koj yuav txiav txim siab qhov zoo ntawm daim kab xev li cas?
Nyob rau hauv qhov tseeb, muaj ob txoj kev cai nyob rau hauv kev siv ntawm kua nplaum nyob rau hauv nplaum tapes. Ib qho yog thawj zaug adhesion thiab ib qho yog qhov retention. Qhov ob yog inversely proportional. Raws li ib txwm muaj, lub zog ntawm nplaum yog qis dua 10 tus kab xev tsawg tshaj li cov yas txheej, feem ntau tsuas yog kwv yees li 20 microns, xws li ntawv xov xwm, daim kab xev rau cov khoom lag luam qis tshaj plaws. Thawj lub zog ntawm daim ntaub nplaum nruab nrab yog nruab nrab ntawm 15-20. Lub thickness ntawm daim kab xev kua nplaum yog feem ntau 22-28 microns. Nws yog ib qho thickness. Txawm li cas los xij, feem ntau ntawm cov nplaum nplaum rau lub lag luam yog impregnated nrog impurities, yog li ntawd lub thickness yog nce mus rau daim npog lub impurities. Lub kua nplaum tseem doped nrog toner, yog li cov kab xev nplaum tshwm li qe-dawb thiab daj ntseg ntsuab. Xws li cov tapes feem ntau tsis zoo.
