He aha ka photocatalysis māmā?
ʻO ka photocatalysis māmā ʻike ʻia e pili ana i ka photocatalytic oxidation a me ka hoʻohaʻahaʻa ʻana o ka photocatalyst ma lalo o nā kūlana mālamalama ʻike ʻia.
He aha ke kumu o ka photocatalysis māmā?
Hoʻokumu ʻia ka loina catalytic māmā ʻike ʻia ma luna o ka ikehu māmā irradiation māmā catalyst, catalyst valence band o ka māmā ʻāina mokuʻāina electron transition i ka conduction band, hana i ka malamalama hānau puka a me ka uila uila, puka māmā me nā mole wai e hoʻohua ai i nā radical free hydroxyl, electrons and oxygen mole reaction produces super oxygen anion, a me nā lua, hydroxyl radicals a me nā mea kanu o ka oxygen superactive. nā mea haumia ʻē aʻe i loko o ka wai a me carbon dioxide a me nā molekole liʻiliʻi ʻē aʻe. ʻO kahi liʻiliʻi o N, S a me P i loko o ka mea organik e hoʻohua i ka nitrate, sulfate, phosphate a pēlā aku ma hope o ka degradation, i mea e pāʻani ai i kahi detoxification, deodorization a me ka hopena sterilization. Hāʻawi ka ʻenehana uhi photocatalytic māmā i kahi ʻōmaʻomaʻo hou no ka mālama ʻana i ka ea o loko a me waho.
No ke aha e hoʻohana ai i ka photocatalysis māmā?
E like me ka wehewehe ʻana i ka pae aupuni GB / T 17683.1-1999, ʻo ka kukui ultraviolet i ka lā he 7% wale nō, ʻo ke kukui ʻike ʻia he 71%, a ʻo ka helu infrared no 22%. ʻOiai ʻoi aku ka nui o ka ikehu o ka photon ultraviolet ma mua o ke kukui ʻike ʻia a i ʻole ke kukui infrared, ʻo ke kukui ʻike ʻia a me ke kukui infrared "lanakila" ma ka helu. Kuʻuna photocatalytic oxidation ʻenehana aia wale nō ma lalo o ka hana o ka ultraviolet light oxidation degradation o nā mea haumia. A ʻo jiangyin lā mokuʻāina quantum coating ʻenehana co., LTD. ʻO ka huahana o nā huahana ʻenehana catalytic oxidation ʻike a me ka pae nui TiO2, hiki i kāna hana ke hana ʻaʻole wale i ka ʻike ʻia o ka photocatalytic oxidation degradation, akā hiki nō hoʻi i ka catalytic oxidation degradation ma lalo o ka ultraviolet a me ka infrared light reaction.
