Basic Mixing Method rau Compound Alkali
Kev sib xyaw alkali yuav tsum tau sib tov raws li cov yam ntxwv ntawm cov dej zoo. Feem ntau, cov hauv qab no raug pom zoo:
Cov dej tsis huv me ntsis (pH<6): Dilute at a ratio of 0.5-1 kg/m³
Cov dej tsis zoo (pH<5): Mix at a ratio of 1-2 kg/m³
Cov dej qias neeg heev (pH<4): Small-scale testing is required to determine the dosage.
Kev kho dej khib nyiab Dosing Techniques
Theem Dosing: Ntxiv 60% ntawm tag nrho cov nyiaj ua ntej, tos 30 feeb, thiab tom qab ntawd ntxiv cov nyiaj seem.
stirring thiab Dissolving: Siv lub tshuab stirrer ntawm 60-80 rpm kom sib tov kom huv si.
Kev Saib Xyuas thiab Kev Kho Kom Zoo: Txheeb xyuas tus nqi pH 15 feeb tom qab txhua qhov sib ntxiv.
Cov ntsiab lus ua haujlwm nyab xeeb
Hnav cov hnab looj tes tiv thaiv thiab tsom iav.
Tsis txhob kov ncaj qha nrog cov tshuaj acidic.
Khaws qhov chaw cia kom qhuav thiab zoo -ventilated.
Cov dej kub thaum lub sij hawm sib tov yuav tsum tsis txhob ntau tshaj 40 degree.
