Katundu

Optical brightener OB Fine ndi mtundu wa benzoxazole pawiri, alibe fungo, zovuta kusungunuka m'madzi, sungunuka mu parafini, mafuta, mchere mafuta, sera ndi wamba organic solvents.Iwo angagwiritsidwe ntchito whitening mapulasitiki thermoplastic, PVC, PS, Pe, PP, ABS, Acetate CHIKWANGWANI, utoto, ❖ kuyanika, inki yosindikiza, etc. Iwo akhoza kuwonjezeredwa pa siteji iliyonse m'kati whitening ma polima ndi kupanga zomalizidwa mankhwala. zimatulutsa kuwala kowala koyera koyera.

Kugwiritsa ntchito

Optical brightener OB Fine ndi imodzi mwazowunikira bwino kwambiri zomwe zimagwiritsidwa ntchito kwambiri mu mapulasitiki ndi ulusi ndipo zimakhala ndi zoyera ngati Tinopal OB.Itha kugwiritsidwa ntchito mu thermoplastics, polyvinyl chloride, polystyrene, polyethylene, polypropylene, ABS, acetate, ndipo itha kugwiritsidwanso ntchito mu ma varnish, utoto, ma enamel oyera, zokutira, ndi inki. .Ili ndi ubwino wa kukana kutentha, kukana kwa nyengo, kusakhala kwachikasu, ndi tone yabwino yamtundu. Ikhoza kuwonjezeredwa ku monomer kapena zinthu zowonongeka kale kapena panthawi ya polymerization, condensation, kuwonjezera polymerization, kapena kuwonjezeredwa mu mawonekedwe a ufa kapena pellets. (ie masterbatch) isanapangidwe kapena pakupangidwa kwa mapulasitiki ndi ulusi wopangira.

Kagwiritsidwe:

1 PVC:

Kwa PVC yofewa kapena yolimba:

Kuyera: 0.01-0.05% (10-50g/100KG zakuthupi)

Zowonekera: 0.0001-0.001% (0.1g-1g/100kg zakuthupi)

2 PS:

Kuyera: 0.001% (1g/100kg zakuthupi)

Zowonekera: 0.0001-0.001 (0.1-1g/100kg zakuthupi)

3 ABS:

Kuwonjezera 0.01-0.05% ku ABS kumatha kuthetsa bwino mtundu wachikasu woyambirira ndikukwaniritsa bwino kuyera.

4 Polyolefin:

Zabwino zoyera mu polyethylene ndi polypropylene:

Zowonekera: 0.0005-0.001% (0.5-1g/100kg zakuthupi)

Kuyera: 0.005-0.05% (5-50g/100kg zakuthupi)
