Amandla e-Ultrasonic asebenza kwi-medium, eya kubangela ukuba iinqununu zishukume ngesantya esiphezulu kwaye zivelise utshintsho lomatshini njengesantya, ukukhawuleza, uxinzelelo lwesandi, kunye nobukhulu besandi, ngaloo ndlela kubangele imiphumo yomatshini. I-Ultrasound yindlela yokusabalalisa amandla omatshini, ehambelana nenkqubo yamaza kwaye iya kuvelisa umphumo womgca wokungcangcazela. Xa i-ultrasonic wave isasaza phakathi, nangona i-amplitude ye-particle displacement encinci, ukukhawuleza kwe-particle ebangelwa yi-ultrasonic wave inkulu kakhulu.
Ukuba i-20kHz, i-1W / cm2 i-ultrasonic wave isasazeka emanzini, i-amplitude yoxinzelelo lwesandi eveliswa yiyo yi-173kPa, oku kuthetha ukuba i-amplitude yoxinzelelo lwesandi kufuneka itshintshe amaxesha angama-20,000 phakathi kwe-173kPa enhle kunye ne-173kPa ngesekhondi, kunye neyona nto iphakamileyo yokunyusa i-particle ukuya kwi-1440km malunga ne-1250km malunga ne-1250km. umxhuzulane, ukunyakaza okunzulu kunye nokutshintsha ngokukhawuleza komatshini yimpembelelo ye-vibration yomatshini yamandla e-ultrasound.
Xa i-ultrasonic medium ingeyiyo i-uniform layered medium (efana ne-biological tissue, umzimba womntu, njl.), i-acoustic impedance yoluhlu ngalunye lwemidiya iya kubangela ukuba amaza omsindo abonakalisiweyo abonise kwaye enze i-wave wave. I-antinodes kunye neenodi zamaza omileyo zibangela uxinzelelo kunye noxinzelelo kunye nokutshintsha kwesantya. Ekubeni ubunzima beengqungquthela zeendaba ezahlukeneyo (ezifana ne-biomolecules) zihluke, isantya sokungcangcazela esibangelwa utshintsho loxinzelelo luhluke, kwaye ukutshintshwa koxinzelelo olubangelwa ukunyakaza okuhambelanayo phakathi kweengqungquthela zeendaba sesinye isizathu somphumo we-ultrasonic mechanical. Iimpembelelo zomatshini usebenzisa i-ultrasound kufuneka zicutshungulwe (i-perforation, cutting, compaction, i-surface yokuqinisa, i-welding, ukucocwa, ukupolisha, kunye nokususwa kweefilimu ezingathandekiyo kunye nokungcola, njl.), kwaye kusetyenziswe ukukhawulezisa ukusabalalisa, i-homogenization, i-emulsification, kunye nokutyumza , Sterilization kunye nezinye iinkqubo.
Umphumo womatshini we-ultrasound usetyenziswe ngokubanzi kwimveliso, kwaye imizekelo ilandelayo.
Ukuphazamiseka koomatshini
I-Ultrasonic high-frequency vibration kunye noxinzelelo lweradiation inokwenza uphazamiseko olusebenzayo kunye nokuhamba kwigesi kunye nolwelo. Ijethi eyomeleleyo kunye nokuhamba kwe-micro-rush yasekhaya eveliswa yi-vibration bubble ye-cavitation kwindawo eqinileyo inokunciphisa ngokuphawulekayo ukunyanzeliswa komphezulu kunye nokukhuhlana kolwelo, kwaye itshabalalise umaleko oqhotyoshelweyo wojongano oluqinileyo-ulwelo, ngoko ayikwazi ukufikelela kwi-agitation ye-mechanical low-frequency mechanical. isiphumo. Esi siphumo sisisiseko somzimba sokusetyenziswa kweziyobisi ngolusu lomntu, iimveliso zobuhle eluswini lomntu, i-ultrasonic degassing, ukutya kunye ne-cosmetic leveling kunye nokulungiswa.
Ukudibanisa
Uxinzelelo kunye nobushushu obuphezulu befuthe le-ultrasonic vibration kunye ne-cavitation zisetyenziselwa ukukhuthaza ukungena ngokubambisana kweeamolekyu phakathi kwee-liquids ezimbini, ezimbini eziqinileyo, okanye i-liquid-solid kunye ne-liquid-gas interfaces ukwenza izinto ezintsha zezinto eziphathekayo. I-Ultrasonic welding yesinyithi okanye iiplastiki, i-ultrasonic emulsification, ukucoca, i-atomization ingahlelwa njengemiphumo enjalo.
Homogenize
Emva kokuba i-bubbles ye-cavitation ivaliwe, i-wave shock wave iyakwazi ukutyumza iincinci kwi-liquid ukuze ihambe kakuhle; yenza iyunifomu yekristale; sasasaza amathontsi obisi amakhulu kunye nokungalinganiyo kwii-agent ezincinci ezifanayo (ezifana nee-agent ezichasene zonyango, ii-arhente zonyango zomhlaza, njl.); Inokuquka i-thrombolysis kunye nezinye iziphumo.
Umanyano
I-Ultrasonic vibration inokwenza iinqununu ezimisiweyo kwi-gas kunye ne-liquid medium zihamba ngezantya ezahlukeneyo, ukwandisa ithuba lokungqubuzana kwesigaba; okanye ukusebenzisa amaza amileyo ukubenza bathambekele kwii-antinodes, ngoko ke inkqubo ye-agglomeration iyenzeka. Ukuqokelelwa kothuli kwiflue kunye nemvula eyenziweyo iwela kolu didi.
Isenzo sokusika oomatshini
Ngenxa yokukhawuleza okukhulu kwe-vibration ye-ultrasonic kunye nomphumo we-cavitation kunye ne-acoustic corrosion, ukucutshungulwa okukhethekileyo kunye nokuchanekileyo kwezinto ezinzima kunye ne-brittle (amagugu, i-ceramics, iglasi, insimbi yamagnetic, njl.) inokwenziwa.
Smash
Ukusetyenziswa kwe-high-intensity ultrasound pulses kunokutyumza amatye ezintso kunye ne-gallstones emzimbeni ngaphandle kokonakalisa izicubu ezithambileyo.
