ngā āhuatanga matū

E ai ki te hanganga matū, e rima ngā wāhanga e taea te wehewehe:
1, momo stilbene: whakamahia mō te muka miro me ētahi muka hangai, te hanga pepa, te hopi me ētahi atu ahumahi, me te kanapa kikorangi;
2, momo coumarin: he hanganga taketake coumarin, e whakamahia ana mō te celluloid, te kirihou PVC, me te kaha o te hihi kikorangi;
3, momo pyrazoline: whakamahia mō te huruhuru hipi, te polyamide, te muka kiriaku me ētahi atu muka, me te tae matomato kanapa;
4, momo hauota benzoxy: whakamahia mō ngā muka kiriaku me te polyvinyl chloride, polystyrene me ētahi atu kirihou, me te fluorescence whero;
5, momo benzoimide e whakamahia ana mō te polyester, te kiriaku, te nairona me ētahi atu muka, me te fluorescence kikorangi.

Te whakataki me ngā āhuatanga o te hua

Ko te rama whakamārama (rama whakamārama) he tae rama, he tae mā rānei, he kupu whānui hoki mō tētahi rōpū matū. Ko tōna āhuatanga he kaha ki te whakaoho i te mārama e pā mai ana hei whakaputa i te rama, kia rite ai te pānga o te rauemi poke ki te kanapa rama, kia kitea ai e te kanohi tahanga he tino mā te rauemi.

whakamahi

I te tau 1852 i puta te whakamārama ariā tuatahi mō te fluorescence, i te wā i whakaarohia ai e Stokes te mea i mōhiotia ko te Ture a Stokes. I te tau 1921 i kite a Lagorio he iti iho te kaha fluorescence kitea e tukuna ana e ngā tae fluorescent i te kaha mārama kitea e mimitihia ana e rātou. Nā konei, i whakatau ia he kaha ngā tae fluorescent ki te huri i te mārama ultraviolet kore e kitea hei fluorescence kitea. I kitea anō e ia ka taea te whakapai ake i te mā o ngā muka taiao mā te rongoā i a rātou ki te wairewa o te matū fluorescent. I te tau 1929, i whakamahia e Krais te mātāpono a Lagorio hei whakaatu i te rumakina o te rayon kōwhai ki roto i te wairewa o te 6, 7-dihydroxycoumarin glycosyl. I muri i te whakamaroke, i kitea kua tino pai ake te mā o te rayon.
Nā te tere o te whanaketanga o ngā whakakanapa rama hihiko, kua whakaarohia e ētahi ngā whakatutukitanga nui e toru o te umanga tae i te mutunga o te rautau 20, me te taenga mai o ngā tae tauhohe me ngā tae rauropi DPP.
He maha ngā ahumahi kua tīmata ki te whakamahi i ngā mea whakamārama kanapa, pērā i te pepa, te kirihou, te hiako, me te hopi horoi. I taua wā anō, i roto i ngā mara hangarau teitei maha, ka whakamahia anō hoki ngā mea whakamārama kanapa, pērā i te: kimi kanapa, tae taiaho, tānga ārai-rūpahu, me ētahi atu, tae atu ki te whakaahua teitei me te kiriata tairongo teitei hei whakapai ake i te tairongo o te rapa whakaahua, ka whakamahia anō hoki ngā mea whakamārama kanapa.
