Njengamanje, izigaba ezivamile zezindwangu ezingalukiwe emakethe zingahlukaniswa zibe izinhlobo ezimbili: izindwangu ezivamile ezingalukiwe kanye nezindwangu zezokwelapha ezingezona ezilukiwe. Ngenxa yokusebenzisa kwabo okuyinhloko emikhakheni yezokwelapha, banezidingo eziqinile zekhwalithi. Ngaphezu kwalokho, yimuphi umehluko phakathi kwalokhu okubili?

1. Ikhono lokulwa namagciwane

Njengoba kuyindwangu yezokwelapha engalukiwe, indinganiso eyinhloko ikhono lokulwa namagciwane. Ngokuvamile, kusetshenziswa ungqimba olunezingqimba ezintathu ze-SMmms ezincibilika, kuyilapho izindwangu ezijwayelekile zezokwelapha ezingalukiwe zisebenzisa ungqimba olulodwa oluncibilikayo oluphephethayo. Uma kuqhathaniswa nalokhu okubili, isakhiwo esinezingqimba ezintathu kufanele sibe nekhono elinamandla lokulwa namagciwane. Ngokuqondene nezindwangu ezingezona ezezokwelapha ezingezona ezilukiwe, azinazo izinto ezilwa namagciwane ngenxa yokuntuleka kongqimba oluncibilikayo oluqhunyiswayo.

2. Ifanele izindlela ezihlukahlukene zokuvala inzalo

Njengoba inekhono lokulwa namagciwane, idinga nekhono lokuvala inzalo elihambisanayo. Izindwangu ezingezona ezilukiwe ezisezingeni eliphezulu zingalungela izindlela zokuvala inzalo ezahlukahlukene, okuhlanganisa umusi wokucindezela, i-ethylene oxide, ne-hydrogen peroxide plasma. Izindwangu ezingezona ezokwelashwa ezingalukiwe azikwazi ukusetshenziselwa izindlela eziningi zokuvala inzalo.

3. Ukulawulwa kwekhwalithi

Izindwangu zezokwelapha ezingalukiwe zidinga isitifiketi ngezinhlelo ezifanele zokulawula ikhwalithi yomkhiqizo, futhi kunezindinganiso nezimfuneko eziqinile zesinyathelo ngasinye senqubo yokukhiqiza.

Umehluko omkhulu phakathi kwezindwangu ezingezona ezilukiwe zezokwelapha kanye nezindwangu ezingezona ezilukiwe zibonakala ikakhulukazi kulezi zici. Ngayinye inokusetshenziswa kwayo nezici zayo, futhi inqobo nje uma ikhethwe ngendlela efanele ngokwezidingo ngesikhathi sokusetshenziswa.
