I-UV-123 inamandla okuzinzisa ukukhanya kwe-amine, kunye ne-alkaline ephantsi, inokunciphisa ukusabela kunye namacandelo e-asidi kwinkqubo yokugquma, efanelekileyo kakhulu kwinkqubo equlethe izinto ezikhethekileyo ezifana ne-acid substance kunye ne-catalyst residue; inokuthintela ngokufanelekileyo ukulahleka kokukhanya, ukuqhekeka, ukuphosa amagwebu, ukuwa kunye nokuguqulwa kombala, ngaloo ndlela iphucula ubomi benkonzo yokugquma; sebenzisa nge-absorbent ye-ultraviolet ukuphumeza usetyenziso olungcono lokumelana nemozulu.
Ifanelekile: iinqwelo zeemoto, iingubo zamashishini, iingubo zokuhombisa kunye neengubo zokhuni.
Yongeza inani: ngokubanzi 0.5-2.0%. Iimvavanyo ezifanelekileyo ziya kusetyenziswa ukumisela isixa esifanelekileyo esongezwa kusetyenziso oluthile.
Ipakishwe kwi-25 Kg / idrum yeplastiki okanye i-200 Kg / igubu.
Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya.
