Princip fungov\u00e1n\u00ed sonik\u00e1toru<\/h3>\n

Sonic\u00e1tor pracuje na principu piezoelektrick\u00e9ho efektu, kdy se elektrick\u00e1 energie p\u0159ev\u00e1d\u00ed na mechanick\u00e9 vibrace. Piezoelektrick\u00fd krystal, um\u00edst\u011bn\u00fd v sonik\u00e1torov\u00e9 sond\u011b, generuje ultrazvukov\u00e9 vlny o frekvenci typicky v rozmez\u00ed 20-100 kHz. Tyto vlny se \u0161\u00ed\u0159\u00ed do kapaliny prost\u0159ednictv\u00edm sondy, kter\u00e1 je pono\u0159ena do zpracov\u00e1van\u00e9ho materi\u00e1lu. Intenzita vibrac\u00ed se d\u00e1 regulovat, co\u017e umo\u017e\u0148uje optimalizovat proces pro danou aplikaci. Kolaps kavita\u010dn\u00edch bublin generuje lok\u00e1ln\u00ed vysok\u00e9 tlaky a teploty, kter\u00e9 zp\u016fsobuj\u00ed po\u017eadovan\u00e9 efekty.<\/p>\n
