If you plan to renovate your house, to prepare a component for a new paint coating or cleaning rust and corrosion from tools, this sandblaster is the ideal abrasive solution .
Sandblaster is an air tool designed for the propulsion of compressed quartz sand or other granular grinding material to the surface of various items. This happens with great speed for grinding the surface for smooth finish or to remove dirt, rust and other contaminants, which over time has formed on surfaces. Depending on the design and operation of the sandblasting machine consists of a pneumatic gun, working under pressure, connected hose and air compressor , and some sort of tank or container from which pulls out a gun abrasive. The barrel of a gun, usually made of ceramic with a liner to prevent erosion of the abrasive for extended usage.
The three main types of sandblasting devices include models work under the influence of gravity , siphon and pressure . Sandblaster operates under the action of gravity consists of a hand gun, working under pressure, connected to an air compressor or tanks of compressed air with a hose. As a rule, are equipped with a tank of abrasive material mounted directly over the gun. When the trigger gun is pressed and is pressed continuously, the compressed air rapidly passes through the nozzle of the gun. At the same time opens a gap at the top of the gun, into which is inserted a funnel to provide both high air speed and gravity, dragging the sand from the hopper to the gun, and the muzzle of the gun.
A sandblaster siphon is equipped with two separately designed hoses, one is connected with the bottom of the handle of the gun, and the second is attached directly to the bottom of the barrel of the gun. When you press the trigger the compressed air creates the choke , pulling the material of abrasive down the barrel of a gun, where wystrzeliwany. In contrast to the models by gravity, the tank blastera siphon is located below the nozzle of the gun, hence the use of suction for removing grinding material.
Less common in domestic applications and operating similarly to that of tin in the aerosol , sandblaster high pressure includes a large closed container and quartz sand under high pressure. His gun was connected to the port at the top of the canister using a special hose. After pressing the shutter button, as compressed air, like sand, they passed through the hose and gun. Although this minimizes cleaning time to a professional crew, not sand you can collect and use again. In addition, the pressure vessel pitcher must be replaced when it is empty, making it less cost-effective solution for DIY.
Maintaining control, convenience and versatility
Type sand spreader, in which you are investing depends on your location and requirements of the workplace, so it is important to choose wisely. For example, if you expect a sandblasting of the surface in tight spaces and hard to reach places around the house, a good solution would be sandblaster siphon. Above the gun is not bulky container, which will prevent you to work. Take also into account the length of the hose for the pitcher to make sure that you have enough space to keep a container of 10 or more feet from the place of work when you happen to sandblast the same angles and narrow places.
Think about what type of compressor you choose and in combination with the device. Although there is no need to invest in a industrial unit with a large tank paper for projects, in a small house, the awareness of the power of the air blastrze it is important to provide sufficient force and pressure to maximize results quickly, while minimizing the need for unnecessary time cleaning. The ideal pressure range for manual feed gravity is from 90 to 120 pounds per square inch.
If you work in different places with different materials, use the sandblaster with integrated control valve the media , because you will be able to regulate the flow of its streams śrutowniczych depending on the situation. It is also important to be aware of the universality of tool for making a variety of abrasive materials, regardless of the type of the model. A sand-blasting apparatus can adopt silicon carbide , crushed glass and walnut shells, among other things, media.
Safety is also of great importance when working with potentially harmful contaminants transmitted through the air. If the constant use of sandblasting is part of Your trading, minimize risk of unhealthy exposure to blast through the room, protective clothing and other equipment such as a respirator .
A brief history of piaskarzy
Seeing the effects of the blowing winds of sand and corrosion, as Windows and rocks during military service, soldier and inventor, Benjamin Chew Tilghman used this knowledge as his inspiration for the invention and obtaining a patent first sand in 1870. Tilghman used quartz sand, as its pungent root for the machine with the flow of steam, air and water. It was the early phase of testing new technologies.
In 1904, Thomas Pangborn even more engaged in the invention Tilghmana by introducing compressed air by means of metal cleaning. This helped to create the basis for Pangborn Corporation , which today manufactures and supplies sand around the world.
New types of soybean blastycznych defined in the late 30-ies. XX. In response to growing concerns about the impact on high risk dust garden and potentially fatal krzemicy . Since then has been improved, versatility, safety and durability of the sand spreader to fit for different types of work, for both home and professional.
