Description

Wear-resisting plate suitable for bulk cargo cabin inside lining

Technical Field

The invention relates to the technical field of ship cargo hold loading and unloading protection, in particular to a wear-resisting plate suitable for a bulk cargo hold lining.

Background

Bulk carriers and self-dumping carriers are commonly used for loading ore, sand, grain and other cargo. During the loading and unloading process of the bulk cargo ship, the height difference of the cargo reaching the cabin through the hatch is more than 50 meters. Under the action of gravity and height, goods fall from top to bottom to impact steel plates in the cabin, so that paint on the surfaces of the steel plates falls off and is corroded by seawater easily. And is subject to breakage during long-term use resulting in permanent non-repairable damage. The laying application of the wear-resisting plate solves the problem that the steel plate is damaged due to long-term loading and unloading, and is easy to clean in the cabin. Plates made of ultra high molecular weight polyethylene (UHMW PE) are laid inside the hull of conventional bulk carriers and bulk self-discharging vessels, and laid and fixed on steel plates inside the cargo tanks. In the process of loading and unloading goods, the damage of the steel plate of the cabin caused by the impact of the goods is avoided. The wear-resisting plate is applied to bulk cargo ships and bulk cargo self-discharging ships with a cabin cover and without the cabin cover. The ship with the hatch cover is mostly paved by using a pure UHMW PE plate. The ship without the cabin cover is paved by adopting an anti-UV plate. However, the steel plate body at the bottom of the existing cabin is large in size, and once the steel plate body is damaged, the replacement cost is high, and the maintenance is troublesome.
