Abrasive blasting is a cleaning technique that makes use of abrasive material. Abrasives used vary a lot in their properties, with some being chemicals. Despite the physical and chemical composition of abrasives, they all work through physical effect. They have to come in contact with the surface being cleaned in order for them to produce a cleaning effect. When in need of Abrasive Blasting Los Angeles CA should be visited.
Abrasives can be placed in many categories based on various criteria. In one criterion, they are classified depending on whether they are natural or synthetic. Examples of natural abrasives are olivine and calcite. On the other hand, synthetic abrasives are manufactured. Most manufactured abrasives are usually by-products of other processes. For instance, calcium silicate is a by-product of steelmaking. Calcium silicate may also be a product of recycled bottle glass.
Finding products which are solely manufactured to serve as abrasives is also possible. As much as these types of abrasives are in existence, they are rear to find considering their small number. The associated extensive amount of work involved in production of abrasives explains their existence in small numbers. Not to mention the load work involved in refinery of abrasives.
As manufactured abrasives intended for cleaning are difficult to come by, most companies resort to recycling the ones in their possession. There are several ways of doing the recycling including centrifuge and magnetic recovery. The type of abrasive material in question usually determines the recycling and recovery procedure to be used. Other factors that determine the same include frequency of use and whether the material is used dry or wet.
The recovery or recycling of abrasives is harder to achieve in masonry applications. The main reason for this is that abrasives are utilized together with water or other liquid medium. Similarly, the abrasives used tend to be quite soft. The softness of the abrasives makes them to break down easily when they come in contact with the surface. That makes it harder to recover and recycle. Thus, only disposal can be done on such abrasives after they are recovered.
Classification of abrasives can also be done based on many other criteria. For instance, they can be classified based on their shape, density, hardness, solubility, absorbency, temperature, and size. Traditionally, particle size distribution has often been done using laboratory sieves, but that has changed to the use of laser diffraction due to technological advancement. Good abrasives have a narrow range of particle sizes.
If the piece of work being done is very sensitive, the abrasive used should have a smaller particle size. If all other factors are kept constant, sensitive work should be done using abrasives that have a diameter range of between 10 and 100 microns. On the other hand, if the work needs to be done on a bigger area, the particle size range should be within 80 and 250 microns.
Some abrasives have particles that are more than 250 microns in size. Such abrasives are best for use on surface preparation operations and industrial applications. Surface preparation is a very important process in many processes such as metalizing and powder coating. It improves adhesion between particles and surfaces.
