Ibyiza
Optical brightener OB ni ubwoko bwa benzoxazole, ntabwo ari impumuro nziza, bigoye gushonga mumazi, gushonga muri paraffine, ibinure, amavuta yubutare, ibishashara hamwe nibisanzwe bisanzwe.Irashobora gukoreshwa mu kwera plastiki ya termoplastique, PVC, PS, PE, PP, ABS, Acetate fibre, irangi, gutwikira, wino yo gucapa, nibindi. ohereza ibara ryera ryera.
Gusaba
Optical brightener OB nimwe murumuri mwiza ukoreshwa cyane muri plastiki na fibre kandi ufite ingaruka zera nka Tinopal OB.Irashobora gukoreshwa muri thermoplastique, polyvinyl chloride, polystirene, polyethylene, polypropilene, ABS, acetate, kandi irashobora no gukoreshwa muri langi, amarangi, amabuye yera yera, impuzu, hamwe na wino. Ifite kandi ingaruka nziza yo kwera kuri fibre synthique. .Bifite ibyiza byo kurwanya ubushyuhe, guhangana nikirere, kutagira umuhondo, hamwe nijwi ryiza ryamabara. Irashobora kongerwaho kubintu bya monomer cyangwa prepolymerized mbere cyangwa mugihe cya polymerizasiyo, kondegene, kongera polymerisation, cyangwa byongewe muburyo bwa poro cyangwa pellet (ni ukuvuga masterbatch) mbere cyangwa mugihe cyo gukora plastike na fibre synthique.
Imikoreshereze:
1 PVC:
Kuri PVC yoroshye cyangwa ikomeye:
Kwera: 0.01－0.05% (10－50g / 100KG ibikoresho)
Mucyo: 0.0001－0.001% （0.1g － 1g / 100kg ibikoresho）
2 PS:
Kwera: 0.001% (1g / 100kg ibikoresho)
Mucyo: 0.0001－0.001 (0.1－1g / 100kg ibikoresho)
3 ABS:
Ongeraho 0.01-0.05% muri ABS birashobora gukuraho neza ibara ryumuhondo ryumwimerere kandi bigera ku ngaruka nziza yo kwera.
4 Polyolefin:
Ingaruka nziza yo kwera muri polyethylene na polypropilene:
Mucyo: 0.0005－0.001% (0.5－1g / 100kg ibikoresho)
Kwera: 0.005－0.05% (ibikoresho 5－50g / 100kg)
Amapaki
25kg fibre ingoma ， hamwe na PE umufuka imbere cyangwa nkuko umukiriya abisaba.
