For Good Abrasive Blasting Los Angeles CA Offers A Recommendable Destination

By Virginia Murphy


A cleaning process in which abrasives are used is known as abrasive blasting. Abrasives differ in properties and their chemical nature. Regardless of whether these products are by nature chemicals or not, they for sure achieve their cleaning effect by physical means. As such, their way of removing dirt is be making contact with the surface or substrate in question. When in search of Abrasive Blasting Los Angeles CA should be given priority.

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.

Some abrasives are also produced for the sole reason of being used for cleaning. Although they exist, it is hard to find such abrasives. They are not easy to find because there is too much work that is needed to produce the products. Also, too much work is needed in refining the abrasives.

Like stated earlier, abrasives that are designed specifically for cleaning are hard to find and even produce. That makes it reasonable to recycle the ones already in use. Magnetic recovery and centrifuging are the methods used for recovery. The method chosen to use in recovery and recycling is usually determined by the nature of abrasive in question. Whether the abrasives are used in wet or dry form also determines if they can be recovered or not.

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.

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.

In case the work piece in question is sensitive, then small-particle-sized abrasive has to be used. With all other factors kept constant, a sensitive work must be done with abrasive material of a precise diameter range of 10 to 100 microns. On the contrary, if the work requires to be done on a larger area, then the particle size range must be kept between 250 and 80 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.
