摘要:
The present invention relates to a process of applying metal microparticles to polymeric material, based on fusing metal particles to the surface of the polymer. The process is characterised in that fragmented metal particles in the form of micrometre-sized powder are premixed with a granulate of a polymeric material, and subsequently, at continued stirring, the metal particles are heated by eddy currents generated by a rapidly changing magnetic field. The present invention also relates to a device for performing the process, a polymeric material with metal microparticles and the use of the polymeric material.

The invention relates to a valve of a filling-emptying channel with an elastically deformable element. A valve of a filling-emptying channel of a container with an elastically deformable element, according to the invention characterised in that the valve body (1) of the filling-emptying channel placed in the container wall, has a ring (2) with a centrally located boss (3), with a hole (4) for the conical part (6) of the elastically deformable element in the form of a valve plate (5). The ring (2) is mounted on at least two arms (7), which join it to the inner surface of the valve body in the filling- emptying channel. The elastically deformable valve plate (5) closing the filling-emptying channel has the shape of a cup of variable thickness with a circumferential narrowing (8) for reversing the convexity of the shield (9), and, in the lower part, it has a conical part 6 for guiding the ring (2) into the hole (4) in the valve body (1).
