ʻO kahi poho nui maikaʻi loa maikaʻi loa

I nā makahiki i hala aku nei i nā mea i hala no ka pono o ka palekana UVAke hoʻonui nei i ka wikiwiki.

ʻO Uv radiation maikaʻi nā hopena maikaʻi loa, e komo pū me Sunburn, kiʻi-ka'ōpū a me nā maʻi maʻi. Hiki ke paleʻia kēia mau hopena ma ka paleʻana i ka paleʻana i kaʻaoʻao holoʻokoʻa o ka radiation UV e komo pū me Uva.

Ma kaʻaoʻao'ē aʻe heʻano likeʻole e palena i ka nui o nā "cmoticals" ma kaʻili. ʻO kēia keʻano o ka maikaʻi loa o UV Abso Abso AbsoNā 'ōkuhipono e loaʻa no ka koi hou o ka pale ākea o UV.SunSafe-BMTZ(BIS-BIS-EthylhexySaxylFexnol MethoxyAny i hoʻolālāʻia e hoʻokō i kēia koi. ʻO ia ke kiʻi-stable, aila-momona, kūpono a uhiʻia i ka UVB a me UVA RAX. I ka makahiki 2000, ua hoʻohuiʻia nā luna eurou'Elani iā ​​Bis-ethylhexySloxyLoxHinfhehanpyols ma ka papa inoa o nā cosometic uv acbsorber.

•Uva:Pono nā hui ortho-Ohho-Ohball no ka weheʻana i ka ikaika o ka ikehu ma o nā ala hydrogen intramolecular hydrovergen. No ka loaʻaʻana o ka absorption ikaika ma ka UVA, e kohoʻia nā kūlana o nā mila o nā mhenyl phenyl e-alycil

•UVB:ʻO keʻano o ka hui phenyl phenyl i hoʻopiliʻia e pili ana i ka triazine alakaʻi iā UVB e pili ana. Hiki ke hōʻikeʻia i kēlā meximal "piha piha" e hoʻokō me ka hana me-alkyl aia i loko o ke kūlana para-kūlana. Me ka hoʻoponoponoʻoleʻana i nā mea i koiʻia, he nui nā helu i loko o nā ailaʻaila. Hōʻike lākou i nā waiwai maʻamau o nā puaʻa I mea e hoʻonui ai i ka lako i kaʻaila o ka aila, ua loli like keʻano o ka uv kānana.
