Wet Abrasive Blasting: An Overview
Sandblasting manufacturers create a variety of blasting equipment for different purposes. Sandblasting is typically used for cleaning, shaping, and polishing various surfaces- often metal. There are several different ways to blast different objects, one of which is wet abrasive blasting.
Wet abrasive blasting is a special type of sandblasting equipment that sandblasting manufacturers create to blast surfaces with fine or coarse media combined with water and soap so that the surface can be cleaned and polished at the same time without the danger of creating hazardous dust and waste. Wet blasting is often used with dangerous substances, such as radioactive materials, poisonous materials, high-dust particles, and asbestos. Wet blasting allows for basic sandblasting techniques without the risk of decontamination.
Usually, no special equipment is necessary for wet abrasive blasting other than a blasting tool that is compatible with liquids. Wet blasting can be done with hand cabinets, automated machines, portable blasting units, and walk-in booths. Wet blasting can be used on more delicate materials because the water acts as a buffer between the media particles and the base surface of the item. It also reduces the possibility of foreign materials sticking to the surface of the object. Because of this, it is the perfect companion to cleaning an object before a coating is placed onto that item.
Most wet blasting procedures include high-pressure water blasting, air and water blasting, and straight wet abrasive blasting. The person completing the blasting task will choose the blasting method based on the needs of the item to be blasted. Even though there are many different styles of wet blasting machines, the most common unit is a cabinet-mounted blasting machine.
