ʻO ka pāhawewe infrared (IR) kekahi ʻano o ka pāhawewe electromagnetic i ʻike ʻole ʻia e ka maka kanaka akā hiki ke ʻike ʻia he wela.Loaʻa iā ia ka laulā o nā noi e like me nā mana mamao, nā lako kiʻi thermal, a me ka kuke ʻana.Eia nō naʻe, aia kekahi mau manawa e pono ai ke kāohi a hōʻemi paha i nā hopena o ka radiation infrared, e like me kekahi mau hoʻokolohua ʻepekema, nā kaʻina hana ʻoihana, a i ʻole no nā kumu olakino a palekana.I kēia hihia, hiki ke hoʻohana ʻia nā mea kikoʻī e hoʻemi a paʻa loa i ka radiation infrared.

ʻO kekahi mea i hoʻohana mau ʻia no ka pale ʻana i ka radiation IRNā ʻāpana pale IR.Hoʻokumu pinepine ʻia kēia mau ʻāpana me ka hui pū ʻana o nā mea e like me nā oxide metala a ua hoʻolālā pono ʻia e hoʻomoʻa a hōʻike i ka radiation infrared.ʻO nā mea hoʻoheheʻe metala maʻamau i loaʻa i loko o nā ʻāpana pale infrared me ka zinc oxide, titanium oxide, a me ka hao hao.Hoʻohui pinepine ʻia kēia mau ʻāpana me ka polymer a i ʻole ka resin base e hana i nā kiʻiʻoniʻoni a i ʻole nā ​​​​pale i hiki ke hoʻopili ʻia i nā ʻano like ʻole.

ʻO ka maikaʻi o nā ʻāpana pale infrared e pili ana i nā kumu he nui, me ka nui a me ke ʻano o nā ʻāpana, a me kā lākou ʻike ʻana i ke kiʻiʻoniʻoni a i ʻole ka uhi.ʻO ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o nā ʻāpana liʻiliʻi a me nā koʻikoʻi kiʻekiʻe i nā waiwai pale IR.Eia kekahi, hiki i ke koho ʻana i ka metala oxide ke hoʻopili i ka pono o ka mea pale infrared.No ka laʻana, ʻike ʻia nā ʻāpana zinc oxide i ka pale pono ʻana i kekahi mau nalu nalu o ka radiation infrared, ʻoiai ʻoi aku ka maikaʻi o ka titanium oxide ma nā hawewe ʻē aʻe.

Ma waho aʻe o nā ʻāpana pale infrared, aia nā mea ʻē aʻe i hiki ke hoʻohana ʻia e pale a hoʻemi paha i ka pāhawewe infrared.ʻO kahi koho kaulana ʻo ia ka hoʻohana ʻana i nā mea me ka noʻonoʻo kiʻekiʻe, e like me nā metala e like me ke alumini a i ʻole ke kālā.Loaʻa i kēia mau metala ke kiʻekiʻe o ka nānā ʻana i ka ʻili, ʻo ia ka mea hiki iā lākou ke hōʻike i ka nui o ka radiation infrared i kona kumu.Hoʻemi maikaʻi kēia i ka nui o ka radiation infrared e hele ana i ka mea.

ʻO kahi ala ʻē aʻe e ālai ai i ka radiation infrared ʻo ia ka hoʻohana ʻana i nā mea me nā waiwai e hoʻomoe loa.ʻO kekahi mau pūhui organik, e like me ka polyethylene a me kekahi mau ʻano aniani, loaʻa nā coefficient absorption kiʻekiʻe no ka pāhawewe infrared.ʻO ia ke ʻano o ka hoʻomoʻa ʻana i ka hapa nui o ka radiation infrared e pili ana me lākou, e pale ana i ka hele ʻana.

Ma waho aʻe o ka mea kikoʻī, pili ka mānoanoa a me ka nui o ka mea i kona hiki ke pale i ka radiation infrared.ʻOi aku ka maikaʻi o nā mea ʻoi aku ka mānoanoa a me nā mea ʻoi aku ka nui o ka infrared blocking ma muli o ka hoʻonui ʻia o ka infrared absorbing or reflecting particles i kēia manawa.

I ka hōʻuluʻulu ʻana, aia nā ʻano mea like ʻole e hiki ke hoʻohana ʻia no ka pale ʻana a i ʻole ka hoʻemi ʻana i ka radiation infrared.Nā ʻāpana ʻāpana ʻāʻī infrared, e like me nā mea i hana ʻia me nā oxides metala, ua hoʻohana nui ʻia ma muli o ko lākou mau waiwai kikoʻī e hiki ai iā lākou ke komo a hōʻike i ka radiation infrared.Eia nō naʻe, hiki ke hoʻohana ʻia nā mea ʻē aʻe, e like me nā metala me ka hoʻohālikelike kiʻekiʻe a i ʻole nā ​​pūhui organik me nā coefficient absorption kiʻekiʻe.ʻO nā mea e like me ka nui o ka particle, ka ʻike a me ke ʻano o ka metala oxide i hoʻohana ʻia he kuleana koʻikoʻi i ka pono o nā mea pale IR.Hoʻokomo pū ka mānoanoa a me ka mānoanoa i ka hiki o kahi mea ke ālai i ka pāhawewe infrared.Ma ke koho ʻana i nā mea kūpono a me ka noʻonoʻo ʻana i kēia mau kumu, hiki ke hoʻokō ʻia ka pale ʻana i ka IR kūpono i nā ʻano noi.
