AGRM coj ntau xyoo kev txawj ntse nyob rau hauv graphite cov khoom siv ntau lawm, featuring advanced graphite hmoov ua technology thiab ib tug mob siab rau ua rhiav. Peb muab cov hmoov graphite zoo nyob rau hauv ntau qhov ntau thiab tsawg, suav nrog kev ua siab dawb huv, tus qauv, thiab cov kev xaiv zoo tshaj plaws, nrog rau lub cev thiab tshuaj lom neeg uas muaj zog tshaj li cov qauv kev lag luam.
Peb cov graphite hmoov yog dawb ntawm impurities, ua tau raws li cov neeg siv khoom xav tau rau graphite solutes. Txij li xyoo 2012, peb tau ua tus xa khoom tshwj xeeb ntawm graphite hmoov rau Tuam Tshoj cov chaw tsim khoom loj tshaj plaws, xa ntau tshaj 8,000 tons ib xyoos ib zaug.
Graphite hmoov, cov ntxhia hmoov feem ntau yog tsim los ntawm cov pa roj carbon, yog mos nrog cov xim dub-grey thiab greasy zoo nkauj uas tuaj yeem kos daim ntawv. Nws hardness ranges ntawm 1 mus rau 2, nce mus rau 3 mus rau 5 vertically nrog siab impurity theem. Nrog lub ntiajteb txawj nqus ntawm 1.9 txog 2.3, nws boasts lub melting point saum toj no 3000 degree nyob rau hauv tsis muaj oxygen tej yam kev mob, ua rau nws yog ib qho ntawm feem ntau tshav kub-resistant minerals. Graphite hmoov yog tshuaj ruaj khov nyob rau hauv chav tsev kub, insoluble nyob rau hauv dej, dilute acids, dilute alkalis, thiab organic solvents. Nws qhov kub thiab txias tsis kam thiab hluav taws xob conductivity ua rau nws zoo tagnrho rau siv nyob rau hauv cov ntaub ntawv refractory, cov ntaub ntawv conductive, thiab hnav-resistant lubricants.

cov khoom siv ntawm graphite hmoov
Graphite hmoov yog rhiab heev rau nws ib puag ncig, ua rau nws cov resistivity sib txawv. Raws li ib qho ntawm cov khoom siv zoo tshaj plaws uas tsis yog xim hlau, nws cov kev hloov pauv raws li qhov coarseness thiab ib puag ncig. Graphite tus qauv tshwj xeeb pub rau nws ntau yam tseem ceeb:
High-Temperature Resistance:Graphite muaj qhov melting point ntawm 3850 ± 50 degree thiab qhov kub ntawm 4250 degree. Txawm tias nyob rau hauv huab cua kub, nws muaj kev poob phaus tsawg thiab muaj cov thermal expansion coefficient tsawg. Nws lub zog ob npaug ntawm 2000 degree.
Hluav taws xob thiab Thermal conductivity:Graphite ua hluav taws xob ntawm qib 100 npaug ntau dua li lwm cov khoom siv hlau tsis yog hlau, thiab nws cov thermal conductivity tshaj cov hlau xws li hlau thiab hlau. Txawm li cas los xij, nws cov thermal conductivity txo qis nrog qhov kub thiab txias, nws thiaj li ua rau nws lub rwb thaiv tsev ntawm qhov kub siab heev.
Lubricity:Lub lubricating cuab yeej ntawm graphite nyob ntawm flake loj-qhov loj ntawm cov flakes, qhov zoo dua lub lubricaity vim muaj kev sib txhuam coefficient.
Chemical Stability:Graphite yog tshuaj ruaj khov nyob rau hauv chav tsev kub, tiv thaiv corrosion los ntawm acids, alkalis, thiab organic solvents.
Plasticity:Graphite yog qhov yooj yim heev thiab tuaj yeem tsim ua cov ntawv nyias.
Thermal Shock Resistance:Graphite tuaj yeem tiv taus qhov kub thiab txias hloov ntawm chav tsev kub yam tsis muaj kev puas tsuaj, tswj nws qhov ntim thiab kev ua haujlwm zoo.
kev siv ntawm graphite hmoov
Cov khoom siv refractory:Graphite thiab nws cov derivatives paub txog lawv qhov tshwj xeeb ntawm qhov kub thiab txias, ua rau lawv zoo tagnrho rau kev siv hauv kev lag luam metallurgical. Lawv feem ntau yog siv los tsim cov graphite crucibles thiab ua cov tshuaj tiv thaiv rau steel ingots thiab hauv ob sab phlu hauv metallurgical furnaces thaum steelmaking.
Cov khoom siv conductive:Hauv kev lag luam hluav taws xob, graphite yog siv los tsim ntau yam khoom siv hluav taws xob, suav nrog electrodes, txhuam, carbon rods, carbon tubes, zoo electrodes rau mercury rectifiers, graphite gaskets, xov tooj, thiab coatings rau TV duab raj.
Hnav-Resistant Lubricating Materials:Graphite lub lubricating zog muaj nuj nqis heev nyob rau hauv kev lag luam machinery, tshwj xeeb tshaj yog nyob rau hauv tej yam kev mob uas cov pa roj lubricating tsis, xws li high-speed, high-temperature, thiab high-pressure ib puag ncig. Graphite-raws li hnav-tiv taus cov ntaub ntawv tuaj yeem ua haujlwm yam tsis muaj roj lubricating, txawm tias qhov zawv zawg nrawm hauv qhov kub ntawm 200 degree txog 2000 degree. Tsis tas li ntawd, cov ntaub ntawv graphite tau siv dav hauv cov cuab yeej thauj khoom corrosive media, uas lawv tau tsim rau hauv piston khob, seals, thiab bearings, tshem tawm qhov xav tau ntawm cov roj lubricating. Graphite emulsion kuj tseem ua cov roj nplua nyeem zoo hauv cov ntawv thov hlau xws li hlau thiab raj kos duab.
