Aluminium Sulfate yog dab tsi?

Aluminium sulfate, hu ua chemically as Al₂(SO₄)₃, yog ib qho tshuaj siv ntau yam siv hauv kev tsim kho thiab ntau yam kev lag luam. Nws feem ntau tshwm raws li cov hmoov dawb los yog crystalline khoom. Hauv qab no yog cov ntsiab lus ntawm aluminium sulfate, suav nrog nws cov khoom siv yooj yim, tshuaj lom neeg cov yam ntxwv, thiab kev siv thawj zaug:

Basic Introduction

Aluminium sulfate yog ib qho inorganic compound uas pom kev siv hauv kev kho dej, papermaking, kev tsim kho, thiab textile kev lag luam. Nyob rau hauv kev tsim kho sector, nws yog feem ntau siv raws li ib tug ua vaj tse accelerator thiab regulator, ho txhim khu kev ua tau zoo.

Khoom Parameters

Molecular Formula: Al₂(SO₄)₃

Molecular LujYog ': 342.15 g/mol

Qhov tshwm sim: Dawb crystals los yog hmoov

Purity: Ntau tshaj 98%

Solubility: Yooj yim soluble hauv dej, insoluble hauv ethanol

Chemical Properties

Acidity/Basicity: Cov tshuaj aqueous yog acidic, nrog pH ntawm ib ncig ntawm 3.

Kev ruaj ntseg: ruaj khov thaum qhuav, tab sis nws tuaj yeem nqus dej noo thiab clump hauv cov av noo.

Reactivity: Hauv dej, aluminium sulfate hydrolyzes tsim aluminium hydroxide thiab sulfuric acid, nthuav tawm cov khoom muaj zog flocculating.

Kev siv tseem ceeb

1. Kev kho dej

Aluminium sulfate yog dav siv los ua dej purifier. Nws zoo tshem tawm cov khoom uas raug tshem tawm, colloids, thiab cov organic teeb meem los ntawm dej. Los ntawm hydrolysis, nws tsim aluminium hydroxide, uas pab flocculate thiab precipitate impurities, yog li purifying dej.

2. Papermaking kev lag luam

Hauv kev lag luam papermaking, aluminium sulfate ua tus neeg sawv cev sizing, txhim kho cov dej tsis kam thiab tensile lub zog ntawm daim ntawv. Thaum lub sij hawm sizing txheej txheem, aluminium sulfate khi nrog fibers, ho txhim kho daim ntawv lub cev zog.

3. Kev tsim kho kev lag luam

Hauv kev tsim kho, aluminium sulfate feem ntau yog siv los ua qhov chaw accelerator thiab regulator rau pob zeb. Nws accelerates cement chaw, nce lub zog thaum ntxov, thiab shortens lub sij hawm tsim kho. Tsis tas li ntawd, nws txo qis kev sib cais thiab los ntshav hauv cov pob zeb, txhim kho nws qhov ntom ntom thiab kav ntev.

4. Kev lag luam Textile

Hauv kev lag luam textile, aluminium sulfate ua raws li dyeing thiab luam ntawv pab. Nws tsub kom lub peev xwm adsorption ntawm dyes, ua rau cov txheej txheem dyeing ntau uniform thiab ceev.

5. Lwm yam kev siv

Aluminium sulfate kuj tseem ua haujlwm nyob rau hauv kev tsim cov khoom siv refractory, tshuaj, khoom noj khoom haus ntxiv (xws li cov tshuaj tua kab), nplaim hluav taws, thiab ua cov av txias hauv kev ua liaj ua teb.

Xaus

Raws li kev siv tshuaj lom neeg ntau, aluminium sulfate muaj kev siv dav hauv ntau lub lag luam, tshwj xeeb hauv kev tsim kho. Nws lub cev zoo heev thiab tshuaj lom neeg ua rau nws tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov khoom siv engineering thiab txhim kho kev tsim kho.
