Nyob rau hauv kev lag luam petrochemical, chiv kev lag luam, dav siv ua tus catalyst, catalyst cab kuj. Alumina, dhau los, muaj adsorptive cov khoom thiab yog vim li no siv cov roj ntsha thiab kua ntau dua, ua ib lub teeb rau cov dej purification, ua fluoride tshem tawm sawv cev rau cov dej haus, raws li ib qho xim thiab ntxhiab tshem tawm rau cov kev ua haujlwm.
Yuav siv tau nrog tsev tshuaj fluoride hauv tsev, qhov zoo tagnrho rau cov dej haus cov dej siv tawm hauv tsev neeg. Lub tshuab de-fluoride yuav siv tau nrog dej purification cog fluoride lossis cov khoom siv txhawb kev siv. Lub tshuab de-fluoride ntaus ntawv de-fluoride lim ua kom: Txhim kho cov txhuas tshuaj sulfate (3 litres dej, 0.3kg khoom txhuas sulfate), cov tshuaj fluoride hauv alumina fluoride, ua rau 5-10 teev immersion immersion Thaum tsim nyog tov) thiab tom qab ntawd ces ntxuav nrog dej 3-5 zaug, txhua zaus txog 2 liters dej, los yog kho qhov p ntsuas qub, PH tswj ntawm 7.5. Cov dej ua kom nrov li qub tau siv 6-8 xyoo, thaum lub npo tshwm li xim av, qhov kev siv cov tshuaj fluoride tshem tawm tau txo, Department of water kev tuaj yeem los ntawm impurities, nws yog qhov zoo tshaj uas yuav tau ua nrog rau ib nrab xyoo 3% hydrochloric acid ib zaug, nws tib txoj hauv kev lag luam thiab kev tsim rov qab.
