Difference Between Sandblasted Glass And Heat Strengthened Glass. In this article, you will come to know about what is sandblasted glass, what is heat strengthened glass, what is the main difference between sandblasted glass and heat strengthened glass, and much more.
Both the terms sandblasted glass and heat strengthened glass are the types of glasses that are used in construction and for different purposes. Glass is a transparent substance that can be transparent, translucent, or brittle. The process that is used to manufacture the glass is known as the ‘fusion process’. In this process, the sand is fused with soda, lime, and various admixtures. Then this mixture is cooled rapidly, thus forming a glass.
The difference in the glasses lies in their making process. Here, we will first discuss the main difference between sandblasted glass and heat strengthened glass, then differentiate between them in detail.
What Is The Main Difference Between Sandblasted Glass And Heat Strengthened Glass?
The main difference between sandblasted glass and heat strengthened glass is that the:
-Sandblasted glass is made by bombarding any glass surface with small hard granulated particles. Usually, sand pieces of walnut shell are streamed at the glass sheet to remove the clear sheen. This creates a frosted aesthetic and a cloudy appearance.
-Heat Strengthened glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi, which makes it stronger than annealed glass.
What Is Sandblasted Glass?
Sandblasted glass is made by bombarding any glass surface with small hard granulated particles. Usually, sand pieces of walnut shell are streamed at the glass sheet to remove the clear sheen. This creates a frosted aesthetic and a cloudy appearance. This process of glass making weakens the glass and makes the surface prone to staining.
If you want some of the areas of glass to be transparent choose sandblasting and if you want the whole glass to be obscured choose frosted glass. Like half shower screen can be transparent and have can be obscured. Any glass can be sandblasted from tinted glass, painted glass, laminated glass to even mirror.
What Is Heat Strengthened Glass?
Heat Strengthened Glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi for 6mm glass, which makes it stronger than annealed glass. It has more resistance to thermal loads and is stronger as compared to annealed glass.
This glass is also referred to as semi-tempered. That’s why it cannot be used as a safety glass. It cannot be cut, drilled, edge-ground, or sandblasted after the heat strengthening. Heat-strengthened glass is shattered like tempered glass, however, it got fractured into dangerous large shards.
Heat strengthened glass is used in laminated glass to give it extra strength, for example, overhead and sloped glazing.
What Are The Properties Of Glass?
The 6 main properties of glass are as under:
The main property of glass is transparency. The transparent the glass, the better the vision of that glass. Usually, the glasses are transparent from both sides, but there is some glass that is transparent from one side only. An example of such types of glasses are mirrors that have only one side transparency.
The strength of glass is the second property of glass. It depends on the modulus of the ruptured value of glass. The glass is very brittle initially. We add admixtures and laminates to make it more stronger.
The workability of the glass is a superior property. Glass can be moulded into any shape when melted.
A glass should have visible transmittance property. It means that a visible fraction of light should pass through the glass.
The u-value of the glass is the amount of heat that can be passed through the glass. Like, if the glass is insulated the glass will have a lower u-value.
A glass can always be recycled. It has 100% recyclable property. It is used as a raw material in the construction industry.
