A plant for making continuous yarns (30) made of silicon material comprises at least an extrusion station (12), into which the material is introduced in an amorphous condition, and extrusion means (15) which cause the material to exit from the extrusion station (12) along an extrusion axis (D). The plant also comprises a vulcanization station (16), located downstream of the extrusion station (12), at a determinate distance (“L”) therefrom, in which the continuous yarn (30) is vulcanized in a direction of treatment (T). The plant also comprises a drawing unit (18), disposed downstream of the vulcanization station (16).
摘要:
The present invention is a method for degassing an electrical cable having a crosslinked, semiconductive shield layer prepared from a composition made from or containing (i) a phase I material consisting essentially of a polar copolymer of ethylene and an unsaturated ester having 4 to 20 carbon atoms, (ii) a phase II material consisting essentially of a nonpolar, low density polyethylene, and (iii) a conducting filler material dispersed in the phase I material and/or the phase II material. The degassing temperature is greater than 70 degrees Celsius.
摘要:
A continuous gas baking furnace comprising means for heating a baking area (29) through which the product which is to be treated passes, formed by at least one module (1, 2, 3, 4) comprising a heat exchanger (13, 14, 15, 16) with a gas burner (5, 6, 7, 8) and means (32, 33, 35, 36, 41, 42) for propelling and directing heated air towards a baking area (29), wherein the gas combustion circuit of the heat exchanger is separate from the circuit of hot air flowing through the baking area, the means for directing the hot air include paths (38,39) for directing hot air on both sides of the baking area (29) and a path (40) for evacuating air via the middle of the baking area. The invention is characterized in that it also comprises means for ensuring pyrolysis of gaseous effluents, said means treating a fraction of the gas circulating in a given section of the furnace, and at least one catalytic bed (76, 76') which is arranged on the hot air circuit.
摘要:
The present invention relates to a sleeve (30) for use in vulcanization process. The sleeve has a cylindrical shape and is constructed of an elastomeric composition comprising a cross-linked rubber and from 5 to 50 phr of chopped carbon fibers (36).
