Q.31 What should we know before buying a shot blasting machine?   

Points to remember while buying shot blasting:

  • 1. Purpose or the end use of the machines to be clearly communicated to machine manufacturer to enable him provide you the best fit for your intended
  • 2. Type of Shot Blasting Machine because each type of machine have different approach to surface preparation.
  • 3. Machine should be chosen on the basis of type and thickness of material that are you trying to remove.
  • 4. Depends on production rate that you need to achieve.
  • 5. Quality of inner fender of shot blasting machine is of prime importance as it helps to determine life of shot blasting machine.
  • 6. Other factors like cleaning efficiency, area, and dust protection are also valuable inputs while choosing shot blasting machine.
  • 7. Machine selection based on type of power (electricity, compressed air etc.) that you used which is best suited for your needs and job conditions.
  • 8. Most important budget: you can justify the cost of purchasing your own machine if you do lot of surface preparation work otherwise sub contracting the work makes sense.

Q.32 What is meant by Sweep Blasting?   

To protect metal surface, a thick coating of zinc is covered on steel or iron to prevent it from rusting because the zinc coating prevents corrosive substances from reaching the underlying surface. Zinc acts as a strong deterrent against rust and is a wonderful coating medium for nickel polish on plastic and metal. But it can develop oxide which deters effective galvanization and can loosen up paint particles from its surface.

For application of organic paint onto a surface before it is galvanized, the oxidized layer of zinc must be removed so that zinc surface can be coated successfully with a smooth finish and paint grip. This removal means treating with abrasive sweep blast cleaning for the preparation of a galvanized coating prior to the application of an organic coating.

Since the outer layer of pure zinc requires very little impact or scouring to get required surface roughness, the blasting process should lightly roughen the surface without removing a major amount of the galvanized coating. The purpose of this procedure is to remove the oxide film from the zinc surface. Light sweep blasting can provide maximum topcoat adhesion over galvanizing.

Q.33 What is concrete Shot Blasting?   

Concrete Shot Blasting is the process of resurfacing layer made of concrete to retreat its look like a new preparation. For lifelong concrete grounding, concrete overlays are best but they require a clean and solid base to grasp the surface permanently. For this homework, treating a concrete floor with shot blasting ensures that you have a perfect dirt free surface to overlay it.

Concrete Shot Blasting Removes all substances that could inhibit the bonding of the overlay due to dirt, oil and grease. Similarly, it chisels out any old coatings, sealers or paints applied to the surface area apart from filling minor cracks, spalling, scaling or delamination to a solid concrete form.

The abrader effectively roughens the profile to improve the "grip" of the overlay. Thus, cement shot blasting is an effective way to prepare concrete substrates for resurfacing.

Q.34 What is Shot Peening ? What is the Purpose of using this Process?   

Shot peening is a cold work process that effectively treats finish metal parts with small metallic shots by compression to prevent fatigue and stress corrosion failures. The process prolongs product life also. In shot peening, small spherical shots are shot at the surface of the part to be finished. The hammering action of the shots creates small dimple beneath the surface causing compression stresses under each dimple. As the media continues to strike the part, it forms multiple overlapping dimples throughout the metal surface being treated and the compression stress strengthens the metal to resist corrosion fatigue and cracking. It can include wheel blasting, ultrasounic peening and laser peening. Cut wire metal shots are also used as a medium.

Shot peening is done in the automotive industry on gear parts, gear wheels, springs, etc. and also in foundaries for sand removal, descaling and finishing of casting. Due to its compression strength, it is a crucial process in spring making.

Shot peening not only increases the product life of treated metals but improves wear characteristics, distortions and surface texturing too. Used in creating aerodynamic curvatures, the increased strength of treated parts allows for lighter-weight parts to resist higher wear and fatigue values.

Q.35 What is the process of shot blasting?   

Shotblasting uses small metallic shots intended to clean, strengthen or polish metal. It includes two technologies used: wheelblasting or airblasting.

Wheelblasting – This process directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. It is used for heavy equipments and large metal parts to be treated, derusted, or descaled.

Air Blasting – For smaller treatments, airblast machines are used in the form of blast cabinet which eject the blast media by compressed air through a nozzles onto the component. Wet blasting is also used for special applications with a media-water mix.

The media is pumped out using compression in the blasting cabinet and it forcefully strikes the surface intended to be treated. Upon impaction, the area is peened, polished or derusted.

Q.36 What do you mean by sand blasting?   

Sand blasting is an effective way to shape or smoothen a surface of any material using compressive force. When blast media is thrown out of a blasting machine from a nozzle using compressive force, it strikes the surface directed by friction to remove paint, rust, grease or just treat it for recoating. For peening or polishing also, different media can be used. While grit materials are used to blast a layer similar to that of a sandpaper, soft media like ground nut shells and corncobs are best for wooden applications and soft surfaces.

Q.37 Why Sandblasting is done?   

The main purpose of sand blasting is to remove paint or rust and other surface-pollutants from machinery, cars, houses and almost any other surface. Meanwhile, it is a surface treatment process widely used in a variety of different industries for various purposes.

Q.38 What is the use of Sand blasting?   

To Remove paint or rust from the surface Sand blasting is highly recommend. This process is forcibly propelling a stream of abrasive material against a surface under high pressure to smooth or rough the surface. Sand blasting can lead to the paint looking uneven when it cures and bubble once the project gets finished.

Q.39 What is a Sandblaster job?   

The sandblaster works to clean and abrade a surface, typically metal, of any rust, paint or other unwanted surface materials. In this technology, the hose connects to the air tank, and the hopper is filled with an abrasive to ensure best results without any obstacles.
