| Nco tseg: cov indexes ntawm Fe, As, Pb, Cd, Hg, Cr, thiab insoluble tshuaj teev nyob rau hauv cov kua khoom nyob rau hauv lub rooj yog xam raws li 10% ntawm AL2O3. Thaum cov ntsiab lus ntawm AL2O3 yog ≤ 10%, cov impurity indexes yuav tsum xam raws li 10% ntawm AL2O3 khoom. | ||
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 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 kub, corrosive thiab tshuaj lom.
