Ua ʻike ʻia nā mea hoʻoheheʻe kukui UltraViolet i nā mea hoʻomohala plastik, no kekahi manawa, ma ke ʻano he mea hoʻohui pono e pale i nā plastics mai nā hopena hoʻohaʻahaʻa lōʻihi o ka lā.Ua ʻike ʻia nā mea hoʻoheheʻe infrared i kahi pūʻulu liʻiliʻi o nā mea hoʻomohala plastik.Eia naʻe, i ka loaʻa ʻana o ka laser i hoʻonui ʻia ka hoʻohana ʻana i kēia pūʻulu ʻike ʻole o nā mea hoʻohui e hoʻonui nei i ka hoʻohana.

I ka lilo ʻana o nā lasers i ʻoi aku ka ikaika, i ka hopena o nā kanaono a me nā makahiki he kanahiku, ua ʻike ʻia e pono ke pale ʻia nā mea hoʻohana laser mai ka hopena makapō o ka radiation infrared.Ma muli o ka mana, a me ka pili o ka laser i ka maka, hiki i ka makapō no ka manawa a mau loa paha.Ma kahi o ka manawa like, me ka hoʻolaha ʻana o ka polycarbonate, ua aʻo ka poʻe molder i ka hoʻohana ʻana i nā infrared absorbers i nā papa no nā pale pale maka o ka welder.Hāʻawi kēia hana hou i ka ikaika hopena kiʻekiʻe, ka pale ʻana mai ka radiation infrared a me ke kumu kūʻai haʻahaʻa ma mua o nā pā aniani i hoʻohana ʻia.

Inā makemake kekahi e ālai i ka radiation infrared a pau, a ʻaʻole hopohopo e pili ana i ka ʻike ma o ka hāmeʻa, hiki ke hoʻohana i ke kalapona ʻeleʻele.Eia nō naʻe, koi ka nui o nā noi i ka hoʻouna ʻana i nā kukui ʻike a me ka pale ʻana i nā lōʻihi nalu infrared.Aia kekahi o kēia mau noi:

Nā Makana Koa - Hoʻohana ʻia nā laser ikaika e ka pūʻali koa no ka ʻimi ʻana a me ka ʻike ʻana i nā mea kaua.Ua hōʻike ʻia i ka wā o ke kaua ʻo Iran - Iraq o nā makahiki kanawalu, ua hoʻohana ka poʻe Iraqis i ka mea ʻimi laser ikaika ma kā lākou mau pahu i mea kaua e makapō i ka ʻenemi.Ua lohe ʻia e hoʻomohala ana kekahi ʻenemi i kahi laser ikaika e hoʻohana ʻia i mea kaua, i manaʻo ʻia e makapō i nā pūʻali ʻenemi.Hoʻopuka ka laser Neodynium/YAG i ke kukui ma 1064 nanometers (nm), a hoʻohana ʻia no ka ʻimi ʻana i ka laulā.No laila, ʻaʻahu nā koa i kēia lā i nā maka aniani me kahi lens polycarbonate i hoʻohui ʻia i hoʻokahi a ʻoi aku paha nā Infrared Absorbers, e hoʻomoʻa ikaika i ka 1064 nm, e pale iā lākou mai ka ʻike ʻana i ka laser Nd/YAG.

Lapaʻau Lapaʻau - ʻOiaʻiʻo, he mea nui i nā koa ke loaʻa i nā kukui ʻike maikaʻi ʻia i nā goggles, kahi e pale ai i ka Infrared Radiation.ʻOi aku ka mea nui i nā limahana lapaʻau e hoʻohana ana i nā lasers i ʻike maikaʻi ʻia ke kukui ʻike ʻia, ʻoiai e pale ʻia mai ka ʻike ʻana i nā lasers a lākou e hoʻohana nei.Pono e hoʻopili ʻia ka infrared absorber i koho ʻia i mea e komo ai ka mālamalama i ka lōʻihi o ka hoʻokuʻu ʻana o ka laser i hoʻohana ʻia.Ke piʻi aʻe ka hoʻohana ʻana i nā lasers i ka lāʻau lapaʻau, e hoʻonui pū ka pono no ka pale ʻana mai nā hopena ʻino o ka radiation infrared.

