Graphite daim ntawv yog dav siv hauv kev lag luam cua sov, cov khoom siv tshuaj lom neeg siv tshuaj, thiab lwm thaj chaw ua haujlwm siv tau zoo, corrosion tsis kam, thiab hluav taws xob cuam tshuam. Txawm li cas los xij, kev siv tsis raug cai tuaj yeem ua rau txo qis kev ua haujlwm thiab lub neej pabcuam luv. Hauv qab no yog qee cov lus qhia tswv yim los pab koj kom zoo thiab siv cov ntawv graphite.
1. Txom Nyem thiab kho
Thaum txhim kho graphite cov ntawv, xyuas kom lawv haum ntxig tiv thaiv kev tiv toj saum npoo uas yuav ua rau muaj kev xav txog hauv ib cheeb tsam lossis kev ntxhov siab. Siv tshwj xeeb clamps lossis siab - kub ua kom tau txais lawv. Zam kev cuam tshuam ncaj qha lossis khawb cov npoo nrog cov khoom tawv kom tsis txhob ua rau muaj cov qauv tsim qauv graphite. Ua ntej kev teeb tsa, soj ntsuam cov ntawv kom tawg lossis tsis meej los ua kom nws muaj kev ncaj ncees.
2. Tswj kev ua haujlwm kub
Thaum graphite cov ntawv qhia muaj cov cua sov muaj zog, siv ntau dhau ntawm kev kub ntxhov heev tuaj yeem nrawm oxidation thiab hnav. Feem ntau nws pom zoo kom siv lawv nyob rau hauv qhov ntsuas kub ntau (feem ntau tsis muaj ntau tshaj 3000 degree) thiab zam kev ua kom txias lossis cua sov tiv thaiv kev ntxhov siab. Nyob rau hauv high - sov ib puag ncig, xav txog qhia cov roj inert (xws li argon) kom txo qis kev pheej hmoo ntawm oxidation.
3. Zam kev ua yeeb yam corrosion
Txawm hais tias graphite muaj cov zoo corrosion tsis kam, nws tseem tuaj yeem puas los ntawm cov muaj zog acids, hauv paus muaj zog, lossis qee yam ntawm aluminium (tooj liab). Xaiv cov khoom siv graphite tsim nyog raws cov kev ua haujlwm tshwj xeeb thiab siv cov txheej txheem tiv thaiv yog tias tsim nyog. Tom qab sib cuag nrog cov tshuaj uas muaj cov xeb, kom sai sai ntxuav cov chaw nyob hauv qab kom tiv thaiv ntev- lub corrosion.
4. Tsis tu ncua thiab txij nkawm
Thaum siv, hmoov av, oxides, lossis cov tshuaj tiv thaiv cov tshuaj tiv thaiv yuav tau tso rau saum npoo ntawm cov phaj graphite. Ntxuav huv tsis tu ncua nrog daim ntaub mos muag lossis txhuam, zam kev khawb nrog cov cuab yeej nyuaj. Yog tias cov nplaim hluav taws xob tsis zoo, kho nrog dilute acid lossis organic cov kuab tshuaj ntawm cov kub kub, tab sis kev tawm dag zog kom tiv thaiv corrosion. Cia nws qhuav thaum lub sijhawm cia kom tsis txhob muaj kev nqus dej noo thiab deformation.
5. Npaj qhov hloov cov hloov tsheb kauj vab
Graphite daim hlau yog colenables thiab yuav hnav los yog degrade hauv kev ua tau zoo tom qab ntev - siv. Nws raug nquahu kom tsis tu ncua xyuas lawv cov tuab, qhov chaw nyob, thiab conductivity. Hloov cov hnav uas pom tau pom lossis cov kab nrib pleb kom ntseeg tau tias muaj kev nyab xeeb ntawm cov cuab yeej.
Ua raws li cov lus qhia saum toj no yuav tsis tsuas yog lub neej ntawm koj daim ntawv graphite, tab sis kuj txhim kho nws cov nqi kho mob thiab txo cov nqi kho. Kev siv thiab kev saib xyuas zoo yog tus yuam sij rau kev ua tiav qhov kev ua tau zoo tshaj plaws ntawm koj daim ntawv graphite.
