E kamaʻilio e pili ana i ka noi ohexagonal nano boron nitridema ke kahua hoʻomaʻemaʻe

1. Pono o hexagonal boron nitride nanoparticles i loko o ka cosmetic kahua

Ma ke kahua hoʻomaʻemaʻe, pili pono ka pono a me ka permeability o ka mea hana i loko o ka ʻili i ka nui o ka ʻili, a he mea nui ka nui o ka mea hoʻonaninani no ka mea hiki ke hoʻonui ʻia ka ʻili o nā ʻāpana liʻiliʻi a hiki ke hoʻopili i ka mea hoʻonaninani.Hiki i ka hexagonal boron nitride (h-BN) nanomaterial ke hoʻomalu i ka nui o nā ʻāpana hui.Hexagonal boron nitride loaʻa nā pōmaikaʻi i nā mea hoʻonaninani, ʻoi aku ka nui o nā huahana pale lā, e hiki ai i nā nanostructure ke hoʻomalu ʻia ma nā pae like ʻole o ka hoʻokumu ʻana e hoʻomalu i ka nui a me ka ʻili;a loaʻa iā ia nā waiwai maikaʻi loa i ka dispersion, non-toxic, transparency a me ka chemically inert.

2. ʻO ka noiʻi ʻana i ka pale ʻana i ka lā infrared radiation o Nano Boron Nitride

Ua ʻike ʻia he hiki ke hōʻino i ke olakino o ka ʻili o ka lā.ʻO ka laulā o ka ikehu lā e piʻi maʻamau i ka ʻili o ka honua he ultraviolet a me ka infrared.ʻO nā hopena o ke kukui UV he mea pōʻino i ke olakino ʻili a hiki ke hopena i ka piʻi ʻana o ka maʻi kanesa, ka ʻelemakule a me nā hoʻololi ʻē aʻe i makemake ʻole ʻia, a pane i ka sunburn, erythema a me ka mumū.Hoʻonui nā kukuna infrared i ka pōʻino a me ka wā kahiko o nā kukuna ultraviolet i ka ʻili, a loaʻa paha i ka radiation infrared i ka photocarcinogenesis.

Ua lōʻihi ka noiʻi ʻana o ka ʻoihana hoʻonaninani i nā huahana pale lā.Ua hoʻomohala ʻia nā sunscreens me ka hoʻohana ʻana i ka nanoscience a me ka ʻike nanotechnology, e like me ka nano titanium dioxide, kahi mea hoʻonaninani koʻikoʻi no nā kukuna UV pale.Eia nō naʻe, no ka pale ʻana i ka radiation infrared, he liʻiliʻi loa nā haʻawina sunscreen, a ma kēia ʻano, pono e hana i nā sunscreens e hāʻawi ai i ka pale UV a me IR.ʻO nā nanopowders Boron nitride nā mea hiki ke hoʻomalu i ka nui o nā mea i hoʻohui ʻia, kahi mea nui i ka hoʻohana ʻana i nā pale lā.Hoʻemi ia i ka luster o ka ʻili ʻaila ma muli o kāna conductivity thermal kiʻekiʻe.ʻO ka Titanium dioxide nanoparticles i loaʻa i ka nanostructured boron nitride kahi hui kūpono i hiki ke hoʻohana ʻia i mea hoʻonaninani e pale aku i ke kino mai ka radiation infrared o ka lā.

ʻOiaʻiʻo, ʻo ka hoʻohana ʻana i nā nanoparticles boron nitride hexagonal i ke kahua o nā mea hoʻonaninani ʻaʻole wale ka sunscreen.Nui ka waiwai o nā ʻano mea hoʻonaninani.Ma waho aʻe o nā mea hoʻonaninani, ʻoi aku ka nui o ka hoʻohana ʻana i nā ʻāpana ʻē aʻe o ka hexagonal boron nitride nanoparticles, a hiki ke hoʻopili ʻia i ka hana seramika, e like me ka crucible, nā waʻa evaporation aluminika, nā substrates circuit board a me nā lubricants kiʻekiʻe, hoʻohana ʻia e like me nā mea hana. no ka nuklea reactors a me ka rocket engine units.
