Kusiyana pakugwiritsa ntchito mawilo a bulauni ndi oyera a corundum

Vuto lakugaya mbali ndi mawilo opukutira a brown corundum ndikuti malinga ndi malamulo, kugwiritsa ntchito malo ozungulira ngati malo ogwirira ntchito a gudumu lopukutira sikoyenera kugaya mbali. Mtundu uwu wa gudumu lopera uli ndi mphamvu zambiri za radial ndi mphamvu yochepa ya axial. Wogwiritsa ntchito akagwiritsa ntchito mphamvu zambiri, zimatha kupangitsa kuti gudumu lopera lisyoke komanso kuvulaza anthu. Khalidweli liyenera kuletsedwa pakugwiritsa ntchito kwenikweni.

Brown corundum akupera gudumu: Brown corundum ali ndi kuuma mkulu ndi kulimba, kuti akhale oyenera pogaya zitsulo ndi mkulu amakokedwa mphamvu, monga carbon chitsulo, aloyi chitsulo, malleable kuponyedwa chitsulo, mkuwa wolimba, etc. Mtundu uwu wa abrasive uli ndi ntchito yabwino yopera ndi kusinthasintha kwakukulu, ndipo amagwiritsidwa ntchito pogaya movutikira ndi malire akuluakulu. Ndizotsika mtengo ndipo zitha kugwiritsidwa ntchito kwambiri.

White corundum akupera Gudumu: Kulimba kwa corundum koyera ndikokwera pang'ono kuposa kofiira kofiira, pomwe kulimba kwake kumakhala kotsika kuposa kofiira kofiira. Pa akupera, ndi abrasive particles sachedwa kugawanika. Choncho, kutentha kopera kumakhala kochepa, zomwe zimapangitsa kuti zikhale zoyenera kupanga mawilo opera kuti azipera bwino zitsulo zozimitsidwa, zitsulo za carbon, zitsulo zothamanga kwambiri, ndi ziwalo zoonda kwambiri. Mtengo wake ndi wapamwamba kuposa wa brown corundum.
