The wetting angle of the solid is used to calculate the equilibrium work of adhesion according to:
Wa = /LVo (1 + CoS Θ), kde Θ je ' uhol ' zmáčania zmeraný pomocou goniometra, /lvo je povrchové napatie testovacej kvapaliny v prostředí jej nasýtených pár.Wa = / LVo (1 + CoS Θ), where Θ is the 'wetting angle' measured by the goniometer, / lvo is the surface tension of the test liquid in its saturated vapor environment.
‘Princip merania uhla zmáčania na mikroskopickom goniomtfri spočívá v jeho určení zo zváčšeného obrazu kvapky kvapaliny, pričom1 je uhol zmáčania vymedzený povrchom tuhej látky a dotyčnicou ku kvapke kvapaliny. Nevýhodou používaných prístrojov na. meranie uhla zmáčania je. obtiažnosť, resp. nemožnost merania dynamických rastúcich . a . klesajúcich uhlov zmáčania.The principle of measuring the wetting angle on a microscopic goniometer is to determine it from an enlarged image of a liquid droplet, wherein 1 is the wetting angle defined by the surface of the solid and tangent to the liquid droplet. The disadvantage of the devices used for. measuring the wetting angle is. difficulty, respectively. impossibility to measure dynamic increasing. a. decreasing wetting angles.
Uvedené nedostatky odstraňuje přístroj, ktorého podstata spočívá v tom, že na nástavbo binokulárneho tubusa je otáčavo zabudovaný merací okulár okalibrovaný do 180° s vytvořeným vloženým, pohyblivým nitkovým krížom a meracia komórka je připevněná pružinou k uholníkom, ktoré sú priskrutkované k otáčavému kruhovému stolčeku' s vytvořenou stupnicou ' do 360°, pričom pohyblivý nitkový kříž meracieho okulára je vytvořený na planparalelnej dostičke pohyblivo vloženej do optickej sústavy meracieho okulára tak, aby bolo možné súčasné zaostrenie pohyblivého nitkového kríža a stabilného .nitkového kríža binokulárneho tubusa, pričom meracia komórka pozostáva zo spodnej časti s rezervoárom testovacej kvapaliny a s dostičkou z nehrdzavejúcej ocele so vzorkou tuhej látky a z hornej časti s dvorná zasklenými kruhovými priezormi zafixovanými mosadznými prstencami.The above-mentioned drawbacks are eliminated by an apparatus which is based on the fact that the binocular tube is fitted with a rotatably mounted 180 ° calibrated eyepiece with an inserted movable crosshair and the measuring chamber is spring-fastened to angles which are screwed to the rotating round table formed by a scale of up to 360 °, wherein the movable eyelet of the measuring eyepiece is formed on a planar parallel plate movably inserted into the optical assembly of the eyepiece so as to permit simultaneous focusing of the movable eyelet and the stable crosshair of the binocular tube. with a test liquid reservoir and a stainless steel suffix with a solid sample and a top with courtyard glazed circular visors fixed with brass rings.
Výhodou mikroskopického goniometra na meranie uhlév zmáčania tuhej látky kvapalinou je jeho jednoduchost, vysoká přesnost a reprodukovatefnosť meraní dynamických rastúcich a klesajúcich uhlov zmáčania otáčaním kruhu s vytvořenou stupnicou, ku kitorému je upevněná ' meracia . komórka, okolo horizontálnej osi.The advantage of the microscopic goniometer for measuring solids wetting wetting solids is that it is simple, high accuracy, and reproducible to measure dynamic increasing and decreasing wetting angles by rotating the scale-formed circle to which the measurement is attached. chamber, about the horizontal axis.
