Boehmite Testing kalpui dan chipchiar tak

Aluminium-based mineral pawimawh tak Boehmite hi catalyst support, lithium battery separator coating, leh ceramics-ah te hman a ni nasa hle. A thianghlimna, crystal structure leh physical property te chu industry standard a tlin theih nan quality control atan systematic testing process neih a ngai a ni. A hnuaia tarlan te hi boehmite testing atana step pawimawh leh technical point te chu a ni.

I. Sample Pretreatment neih hmasak ber tur

Boehmite sample te hi test hmain pretreated a ngai a, chu chuan analytical result dik tak a siam thei ang. A hmasa berin raw sample chu grinder hmangin 200 mesh emaw a aia tha zawkah grind la, oven-ah 105℃-110 degree-ah darkar 2 chhung vawt la, adsorbed moisture chu paih chhuak rawh. Test-ah hian surface functional group emaw organic impurities emaw a tel a nih chuan anhydrous ethanol hmanga tihfai belh leh vacuum drying a ngai a, chu chu residual solvent-in a hnua analysis a tihbuai loh nan a ni.

II. Taksa thil neih Testing
1.Particle Size Distribution: Boehmite particle te particle size range tehna atan laser particle size analyser (Malvern Mastersizer ang chi) hman a ni. D50 (median diameter) hi application scenario hrang hranga mamawh phuhruk nan 0.5 leh 5 μm inkar control a ni tlangpui.

2.Specific Surface Area: A surface area bik chu BET nitrogen adsorption method (Micromeritics ASAP 2020 ang chi) hmanga teh a ni. High-purity boehmite hian a tlangpuiin surface area bik 5 to 20 m2/g a nei a, hei hian catalytic activity leh coating uniformity direct-in a nghawng a ni.

3.Crystal Morphology: Scanning electron microscopy (SEM) hmangin particle chi hrang hrang awm dan enfiah a ni. Boehmite hian a tlangpuiin flake-like emaw fibrous structure emaw a lantir thin. Morphological consistency hi high-end application atan chuan key indicator a ni.

III. Chemical Composition leh Thianghlimna thlirletna
1.Chemical Composition: Al2O3 awm zat quantitative analysis chu X-ray fluorescence spectroscopy (XRF) emaw inductively coupled plasma optical emission spectroscopy (ICP-OES) hmangin an ti a. Industrial-grade boehmite hian Al2O3 thianghlimna 95% aia tam emaw, a tlukpui emaw a mamawh a, high-purity boehmite erawh chuan 99% aia thianghlimna sang zawk emaw, a tlukpui emaw a mamawh thung.

2.Impurity Detection: ICP-MS emaw atomic absorption spectroscopy (AAS) hmangin bawlhhlawh trace SiO2, Fe2O3, leh Na2O te chu hriat theih a ni. An thupui (content) chu khauh taka tihkhawtlai a ngai a, chu chu thil awm dan (material property) a nghawng loh nan a ni.

IV. Crystal Structure awmzia sawifiahna
1.X-ray Diffraction (XRD): Bragg diffraction peaks hmangin boehmite-a -AlOOH crystal form finfiah leh crystallinity℃chhut a ni. Standard boehmite hian 2θ range 14℃atanga 35℃inkar ah characteristic diffraction peaks a nei a . Thil bawlhhlawh (-Al2O3 ang chi) awmna hian over-calcination a tilang thei.

2.Thermogravimetric Analysis (TGA): Thli boruakah 1000℃thlenga lum a, taksa rihna tihtlem dan enfiah. Boehmite hi a tlangpuiin 300℃leh 500℃inkar ah -Al2O3 ah a chhe thin. Weight loss rate hmang hian hydroxyl awm zat finfiah theih a ni.

V. Functional Testing (A duhthlan theih) .

A hmanna bik atan chuan catalyst support emaw battery material emaw mamawh bik phuhruk nan pH tehna (a tlangpuiin 7-9), oil absorption testing (dispersibility tehna atan), emaw porosity analysis (mercury intrusion porosimetry ang chi) te pawh a ngai thei bawk.

A tawi zawngin, boehmite testing process hian physical, chemical, leh crystallographic analysis te inzawmkhawma multi-dimensional analysis a mamawh a, chu chuan performance nghet leh rintlak a nih theih nan leh downstream application-a quality assurance a pe thei a ni.
