Laser Cleaning

How It Works

Laser cleaning takes off unwanted layers from surfaces very carefully. It uses strong laser beams that hit the surface and break the bond between the dirt and the material below. The laser makes things like rust, paint, or dirt melt, turn into gas, or break into tiny bits. You do not have to touch the surface, so it does not get scratched or damaged.

The laser sends quick, powerful bursts to the spot you want to clean. These bursts can shake, melt, or turn the dirt into gas. Sometimes, the laser makes a small shock wave that helps lift the dirt away. You can change the laser’s power and speed to fit the material and how thick the layer is. This way of cleaning is very tidy and does not use chemicals or make much dust.

There are a few ways to use laser cleaning:

• Dry cleaning is good for taking off rust or paint from metal.
• Wet cleaning uses a liquid to help clean soft things, like old statues.
• Inert gas-assisted cleaning keeps new dirt from sticking, which is important in aerospace.
• Some ways mix lasers with safe chemicals for special cleaning jobs.

Main Applications

Laser cleaning is used in many jobs because it is safe, quick, and gentle on surfaces. Here are some ways people use it:

1. You can take off rust and oxides from metal parts in factories and repair shops.

2. You can remove paint, coatings, or grease from car parts, engines, and tools.

3. You can clean molds in rubber and plastic factories to keep products good.

4. You can get surfaces ready for welding or clean up after welding by taking off burn marks and leftovers.

5. You can keep pipelines working by taking off rust and grease, which helps stop leaks.

6. You can fix up old buildings, statues, or art without hurting the real material.

7. You can clean sensitive electronics, like circuit boards, by taking off dust and old solder.

Tip: Laser cleaning is great when you need a careful, earth-friendly, and no-touch way to clean, especially when compared to rough methods like sandblasting.

Sandblasting

How It Works

Sandblasting cleans surfaces by shooting small rough pieces very fast. It uses strong air or a vacuum to push the abrasive through a nozzle. When these pieces hit the surface, they knock off rust, paint, or dirt. There are different systems like pressure pot, siphon feed, and direct pressure. Each system changes how the abrasive moves and how fast it goes.

You can change the blasting pressure, the kind of abrasive, and the nozzle angle. These choices change how well you clean and the look you get. If you use more pressure or rougher abrasive, you can remove hard coatings faster. Wet sandblasting mixes water with the abrasive. This helps lower dust and makes the finish smoother.

Note: Sandblasting is good for big areas and tough jobs. You can use it on metal, concrete, and wood.

Main Applications

Sandblasting is used in many jobs because it is quick and works well for big cleaning. Here are some ways people use it:

• You can clean metal, take off old paint, and get concrete ready for coating.
• In car work, sandblasting removes paint, rust, and cleans engine parts.
• Shipyards use sandblasting to clean ship hulls and do repairs.
• Oil and gas workers use it to clean and fix pipelines.
• Metal shops use sandblasting to get parts ready for painting or coating.
• Builders use it on concrete and metal, especially in big projects.
• Aerospace companies use careful sandblasting to meet safety rules for plane parts.
• Artists and builders use sandblasting to make designs on metal, signs, and sculptures.

Sandblasting also helps fix old buildings, clean train cars, and get surfaces ready for coatings. Many companies now use machines for sandblasting to work faster and better, especially in shipyards and big factories.

Sandblasting is a strong way to clean, fix, and get surfaces ready, especially when you need to do big areas fast and well.
