A farkon aikace-aikace na duban dan tayi a biochemistry ya kamata a farfasa bangon tantanin halitta da duban dan tayi don saki abinda ke ciki.Binciken da ya biyo baya ya nuna cewa ƙananan ƙarfin duban dan tayi na iya inganta tsarin halayen kwayoyin halitta.Alal misali, ultrasonic sakawa a iska mai guba tushe na ruwa mai gina jiki zai iya ƙara yawan girma na algal Kwayoyin, don haka kara adadin gina jiki samar da wadannan Kwayoyin sau uku.

Idan aka kwatanta da yawan makamashi na cavitation kumfa rushewa, da makamashi yawa na ultrasonic sauti filin da aka kara girma da trillions na sau, haifar da wata babbar taro na makamashi;Sonochemical mamaki da sonoluminescence lalacewa ta hanyar high zafin jiki da kuma matsa lamba samar da cavitation kumfa ne na musamman siffofin makamashi da kuma kayan musayar a sonochemistry.Saboda haka, duban dan tayi taka wani ƙara muhimmiyar rawa a sinadaran hakar, biodiesel samar, Organic kira, microbial jiyya, ƙasƙantar da guba Organic pollutants, sinadaran dauki gudun da yawan amfanin ƙasa, catalytic yadda ya dace da kara kuzari, biodegradation magani, ultrasonic sikelin rigakafin da kau, nazarin halittu cell crushing. , watsawa da agglomeration, da kuma sonochemical dauki.

1. ultrasonic inganta sinadaran dauki.

Duban dan tayi inganta sinadaran dauki.Babban ƙarfin tuƙi shine cavitation ultrasonic.Rushewar cavitating kumfa core yana samar da babban zafin jiki na gida, babban matsin lamba da tasiri mai ƙarfi da micro jet, wanda ke ba da sabon yanayi na musamman na zahiri da sinadarai don halayen sinadarai waɗanda ke da wahala ko ba za a iya cimma su a ƙarƙashin yanayin al'ada ba.

2. Ultrasonic catalytic dauki.

A matsayin sabon filin bincike, ultrasonic catalytic dauki ya janyo hankali fiye da sha'awa.Babban tasirin duban dan tayi akan halayen catalytic sune:

(1) Babban zafin jiki da matsanancin matsin lamba suna dacewa da fashewar reactants a cikin radicals na kyauta da carbon divalent, suna samar da nau'ikan halayen aiki;

(2) Shock kalaman da micro jet da desorption da tsaftacewa effects a kan m surface (kamar kara kuzari), wanda zai iya cire surface dauki kayayyakin ko matsakaici da kara kuzari surface passivation Layer;

(3) Girgiza igiyar ruwa na iya lalata tsarin mai amsawa

(4) Watsewar tsarin amsawa;

(5) Ultrasonic cavitation erodes karfe surface, da kuma girgiza kalaman take kaiwa zuwa nakasawa na karfe lattice da samuwar na ciki iri yankin, wanda inganta sinadaran dauki aiki na karfe;

6) Ƙaddamar da sauran ƙarfi don shiga cikin m don samar da abin da ake kira haɗawa;

(7) Don inganta watsawar mai kara kuzari, ana amfani da ultrasonic sau da yawa a cikin shirye-shiryen mai kara kuzari.Ultrasonic sakawa a iska mai guba na iya kara yawan farfajiya na mai kara kuzari, sa kayan aiki masu aiki su watse sosai kuma suna haɓaka aikin catalytic.

3. Ultrasonic polymer chemistry

A aikace na ultrasonic tabbatacce polymer sunadarai ya jawo hankalin m.Ultrasonic jiyya na iya wulakanta macromolecules, musamman high kwayoyin nauyi polymers.Cellulose, gelatin, roba da furotin za a iya ƙasƙanta da ultrasonic jiyya.A halin yanzu, an yi imani da cewa tsarin lalacewa na ultrasonic shine saboda tasirin karfi da matsa lamba lokacin da kumfa cavitation ya fashe, kuma ɗayan ɓangaren lalacewa na iya zama saboda tasirin zafi.A karkashin wasu yanayi, ikon duban dan tayi kuma zai iya fara polymerization.Strong duban dan tayi sakawa a iska mai guba zai iya fara da copolymerization na polyvinyl barasa da acrylonitrile shirya block copolymers, da kuma copolymerization na polyvinyl acetate da polyethylene oxide don samar da dasa copolymers.

4. New sinadaran dauki fasahar inganta ta ultrasonic filin

A hade da sabon sinadaran dauki fasaha da ultrasonic filin haɓɓaka aiki ne wani m ci gaban shugabanci a fagen ultrasonic sunadarai.Alal misali, ana amfani da ruwa mai mahimmanci a matsayin matsakaici, kuma ana amfani da filin ultrasonic don ƙarfafa halayen haɗari.Misali, ruwa mai girman gaske yana da yawa mai kama da ruwa da danko da iskar gas kamar gas, wanda ke sanya narkarwarsa daidai da ruwa da karfin canja wurin taro daidai da gas.The deactivation na iri-iri mai kara kuzari za a iya inganta ta yin amfani da mai kyau solubility da watsa Properties na supercritical ruwa, amma shi ne babu shakka da icing a kan cake idan ultrasonic filin za a iya amfani da su karfafa shi.A girgiza kalaman da micro jet generated da ultrasonic cavitation ba zai iya kawai ƙwarai inganta supercritical ruwa don narke wasu abubuwa da kai ga kara kuzari deactivation, taka rawar desorption da tsaftacewa, da kuma ci gaba da kara kuzari na dogon lokaci, amma kuma wasa da rawar motsa jiki, wanda zai iya tarwatsa tsarin amsawa, kuma ya sanya yawan canja wurin taro na halayen sinadarai na ruwa zuwa matakin mafi girma.Bugu da kari, da high zafin jiki da kuma high matsa lamba a gida batu kafa ta ultrasonic cavitation zai zama conducive ga fatattaka na reactants cikin free radicals da kuma hanzarta da dauki kudi.A halin yanzu, akwai da yawa karatu a kan sinadaran dauki supercritical ruwa, amma 'yan karatu a kan inganta irin wannan dauki ta ultrasonic filin.

5. aikace-aikace na high-ikon ultrasonic a biodiesel samar

Makullin don shirye-shiryen biodiesel shine transesterification na catalytic na fatty acid glyceride tare da methanol da sauran ƙananan ƙwayoyin carbon.Duban dan tayi iya a fili ƙarfafa transesterification dauki, musamman ga iri-iri dauki tsarin, zai iya muhimmanci inganta hadawa (emulsification) sakamako da kuma inganta kaikaice kwayoyin lamba dauki, sabõda haka, dauki asali da ake bukata da za a za'ayi karkashin high zafin jiki (high matsa lamba) yanayi. za a iya kammala a dakin zafin jiki (ko kusa da dakin zafin jiki), Kuma rage lokacin dauki.Ultrasonic kalaman ba kawai amfani da transesterification tsari, amma kuma a cikin rabuwa da dauki cakuda.Masu bincike daga Jami'ar Jihar Mississippi a Amurka sun yi amfani da sarrafa ultrasonic wajen samar da biodiesel.Yawan amfanin biodiesel ya wuce 99% a cikin mintuna 5, yayin da tsarin reactor na yau da kullun ya ɗauki fiye da awa 1.
