| Lus Cim: cov ntsuas ntawm Fe, As, Pb, Cd, Hg, Cr, thiab cov tshuaj tsis yaj uas teev nyob rau hauv cov khoom ua kua hauv lub rooj yog suav ua 10% ntawm AL2O3. Thaum cov ntsiab lus ntawm AL2O3 yog ≤ 10%, cov ntsuas kev tsis huv yuav tsum raug suav ua 10% ntawm cov khoom AL2O3. | ||
Txoj kev siv
Cov khoom lag luam yuav tsum tau yaj thiab diluted ua ntej nkag. Cov neeg siv tuaj yeem lees paub qhov zoo tshaj plaws ntim ntim los ntawm kev sim thiab npaj tus neeg sawv cev concentration raws li cov dej sib txawv.
● Khoom: 2-20%.
● Khoom ntim khoom ntim: 1-15g / t.
Cov khoom ntim tshwj xeeb yuav tsum raug rau kev sim flocculation thiab kev sim.
Packing thiab Cia
Txhua 25kg ntawm cov khoom lag luam yuav tsum tau muab tso rau hauv ib lub hnab nrog cov yas zaj duab xis sab hauv thiab cov hnab yas sab nraud. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw qhuav, qhov cua thiab qhov chaw txias hauv lub qhov rooj vim ntshai tsam ntub. Tsis txhob cia lawv ua ke nrog cov khoom tawg, corrosive thiab tshuaj lom.
