E hana ana ka ikehu kani ultrasonic ma ka mea waena, e hoʻonāwaliwali i nā ʻāpana i ka wikiwiki kiʻekiʻe a hana i nā loli mechanical e like me ka wikiwiki, ka wikiwiki, ke kani kani, a me ka ikaika o ke kani, a laila e hoʻoulu ai i nā hopena mechanical. ʻO ke kani kani ke ʻano o ka hoʻolaha ʻana o ka ikehu mechanical, e pili ana i ke kaʻina hawewe a e hoʻopuka i kahi hopena laina o ka vibration. Ke hoʻolaha ʻia ka hawewe kani ultrasonic ma ke kikowaena, ʻoiai he liʻiliʻi ka amplitude o ka neʻe ʻana o ka particle, ʻoi aku ka nui o ka wikiwiki o ka mea i hana ʻia e ka hawewe kani ultrasonic.
Inā hoʻolaha ka hawewe kani ultrasonic 20kHz, 1W/cm2 i ka wai, ʻo ka amplitude kani kani i hana ʻia e ia he 173kPa, ʻo ia hoʻi, pono e hoʻololi ke kani kani amplitude i 20,000 mau manawa ma waena o ka maikaʻi a me ka maikaʻi ʻole 173kPa i kēlā me kēia kekona, a ʻo ka piʻi ʻana o ka nui a hiki i ka 1440km/s1500 mau manawa o ka gravity. ʻO ka hoʻololi wikiwiki ʻana i ka neʻe mechanical ka hopena haʻalulu mechanical o ka mana ultrasound.
Inā ʻaʻole ʻo ke ʻano o ke kani ultrasonic he ʻano ʻano like ʻole (e like me ka ʻiʻo biological, ke kino kanaka, a me nā mea ʻē aʻe), ʻo ka impedance acoustic o kēlā me kēia papa o ka media e hoʻohālikelike i nā hawewe kani i ʻike ʻia a hana i kahi nalu kū. ʻO nā antinodes a me nā nodes o ka nalu kū ke kumu o ke kaomi a me ka ʻuʻuku A hoʻololi ka wikiwiki. No ka mea ʻokoʻa ka nui o nā ʻāpana media like ʻole (e like me nā biomolecules), ʻokoʻa ka wikiwiki o ka vibration i hoʻololi ʻia e ka hoʻololi kaomi, a ʻo ka hoʻololi ʻana i ke kaomi ma muli o ka neʻe pili ma waena o nā ʻāpana media kekahi kumu o ka hopena mechanical ultrasonic. ʻO nā hopena mechanical e hoʻohana ana i ka ultrasound e pono e hanaʻia (perforation,ʻokiʻoki, hoʻopili, hoʻoikaika i kaʻili, hoʻomaʻemaʻe, hoʻomaʻemaʻe, polishing, a me ka weheʻana i nā kiʻiʻoniʻoni a me ka lepo, a me nā mea'ē aʻe), a hoʻohanaʻia hoʻi e hoʻonui i ka dispersion, homogenization, emulsification, and crushing , Sterilization a me nā hana'ē aʻe.
Ua hoʻohana nui ʻia ka hopena mechanical o ka ultrasound i ka hana ʻana, a penei nā hiʻohiʻona.
ʻO ka hoʻoulu ʻana i ka mīkini
Hiki ke hoʻoulu ʻia ka haʻalulu a me ke kahe ʻana i ke kinoea a me ka wai. Hiki ke hoʻonāwaliwali ka jet ikaika a me ka micro-rush kūloko e ka cavitation bubble vibration ma ka ʻili paʻa ke hoʻonāwaliwali i ka ʻili o ka ʻili a me ka friction o ka wai, a hoʻopau i ka papa i hoʻopili ʻia o ka pilina paʻa-wai, no laila ʻaʻole hiki ke hiki i ka haʻahaʻa haʻahaʻa mechanical agitation. hopena. ʻO kēia hopena ke kumu kino no ka hoʻohana ʻana i nā lāʻau lapaʻau ma o ka ʻili kanaka, nā huahana nani i ka ʻili kanaka, ultrasonic degassing, meaʻai a me ka hoʻomaʻemaʻe ʻana.
Interdiffusion
Hoʻohana ʻia ke kaomi a me ke kiʻekiʻe wela o ka haʻalulu kani ultrasonic a me ka cavitation e hāpai i ke komo ʻana o nā molekole ma waena o ʻelua mau wai, ʻelua paʻa, a i ʻole nā wai-paʻa a me nā wai-kino e hana i nā waiwai waiwai hou. Ultrasonic welding o nā metala a i ʻole plastics, ultrasonic emulsification, hoʻomaʻemaʻe, atomization hiki ke helu ʻia e like me nā hopena.
Homogenize
Ma hope o ka pani ʻia ʻana o nā puʻupuʻu cavitation, hiki i ka nalu haʻalulu kūloko ke wāwahi i nā ʻāpana i loko o ka wai e hoʻomaikaʻi ai; e hana i ka lole aniani; e hoʻopuehu i nā kulu waiu nui ʻole i loko o nā ʻāpana liʻiliʻi liʻiliʻi (e like me nā lāʻau lapaʻau hoʻohālikelike, nā lāʻau lapaʻau maʻi kanesa, etc.); Hiki iā ia ke komo i ka thrombolysis a me nā hopena ʻē aʻe.
Hoʻohui
Hiki i ka haʻalulu kani ultrasonic ke hoʻoneʻe i nā ʻāpana i hoʻokuʻu ʻia i loko o ke kinoea a me ka wai i nā wikiwiki like ʻole, e hoʻonui ana i ka manawa o ka hui ʻana; a i ʻole ka hoʻohana ʻana i nā nalu kū e hana ai i nā antinodes, no laila e hana ʻia ke kaʻina hoʻohui. Hāʻule ka ʻohi lepo i loko o kēia ʻāpana.
Hana ʻoki mīkini
Ma muli o ka wikiwiki nui o ka ultrasonic vibration a me ka hopena o ka cavitation a me ka acoustic corrosion, hiki ke hana i ka hana kūikawā a me ka pololei o nā mea paʻakikī a me nā mea palupalu (gems, ceramics, glass, magnetic steel, etc.)

Hiki i ka hoʻohana ʻana i nā puʻupuʻu ultrasound kiʻekiʻe ke ʻoki i nā pōhaku ʻāʻī a me nā gallstones i loko o ke kino me ka ʻole e hōʻino i nā ʻiʻo palupalu.
