Graphite siv tau ua tus cwj mem, xim, tus neeg sawv cev polishing, tom qab ua tiav tshwj xeeb, tuaj yeem ua los ntawm ntau yam khoom siv tshwj xeeb, siv rau hauv cov lag luam cuam tshuam. Yog li kev siv tshwj xeeb ntawm graphite hmoov yog dab tsi? Nov yog kev tshuaj xyuas rau koj.
Cov hmoov graphite muaj kev ruaj khov tshuaj zoo. Cov pob zeb toner tom qab ua tiav tshwj xeeb, muaj cov yam ntxwv ntawm kev tiv thaiv corrosion zoo, thermal conductivity zoo, permeability qis, dav siv rau hauv kev tsim cov cua sov exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, lim, twj tso kua mis. Dav siv rau hauv petrochemical, hydrometallurgy, acid thiab alkali tsim, synthetic fiber, ntawv thiab lwm yam lag luam, tuaj yeem txuag tau ntau cov khoom siv hlau.
Rau kev casting, txhuas casting, molding thiab cov khoom siv hlau kub siab: vim yog graphite thermal expansion coefficient me me, thiab tuaj yeem tshwm sim thermal cuam tshuam kev hloov pauv, tuaj yeem siv ua iav pwm, siv graphite dub hlau casting qhov loj me precision, du nto thiab siab yield, tsis muaj kev ua tiav lossis me ntsis kev ua tiav tuaj yeem siv, yog li txuag tau ntau ntawm cov hlau. Kev tsim cov cement carbide hmoov metallurgy txheej txheem, feem ntau yog ua los ntawm cov khoom siv graphite, sintered nrog porcelain vessels. Crystal loj hlob furnaces, xws li monocrystalline silicon, cheeb tsam refining vessels, bracket fixtures, induction heaters, thiab lwm yam yog ua los ntawm high purity graphite. Tsis tas li ntawd, graphite kuj tseem siv tau ua lub tshuab nqus tsev smelting graphite rwb thaiv tsev board thiab lub hauv paus, kub kub resistant cub tawg raj, bar, phaj, lattice thiab lwm yam khoom.
Graphite kuj tseem tuaj yeem tiv thaiv kev nce hauv boiler, kev sim ua haujlwm qhia tau tias kev ntxiv qee yam hmoov graphite rau hauv dej (kwv yees li 4 ~ 5 grams ib tuj dej) tuaj yeem tiv thaiv kev nce hauv qhov chaw ntawm boiler. Tsis tas li ntawd, graphite tuaj yeem siv rau hauv cov qhov cub hlau, ru tsev, Choj thiab cov kav dej.
Tsis tas li ntawd xwb, graphite los yog iav thiab ntawv siv rau hauv kev lag luam teeb pom kev zoo los ua kom cov xim tsis xeb thiab tiv thaiv xeb, yog cov khoom siv raw uas siv los ua cov cwj mem, kua mem, xim dub, kua mem thiab pob zeb diamond, pob zeb diamond tseem ceeb heev. Nws yog cov khoom siv txuag hluav taws xob zoo heev thiab tiv thaiv ib puag ncig, Tebchaws Meskas tau siv nws ua lub roj teeb tsheb. Nrog rau kev txhim kho ntawm kev tshawb fawb niaj hnub thiab kev lag luam, kev siv graphite txuas ntxiv mus, tau dhau los ua cov khoom siv raw tseem ceeb hauv kev lag luam high-tech ntawm cov khoom sib xyaw tshiab, thiab nws yog ib qho tseem ceeb hauv kev lag luam hauv tebchaws.
Siv rau hauv kev lag luam atomic zog thiab kev lag luam tiv thaiv lub teb chaws: graphite hmoov muaj neutron positron zoo siv rau hauv atomic reactors, uranium graphite reactor siv ntau dua hauv atomic reactor. Raws li lub zog siv ua cov khoom siv deceleration rau nuclear reactor, nws yuav tsum muaj qhov siab melting point, stability thiab corrosion tsis kam, thiab graphite hmoov tuaj yeem ua tau raws li cov kev cai saum toj no. Graphite siv rau hauv atomic reactors yog ntshiab heev uas impurities yuav tsum tsis pub tshaj kaum tawm ntawm ib lab. Tshwj xeeb, cov ntsiab lus ntawm polone yuav tsum tsawg dua 0.5PPM. Hauv kev lag luam tiv thaiv, graphite hmoov kuj tseem siv los ua nozzles rau rockets roj khov, lub qhov ntswg cones rau missiles, qhov chaw rau cov khoom siv navigation qhov chaw, rwb thaiv tsev kub, thiab cov ntaub ntawv tiv thaiv hluav taws xob.
