Does frosted glass also have a process distinction

Frosted glass is a glass that has been rendered opaque through a process that roughens or obscures the clear surface of the glass Due to the rough surface of the frosted glass, the light is diffusely reflected, and the light is transparent without perspective. It can make the indoor light soft and not dazzling. It is often used for window glass in places such as bathrooms that need to be concealed and can also be used for glass ceilings, which have dual functions of privacy and decoration.

The production methods of frosted glass include mechanical sandblasting, manual grinding or hydrofluoric acid dissolution. The common frosted glass process, frosting, and sandblasting, is to blur the surface of the glass so that the light can be scattered evenly after passing through the lampshade. It is difficult for ordinary users to distinguish these two production processes, which can be identified by the following methods.

frosted process: Frosting refers to soaking the glass in the prepared acidic liquid (or coating acid-containing paste), corroding the glass surface with strong acid, and at the same time, the ammonia hydrogen fluoride in the strong acid solution causes the glass surface to form crystals. Therefore, if the frosting process is done well, the surface of the frosted glass is extremely smooth, and the scattering of crystals produces a hazy effect.  If the surface is relatively rough, the acid has serious erosion on the glass, which is a manifestation of the immature craftsmanship of the frosting master. Or some parts still have no crystals (commonly known as not ground to sand, or the glass has mottled), which also belongs to the master’s poor control of the craftsmanship. This process is technically difficult. The best feature of the process is the appearance of sparkling crystals on the glass surface, which are formed under critical conditions, mainly because the ammonium bifluoride has reached the point where it is running out.

 

Sandblasting process: This process is very common. It hits the surface of the glass with the sand particles shot at high speed by the spray gun, so that the glass forms a fine concave and convex surface, so as to achieve the effect of scattering light, making the light appear hazy when passing through. The surface of sandblasted glass products is relatively rough. Because the glass surface is broken, it looks like white glass in the original clear glass. This method is moderately difficult to manufacture

Actually, the two processes are completely different processes. Frosted glass is more expensive than sandblasted glass, and the effect mainly depends on user needs. Some special glass is also not suitable for frosted. From the point of the pursuit of nobility, frosted should be used. The sandblasting process can be completed in general factories, but it is not easy to do the sandblasting process well.

Usually, we are familiar with glass brick, tempered glass, frosted glass,
Insulating glass, laminated glass, shaped glass, etc.
In fact, there is not much difference in essence
Tempered, frosted, clipped, etc.
It is a different treatment method for the secondary processing of glass
thus showing different performance and visual effects
However, ultra-clear glass is fundamentally different from ordinary glass.
“Visual effects”
Generally, glass contains a certain amount of iron, which will lead to different degrees of green
The visual effect, the iron content in ultra-clear glass is the percentage of ordinary glass
Ten or less, with appearance properties similar to colorless crystals.
“Optical Performance”
1. Generally, the transmittance of ordinary glass is about 80%, and the transmittance of ultra-white glass is about 80%.
The light rate is above 91.5%.
2. Compared with ordinary glass, ultra-white glass absorbs more ultraviolet wavelengths
low, which can effectively reduce the transmission of ultraviolet rays, and at the same time of high light transmittance,
Reduce UV damage.
3. High light transmittance also reduces light refraction and reflection, reducing light pollution
At the same time as dyeing, it will not be produced through the objects between the inside and outside of the ultra-clear glass.
Produces chromatic aberration and distortion for added realism.

What is Ultra Clear Glass?

4. Special anti-reflection treatment on single or double sides of the ultra-white glass.
After that, the reflectivity can be reduced to around 1% and the transmittance can be increased again.
Up to 98%, the visual effect is almost transparent.
“Physical Properties”
Ultra-clear glass generally contains fewer impurities than ordinary glass.
The composition is more uniform and the physical properties are more stable than ordinary glass
Of course. The self-explosion rate of ultra-white glass after tempering is about 1/10,000
Compared with three-thousandths of tempered glass, it is much lower than tempered glass, which greatly improves safety.
gender”price” Ultra-clear glass has high technical content and is difficult to control in production.
Stronger profitability than ordinary glass. Higher quality determines its
Expensive, the price of ultra-white glass is about 5 times that of ordinary glass,
The cost is about twice that of ordinary glass, but the technical barriers are relatively high.
Has high added value.
