Daim ntawv thov cov hmoov graphite

Graphite tuaj yeem siv ua cov xaum xaum, xim, polishing tus neeg sawv cev, tom qab kev ua haujlwm tshwj xeeb, tuaj yeem ua los ntawm ntau yam khoom tshwj xeeb, siv hauv kev lag luam cuam tshuam nrog. Yog li dab tsi yog qhov siv tshwj xeeb ntawm graphite hmoov? Nov yog kev tshuaj xyuas rau koj.

Graphite hmoov muaj tshuaj zoo ruaj khov. Pob zeb toner tom qab ua tiav tshwj xeeb, muaj cov yam ntxwv ntawm kev tiv thaiv corrosion zoo, thermal conductivity, tsis muaj permeability, dav siv hauv kev tsim cov cua sov hloov pauv, cov tshuaj tiv thaiv lub tank, condenser, ntauwd sib txuas, ntauwd nqus, txias dua, rhaub, lim, twj tso kua mis. Siv dav hauv petrochemical, hydrometallurgy, kua qaub thiab alkali ntau lawm, hluavtaws hluavtaws, ntawv thiab lwm yam lag luam, tuaj yeem txuag tau ntau yam khoom siv hlau.

Rau casting, aluminium casting, molding thiab cov khoom siv hlau kub: vim tias graphite thermal nthuav coefficient yog me me, thiab tuaj yeem tshwm sim qhov cuam tshuam kev hloov pauv kub, tuaj yeem siv ua iav pwm, siv graphite dub hlau casting loj qhov tseeb, du nto thiab siab tawm los, tsis ua tiav lossis ua haujlwm me ntsis tuaj yeem siv tau, thiaj li txuag tau hlau ntau. Kev tsim cov cement carbide hmoov txheej txheem hlau, feem ntau yog ua los ntawm cov khoom siv graphite, sintered nrog cov hlab ntsha. Cov khoom siv hluav taws xob loj loj, xws li monocrystalline silicon, cov khoom siv hauv cheeb tsam ua kom zoo nkauj, cov khoom sib dhos, cov cua sov induction, thiab lwm yam yog ua tiav los ntawm cov khoom siv siab purity. Ib qho ntxiv, graphite kuj tseem tuaj yeem siv ua lub tshuab nqus tsev ntxhua khaub ncaws graphite rwb thaiv tsev thiab lub hauv paus, qhov kub thiab txias tiv taus cua sov raj, bar, phaj, lattice thiab lwm yam khoom siv.

Graphite tseem tuaj yeem tiv thaiv lub rhaub dej kub, cuam tshuam txog kev ntsuas ntsuas pom tias ntxiv qee qhov graphite hmoov hauv dej (kwv yees li 4 ~ 5 grams ib tuj dej) tuaj yeem tiv thaiv lub rhaub dej kub nplai. Ntxiv rau, graphite tuaj yeem siv rau hauv cov kav hlau, lub ru tsev, Cov txuas hniav thiab cov kav dej.

Ib qho ntxiv, graphite lossis iav thiab ntawv hauv lub teeb kev lag luam txhuam thiab xeb inhibitor, yog kev tsim cov xaum xim, tus lej, xim dub, tus lej thiab cov khoom siv hluavtaws pob zeb diamond, cov khoom siv raw yog qhov tseem ceeb. Nws yog lub zog txuag hluav taws xob zoo heev thiab cov khoom siv tiv thaiv ib puag ncig, Tebchaws Asmeskas tau siv nws ua roj teeb tsheb. Nrog kev txhim kho kev tshawb fawb thiab thev naus laus zis niaj hnub no thiab kev lag luam, daim ntawv thov graphite txuas ntxiv nthuav dav, tau dhau los ua cov khoom siv tseem ceeb hauv cov thev naus laus zis thev naus laus zis tshiab ntawm cov khoom sib xyaw tshiab, ua haujlwm tseem ceeb hauv kev lag luam hauv tebchaws.

Siv hauv kev lag luam atomic zog thiab kev tiv thaiv kev lag luam hauv tebchaws: cov graphite hmoov muaj cov neutron positron zoo siv hauv cov tshuaj tiv thaiv atomic, uranium graphite reactor tau siv ntau dua hauv cov tshuaj tiv thaiv atomic. Raws li lub zog siv los ua cov khoom siv nrawm rau nuclear reactor, nws yuav tsum muaj cov ntsiab lus melting siab, ruaj khov thiab tiv taus corrosion, thiab graphite hmoov tuaj yeem ua tau raws li qhov xav tau saum toj no. Graphite siv hauv cov tshuaj tiv thaiv atomic yog qhov huv heev uas cov khoom tsis huv yuav tsum tsis pub ntau tshaj kaum feem ntawm ib lab. Tshwj xeeb, cov ntsiab lus ntawm polone yuav tsum tsawg dua 0.5PPM. Hauv kev tiv thaiv kev lag luam, cov hmoov graphite kuj tseem siv los ua lub taub hau rau cov foob pob hluav taws ruaj khov, lub qhov ntswg cones rau cov cuaj luaj, ntu rau cov khoom siv mus rau qhov chaw, rwb thaiv tsev cua sov, thiab cov khoom tiv thaiv hluav taws xob.
