How To Distinguish Between Toughened Glass And Ordinary Glass

 The earliest appearance of ordinary glass in the history of glass was ordinary glass. For the appearance and invention of ordinary glass, people didn't think it was of any use at first. It was only used as a vessel and vase. Gradually, everyone discovered the advantages of glass, first as a window in the home. People find that glass can block the wind, and because the glass is transparent, it does not block the light. In the daytime, the inside of the house is as bright as the outside, and in winter, the outside cold wind cannot blow in. Therefore, many people use glass as windows. . Later, everyone discovered that glass can also be made into a lot of handicrafts, which are both simple and beautiful. Gradually, the multi-faceted effects of glass have been discovered by everyone. Now, glass is not only used in life, but also in industry, and it has become indispensable. A kind of supplies and materials.

Ordinary glass is also used by some customers and merchants because of its low cost. However, ordinary glass products have poor temperature resistance and are susceptible to bursts due to changes in temperature differences. They have low impact resistance and will break upon a slight collision. Ordinary glass will break when it is broken. , There will be splashes. If there is someone standing next to it, it is easy to hurt people, and ordinary glass fragments have edges and corners, and it is easy to hurt your hands when they are cleaned up. Especially when there are ignorant children in the family, the children will pick up these fragments. It is easy to hurt children.

Glass manufacturers realized the shortcomings of ordinary glass and developed and produced toughened glass. Nowadays, automobiles and most household items use tempered glass. Toughened glass is treated with special processes such as high temperature. The strength is about 5 times stronger than ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is ordinary glass. It is 5-10 times higher than that, the strength is improved, and safety is also improved. After being broken, it will break into uniform small particles without sharp corners. Therefore, there is basically no harm to people, and it is convenient to pack. Some manufacturers use tempered glass with impurities or inadequate processing for profit. Therefore, the same is tempered glass, but there are differences in quality. Inferior tempered glass is not strong against impact and is easy to explode.

How to distinguish between the toughened glass and ordinary glass

1. General toughened glass is marked with tempering marks, in English, or factory name, and horizontal tempering marks are tempered at high temperature. The tempering mark is printed by high-temperature ink on the glass through screen printing. During the glass tempering process, the high-temperature ink is fused with the glass surface. If the tempering mark is not wiped with hydrofluoric acid, it will not be removed (even if hydrofluoric acid is used, it will remain More obvious traces below). Therefore, the easiest way to see whether the glass is toughened is to put a toughened mark on it.

2. The flatness of toughened glass is worse than that of ordinary glass, because the tempered glass will be red after baking at 600-700 degrees, and then it will be cold. Tempered glass is usually a little bend and it is difficult to see clearly when you use it.

There is a gap in the middle, which is toughened glass. No gaps are ordinary glass.

3. Hardness. The hardness of toughened glass is 5-10 times that of ordinary glass. Toughened glass breaks into a granular shape and is not easy to hurt people, while ordinary glass breaks are fast and sharp and easy to hurt people. Tempered glass is not fragile, while the ordinary glass is fragile.

4. The light transmittance distinction. After the glass has been heated to a high temperature, the temperature drops sharply. Tension and stress are generated on the surface of the glass and inside the glass. The glossiness of the tempered glass surface is affected to varying degrees.

Maintenance And Cleaning Skills Of toughened Glass

 Although toughened glass has the advantages of high toughness, bending resistance, and high safety performance compared with ordinary glass, it is essentially glass, and it is easily broken when used improperly. Therefore, the toughened glass supplier reminds you that daily use requires more attention to extend the service life of the toughened glass.

Precautions for toughened glass products　

1. Pay attention to protect the corners of toughened glass　

If the corners of the toughened glass are damaged, the risk of the glass exploding exponentially increases. Because the stress points of the toughened glass are all concentrated at the corners, the protection of the corners is particularly important. You must be cautious when using the toughened glass with broken corners that cannot be handled.　　

2. Avoid keeping toughened glass under pressure for a long time　

For indoor beauty, many families choose to use toughened glass as tabletop dining tables and coffee tables. Generally, toughened glass can withstand pressure between 70mpa and 100mpa. This pressure multiplied by the force area of the glass is the maximum pressure it can withstand. Converted into item quality=(pressure*area)/10. If not necessary, do not place heavy objects on the tempered glass table for a long time to avoid the pressure value reaching the critical point and the toughened glass will break.　　