Welder's Face Plates and Goggles - E like me ka mea i ʻōlelo ʻia ma luna nei, ʻo ia kekahi o nā noi kahiko loa o Infrared Absorbers.I ka wā ma mua, ua hōʻike ʻia ka mānoanoa a me ka ikaika o ka hopena o ka pā alo e kahi kūlana ʻoihana.Ua koho mua ʻia kēia kikoʻī no ka mea e ʻā ana nā infrared absorbers i hoʻohana ʻia i kēlā manawa inā e hana ʻia ma kahi wela kiʻekiʻe.Me ka hiki ʻana mai o nā Infrared Absorbers me ke kūpaʻa wela nui, ua hoʻololi ʻia ka kikoʻī i ka makahiki i hala e ʻae i nā maka maka o kekahi mānoanoa.

Ke alo aku nei nā limahana hana uila i nā pale - Hiki ke ʻike ʻia nā limahana Utility Utility i ka radiation infrared koʻikoʻi inā loaʻa ka arcing o nā kaula uila.Hiki ke makapō kēia radiation, a i kekahi manawa ua make.Ua kōkua nā pale maka i hoʻokomo ʻia i nā mea hoʻoheheʻe infrared i ka hōʻemi ʻana i nā hopena pōʻino o kekahi o kēia mau ulia.I ka wā ma mua, pono e hana ʻia kēia mau pale maka me ka cellulose acetate propionate, no ka mea, e puhi ʻia ka infrared absorber inā hoʻohana ʻia ka polycarbonate.I kēia mau lā, ma muli o ka hiki ʻana mai o nā mea hoʻoheheʻe infrared thermally stable, ua hoʻolauna ʻia nā pale alo polycarbonate, e hāʻawi ana i kēia poʻe limahana i ka pale o ka hopena kiʻekiʻe.

ʻO nā aniani ski kiʻekiʻe - ʻike ʻia ka lā mai ka hau a me ka hau hiki ke loaʻa ka hopena makapō i ka poʻe ski.Ma waho aʻe o nā mea hoʻonani, e hoʻonani i nā maka aniani, a me nā mea hoʻomaʻamaʻa kukui ultraviolet e pale ai mai ka radiation UVA a me UVB, ke hoʻohui nei kekahi mau mea hana i nā mea hoʻoheheʻe infrared e pale aku i nā hopena pōʻino o ka radiation infrared.

Nui nā noi hoihoi ʻē aʻe e hoʻohana ana i nā waiwai kūikawā o nā infrared absorbers.Hoʻopili kēia i nā papa paʻi lithographic laser ablated, ka hoʻoheheʻe ʻia ʻana o ka kiʻiʻoniʻoni plastik, nā pani puka aniani, a me nā inika palekana.

ʻO nā hui nui ʻekolu o nā kemika i hoʻohana ʻia ma ke ʻano he infrared absorbers ʻo ia nā cyanines, nā paʻakai aminium a me nā dithiolenes metala.ʻO nā cyanines he mau molekole liʻiliʻi a no laila ʻaʻohe paʻa wela e hoʻohana ʻia i ka polycarbonate i hoʻoheheʻe ʻia.ʻO nā paʻakai aminium he mau molekala nui a ʻoi aku ka paʻa o ka wela ma mua o nā cyanines.Ua hoʻonui nā mea hou i loko o kēia kemika i ka wela hoʻoheheʻe kiʻekiʻe loa o kēia mau mea hoʻoheheʻe mai 480oF a i 520oF.Ma muli o ke kemika o nā paʻakai aminium, hiki i kēia mau mea ke loaʻa nā spectra absorption infrared, mai ka laulā a hiki i ka haiki.ʻO nā dithiolenes metala ka mea paʻa loa i ka wela, akā loaʻa ka hemahema o ka pipiʻi loa.Loaʻa i kekahi nā spectra absorption, he haiki loa.Inā ʻaʻole synthesized pono, hiki i nā dithiolenes metala ke hāʻawi i kahi ʻala sulfur ʻino i ka wā e hana ai.

