Nano Titanium Dixoide Powder TiO2 Nanoparticle no ka Ultraviolet-hōʻike

Hoʻolauna o Titanium Dioxide Nanopowder:

Nui ʻāpana: 10nm, 30-50nm

Maʻemaʻe: 99.9%

ʻO ke ʻano kristal: anatase, rutile

Nānā: keʻokeʻo

Hana ʻo Nano TiO2 no ka anti-ultraviolet:Hiki i ka Nano-TiO2 ke komo i nā kukui ultraviolet ʻelua, akā e noʻonoʻo hoʻi, hoʻopuehu ʻia ke kukui ultraviolet, akā ma o ke kukui ʻike ʻia, ʻoi aku ka maikaʻi o ka hana, ʻoi loa ka hoʻohiki ʻana i ke ʻano pale pale UV.

Nano-titanium dioxide anti-ultraviolet mechanical: E like me nā hawewe ʻokoʻa, ua māhele ʻia ka ultraviolet i nā wahi pōkole pōkole 190 ~ 280 nm, wahi hawewe waena 280 ~ 320 nm, wahi nalu lōʻihi 320 ~ 400nm.

ʻO ka wahi hawewe pōkole ka ikehu ultraviolet kiʻekiʻe loa, akā ua paʻa ʻia ke hoʻokaʻawale ʻia mai ka papa ozone.No laila, ʻo ka pōʻino i ke kino o ke kanaka, aia ma waena a me nā wahi lōʻihi o ka nalu.ʻO ke kūpaʻa UV ikaika o ka nano-titanium dioxide ma muli o kāna hana refractive kiʻekiʻe a me ka māmā kiʻekiʻe.ʻO kona hiki ke anti-ultraviolet a me kāna hana e pili ana i kona nui.

Ke nui ka nui o ka ʻāpana, ʻike ʻia ka pale i nā kukuna ultraviolet a hoʻopuehu ʻia, a he kūpono ia no nā ultraviolet a me nā hawewe waena.He uhi maʻalahi ka mīkini pale lā, he pale kino kino, nāwaliwali ka pale lā;me ka emi ana o ka nui, hiki i ka malamalama ke hele ma ka nano-titanium dioxide particle surface, ka nalu lōʻihi o ka ultraviolet light reflection, ʻaʻole maopopo ka hoʻopuehu ʻana, a ʻike ʻia ka hoʻonui ʻia ʻana o ke kukui ultraviolet ma ka wahi nalu.

ʻO ka mīkini pale lā e hoʻomoʻi i ka kukui ultraviolet, ka mea nui o ka hoʻopili ʻana o ke kukui ultraviolet ma ka wahi nalu. poloka i ka hoʻopuehu nui, ʻo ka nalu UV ma ka ʻāpana nalu e hoʻomoʻa i ka mea nui.

Ua hōʻike ka Nano-titanium dioxide i nā hawewe like ʻole i nā waiwai absorption maikaʻi loa, i ka hoʻohālikelike ʻia me nā sunscreen organik ʻē aʻe, nano-titanium dioxide me ka hana ʻole, ka hana paʻa, ka hopena maikaʻi a pēlā aku. ʻO nā kukui ultraviolet i hoʻopuehu ʻia, akā e komo pū i ke kukui ultraviolet, ʻoi aku ka ikaika o ka pale ʻana iā UV.

Ke hoʻohālikelike ʻia me kekahi o nā ʻano like o ka mea hoʻomalu UV kūlohelohe, HWNANO nano-titanium dioxide i ka ultraviolet absorption peak kiʻekiʻe, ʻoi aku ka waiwai he ākea ākea o nā mea pale, ʻaʻole like me ka mea hoʻomalu UV kūlohelohe i hoʻokahi UVA a i ʻole UVB absorption.
