I-photostabilizer UV770 iyisisindo esiphansi samangqamuzana esivimbelwe i-amine photostabilizer, enezici zokuhambisana okuhle, ukuguquguquka okuphansi, ukuhlakazeka okuhle, ukuhamba okuphansi, ukuqina okuhle kokushisa kanye nokuzinza okuphezulu kwe-optical, futhi ayimumbi ukukhanya okubonakalayo futhi ayithinti umbala. Kundawo ephakeme nengxenye ewugqinsi yebhande elincane, ukubumba, kukhona ukuhleleka okuhle kwezithombe. Ngokuqina kokukhanya kwamangqamuzana aphezulu kanye ne-ultraviolet absorber, umphumela we-synergistic ubalulekile.
Ikakhulukazi kusebenza: i-polyethylene, i-polypropylene, i-polystyrene, i-olefin copolymer, i-polyester, i-polyvinyl chloride ethambile, i-polyurethane, i-polyformaldehyde ne-polyamides, izinamathiselo nezimpawu nokunye.
Inani elingeziwe elinconyiwe: ngokuvamile ngu-0.05-0.60%. Izivivinyo ezifanele zizosetshenziswa ukuze kutholwe inani elifanele elingezwe ekusetshenzisweni okuthile.
Ipakishwe ku-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 izinikezele ekuhlinzekeni i-HALS yekhwalithi ephezulu ukuze ihlangabezane nezidingo ezihlukahlukene zalezi zimboni, ukushayela emisha kanye nokusimama ekuthuthukisweni komkhiqizo, sicela usithinte:
