Ditel Boehmite Testing Proses

Boehmite, em i wanpela bikpela mineral we i gat aluminium long en, na planti taim ol i save yusim long ol samting bilong helpim ol 'catalyst', ol 'lithium battery separator coating', na ol 'ceramics'. Long meksua olsem klinpela bilong en, kristal straksa, na ol samting bilong en i stret wantaim ol standet bilong indastri, ol i mas mekim wanpela gutpela tes proses bilong kontrolim kwaliti bilong en. Ol dispela em ol bikpela step na teknikel poin bilong testim 'boehmite'.

I. Sampol Pretreatmen

Ol i mas tritim ol sempel bilong 'Boehmite' pastaim long ol i testim long kisim stretpela 'analytical results'. Pastaim, grisim 'raw sample' i go inap long 200 'mesh' o moa yet yusim wanpela 'grinder' na draim long aven long 105 digri -110 digri inap 2-pela aua long rausim wara i stap insait long en. Sapos tes i gat ol 'surface functional groups' o ol 'organic impuritis', ol i mas klinim moa wantaim 'anhydrous ethanol' na 'vacuum drying' bilong stopim ol 'residual solvent' long bagarapim wok painimaut bihain.

II. Testing bilong ol samting bilong bodi
1.Particle Size Distribution: Wanpela laser particle size analyzer (olsem Malvern Mastersizer) i save yusim long skelim patikel sais bilong ol boehmite patikel. D50 (median diameter) em i save stap namel long 0.5 na 5 μm long inapim ol samting we ol narapela aplikesen i laikim.

2.Spesifik Surface Area: Ol i save skelim spesifik pes eria long rot bilong BET nitrogen adsorption rot (olsem Micromeritics ASAP 2020). Hai-klinpela 'boehmite' i save gat wanpela 'specific surface area' bilong 5 i go inap 20 m2/g, we i save afektim 'catalytic activity' na 'coating uniformity'.

3.Crystal Morphology: Ol i save yusim 'scanning electron microscopy' (SEM) long lukluk long 'particle morphology'. Boehmite i save soim wanpela 'flake-' o 'fibrous' straksa. Morfolojik konsistens em i wanpela ki indiketa bilong ol hai-aplikesen.

III. Kemikel Komposisen na Puriti Analisis
1.Kemikel Komposisen: Ol i save mekim wok painimaut long Al2O3 long rot bilong X-ray fluorescence spectroscopy (XRF) o inductively coupled plasma optical emission spectroscopy (ICP-OES). Indastriel-gred boehmite i nidim wanpela Al2O3 klinpela we i winim o wankain olsem 95%, na hai-klinpela boehmite i nidim wanpela klinpela we i winim o wankain olsem 99%.

2.Painim ol pipia: ICP-MS o atomik absopsen spektroskopi (AAS) em ol i save yusim long painimaut ol liklik pipia olsem SiO2, Fe2O3, na Na2O. Ol samting insait long en i mas i gat liklik mak tasol long abrusim ol samting bilong en.

IV. Karakterisasen bilong straksa bilong kristal
1.X-ray Diffraction (XRD): Ol i yusim ol Bragg diffraction peaks long konfemim -AlOOH kristal fom bilong boehmite na skelim mak bilong kristaliniti. Standet boehmite i soim ol mak bilong difraksen long 2θ mak bilong 14 digri i go inap 35 digri. Sapos i gat ol pipia (olsem -Al₂O3) i ken soim olsem - i gat planti 'calcination'.

2.Thermogravimetric Analysis (TGA): Hatim i go inap 1000 digri insait long win na lukluk long 'weight loss curve'. Boehmite i save bagarap i go long -Al2O3 namel long 300 digri na 500 digri. Ol i ken yusim 'weight loss rate' long sekim hamas 'hydroxyl' i stap insait long en.

V. Funksenel Testing (Opsenel)

Long ol spesifik aplikesen, pH mesamen (planti taim 7-9), oil absopsen tes (long skelim dispersibiliti), o porositi analisis (olsem 'mercury intrusion porosimetry') tu i ken kamap long inapim ol spesifik rikwaemen bilong ol sapot bilong katalis o ol samting bilong bateri.

Long tok sot, wok bilong testim ol 'boehmite' i nidim wanpela 'multi-dimensional analysis we i bungim ol 'physical', 'chemical', na 'crystallographic' wok painimaut long mekim gutpela na gutpela wok na givim kwaliti asurens long ol wok daunstrim.
