Ubumsulwa bamaphrofayili e-aluminium ezimbonini buzonquma ikhwalithi iyonke, enomthelela omkhulu ebulukhunini bomkhiqizo kanye nokuphila kwesevisi. Embonini, ubumsulwa bamaphrofayili e-aluminium ezimbonini buhlukaniswe ngamagremu amathathu, futhi njengomkhiqizi omuhle kakhulu iminyaka engama-20, okulandelayo ukuhlukaniswa okuqondile kwala magremu amathathu yimboni ekhethekile ye-aluminium kubasebenzisi abaningi!
I-Purity standard 1 yephrofayili ye-aluminium yezimboni: ingafinyelela cishe ku-90% ubumsulwa. Le nto ithandwa kakhulu emakethe, inoketshezi olukhulu kanye nentengo ephansi, okukhanga kakhulu abasebenzisi abanezidingo ezincane zekhwalithi.
Izinga lokuhlanzeka 2 lamaphrofayili e-aluminium yezimboni: ubumsulwa bungaba ngu-95%, okungaphezu kwezinga elijwayelekile lekhwalithi, ngakho intengo iphakeme kuneyemikhiqizo evamile yokuhlanzeka, futhi abasebenzisi ikakhulukazi bangabakhiqizi bekhwalithi ephezulu.
Izinga elijwayelekile lesi-3 lokuhlanzeka kwamaphrofayili e-aluminium ezimbonini: ubumsulwa buphakeme kunobamaphesenti angamashumi ayisishiyagalolunye nesikhombisa, okuyikhwalithi ethuthukisiwe embonini, futhi intengo ayifuni ukuthwalwa amabhizinisi amancane. Abasebenzisi abayinhloko ngokuvamile amabhizinisi kahulumeni noma amabhizinisi amakhulu azimele.
