Izinga lokuSikaibhekisa kwinani leglasi elifunekayo emva kokuba iglasi isikiwe ngaphambi kokuba ipholishwe.
Ifomula yiglasi efanelekileyo enobungakanani obufunekayo ubungakanani x ubude beglasi obufunekayo x ububanzi beglasi obufunekayo / ubude bephepha leglasi eluhlaza / ububanzi bephepha leglasi eluhlaza = izinga lokusika
Ngoko ke, ekuqaleni, sifanele siqonde kakuhle ubungakanani bephepha leglasi eluhlaza eliqhelekileyo kunye nokuba zingaphi iimilimitha (mm.) ekufuneka zishiywe kubude nobubanzi beglasi xa zisikwa:
| Ubukhulu beglasi (mm) | Ubungakanani beGlasi eGlasi eGlasi eQhelekileyo (mm) | I-millimeter mayishiyeke kwiglasi ye-L. kunye ne-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 nangaphezulu 3.0 | 1830×2400;2440×3660 | 0.5-1.0 |
Umzekelo:
| Ubungakanani Beglasi Obufunekayo | 454x131x4mm |
| Ubungakanani bePhepha leGlasi eLuhlaza eliqhelekileyo | 1836x2440mm; 2440x3660mm |
| I-millimeter mayishiyeke kwiglasi ye-L. kunye ne-W. (mm) | 0.5mm kwicala ngalinye |
| Ubungakanani bePhepha leGlasi eluhlaza | 1830 | 2440 | 1830 | 2440 |
| Ubungakanani beglasi obufunekayo kunye nokongeza i-mm xa usika | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Ubungakanani emva kwephepha elingavulwanga lahlulwe ngobukhulu beglasi obufunekayo | 4.02 | 18.48 | 13.86 | 5.36 |
| Ubungakanani beglasi obufanelekileyo | 4×18=72pcs | 13×5=65pcs | ||
| Izinga lokuSika | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||
| Ubungakanani bePhepha leGlasi eluhlaza | 2240 | 3360 | 2240 | 3360 |
| Ubungakanani beglasi obufunekayo kunye nokongeza i-mm xa usika | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Ubungakanani emva kwephepha elingavulwanga lahlulwe ngobukhulu beglasi obufunekayo | 4.92 | 25.45 | 16.97 | 7.38 |
| Ubungakanani beglasi obufanelekileyo | 4×25=100pcs | 16×7=112pcs | ||
| Izinga lokuSika | 100x454x131/2440/3660=66% | 112x454x131/2440/3660=75% | ||
Ngoko ke ngokucacileyo sazi ukuba, iphepha eliluhlaza elingu-1830x2440mm lolona khetho luphambili xa usika.
Ngaba unayo ingcamango yokubala izinga lokunciphisa?