3. Avoid uneven heat and cold　　

If in extreme conditions, high and low temperatures are applied to both ends of a piece of glass, 90% of the glass will explode. For example, if you pour cold water on a lit incandescent lamp, the glass of the incandescent lamp will break. Although for toughened glass, this situation will be very small, but not afraid of ten thousand just in case.　　

4.Keep away from acid and alkali substances

Avoid contacting the tempered glass with alkaline substances such as sodium hydroxide (NaOH caustic soda) and hydrofluoric acid (HF). The glass is essentially silica (SiO2), which will chemically react with the above substances.

5. It is forbidden to use sharp or hard objects to knock the corners of the glass

Since the stress points of the toughened glass are concentrated at the corners, once the corners are broken, the chance of the toughened glass cracking will increase. Therefore, for the safety of the home, do not use sharp or hard objects to knock the corners of the toughened glass.

Maintenance of toughened glass dining table

1. Avoid exposure and rain　　

If the glass dining table is exposed to the sun and rain for a long time, the seams of the sealing edge will easily crack, which will cause the substrate to expand and deform, and the glass will break. If this happens, only send it back to the factory for repair.　

2. Handle things gently　

Remember not to forcefully hit the glass surface, and when placing things on it, handle it gently. In order to prevent the glass surface from being scratched, it is best to lay a table cloth or table mat.　　

3. Keep it clean to prevent mold　

The toughened glass tabletop should be kept clean frequently to prevent mildew caused by contamination of the tabletop. If mildew occurs, move the dining table to a well-ventilated place, and burn it with electric iron for 2-3 minutes until the mildew disappears.　　

4. Wipe the tea in time　

The tea should be wiped dry in time when it falls on the table surface, otherwise, very unsightly tea stains will be leftover time. To remove these tea stains, you can sprinkle some water on the dining table, wipe it with the tin foil in the cigarette box, and finally scrub it with water.　　

5. Hard cloth and wax to remove burn marks　

Sometimes you accidentally drop a cigarette on the table, leaving unsightly burn marks on the glass surface. You can wrap a hard cloth on a toothpick, gently wipe the burn marks, and then apply a layer of wax to remove burn marks. mark.

Cleaning of toughened glass

1. Daily use of wet towels and newspapers　　

In daily cleaning, you can wipe it with a wet towel or newspaper. A wet towel can wipe off most of the stains, and a newspaper can wipe off the water on the glass surface. Stubborn stains can be wiped off with a towel dipped in beer or warm vinegar. You can also use a glass cleaner. Avoid cleaning with strong acid and alkaline solutions. The surface of the glass is easy to frost in winter. You can wipe it with a cloth dipped in strong saltwater or white wine. The effect is very good.　　

2. Cling film gives the glass a new life　

Greasy-stained glass is very laborious to clean, and only a piece of plastic wrap and a damp cloth can bring the glass back to life. Spray the cleaning agent on the glass and stick a piece of plastic wrap to soften the solidified oil stains. After ten minutes, tear off the plastic wrap and wipe with a damp cloth to wipe off all the oil stains, leaving no traces, as smooth as new.　

If there are oily handwriting on the glass, you can rub it with a rubber soak in water, and then wipe it with a damp cloth to completely remove the traces of the oily pen; if it is painted, you can wipe it with cotton dipped in hot vinegar; wipe the glass with a clean dry cloth dipped in alcohol to make it shine crystal.　

　

3. Fluoride-free toothpaste to clean the ground glass　

Frosted glass and frosted glass with various patterns are also very popular, but cleaning is also a more troublesome thing. To clean the patterned ground glass, you can use a toothbrush, dipped in detergent, or fluoride-free toothpaste, and scrub the stains to remove the stains completely. Cannot use a toothpaste containing fluoride because fluorine will damage the toughened glass.

The toughness of toughened glass is better than that of ordinary glass, but if it is used improperly or lacks maintenance, it may burst and break.

How do I Confirm that My Glass Is Tempered Safety Glass?

 

Tempered safety glass can save lives.

This safety glass is produced using a slower cooling process, and its strength and safety are much higher than standard glass. As tempered glass has a high heat resistance and damage resistance, it is widely favored in the construction and installation of windows. It is also commonly used in aquariums and tabletops as well as protective glasses for divers and mechanics.

To the untrained person, the toughened glass looks the same as any type of glass. In order to identify it, many people will jokingly say: "W! If it is broken into small, bite-sized pieces, then it must have been ground." But seriously, how do you judge whether the glass has been tempered? (No hammer involved)?

Below, we provide you with a less destructive way to determine whether your glass is hard.

Check its edges

Generally, tempered glass has completely smooth edges due to additional processing, while other types of glass usually have scratched or raised edges.

If the edges of the glass are exposed, slide your fingers along them. If the roughness is not caused by abrasion, any rough impression may mean that the glass is not tempered.
Watch out for errors

We don’t mean the insect. In the construction industry, bugs are tiny tags etched or sandblasted on the corners of the glass. This mark, together with the manufacturer's name and CPSC (Consumer Product Safety Commission) standards, indicates whether the glass has been tempered.

If you get the glass directly from the manufacturer, you can easily see the mark. But this is not always the case, especially when the glass frame hides the seal. Therefore, you must beware of other clues.

Looking for flaws

If you find any warpage, bend, or depression on the glass, it is most likely tempered glass. These defects usually occur during heating. Because glass is exposed to extremely high heat, the pliers used to carry the glass usually leave a slight mark on the surface, which can be recognized if you look close enough.

Certain tempered glass may also have surface scratches, usually caused by small particles that melt in the machine roll and fuse to its surface. In the normal cleaning process, this residual debris will be dragged, resulting in slight scratches.

View glass through the polarizer

If you try to view toughened safety glass with polarized sunglasses in the sun, you will see dark, shaded dots or lines extending on its surface-this is the main indicator that the glass is hardened. These lines are formed by steel rollers in the tempering process.

Draw a line (only if you plan to cut it off)

If all other methods fail, consider using a window cutting tool to draw a line on the glass surface. If it produces uneven and scaly lines, it should be adjusted. If you plan to cut glass, please bring it to an expert so that you can cut the glass without cracking or chipping.

Complete Guide: Toughened Glass VS Laminated Glass

 Toughened Or Laminated Glass is popular for its sturdy and reliable quality. They have been specially treated to provide the ultimate safety and standard for home and commercial properties.

However, the difference between these two types is usually unknown, and in fact, they can actually provide the same category, while they each provide different benefits and are more suitable for different things.

What is tempered glass?

The strength of toughened safety glass is five times that of ordinary glass. This is achieved by heating ordinary glass at a high temperature (650°C) and then rapidly cooling it down. Compared with ordinary glass, this process makes it harder (hence the name), and the heat and shock resistance are increased by 400% or 500%.

The purpose of the toughening process is mainly to improve the structural durability and thermal strength of the glass, thereby improving its resilience and heat resistance. It is worth noting that this type of glass cannot be recut after tempering. It must be cut off before the toughening process.

Tempered glass undergoes special treatment and will break into small blunt pieces under pressure, which is safer than ordinary glass fragments.

What is a laminated glass?

Laminated glass technically has the same strength as ordinary glass, but there is a plastic interlayer between two 3mm thick glasses to hold them together. The PVB plastic middle layer is a tough resin. If the glass breaks, it will hold the fragments in place, thus providing a safe double-layer design.

For safety reasons, laminated glass must meet specifications, and the transparency of the glass will not change during the lamination process.

What is the difference between tempered glass and laminated glass?

After looking at the difference between tempered glass and laminated glass, it is clear that both types can withstand greater impact and stress, and can also withstand high and low temperatures. In terms of health and safety standards, this makes them ideal choices.

Due to the existence of the interlayer, laminated glass is thicker than tempered glass, so it can provide better insulation and resistance to accidental or deliberate impact or damage. In other words, laminated glass is heavier and more costly than tempered glass, so it is important to weigh what is most important to you before buying anything.

Benefit

The benefits of tempered glass and laminated glass show the main difference between the two:

Toughened	Laminated
Low-iron Toughened Glass	Low-iron Toughened Glass
Thermal or chemical methods used in the toughening process increase strength, resilience, and the ability to withstand high temperatures.	There is a plastic intermediate layer between the two glass plates, if the glass breaks, the pieces can be fixed in place.
Its strength is at least five times that of ordinary glass, which means that it takes a lot of force to break it.	Because it is not easily damaged, the replacement cost will be kept to a minimum or reduced.
If it breaks, it will break evenly into small pieces, so there will be no shards or glass shards.	It can withstand temperature changes, improve sound insulation, and reduce the impact of harmful ultraviolet rays.
It is superior to standard glass in structure and heat.	Easy to color.
Color, transparency, composition, transmittance, and hardness do not change during toughening.	If the glass is used externally, for example in a shop window, it can act as a protective barrier against strong winds and heavy rain.
The glass may be painted RAL color.	Layered designs provide better insulation and can improve your green credentials and energy efficiency.

Where are they most commonly used?
