Cov hluav taws xob graphite
1. Cov xwm txheej ua haujlwm: Cov txheej txheem sintering uas yuav tsum tau ua rau cov pob zeb diamond kub nias yog raws li nram no: Qhov kub yuav tsum ncav cuag 1000 ℃ ± 20 ℃, qhov siab tsim yuav tsum nyob nruab nrab ntawm 16 thiab 18 mpa, lub sijhawm tuav yuav tsum yog 4 txog 7 feeb, thiab ib puag ncig yuav tsum nyob rau hauv lub xeev tsis muaj lub tshuab nqus tsev. Hauv qab qhov xwm txheej ua haujlwm no, cov pwm graphite siv rau kev tsim thiab cua sov yuav tsum muaj qhov ceev ceev, lub zog kho tshuab txaus, siab resistivity, siab purity, muaj zog oxidation tsis kam thiab porosity tsawg, yog li kom ntseeg tau tias muaj kev ua tau zoo heev, qhov tseeb ntawm qhov ntev thiab lub neej ua haujlwm ntev ntawm cov pob zeb diamond kub nias.
2. Qhov xwm txheej tam sim no ntawm cov pwm graphite rau cov pob zeb diamond geological tho qhov hauv tsev txij li xyoo 1970, cov pwm graphite hauv tsev rau cov pob zeb diamond geological tho qhov feem ntau tau ua tiav nrog cov cib graphite purity siab. Los ntawm kev xaiv tas mus li, kev tshawb fawb thiab kev txhim kho, thiab kev txhim kho, lawv cov kev ua tau zoo tseem ceeb tuaj yeem ua tau raws li qhov xav tau ntawm cov txheej txheem sintering kub. Txawm li cas los xij, piv nrog qib siab thoob ntiaj teb tam sim no, tseem muaj qhov sib txawv loj heev. Qhov no xav tau kev siv zog tas mus li ntawm peb cov kws tshaj lij. Peb vam tias peb cov pob zeb diamond geological tho qhov kub yuav zoo dua thiab zoo dua. Qhov tseeb, hmoov graphite muaj ntau yam siv tau yooj yim hauv peb lub neej txhua hnub. Cia peb cia tus editor qhia koj txog lawv hnub no.
Hmoov graphite
Hmoov graphite feem ntau siv rau hauv kev lag luam, tab sis nws kuj muaj kev siv hauv lub neej txhua hnub. Nov yog kev qhia luv luv txog qee qhov kev siv hmoov graphite hauv lub neej txhua hnub. Hmoov graphite yog cov roj nplua nyeem ntuj. Nws muaj cov khoom siv zoo rau nws tus kheej, thiab thaum ua tiav rau hauv cov hmoov graphite zoo heev, nws cov khoom siv roj nplua nyeem zoo dua. Yog li, nws tuaj yeem ua rau cov hmoov graphite roj nplua nyeem rau kev ua kom lubrication thiab lwm yam.
Niaj hnub no siv cov roj nplaum graphite hmoov qhov twg hauv lub neej txhua hnub? Nws yog lub xauv qhov rooj uas siv ntau tshaj plaws.
Cov hluav taws xob graphite
Lub xauv tsheb tau qhib lawm. Vim tias lub xauv qhov rooj thiab lwm yam khoom siv tau siv ntev lawm, lub plawv xauv yuav ua rau huab cua thiab lwm yam, ua rau xeb. Qhov no tuaj yeem ua rau muaj teeb meem hauv kev tig tus yuam sij, ntsaws thiab tshem tawm, thiab qhib. Kuv ntseeg tias ntau tus neeg tau ntsib cov xwm txheej zoo li no. Niaj hnub no, ntau lub koom haum qhib xauv thiab cov neeg ua haujlwm saib xyuas xauv pom zoo kom siv cov roj nplua nyeem graphite rau lub plawv xauv. Cov roj nplua nyeem graphite no yog tsim los daws cov teeb meem xws li nyuaj rau tig lub plawv xauv, tiv thaiv nws kom tsis txhob raug ntswj thaum lub sijhawm tig tus yuam sij, uas thaum kawg yuav ua rau yuav tsum tau rhuav tshem lossis hloov lub xauv, ua rau muaj teeb meem loj. Niaj hnub no, ntau tsev neeg muaj cov roj nplua nyeem graphite hauv tsev los tswj lub plawv xauv, tab sis ntau tus neeg tsis muaj. Qhov no yog qhov hu ua kev siv hmoov graphite hauv lub neej txhua hnub.
Cov roj nplua nyeem graphite hauv lub xauv qhov tseem ceeb muaj cov hmoov graphite tshwj xeeb rau kev ua kom lubrication. Tab sis nws tsis muaj teeb meem yog tias koj tsis muaj nws. Koj tuaj yeem nrhiav ib tug cwj mem thiab siv riam me me los khawb qee cov hmoov txhuas zoo heev. Vim tias niaj hnub no cov hlau txhuas muaj cov hmoov graphite, thiab cov hmoov graphite yog cov roj nplua nyeem tag nrho. Qhov tsis zoo yog tias nws siv sijhawm ntau thiab ua teeb meem, thiab qhov huv ntawm cov hmoov graphite tsis huv thiab nws muaj lwm yam khoom. Cov nyhuv ua kom lubrication tsis zoo li cov hmoov graphite hauv lub xauv qhov tseem ceeb, thiab nws kuj ua teeb meem heev rau kev ua haujlwm. Nws tsis yooj yim li cov hmoov graphite hauv lub xauv qhov tseem ceeb.
Cov khoom tseem ceeb ntawm lub tuam txhab yog: Graphite, cov khoom graphite, flake graphite, hmoov graphite, ntawv graphite, colloidal graphite, conductive graphite, medium-carbon graphite, high-carbon graphite, flake graphite, high-purity graphite, tshwj xeeb graphite rau hmoov metallurgy, tshwj xeeb graphite hmoov rau carbon txhuam, tshwj xeeb graphite hmoov rau vanadium-nitrogen alloys, flake graphite rau kev sib txhuam cov ntaub ntawv, nthuav dav graphite, tshwj xeeb graphite hmoov rau coatings, ntau yam specifications ntawm graphite hmoov rau cwj mem leads, forging graphite emulsion Muaj ze li ntawm 100 ntau yam thiab ntau tshaj 200 specifications ntawm graphite ntawv, graphite blocks, dag graphite thiab graphite khoom rau sealing. Tam sim no peb tau tsim kom muaj kev sib raug zoo ntev nrog ntau tshaj 200 lub tsev hauv tsev thiab txawv teb chaws thiab tau txais kev qhuas los ntawm feem ntau ntawm cov neeg siv.
