Wet abrasive blasting offers a number of benefits over not only manual processes as well as over dry sandblasting.
Abrasive and water are usually mixed within the blast tank. During the process, water will encapsulate both the abrasive and coating being removed. The trapped abrasives are no longer airborne, and they end up falling to the ground leaving the surrounding environment free from the mess.
The fact that water is combined with the abrasive means that there will be no ignitable sparks or dust plumes. So blasting can be done even in open surroundings or in the presence of other workers nearby. Furthermore, the business will save more money on cleanup and containment costs.
The system is fully mobile and can be easily transported. So permanent fixtures or large structures like pipelines and bridges can still be taken care of using wet abrasive blasting.
Efficient and safe
Contrary to traditional sandblasting, the use of water leads to lower levels of toxic dust plume. Due to this, it is not essential to wear heavy protection such as a full blast suit for protection from dust and particles. The risk of dust inhalation is much lower. In addition, there is the added benefit of comfort and productivity as it increases visibility, ability to manoeuvre while diminishing the risk of accidents.
The process requires less volumes of compressed air, and thus a much smaller compressor can be used compared to its dry blasting counterpart.
The system is safe for the environment, generates no ignitable sparks, and is easy to contain. Therefore, it is the most preferred tool for working in offshore rigs, live pipelines, as well as in residential or populated areas as people around continue with their daily activities.
Needs less abrasive
Combining the abrasive and water generates more mass and a higher force used in the blasting process. This will allow the operator to work more efficiently while utilising less abrasive. In turn, this will speed up production time and cut on any associated consumable costs.
Friendly to cars
Another crucial benefit is that wet blasting has less friction heat and does not dent/wrap thin metals like bonnets as much. Consequently, this is the ideal paint stripping method in the automotive restoration sector.
Increased lifespan of the equipment
The abrasive stays lubricated by the water as it moves through the pot, hoses, and nozzles. This will reduce wear and tear as well as heat transfer in your equipment. Consequently, there is no downtime for maintenance and the equipment lasts much longer.
Dry blasting is permitted in contained booths only because the dust and chemicals generated can spread over a large area. On the other hand, the water in wet abrasive blasting traps the dust and it falls to the ground. As an example, if a car were to be blasted in the centre of a football field, the dust from dry blasting would cover the entire field whereas with wet abrasive blasting, it would be contained just to the centre circle.
