ʻO ka mea hana keʻokeʻo Fluorescent kahi ʻano mea hoʻohuihui e hiki ke hoʻomaikaʻi i ke keʻokeʻo o nā lole fiber a me ka pepa, i ʻike ʻia hoʻi he mea keʻokeʻo optical a me ka mea keʻokeʻo fluorescent.He melemele nā lole, a me nā mea ʻē aʻe ma muli o ka hoʻokomo ʻia ʻana o nā haumia kala, a ua hoʻohana ʻia ka bleaching kemika e decolorize iā lākou i ka wā ma mua.Hoʻohana ʻia ke ʻano o ka hoʻohui ʻana i kahi mea keʻokeʻo i ka huahana, a ʻo kāna hana ʻo ia ka hoʻohuli ʻana i ka radiation ultraviolet i ʻike ʻole ʻia e ka huahana i loko o ka radiation fluorescent blue-violet, i hoʻohui ʻia i ka radiation kukui melemele kumu a lilo i kukui keʻokeʻo. hoʻomaikaʻi i ka hiki o ka huahana ke kū i ka lā.o keokeo.Ua hoʻohana nui ʻia nā brighteners i nā textiles, ka pepa, ka pauka holoi, ke kopa, ka pulupulu, ka plastics, ka puaʻa a me ka pena.
Loaʻa i nā mea hoʻomālamalama nā ʻōnaehana cyclic conjugated i loko o ke ʻano kemika, e like me: stilbene derivatives, phenylpyrazoline derivatives, benzothiazole derivatives, benzimidazole derivatives, coumarin derivatives a me Naphthalimide derivatives, etc., ma waena o nā derivatives stilbene ka nui o nā hua.E hoʻohana i nā ʻano a me nā waiwai no ka hoʻokaʻawale ʻana i nā kukui hiki ke hoʻokaʻawale ʻia i ʻehā ʻano:
ʻO kahi moʻo e pili ana i nā mea keʻokeʻo fluorescent hiki ke hoʻohua i nā cations i ka wai.He kūpono no ka hoʻomaʻemaʻe ʻana i nā fibers acrylic.He kūpono nā mea hoʻomālamalama uila B series no ka hoʻomālamalama ʻana i nā fiber cellulose.C moʻo e pili ana i kekahi 'ano o ka fluorescent whitening agent hoopuehu i loko o ka waiʻauʻau 'auʻau i mua o ka dispersant, kūpono no ka whitening polyester a me kekahi hydrophobic fibers.ʻO ka moʻo D e pili ana i ka mea keʻokeʻo fluorescent kūpono no ka fiber protein a me ka nylon.E like me ka hoʻolālā kemika, hiki ke hoʻokaʻawale ʻia nā mea keʻokeʻo i ʻelima mau ʻāpana: ① ʻano stilbene, hoʻohana ʻia i loko o ka pulupulu pulupulu a me kekahi mau synthetic fibers, pepa, hana kopa a me nā ʻoihana ʻē aʻe, me ka fluorescence polū;② ʻano coumarin, me ka ʻala ʻO ke ʻano kumu o ka bean ketone, i hoʻohana ʻia i nā plastic polyvinyl chloride, etc., he fluorescence polū ikaika;③ ʻano pyrazoline, hoʻohana ʻia no ka hulu hipa, polyamide, nā fibers acrylic a me nā fibers ʻē aʻe, me ka fluorescence ʻōmaʻomaʻo;④ ʻano benzoxazine, me No nā fibers acrylic a me nā plastics ʻē aʻe e like me ka polyvinyl chloride a me ka polystyrene, loaʻa iā ia ka fluorescence ʻulaʻula;⑤phthalimide ʻano, no ka polyester, acrylic, nylon a me nā fibers ʻē aʻe, me ka fluorescence polū.ʻO ka mea i luna nei ka hoʻokaʻawale ʻana o nā mea keʻokeʻo.Ke koho nā mea kūʻai aku i nā mea hana keʻokeʻo, pono lākou e hoʻomaopopo mua i kā lākou huahana ponoʻī, i hiki iā lākou ke koho i ka mea keʻokeʻo pono.A pono e ʻike nā mea kūʻai aku i ka wā e hoʻohana ai i nā mea hoʻomaʻemaʻe keʻokeʻo, ʻo nā mea keʻokeʻo keʻokeʻo wale nō ka hoʻomālamalama ʻana a me nā kala hoʻohui, ʻaʻole hiki ke hoʻololi i ka bleaching kemika.No laila, mālama pono ʻia ka mea kala me kahi mea keʻokeʻo me ka ʻole o ka bleaching, a ʻaʻole hiki ke loaʻa i ka hopena keʻokeʻo.Aʻo ka mea keʻokeʻo keʻokeʻo ʻaʻole ia he keʻokeʻo, akā loaʻa kekahi ʻano saturation.ʻOi aku i kahi waiwai palena paʻa, ʻaʻole wale ka hopena keʻokeʻo, akā melemele hoʻi.
