Njira Yopangira
Adipic acid ndi thionyl chloride adasakanizidwa mu chiŵerengero cha kulemera kwa 1: (6-10) ndi refluxed kwa 20-60 h pamaso pa chothandizira pyridine.The zosungunulira anali chamunthuyo ndi zotsalira unatenthedwa pa 140-160 ℃ kwa 3-7 H. Thiophene-2,5-dicarboxylic asidi analandira ndi sodium hydroxide mankhwala, mpweya mpweya, kusefera, decolorization ndi kuyeretsedwa.
Kugwiritsa ntchito
Fulorosenti whitening wothandizira EBF anakonzedwa ndi condensation wa mankhwala ndi o-aminophenol.Chowunikirachi chingagwiritsidwe ntchito pa nayiloni, poliyesitala, polypropylene, chloro ndi triacetic acid.Ndi mankhwala okhala ndi zinthu zabwino kwambiri.Amagwiritsidwa ntchito pokonzekera fulorosenti whitening wothandizira, makamaka ntchito whitening wa kupanga CHIKWANGWANI, Eva, PVC, pulasitiki ndi mphira, ndipo angagwiritsidwe ntchito whitening wa filimu pulasitiki, psinjika akamaumba zipangizo, jekeseni akamaumba zipangizo, etc.
Kusungirako
Losindikizidwa sitolo mu mpweya wokwanira ndi malo ouma ndi kutali ndi kuwala.
