Recently, China's fishery administration system has the largest tonnage and the most technologically advanced flagship ship – the 3,000-ton fishery government ship of the Donghai District Fishery Bureau of the Ministry of Agriculture started construction at the Wuchuan Group.
The 3,000-ton fishery vessel in the East China Sea is a full-rotation pod-type electric propulsion ship, which was adopted for the first time in the domestic fishery series. The ship is an order for the fishery ship that was seized again after the construction of a 1,000-ton fishery government ship 10 years ago. For the construction of the ship, Wuchuan will combine years of experience in the construction of official ships and electric propulsion ships to continuously strengthen process control, promote “five fines†management, and strictly control quality, and build the 3,000-ton electric propulsion fishery ship in the East China Sea into performance. Excellent boutique ship serving the national marine fishery.
Generally, the petroleum resins are not used independently, but have to be used together with other kinds of resins as promoters, adjusting agents and modifiers in hot-melt adhesive, pressure-sensitive adhesive, hot melt road marking paint, rubber tires and so on.
The flagship ship of China's fishery administration system was built in Wushu
