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.
It is usually difficult to recycle or recover abrasives in masonry applications. The reason behind this is because abrasives are utilized in wet form. In addition, abrasives used in this situation usually tend to be quite soft. This means that with each subsequent use they break down further. As such, recovering them from the site for recycling purposes is impossible. Normally, they only recovered for disposal once the job is finished.
Many criteria can be used for the classification of abrasives. Some of these factors include solubility, absorbency, shape, density, size, hardness, and temperature. Traditionally laboratory sieves have been used for particle size distribution. However, that has changed as a result of better technology being invented. Today, particle size distribution is done using laser diffraction. Any abrasive that is considered good should have a narrow particle size.
Abrasives of smaller particle sizes are preferred for sensitive tasks and surfaces. Such surfaces require abrasives that have diameters that range between 10 and 100 microns in size that is if all the other factors are kept constant. However, large scale applications need bigger particle sizes. The particles should range between 80 and 250 microns in the size of the diameter.
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.
