解させた混合液を給液タンに注入している。In the crosslinked cable manufacturing process, the direct injection method is attracting attention because it eliminates one step compared to the conventional coating method. In this direct injection method, a mixed solution in which a crosslinking agent and an anti-aging agent are heated and dissolved is injected into a liquid supply tank.
しかしながら、架橋剤と老化防止剤との混合液を長時間
加熱していると、架橋剤及び老化防止剤が熱と空気中の
酸素の作用で劣化し、その能力が低下する欠点がある。However, when a mixed solution of a crosslinking agent and an anti-aging agent is heated for a long time, the cross-linking agent and the anti-aging agent deteriorate due to the action of heat and oxygen in the air, resulting in a decrease in their performance.
本発明の目的は、架橋剤及び老化防止剤の劣化を防止し
つつ給液できる押出機への給液方法を提供するにある。An object of the present invention is to provide a method for supplying liquid to an extruder, which can supply liquid while preventing deterioration of a crosslinking agent and an anti-aging agent.

ある。The present invention provides a method for supplying liquid to an extruder through a liquid supply piping while heating and keeping warm a mixed liquid obtained by heating and dissolving a crosslinking agent and an anti-aging agent in the liquid supply tank. The present invention is characterized in that the liquid is supplied while maintaining the atmosphere above the liquid level of the mixed liquid in an inert gas atmosphere.

。なお、１３，１４．１５はバルブである。Above the liquid level of the mixed liquid 2 in the liquid supply tank 1, an inert gas such as N or gas is supplied from a gas supply pipe 6 to maintain an inert gas atmosphere 5 above the liquid level. A predetermined amount of liquid is supplied from the liquid supply tank 1 to the extruder 9 via a liquid supply pipe 7 by the action of a liquid supply pump 8. The liquid supply pipe 7 and the liquid drain pipe 10 at the bottom of the liquid supply tank 1 are each connected with heat-retaining pipes 11 and 12 to collect hot water to prevent precipitation of components in the liquid mixture. Note that 13, 14, and 15 are valves.
