He Kānana UV ʻĀpana Laulā Loa Loa

I nā makahiki he ʻumi i hala iho nei, ʻo ka pono no ka pale ʻana i ka UVA i hoʻomaikaʻi ʻiaua piʻi wikiwiki.

He mau hopena maikaʻi ʻole ka radiation UV, me ka ʻā ʻana o ka lā, ke kiʻi-ka ʻelemakule a me ke kanesa ʻili. Hiki ke pale ʻia kēia mau hopena ma ka pale ʻana i nā kukuna UV āpau, me ka UVA.

Ma ka ʻaoʻao ʻē aʻe, aia kekahi ʻano e kaupalena i ka nui o nā "kemika" ma ka ʻili. ʻO ke ʻano kēia he mea kūpono loa ka abso UVnā mea hoʻolelepono e loaʻa no ke koi hou o ka palekana UV ākea.Sunsafe-BMTZ（Ua hoʻolālā ʻia ʻo Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine e hoʻokō i kēia koi. He paʻa ia i ke kiʻi, hoʻoheheʻe ʻia i ka ʻaila, kūpono loa a uhi i ka laulā UVB a me UVA. I ka makahiki 2000, ua hoʻohui nā luna ʻEulopa iā Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine i ka papa inoa maikaʻi o nā mea hoʻomoʻa UV hoʻonaninani.

•UVA:Pono ʻelua mau hui ortho-OH no ka hoʻolaha ʻana o ka ikehu ma o nā alahaka hydrogen intramolecular. I mea e loaʻa ai ka omo ikaika i ka UVA, pono e pani ʻia nā kūlana para o nā ʻāpana phenyl ʻelua e O-alkyl, e hopena ana i kahi bis-resorcinyl triazine chromophor.

•UVB:ʻO ke koena o ka hui phenyl i hoʻopili ʻia i ka triazine e alakaʻi i ka omo ʻana o ka UVB. Hiki ke hōʻike ʻia ua hoʻokō ʻia ka hana "full spectrum" kiʻekiʻe loa me O-alkyl i loaʻa ma ke kūlana para. Me ka ʻole o nā mea hoʻohui solubilizing, aneane hiki ʻole ke hoʻoheheʻe ʻia nā HPT i nā aila hoʻonaninani. Hōʻike lākou i nā ʻano maʻamau o nā pigments (e laʻa, nā kiko heheʻe kiʻekiʻe). I mea e hoʻonui ai i ka solubility i nā pae aila, ua hoʻololi ʻia ke ʻano o ka kānana UV e like me ia.

Nā Pōmaikaʻi:

Ka palekana lā ākea

Hoʻohālikelike loa ʻia me nā kānana UV ʻē aʻe

Paʻa o ke ʻano hana
