Qhov sib txawv ntawm Cov Hlau Tsawg Txhuas Txhuas Sulfate Liquid Thiab Iron Free Aluminium Sulfate

Tsis tshua muaj hlau txhuas sulfate kua yog ib qho inorganic tshuaj nrog cov tshuaj formula Al2 (SO4) 3, ib tug mis ntawm 342.15, thiab ib tug ceev ntawm 1.181g / ml (25 degree). Iron free aluminium sulfate yog cov khoom siv dawb crystalline uas yooj yim soluble hauv dej thiab insoluble hauv cawv. Cov tshuaj aqueous yog acidic, thiab lub cev qhuav dej kub yog 86.5 degree . Thaum rhuab mus rau 250 degree, cov dej crystalline ploj. Anhydrous aluminium sulfate pib decompose thaum rhuab mus rau 300 degree. Cov tshuaj tsis muaj dej yog cov siv lead ua dawb nrog cov hlaws zoo li luster. Tab sis rau ntau tus neeg siv, lawv tsis paub txog qhov sib txawv ntawm lawv. Tom ntej no, cia peb saib ze dua ntawm qhov sib txawv ntawm kev ua haujlwm ntawm ob qho no.
Qhov sib txawv ntawm cov hlau tsis tshua muaj txhuas sulfate kua thiab hlau tsis muaj txhuas sulfate yog feem ntau piv los ntawm ob yam: cov yam ntxwv thiab kev siv:
1, Cov yam ntxwv:
Tsawg hlau txhuas sulfate kua yog tsw tsw, hygroscopic, thiab muaj ib tug ceev ntawm 1.69 grams ib milliliter (25 degree). Hlau tsis muaj txhuas sulfate yog cov khoom lag luam, dawb hauv granular lossis thaiv daim ntawv, nrog qhov ceev ntawm 2.71 grams ib milliliter. Qhov kev nkag siab zoo tshaj plaws yog tias yav dhau los yog grey dawb nrog ib qho lus qhia ntawm ntsuab, thaum lub tom kawg yog dawb huv.
2, Kev siv:
Tsis tshua muaj hlau txhuas sulfate kua yog tsuas yog siv rau daim ntawv ua thiab dej purification, raws li ib tug mordant, tanning tus neeg saib xyuas, tshuaj astringent, ntoo preservative, ua npuas ncauj tua hluav taws tus neeg saib xyuas, zoo crosslinking tus neeg saib xyuas ntawm tsiaj kua nplaum thiab curing tus neeg saib xyuas ntawm urea formaldehyde kua nplaum. Hlau dawb aluminium sulfate yog siv rau hauv papermaking, tshwj xeeb dej kho, titanium dioxide ntau lawm, thiab muab tub lim.
Tsawg hlau aluminium sulfate kua suav nrog dej haus. Aluminium sulfate yog ib tug kws kho dej haus tus neeg sawv cev uas purifies tsawg-kub thiab tsawg turbidity tej yam ntuj tso dej. Nws tuaj yeem tshem tawm cov impurities xws li cov khib nyiab tshem tawm, colloids, algae, sediment, thiab cov hlau hnyav hauv cov dej ntuj. Nws yog tsuas yog siv rau purification kev kho mob ntawm kais dej raw dej thiab kuj lug siv nyob rau hauv cov zaub mov kev lag luam.

Zuag qhia tag nrho, qhov sib txawv tseem ceeb ntawm ob yog nyob rau hauv lawv cov morphology thiab purity. Cov kev lag luam sib txawv tuaj yeem xaiv cov hlau tsis huv uas tsis muaj txhuas sulfate lossis tsis muaj purity tsawg hlau txhuas sulfate kua raws li qhov xav tau tiag tiag.
