Shot
Blast Technique is widely used in metal-using industries such as construction,
automotive, aerospace, shipbuilding etc. Some of the shot blasting applications
include surface cleaning, rust removal, thermal scale removal, mold
degeneration, paint removal, surface quality improvement in dye, plating or
coating.
Shot
blasting machines are very useful for cleaning, strengthening or polishing the
metal. Therefore, it is very important to choose the best shot blasting machine manufacturers. Only if you have chosen a
high-quality machine, you can achieve the required results.
Shot
blast technique is an environmentally friendly way to prepare or refurbish large
parts of concrete surfaces. It is also a cost-effective way to reduce drying
time and provide a surface that is ready to apply coatings or overlays quickly.
This
technique is dust free that saves a lot of time and labor. Shot blasting has become a preferred method for coating
manufacturers as it helps to produce bonding properties that reduce the
possibility of coating failure. It is excellent for removing graffiti, milling,
rust, and scale from the surface of the metal.
Types
of shot blast method
The
most common abrasive used in this technique is sand, also called sandblasting.
Garnet, chilled iron, glass beads, and olivine are also blasting machines used
for blasting. Garnet and chilled iron, however, are extremely abrasive and
coarse and should not be used on a soft surface. Generally, glass beads and
olivine are used as polishing agents and can be used on sensitive surfaces such
as rubber, glass, and metals.
How
does shot blast technique work?
A
controlled stream of abrasive shot material is quickly thrown to the target
surface. A blast wheel is located in the center of the shot blasting machine,
which rotates at high speed and feeds the metal abrasive into the center. From
this point, it is accelerated and thrown in the direction of the surface to be
prepared. The abrasive as well as the contaminants rebound in a separation
system containing a dust collector that removes dust and contaminants that have
been pounded.
Shotblasting is more beneficial for surface preparation compares
to other conventional Method because harsh chemicals do not need to be used.
There is also a wide variety of abrasives to choose from. This process can be
done either outdoors or indoors. This method does not cause any form of dust
pollution. However, special care must be taken when performing this technique,
as dust in the air may cause difficulties in breathing workers. Metal dust can
also be harmful to health as toxic substances such as manganese, lead, and
cadmium and can be harmful if inhaled.
Hence
you should always remember to include trained staff to handle this process. Do
not forget to buy only a high-quality shotblasting machine and other industrial equipment.
