Graphite hmoov yog lub kub nyob rau hauv cov teb muaj kev ua si, thiab nws ua lub luag haujlwm loj loj hauv ntau thaj teb. Ua ntej, feem ntau nws tau hais tias hmoov graphite yog qhov kev daws teeb meem zoo tshaj plaws los tiv thaiv kom xeb cov khoom siv, thiab ntau tus neeg siv khoom tsis paub vim li cas. Niaj hnub no, tus editor ntawm ib tug txiv hmab txiv ntoo graphite yuav piav qhia hauv nthuav dav vim li cas koj hais qhov no:
Qhov kev ua tau zoo ntawm graphite hmoov ua nws txoj kev daws zoo tshaj plaws los tiv thaiv cov khoom siv corrosion.
1. Tiv thaiv qee qhov kub thiab txias. Qhov ntsuas kub ntawm graphite hmoov yog nyob ntawm hom impregnating, xws li cov khoom siv Phenolegnating twg tuaj yeem txuas ntxiv, nws tuaj yeem tiv taus 350 ℃. Thaum phosphoric acid yog muab tso rau cov carbon thiab graphite, cov oxidation tiv thaiv carbon thiab graphite tuaj yeem hloov kho, thiab ua haujlwm tiag tiag kub yuav tau nce ntxiv.
2. Cov thermal thermal zoo heev. Graphite hmoov tseem muaj cov thermal zoo, uas yog siab tshaj qhov ntawm cov hlau uas tsis yog cov ntaub ntawv, kev ua thawj ntawm cov ntaub ntawv uas tsis yog. Lub thermal conductivity yog ob zaug uas cov pa roj carbon hlau thiab xya zaus uas hlau stainless. Yog li ntawd, nws yog tsim rau cov khoom siv cua sov.
3. Zoo heev corrosion tsis kam. Txhua yam carbon thiab graphite tau zoo corrosion tsis kam rau txhua qhov siab ntawm cov acid acid, piv txwv li fluorine-muaj me me. Daim ntawv thov kub yog 350 ℃ -400 ℃, uas yog, qhov kub ntawm cov pa roj carbon thiab graphite pib rau oxidize.
4. Cov nplaim tsis yooj yim rau cov qauv. Lub "affinity" ntawm graphite hmoov thiab feem ntau cov xov xwm yog heev me me, yog li av tsis yooj yim rau kev ua raws li saum npoo. Tshwj xeeb tshaj yog rau cov khoom siv hws thiab cov khoom siv siv lead ua.
Cov lus piav qhia saum toj no tuaj yeem ua rau koj nkag siab tob txog graphite hmoov. Qingdao Furuite Graphite Tshwj xeeb ua haujlwm tshwj xeeb hauv kev ua thiab ua cov hmoov graphite, flake graphite thiab lwm yam khoom. Koj zoo siab tos txais koj mus ntsib thiab coj peb lub hoobkas.
