Media blasting is a surface treatment process that involves the use of an abrasive media forced through a blasting nozzle by compressed air. While sand was a popular abrasive media, it is no longer used due to health concerns and the risk of inhaling silica particles. Steel and ceramic grit, crushed glass, plastic beads, glass beads, aluminum oxide, and copper slag have replaced sand to strip off the surface of a target. The process is similar to a pressure wash but is used to prepare surfaces for high-performance coatings and treat products that require luster and a particular surface texture. The equipment used varies according to the size of the operation. Several types are ranging from hand cabinets to high-speed production models and robotic systems.
Media blasting equipment usually consists of an air compressor, blaster nozzle, and the abrasive. The process is carefully controlled with alternate air supply, ventilation, and protective gear. In addition to cleaning surfaces, the method can be used to etch and carve designs on glass and other materials. The process involves focusing an air-powered pressure gun with a ceramic barrel that forces the abrasive out at high velocity on the intended surface. There are typically three types of media blasters, which include gravity-fed models, pressure blasters and siphon sandblasters. One of the essential pieces of media blasting equipment is the blast cabinet which features armholes for the operator to place his hands inside. Pressure blasters are usually portable and vary in size and power and are easier to use than other models. While these machines are cheap on cleaning and maintenance the abrasive fired out cannot be collected and reused.
The gravity fed model features an air compressor; hand held pressure gun with an air hose and a hopper filled with abrasive. Pressure blasters are used in industries and consist of a large canister filled with rough under high pressure. A sandblasting gun is connected to the cartridge through a hose. Siphon sandblasters are used to clean and strip large surfaces. They feature a blasting gun with one tube attached to the handle and the other to the underside of the barrel, along with a pressured tank or air compressor and a reservoir of abrasive. The air creates suction when the gun is fired, which in turn pulls the abrasive from the tank into the gun and is shot out of the barrel. The abrasive that is fired can be reused by placing it back in the reservoir.
Why should you get the bottom of boat media blasted? The first and foremost reason is a growth of bottom paint over some years that the vessel has been enameled. This coating or paint beefs up non-needed weight to the vessel, and at one point of time, there is a lot of paint leading chunks to peel turning the bottom rough and bumpy finally resulting in the boat having more drag. Furthermore, if you are already facing this flaking issue and paint does not appear to sheep along the vessel, this suggests that something was done falsely when the paint was used the very first time.
Media Blasting services enables you to have a new start and to ensure the products you or the yard utilizes are used in a proper way. A new boat owner can get their boat bottom blast-cleaned to see what they have bought. Underneath issues which could have been hidden can be quickly addressed, and right coats and processes can be pursued when reapplying the bottom paint. This can lend you the peace of mind that your boat bottom will work perfectly as it must for multiple years to come. Whatever be the reason for cleaning of marine surfaces, media blasting will make sure that the bottom paint is stripped smoothly and more efficiently.
