Raws li hnav-resistant lubricating khoom: graphite feem ntau yog siv los ua roj nplua nyeem hauv kev lag luam.Lubricating roj tsis tuaj yeem siv rau ntawm kev kub ceev, kub thiab kub siab, thaum graphite hnav-resistant khoom tuaj yeem ua haujlwm yam tsis muaj roj lubricating ntawm qhov siab zawv zawg ceev ntawm (I) 200 ~ 2000 ℃.Ntau yam khoom siv thauj khoom corrosive yog dav ua los ntawm cov khoom siv graphite rau hauv khob piston, sealing rings thiab bearings.Lawv tsis tas yuav ntxiv cov roj lubricating thaum ua haujlwm.Graphite emulsion kuj yog cov roj nplua nyeem zoo rau ntau cov hlau ua haujlwm (xov hlau kos duab thiab kos duab yeeb nkab).

lub hom phiaj
Kev lag luam folding
Graphite muaj kev ruaj ntseg zoo.Tshwj xeeb ua tiav graphite muaj cov yam ntxwv ntawm corrosion kuj, zoo thermal conductivity thiab tsis tshua muaj permeability.Nws yog dav siv los ua cov cua kub exchangers, cov tshuaj tiv thaiv tank, condensers, combustion towers, absorption towers, coolers, heaters, filters thiab twj tso kua mis.Nws yog dav siv hauv petrochemical, hydrometallurgy, acid thiab alkali ntau lawm, hluavtaws fiber ntau, ntawv thiab lwm yam kev lag luam, uas tuaj yeem txuag tau ntau cov ntaub ntawv hlau.

Siv los ua casting, foundry, molding thiab high-temperature metallurgical cov ntaub ntawv: Vim lub thermal expansion coefficient me me ntawm graphite thiab nws lub peev xwm los tiv thaiv cov kev hloov ntawm ceev ceev txias thiab kub, nws yuav siv tau raws li ib tug pwm rau iav.Tom qab siv cov graphite, cov hlau ferrous tuaj yeem tau txais qhov loj me me, qhov siab ntawm qhov tiav, thiab tuaj yeem siv yam tsis muaj kev ua haujlwm lossis ua haujlwm me ntsis, yog li txuag tau ntau cov hlau.Rau kev tsim cov cemented carbide thiab lwm cov hmoov metallurgy txheej txheem, graphite cov ntaub ntawv feem ntau yog siv los ua cov nkoj ceramic rau nias thiab sintering.Cov siv lead ua kev loj hlob crucible ntawm monocrystalline silicon, lub regional refining thawv, bracket clamp, induction rhaub, thiab lwm yam yog tag nrho cov ua los ntawm high-purity graphite.Tsis tas li ntawd, graphite kuj tseem siv tau los ua graphite rwb thaiv tsev phaj thiab lub hauv paus rau lub tshuab nqus tsev smelting, kub-kub tsis kam rauv tube, pas nrig, phaj, lattice thiab lwm yam khoom.

Graphite kuj tseem tuaj yeem tiv thaiv boiler scaling.Cov kev ntsuam xyuas hauv tsev qhia tau hais tias ntxiv qee qhov nyiaj ntawm graphite hmoov (kwv yees li 4 ~ 5 grams ib tuj dej) rau cov dej tuaj yeem tiv thaiv qhov kub hnyiab ntawm qhov chaw.Tsis tas li ntawd, graphite txheej ntawm hlau chimney, ru tsev, choj thiab kav dej tuaj yeem tiv thaiv corrosion thiab xeb.

Graphite tuaj yeem siv ua xaum xaum, xim thiab tus neeg saib xyuas polishing.Tom qab kev ua haujlwm tshwj xeeb, graphite tuaj yeem ua rau ntau yam ntaub ntawv tshwj xeeb rau cov tuam tsev muaj feem cuam tshuam.

Tsis tas li ntawd, graphite kuj yog tus neeg saib xyuas polishing thiab antirust tus neeg saib xyuas rau iav thiab ntawv hauv kev lag luam teeb, thiab cov khoom siv tsis tseem ceeb rau kev tsim cov xaum, number case, xim dub, number case, dag pob zeb diamond thiab pob zeb diamond.Nws yog lub zog txuag hluav taws xob zoo thiab cov khoom siv tiv thaiv ib puag ncig, uas tau siv los ua cov roj teeb tsheb hauv Tebchaws Meskas.Nrog rau txoj kev loj hlob ntawm niaj hnub science, technology thiab kev lag luam, daim ntawv thov teb ntawm graphite tseem nthuav.Nws tau dhau los ua ib qho tseem ceeb raw khoom rau cov khoom sib xyaw tshiab hauv kev ua haujlwm siab thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv lub tebchaws.

Folding lub teb chaws tiv thaiv
Siv nyob rau hauv kev lag luam atomic zog thiab kev lag luam tiv thaiv lub teb chaws: graphite muaj zoo neutron moderator siv nyob rau hauv atomic reactors, thiab uranium-graphite reactor yog ib hom ntawm atomic reactor uas yog dav siv.Cov khoom decelerating nyob rau hauv lub nuclear reactor siv raws li lub hwj chim yuav tsum muaj siab melting point, stability thiab corrosion kuj.Graphite tuaj yeem ua tau raws li qhov xav tau saum toj no.Lub purity ntawm graphite siv los ua lub atomic reactor yog siab heev, thiab cov ntsiab lus impurity yuav tsum tsis txhob ntau tshaj kaum ob ntawm PPMs.Tshwj xeeb, cov ntsiab lus boron yuav tsum tsawg dua 0.5PPM.Hauv kev lag luam tiv thaiv lub teb chaws, graphite kuj tseem siv los ua lub taub hau ntawm cov roj foob pob hluav taws, lub qhov ntswg ntawm lub foob pob hluav taws, qhov chaw ntawm cov khoom siv hauv chaw navigation, cov ntaub ntawv thermal rwb thaiv tsev thiab cov ntaub ntawv tiv thaiv hluav taws xob.
