau ions uas twb tau tsim thiab ua raws li cov yeeb nkab phab ntsa, thiab tom qab ntawd ua tiav qhov kawg scale inhibition nyhuv los ntawm Brownian motion lossis dej ntws. PP tivthaiv hauv silicon phosphorus crystals cais cov tshuaj tiv thaiv ntawm cov pa oxygen hauv dej thiab hlau ions, tiv thaiv cov tshuaj tiv thaiv ntxiv ntawm ferrous hydroxide los tsim cov hlau hydroxide, yog li suppressing tag nrho cov txheej txheem corrosion.
Silicon phosphorus siv lead ua, ua tus neeg saib xyuas kev ruaj ntseg rau cov dej hauv nroog, muaj kev cuam tshuam ob qho kev tiv thaiv corrosion thiab scale inhibition, tiv thaiv cov pa phem thib ob ntawm cov dej. Cov dej kho nrog silicon phosphorus siv lead ua muaj kev noj qab haus huv thiab huv dua. Lub teb chaws Yelemees, Kaus Lim Qab Teb thiab lwm lub teb chaws tau teeb tsa thiab siv cov khoom siv silicon phosphorus siv lead ua ntawm cov kais dej, nrog rau kev siv txhua xyoo ntawm kaum tawm txhiab tons. Tam sim no, cov khoom no tau siv dav hauv cov tsev, tsev kho mob, tsev so, tsev kawm ntawv cov dej kub boilers, hnub ci dej kub, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov cua sov hauv nruab nrab, cov dej txias, thiab cov tshuab cua txias rau ntau lub tshuab.
Lvyuan Water Treatment yog cov chaw tsim khoom saum toj kawg nkaus 5 cov tshuaj kho dej (silicon phosphorus crystals) hauv Suav teb. Tau ntau xyoo lawm, nws tau cog lus rau kev tshawb fawb thiab kev tsim cov tshuaj kho dej, nrog cov cuab yeej tsim khoom zoo heev thiab cov khoom siv ntau lawm. Nws tau dhau los ntawm IS09001 kev tswj hwm qhov system ntawv pov thawj, thiab silicon phosphorus crystals ua raws li United Nations cov qauv dej haus zoo. Nws kuj tau dhau los ntawm kev soj ntsuam kev nyab xeeb ntawm Tuam Tshoj Lub Chaw Tiv Thaiv Kab Mob thiab Tiv Thaiv, ua raws li "Kev Ntsuam Xyuas Kev Nyab Xeeb Kev Nyab Xeeb rau Cov Tshuaj Kho Mob hauv Cov Dej Haus".
