DEVICE FOR DETERMINING ADHESION STRENGTH OF POLYMER DISPERSED SELF-HARDENING COMPOSITES Russian patent published in 2019 - IPC G01N19/04 

FIELD: test.

SUBSTANCE: invention relates to test equipment, in particular to determination of adhesive adhesion strength of polymer-dispersed self-hardening composites. Device consists of matrix, which is fixed in internal part of massive holder, and rod, having cylindrical shape, for extrusion of composite. Matrix is replaceable element and represents hollow cylinder with support collar in upper part, with thread cut at outer surface with fine pitch, and inner cavity is intended for formation of experimental composite. Support collar is made with two opposite flats for wrench. On the cartridge inner surface thread with fine pitch corresponding to matrix thread pitch is cut by a length slightly larger than the matrix height, and the outer diameter of the cartridge is at least 3 times greater than the diameter of the hole in the matrix, wherein the upper part of the rod has diameter 1.5 times greater than the diameter of the forcing part.

EFFECT: technical result is wide universality of device; high quality of research, required reliability of results in the presence of a large number of parameters studied in one test cycle.
