UV-928 ndi benzotriazole UV absorber, wokhoza kuyamwa 270-380 nm ultraviolet kuwala, ndi mlingo wapamwamba mayamwidwe 303 nm ndi 345 nm. Lili ndi makhalidwe ogwirizana bwino, kusinthasintha kochepa, kubalalitsidwa kwabwino, kuyenda kochepa, kukhazikika kwabwino kwa kutentha komanso kuyamwa kwakukulu, ndipo ndi koyenera kuchiritsa kutentha kwakukulu, kupaka ufa ndi kupukuta zitsulo. Kuphatikizidwa ndi kuwala kokhazikika kwa UV292 ndi UV123, kumathandizira kwambiri kukhazikika kwa zokutira, ndikuletsa kutayika kwa kuwala, kusinthika, ming'alu, ndi delamination.
Amagwiritsidwa ntchito makamaka mu: zokutira zamagalimoto, zokutira koyilo, zokutira za ufa.
Kuchuluka kovomerezeka: 1.0-3.0%, kuchuluka kwake kumatsimikiziridwa malinga ndi kuyesa kwa kasitomala
Odzaza mu 20 kapena 25 Kg / katoni.
Sungani pamalo ozizira, owuma ndi mpweya wabwino; pewani kuwala kwa dzuwa.
Chonde titumizireni zolemba zilizonse zokhudzana ndi izi.
New Venture Enterprise idadzipereka kuti ipereke zowongolera zowunikira zapamwamba kwambiri kuti zikwaniritse zosowa zosiyanasiyana zamafakitalewa, kuyendetsa luso komanso kukhazikika pakukula kwazinthu, chonde titumizireni:
