Metotia Gaosiga
O le adipic acid ma le thionyl chloride na faʻafefiloi i le fua o le mamafa o le 1: (6-10) ma faʻafefe mo le 20-60 h i luma o le pyridine catalyst.O le solvent na faʻamama ma faʻamafanafanaina le toega i le 140-160 ℃ mo le 3-7 H. Thiophene-2,5-dicarboxylic acid na maua e le sodium hydroxide treatment, acid precipitation, filtration, decolorization ma le faʻamamaina.
Fa'atatauga
O le faʻamalama paʻepaʻe EBF na saunia e ala i le condensation o le oloa ma le o-aminophenol.E mafai ona fa'aogaina lenei fa'amalama mo nailo, polyester, polypropylene, chloro ma triacetic acid fibers.O se oloa e iai mea e sili ona lelei.E masani ona faʻaaogaina i le sauniuniga o le fluorescent whitening agent, e masani ona faʻaaogaina i le paʻepaʻe o fibre gaosia, EVA, PVC, palasitika ma le paʻu, ma e mafai ona faʻaaogaina i le paʻepaʻe o ata palasitika, mea faʻapipiʻi faʻamalosi, mea faʻapipiʻi tui, ma isi.
Teuina
Faamaufa'ailoga faleoloa i se nofoaga malulu ma fa'amamago ma taumamao mai le malamalama.
