ʻano kemika

Wahi a ko lākou ʻano kemika, hiki ke hoʻokaʻawale ʻia i ʻelima mau ʻāpana:
1, ʻano stilbene: hoʻohana ʻia no ka pulupulu pulupulu a me kekahi mau synthetic fibers, pepa, kopa a me nā ʻoihana ʻē aʻe, me ka fluorescence polū;
2, ʻano coumarin: me ka coumarin kumu kumu, hoʻohana ʻia no celluloid, PVC plastic, me ka fluorescence polū ikaika;
3, ʻano pyrazoline: hoʻohana ʻia no ka hulu hipa, polyamide, acrylic fiber a me nā fibers ʻē aʻe, me ka waihoʻoluʻu fluorescent ʻōmaʻomaʻo;
4, benzoxy nitrogen type: hoʻohana ʻia no nā fibers acrylic a me polyvinyl chloride, polystyrene a me nā plastics ʻē aʻe, me ka fluorescence ʻulaʻula;
5, hoʻohana ʻia ke ʻano benzoimide no ka polyester, acrylic, nylon a me nā fibers ʻē aʻe, me ka fluorescence polū.

Hoʻopuka huahana a me nā hiʻohiʻona

ʻO ka mea hoʻonani ʻālohilohi (fluorescent brightener) he mea hoʻolāʻau fluorescent, a i ʻole keʻokeʻo keʻokeʻo, ʻo ia hoʻi ka huaʻōlelo maʻamau no ka hui pūhui.ʻO kona waiwai ka mea hiki ke hoʻoulu i ka mālamalama hanana e hana i ka fluorescence, i like ka hopena o ka mea i hoʻohaumia i ka fluorite glitter, i ʻike ka maka ʻōlohelohe i ka mea keʻokeʻo.

hoʻohana

ʻO ka wehewehe mua ʻana o ka fluorescence i hele mai i ka makahiki 1852, i ka manawa i noi ai ʻo Stokes i ka mea i kapa ʻia ʻo Stokes' Law.I ka makahiki 1921, ua ʻike ʻo Lagorio, ʻoi aku ka haʻahaʻa o ka ikehu fluorescence ʻike ʻia i hoʻokuʻu ʻia e nā mea hoʻonaninani fluorescent ma mua o ka ikehu māmā ʻike ʻia e lākou.No kēia kumu, ua hoʻoholo ʻo ia i ka hiki ke hoʻololi i ke kukui ultraviolet ʻike ʻole ʻia i loko o ka fluorescent dyes.Ua ʻike pū ʻo ia e hiki ke hoʻomaikaʻi ʻia ke keʻokeʻo o nā fiber maoli ma o ka mālama ʻana iā lākou me kahi wai wai o kahi mea fluorescent.I ka makahiki 1929, ua hoʻohana ʻo Krais i ka manaʻo o Lagorio e hōʻoiaʻiʻo ua hoʻokomo ʻia ka rayon melemele i loko o kahi hopena o 6, 7-dihydroxycoumarin glycosyl.Ma hope o ka maloʻo ʻana, ua ʻike ʻia ua hoʻomaikaʻi nui ʻia ka keʻokeʻo o ka rayon.
ʻO ka hoʻomohala wikiwiki ʻana o nā mea hoʻomālamalama fluorescent ua alakaʻi i kekahi poʻe e hoʻonohonoho iā lākou me ka hiki ʻana mai o nā mea hoʻonaninani reactive a me nā puaʻa organik DPP ma ke ʻano he ʻekolu mau hoʻokō nui i ka ʻoihana wai i ka hopena o ke kenekulia 20.
Ua hoʻomaka ka nui o nā ʻoihana e hoʻohana i nā mea hoʻomālamalama fluorescent, e like me ka pepa, ka plastic, ka ʻili, ka mea holoi.I ka manawa like i nā kula kiʻekiʻe kiʻekiʻe hoʻi i ka hoʻohana ʻana i ka mea hana keʻokeʻo fluorescent, e like me: fluorescence detection, dye laser, anti-counterfeit printing, etc., a hiki i ke kiʻi kiʻekiʻe kiʻekiʻe me ke kiʻi ʻoniʻoni kiʻekiʻe e hoʻomaikaʻi i ka ʻike. o ka latex paʻi kiʻi, e hoʻohana hoʻi i ka mea hana keokeo fluorescent.

pūʻolo a me ka lawe ʻana

B. Hiki ke hoʻohana ʻia kēia huahana, 25KG, 200KG, 1000KGBAERRLS.
C. E kūʻai i sila ma kahi anuanu, maloʻo a me ka makani ma loko.Pono e hoʻopaʻa paʻa ʻia nā pahu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa maikaʻi ʻia kēia huahana i ka wā o ka lawe ʻana e pale aku i ka makū, ka alkali ikaika a me ka waikawa, ka ua a me nā mea haumia ʻē aʻe mai ka hui ʻana.
