Polymeric meshes. Part 3. Mesh technological lines and units

Abstract

The basic stages of the most widespread methods of manufacture of polymeric meshes by direct formation of a cloth of meshes by extrusion are considered. The analysis of work of a technological line of manufacture of nodeless polymeric meshes by extrusion of melt through apertures in rotating in opposite directions coaxial-located draw plates, and also extrusion head of this line extruder is made. The device and a principle of work of other type’s technological lines of domestic and foreign manufacturers are considered. Also work of experimental installation on the basis of one-screw extruder for formation a sleeve polymeric mesh from low density polyethylene is considered. The analysis of influence of melt temperature on durability of strands connection of workpiece mesh is made. The optimum temperature of melt for making of a quality mesh is defined.
