Kua Aluminium Sulfate

Tshuaj Muaj Tshuaj

• Cov lus ntawm ib txoj kab ke: Al2 (so4) 3al2 (so4) 3 (Ehydrous) lossis Al2) 3⋅18h18h18h2oAd2 (so4) o (octadecahydate).
• Daim foos ua kua: Feem ntau cov tshuaj a aqueous nrog cov kev xav ntau. Industrial-qib kev daws teeb meem nquag muaj 7-8}% al2o3al2 O3.

Cov Khoom Siv Lub Cev

• Kev tshwm sim: Tsis muaj xim rau cov kua daj / ntsuab (xim ntaus nqi rau cov impurities xws li hlau ions).
• So: Heev soluble hauv dej, nrog solubility nce nrog kub.
• pH: Acidic ({{0}}}}}}}}}}}} - 4.0).
• Ceev: Concentration-nyob; Piv txwv li, 20% daws muaj qhov ntom ntom ntawm ~ 1.2-1.3 g / cm³.

Tshuaj Tshuaj Muaj Zog

• Kev txha kas: Tsim kom muaj al (Oh) 3al (Oh) 3 colloids nrog muaj peev xwm adsorption muaj peev xwm, dav siv hauv dej huv huv.
• Acidic tshuaj: Reacts nrog cov hauv paus los ua sulfates thiab al (Oh) 3al (Oh) 3 precipitates.
• Thermal ruaj khov: Decomposes ntawm qhov kub siab rau hauv Al2o3al2 O3, yog li3S13, thiab lwm yam khoom.

Kev Kho Mob Dej

• Coagulant: Tshem tawm cov khib nyiab tshem tawm, colloids, thiab cov organic teeb meem hauv kev siv dej hauv nroog thiab kev lag luam pov tseg.

Kev Lag Luam Ntawv

• Sizing tus neeg sawv cev: Txhawb nqa dej tsis kam, ntawv zog, thiab luam tawm.

Textile Dyeing

• Tus tseem ceeb: Txhim kho cov lus nug los txhim kho cov xim xim thiab kev sib txuam.

Kev tua hluav taws thiab kev lag luam chemical

• Tua hluav taws: Siv rau hauv ua npuas dej-based hluav taws kub kev lag luam.
• Cov khoom siv raw: Kev tsim khoom ntawm Alum, catalysts (xws li, ammonia synthesis), thiab titanium dioxide kev tsim khoom.

Lwm daim teb

• Kev Hloov Pauv Phos, Tshuaj Tiv Thaiv Tshuaj (uas yog ARINGENT), thiab lwm yam.

Industrial-qib vs. Cov Fixed-Qib

• Industrial-Qeb: Muaj ~ {{{{{{0}}}}}}}} 3, nrog cov hlau tsawg dua lossis sib npaug nrog 0.5%).
• Cov dej hauv qab tau muaj peev xwm: Kev coj dawb huv ntau dua nrog cov hlau hnyav ntawm cov hlau hnyav (piv txwv li, arsenic tsawg dua lossis sib npaug}. 0005%).

Kev Pom Zoo Ntau Dua

• Cov khoom ua kua: Feem ntau 6-12% AL2O3AL2 O3, nrog cov kev daws teeb meem siab txog li 17%.
• Cov Khoom Siv Khoom: Ntau dua al2o3al2 O3 cov ntsiab lus (piv txwv li, octadecahydrate muaj ~ 17% al2o3al2 O3).

Daim ntawv thov-tshuaj tshwj xeeb

• Kev Kho Mob Dej: Muab tshuaj npaum li cas los ntawm 5-100 mg / l, kho raws li dej ua tau zoo.
• Ntawv sizing: ~ 1-3% txheeb ze rau pulp huab hwm coj.

• Lom zem: Tsawg toxicity, tab sis feeb meej tej zaum yuav ua rau lub cev nqaij daim tawv nqaij / cov ntaub nyias nyias nyias; PPE xav tau.
• Chaw ntim khoom: Khaws rau hauv cov thawv kaw kom deb ntawm cov tshuaj yeeb yaj kiab thiab alkaline. Kev tiv thaiv khov yog qhov tseem ceeb (crystallization txaus ntshai ntawm tsawg kub).

• Kev tsis sib haum: Sib tov nrog cov tshuaj ua ntej tej zaum yuav daus ib (Oh) 3al (Oh) 3; Kev noj tshuaj ua ntu zus yuav tsum tau tswj (piv txwv li, ntxiv txhuas sulfate ua ntej pH hloov kho).
• Crystallization: Lub sijhawm ntev cia yuav ua rau muaj cov siv lead ua; Rov ua dua cov khib nyiab.
• Lub ntsiab: Kua aluminium sulfate yog ib qho kev sib txuas nrog cov tub rog tseem ceeb hauv kev kho dej, kev tsim khoom, thiab kev tswj hwm ib puag ncig. Kev ua tau zoo tshaj plaws yuav tsum tau txiav kev tswj hwm kev tswj hwm thiab kev ua raws li kev nyab xeeb rau kev nyab xeeb.
