Graphite board yog ib qho tseem ceeb ntawm cov khoom siv dav siv hauv cov cua kub kub, cov khoom siv kho cua sov thiab ntau yam kev lag luam. Nws zoo heev thermal conductivity, kub tsis kam thiab siab zog ua graphite board ib tug zoo tagnrho refractory khoom. Txawm li cas los xij, kev ua tau zoo ntawm graphite phaj yog cuam tshuam los ntawm nws cov txheej txheem kev npaj thiab cov khoom siv raw, yog li ntawd, nws yog ib qho tseem ceeb heev los xaiv cov khoom siv graphite kom zoo los xyuas kom meej tias kev ua haujlwm zoo thiab kev pabcuam lub neej ntawm cov khoom siv.
Ua ntej, cov khoom siv raw ntawm graphite board
Cov ntaub ntawv raw ntawm graphite board feem ntau suav nrog ntuj flake graphite, dag graphite thiab sib xyaw graphite. Ntawm lawv, ntuj flake graphite muaj siab purity thiab kub ua hauj, tab sis yog susceptible impurities, dag graphite muaj zoo thermal conductivity thiab corrosion kuj, tab sis siab nqi, thiab sib tov graphite combines qhov zoo ntawm ntuj flake graphite thiab dag graphite, thiab muaj. tus nqi siab ua haujlwm.
Qhov thib ob, cov txheej txheem kev npaj ntawm graphite phaj
Cov txheej txheem kev npaj ntawm graphite phaj feem ntau suav nrog batching, molding, sintering thiab txias. Ntawm lawv, batching yog ib qho ntawm cov kev sib txuas tseem ceeb, uas cuam tshuam ncaj qha rau kev ua haujlwm ntawm graphite daim hlau. Nyob rau hauv cov txheej txheem batching, nws yog ib qho tsim nyog yuav tsum tau ntxiv qhov tsim nyog ntawm binders, lubricants thiab lwm yam khoom siv los txhim kho lub formability thiab lub zog ntawm graphite phaj. Kev tsim cov txheej txheem xws li calendering lossis extrusion molding feem ntau yog siv kom tau cov nplooj ntawv graphite ntawm cov lus qhia txawv thiab cov duab. Cov sintering thiab txias txuas ncaj qha txiav txim siab lub cev thiab tshuaj lom neeg ntawm graphite phaj.
Thib peb, lub hauv paus ntsiab lus ntawm kev xaiv cov khoom siv graphite phaj
Kev kub siab tiv thaiv: Graphite nplooj ntawv yuav tsum tau ua haujlwm nyob rau hauv qhov chaw kub kub, yog li cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias yuav tsum tau xaiv. Ntuj flake graphite thiab sib xyaw graphite muaj qhov kub thiab txias tsis kam, thaum cov khoom siv graphite muaj qhov kub tsis zoo.
Thermal conductivity: Graphite daim hlau yuav tsum muaj thermal conductivity zoo heev kom qhov kub thiab txias hauv qhov cub kom ruaj khov. Ntuj flake graphite thiab sib xyaw graphite muaj cov thermal conductivity zoo, thaum cov khoom graphite muaj cov thermal conductivity tsis zoo.
Mechanical zog: Graphite phaj yuav tsum muaj lub zog txhua yam los tiv thaiv qhov cuam tshuam thiab hnav ntawm cov ntaub ntawv hauv qhov cub ntawm cov khoom siv. Ntuj flake graphite thiab hybrid graphite muaj lub zog txhua yam, thaum cov khoom siv graphite muaj kev sib piv qis dua txhua yam.
Economy: Ntawm qhov chaw ua tau raws li qhov yuav tsum tau siv, cov khoom siv nrog tus nqi tsim nyog thiab kev pab lub neej ntev yuav tsum nyiam. Tus nqi ntawm ntuj flake graphite yog siab dua, tab sis tus nqi ntawm cov khoom graphite thiab hybrid graphite yog tus nqi qis.
Machinability: Graphite daim hlau yuav tsum tau ua tiav raws li qhov xav tau ntawm kev ua haujlwm, yog li nws yog qhov tsim nyog los xaiv cov khoom siv uas yooj yim rau kev ua haujlwm. Ntuj flake graphite thiab sib xyaw graphite muaj kev ua tau zoo dua, thaum cov khoom siv graphite muaj kev ua haujlwm tsis zoo.
