  The rise of world powers all starts with shipbuilding and follows the ocean. As an important symbol of a country's industrial level, the shipbuilding industry, as the "crown of comprehensive industry", has a high degree of industrial expansion and strong industrial driving. Since the first half of this year, the shortage of global transportation capacity has led to a rise in shipping prices, and the growth in shipping demand has led to an increase in international new ship orders, giving birth to a "prosperity scene not seen in a decade" in the global shipbuilding industry. China's shipbuilding industry has risen concurrently against the trend, and the shipbuilding repair and shipping industries are basically good.

  In ship repair, there are a large number of cleaning links, mainly including steel plate pretreatment (before welding and after welding) and segmented pretreatment (before painting) for new ships, as well as rust removal, overall paint removal and secondary painting maintenance for old ships.

  Among them, the common rust removal methods of ships include manual rust removal, mechanical rust removal and chemical rust removal. Laser cleaning and rust removal will be developed and applied as a new technology.

  1. Manual rust removal

  Manual rust removal tools include hammers, spatula, steel knives, wire brushes, etc. Generally, thick rust spots are loosened with a hammer and then shoveled with a spatula. High labor intensity and low rust removal efficiency.

  2. Mechanical rust removal

  (1) Small pneumatic or electric rust removal; (2) Shot peening (sand) rust removal;

  (3) High-pressure water abrasive rust removal; (4) Shot blasting rust removal.

  3. Chemical rust removal

  It is mainly a rust removal method that uses acid to chemically react with metal oxides to remove rust on the metal surface, which is usually called pickling and rust removal. It can only be operated in the workshop. Chemical rust removal has high risk and serious environmental pollution. It is used in restricted grades.

  4. Laser rust removal

  Laser rust removal is a new green, environmentally friendly, efficient and safe new technology that will soon replace the above processes and be widely used. Especially in paint removal, oil removal, corner cleaning and rust removal, oxide removal, etc., laser cleaning will play an irreplaceable role.

  Laser cleaning technology has many advantages such as no damage to the substrate, precise control, energy saving and environmental protection, and can fully meet the needs of rust removal of all steel plate profiles, as well as pretreatment before and after welding. In the maintenance of ships, laser cleaning is a "high-precision" cleaning technology, which is suitable for the peeling of rust and paint on the surface of cabins, ballast tanks, fuel tanks, etc., as well as the cleaning of carbon deposits such as marine diesel engine cylinder valves. It does not damage the substrate, and can deal with fine gaps without obstacles. Accurate descaling, high cleaning quality, energy saving and environmental protection.
