Application
Optical brightener KCB ndechimwe chezvakanakisa zvigadzirwa pakati peakawanda fluorescent whitening agents.Yakasimba yekuchena mhedzisiro, yakajeka yebhuruu uye yakajeka ruvara, ine yakanaka kupisa kupisa, kuramba mamiriro ekunze uye kugadzikana kwemakemikari.Inonyanya kushandiswa kuchena kwepurasitiki uye yekugadzira fiber zvigadzirwa, uye zvakare ine yakajeka inopenya mhedzisiro pane zvisiri-ferrous mapurasitiki zvigadzirwa.Inoshandiswawo zvakanyanya mu ethylene/vinyl acetate (EVA) copolymers, inova yakanakisa siyana yekupenya inopenya mune shangu dzemitambo.Inoshandiswawo zvakanyanya muPE, PP, PVC, PS, ABS, PMMA nemamwe mafirimu epurasitiki, zvinhu zvekuumba, jekiseni rekugadzira zvinhu uye polyester fibers.Iyo inewo mhedzisiro yakakosha pakuchena kwependi uye pendi dzechisikigo.Iyi yakasiyana-siyana ndiyo yakaderera muchetura pakati pemhando dzakawanda dze whitening agents.United States inotaura kuti inogona kushandiswa kuchenesa chikafu chekurongedza zvinhu.
Reference Dosage
Kune mapurasitiki kana resin, iyo yakawanda dosage ndeye 0.01-0.03%, kureva kuti, anenge 10-30 magiramu eBC-111 fluorescent whitening agent inowedzerwa kune zana makirogiramu epurasitiki mbishi zvinhu.Mushandisi anogona kugadzirisa iyo chaiyo dosage yemuchena mumiriri zvinoenderana nezvinodiwa zvekuchena.Kana iyo ultraviolet inonyudza senge titanium dioxide yakawedzerwa kune epurasitiki mbishi zvinhu, iyo yakakwana huwandu hweiyo chena mumiriri inofanira kugadziridzwa zvakakodzera.
PE: 10-25g / 100kg epurasitiki mbishi zvinhu
PP: 10-25g / 100kg epurasitiki mbishi zvinhu
PS: 10-20g/100kg epurasitiki mbishi zvinhu
PVC: 10-30g/100kg epurasitiki mbishi zvinhu
ABS: 10-30g/100kg epurasitiki mbishi zvinhu
EVA: 10-30g / 100kg resin
Kana yakashandiswa mune yakajeka epurasitiki firimu, iyo referensi dosage yekupenya: 1-10g/100kg epurasitiki mbishi zvinhu.
Kurongedza: 25kg kadhibhodhi chigubhu chakamisikidzwa nebhegi repurasitiki kana kurongedzerwa zvinoenderana nezvinodiwa nevatengi
