Taw qhia rau Aluminium Sulfate
Aluminium Sulfate yog dab tsi?
Aluminium Sulfate yog ib qho tseem ceeb ntawm cov tshuaj inorganic dav siv hauv kev kho dej, kev tsim ntawv, textiles, thiab lwm yam kev lag luam. Nws cov tshuaj formula yog Al₂(SO₄)₃, thiab feem ntau nws yog tsim los ntawm reacting txhuas hydroxide los yog bauxite nrog sulfuric acid.
Hauv kev lag luam kev lag luam, aluminium sulfate feem ntau muaj nyob rau hauv ntau hom, suav nrog:
Hmoov
Granular
Flake los yog pob
Cov ntawv no raug xaiv nyob ntawm kev thauj mus los, kev cia khoom, thiab kev sib cais.
Los ntawm kev pom tshuaj, aluminium sulfate muaj ntau yam khoom uas ua rau nws muaj txiaj ntsig zoo hauv kev siv:
Cov dej solubility siab, tso cai rau nws kom yaj sai sai hauv kev kho tshuab
Acid xwm, uas pab tswj pH hauv qee cov txheej txheem
Muaj peev xwm coagulation muaj zog, ua kom tshem tawm cov khoom tshem tawm thiab cov impurities
Vim tias cov yam ntxwv no, txhuas sulfate tau dhau los ua cov tshuaj tseem ceeb rau ntau txoj kev kho mob.
Vim li cas Aluminium Sulfate tau dav siv hauv kev lag luam
Aluminium sulfate yog dav siv thoob plaws ntau lub lag luam vim muaj ntau yam tseem ceeb.
Ua ntej, nws muaj kev coagulation zoo heev, ua rau nws muaj txiaj ntsig zoo ntawm kev tshem tawm cov khib nyiab thiab colloidal hais los ntawm dej thiab cov kua dej ua haujlwm.
Qhov thib ob, aluminium sulfate yog tus nqi -zoo piv nrog ntau lwm cov coagulants, xws li cov polymers tshwj xeeb lossis cov tshuaj kho mob siab heev. Qhov no ua rau nws txaus nyiam rau loj - thaj chaw hauv nroog thiab kev lag luam.
Thib peb, nws tau sib xws nrog ntau hom kev kho mob, suav nrog cov nroj tsuag dej haus, cov dej khib nyiab, cov ntawv mills, thiab textile factories.
Vim li no, txhuas sulfate tau ntev tau lees paub tias yog ib qho ntawm cov tshuaj inorganic siv dav hauv kev kho dej thoob ntiaj teb thiab kev lag luam tshuaj.
Kev Lag Luam Kev Kho Dej (Daim Ntawv Thov Loj)
Daim ntawv thov loj tshaj plaws ntawm aluminium sulfate yog hauv kev kho dej. Kev siv dej hauv nroog thiab cov nroj tsuag kev lag luam siv nws feem ntau ua cov coagulant thawj.
