Dab tsi yog cov ntsuas tseem ceeb kom tsom rau thaum yuav polyaluminum tshuaj lis?

Thaum YuavPolyaluminium chloride(PAC), cov txheej txheem dav siv cov txheej txheem dej kho mob, ob peb lub cim tseem ceeb yuav tsum tau ntsuas kom cov khoom lag luam uas tsim nyog rau nws cov ntawv thov. Hauv qab no yog cov ntsuas tseem ceeb kom tsom rau:

1. Aluminium cov ntsiab lus

Tus thawj kev nquag tiv thaiv hauv PAC yog txhuas. Qhov ua tau zoo ntawm PAC ua cov sib xyaw ua ke nyob ntawm kev xav ntawm aluminium. Feem ntau, cov ntsiab lus txhuas hauv PAC yog qhia raws li feem pua ​​ntawm al2o3. High-zoo pac feem ntau muaj nyob nruab nrab ntawm 28% mus rau 30% al2o3. Cov ntsiab lus txhuas yuav tsum tau txaus los xyuas kom meej cov kev ua kom zoo dua yam tsis muaj kev lag luam ntau dhau, uas tuaj yeem ua rau muaj kev lag luam tsis zoo thiab muaj feem cuam tshuam zoo.

2. Yooj Yim

Cov theem pib yog kev ntsuas ntawm cov degree ntawm hydrolysis ntawm cov noob txhuas hauv PAC thiab yog qhia raws li feem pua. Nws qhia txog qhov sib piv ntawm hydroxide rau aluminium ions hauv kev daws. PAC nrog qhov yooj yim ntawm 40% rau 90% feem ntau nyiam rau cov ntawv thov kev kho dej. Ib qho siab dua yooj yim tshaj plaws cuam tshuam ntau dua cov dej num ntau dua tab sis yuav tsum tau sib npaug ntawm cov txheej txheem kev kho dej tshwj xeeb kom tsis txhob dhau los yog kev kho mob.

4. Kab laum ntau qib

Lub xub ntiag ntawm cov impurities xws li cov hlau hnyav (piv txwv li, txhuas, cadmium yuav tsum tsawg. Cov impurities no tuaj yeem ua rau cov kev pheej hmoo txaus siab thiab cuam tshuam kev ua yeeb yam ntawm PAC. High-Purity Pac yuav muaj tsawg theem ntawm cov dej paug tsis zoo no. Cov ntaub ntawv tshwj xeeb muab los ntawm cov tuam txhab yuav tsum muaj cov ntaub ntawv ntawm qhov siab tshaj plaws uas muaj kev cia siab ntawm cov impurities.

6. Daim ntawv (khoom lossis kua)

Pacmuaj nyob rau hauv ob qho tawv nqaij (hmoov lossis granules) thiab cov hom kua. Qhov kev xaiv ntawm cov khoom siv kua thiab kua nyob ntawm qhov xav tau ntawm cov kev kho mob, suav nrog cov khoom siv cia, cov khoom siv cov khoom siv, thiab yooj yim ntawm tuav. Ua kua PAC feem ntau nyiam rau nws yooj yim ntawm kev siv thiab kev sib txawv sai, uas tau xaiv rau lub sij hawm ntev cia thiab kev thauj mus los zoo. Txawm li cas los xij, lub txee lub neej ntawm cov kua luv, yog li nws tsis pom zoo kom yuav cov kua ncaj qha rau kev cia khoom. Nws raug nquahu kom yuav cov khoom khov thiab ua rau nws tus kheej raws li tus piv.

7. Txee lub neej thiab ruaj khov

Qhov kev ruaj ntseg ntawm PAC nyob rau lub sijhawm cuam tshuam nws cov kev ua tau zoo. Cov Khoom Zoo PAC yuav tsum muaj lub neej ruaj khov ruaj khov, tswj hwm nws cov khoom thiab kev ua tau zoo tshaj rau ncua sijhawm. Cia cov neeg mob, xws li kub thiab raug rau cov cua, tuaj yeem muab tso rau hauv qhov chaw txias, qhuav hauv cov ntim kaw cia kom nws zoo.

8. Tus nqi-ua hauj lwm zoo

Ntxiv rau cov khoom zoo, nws kuj tseem yuav tsum xav txog tus nqi-ua tau zoo ntawm kev tshaj tawm. Sib piv cov nqi, ntim khoom, kev thauj mus los, thiab lwm yam ntawm cov khoom sib txawv los nrhiav cov khoom lag luam uas haum tus nqi haum.

Hauv cov ntsiab lus xaus, thaum kev yuav polyaluminum chloride, solubility, ua kom paub, cov txiaj ntsig, cov txiaj ntsig nqi, thiab kev tswj hwm kev ua raws. Cov ntsuas no suav tau txiav txim siab qhov kev haum thiab ua haujlwm ntawm PAC rau ntau cov ntawv thov kev kho dej.
