imikhiqizo

izici zamakhemikhali

Ngokwesakhiwo samakhemikhali azo, zingahlukaniswa ngezigaba ezinhlanu:
1, uhlobo lwe-stilbene: olusetshenziselwa i-fibre kakotini kanye neminye imicu yokwenziwa, ukwenza iphepha, insipho kanye neminye imboni, ene-fluorescence eluhlaza okwesibhakabhaka;
2, uhlobo lwe-coumarin: olunesakhiwo esiyisisekelo se-coumarin, olusetshenziselwa i-celluloid, ipulasitiki ye-PVC, olune-fluorescence eluhlaza okwesibhakabhaka eqinile;
3, uhlobo lwe-pyrazoline: olusetshenziselwa uboya, i-polyamide, i-acrylic fiber kanye neminye imicu, enombala oluhlaza okwesibhakabhaka;
4, uhlobo lwe-benzoxy nitrogen: olusetshenziselwa imicu ye-acrylic kanye ne-polyvinyl chloride, i-polystyrene kanye nezinye ipulasitiki, olune-fluorescence ebomvu;
5, uhlobo lwe-benzoimide lusetshenziselwa i-polyester, i-acrylic, i-nylon nezinye izintambo, ezine-fluorescence eluhlaza okwesibhakabhaka.

Isingeniso somkhiqizo kanye nezici

I-Fluorescent brightener (i-fluorescent brightener) iyidayi elikhanyayo, noma idayi elimhlophe, okuyigama elijwayelekile leqembu lama-compounds. Isici sayo ukuthi ingavusa ukukhanya kwe-incident ukuze kukhiqize i-fluorescence, ukuze izinto ezingcolisiwe zibe nomphumela ofanayo we-fluorite glitter, ukuze ngeso lenyama zibone ukuthi izinto zimhlophe kakhulu.

sebenzisa

Incazelo yokuqala yenkolelo-mbono ye-fluorescence yafika ngo-1852, lapho uStokes ephakamisa lokho okwaziwa ngokuthi uMthetho kaStokes. Ngo-1921 uLagorio waphawula ukuthi amandla e-fluorescence abonakalayo akhishwa amadayi e-fluorescent ayephansi kunamandla okukhanya abonakalayo amuncwa yiwo. Ngenxa yalesi sizathu, waphetha ngokuthi amadayi e-fluorescent ayenamandla okuguqula ukukhanya okungabonakali kwe-ultraviolet kube yi-fluorescence ebonakalayo. Wathola nokuthi ubumhlophe bemicu yemvelo bungathuthukiswa ngokuyiphatha ngesisombululo samanzi sento e-fluorescent. Ngo-1929, uKrais wasebenzisa isimiso sikaLagorio ukufakazela ukuthi i-rayon ephuzi yayicwiliswe kusisombululo se-6, 7-dihydroxycoumarin glycosyl. Ngemva kokomiswa, kwatholakala ukuthi ubumhlophe be-rayon buthuthuke kakhulu.
Ukuthuthukiswa okusheshayo kwama-fluorescent brighteners kuholele abanye abantu ekuzibekeni ezingeni elifanayo nokufika kwama-reactive dyes kanye nama-organic pigment DPP njengezinto ezintathu ezifezwe kakhulu embonini yamadayi ngasekupheleni kwekhulu lama-20.
Izimboni eziningi seziqalile ukusebenzisa izibani ezikhanyisa ukukhanya, njengephepha, ipulasitiki, isikhumba, insipho. Ngesikhathi esifanayo emikhakheni eminingi yobuchwepheshe obuphezulu, ukusetshenziswa kwe-ejenti yokwenza mhlophe ekhanyayo, njenge: ukutholwa kwe-fluorescence, i-dye laser, ukuphrinta okulwa nokukhwabanisa, njll., ngisho nezithombe eziphakeme kakhulu ezinefilimu yokuzwela okuphezulu ukuthuthukisa ukuzwela kwe-latex yezithombe, kuzophinde kusetshenziswe i-ejenti yokwenza mhlophe ekhanyayo.

iphakheji kanye nokuthuthwa

B. Lo mkhiqizo ungasetshenziswa,,25KG，200KG,1000KGBAERRLS。
C. Gcina kuvaliwe endaweni epholile, eyomile futhi enomoya opholile ngaphakathi. Izitsha kufanele zivalwe kahle ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthuthwa ukuze kuvinjelwe umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
