METHOD OF MANUFACTURING ORDINARY TEMPERATURE SHRINKAGE RUBBER INSULATION TUBE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an ordinary temperature shrinkage rubber insulation tube capable of minimizing degradation of electric characteristics due to mixing of foreign matter, or the like.;SOLUTION: An inner semiconductor layer production apparatus 10 is constituted of tanks 11a, 11b, pumps 13a, 13b, a mixer 15, a mesh 17, molds 19a, 19b, and the like. An inner semiconductor layer 3 is molded of a two-liquid mixing type liquid silicon rubber. For example, an A agent produced by adding a platinum compound, as a catalyst, to a base rubber is stored in the tank 11a. A B agent produced by blending a crosslinking agent to a base rubber is stored in the tank 11b. The A agent and B agent are sucked by means of the pumps 13a, 13b, so as to become a predetermined ratio, and then mixed by means of the mixer 15. The material thus mixed is cast in the molds 19a, 19b through the mesh 17. Preferably, the mesh 17 has an opening of 43-70 μm.;COPYRIGHT: (C)2015,JPO&INPIT
