Ifoto ya UV770 ni uburemere buke bwa molecular ibangamira amine ifoto ishimishije, bikagira ibiranga itandukaniro ryiza, ihindagurika rito, ntirukurura urumuri rugaragara kandi ntirugira ingaruka kumabara. Kubuso hejuru hamwe nigice kinini cyitsinda rigufi, kubumba, hari amato meza. Hamwe nuburemere bwimisozi miremire kandi ultraviolet absorber, ingaruka za synorgistic ni ngombwa.
Ahanini birakoreshwa kuri: polthylene, polypropylene, Polyfyrene, Polyfin Copolymer, Polyethane, Polyine, Polyviny, Polyviny, Polyviny, Polfornaldehyde na poltiamies nibindi.
Byasabwe kwiyongera kwinyongera: Mubisanzwe 0.05-0-00%. Ibizamini bikwiye bizakoreshwa mu kumenya amafaranga akwiye yongerewe gukoreshwa.
Yuzuye muri 25 kg / ikarito. Cyangwa yapakiwe nkuko abakiriya basabwa.
Kubika ahantu hakonje, byumye kandi bihumeka; Irinde izuba.
Nyamuneka twandikire kubintu byose bifitanye isano.
Uruganda rushya rwa Venture rwahariwe gutanga ibishya byujuje ubuziranenge bwo guhangana nizindi nganda zikenewe, guhanga udushya no kuramba mugutezimbere ibicuruzwa, nyamuneka twandikire:
