1. Qhov zoo ntawm Chrome-Plated Rollers: Zoo Hardness. Piv nrog rau ib puag ncig ntuj ntawm kev siv ntau lawm, qhov hardness tom qab kev kho cua sov yog piv rau carbon steel thiab lwm yam hlau kav thiab sib npaug puag ncig steel. Lwm cov txheej txheem kho cua sov, xws li nitriding, siab - zaus quenching, thiab siab - zaus tempering, yog me ntsis qis dua. Hauv kev ntsuas qhov ua tau zoo, qhov nyuaj ntawm chrome-plated rollers yog feem ntau ntawm 55-65 Rockwell degrees.
2. Hnav-Resistant nrog kev sib txhuam qis. Raws li qhov hardness ntawm chrome-plated steel rollers nce, kev sib txhuam coefficient kuj txo qis nrog rau kev nce hauv smoothness, yog li txo cov kev pab cuam lub neej ntawm chrome-plated steel rollers.
3. Stable Chrome Plating: Vim hais tias chrome plating txheej ntawm chrome-plated rollers ruaj khov nyob rau hauv ib puag ncig sib txawv, nws tsis yooj yim rau kev hloov tshuaj lom neeg thiab tsis yooj yim corroded los ntawm qee cov kua qaub lossis alkaline kua lossis roj.
