Izici eziyinhloko zamashubhu akhanyayo ngokunemba:
Ipayipi elinokunemba odongeni, ukuqedwa kwekhwalithi ephezulu, ungqimba lwe-oxide yensimbi engashisi, udonga lwangaphakathi lwensimbi ehlanzekile ukuze imelane nokucindezela okuphezulu, ukuwohloka okubandayo, ukuvutha, ukwenza isicaba akukho mifantu, kungenza ukuguga okuhlukahlukene okuyinkimbinkimbi nokucubungula imishini. . Umbala wepayipi: omhlophe ngokugqamile, nokucwebezela kwensimbi ephezulu.

Izinjongo eziyinhloko zokunemba kwamashubhu akhanyayo:
Imoto, imishini nezinye izesekeli ezisetshenziselwa ukunemba kwepayipi lensimbi, qeda izidingo eziphakeme zemishini. Futhi manje kubasebenzisi bokunemba kwensimbi enembayo, qedela abasebenzisi abafunwa kakhulu, futhi ngenxa yokunemba okuphezulu ukubekezelela ukunemba kwepayipi lokukhanya kungagcinwa ngocingo oluyi-2–8, abasebenzisi abaningi bemishini ukuze bonge abasebenzi, izinto zokwakha, ukulahlekelwa isikhathi, insimbi engenamthungo. ipayipi noma ibha iguqulwa kancane ibe ipayipi lokukhanya elinembayo.
