Conclusions
-
1.
A study of the structural characteristics of PGMs produced by rolling packs of one-sided sergewoven Kh18N10T steel gauzes has demonstrated that they are determined by the structure of the starting gauzes and the degree of pack deformation during rolling.
-
2.
It has been established that expressions relating the coefficient of relative compression, porosity, and pore size of a PGM to one another make it possible to calculate suitable process parameters for the production of PGMs of predetermined structural characteristics.
-
3.
The hydraulic resistance of PGMs has been determined; it is shown that the pressure loss experienced by a fluid during its filtration through a PGM is determined chiefly by the degree of deformation of the starting gauze pack.
