How to Sandblast Sandblast, Sandblasting, Sodablast, Sodablasting. What is Sandblasting Sandblasting is the generic term for abrasive blasting. This terminology resulted because sand was the first abrasive material used in a blasting process over 1. This is ironic, in that the use of actual silica sand is never recommended due to its health hazards. Sandblasting or abrasive blasting also referred to as media blasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants and paintscoatings. Compressed air is typically used to propel the blasting material often called the media. There are several variants of the process, such as soda blasting, bead blasting, and shot blasting. To keep things simple, we will mostly refer to the generic terms sandblasting and sandblaster, although most of what follows applies all of the variants mentioned above. Also, please realize that the information given here is by no means a comprehensive guide to sandblasting. Think of it as an introduction to sandblasting for people who have never done it before, or who have an interest in finding out if sandblasting is right for doing their kind of work. Before we go much farther, it is very important to remember that your air compressor is the most important component of your entire sandblasting system. The production rate, efficiency and cost per square foot of sandblasting are highly influenced by the volume CFM and pressure PSI of compressed air maintained through the blast nozzle of your sandblaster.

There are two general types of sandblasters portable and cabinet. As the name suggests, a portable blaster can be moved around a work area, or taken to a remote location, if desired. A cabinet is a fixed, enclosed unit, which is placed in a fixed location like a workshop or garage. There are two general kinds of sandblasting cabinets cabinets siphon cabinets sometimes referred to as suction cabinets and direct pressure cabinets. In general, a siphon cabinet is less expensive to purchase than a direct pressure system and has lower maintenance costs. Production rates are not as high as with a direct pressure cabinet. If you are a typical hobbyist or a business, requiring occasional use, a siphon system will usually work out just fine for you. If you are a high volume production business or an individual requiring faster production rates you may want to consider a direct pressure system. Besplatne Knjige Pdf.

Whether you use a siphon or a direct pressure cabinet, you will need a dust collector, which attaches to the cabinet and removes airborne dust and debris from the cabinet, giving you clear visibility inside the cabinet. You cant get much work done if you cant see what you are doing There are also recycler style dust collectors available, which filter out debris and dust and recycle good media back into the cabinet. The first step in learning how to sandblastis to determine what type of work you want to do. Based on the answer to that question, you can determine what kind of equipment you need. For example, if you want to strip paint from a surface, which is too large to fit inside a sandblasting cabinet, you will need to use a portable sandblaster. If you want to sandblast parts and pieces inside your garage or workshop, you may want to use a sandblasting cabinet. If you are unsure of exactly what equipment would work best for your individual needs and budget, its best to get advice from an expert. One of the best is ACE Automotive Cleaning Equipment out of Michigan. They make high quality, affordable sandblasting equipment  of all kinds, and have years of experience in helping people with their sandblasting  and soda blasting needs. Blasting Material Abrasive Material Blasting Media. Once you have determined the general type of sandblasting equipment that is best for your needs, it is very important to determine the best type of blasting material  media blasting for the specific kind of work you want to do. You also need to determine the best grit size to use for your job. Do you want to clean up heavily rusted metal, or do you want to strip the finish from a wooden chair Do you want to remove bottom paint from a fiberglass boat without harming the gelcoat, or do you want to etch a design in a piece of granite or glass There are many different types of blasting materials, each with its own pros and cons depending on the type of work you want to do. Although sandblasting is one of the generic terms for abrasive blasting or media blasting, you should never actually use any type of silica sand to sandblast Silica sand can cause a type of lung disease called silicosis. Some of the most popular blasting materials are aluminum oxide, glass bead, silicon carbide, and baking soda sodium bicarbonate. Aluminum oxide would be a good choice for cleaning that heavily rusted metal, but you might very well blow a hole in that fiberglass boat bottom with it. Soda blastingwould be best for stripping the paint off of the fiberglass boat bottom, but would not remove that heavily pitted rust although a mixture of 8. Here is a general application guide for abrasive materials. It is for comparative purposes only Blasting material normally comes in different grit sizes. The higher the grit size is numerically, the finer the particle size. The lower the grit size, the coarser the particle size. Lower grit sizes are more aggressive, in general, than higher grit sizes of the same blasting material. For example, Aluminum Oxide 6. Aluminum Oxide 1. Its important to use the correct material in the correct grit size to properly do your work. Again, if you arent sure about what blasting material to use for your type of work, get a recommendation from an expert. It will save you a lot of time, frustration, and money versus trying to guess, if you are not sure. Air Compressors CFM PSIGetting back to air compressors, all sandblasting equipment must have the required air pressure, usually referred to as PSI pounds per square inch and the proper volume, usually referred to as CFM cubic feet per minute to operate properly. All air compressors are rated by these factors. In the specifications for an air compressor you will see these ratings expressed as x cfm at y psi. Make sure that your air compressor can generate at least the minimum required volume of air cfm that your sandblaster requires, and more than the minimum cfm is generally better. For example, if your sandblaster requires 1. Its alright if it generates more than 1. Keep in mind that the velocity of the abrasive material, as it leaves the blast nozzle, and the efficiency of the sandblasting process are going to be reduced by a little over 1 for every pound of pressure drop below the ideal blasting  pressure. So if you are trying to blast at 1. Also remember that the cfm output of your air compressor will determine the size of the nozzle you can use with your sandblaster. In other words, if you have enough cfm to maintain blasting pressure with a certain nozzle size, you may or may not have enough cfm to blast with the next bigger nozzle size, without experiencing a pressure drop. With respect to air pressure, most sandblasters have an adjustable pressure regulator, which is used to set the final blasting pressure.
