What is a Sandblast?
Sandblasting is a process in which abrasive materials are used to clean, prepare surfaces, remove rust, paint and other contaminants from metal and non-metal surfaces. This process is done by using air or water pressure so that the abrasive material hits the surface and cleans it. Shot blasting is also a process similar to sandblasting with some differences.
Sandblast Services in Tehran
The sandblasting process is often known as sandblasting. Sandblasting is just one method of this process, which is used for cleaning, polishing and reshaping the surfaces of hard surfaces. The device used to do this is called a sandblaster.
This process was invented by a person named Benjamin Cho Tilghman. Around 1870, Tilghman noticed that the surface of the glass becomes cloudy due to the impact of sand particles on the surface of the glass. Inspired by this phenomenon, Tilghman invented the first sandblaster. After inventing this device, Tilghman noticed the use of this device in operations such as sharpening tools, repairing, engraving and creating beautiful shapes on wood.
What is the use of sandblasting?
Sandblasting in Tehran has many different applications in different industries. Among the most common uses of sandblasting are layering, cleaning, smoothing and polishing the surface, making decorative surfaces, preparing for coating, removing mold, engraving and removing oil from the surface of the streets. In the following, we will explain each of these cases.
peeling
Peeling of surfaces before painting and coating can be introduced as the main application of sandblasting in Tehran. In many cases, it is difficult to remove paint marks, corroded sections, and other excess surface material using conventional methods. Using suitable sandblasting devices can easily remove excess materials from the surface of cars, buildings, machinery and other surfaces.
Cleaning
Sandblasting in Tehran is one of the methods of cleaning large surfaces such as industrial machines and buildings. This process is also used for cleaning small equipment. For example, the surface of rusty screws and wrenches can be quickly cleaned by sandblasting. Sandblasting can also be used to remove blockages in machinery. This ensures the proper functioning of the device and prevents its damage and depreciation.
Level preparation for coating
After layering and cleaning by sandblasting, the surface will be ready for painting, gluing or other coating activities. Non-standard surface preparation leads to incorrect performance of the coating. In addition, minimal cleaning (remaining dirt on the surface) also reduces the useful life of the coating. By properly preparing the surface, this method avoids the waste of costs due to the restoration of the coating (due to the use of inefficient methods or their incorrect implementation). Note that for weak surfaces such as wood, sandblasting should be done using materials such as walnut skin or glass beads so as not to damage the wood surface.
Straightening and Paying Level
In addition to cleaning, sandblasting creates a smooth and polished surface. In some cases, the presence of protrusions on the surface of mechanical parts prevents them from being properly connected to each other. In these cases, the use of sandblasting will smooth the surface and remove protrusions, stickers and other excess material so that the parts can be joined well. In addition, sandblasting provides the possibility of applying a matte or rough finish to different surfaces.
decorative surfaces
Another interesting use of sandblasting is to create artistic and attractive designs. Professional artists use this method to engrave unique patterns on the surface of wood, metal, glass and other materials.
Restore the original appearance to brick and stone
Brick, stone and concrete are widely used materials in the construction of residential and commercial buildings. The surface of these materials usually gets dirty over time. This problem destroys the beauty of the facade of the building. Despite other methods such as painting, using sandblasting is a good option for removing the damaged surface of concrete, paint or other additional layers. In addition to restoring the original appearance of the building, sandblasting also increases its lifespan.
Eliminate Home's Mold
Mold is one of the common problems in residential buildings that endangers people's health. Eye irritation, coughing, sneezing, asthma attacks and severe allergic reactions are some of the possible problems caused by mold. Removing house mold is one of the new applications of sandblasting. In order to remove house mold by sandblasting, baking soda (soda blast) or dry ice (ice blast) is used as an abrasive. One of the advantages of this method is easy access to roofs and low areas for cleaning. In addition, sandblasting allows effective removal of mold with minimal damage to the surface.
Wipe Oil Stain
Usually, over time, oil and grease stains accumulate on the road surface. One of the efficient methods to remove these stains is wet sandblasting or wet blasting. In this method, the combination of hot water, soap, and intermediate material are applied to the surface at the same time. During the wash, the water and the cleaner break the bond between the stains and the abrasive removes them from the surface.
Types of Sandblasting Device
Dry sandblasting
In dry sandblasting, abrasive materials are sprayed only with air pressure and no liquid additives are added to the materials. One of the advantages of using this sandblasting method is the possibility of recycling abrasive materials and reusing them. The water is mixed and spraying is carried out by means of wheel blast systems. This method is usually used to prepare surfaces with large and non-portable dimensions. Note that in wet blasting, it is tried to prevent abrasive materials from hitting the surface and damaging it as much as possible.
