420 SS (chitsulo chosapanga dzimbiri) waya wopopera ndi zinthu zapamwamba zomwe zimapangidwa kuti zizipopera mapulogalamu. Wodziwika chifukwa cha kukana kwake kwabwino kwambiri, kuuma kwambiri, komanso kuvala bwino kukana, kukana kwa 420 ss ndi chitsulo chosapanga dzimbiri chomwe chimapereka chipululu chokhazikika. Wayayu amagwiritsidwa ntchito monga mafakitale monga Petrokemical, m'badwo wamphamvu, magetsi, ndi ma rine kuti apititse patsogolo kukhazikika kwazinthu zotsutsa. Makina opopera 420 ssaral opindika ndi abwino pakugwiritsa ntchito zokutira zolimba, zosemphana ndi vuto lolimbana ndi kukana modabwitsa.
Kukonzekera koyenera ndikofunikira kuti mukwaniritse zotsatira zabwino ndi 420 ss ma utoto opopera. Pamwamba kukhala zokutira kuyenera kutsukidwa mosamala kuti muchotse zodetsa monga mafuta, mafuta, uve, ndi ma olima. Grit kuphulika ndi aluminium oxide kapena silican carbide tikulimbikitsidwa kuti akwaniritse mawonekedwe a 50-75 Microns. Nthaka yoyera komanso youluka imapangitsa kuti cholumikizira cha utsi wamafuta, zomwe zimapangitsa kuti zikhale ndi nthawi yotalikirana.

420 ss matenthedwe opopera ndi njira yabwino kwambiri yolimbikitsira malo opangira zinthu zomwe zimadziwika bwino. Kulimba kwake kwakukulu komanso kuvala bwino kuvalidwe kumapangitsa kuti zikhale zoyenera zogwirizira zolimba komanso zokhazikika. Pogwiritsa ntchito ma 420 ss ma utoto opopera, mafakitale amatha kusintha kwambiri za zida zautumiki ndi kudalirika kwa zida ndi zigawo zikuluzikulu.
