Hafnium hais rau cov khoom siv tshuaj lom neeg
Hafnium hais siv hauv cov cuab yeej siv tshuaj yog cov khoom siv granular)}}}}}}} ommo lossis ntshav atomization (PA). Nws cov tseem ceeb tus nqi nyob rau hauv kev ua haujlwm corrosion zoo, thiab siab {} kub ruaj khov, ua nws cov khoom tseem ceeb rau kev siv cov kua qaub heev xws li cov muaj zog acids heev thiab cov cua sov.
Hauj lwm lawm
Hafnium hais siv hauv cov cuab yeej siv tshuaj yuav tsum muaj cov khoom siv corrosion zoo heev thiab kev ua siab dawb huv siab. Nws yuav tsum muaj kev tiv thaiv zoo heev rau cov kua qaub muaj zog xws li nitricic acid, thiab kub {- kev corrosion kub tsawg dua 0.01 millimeters. Nyob rau tib lub sijhawm, cov ntsiab lus ntawm impurities xws li hlau, npib tsib xee, thiab chloride ions (ib leeg<50ppm) must be strictly controlled to avoid catalytic poisoning or reaction medium pollution, ensuring the purity and continuity of the chemical process.
Thib ob, cov lus yuav tsum tau ruaj khov siab - kub kev ua haujlwm thiab customizable lub cev morphology. Nws tuaj yeem tswj hwm cov qauv kev ruaj ntseg hauv ib puag ncig acidic ntawm cov txheej txheem sib txawv xws li cov tshuaj lom neeg sib xws xws li cov tshuaj lom neeg sib txawv (thiab cov khoom siv hluav taws xob sib txawv
Cov txheej txheem tseem ceeb
Cov txheej txheem ntau lawm yog qhov txheej txheem precision uas sib xyaw ua ke ntawm cov khoom siv haracium, thiab posting {1} {1} {1} {1} {1} {1} Kev kho mob ntawm corrosion, hmoov {1} {{
1, Kev npaj ntawm high- purity hfernium raw khoom
Sib cais thiab huv ntawm hafnium zirconium:
Siv cov txheej txheem sib cais (xws li Mibk thiocyanate system), high {{purity hafound hafes los ntawm zirconium Hafnium Hafnium Forg tshwm sim ees.
Txo melting:
Los ntawm kev siv cov txheej txheem qib siab lossis hluav taws xob nqaj melting (EBM), Hafnium tebchaw yog txo thiab melted rau hauv kev siv cov impurities xws li oxygen (o<600 ppm) and nitrogen (N<100 ppm) to ensure substrate purity of ≥ 99.9%.
2, hmoov acting txheej txheem
Hydrogenation dehydrogenation (HDH) txoj kev (cov txheej txheem tseem ceeb):
Hydrogenation: Kho cov neododymium ingot hauv hydrogen huab cua ntawm 500-800℃c rau ntxias hydrogen maj.
Kev sib tsoo thiab kev sib tsoo: Cov tshuab crushing rau lub hom phiaj loj me me hauv qab ntawm cov huab cua tiv thaiv.
Dehydogenation: Dehydogenation yog nqa tawm hauv lub tshuab nqus tsev siab ntawm 800-1000 Degree C kom tau cov lus Hafnium zoo li cov khoom muaj tshwj xeeb.
Plasma Atomization (PA) txoj kev (siab -} kev xav tau):
Melt siab - purity} electrode pas nrig rau hauv cov kua dej los ntawm ntshav arc nyob rau hauv qhov chaw inert.
Droplets txias rau hauv cov khoom siv sib tw heev thaum lub davhlau, nrog cov ntshiab zoo thiab cov ntsiab lus oxygen, tab sis ntawm tus nqi siab dua.
3, kev ua dua tshiab thiab muab qhab nia
Kev Ntsuam Xyuas thiab Cov:
Los ntawm kev siv tshuaj ntsuam xyuas thiab siv tshuab pa hluav taws xob, cov hmoov yog qhov tseeb tau muab cais rau hauv qhov muaj ntau qhov loj me (xws li 1-45 μ m, 45-150 μ m).
Nto Kho
Acid Ntxuav: Siv cov acid ras acid (xws li hf {{0} hno} hno α) los ntxuav cov oxides kom huv thiab paug.
Kev Kho Mob Passivation: Ua cov zaj duab xis tuab rau ntxiv txhim kho kev txhim kho corrosion.
Kev Kuaj Xyuas:
Kev Tshawb Xyuas Kev Tshawb Xyuas: GDMS tshawb xyuas cov ntsiab lus purity thiab impurity cov ntsiab lus.
Kev Kuaj Xyuas: Ua cov kev xeem corrosion (xws li soaking hauv 70% nitric acid), particle loj kev faib tawm thiab kev ntsuam xyuas nyo.
4, ntim thiab ntim khoom
Ntim yuav tsum tau ua nyob rau hauv cov inert agosphere (xws li argon) lossis nqus ib puag ncig kom tiv thaiv oxidation thiab noo noo nqus thaum thauj mus los thiab chaw khaws khoom.
Daim ntawv lo nrog cov ntaub ntawv xws li particle loj, huv si, thiab lwm yam. Txhawm rau kom ntseeg tau tias muaj traceability thiab nyab xeeb siv.
