Dej zoo txheej txheem dej dav hlau | ||||
Tsom xam Kev Tshawb Fawb | Kev ntsuas dej zoo tshaj plaws | Cov txheej txheem dej zoo tsim nyog | Qhov loj tshaj | Kev cuam tshuam rau nws thiab nws cov cav tov |
Turbidity (mg / kg) | Hauv qab 1.5 | Hauv qab 2.0 | Organic teeb meem: tsiaj txhu thiab cov nroj tsuag khib nyiab, cov av qoob, cov kab mob Yam tsis tov hauv av: av nplaum, pob zeb, av microparticles; hlau, manganese thiab lwm oxides | Txuas mus rau xeb, xeb, khov, txhaws, xuas phom |
PH (25 degree) | 6.8 ~ 7.2 | 6.7 ~ 7.5 | - | Corrosive thiab corrosive vim dej acidic los yog alkaline, slurry desizing vim alkaline dej |
Tag nrho cov hardness | Hauv qab no 25 | Hauv qab no 30 | Calcium ion, Magnesium ions | Kev thaij nyhav tuaj yeem yog tshwm sim los ntawm kev zom ntawm dej xeb ntawm lub pobzeb; qhov hluav taws xob xeb yog txuas mus rau hluav taws xob xeb, uas ua rau sab nraud hnyav ntxig, uas ua rau lub rwb thaiv tsev ntawm lub tshuab nyhav qis. |
Tag nrho cov hlau thiab manganese ions (Mg / kg) | Hauv qab no 0.15 | Hauv qab no 0.2 | Ionic oxide, Fe2 +, Mn2 + | Corrosion, xim |
Dawb chlorine molecule (Mg / kg) | Hauv qab no 0.1 | Hauv qab no 0.3 | - | Muaj zog corrosive thiab muaj zog oxidizing |
Tshuaj Chloride (Mg / kg) | Hauv qab no 12 | Hauv qab no 20 | Cl- | Qhov loj tshaj plaws ntawm corrosion, ua kev puas tsuaj rau lub twj paj nruas caij nplooj ntoos hlav |
M-alkalinity (Mg / kg) | Hauv qab no 50 | Hauv qab no 60 | Hnyav (NaHCO3), thiab lwm yam vim ntawm kev kho mob ntawm hydrogen carbonate ion HCO3 | Tsis ua teeb meem ncaj rau cov ntaub, thiab lwm yam. |
Cov Tshuaj Pluag Pluag Noj (COD) (Mg / kg) | Hauv qab no 2 | Hauv qab no 3 | Organic teeb meem, kab mob, pwm, lwm yam zoo li no. | Corrosion, stains ntawm cov ntaub, poob pulp, tsis tshua muaj zaj duab xis lub zog |
Evaporation seem (Mg / kg) | Hauv qab no 100 | Hauv qab no 150 | Tag nrho tus nqi ntawm impurities nyob rau hauv dej | Ua ntau yam teeb meem |
Kev coj cwj pwm (Peb / cm) | 100 ~ 150 | 80 ~ 200 | Kev ua ntawm cov electrodes uas tau sib nrug deb hauv cov dej (nyob ntawm seb cov kua roj electrolyte yaj hauv dej) | Yog hais tias nws yog obviously tsawg, qhov ua haujlwm ntawm lub hwj chim-rau weft ntes yuav impaired; Yog hais tias nws yog siab dhau, nws txhais tau hais tias muaj ntau impurities nyob rau hauv dej, uas ua rau kom hluav taws xob corrosion ntawm kev sojntsuam. |
Dej kub (degree) | 16 ~ 20 | 14 ~ 20 | - | Yog hais tias nws yog siab dhau, qhov phenomenon ntawm poob pulp nce, thiab cov kab mob uas yooj yim mus muab; yog hais tias nws yog tsawg tsawg, lub zog ntawm slurry, wax, thiab lwm yam yog tsawg. Ntau dhau los los yog tsawg dhau yuav ua rau qhov kev nyiag top kawm ua kom poob. |
