What causes the glass lid to suddenly shatter?

There are many reasons for the glass lid to burst, which can be simply summarized as follows:

1. The influence of glass quality defects, the expansion coefficient of stones.

Smaller than glass, the tangential stress around the stone is in tension. The crack propagation that accompanies stones is very easy to occur, so the glass lid is on its own.

2. The glass surface has defects such as scratches, fried mouths, and deep explosion edges due to improper heating process or improper operation, resulting in the glass pot lid itself.

3. Due to the manufacturing process of the glass lid itself, the glass lid itself is **.

4. The temperature difference of the glass lid is too large, causing the glass lid to be self-sufficient.

Precautions for glass lids**.

1. It is forbidden to let the glass pot lid be used in an environment with a large temperature difference, so as not to cause unnecessary losses.

2. When using the glass lid, you should keep a proper distance from the glass lid, so as to avoid harm to the human body.

3. Cleaning after the glass pot lid should not be carried out with bare hands, and it should be cleaned after wearing gloves.

In fact, the main reason for the self-explosion of the glass cover is the alternation of cold and heat, and the temperature difference is too large, resulting in the "self-explosion" of the glass cover.

Therefore, the glass lid of the Cooking Emperor will be tested accordingly before being sold: the temperature will be raised to 260 degrees Celsius, and then quickly lowered to about 25 degrees Celsius to ensure that the glass lid will not cause any problems before being sold.

Summary. Hello, there are several reasons for the sudden cracking of the glass lid:

1. The impurities in the glass often become the weak point of the tempered glass, forming a different expansion coefficient with the vitreous, resulting in explosion.

2. The surface of the glass is prone to explosion due to defects such as scratches and explosions caused by improper processing or operation.

3. The degree of glass tempering used in some glass lids is not enough, and there will also be explosions.

What causes the glass lid to suddenly shatter?

Hello, there are the following reasons for the sudden rupture of the glass lid: 1. The impurities in the glass often become the weak point of the tempered glass, and the number of leakage sections of the expansion system is different from that of the glass body, resulting in explosion.

2. The surface of the glass is prone to explosion due to defects such as scratches and explosions caused by improper processing or operation.

3. The glass tempering process used in some glass pot covers is not boring enough, and there will also be explosions.

Hello, if you want to solve the problem of the explosion of the glass lid, it is best to buy a heat-resistant glass lid, because the thermal expansion coefficient of this glass is relatively small, and it can withstand the sharp temperature difference of the cover rock.

Just take off the lid of hot water, and don't soak it directly in cold water. The glass pot lid is cracked mainly due to heat expansion and cold contraction.

Maybe it's because the temperature inside is higher than its own temperature. It can't withstand such high temperatures, which is why this phenomenon happens.

1. Fatigue of the object, or long-term use, fine cracks appear, and then continue to accumulate to form cracks! 2. Hot expansion and cold contraction. The temperature difference is too large and too intense, causing the glass object to be deformed to the point where it cannot be restored, and it will crack!

Hello, the lid of the pot is broken, there are signs of disaster in the left eye and the right eye, and the heart is restless, the heart is very impatient, once it is broken, it will be fine.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, the lid of the pot is broken, there are signs of disaster in the left eye and the right eye, and the heart is restless, the heart is very impatient, once it is broken, it will be fine.

I saw the lid of the glass pot shattered on the morning of my move this day.

Broken peace. The omen is not bad.

If you don't break it in front of you, that's fine.

I brushed the lid of the pot after eating last night and put it on the pot, and this morning I saw how the lid of the glass pot would break on the pot.

Hello, look at your displacement, the displacement, the fuel consumption is high, the displacement is not high, acceptable. You can't check the compulsory insurance.

Master, what did you say.

It may be due to external forces, and there is a pot lid to protect you from disasters.

The material of the lid is tempered glass, and the automatic explosion of tempered glass without direct mechanical external force is called the self-explosion of tempered glass, and self-explosion is one of the characteristics of tempered glass.

The causes of self-explosion of tempered glass include: stones and impurities in the glass; The glass contains nickel sulfide crystals with special lithofacies; The glass surface has defects such as scratches, explosions, and edge bursts due to improper processing or operation; Heating or cooling causes uneven stress distribution and deviation in tempered glass; The degree of tempering is too high, etc.

The self-explosion of the glass lid is often caused by improper material selection or design, if you want, you should protect the scene (you can also take pictures), and then apply to the manufacturer for compensation.

The glass lid suddenly shattered, if the quality sold by the merchant is not up to standard, you can contact the return. Generally, glass products have a shelf life, and they can be replaced free of charge within the warranty period.

In the process of processing the glass into the lid of the pot, the flat glass needs to be turned into an arc-shaped shape, at this time the glass will produce stress, and some manufacturers do not have the process of eliminating the stress or the elimination is not complete, the tempered glass lid will change the stress value in the process of use, affected by temperature, external force, etc., when the stress value is higher than a certain value, it is easy to appear in the previous news and experiments said in the first situation.

That is to say, the direct cause of the lid is that the stress of the glass itself is too high, especially when the use of the environment is too fast to alternate between hot and cold, it will cause the glass lid to be fragile.

1. The self-explosion of the glass lid is because tempered glass generally has a certain probability of self-explosion.

2. The expansion of nickel sulfide inside the tempered glass is the main cause of the burst, and the nickel components will be mixed with more or less in the glass processing, and the nickel will be combined with the sulfur contained in the glass to produce nickel sulfide. If the coefficient of expansion of nickel sulfide during production is too different from that of the glass itself, it will burst.

3. Tempered glass is more suitable for making doors and windows of cars and buildings, and is not suitable for making special-shaped curved utensils such as cups and bowls. Otherwise, the chance of a burst will increase.

The glass lid is a type of pot lid, which is usually made of glass, and sometimes the glass lid will suddenly burst during the process of stir-frying. So why does the glass lid burst?

1. Under the influence of glass quality defects, the expansion coefficient of the stone is less than that of the glass, and the tangential stress around the stone is in a tensile state. The crack propagation that accompanies stones is very easy to occur, so the glass lid is **.

2. The glass surface has defects such as scratches, fried mouths, and deep explosion edges due to improper heating process or operation, resulting in the glass lid.

3. Due to the manufacturing process of the glass lid itself, the glass lid is **.

4. The temperature difference of the glass lid is too large, resulting in the glass lid**.

That's it for the introduction of why glass lids burst.
