Hoʻopili ka pauka fluorescent UV ma lalo o nā kukuna ultraviolet. He nui nā noi ʻana o ka pauka fluorescent UV, ʻo nā noi nui i ka anti-counterfeiting inks a i kēia manawa pū kekahi i ka mahele ʻano.

I loko o kahi au i piha i nā huahana hoʻopunipuni, ua lilo ka ʻenehana anti-fraud i mea koʻikoʻi no ka pale ʻana i ka brand.ʻO Topwell Chem'sʻO 365nm Organic UV Red Fluorescent Pigment, me kāna "ʻike ʻole a ʻike ʻia, e wehewehe hou ana i nā noi inika palekana.

1. ʻO nā ʻāpana ʻulaʻula o UV: Nā Code Palekana Optical

ʻIke ʻia ma lalo o ke ao akā e hoʻopuka ana i ka ʻulaʻula ʻulaʻula ma lalo o ke kukui UV 365nm (Ex 365nm/Em 610-630nm), hiki i kēia "inky invisible":

• Palekana Banknote-grade: Hoʻohana ʻia i ka paʻi kālā ma ka honua holoʻokoʻa
• ʻO ka hōʻoia ʻana o ka pūʻulu: nā māka huna no ka hoʻopili waiwai / lāʻau lapaʻau
• Hoʻopili palapala: Unclonable fluorescent tag ma nā palapala hōʻoia

• 2. Kekahi ʻenehana

  1. Paʻa Paʻa Organic Formula
     ʻO ka dispersibility kiʻekiʻe a me nā puaʻa anorganic e hōʻoia i ka paʻi like ʻole me ka ʻole o ka sedimentation.
  2. Loʻihi hawewe pololei
     Hāʻawi ka 610-630nm ʻulaʻula i ka hiʻohiʻona kiʻekiʻe, kākoʻo i nā hui like ʻole (e laʻa me ka ʻulaʻula + ʻōmaʻomaʻo) no ka palekana papa.
  3. Kū'ē Kūlohelohe
     E mālama i ka ikaika o ka fluorescence ma lalo o ka haʻahaʻa/uv exposure, e like me nā kūlana ISO 2835.

  3. Nā mea hoʻohana hou

  • FMCG: ʻO nā code palekana UV ma nā pāpale omole i hōʻoia ʻia e nā kukui UV atamai
  • Electronics: ʻO nā hōʻailona hōʻailona Fluorescent ma nā papa PCB
  • Nā mea hōʻiliʻili: ʻōnaehana helu huna no nā kāleka paʻi palena ʻole
  • 4. No ke aha he mea nui nā mea hoʻolako ʻoihana
  • Hōʻoia ka ʻike o Topwell Chem:
    • Ka Mana Māmā (D50≤5μm) no ka paʻi ʻana kiʻekiʻe
    • Halawai ʻōhumu metala kaumaha ʻole REACH
    • Nā mea hoʻoponopono kūʻokoʻa no nā pono kūʻē i ka hoʻopunipuni
