Katundu
Optical brightener OB-1 ndi chinthu chonyezimira, chili ndi fluorescence yamphamvu.Ndiwopanda fungo, ndi ovuta kusungunuka m'madzi.
Itha kugwiritsidwa ntchito poyeretsa ma polyesters, ulusi wa nayiloni ndi mapulasitiki osiyanasiyana monga PET, PP, PC, PS, PE, PVC, etc.
Kugwiritsa ntchito
1.Zoyenera kuyera za ulusi monga poliyesitala, nayiloni ndi polypropylene.
2.Zoyenera kuyera ndi kuwala kwa pulasitiki ya Polypropylene, ABS, EVA, polystyrene ndi polycarbonate etc.
3.Zoyenera kuwonjezera pa polymerization wamba wa polyester ndi nayiloni.
