nā ʻano kemika

ʻO ka mea hoʻoheheʻe ultraviolet kahi ʻano hoʻopaʻa kukui, hiki ke omo i ka lā a me ke kumu kukui fluorescent i ka ʻāpana ultraviolet, akā ʻaʻole ia e loli.
Ma muli o ka loaʻa ʻana o ka nui o ka mālamalama ultraviolet i nā mea kala i loko o nā kukuna o ka lā, ʻo kona nalu lōʻihi ma kahi o 290-460 nanometers, a ma o ka hopena kemika Redox, e palaho a mae nā mole kala.
Aia nā ala kino a me nā kemika e pale aku ai i ka hōʻino ʻana o ke kala mai ka mālamalama UV ʻino.
Eia kahi hoʻolauna pōkole i ke ʻano kemika, ʻo ia hoʻi, ka hoʻohana ʻana i nā mea hoʻoheheʻe UV e pale i ka mea i ka pale kūpono, a i ʻole e hoʻonāwaliwali i kona luku ʻia ʻana o ke kala.
Pono nā mea hoʻoheheʻe UV i nā kūlana aʻe
(1) hiki ke omo ikaika i ka mālamalama ultraviolet (ʻoi aku ka nalu o 290-400nm); (2) Paʻa maikaʻi ka wela, ʻoiai i ka hana ʻana ʻaʻole e loli ma muli o ka wela, liʻiliʻi ka volatility wela; Paʻa kemika maikaʻi, ʻaʻohe hopena maikaʻi ʻole me nā ʻāpana mea i loko o ka huahana; (4) Miscibility maikaʻi, hiki ke hoʻopuehu like ʻia i loko o ka mea, ʻaʻohe hau, ʻaʻohe exudation; (5) Maikaʻi ke kūpaʻa photochemical o ka mea absorbent ponoʻī, ʻaʻole e pala, ʻaʻole e loli ke kala; ⑥ ʻAʻohe kala, ʻaʻohe ʻawaʻawa, ʻaʻohe ʻala; ⑦ kū'ē i ka holoi hoʻoluʻu; ⑧ Makepono a maʻalahi ke kiʻi; 9. Insoluble a i ʻole insoluble i ka wai.
Hiki ke hoʻokaʻawale ʻia nā mea hoʻomohu UV i loko o nā hui ma lalo nei e like me ko lākou ʻano kemika: salicylate esters, phenylketones, benzotriazoles, acrylonitrile i pani ʻia, triazine a me nā amine i ālai ʻia.

Hoʻolauna huahana a me nā hiʻohiʻona

ʻO ka mea hoʻoheheʻe ultraviolet ka mea hoʻopaʻa kukui hoʻokahi i hoʻohana nui ʻia, e like me kona ʻano hiki ke hoʻokaʻawale ʻia i nā esters salicylate, benzophenone, benzotriazole, acrylonitrile i pani ʻia, triazines, etc., ʻo ka noi ʻoihana o ka benzophenone a me benzotriazole ka nui. ʻO ka mea hoʻopau wela he mea paʻakikī metala nui, e like me ka paʻakikī nickel divalent, pinepine a me ka ultraviolet absorbent a me ka hopena synergistic, ʻo ka ultraviolet absorbent kahi ʻano hoʻopaʻa kukui, hiki ke omo i ka lā a me ke kumu kukui fluorescent i ka ʻāpana ultraviolet, a ʻaʻole ia e loli.
Ma muli o ka loaʻa ʻana o ka nui o ka mālamalama ultraviolet i nā mea kala i loko o nā kukuna o ka lā, ʻo kona nalu lōʻihi ma kahi o 290-460 nanometers, a ma o ka hopena kemika Redox, e palaho a mae nā mole kala.
Aia nā ala kino a me nā kemika e pale aku ai i ka hōʻino ʻana o ke kala mai ka mālamalama UV ʻino.
Eia kahi hoʻolauna pōkole i ke ʻano kemika, ʻo ia hoʻi, ka hoʻohana ʻana i nā mea hoʻoheheʻe UV e pale i ka mea i ka pale kūpono, a i ʻole e hoʻonāwaliwali i kona luku ʻia ʻana o ke kala

hoʻohana

Hiki iā ia ke omo pono i ka mālamalama ultraviolet me ka nalu o 270-380 nm, hoʻohana nui ʻia no ka polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin a me cellulose resin, a pēlā aku. He kūpono ia no nā mea photosensitive e like me ke kiʻiʻoniʻoni kala, ke kiʻiʻoniʻoni kala, ka pepa kala a me ka polymer, a pēlā aku. Kūpono loa no nā huahana aniani a me nā huahana māmā ʻole; No ka omo ikaika, ka mea hoʻomoʻa ultraviolet hana kiʻekiʻe

pūʻolo a me ka halihali

B. Hiki ke hoʻohana ʻia kēia huahana, 25KG, BAERRLS.
C. E mālama pono i kahi i hoʻopaʻa ʻia ma kahi anu, maloʻo a me ka ea i loko. Pono e hoʻopaʻa pono ʻia nā ipu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa pono ʻia kēia huahana i ka wā o ka lawe ʻana e pale aku i ka makū, ka alkali ikaika a me ka waikawa, ka ua a me nā mea haumia ʻē aʻe mai ka hui pū ʻana.
