Properties
Optical brightener OB imhando ye benzoxazole musanganiswa, haina hwema, inonetsa kunyungudika mumvura, inonyungudika muparafini, mafuta, mineral oil, wax uye common organic solvents.Inogona kushandiswa kuchenesa thermoplastic mapurasitiki, PVC, PS, PE, PP, ABS, Acetate faibha, pendi, coating, kudhinda ingi, etc. Inogona kuwedzerwa chero nhanho mukuita chena mapolima uye kugadzira zvigadzirwa zvakapedzwa. inoburitsa ruvara rwebluish chena glaze.
Application
Optical brightener OB ndeimwe yeakanakisa kupenya anoshandiswa zvakanyanya mumapurasitiki nemafibhi uye ine chena yakafanana neTinopal OB.Inogona kushandiswa mu thermoplastics, polyvinyl chloride, polystyrene, polyethylene, polypropylene, ABS, acetate, uye inogonawo kushandiswa mumavarnish, pendi, machena enamel, machira, uye inks.Iyo zvakare ine yakanaka kwazvo yekuchena mhedzisiro pamafibhi ekugadzira. .Ine zvakanakira kupisa kupisa, kuramba kwemamiriro ekunze, kusaita yero, uye yakanaka mavara tone.Inogona kuwedzerwa kune monomer kana prepolymerized zvinhu zvisati zvaitika kana panguva yepolymerization, condensation, kuwedzera polymerization, kana kuwedzerwa muchimiro chehupfu kana mapellets. (kureva masterbatch) isati yasvika kana panguva yekuumbwa kwepurasitiki nemafuta ekugadzira.
