What is Sandblasting High-pressure injection of sand or stainless steel shots on metallic surfaces using a machine called ‘sand blasting machine’ in order to smoothen, clean and mainly to remove rust of the same.

How sand blasting machine works They consist of a large canister containing sand under high pressure. This is a bit similar to the concept behind an aerosol can. A sandblasting gun, usually a two-handed model, is connected to the port at the top of the canister by means of a specialized hose that can withstand the abrading affects of the sand. When the trigger of the gun is pulled, both the air and sand are forced out as a single entity.

Sand-blasting standards SA.1 : Light Blast Cleaning – When viewed without magnification the surface shall be free from visible oil, grease, dirt and poorly adhering mill scale, rust paint coating and foreign matter. SA.2 : Thorough Blast Cleaning - When viewed without magnification the surface shall be free from visible oil, grease, dirt and from most of the scale, rust, paint, coatings and foreign matter. Any residual contamination shall be firmly adhering SA.2.5 : Very Thorough Blast Cleaning - When viewed without magnification the surface shall be free from visible oil, grease, dirt and from mill scale, rust, paint, coatings and foreign matter. Any remaining traces of contamination shall only be as slight stains in the form of sport or stripes. SA.3 : Blast Cleaning to Visually clean steel- When viewed without magnification the surface shall be free from visible oil, grease, dirt and shall be free from mill of the scale, rust, paint, coatings and foreign matter. It shall have a uniform metallic color.

Painting There are two types of painting methods. That is Air painting & Air-less painting. Soon after the sand-blasting is over, sand-blasted surface should be painted with specific paints & tools to avoid corrosion. Air-less painting Air painting

Varieties of paints Painting Air-Less painting method is used for ships. In all the other occasions Air painting method is used. Kunsai Jotun Sigma International Hemple Chakugu K.C.C

How does air less painting machine works Piston Pump Located in the gun's spray head, the pump gets hydraulic power from the motor. The piston first moves up, creating a vacuum and therefore drawing paint up into the chamber. Then, as the piston moves forcefully downward, it shoves the paint through the hose and out of the narrow nozzle. It is this motion that results in such high pressure that the paint is atomized. Diaphragm Pump These pumps use pistons but do so slightly differently. The motor allows the piston to move up and down, but in this case, as it pumps, it quickly expands and contracts the flexible diaphragm. The piston's upward movement creates a vacuum, drawing the paint into the pump through the inlet valve. Its powerful downward motion then compresses the diaphragm, pushing the atomized paint out through the tip and onto the surface. Airless paint sprayers all have a hose, gun, tip and pump. The hose has a wider end, which goes into the paint, and a narrower end, which connects to the nozzle. The "gun" is what allows the painter to control the flow of paint. When the trigger is pressed, a valve opens to allow paint to flow through the tip and onto the surface. Varying tip sizes and shapes control the amount of paint that comes out. There are two types of pump: piston and diaphragm.
