Vim li cas HDPE Geomembrane yog qhov nyiam Liner rau Liab av nkos hauv Alumina Refineries

Taw qhia

Liab av nkos, tseem hu uabauxite residue, yog ib qhov loj tshaj plaws kev lag luam pov tseg ntws tawm thaum lub sij hawm Bayer txheej txheem ntawm alumina ntau lawm. Txhua tuj ntawm alumina tsim tsim kwv yees li1-1.5 tons ntawm av nkos liab, uas muaj alkaline caustic cawv heev nrog pH feem ntau tshaj 12.

Vim nws qhov xwm txheej corrosive, kev cia tsis raug ntawm cov av nkos liab tuaj yeem ua rau muaj kev paug ib puag ncig hnyav, suav nrog kev ua qias tuaj hauv av, av degradation, thiab ntev - lub sij hawm ecological puas tsuaj. Yog li ntawd, xaiv ib qho kev txhim khu kev ruaj ntseg liner yog qhov tseem ceeb rau kev ua kom muaj kev tiv thaiv ib puag ncig thiab kev ua raws cai.

High Density Polyethylene (HDPE) Geomembranetau dhau los ua kev lag luam- cov ntaub ntawv txheej txheem rau cov av nkos liab vim nws cov tshuaj tiv thaiv zoo heev, tsis tshua muaj permeability, thiab tshwj xeeb ntev - lub sij hawm durability.

Kev sib tw ntawm Red Mud Storage

Liab av nkos pas dej ua haujlwm nyob rau hauv qee qhov kev mob hnyav tshaj plaws uas tau ntsib hauv cov ntawv thov kev lag luam. Lub liner system yuav tsum tiv taus:

Highly alkaline caustic liquor (pH >12)

Kev raug tshuaj lom neeg tsis tu ncua
