Qhov saum npoo yog ua cov roj-resistant (xws li roj thiab txheej), yog li cov ntiv tes thiab cov roj tsis yooj yim rau saum npoo thiab yooj yim los ntxuav.
Ua tiav kev sib txuas, tsis siv neeg adsorption tuaj yeem rov ua qhov tseem ceeb ua ke
Surface hardness: Lub hardness nto yog 8-9h, uas yog 9 npaug zog dua li cov tsom iav zoo tib yam.Cov cuab yeej thiab cov yuam sij tsis raug txiav
Exquisite kov: Sab nraub qaum ntawm cov nplaum uas yooj yim rau nruab yog nyob ze rau ntawm lub vijtsam, yog li nws yuav tsis cuam tshuam rau qhov kov rhiab heev ntawm lub vijtsam kov.
Nws yog ib puag ncig, tsis muaj kua nplaum
High-txhais, 9H hardness, khawb tsis kam, tawg pov thawj, tiv thaiv ntiv tes
