Universal Surface Material Hardness Tester / Hlau Siv Lub Tshuab Kuaj Hlau
Kev piav qhia:
1. Lub zog tawv yog ib qho tseem ceeb ntawm cov khoom siv hlau thaum cov khoom siv kuaj xyuas yog qhov nrawm tshaj plaws thiab kev sim kev lag luam, nrog rau txoj kev tseem ceeb los txiav txim siab qhov zoo ntawm cov khoom siv hlau lossis nws cov khoom sib xyaw. Cov kws kho tsheb cov yam ntxwv ntawm cov khoom siv hlau ntau tshaj plaws xws li lub zog, nkees, wriggling thiab hnav tawm tuaj yeem kuaj xyuas kwv yees los ntawm nws qhov kev xeem hardness.
2. Lub cev muaj zog Brinell Rockwell & Vickers Hardness Tester, ntau qhov kev sim kuaj cov khoom siv nrog Brinell, Rockwell & Vickers 3 yam ntawm cov qauv kuaj thiab 7 kauj ruam kuaj quab yuam yuav ua tau raws li cov kev xav tau ntawm ntau yam kev ntsuas qhov ntsuas. Qhov ntsuas yog saws cov tsis siv neeg hloov mus thauj khoom, chaw nyob thiab tsis siv zog kuaj, yog li kev ua haujlwm rau qhov ntsuas no yog qhov yooj yim, yooj yim thiab nrawm.
