Cov teb thov ntawm cov hmoov graphite thiab cov hmoov graphite dag

1. Kev lag luam hlau

Hauv kev lag luam hlau, hmoov graphite ntuj siv tau los tsim cov khoom siv refractory xws li magnesium carbon cib thiab aluminium carbon cib vim nws zoo tiv taus oxidation. Hmoov graphite dag siv tau ua electrode ntawm steelmaking, tab sis cov electrode ua los ntawm hmoov graphite ntuj nyuaj rau siv hauv lub cub hluav taws xob ntawm steelmaking.

2. Kev lag luam tshuab

Hauv kev lag luam kho tshuab, cov ntaub ntawv graphite feem ntau yog siv los ua cov khoom siv tiv thaiv kev hnav thiab lubricating. Cov khoom siv raw thawj zaug rau kev npaj cov graphite nthuav dav yog cov pa roj carbon siab flake graphite, thiab lwm yam tshuaj reagents xws li concentrated sulfuric acid (saum toj no 98%), hydrogen peroxide (saum toj no 28%), potassium permanganate thiab lwm yam tshuaj reagents kev lag luam siv. Cov kauj ruam dav dav ntawm kev npaj yog raws li nram no: ntawm qhov kub thiab txias, ntau qhov sib piv ntawm cov kua hydrogen peroxide, ntuj flake graphite thiab concentrated sulfuric acid raug ntxiv rau hauv cov txheej txheem sib txawv, thiab reacted rau ib lub sijhawm nyob rau hauv kev sib xyaw tas li, tom qab ntawd ntxuav kom tsis muaj zog, sib cais centrifugal, dehydration thiab nqus tsev ziab ntawm 60 ℃. Ntuj graphite hmoov muaj lubricity zoo thiab feem ntau siv ua cov khoom ntxiv rau hauv cov roj lubricating. Rau kev xa cov khoom siv corrosive, piston rings, sealing rings thiab bearings ua los ntawm cov hmoov graphite dag yog siv dav, tsis tas ntxiv cov roj lubricating thaum ua haujlwm. Ntuj graphite hmoov thiab polymer resin composites kuj tseem siv tau rau hauv cov teb saum toj no, tab sis kev tiv thaiv kev hnav tsis zoo li cov hmoov graphite dag.

3. Kev lag luam tshuaj lom neeg

Cov hmoov graphite cuav muaj cov yam ntxwv ntawm kev tiv taus corrosion, zoo thermal conductivity, qis permeability, thiab siv dav hauv kev lag luam tshuaj lom neeg los ua cov khoom siv hloov pauv cua sov, lub tank tshuaj tiv thaiv, lub tsev nqus dej, lim dej thiab lwm yam khoom siv. Cov hmoov graphite ntuj thiab cov khoom siv polymer resin sib xyaw kuj tseem siv tau rau hauv cov teb saum toj no, tab sis cov thermal conductivity, corrosion tsis zoo li cov hmoov graphite cuav.

Nrog rau kev txhim kho ntawm kev tshawb fawb txog thev naus laus zis, kev siv cov hmoov graphite cuav yog qhov tsis muaj qhov kawg. Tam sim no, kev siv cov graphite ntuj ua cov khoom siv raw los tsim cov khoom graphite cuav tuaj yeem suav tias yog ib txoj hauv kev tseem ceeb los nthuav dav daim ntawv thov ntawm cov graphite ntuj. Cov hmoov graphite ntuj tau siv ua cov khoom siv raw khoom hauv kev tsim cov hmoov graphite cuav, tab sis nws tsis txaus los tsim cov khoom graphite cuav nrog cov hmoov graphite ntuj ua cov khoom siv raw tseem ceeb. Txoj hauv kev zoo tshaj plaws los ua tiav lub hom phiaj no yog siv tag nrho cov qauv thiab cov yam ntxwv ntawm cov hmoov graphite ntuj, thiab tsim cov khoom graphite cuav nrog cov qauv tshwj xeeb, kev ua tau zoo thiab kev siv los ntawm cov thev naus laus zis, txoj kev thiab txoj kev tsim nyog.
