Pob zeb diamond Micropowder Rough Purification txheej txheem

Feem ntau, cov khoom siv raw ntawm pob zeb diamond hmoov feem ntau yog qib qis RVD pob zeb diamond lossis pob zeb diamond hmoov synthesized los ntawm txoj kev tawg, thiab cov khoom siv raw nws tus kheej muaj me me ntawm impurities xws li graphite, catalyst hlau thiab pyrophyllite. Nyob rau tib lub sij hawm, ib tug loj npaum li cas ntawm hlau impurities yuav qhia nyob rau hauv lub tom qab crushing thiab shaping txheej txheem. Cov ntsiab lus siab impurity yuav txo tag nrho hardness ntawm pob zeb diamond thiab cuam tshuam rau kev ua haujlwm ntawm cov cuab yeej sib sib zog nqus. Yuav kom ua tau raws li qhov yuav tsum tau ua rau cov khoom purity nyob rau hauv cov txheej txheem muab qhab nia tom ntej, cov impurities yuav tsum tau muab tshem tawm ua ntej xa mus rau cov txheej txheem muab qhab nia.

 

Tam sim no, tshuaj impurity tshem tawm thiab electrolytic purification cov txheej txheem yog feem ntau siv los purify dag pob zeb diamond micropowder. Cov tom kawg yog tsuas yog siv thaum muaj ntau cov alloy catalysts nyob rau hauv cov khoom siv pob zeb diamond, thiaj li ua tiav lub hom phiaj ntawm recycling catalyst hlau. Txawm li cas los xij, hauv kev ua haujlwm tiag tiag, vim qhov qeeb qeeb ntawm cov alloy catalyst thiab kev ua haujlwm tsawg, nws nyuaj rau ua kom tau raws li qhov yuav tsum tau ua ntawm kev tsim khoom. Hais txog kev hais lus, cov txheej txheem tshuaj siv cov tshuaj sib txawv los kho cov impurities cais raws li cov yam ntxwv sib txawv ntawm cov impurities hauv pob zeb diamond, thiab tuaj yeem tau txais txiaj ntsig zoo dua qub, uas yog, "peb tshem tawm" txheej txheem feem ntau siv hauv kev lag luam. : acid tshem tawm ntawm alloy catalyst, muaj zog Lub oxidant tshem tawm graphite, alkali-melted pyrophyllite thiab lwm yam peb-theem ua hauj lwm. Raws li cov tshuaj lom neeg ruaj khov zoo ntawm pob zeb diamond thiab cov yam ntxwv ntawm tsis hnov ​​​​mob nrog cov kua qaub thiab muaj zog oxidant ntawm qhov kub thiab txias, cov txheej txheem tshuaj feem ntau yog siv los ntxuav cov pob zeb diamond.

Lub ntsiab impurity ntawm pob zeb diamond uas tau ua tiav cov txheej txheem crushing thiab shaping yog hlau, uas tuaj yeem ua rau cov tshuaj tiv thaiv redox nrog cov kua qaub los ua cov ntsev ntsev. Siv cov yam ntxwv no, nws tuaj yeem kho nrog cov kua qaub kom tshem tawm feem ntau ntawm cov hlau impurities, thiab tib lub sijhawm Nws tuaj yeem tshem tawm impurities xws li graphite.

 

Txoj kev ua haujlwm dav dav rau kev kho cov kua qaub yog: hnyav ib qho nyiaj ntawm cov pob zeb diamond hmoov, muab tso rau hauv 5000ml iav beaker lossis lwm cov kua qaub-resistant thiab kub-resistant ntim, ntxiv cov kua qaub tsim nyog, thiab tso lub beaker rau ntawm lub khob. hluav taws xob cua sov phaj los yog muaj cua sov phaj nyob rau hauv lub fume hood. Cov cua sov ntawm lub qhov cub hluav taws xob, thaum qhov kub thiab txias, cov tshuaj tiv thaiv maj mam ua kom khaus. Tom qab cov tshuaj tiv thaiv tag lawm, nres cua sov thiab tshem tawm lub thawv los ntawm lub tshav kub. nyob rau hauv cov txheej txheem muab qhab nia.

 

Hauv kev tsim khoom lag luam, txij li qhov kawg kev faib tawm tiav, kev kho kom huv huv zoo yuav tsum tau ua dua. Cov txheej txheem purification ntxhib yuav tsum txo tus nqi ntau li ntau tau raws li qhov ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem kev faib tawm. Cov tshuaj reagents feem ntau siv yog feem ntau muaj kev lag luam ntshiab. Cov lus hauv qab no qhia txog cov txheej txheem purification ntxhib. Cov txheej txheem tshwj xeeb tsis siv nyob rau hauv ntau yam kev kho mob:

Vim cov ntsiab lus tsawg ntawm pyrophyllite thiab graphite hauv pob zeb diamond raw khoom. Txhawm rau ua kom yooj yim txoj kev kho mob, cov txheej txheem kev lim dej dav dav tsis ua haujlwm tshwj xeeb rau nws. Yog tias muaj cov kev cai tshwj xeeb rau cov khoom, tom qab kev faib ua tiav, cov khoom tiav yuav raug kho tshwj xeeb hauv theem tom ntej.

 

Nyob rau hauv cov txheej txheem ntawm pob zeb diamond micropowder, ntau yam tshuaj reagents yog siv nyob rau hauv cov txheej txheem purification, thiab ib tug loj npaum li cas ntawm cov pa phem thiab cov dej khib nyiab yuav raug tso tawm thaum lub sij hawm kev kho mob, uas yuav ua rau muaj kev phom sij rau kev noj qab haus huv ntawm tus neeg teb xov tooj thiab ua phem rau ib puag ncig. Txhawm rau txhim kho tus neeg teb xov tooj qhov chaw ua haujlwm thiab txo cov pa khib nyiab thiab dej pov tseg. Qee lub tuam txhab tsim cov pob zeb diamond micropowder tau pib sim hloov cov txheej txheem purification qub, hloov cov txheej txheem qhib lub tshuab cua sov nrog lub tshuab kaw loj.

 

Cov tshuaj tiv thaiv hluav taws xob txais hluav taws xob cua sov lossis cua sov tsis ncaj ntawm cov roj hluav taws xob, thiab cov khoom siv yog quartz iav lossis steel hauv ob sab phlu nrog enamel. Reactors ntawm ntau yam tshwj xeeb xws li 20 litres, 50 litres, thiab 100 litres tuaj yeem xaiv raws li qhov ntsuas ntau lawm. Cov khoom yog nruab nrog tsis siv neeg stirring, tsis siv neeg kub tswj, pov tseg roj neutralization thiab nqus, thiab acid vapor condensation thiab reflux li. Kev siv cov reactors rau kev kho kom huv tuaj yeem tsis tsuas yog ua kom muaj peev xwm kho tau ib leeg thiab txo qis kev siv zog ntawm cov neeg ua haujlwm, tab sis kuj tseem muaj txiaj ntsig zoo hauv kev txuag hluav taws xob, txhim kho kev ua haujlwm thiab tiv thaiv ib puag ncig.
