He aha ka photocatalysis mālamalama ʻike ʻia?
ʻO ka photocatalysis mālamalama ʻike ʻia e pili ana i ka oxidation photocatalytic a me ka degradation o ka photocatalyst ma lalo o nā kūlana mālamalama ʻike ʻia.
He aha ke kumumanaʻo o ka photocatalysis mālamalama ʻike ʻia?
Hoʻokumu ʻia ke kumumanaʻo catalytic māmā ʻike ʻia ma ka hoʻomālamalama ʻana o ka māmā ʻike ʻia, ka hoʻololi ʻana o ke kaula valence o ka māmā i ka electron state state i ka band conduction, e hana i ka lua hānau māmā a me ka uila māmā, ka lua māmā me nā mole wai e hana i nā radical free hydroxyl, nā electrons a me ka oxygen molecule e hana i nā anion oxygen super, a me nā lua, nā radical hydroxyl a me ka hana ʻana o nā anion superoxide. Hiki i nā ʻano oxygen reactive ke hoʻohaʻahaʻa i nā mole ʻala, nā mea ola, nā bacteria a me nā mea haumia ʻē aʻe i loko o ka wai a me ke kalapona dioxide a me nā mole liʻiliʻi ʻē aʻe. ʻO kahi liʻiliʻi o N, S a me P i loko o nā mea ola e hana i ka nitrate, sulfate, phosphate a pēlā aku ma hope o ka hoʻohaʻahaʻa ʻana, i mea e hoʻopau ai i ka ʻona, deodorization a me ka sterilization. Hāʻawi ka ʻenehana uhi photocatalytic māmā ʻike ʻia i kahi hopena ʻōmaʻomaʻo hou no ka mālama ʻana i ke kaiapuni ea o loko a me waho.
No ke aha e hoʻohana ai i ka photocatalysis mālamalama ʻike ʻia?
Wahi a ka wehewehe ʻana ma ke kūlana aupuni GB/T 17683.1-1999, ʻo ka mālamalama ultraviolet i ka lā wale nō ka helu no 7%, ʻo ka mālamalama ʻike ʻia ka helu no 71%, a ʻo ka infrared ka helu no 22%. ʻOiai ʻoi aku ka nui o ka ikehu o kahi photon ultraviolet ma mua o ka mālamalama ʻike ʻia a i ʻole ka mālamalama infrared, ʻo ka mālamalama ʻike ʻia a me ka mālamalama infrared "lanakila" ma ka helu. ʻO ka ʻenehana oxidation photocatalytic kuʻuna wale nō ma lalo o ka hana o ka ultraviolet light oxidation degradation o nā mea haumia organik. A ʻo jiangyin day state quantum coating technology co., LTD. ʻO ka huahana o ka ʻenehana oxidation catalytic māmā ʻike ʻia a me ka pae quantum TiO2, hiki i kāna hana ke hana ʻaʻole wale ma ka mālamalama ʻike ʻia photocatalytic oxidation degradation, akā hiki nō hoʻi ke catalytic oxidation degradation ma lalo o ka ultraviolet a me ka infrared light reaction, he pane spectrum piha hou ia o ka ʻenehana photocatalytic, i hoʻomaikaʻi nui i ka pono.
