Nyob rau hauv xyoo tas los no, graphite pwm nyob rau hauv niaj hnub kev lag luam daim ntawv thov kev lag luam txuas ntxiv nthuav nws txoj hauj lwm, lub sij hawm no txawv ntawm yav dhau los, tam sim no graphite pwm twb ib tug qauv nyob rau hauv lub neej yav tom ntej.
Ua ntej, hnav tsis kam
Yog vim li cas vim li cas graphite pwm feem ntau ua tsis tiav vim hnav yog tias thaum lub pob zeb yog yas denaturated nyob rau hauv cov pwm kab noj hniav, nws ntws thiab swb raws li qhov chaw ntawm cov kab noj hniav, ua rau muaj kev sib txhuam ntawm qhov chaw ntawm cov kab noj hniav thiab cov hniav nyiaj hniav kub.
1, hnav tsis kam yog cuam tshuam nrog tus lej, qhov loj me, cov duab, hom thiab kev faib tawm ntawm carbides hauv cov khoom
2, ib qho ntawm cov khoom tseem ceeb ntawm graphite pwm yog qhov hnav tsis kam ntawm cov khoom;
3, lub ntsiab tseem ceeb cuam tshuam rau hnav tsis kam yog hardness. Qhov siab dua qhov hardness ntawm graphite qhov chaw, qhov tsawg dua qhov hnav, qhov zoo dua hnav tsis kam;
Thib ob, lub zog thiab toughness
Graphite pwm feem ntau yog siv rau hauv ib puag ncig hnyav, thiab qee qhov yuav tsum tau tiv taus qhov cuam tshuam loj heev, ua rau tawg tawg. Nws yog cov khoom lag luam siab purity graphite nrog cov toughness siab thiab lub zog, uas yog qhov tsim nyog los tiv thaiv qhov tawg sai sai ntawm pwm qhov chaw thaum ua haujlwm. Lub toughness yog feem ntau cuam tshuam nrog microstructure, grain loj thiab cov ntsiab lus carbon ntawm cov khoom.
