따라서, 본 발명에 의해 제조된 해저 케이블 보호관용 폴리우레탄 조성물은 해수의 저면에 잘 가라앉아 보호관 설치작업의 효율성이 높고, 해수에 장기간 노출되어도 물성이 유지되는 것을 알 수 있다.Therefore, it can be seen that the polyurethane composition for submarine cable protective tube manufactured according to the present invention sinks well on the bottom of the seawater, so that the efficiency of the protective tube installation work is high, and the physical properties are maintained even when exposed to the seawater for a long time.
본 발명에 따른 해저 케이블 보호관용 폴리우레탄 조성물은 유연성이 부여되어 해수의 유동이나 외부에서 가해지는 충격으로부터 균열이 억제되는 탁월한 효과를 나타낸다.Polyurethane composition for submarine cable protective tube according to the present invention has the excellent effect that the flexibility is imparted, the crack is suppressed from the flow of the sea water or the impact applied from the outside.
또한, 고밀도의 재료를 사용하여 해저의 저면에 잘 가라앉기 때문에 보호관 설치시 작업효율을 향상시키는 탁월한 효과를 나타낸다.In addition, because the high density material is used to sink to the bottom of the seabed, it shows an excellent effect of improving the work efficiency when installing the protective tube.
또한, 산화방지제, 자외선 안정제 및 난연제를 사용하여 자외선 및 전력케이블에서 발생하는 스파크로 인한 보호관의 물성저하가 억제되는 탁월한 효과를 나타낸다.In addition, by using an antioxidant, a UV stabilizer and a flame retardant exhibits an excellent effect of reducing the physical properties of the protective tube due to the spark generated from the ultraviolet and power cables.
