Description
Sandblasting is also known as abrasive blasting. Basically, it is the operation of forcibly propelling a stream of abrasive material against a surface. The sandblasting operation is done under high pressure to smooth a rough surface, roughen a smooth/Shape the surface to remove its contaminants. There are several variants of sandblasting process like bead blasting, Soda blasting and shot blasting. Before sandblasting, it is mandatory to know about its materials and the pros and cons. If your job profile is related to sandblasting or you owned a company that involved in the same process, you need to stay with us. In this article, we will discuss sand blasting machines materials and its pros and corns. But before it, let me also clear some of the details of its operation.
There are Two Types of Sandblasting Processes:
Water-Driven It is applied for reducing surface deterioration, most commonly water driven process is used for brick or concrete surfaces preparation.
Air-Driven This process is best suited for metal surfaces, to prevent moisture buildup and avoid water intrusion in the surface.
Sandblasting is the process of propelling abrasive by using the pressurized liquid or compressed gas as propellant. There are many generic terms for this process that is generally related to the sandblasting abrasive media used for this process. Here are the details of abrasive materials.
Olivine does not contain chloride, there will be no corrosion and adhesion problems. The iron (Fe2O4) in olivine is the most stable form of iron. Due to this feature, it does not react chemically with the oxygen in the air and water. Therefore, since there will be no oxidation, the paint process after cleaning will have a longer life. Olivine does not contain free silica. And because of this feature, it does not cause silicosis disease. It removes the health and safety concerns of the operators. Moreover, olivine is also used as a fertilizer in the treatment of drinking water and in agriculture. However, silica sand contains free silica in its varieties and creates a carcinogenic hazard for the users of this sand in terms of health. The use of minerals containing free silica is prohibited in various countries (such as Norway, Sweden, England and the Netherlands) on the grounds that they cause silicosis disease. In our country, the use of minerals containing free silica was banned by the Ministry of Health in 2009. It is environmentally friendly. It has no harmful effects on the environment. The grain shape of the olivine is angular and this feature significantly increases the surface cleaning speed. The hardness of olivine is 6.5 -7, which is an important feature for its use as an abrasive material and ensures high efficiency in surface cleaning.
