Tempered Heat Socked Glass

Overview of Heat Soaked Glass:

Tempering process increases the strength of glass many folds, offering a greater resistance to breakage. However, the raw-materials used in the manufacturing of tempered glass are not free from certain defects like nickel-rich contaminants such as stainless steel might be present, and then combine with sulphur to form nickel sulphide inclusions, which put tempered glass at potential risk of spontaneous breakage.

 

Spontaneous breakage due to NiS inclusions:

When glass is heat-treated, the nickel sulfide inclusions are modified into a form that grows or transforms with time and temperature. Once glass is installed and the nickel sulfide inclusions are solar heated, small cracks may develop from the inclusion. If these cracks penetrate the tension layer of fully tempered glass, the resulting release of energy will cause the glass to spontaneously break.

 

NiS inclusions change their structure and volume during the heating process of tempering. This changed state is ^trapped^ during the quenching process. So at room temperature, the NiS inclusions tend to change back to their original state, which having bigger volume, cause spontaneous breakage. This changing back of state could happen in a few minutes to a few years, making it unpredictable when the tempered glass may break. To minimize the risk of NiS breakages, a heat soak test is performed.

 

Heat Soak Process:

Effective Heat soaked test has been proposed and applied for tempered glass to avoid spontaneous failure in buildings, and the probability of spontaneous breakage was decreased. However, it was considered that a sufficiently low breakage risk was remained because of small NiS inclusion and small residual stress.

 

Heat soaking of tempering glass has carried out in respect to the draft of European Standard EN 14179. Following the tempering process, glass is heated to a temperature of about 290C for a minimum of 2 hours of the heat soak period, and then cooled slowly. This process allows the inclusions to revert to their original form and thus regain their stability. The advantage in using this process is that the heat-soak test removes over 95% of the problem without affecting the properties of the glass. The idea behind heat soaking is to allow the glass to break in the factory before installation to minimize the risks of accidents and injury. The amount and size of these inclusions vary from glass to glass. In all probability, the glasses that have NiS inclusions will break during this heat soaking process.

 

Applications of Heat Soaked Glass:

The use of heat soaked tempered glass is recommended where the risk of spontaneous breakage would cause difficulty, either from a replacement point of view, or where falling glass fragments may be unsuitable, such as roof or high level glazing, balustrades, screens and high level curtain walling.

Heat soak glass is appropriate where there is a risk of human impact. If breakage does occur, the breakage pattern is such that the resultant pieces of glass are relatively harmless and are unlikely to cause severe injury.

About the Plastic Frame:

Check below picture, the switchable transparent glass comes with plastic frame when you get the glass. So,

(1) Please consider the thickness of the frame before you tell us your customized size, plastic frame thickness: 2mm.

(2) Of course if you need a glass next to another glass, the connected side is no need frame, please tell us you need full sides come with plastic or some sides do not need.

About the glue:

If you just need 1piece switchable transparent glass, then you just need the our glue for the four sides, but if you need 2 or more glass installed together or you want to install it next to another common glass, it needs glue specially used in the middle of two glass.

Attention, the switchable transparent glass is very sensitive, the glue we supply to you is tested without problem, please don’t use other glue to install the switchable transparent glass, no matter surrounding size or the connected size between two glass.

What is Float Glass?

Float Glass is a kind of transparent flat glass is shaped by annealing, cooling, hardening,, cutting glass panels with even thickness. These are formed on metal fluid from molten glass which is produced in a melting furnace at a high temperature with high-quality quartzite sandstone powder, soda ash and dolomite as raw materials. The glass liquor floats on the metal tin liquor, so it is called Float Glass.

What can do the Float Glass?

Float Glass has high plasticity to processing like tempering, hot-curving, laminated, insulating, and coated glass. We have owned the advanced equipment ready for your deep processing products.

Safety Glass

Safety glass is glass with additional safety features that make it less likely to break, or less likely to pose a threat when broken. Common designs include toughened glass (also known as tempered glass), laminated glass, wire mesh glass (also known as wired glass) and engraved glass.

safety glass 1

safety glass 2

Tempered glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering, by design, creates balanced internal stresses which causes the glass sheet, when broken, to crumble into small granular chunks of similar size and shape instead of splintering into random, jagged shards. The granular chunks are less likely to cause injury.
