Ultrafine graphite hmoovyog ib hom tshwj xeeb ntawm graphite hmoov yam ntxwv los ntawm qhov tsis tshua muaj me me particle loj thiab txhim khu kev ua haujlwm saum npoo. Nws yog tsim los ntawmntuj flake graphitesiv cov thev naus laus zis micronization. Thaum lub particle loj mus txog kwv yees li6–10 μm, cov khoom yog cais raws li ultrafine graphite hmoov.
Ua tsaug rau nws lub cev zoo thiab tshuaj lom neeg ruaj khov, ultrafine graphite hmoov tau dhau los ua cov khoom siv tseem ceeb hauvconductive, lubricating, zog, nuclear, thiab tiv thaiv-kev lag luam ntsig txog.
Raw Khoom rau Ultrafine Graphite Powder
Lub ntsiab raw khoom rau ultrafine graphite hmoov yogntuj flake graphite. Hauv qee cov txheej txheem, roj av coke lossis lwm yam khoom siv carbon yuav raug qhia nyob ntawm lub hom phiaj daim ntawv thov thiab kev ua haujlwm.
High -cov ntaub ntawv purity yog qhov tseem ceeb los xyuas kom meejzoo ib yam particle loj tis, ruaj khov kev ua tau zoo, thiab tsis muaj impurity cov ntsiab lushauv cov khoom kawg.
Cov txheej txheem ntau lawm ntawm Ultrafine Graphite Powder
Ultrafine graphite hmoov feem ntau yog tsim los ntawm kev siv adav hlau milling los yog ultrafine sib tsoo system. Cov txheej txheem tuaj yeem sau tau raws li hauv qab no:
Pub theem
Ntuj flake graphite thiab raw coke yog pub rau hauv lub kaw lus los ntawm kev pub noj injector siv compressed cua.
Siab -Kev sib tsoo ceev
Cov ntaub ntawv nkag mus rau hauv kev sib tsoo chamber, qhov twg ntau lub nozzles teem ib ncig ntawm lub chamber txhajultra-siab- cua nrawm.
Cov khoom sib tsoo thiab rub tawm ib leeg ntawm qhov nrawm, ua rau micronization yam tsis muaj kev sib kis loj.
Kev faib tawm
Cov huab cua uas nqa cov khoom zoo tawm ntawm lub rooj sib tsoo thiab nkag mus rau hauv chav cais.
Coarser hais yog sib cais thiab xa rov qab mus rau lub sib tsoo chamber rau ntxiv milling.
Sau
Tsim nyog ultrafine graphite hmoov yog sau los ntawmcyclone separators thiab hnab lim, xyuas kom meej particle loj tswj.
Los ntawm txoj kev no,uniform ultrafine graphite hmoovnrog tswj particle loj faib yog tau.
Cov khoom tseem ceeb ntawm Ultrafine Graphite Powder
Piv nrog cov pa graphite hmoov, ultrafine graphite hmoov nthuav tawm qhov tseem ceebloj- cuam tshuam txog, suav nrog:
Loj qhov chaw tshwj xeeb
Nce zog saum npoo
Ua kom muaj tshuaj lom neeg ua haujlwm
Txhim kho thermal thiab hluav taws xob conductivity
Muaj zog nqus ntawm electromagnetic tsis
Cov khoom no tshwm sim los ntawm covvolume effect thiab nto nyhuv, ua ultrafine graphite hmoov zoo txaus nyiam rau cov khoom siv siab heev.
Daim ntawv thov tseem ceeb ntawm Ultrafine Graphite Powder
1. Cov khoom siv hluav taws xob
Ultrafine graphite hmoov yog dav siv nyob rau hauvconductive coatings, conductive composites, thiab hlau-graphite composite cov ntaub ntawv, tshwj xeeb tshaj yog rau kev siv pej xeem thiab kev lag luam.
2. Lubrication thiab hnav-Cov ntaub ntawv uas tiv taus
Hauv kev lag luam kev lag luam, ultrafine graphite hmoov ua haujlwm ua ib qhokhoom lubricant, txo kev sib txhuam thiab txhim kho hnav tsis kam nyob rau hauv qhov kub thiab txias lossis siab load.
3. Kev siv roj teeb thiab lub zog
Ultrafine graphite hmoov yog siv rau hauvcov khoom siv roj teebthiab lub zog- ntsig txog cov khoom siv vim nws cov khoom siv hluav taws xob zoo heev thiab kev ruaj ntseg.
4. Nuclear thiab Defense Industries
Hauv kev siv hluav taws xob nuclear thiab kev tiv thaiv, ultrafine graphite hmoov tuaj yeem ua haujlwm raws li aneutron moderator, shielding khoom, los yog structural carbon tivthaiv.
5. Cov khoom siv zaub thiab txheej txheej
Ultrafine graphite hmoov tuaj yeem ua tiav rau hauvgraphite emulsionsrau daim ntaub ntawv xws li cov yeeb yaj kiab yeeb yaj kiab thiab cov txheej txheem ua haujlwm.
6. Catalysts thiab combustion additives
Vim nws qhov kev ua haujlwm siab saum npoo av, ultrafine graphite hmoov tuaj yeem ua raws li ib qhonpaum catalyst lossis catalyst cab kuj.
Cov kev tshawb fawb pom tau tias thaum siv los ua cov khoom siv catalytic loj, ultrafine graphite hmoov tuaj yeem ua tiavmus txog 10 npaug ntawm kev ua haujlwm ntawm cov tshuaj catalystsnyob rau hauv tej yam tshuaj tiv thaiv hydrogenation.
Nyob rau hauv cov khoom foob pob ua ntxaij propellants, ntxiv kwv yees li1 wt% ultrafine graphite hmoovtuaj yeem txhim kho combustion efficiency thiab kev siv cua sov.
Ultrafine Graphite Khoom Manufacturing
Ultrafine graphite hmoov kuj tuaj yeem siv los tsimultrafine graphite khoomlos ntawm cov kauj ruam hauv qab no:
