Postup zkou\u0161ky t\u011bsnosti pono\u0159en\u00edm do vody<\/h2>\n\n\n\n

The Zkou\u0161ka t\u011bsnosti pono\u0159en\u00edm do vody<\/strong> zahrnuje pono\u0159en\u00ed n\u00e1doby do roztoku ethylenglykolu a vody v pr\u016fhledn\u00e9 komo\u0159e. Proces za\u010d\u00edn\u00e1 pou\u017eit\u00edm vakua, kter\u00e9 simuluje podm\u00ednky, jim\u017e bude n\u00e1doba vystavena b\u011bhem p\u0159epravy. Zde je rozpis zku\u0161ebn\u00edho postupu:<\/p>\n\n\n\n

    \n
  1. P\u0159\u00edprava zku\u0161ebn\u00edch vzork\u016f<\/strong>
    Zku\u0161ebn\u00ed n\u00e1doby a jejich uz\u00e1v\u011bry se vyb\u00edraj\u00ed n\u00e1hodn\u011b, aby se zajistilo, \u017ee jsou reprezentativn\u00ed pro v\u00fdrobn\u00ed \u0161ar\u017ei.

  2. Aplikace vakua<\/strong>
    N\u00e1doba se pono\u0159\u00ed do zku\u0161ebn\u00ed komory a v komo\u0159e se vytvo\u0159\u00ed vakuum.

  3. Monitorov\u00e1n\u00ed \u00fanik\u016f<\/strong>
    B\u011bhem vakuov\u00e9 aplikace se sleduje, zda n\u00e1doba nevykazuje zn\u00e1mky net\u011bsnosti. Net\u011bsnost se projevuje tvorbou bublin na povrchu n\u00e1doby nebo p\u0159\u00edtomnost\u00ed tekutiny uvnit\u0159 n\u00e1doby po uvoln\u011bn\u00ed vakua.<\/li>\n\n\n\n
  4. Interpretace v\u00fdsledk\u016f<\/strong>
    Pokud je zji\u0161t\u011bn \u00fanik v podob\u011b bublinek nebo tekutiny uvnit\u0159 n\u00e1doby, pova\u017euje se zkou\u0161ka za ne\u00fasp\u011b\u0161nou.
