ʻElima nanopowders—mea pale electromagnetic maʻamau

I kēia manawa, ʻo ka mea i hoʻohana nui ʻia he composite electromagnetic shielding coatings, ʻo ia ka mea nui o ka resin-forming film, conductive filler, diluent, coupling agent a me nā mea hoʻohui ʻē aʻe.I waena o lākou, he mea nui ka hoʻopiha conductive.ʻO ka pauka kālā a me ka pauka keleawe, ka pauka nickel, ka pauka keleawe i uhi ʻia i ke kālā, nā nanotubes carbon, graphene, nano ATO a pēlā aku.

1.Nanotube kalapona

Loaʻa i ka carbon nanotubes i ka ratio hiʻona maikaʻi a me nā waiwai uila a me nā waiwai magnetic, a hōʻike i ka hana maikaʻi loa i ka uila a me ka pale ʻana.No laila, pili ka hoʻonui nui ʻana i ka noiʻi a me ka hoʻomohala ʻana i nā hoʻopiha conductive e like me nā pale pale electromagnetic.Loaʻa kēia i nā koi kiʻekiʻe e pili ana i ka maʻemaʻe, ka huahana a me ke kumukūʻai o carbon nanotubes.ʻO nā nanotubes kalapona i hana ʻia e Hongwu Nano Factory, me nā CNTs hoʻokahi-pā a me nā pā lehulehu, he maʻemaʻe a hiki i ka 99%.ʻO ka hoʻopuehu ʻana o nā nanotubes kalapona i loko o ka resin matrix a inā he pilina maikaʻi me ka resin matrix e lilo i kumu kūpono e pili ana i ka hana pale.Hāʻawi pū ʻo Hongwu Nano i kahi hopena dispersion carbon nanotube.

2. Haʻahaʻa Bulk Density a haʻahaʻa SSApauda kala kala

Ua hoʻopaʻa ʻia nā ʻāpana conductive mua loa i loaʻa i ka lehulehu ma ʻAmelika Hui Pū ʻIa i ka makahiki 1948 e hana i nā mea hoʻopili conductive i hana ʻia me ke kālā a me ka epoxy.ʻO ka peʻa pale electromagnetic i hoʻomākaukau ʻia e ka pauka kālā i hana ʻia e Hongwu Nano nā hiʻohiʻona o ke kūpaʻa uila liʻiliʻi, ka conductivity uila maikaʻi, ka hana pale pale kiʻekiʻe, ke kūpaʻa kūwaho ikaika a me ka hana maʻalahi.Hoʻohana nui ʻia i nā kamaʻilio, nā uila, nā lāʻau lapaʻau, nā aerospace, nā hale nuklea a me nā ʻano ʻē aʻe o ka pena pale e kūpono hoʻi no ABS, PC, ABS-PCPS a me nā ʻenekini ʻenehana i uhi ʻia.ʻO nā hōʻailona hana e pili ana i ke kūpaʻa ʻaʻahu, ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ka pale ʻana i ka wela a me ka haʻahaʻa, ka adhesion, ka pale uila, a me ka hoʻohālikelike electromagnetic.

3. Pauda keleaweapauda nikela

He haʻahaʻa ke kumukūʻai o ka pauka keleawe, maʻalahi ke hoʻopili, loaʻa ka hopena pale electromagnetic maikaʻi, a hoʻohana nui ʻia.Ua kūpono loa lākou no ka hoʻopili ʻana i ka nalu electromagnetic o nā huahana uila me nā plastics ʻenekinia e like me ka pūpū, no ka mea, hiki ke hoʻomaʻamaʻa maikaʻi ʻia ka peʻa keleawe pauka conductive a palaki ʻia ma nā ʻano like ʻole o ka plastic i hoʻohana ʻia e hana i ka ʻili, a ua hoʻoheheʻe ʻia ka ʻili plastik e hana i kahi electromagnetic shielding conductive layer, i hiki i ka plastic ke hoʻokō i ke kumu o ka pale ʻana i nā nalu electromagnetic.ʻO ke ʻano a me ka nui o ka pauka keleawe he mana nui i ka conductivity o ka uhi.He ʻano spherical ka pauka keleawe, he ʻano dendritic, he ʻano pepa a me nā mea like.ʻOi aku ka nui o ka pepa ma mua o ka wahi pili spherical a hōʻike i ka conductivity ʻoi aku ka maikaʻi.Eia kekahi, ua uhi ʻia ka pauka keleawe (ka pauka keleawe i uhi ʻia) me ka pauka kālā metala ʻole, ʻaʻole maʻalahi ke hoʻoheheʻe ʻia.ʻO ka maʻamau, ʻo ka ʻike kālā he 5-30%.Hoʻohana ʻia ka pale keleawe keleawe e hoʻoponopono i ka pale electromagnetic o nā plastic engineering a me ka lāʻau e like me ABS, PPO, PS, etc.

