Kev siv cov khoom siv raw khoom rov ua dua tshiab hauv kev tsim cov graphite electrode feem ntau pom tseeb hauv kev npaj cov electrodes rov ua dua tshiab. Cov electrodes rov ua dua tshiab yog ua los ntawm kev ua cov khoom seem txiav lossis cov khoom siv graphite pov tseg los ntawm cov txheej txheem yooj yim xws li kev tsoo, molding, thiab ci. Txawm hais tias cov electrodes rov ua dua tshiab muaj cov hluav taws xob conductivity qis dua me ntsis piv rau cov electrodes graphite dag, nrog rau qhov resistivity kwv yees li 1.5 npaug ntawm cov electrodes graphite, lawv muaj cov txiaj ntsig xws li tus nqi qis, yooj yim ntawm kev npaj, thiab rov siv dua. Txawm li cas los xij, cov electrodes rov ua dua tshiab raug kev txom nyem los ntawm qhov ceev qis, tsis muaj zog siab, thiab nyiam tawg thaum siv, ua rau lawv tsis haum rau cov chaw muaj zog thiab kev co siab. Yog li ntawd, kev siv cov khoom siv raw khoom rov ua dua tshiab hauv kev tsim cov graphite electrode tseem txwv.

Kev Tshawb Fawb Txog Qhov Nyuaj Hauv Kev Hloov Cov Roj Av Coke Ib Txwm Muaj