ʻO nā waiwai o nā infrared absorbers, ʻo ia ka mea nui loa i nā molders polycarbonate, ʻo ia:

Thermal Stability - pono e mālama nui ʻia i ka hoʻokumu ʻana a me ka hana ʻana i ka polycarbonate i loaʻa nā aminium paʻakai infrared absorbers.Pono e helu ʻia ka nui o ka mea hoʻoheheʻe no ka pale ʻana i ka nui o ka radiation i makemake ʻia me ka nānā ʻana i ka mānoanoa o ka lens.Pono e hoʻoholo a nānā pono i ka wela o ka hoʻolaha ʻana a me ka manawa.Inā noho ka mea hoʻoheheʻe infrared i loko o ka mīkini hoʻoheheʻe ʻia i ka wā o ka "hoʻomaha kofe lōʻihi", e ʻā ka mea hoʻopau a hōʻole ʻia nā ʻāpana mua i hoʻoheheʻe ʻia ma hope o ka haki ʻana.Ua ʻae kekahi mau mea hoʻoheheʻe infrared aminium paʻakai hou e hoʻonui ʻia ka mahana hoʻoheheʻe palekana mai 480oF a i 520oF, a laila e hōʻemi ana i ka helu o nā ʻāpana i hōʻole ʻia ma muli o ke ahi.

Absorptivity - ʻo ia ke ana o ka mana ālai infrared o ka mea absorber no kēlā me kēia ʻāpana o ke kaumaha, ma kahi lōʻihi nalu.ʻO ke kiʻekiʻe o ka absorptivity, ʻoi aku ka nui o ka mana pale.He mea nui i ka mea hoolako o infrared absorber i maikai batch-to-batch kūlike o ka absorptivity.Inā ʻaʻole, e hoʻoponopono hou ʻoe me kēlā me kēia pūʻulu o ka absorber.

ʻIke ʻia ke kukui (VLT) - Ma ka hapa nui o nā noi makemake ʻoe e hōʻemi i ka hoʻouna ʻana o ke kukui infrared, mai 800 nm a 2000nm, a e hoʻonui i ka lawe kukui ʻike ʻia mai 450nm a 800nm.ʻOi aku ka maʻalahi o ka maka kanaka i ka mālamalama ma kahi o 490nm a 560nm.ʻO ka mea pōʻino, hoʻopaʻa ʻia nā mea hoʻoheheʻe infrared i loaʻa i kekahi kukui ʻike ʻia a me nā kukui infrared, a hoʻohui i kekahi kala, ʻōmaʻomaʻo maʻamau i ka ʻāpana i hoʻoheheʻe ʻia.

Haze - E pili ana i ka hoʻouna māmā ʻike ʻia, he waiwai koʻikoʻi ka haze i nā maka maka no ka mea hiki ke hōʻemi nui i ka ʻike.Hiki ke hana ʻia ka hau e nā haumia i loko o ka IR Dye, ʻaʻole i hoʻoheheʻe ʻia i ka polycarbonate.Hana ʻia nā aminium IR Dyes hou ma ke ʻano e hoʻopau loa ʻia kēia mau mea haumia, a laila e hoʻopau ʻia ka haze mai kēia kumu, a me ka hoʻomaikaʻi ʻana i ke kūpaʻa wela.

ʻO nā huahana i hoʻomaikaʻi ʻia a me ka maikaʻi i hoʻomaikaʻi ʻia - ʻO ke koho kūpono o nā Infrared Absorbers, hiki i ka mea hana plastics ke hāʻawi aku i nā huahana me nā waiwai hana i hoʻomaikaʻi ʻia a me ka pae kiʻekiʻe o ka maikaʻi.

No ka mea, ʻoi aku ka nui o ke kumukūʻai o nā mea hoʻoheheʻe infrared ma mua o nā mea hoʻohui plastik ʻē aʻe ($/gram ma kahi o $/lb), he mea nui ia e mālama nui ka mea hoʻopuka i ka hana pololei e pale aku ai i ka pau ʻole, a loaʻa ka hana e pono ai.He mea nui ia e hoʻomohala pono ka mea hana i nā kūlana hana pono e pale aku ai i ka hana ʻana i nā huahana off-spec.He hana paʻakikī kēia, akā hiki ke hopena i nā huahana kiʻekiʻe i hoʻohui ʻia.