Eia kekahi, ʻo ka hopena o ke ana ʻana i nā hopena electromagnetic shielding coatings i hui pū ʻia me ka pauka nano-nickel a me ka pauka nano-nickel a me ka pauka micro-nickel e hōʻike ana i ka hoʻohui ʻana o ka pauka nano-nickel hiki ke hōʻemi i ka pono pale electromagnetic, akā hiki ke hoʻonui i ka pono. lilo o ka absorption ma muli o ka hoonui.Hoʻemi ka tangent nalowale magnetic i ka pōʻino i hoʻokumu ʻia e nā hawewe electromagnetic i ke kaiapuni a me nā mea hana a me ka pōʻino i ke olakino kanaka.

4. NanoATOTin Oxide

Ma ke ʻano he mea hoʻopihapiha kū hoʻokahi, ʻo ka pauka nano-ATO he kiʻekiʻe a me ka conductivity, a he mau noi ākea i ka hōʻike ʻana i nā mea uhi uhi, conductive antistatic coatings, transparent thermal insulation coatings a me nā kahua ʻē aʻe.Ma waena o nā mea pale optoelectronic e hōʻike ana i nā mea hoʻopili, loaʻa nā mea ATO i nā hana anti-static, anti-glare a me anti-radiation, a ua hoʻohana mua ʻia e like me nā mea pale pale electromagnetic no nā hōʻike.Loaʻa i nā mea hoʻopili ʻo Nano ATO i ke aniani kala māmā, ka conductivity uila maikaʻi, ka ikaika mechanical a me ke kūpaʻa.ʻO ia kekahi o nā noi ʻoihana koʻikoʻi o nā mea ATO i nā lako hōʻike.ʻO nā hāmeʻa electrochromic, e like me nā hōʻike a i ʻole nā ​​puka makani akamai, he ʻano koʻikoʻi o nā noi nano ATO i kēia manawa ma ke kahua hōʻike.

5. Graphene

Ma ke ʻano he mea kalapona hou, ʻoi aku ka nui o ka graphene i mea pale electromagnetic maikaʻi hou a i ʻole nā ​​​​mea hoʻoheheʻe microwave ma mua o carbon nanotubes.ʻO nā kumu nui e like me kēia:

ʻO ka hoʻomaikaʻi ʻana i ka hana o ka pale electromagnetic a me ka hoʻopili ʻana i nā mea e pili ana i ka ʻike o ka mea hoʻopili, nā waiwai o ka mea hoʻopili a me ka hoʻohālikelike maikaʻi ʻana o ka substrate absorbing.ʻAʻole wale ʻo Graphene kahi hoʻolālā kino kūʻokoʻa a me nā waiwai mechanical a me electromagnetic maikaʻi, akā loaʻa pū kekahi mau waiwai absorption microwave maikaʻi.Ke hoʻohui pū ʻia me nā nanoparticles magnetic, hiki ke loaʻa i kahi mea hoʻoheheʻe hou, nona ka poho magnetic a me ka nalowale uila.Loaʻa iā ia kahi manaʻo hoʻohana maikaʻi i ke kahua o ka pale electromagnetic a me ka absorption microwave.
