Grinding surfaces to a high-quality finish are often achieved through grit blasting.
Though this process can be used for all types of metal, it is most commonly associated with steel. To help you get the best results from your grit blast job, we’ve compiled 10 tips that will make sure you’re doing everything right.
1. Grit blasting is a process that can be used to grind the surface of the steel, and it’s most commonly associated with this type of metal. Grit blasting is used to clean surfaces by blasting them with abrasive particles. These abrasive particles can remove rust, paint, and debris by grinding them away. Grit blasting prevents steel grinding or welding. It can also help extend the lifespan of steel materials.
2. The grit in the blast material acts as an abrasive agent. It can be mixed with other materials to form a flame retardant, a sealant, or a sealant and flame retardant in one.
In addition to the grit, it can also be mixed with a polymer and formed into any shape. The plastic-type of blast media provides strength and is easily formed, so it is ideal for applications such as lining storage tanks or rail cars and making concrete cladding panels. It can also be used for shotcreting fireproofing and tank linings.
3. When grit blasting, you want to make sure you use enough water so that your blast media sticks together. Otherwise, you’ll get water droplets that are too hard to target and will end up splashing all over your parts.
4. You also need to keep your nozzle at a distance from the surface being blasted so that your blast is going to hit the target surface at the correct angle.
5. If you’re hoping for a smooth finish on your project after blasting, make sure not to over-sand or grind afterwards. Too much sanding or grinding will ruin the finish.
6. It’s important not to let any dirt or other contaminants into the area where you are working because they will interfere with how well your blast media works.
If you are dealing with large amounts of dirt or contamination, it may be necessary to use a soup to help dislodge the contaminants. Blasting aids are often used for this purpose. A blast aid is similar to dishwashing soap but much more forceful.
7. If you want to achieve a glossy finish on your project, make sure that you are keeping the nozzle tip at the right distance above the surface being blasted. Otherwise, you risk not smoothing the surface as thoroughly as you should.
8. After blasting, you should always rinse your blasted material with clean water to remove any remaining particles. Since the media are basically sand, you want to make sure that the water you use is clean.
9. Unless your requirements specifically call for using dry abrasives, it’s best to use wet blast media when blasting steel surfaces.
10. Make sure you keep an eye on the humidity levels in the area where you are working because this can affect how well your grit blast material works.
Conclusion
The grit blasting process can be used to grind the surface of the steel, and it’s most commonly associated with this type of metal.
When you’re using a grit blast media, make sure that you use enough water so that your blast media sticks together. If you want to get a smooth finish after blasting, don’t over-sand or grind afterwards.
It’s important not to let any dirt or other contaminants into the area where you are working because these will affect the quality of your work in an undesirable way!
