眾所周知，超(chao)(chao)聲波(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)物(wu)(wu)品優勢明顯(xian)，那么(me)超(chao)(chao)聲波(bo)到底是(shi)(shi)如(ru)何(he)完成清(qing)(qing)(qing)洗(xi)(xi)(xi)工作(zuo)(zuo)的(de)(de)(de)(de)呢？超(chao)(chao)聲波(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)是(shi)(shi)利用(yong)(yong)(yong)(yong)超(chao)(chao)聲波(bo)在(zai)(zai)液(ye)(ye)(ye)(ye)體(ti)(ti)中的(de)(de)(de)(de)空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)、加(jia)速度(du)(du)作(zuo)(zuo)用(yong)(yong)(yong)(yong)及直(zhi)(zhi)進(jin)流(liu)(liu)作(zuo)(zuo)用(yong)(yong)(yong)(yong)對(dui)液(ye)(ye)(ye)(ye)體(ti)(ti)和(he)污(wu)(wu)物(wu)(wu)直(zhi)(zhi)接(jie)、間(jian)接(jie)的(de)(de)(de)(de)作(zuo)(zuo)用(yong)(yong)(yong)(yong)，使(shi)污(wu)(wu)物(wu)(wu)層被(bei)分散、乳(ru)化(hua)(hua)、剝(bo)離(li)而達到清(qing)(qing)(qing)洗(xi)(xi)(xi)目(mu)的(de)(de)(de)(de)。目(mu)前所用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)超(chao)(chao)聲波(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)機(ji)中，空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)和(he)直(zhi)(zhi)進(jin)流(liu)(liu)作(zuo)(zuo)用(yong)(yong)(yong)(yong)應用(yong)(yong)(yong)(yong)得更(geng)多。 （1）空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)：空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)就(jiu)是(shi)(shi)超(chao)(chao)聲波(bo)以每秒兩(liang)萬次以上的(de)(de)(de)(de)壓(ya)縮力和(he)減(jian)壓(ya)力交互性的(de)(de)(de)(de)高頻變(bian)換方(fang)式向(xiang)液(ye)(ye)(ye)(ye)體(ti)(ti)進(jin)行(xing)透射。在(zai)(zai)減(jian)壓(ya)力作(zuo)(zuo)用(yong)(yong)(yong)(yong)時(shi)，液(ye)(ye)(ye)(ye)體(ti)(ti)中產(chan)生真(zhen)空(kong)(kong)(kong)核群(qun)泡的(de)(de)(de)(de)現象(xiang)，在(zai)(zai)壓(ya)縮力作(zuo)(zuo)用(yong)(yong)(yong)(yong)時(shi)，真(zhen)空(kong)(kong)(kong)核群(qun)泡受壓(ya)力壓(ya)碎時(shi)產(chan)生強(qiang)(qiang)大的(de)(de)(de)(de)沖擊力，由此剝(bo)離(li)被(bei)清(qing)(qing)(qing)洗(xi)(xi)(xi)物(wu)(wu)表面(mian)的(de)(de)(de)(de)污(wu)(wu)垢(gou)，從而達到精密洗(xi)(xi)(xi)凈目(mu)的(de)(de)(de)(de)。 在(zai)(zai)超(chao)(chao)聲波(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)過程中，肉(rou)眼能看見(jian)的(de)(de)(de)(de)泡并不是(shi)(shi)真(zhen)空(kong)(kong)(kong)核群(qun)泡，而是(shi)(shi)空(kong)(kong)(kong)氣氣泡，它對(dui)空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)產(chan)生抑制作(zuo)(zuo)用(yong)(yong)(yong)(yong)降低清(qing)(qing)(qing)洗(xi)(xi)(xi)效率。只(zhi)有液(ye)(ye)(ye)(ye)體(ti)(ti)中的(de)(de)(de)(de)空(kong)(kong)(kong)氣氣泡被(bei)完全脫走，空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)真(zhen)空(kong)(kong)(kong)核群(qun)泡才能達到最(zui)佳效果。 （2）直(zhi)(zhi)進(jin)流(liu)(liu)作(zuo)(zuo)用(yong)(yong)(yong)(yong)：超(chao)(chao)聲波(bo)在(zai)(zai)液(ye)(ye)(ye)(ye)體(ti)(ti)中沿(yan)聲的(de)(de)(de)(de)傳播方(fang)向(xiang)產(chan)生流(liu)(liu)動(dong)的(de)(de)(de)(de)現象(xiang)稱(cheng)為(wei)直(zhi)(zhi)進(jin)流(liu)(liu)。聲波(bo)強(qiang)(qiang)度(du)(du)在(zai)(zai)0.5W/cm2時(shi)，肉(rou)眼能看到直(zhi)(zhi)進(jin)流(liu)(liu)，垂(chui)直(zhi)(zhi)于振動(dong)面(mian)產(chan)生流(liu)(liu)動(dong)，流(liu)(liu)速約為(wei)10cm/s。通過此直(zhi)(zhi)進(jin)流(liu)(liu)使(shi)被(bei)清(qing)(qing)(qing)洗(xi)(xi)(xi)物(wu)(wu)表面(mian)的(de)(de)(de)(de)微油污(wu)(wu)垢(gou)被(bei)攪拌，污(wu)(wu)垢(gou)表面(mian)的(de)(de)(de)(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)(ye)(ye)(ye)也產(chan)生對(dui)流(liu)(liu)，溶(rong)解污(wu)(wu)物(wu)(wu)的(de)(de)(de)(de)溶(rong)解液(ye)(ye)(ye)(ye)與新液(ye)(ye)(ye)(ye)混合，使(shi)溶(rong)解速度(du)(du)加(jia)快，對(dui)污(wu)(wu)物(wu)(wu)的(de)(de)(de)(de)搬(ban)運起(qi)著(zhu)很(hen)大的(de)(de)(de)(de)作(zuo)(zuo)用(yong)(yong)(yong)(yong)。 （3）加(jia)速度(du)(du)：液(ye)(ye)(ye)(ye)體(ti)(ti)粒(li)子(zi)推動(dong)產(chan)生的(de)(de)(de)(de)加(jia)速度(du)(du)。對(dui)于頻率較高的(de)(de)(de)(de)超(chao)(chao)聲波(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)機(ji)，空(kong)(kong)(kong)化(hua)(hua)作(zuo)(zuo)用(yong)(yong)(yong)(yong)就(jiu)很(hen)不顯(xian)著(zhu)了，這(zhe)時(shi)的(de)(de)(de)(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)主要靠液(ye)(ye)(ye)(ye)體(ti)(ti)粒(li)子(zi)超(chao)(chao)聲作(zuo)(zuo)用(yong)(yong)(yong)(yong)下的(de)(de)(de)(de)加(jia)速度(du)(du)撞擊粒(li)子(zi)對(dui)污(wu)(wu)物(wu)(wu)進(jin)行(xing)超(chao)(chao)精密清(qing)(qing)(qing)洗(xi)(xi)(xi)。
