1. Ubukhulu
Izitishi ezi-7: Izitishi ezi-7 nge-intshi ngayinye.
Izitishi eziyi-12: Izitishi eziyi-12 nge-intshi ngayinye.
Uma inani lincipha, nezingubo zincipha.Inaliti enezinti ezintathu ijiyile futhi ivame ukugqokwa ebusika, kanti enezinti ezingu-12 incane futhi ingagqokwa ekwindla.
2. Ukukhetha izinaliti zokuthunga
12 Kukhona futhi ububanzi obuthile bokubalwa kwentambo yoboya, okungukuthi, ubukhulu boboya. Uma inani lezinaliti likhulu, uboya buyancipha.
Amakhono okukhetha uboya:
1.uboya obuthambile
Inombolo yokuqala yenombolo yesihloko ingu-"1" noma "2". Inombolo yokuqala "1" ikhombisa ukuthi intambo iphothwe ngoboya obuhlukahlukene. Izinto ezingu-168 no-170 ziphothwe ngoboya basekhaya bebanga lesi-3 nelesi-4, kanti intambo engu-180 no-116 ziphothwe ngoboya basekhaya bebanga loku-1 nelesi-2.
Uboya obunenombolo yokuqala ethi "2" enombolweni yesihloko buphothwe ngoboya obufanayo. Uboya obufanayo bunendinganiso ethile yobukhulu nobude boboya, kanti izinombolo zomkhiqizo ziyi-268, 272, 275, 219, njll.
2.Uboya obuhlanganisiwe: uboya obuhlanganiswe ne-acrylic kanye noboya obungafani, ingxenye yokuqala yenombolo yomkhiqizo ingu-"7". Ngoboya obuhlanganiswe noboya obufanayo kanye noboya obungafani, inombolo yokuqala yento ingu-"4". Ngoboya obuhlanganiswe noboya obufanayo kanye ne-acrylic fiber, inombolo yokuqala yenombolo yomkhiqizo ingu-"6".
3.Intambo yefayibha yamakhemikhali: inombolo yokuqala yenombolo yesihloko ingu-"8".
