1. Kev puas tsuaj ntawm cov dej nyuaj rau kev ntxhua khaub ncaws
Lub hardness ntawm dej yog hais txog cov ntsiab lus ntawm ntsev yaj nyob rau hauv dej, uas yog, cov ntsiab lus ntawm calcium ntsev thiab magnesium ntsev.Cov ntsiab lus siab dua, qhov siab dua qhov hardness, vice versa.GPG yog chav dej hardness, 1GPG txhais tau hais tias cov ntsiab lus ntawm hardness ions (calcium thiab magnesium ions) hauv 1 nkas loos dej yog 1 lis.
Tus qauv ntawm cov dej nyuaj:
Raws li American WQA (Water Quality Association) tus qauv, qhov nyuaj ntawm cov dej tau muab faib ua 6 qib.0 - 0.5GPG yog dej mos, 0.5 - 3.5GPG yog ib qho nyuaj me ntsis, 3.5 - 7.0GPG yog nruab nrab nyuaj, 7.0 - 10.5GPG yog dej tawv, 10.5 - 14.0GPG yog ib qho nyuaj, thiab siab tshaj 14.0GPG yog qhov nyuaj heev.
Cov dej tawv rau kev ntxhua khaub ncaws tuaj yeem muaj qhov tsis zoo.Calcium thiab magnesium ions nyob rau hauv cov dej tawv yog tso rau ntawm cov ntaub, ua rau greying ntawm cov ntaub dawb.Nws yuav cuam tshuam rau qhov dawb thiab hnov, thiab ua rau cov xim ntawm cov ntaub ploj thiab poob nws vividness.Ntxiv mus, calcium thiab magnesium ions tau tso rau ntawm cov ntaub, thiab cov adhesion rau cov fiber ntau muaj zog heev.Nws yog qhov nyuaj heev los ntxuav tawm cov calcium thiab magnesium ions adhering rau cov ntaub thiab ua rau cov ntaub greyed dawb.Txoj hauv kev zoo tshaj plaws los ntxuav cov ntaub dawb hauv cov dej tawv uas tsis muaj lossis tsawg dua grey yog yuav tsum tau ceev faj ua ntej.
Hlau tsis muaj nyob rau hauv dej raws li ib tug hlau, tab sis raws li ib tug ion los yog ib tug ionic compound.Yog tias cov dej zoo li no tau sov los ntxuav cov ntaub, xeb (hlau hydroxide) yuav tsim thiab tso rau ntawm cov ntaub li qee qhov xim av.Nws yuav ua rau cov ntaub dawb tig daj tag nrho thiab ua rau cov ntaub dawb huv ploj mus.Txhawm rau tshem tawm cov nplai hlau no, yuav tsum tau kho tshwj xeeb nrog cov kua qaub.Lwm qhov phom sij ntawm cov hlau hauv dej yog tias nws muaj qee yam catalytic cuam tshuam rau kev decomposition ntawm hypochlorite thiab hydrogen peroxide.Nyob rau hauv lub sij hawm bleaching, yog hlau ions nyob rau hauv ib feem ntawm cov ntaub, nws yuav catalyze lub zog decomposition ntawm hypochlorite los yog hydrogen peroxide, uas yuav ua rau lub zos oxidation cov tshuaj tiv thaiv hnyav thiab ua rau cov ntaub ntawv puas.
2. Cov dej yuav tsum tau ntxuav
Haus dejCov qauv zoo, qee qhov ntsuas tshuaj lom neeg muaj raws li hauv qab no:
PH tus nqi: 6.5 - 8.5
Tag nrho hardness: ≤446ppm
Hlau: ≤0.3mg / L
Manganese: ≤0.1mg / L.
Ntxuav dejcov cai:
PH tus nqi: 6.5 ~ 7
Tag nrho hardness: ≤ 25ppm (zoo dua 0)
Hlau: ≤0.1mg / L
Manganese: ≤0.05mg / L
Cov dej kais dej feem ntau yog siv rau hauv chav ntxhua khaub ncaws ntawm cov tsev so hauv nroog.Cov dej kais dej yog tsim raws li tus qauv ntawm kev siv dej hauv tsev, thiab tsis muaj teeb meem rau tib neeg haus nws.Tab sis raws li kev ntxuav dej, nws yog pom tseeb tsis zoo tagnrho.Yog li ntawd, txhawm rau ua tiav cov kev xav tau zoo tshaj plaws, cov dej ntxuav yuav tsum tau kho rau qee yam.
