Qhov cuam tshuam ntawm qhov kub siab ntawm cov roj carbon txhuam ntawm lub cev muaj zog ua rau qhov kub thiab txias ntawm cov pa roj carbon txhuam ntawm lub cev muaj zog kom siab dhau los yog hnav tsis zoo.

Kev cuam tshuam ntawm qhov kub thiab txias ntawm cov roj carbon txhuam ntawm lub cev muaj zog ua rau qhov kub thiab txias ntawm cov pa roj carbon txhuam ntawm lub cev muaj zog los yog hnav tsis zoo, yog li koj yuav tsum xyuam xim rau nws thaum siv nws. Piv nrog cov hlau sau cov nplhaib, cov nplhaib tooj liab xws li tooj liab castings muaj cov yam ntxwv zoo zawv zawg, yog li lawv tau siv dav, tab sis thaum lawv muaj cov hmoov txhuas loj uas tsis tshua muaj melting point, lawv raug deleaded vim cua sov ntawm lub energizing point, uas yog ib qho yooj yim ua rau hnav ntawm lub nplhaib collector lossis txawv txav ntawm txhuam. Nyob rau hauv kev sib koom tes ntawm lub nplhaib collector thiab txhuam, thaum lub abrasiveness ntawm cov pa roj carbon txhuam yog muaj zog heev thiab cov khoom ntawm lub nplhaib collector yog mos heev, lub stepped hnav sib npaug rau qhov dav ntawm txhuam feem ntau tshwm sim ntawm lub nplhaib collector. Tshwj xeeb, tag nrho cov motors uas muaj qhov kub thiab txias thiab cov av noo tsis tshua muaj feem ntau yuav ua rau hnav cov txhuam hniav ntau dhau los yog cov nplhaib sib sau.
