I-UV327 ingakwazi ukumunca kakhulu ukukhanya kwe-ultraviolet okungu-300-400nm, ukuzinza okuhle kwamakhemikhali, ukuguquguquka okuphansi, ukuhambisana kahle ne-polyolefin, okuguquguqukayo okuphansi, ubuthi obuphansi, obungashi, akukho ukugqwala, ukuzinza okuhle kwesitoreji, nokusebenzisana okubalulekile ne-DLTDP (PS800). Ifaneleka ngokukhethekile kuma-polymers azwela kakhulu emisebeni ye-wavelength ultraviolet (isb, i-polyimidites, i-polyphenyl sulfide) kanye nezinhlelo zokusebenza ezidinga ukudluliselwa okuphansi emisebeni ye-wavelength ultraviolet (isb, ilensi yokubona).
Isetshenziswa kakhulu ku-polyvinyl chloride, i-polystyrene, i-resin unsaturated, i-polyurethane, i-polymethyl methacrylate, i-polyethylene, i-ABS resin, i-polypropylene fiber, upende, i-ejenti yombala, izinto zokunamathisela nezinye izinsimbi nezinye izinkambu eziningi.
Ipakishwe ku-20 noma 25 Kg / ibhokisi. Noma kupakishwe ngokwezidingo zamakhasimende.
Gcina endaweni epholile, eyomile futhi engenawo umoya; gwema ukukhanya kwelanga okuqondile.
Sicela usithinte nganoma yimaphi amadokhumenti ahlobene.
I-New Venture Enterprise izinikele ekuhlinzekeni iziqinisi zokukhanya ezisezingeni eliphezulu ukuze kuhlangatshezwane nezidingo ezahlukahlukene zalezi zimboni, ukushayela ubuhlakani obusha nokuzinza ekuthuthukisweni komkhiqizo, sicela usithinte:
