Fluorescent Brightener 28 CAS 4193-55-9 ni iki?

Fluorescent Brightener 28 ni igikoresho cyo guhanagura urumuri gishingiye kuri bis-triazinylaminostilbene (OBA) gifite ubushobozi bwo hejuru. Optical brightener 28 ifata urumuri rwa ultraviolet (300-400 nm) ikongera kuyishyira mu mwanya wayo nk'urumuri rw'ubururu-violet (400-500 nm), igapfuka neza umuhondo w'ibice by'inyuma kandi igatanga isura nziza kandi y'umweru. Optical Brightener 28 ihabwa agaciro cyane mu gukoresha polymer no gusiga irangi kubera ubushyuhe bwayo bwiza kandi ihura neza.

Porogaramu

(1) Inganda zikora pulasitiki:
Imashini ikoresha urumuri rw'umutuku 28 ikoreshwa cyane mu gutunganya imiterere y'izuba nka PVC, PP, PE, ABS, PS, na plastiki z'ubuhanga kugira ngo yongere urumuri n'ubuziranenge.
(2) Irangi n'amabara:
Irangi ry’inyubako, irangi ry’inganda, irangi ry’imodoka, n’uburyo bwo gupima imirasire y’izuba.
(3) Fibres zikoze mu buryo bwa sintetike:
Imashini ikoresha urumuri 28 ikoreshwa mu kurangiza cyangwa gushyira ibara ryinshi rya polyester, nylon, na acetate kugira ngo igire umweru mwiza cyane.
(4) Inki na Masterbatches:
Inyongeramusaruro z'ingenzi mu irangi ryihariye ryo gucapa n'amabara meza y'umweru kugira ngo umweru urusheho gukora neza.
(5) Impapuro n'amasabune:
Ikoreshwa mu mpapuro nziza kandi nk'umurimbo w'urumuri mu buryo bumwe na bumwe bw'isabune yo mu nganda.

Ibiranga

(1) Ikora neza cyane mu kwera: Itanga urumuri rwinshi rw'ubururu n'umweru hamwe n'urugero rwo kongeramo (ubusanzwe 0.01%-0.1%).
(2) Gukomera cyane mu bushyuhe: Ihangana n'ubushyuhe busanzwe bwo gutunganya polymer kugeza kuri 250-300°C nta kwangirika gukomeye.
(3) Kwihuta mu rumuri: Bitanga ubudahangarwa buhagije bwo gucika intege mu gihe cy'igihe kirekire cy'imirasire ya UV.
(4) Guhuza neza na polymere yagutse: Bijyanye n'ubwoko bwinshi bwa polymer matrices na resin systems.
(5) Byoroshye gukwirakwizwa: Bishobora gushyirwa mu buryo bworoshye muri polymer binyuze mu gushonga cyangwa mu buryo bw'amazi binyuze mu gukwirakwizwa kw'umuvuduko mwinshi.
