The photostabilizer UV770 ndi otsika maselo kulemera ankalepheretsa amine photostabilizer, amene ali ndi makhalidwe a ngakhale wabwino, kusinthasintha otsika, kubalalitsidwa bwino, otsika kuyenda, wabwino matenthedwe bata ndi mkulu kuwala bata, ndipo si kuyamwa kuwala koonekera ndipo sizimakhudza mtundu. Pakuti pamwamba ndi wandiweyani gawo la yopapatiza gulu, akamaumba, pali photostability kwambiri. Ndi mawonekedwe apamwamba a ma cell light stabilizer ndi ultraviolet absorber, synergistic effect ndiyofunikira.
Makamaka ntchito: polyethylene, polypropylene, polystyrene, olefin copolymer, poliyesitala, zofewa polyvinyl kolorayidi, polyurethane, polyformaldehyde ndi polyamides, zomatira ndi zisindikizo ndi zina zotero.
Kuchulukitsa kolimbikitsidwa: nthawi zambiri 0.05-0.60%. Mayesero oyenerera adzagwiritsidwa ntchito kuti adziwe kuchuluka koyenera kuwonjezeredwa pakugwiritsa ntchito.
Odzaza mu 25 Kg / katoni. Kapena odzaza malinga ndi makasitomala amafuna.
Sungani pamalo ozizira, owuma ndi mpweya wabwino; pewani kuwala kwa dzuwa.
Chonde titumizireni zolemba zilizonse zokhudzana ndi izi.
New Venture Enterprise yadzipereka kuti ipereke HALS yapamwamba kwambiri kuti ikwaniritse zosowa zosiyanasiyana zamafakitalewa, kuyendetsa luso komanso kukhazikika pakupanga zinthu, chonde titumizireni:
