Method of forming and positioning brittle gels samples used to determine the dynamic modulus of elasticity and the research position to determine these modules

摘要

method of forming and positioning samples brittle gels, especially silicate gels used to designate their dynamic modules of elasticity, characterised by the fact that the wykrojnika (5) is inserted, by vacuum ranging from 2% to 5% of the absolute pressure her free sample test gelthe forming cylinder (6) of diameter corresponding to the diameter of the parallel bases and sockets (8) on the bottom, the measuring sensor (4), and then, under the pressure of from 2% to 5% of atmospheric pressure, the sample out on a flat plate (9) position of ba dawczego and moves across the upper surface of the plate (9a) to the nest (8) on the bottom, the measuring sensor (4),then leaves the sensor (7), so don't take my word on top of the sensor (4), the sample (6), charging luz between sample and sensor, designated thickness dividers pad (2) test.the research for dynamic elastic modules has a band to the fragile brittle gels sample (6) and its axial positioning of sensors (4, 7), composed of a lower plate (9), fixed with respect to the base (1), a test bench the flat upper surface (9a), protruding one end outside the sensor.on the surface of pristine dividers pad (2) of a thickness greater than that of the sample and on the other pad (10) with a transverse hole in the sensor (7), whereby the lateral hole is wspu00f3u0142osiowy hole on the sensor (4) and the socket (8) issued in the bottom plate (9) and the basis (1) the test bench.
