Double-sided AR coating glass

Transparent Double-sided anti-reflective coating

Characteristics of tempered glass:
1. Tempered glass is a deep-processed glass product obtained by heating the glass to a temperature close to the glass softening point (600-650°C) and then rapidly cooling it or chemically tempering it. It has good mechanical properties and thermal shock resistance, also known as tempered glass.
2. The treated surface of the glass produces uniform compressive stress. Its strength is 3-10 times that of glass that has been well annealed, and its impact resistance is also greatly improved. When tempered glass is broken, network cracks will appear or small particles will be produced, which will not hurt people, so it is also called safety glass.
3. The thermal shock resistance of tempered glass is very good, the highest safe working temperature is 287.78℃, and it can withstand a temperature difference of 204.44℃. Therefore, it can be used to manufacture observation windows on high-temperature furnace doors, radiant gas heaters and dryers, etc.
4. Because tempered glass has good performance, it has been widely used in the automotive industry, construction engineering and other industries. It is commonly used as doors, windows, curtain walls, shielding and shop windows of high-rise buildings, portholes of warships and ships, and table glass. Tempered glass is now used in many electronic and electrical products.

The role of safety glass:
1. Safety: If the glass is broken, the fragments will resemble honeycomb-shaped obtuse-angled particles and will not cause human harm.
2. High strength: For the same thickness of tempered glass, the impact strength is 3 to 6 times that of ordinary glass, and the bending strength is also 3 to 6 times that of ordinary glass.
3. Thermal stability: Tempered glass has strong thermal stability. It can withstand a temperature difference 3 times that of ordinary glass and can withstand a temperature change of 200°C.
4. Improved safety: After tempered glass is damaged by strong force, tiny obtuse-angled particles will quickly appear, thus ensuring personal safety to the maximum extent.

 

Ultra-white glass
Ultra-white glass has fewer impurities, lower iron content, is more transparent, and looks whiter. Ordinary glass is somewhat green due to iron impurities. Ordinary glass and ultra-white can also be distinguished from the front. After all, ultra-white has a much higher transparency, and the thicker it is, the more obvious it is.

Compared with ordinary glass, ultra-white glass is much more expensive because its cost is more expensive and it has not yet become popular in China.

Ultra-white glass, also known as colorless glass, high-transparency glass, and low-iron glass, is the highest-end variety of glass products. It has high light transmittance and high transparency. The product is crystal clear, noble and elegant, and is known as the “Crystal Prince” of the glass family. known as. The light transmittance determines the quality of the glass. The light transmittance of float glass is 86%, while the light transmittance of ultra-white glass can reach more than 92%.

 

silk screen glass
In modern society, people need to use a large number of glass products in their daily lives, and it is no longer possible to get rid of glass. Glass is stable in nature, resistant to strong acids and alkalis, and is hard and durable. It is one of the raw materials required for most important equipment.

1. Ink: Ink is necessary for silk screen printing. Without ink, where would the pattern come from? There are many colors of ink, and adjusting ink is something that screen printing masters must learn.

2. Screen: The screen is prepared for printing patterns on glass. The stencil is first coated with photosensitive adhesive, and then combined with film and strong light, the pattern is applied to the stencil. Put the film under the screen, then expose the photosensitive adhesive on the screen with strong light, and then rinse off the photosensitive adhesive on the part blocked by the film, and the pattern is made.

3. Oven: The oven reminds us of baking. Yes, it is to put the glass in the oven to bake. After the glass is printed with a pattern, the ink on it is not dried quickly. If you take the glass at this time, you will touch it. Ink, this will destroy the pattern. After passing through the oven, the ink will dry and the pattern will not be easily erased.

4. Tempering furnace: Why do you need to go through the tempering furnace? Silk screen printing is divided into high temperature screen printing ink and low temperature screen printing ink. High temperature screen printing ink must be screen printed first and then go through the tempering furnace. In this way, the ink blends with the glass surface, and it is impossible to wipe the ink off.
