Yuav Tshaj Li Cas Sib Txawv Ntawm Qhov Zoo Ntawm Cov Laj Lim Thiab Cov Tsis Zoo Ntawm Cov Neej Graphite?
- Oct 26, 2017 -

Yuav ua li cas kom paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo ntawm Expandable Graphite?
1. Lub zog ntawm cov ntaub ntawv
Lub flexural zog ntawm cov ntaub ntawv yog ib qho kev tsis ncaj nraim ntawm kev siv ntawm cov ntaub ntawv, uas qhia cov nyuaj theem ntawm tus qauv ntawm cov ntaub ntawv. Siab zog ntawm cov ntaub ntawv, qhov kev poob ntawm txoj haujlwm yog zoo dua, ntawm lub siab tshaj plaws electrode, sim xaiv lub zog zoo ntawm cov ntaub ntawv. Piv txwv li: TTK-4 tuaj yeem ua tau raws li txoj cai ntawm kev siv hluav taws xob hauv nruab nrab, tiam sis qee qhov tshwj xeeb yuav tsum tau muaj cov pwm hauv tshuab hluav taws xob, koj tuaj yeem siv tib qhov loj me, tab sis lub zog ntawm cov ntaub ntawv TTK-5 me ntsis.
2. Cov ntaub ntawv ntawm ntug dej
Hauv txoj kev pom ntawm qhov pom ntawm Graphic Expandable Graphite, Expandable Graphite feem ntau xav tias yuav tsum muaj ntaub ntawv tseem ceeb. Tab sis qhov tseeb cov ntaub ntawv xeem thiab kev siv ntawm qhov teeb meem no qhia tau hais tias lub hardness ntawm Expandable Graphite tshaj cov ntaub ntawv hlau. Hauv kev nthuav dav Graphite tshwj xeeb, qhov kev sojntsuam dav dav feem ntau yog qhov nqes ntawm kev ntsuas ntawm ntug dej, cov qauv kev xeem thiab cov qauv kuaj hlau yog txawv. Vim yog cov qauv ntawm cov txuj ci loj dua, nws muaj kev txiav txim siab zoo tshaj plaws nyob rau hauv cov txheej txheem txiav. Lub zog quab yuam tsuas yog li ntawm 1/3 ntawm cov khoom siv tooj liab, thiab qhov zoo li tom qab ua haujlwm yog ib qho yooj yim uas ua haujlwm.
Tab sis vim nws txoj kev kub siab, hauv kev txiav, lub cuab tam ntawm qhov kev poob yuav loj me dua qhov kev txiav hlau. Nyob rau tib lub sijhawm, qhov nyuaj ntawm cov ntaub ntawv hauv qhov kev tswj tsis tau yog qhov zoo dua. Nyob rau hauv peb cov ntaub ntawv EDM, kev siv cov ntaub ntawv ntxiv rau tib qho loj ntawm ob cov ntaub ntawv muaj rau xaiv los ntawm, me ntsis dua hardness, me ntsis qis zog kom tau raws li qhov kev xav tau ntawm tus neeg thov. Xws li: cov khoom sib npaug particle loj 5μm, ISO-63 thiab TTK-50; cov khoom tshwj xeeb qhov loj ntawm 4μm cov ntaub ntawv, TTK-4 thiab TTK-5; cov hluav taws kub hnyav li 2μm, TTK-8 thiab TTK -9. Qhov thib ob yog xav txog ntau yam ntawm cov neeg muas zaub ntawm kev tawm thiab kev coj ua ntawm kev siv lub tshuab.
3. Qhov nruab nrab ntawm qhov nruab nrab ntawm cov ntaub ntawv
Qhov ncaj nruab nrab inch ntawm cov ntaub ntawv tsis pub cuam tshuam cov paug ntawm cov ntaub ntawv. Qhov me me qhov tsis meej ntawm cov ntaub ntawv, qhov nruab nrab ntau tshaj qhov tawm ntawm cov ntaub ntawv, qhov ntau resolute lub tawm, qhov zoo dua qhov zoo tsos.
Nyob rau hauv kev lag luam metallurgical, nplai ntuj scalable graphite vim zoo oxidation kuj yuav siv tau los ntawm kev siv magnesium carbon cib thiab txhuas carbon cib thiab lwm cov ntaub ntawv refractory. Ntuj Extendable Graphite siv tau ua ib lub cav hlau, thiab hluav taws xob extrudable graphite electrode yog qhov nyuaj rau kev siv ntau dua xav ua hlau ua hluav taws xob.
Nyob rau hauv kev lag luam kev lag luam, Cov Ntaub Ntawv Tshaj Tawm los ntawm Kev Siv Graphite yog siv los hnav thiab cov ntaub ntawv sib luag. Kev ntsuas ntawm lub cev Txuj ci zoo ib qho zoo, feem ntau yog siv los ua ib tus roj roj ntxiv. Kev siv cov cuab yeej corrosive media, feem ntau siv los ntawm cov khoom ntws nthuav dav ntawm piston rings, cov ntsaws ruaj ruaj thiab cov menyuam, cov nyiaj tsis muaj kev koom nrog hauv cov roj. Kev nthuav dav ntawm ntuj thiab cov duab polymer resin cov ntaub ntawv kuj siv tau rau cov kab saum toj no, tab sis txoj kev ua haujlwm hnyav li natural expansive graphite.
Hauv kev lag luam cov tshuaj, lub ntuj nthuav dav nrawm nrog corrosion resistance, zoo thermal conductivity, permeability thiab lwm yam ntxwv ntawm thawj. Nyob rau hauv kev lag luam hauv tshuaj lom neeg feem ntau yog siv los ua cov khoom siv hluav taws xob, cov tshuaj tiv thaiv, kev yees, cov ntxaij lim dej thiab lwm cov khoom siv. Kev nthuav dav ntawm Natural thiab Extensable Polymer reag cov ntaub ntawv kuj tseem siv tau rau cov kab saum toj saud, tiam sis cov thermal conductivity, kev tiv thaiv kev qia hluav taws xob raws li ntuj nthuav dav nrawm.
Pyrolytic carbon thiab pyrolytic Expandable Graphite muaj kev kub siab thiab kev tiv thaiv corrosion, yog li nyob rau hauv expansion ntawm graphite cov khoom ntim ntawm cov tshuaj vapor deposition txoj kev los tso ib qhov nqi ntawm pyrolytic carbon los yog pyrolytic expansive graphite, yuav ua rau kom cov expansion Graphite khoom oxidation tsis kam, Txawm li cas los xij, feem ntau nyuaj shortcomings ntawm ntshiab pyrolytic carbon txheej yog anisotropic, yooj yim los mus peeling nyob rau hauv kev xyaum.
