Ireyithi yokusikaibhekisa kwisiqingatha seglasi yobungakanani obufanelekileyo obufunekayo emva kweglasi esikiweyo phambi kokupolisha.
Ifomula ifanelekile iglasi kunye nobukhulu obufunekayo qty x ubude beglasi obufunekayo x ububanzi obufunekayo beglasi / ubude bephepha leglasi ekrwada ububanzi = ireyithi yokusika
Ke ekuqaleni, kufuneka sifumane ukuqonda okucacileyo kubungakanani bephepha leglasi ekrwada kwaye zingaphi iimilimitha (mm.) ekufuneka ziyishiye kubude beglasi kunye nobubanzi xa usikwa:
| Ukutyeba kweglasi (mm) | Ubungakanani bephepha leglasi ekrwada esemgangathweni (mm) | Imilimitha kufuneka ishiye iglasi L. & W. (mm) |
| 0.25 | 1000×1200 | 0.1-0.3 |
| 0.4 | 1000×1500 | 0.1-0.3 |
| 0.55/0.7/1.1 | 1244.6×1092.2 | 0.1-0.3 |
| 1.0/1.1 | 1500×1900 | 0.1-0.5 |
| ngaphezulu kwe-2.0 | 1830×2440 | 0.5-1.0 |
| 3.0 & ngaphezulu kwe-3.0 | 1830×2400;2440×3660 | 0.5-1.0 |
Umzekelo:
| Ubungakanani beglasi obufunekayo | 454x131x4mm |
| Ubungakanani bePhepha leGlasi eliMgangatho | 1836x2440mm;2440x3660mm |
| Imilimitha kufuneka ishiye iglasi L. & W. (mm) | 0.5mm kwicala ngalinye |
| Ubungakanani bephepha leGlasi ekrwada | 1830 | 2440 | 1830 | 2440 |
| Ubungakanani beglasi obufunekayo kunye nokongeza mm xa usika | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| I-Qty emva kweshiti ekrwada yahlulwe ngobungakanani beglasi efunekayo | 4.02 | 18.48 | 13.86 | 5.36 |
| Iyonke iglasi ephumeleleyo qty | 4×18=72pcs | 13×5=65pcs | ||
| Ireyithi yokusika | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||
| Ubungakanani bephepha leGlasi ekrwada | 2240 | 3360 | 2240 | 3360 |
| Ubungakanani beglasi obufunekayo kunye nokongeza mm xa usika | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| I-Qty emva kweshiti ekrwada yahlulwe ngobungakanani beglasi efunekayo | 4.92 | 25.45 | 16.97 | 7.38 |
| Iyonke iglasi ephumeleleyo qty | 4×25=100pcs | 16×7=112pcs | ||
| Ireyithi yokusika | 100x454x131/2440/3660=66% | 112x454x131/2440/3660=75% | ||
Ke ngokucacileyo siye sazi, i-1830x2440mm ishidi eluhlaza lukhetho lokuqala xa usikwa.
Ngaba unayo ingcamango yokubala izinga lokusika?
