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

Hmoov graphite muaj ntau yam khoom zoo heev, yog li nws siv dav hauv metallurgy, machinery, hluav taws xob, tshuaj lom neeg, textile, kev tiv thaiv lub teb chaws thiab lwm yam kev lag luam. Cov teb thov ntawm cov hmoov graphite ntuj thiab cov hmoov graphite dag muaj ob qho tib si sib tshooj thiab qhov sib txawv. Cov kws kho graphite Furuite hauv qab no qhia txog 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 magnesia-carbon cib thiab txhuas-carbon cib vim nws zoo tiv taus oxidation. Hmoov graphite dag siv tau ua electrode ua hlau, tab sis cov electrodes ua los ntawm hmoov graphite ntuj nyuaj rau siv hauv cov cub hluav taws xob ua hlau nrog cov xwm txheej ua haujlwm hnyav.

2. Kev lag luam tshuab

Hauv kev lag luam tshuab, cov ntaub ntawv graphite feem ntau yog siv los ua cov khoom siv uas tsis yooj yim hnav thiab ua kom lubricating. Cov khoom siv raw thawj zaug rau kev npaj cov graphite nthuav dav yog cov roj carbon siab, 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 yog txhua yam tshuaj reagents qib kev lag luam. 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, natural flake graphite thiab concentrated sulfuric acid raug ntxiv rau hauv cov txheej txheem sib txawv, reacted rau ib lub sijhawm ntawm lub sijhawm nyob rau hauv kev sib xyaw tas li, tom qab ntawd ntxuav nrog dej kom txog thaum tsis muaj teeb meem, thiab centrifuged. Tom qab dehydration, nws tau nqus tsev qhuav ntawm 60 ° C. Cov hmoov graphite ntuj muaj lubricity zoo thiab feem ntau yog siv ua cov khoom ntxiv rau cov roj lubricating. Cov khoom siv rau kev xa cov khoom siv corrosive siv dav dav piston rings, sealing rings thiab bearings ua los ntawm cov hmoov graphite dag, thiab tsis tas yuav ntxiv cov roj lubricating thaum lub sijhawm ua haujlwm. Cov hmoov graphite ntuj thiab cov ntaub ntawv polymer resin composite kuj tseem siv tau rau hauv cov teb saum toj no, tab sis qhov kev tiv thaiv 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 thiab qis permeability. Nws yog dav siv hauv kev lag luam tshuaj lom neeg los ua cov cua sov sib pauv, cov tank tshuaj tiv thaiv, cov pej thuam nqus, cov 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 thiab corrosion tsis zoo li cov hmoov graphite cuav.

Nrog rau kev txhim kho tas mus li ntawm kev tshawb fawb txog thev naus laus zis, kev siv cov hmoov graphite cuav yog qhov tsis muaj qhov ntsuas tau. Tam sim no, kev tsim cov khoom siv graphite cuav nrog graphite ntuj ua cov khoom siv raw yog ib txoj hauv kev tseem ceeb los nthuav dav daim ntawv thov ntawm graphite ntuj. Hmoov graphite ntuj ua cov khoom siv raw khoom pab tau siv rau hauv kev tsim cov hmoov graphite cuav, tab sis kev tsim cov khoom siv graphite cuav nrog hmoov graphite ntuj ua cov khoom siv raw tseem ceeb tsis txaus. Nws yog txoj hauv kev zoo tshaj plaws los ua tiav lub hom phiaj no los ntawm kev nkag siab tag nrho thiab siv cov qauv thiab cov yam ntxwv ntawm cov hmoov graphite ntuj, thiab txais yuav cov txheej txheem, txoj kev thiab cov txheej txheem tsim nyog los tsim cov khoom siv graphite cuav nrog cov qauv tshwj xeeb, cov khoom thiab kev siv.
