Kuchuluka kwa Ntchito
Fluorescent brightener PF-3 imagwiritsidwa ntchito makamaka pakuyera ndi kuwunikira PVC, polystyrene, polyacrylate, filimu ya poliyesitala, polyethylene yapamwamba komanso yotsika, ABS, plexiglass, makhadi abizinesi, mapepala apamwamba, ndi zina zambiri.
Mlingo
Njira yogwiritsira ntchito: Sakanizani kuwala kwa kuwala kwa PF-3 mu plasticizer yosankhidwa pa 0.03-0.1% ya kulemera kwa pulasitiki, ndiyeno pitirizani ndi teknoloji yopangira pulasitiki yomwe imagwiritsidwa ntchito.Onani apa kuti iyenera kusakanizidwa bwino.
Fluorescent lightener PF-3 imatha kusungunuka ndi plasticizer kenako ndikuyimitsidwa ndi mipukutu itatu kupanga chakumwa cha mayi.Kenako yang'anani mu PF-3 pulasitiki fulorosenti whitening wothandizira kuyimitsidwa uniformly pa processing, ndi kuupanga pa kutentha kwina (nthawi zimadalira kutentha), nthawi zambiri pa 120.～150 ℃ kwa mphindi 30, ndi 180～190 ℃ kwa mphindi imodzi.Ndiko kutulutsa zabwino zoyera komanso zowunikira.Kapena sakanizani mitundu yonse ya zopangira kaye, kenako onjezerani chowunikira cha PF, sakanizani molingana pa 160 ℃ kwa mphindi pafupifupi 5, kenako pindani mu mawonekedwe.
