Khoom Taw Qhia
Tsis yog Alfalric Aluminium Sulfate yog cov tshuaj dawb crystalline nrog ib qho kev sib nqus tshwj xeeb ntawm 1.69. Nws tau yooj yim nqus dej noo thiab cov lumps thaum khaws cia hauv huab cua ntev. Nws lub cev qhuav dej kub yog 86. 5 degree. Nws yog soluble hauv dej, acids, thiab alkalis. Cov tshuaj aqueous yog acidic thiab muaj qaub, astringent saj. Raws li cov tshuaj lom neeg, nws pib txiav txim siab ntawm 530 degree thiab ua tiav kev lom zem ntawm {5}} degree, nrog rau cov khoom sib txawv kawg yog cov khoom siv r-al₂o₃. Thaum lub sij hawm hydrolysis ntawm nonfer aluminium sulfate, cov ntsev theem nrab yooj yim yog thawj tsim, ua raws li los ntawm kev tsim cov txhuas hydroxide.
| Zog: |
Khoom txhuas sulfate yog xim dawb, ntsuab lossis lub teeb daj lossis cov kua txhuas, thiab kua txhuas yog lub teeb ntsuab lossis lub teeb daj. |
| Solubility: | Soluble hauv dej, kua qaub thiab alkali, insoluble hauv cawv. |
| Cov tshuaj aqueous: | Cov tshuaj aqueous yog acidic thiab tsim cov txhuas hydroxide tom qab hydrolysis. |
| Ntawj ntom: | Cov kev nqus tshwj xeeb yog 1.69. |
| Thermal Stability: | Nws pib decompose thaum rhuab mus 530 degree thiab xaus ntawm 860 degree. Qhov kawg decomposition khoom yog txhuas oxide (al2o3) |
Sizing tus neeg sawv cev yog qhov papermaking ntxiv uas tuaj yeem muab ntawv thiab cov ntaub ntawv tiv thaiv corrosion thiab lwm cov khoom los txhim kho nws txoj kev pabcuam, lub zog thiab kev pabcuam lub neej. Sizing cov neeg sawv cev tuaj yeem muab faib ua sab hauv cov sitizing thiab cov neeg sawv cev.
Daim ntawv thov
Hmoov txhuas sulfate feem ntau yog siv ua cov flocculant hauv kev kho dej dej, thiab tuaj yeem sib xyaw nrog polyaluminum chloride thiab polyacrylamide rau ib tus neeg sawv cev sib xyaw. Nws kuj tseem siv tau rau hauv papermaking, petrochemical, xis mas accelerator Industries, thiab lwm yam.
Aluminium sulfate yog ib feem ntau siv inorganic flocculant. Nws yog dav siv nyob rau hauv kev kho dej. Nws muaj qhov zoo ntawm cov nqi qis, siv tau yooj yim thiab kho kom zoo. Txawm li cas los xij, thaum siv txhuas sulfate ua cov flocculant, nws yog ib qho tsim nyog los them rau kev tswj hwm xws li nws koob tshuaj thiab pH nqi los xyuas kom cov kev kho mob.
Daim ntawv thov ntawm Aluminium sulfate hmoov nyob rau hauv av tsuas yog tsom rau nws lub luag haujlwm ua qhov kev hloov kho av. Tshwj xeeb, txhuas sulfate hmoov yog siv los txhim kho cov khoom siv roj tais-alkali, kho cov khoom hauv paus, thiab txhim kho cov av muaj zog. Thaum thov kom raug, nws tuaj yeem txhim kho cov av zoo thiab nce qoob loo ntau.
