The advantages are that the water traps the dust produced, and lubricates the surface. Wet abrasive blasting uses water as the fluid moving the abrasives. Boron carbide is a popular material for nozzles because it resists abrasive wear well. Nozzles come in a variety of shapes, sizes, and materials. The mixture travels through a hand-held nozzle to direct the particles toward the surface or work piece. Sandblasting equipment typically consists of a chamber in which sand and air are mixed. Thomas Wesley Pangborn perfected the idea and added compressed air in 1904. An artificial sandblasting process was patented by Benjamin Chew Tilghman on 18 October 1870. Sandblasting can occur naturally, usually as a result of particles blown by wind causing aeolian erosion, or artificially, using compressed air. Sand blasting is also known as abrasive blasting, which is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies. In addition, there are alternatives that are barely abrasive or nonabrasive, such as ice blasting and dry-ice blasting. A mild version is sodablasting (with baking soda). Some of these substances can cause anaphylactic shock to individuals allergic to the media. Moderately abrasive variants include glass bead blasting (with glass beads) and plastic media blasting (PMB) with ground-up plastic stock or walnut shells and corncobs. The most abrasive are shot blasting (with metal shot) and sandblasting (with sand). There are several variants of the process, using various media some are highly abrasive, whereas others are milder. The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often called the media). Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. beach in Avalon…the bell of the ice cream man ringing on the end of the beach path….A corrosion pit on the outside wall of a pipeline at a coating defect before and after abrasive blasting (Mine was bubblegum….takes me right back to 15th St. It is a basic simple syrup recipe….with just 2 add in’s….a touch of fresh lemon juice and your flavoring of choice. Keep in mind, these are little 1 tsp doses…but it will make 2 full cups of water ice.Ĭups: These make it handy to store in freezer….and make several flavors:)Īnd here is the ice cream maker I have….I love it! This is the key to getting the consistency of true water ice…very smooth and silky. I ordered bubblegum, root beer, watermelon and coffee. Like I said….this is really simple to make….but a little forethought is needed:)įlavoring (this is an amazon affiliate link) They have over 40 flavors. Also, it helps to have some individual containers that you can scoop the water ice in to freeze hard. The flavoring I ordered online…and you have to use an electric ice cream maker to get the perfect consistency. Now…let me just say this….you gotta want it. I believe I perfected it….traditional Philly water ice…right here in the Bluegrass….love ) I was on a mission to share this summer time treat with my kids. There is a certain texture…not chunky ice like a snow cone….not shaved ice…but smooth ice…similar to the texture of ice cream….but without the cream. You would think that a simple sugar syrup and a little bit of flavoring wouldn’t be too hard to come by….but it is. There are several things that remind me of childhood…water ice is real high on that list.
