What is Semi-tempered Glass?

Semi-tempered glass, also known as heat strengthened glass, is a kind of glass between ordinary float glass and tempered glass. It has some advantages of tempered glass, having strength 2 times higher than regular float glass while avoiding the disadvantages of tempered glass, such as unsatisfactory flatness and easy to explode.

Semi-tempered glass is not considered as safety glass as it will result in larger fragments and cracks in radial pattern when it’s broken. Although most of fragment will be free of sharp edges, it could still cause injury. Therefore, semi-tempered glass is not suitable for sunroof or places with high possibility of being bumped into.

What is the structure and function of the tempering half-chiller valve on the flat glass tempering furnace?

The tempering half-chiller valve on the flat glass tempering furnace is a simplified butterfly valve composed of valve plate, rotary shaft, connecting rods, pin, cylinder, cylinder support frame, and other components.

Driven by the telescopic action of the cylinder, the valve plate of the tempering half-chiller valve on the flat glass tempering furnace completes the rotation to throttle down the round tube outlet of the air distribution box in order to regulate the size of the blowing area by the blowers, making it possible to process thinner glass with blowers of the same power.

How to adjust the glass flatness using air valve in the air distribution box of glass tempering furnace?

When the air valve in the air distribution box is in the middle position, the corresponding pointer indicates zero. The indicator reading points to positive values when the air valve moves up and points to negative values when it moves down.

If the tempered glass bends upwards, it means that the wind pressure on the upper part of the chiller in the tempering section is low. At this point, adjust the air valve downward or to the direction of negative value. To the contrary, when it bends downwards, adjust the air valve and move it to the direction of positive value.

How does the C+ ConeBend bending mechanism of LandGlass glass tempering furnace work?

Edge cracks usually appear on the single curvature bent glass processed in the traditional method. LandGlass C+ Conebend glass tempering furnace ,using special bending and quenching mechanism and driving system, can bend the glass once it comes out of the furnace and form the final shape longitudinally, successfully avoiding the edge cracks. For super-long bent glass, this technique can also effectively avoid the quality defects due to the temperature difference at two ends of the glass sheet because it is unnecessary to wait for the whole glass sheet coming out of the furnace.

Besides, LD-C+ Conebend glass tempering furnace has two independent transverse arch forming mechanisms, which can form arches with different radii at two ends and independently form the curve by its own settings. By this means, cone-shape glass can be produced successfully.

What is the the single chiller conventional tempering of LandGlass’ C+ flexible bending tempering furnace?

Single chiller conventional tempering: By using special variable curvature mechanism and drive device to gradually change the shapes at two ends of the chiller, the glass can start bending as soon as it leaves the oven and forms desired curvature along the length of the glass. In addition to producing gradually bending tempered glass, it can avoid cracking that often occurs when producing single curvature bent tempered glass using traditional approach and meet users’ processing requirement for high-quality bent tempered glass. This method is suitable for processing curved tempered glass with a length less than or equal to 6 meters.

0.1mm-Thin Flexible Glass For Folding Phones，Being Developed by Corning

Gorilla Glass-maker Corning is aiming to bring its expanse of knowledge to bear on the problem of foldable smartphone panels with a new type of flexible glass, according to a recent CNET report taking an inside look at the new material. Corning general manager John Bayne said that the challenge was creating a glass that’s thin enough to bend without sacrificing the resilience needed to protect a display.

Bayne notes that the company is targeting a “3- to 5-millimeter bend radii” for its 0.1mm thick glass, which could allow a foldable phone to be as thin as 6mm to 10mm with the folding screen wrapped around the outside.

”In a glass solution, you’re really challenging the laws of physics, in that to get a very tight bend radius you want to go thinner and thinner, but you also have to be able to survive a drop event and resist damage.” said Bayne. “The technical challenge is, can you keep those tight 3- to 5-millimeter bend radii and also increase the damage resistance of the glass. That’s the trajectory we’re on.”

AGC Achieve 5G Communication Using Glass Antenna

Recently, AGC announced that they have achieved what is believed to be the world’s first 5G mobile telecommunications using an antenna embedded in synthetic fused silica glass to transmit and receive 28 GHz 5G radio signals for stable, high-speed mobile communication in buildings, vehicles and trains.

The antenna embedded in synthetic fused silica glass was used to verify 28 GHz 5G mobile communication with downlink speeds averaging 1.3 Gbps within a 100-meter range. The verification tests, which used a vehicle fitted with multiple antennas and traveling about 30 km/h, were conducted in the Sumida area of Tokyo.

5G radio signals in the 28 GHz band are seriously weakened when they pass through car windows to the interior. In addition, radio waves from urban 5G base stations reach the vehicle from various directions. The new AGC glass antennas were therefore used in multiple positions on the test vehicle including the windshield, side windows and rear window. The tests confirmed that these antennas switch seamlessly as the car moves, enabling 5G data to be transmitted and received in ideal directions with maximum signal strength and stability.

In addition, these 5G glass antennas are very small and transparent, allowing them to be fitted discreetly, without spoiling the vehicle’s appearance or the passengers’ line of vision.
