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.
Since manufactured abrasives that are meant purposely for the job of cleaning are hard to come by, companies usually opt to recycle the ones they have. Recycling is done through various methods such as magnetic recovery and centrifuge. The method of recovery and recycling usually depends on the type of abrasive material under consideration. Also, recovery of the materials depends on whether they are used wet or dry and the frequency of use.
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.
The categorization of abrasives may also be based upon several criteria. For example, most typical classifications are based on temperature, density, size, shape, absorbency, hardness, and solubility. Particle size distribution has traditionally been done by the use of laboratory sieves a trend which has since changed to laser diffraction as a result of advances in technology. Narrow particle sizes is a feature of all good abrasives.
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.
Lastly, abrasives with particle size exceeding 250 microns are suited for industrial uses. Besides this they are best for uses in procedures involving surface preparation. In preparation of surfaces, the abrasives help in removing all the external debris, hence creating a suitable texture that helps improve the adhesion.
