Hydroblasting Robot

Hydroblasting Robot Working Principle

The ship hull rust removal robot designed by AKA Robotics utilizes a magnetic climbing robot as its carrier, equipped with an ultra-high-pressure water jet cleaning disc to achieve rapid rust removal and paint stripping. The waste water and residue generated during the rust removal and paint stripping process are processed using a vacuum recovery machine, achieving the goal of reducing emissions and promoting environmental protection through recycling.

What is Hydroblasting and UHP Water Blasting?

Hydroblasting is a cleaning method that employs high-pressure water to eliminate dirt, rust, paint, scale, and other impurities from surfaces. 

UHP (Ultra-High Pressure) Water Blasting is a type of hydroblasting that uses extremely high water pressure, usually greater than 1,700 bar (25,000 psi). UHP water blasting is extensively used in shipbuilding, oil and gas, and infrastructure maintenance to remove thick coatings, heavy rust, or scale.

Water Blasting vs Sandblasting

Both water blasting and Sandblasting are two of the most common methods for coating removal and surface cleaning. Here's a comparison:

Aspect	Water Blasting	Sandblasting
Medium Used	Uses high-pressure water. Abrasive materials like sand or garnet can be used for better performance, but water is primary.	Uses compressed air and sand (or other abrasives) to clean surfaces.
Environment and Safety	More environmentally friendly, uses water, no dangerous dust or particles. Vacuum suction tech collects and processes wastewater and paint debris.	Generates waste (abrasive materials, dust) that can harm workers and the environment.
Surface Impact	Causes less surface damage; impact is milder and adjustable to protect delicate textiles.	More abrasive, may cause wear or damage, especially on softer materials. Changes surface texture.
Cleaning Efficiency	Highly effective for rust, paint, grease, and other pollutants, without damaging substrate. Great for fragile surfaces.	More effective for tough coatings, corrosion, and debris removal, but harsher on sensitive materials.
Applications	Used in shipbuilding, pipeline cleaning, industrial equipment maintenance, paint/coating removal, and cutting soft materials.	Used in surface preparation for painting, coating, welding, and heavy-duty cleaning of metal, concrete, and stone.
