Description
Technical Field
The invention relates to a device and a method for preventing easy-to-fluidize goods for shipping of a high water-absorption polymer, belonging to the technical field of marine transportation.
Background
International maritime solid bulk cargo regulations (IMSBC regulations) have currently been enforced which govern the three groups A, B and C for the on-board solid bulk cargo. Wherein, the A group of goods are the easy-to-flow goods. The water-retaining agent is composed of a certain proportion of fine particles and a certain amount of water, and when the water content of the water-retaining agent exceeds a certain level during marine shipment, fluidization can occur so as to form a fluid state. After the goods are fluidized, the viscosity and the density are high, the stability of the ship can be weakened by the transverse movement of the goods in the cargo hold, the ship is transversely inclined, and the ship can overturn under severe conditions.
In the process of shipping the easy-flowing goods, because the ship vibrates and swings, the gap between the goods is reduced, the surface of the goods gradually seeps water to form a free liquid level, and meanwhile, the internal pore water pressure of the goods rises to cause the shear strength loss of the goods, namely, the goods move to cause the transverse inclination of the ship.
The occurrence of fluidization of the goods is closely related to the water content of the goods, so that the fluidization of the goods easy to fluidize can be prevented by a method for reducing the water content. At present, no device and method for reducing the internal water content of the easy-to-flow goods by adopting the super absorbent polymer are discovered.
