Nyob rau hauv xyoo tas los no, graphite pwm nyob rau hauv kev lag luam niaj hnub no daim ntawv thov kev lag luam txuas ntxiv nthuav nws txoj haujlwm, lub sijhawm no yog txawv ntawm yav dhau los, tam sim no graphite pwm twb yog ib qho kev sib txawv yav tom ntej.
Ua ntej, hnav tsis kam
Qhov laj thawj uas ua rau cov pwm graphite feem ntau tsis ua haujlwm vim yog hnav yog tias thaum lub billet yog yas denaturated hauv lub pwm qhov, nws ntws thiab swb raws qhov chaw ntawm lub qhov, ua rau muaj kev sib txhuam hnyav ntawm qhov chaw ntawm lub qhov thiab lub billet.
1, kev hnav tsis kam yog cuam tshuam nrog tus lej, qhov loj me, cov duab, hom thiab kev faib tawm ntawm cov carbides hauv cov khoom siv
2, ib qho ntawm cov khoom tseem ceeb ntawm graphite pwm yog qhov hnav tsis kam ntawm cov khoom siv;
3, qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev hnav tsis kam yog qhov nyuaj. Qhov nyuaj ntawm cov khoom graphite siab dua, qhov hnav me dua, qhov hnav tsis kam zoo dua;
Qhov thib ob, lub zog thiab kev ua tau zoo
Feem ntau cov pwm graphite siv rau hauv qhov chaw nyuaj, thiab qee qhov yuav tsum tau tiv taus qhov hnyav loj, ua rau tawg yooj yim. Nws yog cov khoom graphite purity siab nrog lub zog thiab lub zog siab, uas yog qhov zoo rau kev tiv thaiv kev tawg yooj yim ntawm cov pwm thaum ua haujlwm. Lub zog yog feem ntau cuam tshuam nrog cov qauv me me, qhov loj me ntawm cov noob thiab cov ntsiab lus carbon ntawm cov khoom.
