Kugwiritsa ntchito

Photoinitiator 819, yomwe imadziwikanso kuti PI 819, itha kugwiritsidwa ntchito mu zokutira zapulasitiki zochiritsika za UV.Zovala za UV zakhala zikugwiritsidwa ntchito kwambiri m'nyumba zapulasitiki zazinthu zosiyanasiyana zamagetsi ndi zapanyumba chifukwa chakuchita bwino komanso kupanga bwino, koma zokutira za UV zimawonjezeredwa pambuyo kupaka utoto.Kuchiza kosakwanira, zomwe zimapangitsa kuti filimuyo isamamatire bwino, komanso kusabalalika bwino kwa pigment ndi utomoni wa UV, zomwe zimakhudza kwambiri mawonekedwe a filimu yokutira, motero njira yomanga yachikhalidwe imayamba kupakidwa utoto ndi utoto wosungunulira wopangira utoto. pambuyo kuphika Ikani UV varnish kusintha thupi katundu wa utoto filimu pamwamba.
