Abstract
Inventia se refera la o metoda si un aparat pentru masurarea aderentei emailului pe tabla. Metoda conform inventiei consta în explorarea contactelor electrice stabilite pe o suprafata de proba, modificata, de un numar de ace. toate acele apasînd pe întreaga suprafata de proba cu o presiune constanta, de preferinta de 0,3...0,6 N, iar deformarea mecanica, de preferinta a suprafetei testate realizîndu-se printr-un procedeu de ambutisare adînca, cu o forta de încastrare definita, cu o viteza de ambutisare constanta si un traseu de ambustisare dat. Aparatul este constituit dintr-un dispozitiv de masurat prevazut cu ace, un dispozitiv de numarare pentru înregistrarea numarului contactelor electrice stabilite si o legatura electrica dintre ace si dispozitivul de numarare acele fiind dispuse într-un suport comun de genul unei penite pentru ace, paralele între ele un unghi si fiind egal distantate între ele, iar acele cu aceasi lungime fiind dispuse într-un hexagon centrat în jurul punctului central comun al suportului punctul central al suaportului comun fiind lipit de ace.The invention relates to a method and apparatus for measuring the adhesion of the email on the board. The method according to the invention consists in exploring the electrical contacts established on a sample surface, modified by a number of needles. all the presses pressing on the whole sample surface with a constant pressure, preferably of 0.3 ... 0.6 N, and the mechanical deformation, preferably of the test surface being realized by a deep drawing process with a force defined embedding with a constant drawing speed and a given trajectory. The apparatus comprises a measuring device provided with needles, a counting device for recording the number of electrical contacts established, and an electrical connection between the needles and the counting device, those being arranged in a common support such as a needle pen, parallel to each other being angled and equally spaced apart, and those of the same length being disposed in a hexagon centered around the common center point of the support, the central point of the common saport being attached to the needles.
