Cov yam ntxwv ntawm cov txhuam hniav rau cov cuab yeej siv hluav taws xob feem ntau suav nrog ntau qhov ntom ntom, tiv taus, Rockwell hardness, thiab lwm yam.
Bulk density: Bulk density is a indicator of the composition of the brushes, thiab cov kev cai sib txawv ntawm cov txhuam hniav muaj cov kev xav tau sib txawv rau qhov ntsuas no, yog li ntawd, qhov kev thov rau txhuam hniav yuav tsum tau sim rau lub sij hawm ntev kom haum rau kev siv cov motors.
Resistivity: ncaj qha cuam tshuam cov conductivity ntawm txhuam, thiab feem ntau cov irritability ntawm 30% thiab 60%. Qib ntawm resistivity yog ncaj qha ntsig txog cov conductivity ntawm txhuam
Rockwell hardness: Rockwell hardness yog hais txog tus nqi uas tau nyeem los ntawm Rockwell hardness tester ntawm lub siab tshwj xeeb los qhia qhov hardness ntawm cov txhuam hniav Cov tawv tawv yog ncaj qha cuam tshuam rau kev hnav tsis kam ntawm txhuam, siab tawv heev tuaj yeem coj hnav rau lub cev muaj zog. , thiab thaum lub hardness tsawg, cov txhuam yog yooj yim rau kev puas tsuaj yog li ntawd, rau cov motors sib txawv, cov txhuam hniav sib txawv hardness yuav tsum tau hloov.
