The glass pot is broken by the spirit, why is the lid of the glass pot broken by itself

External causes that can cause tempered glass to burst include loads, bumps, weld droplets, improper clearances, and edge damage can all lead to tempered glass breakage, although the risk of breakage is low due to the high stress of tempered glass. Tempered glass with clean cutting edges will not be damaged by thermal stress under normal environmental conditions, because they require the temperature difference between the center and edge of the glass to reach 90 -150, and the internal factors that lead to the breakage of tempered glass include stress concentration areas such as edge defects of tempered glass, excessive internal stress of tempered glass and nickel sulfide impurities inside tempered glass. The first two factors are caused by the process control in the processing of tempered glass, and the factor of nickel sulfide is generated in the production process of the original glass.

The inside of the glass may contain nickel sulfide impurities, existing in a small crystal state, under normal circumstances, will not cause glass damage, but because the tempered glass is reheated, the phase state of the nickel sulfide impurity is changed, the high temperature state of nickel sulfide is frozen when the glass is quenched, it may take several years for them to return to the state, due to the nickel sulfide impurities in the low temperature state will produce a volume increase, and local stress concentration will be produced inside the glass, and then the tempered glass self-explosion will occur. However, only a relatively large impurity will cause a self-explosion, and only when the impurity is at the core of the tensile stress can the tempered glass self-explosion occur. Nickel sulfide can occur at any time after production is completed, and the most typical time to cause tempered glass to self-detolate is 4-5 years after the product is manufactured.

It is a problem with the self-made process It may be that the pressure in the body is different during the production process or the pressure in the vitreous is not the same, it is easy to produce a self-explosion phenomenon, but the probability is very small Friend, you won the lottery Hehe.

If not all of the above questions

Then it just means that your luck is too good

This kind of thing can happen

Go buy another one!!

Detailed process. Whether someone else broke it, you don't know.

The bottom of my glass is still broken, and it hasn't leaked.

What's going on.

The glass pot lid is broken, which is a physical phenomenon, the result of cold or heat or self-expansion, and there are many poor quality tempered glass.

If you believe it, if you don't believe it, you don't have it, depending on how you ask, then you will believe it, it's not better not to travel.

Didn't talk that gimbledly

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 nickel components will be mixed in the glass processing, and these nickels 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 automobiles and buildings, but not for special-shaped curved utensils such as cups and bowls. Otherwise, the chance of a burst will increase.

Judging from the broken appearance, 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.

You should use rigid glass, it will explode if it is cooled with water after heating at high temperatures. It's a normal post-screening!

The temperature is too high, the pressure is too high,

Because it wants to bloom in life.

You see your grandmother's sister died, the glass was broken, almost 30 years, and nothing bad happened, when the glass was broken, it was possible to be a supernatural event, according to our method here, the first seven deceased relatives will go home to see, often hear the sound of the house, and can't see people, have you ever had a Yin Niangniang (a person who can pass through the underworld)? You can ask your grandfather how he is doing. Let your mom untie the knot.

Many people from our side went to Jiangxi to ask, and they heard that it was very spiritual.

In fact, it is not okay to think like this, maybe it is just a coincidence, don't care, if you want to untie your mother's heart knot, you should communicate with her, tell her that it was a coincidence, someone died when the glass was broken, this is impossible, coincidentally, remember, it was a coincidence, let your mother believe that it is possible for someone to pass away, let alone the elderly? You can tell your mother like this, when you are old, maybe you will die suddenly one day, the old man looks very energetic today, maybe he will die suddenly tomorrow, this is the normal thing of life, don't think nonsense. As for the fact that the glass is broken, maybe it is some kind of phenomenon that we cannot explain, so don't think about it, and live in peace.

The lid is generally made of tempered glass, which will not be broken in general, and the sudden shattering should be used for a long time, so that it itself becomes weak to temperature changes.

Don't be too superstitious about what is likely to happen in winter.

Tempered glass, that is, the quality may be deviated, and it is not that it has been strongly impacted before.

It should be tempered glass, right?

The lid of the soup pot is tempered glass, and it generally does not break suddenly, and the reason for the rupture should be the poor tempering effect, or the uneven force of the steel ring and handle around the glass.

There are many reasons for this: temperature, quality, and more.

We refer to this phenomenon as the self-detonation of tempered glass. According to incomplete statistics, the self-explosion rate of tempered glass is about 3, but the self-explosion rate of products of different manufacturers is also different, and some can reach about 2%. The causes of self-explosion of tempered glass can generally be attributed to three situations: stress concentration caused by processing defects at the edge of the glass, excessive stress inside the tempered glass, and volume expansion caused by the phase transformation of nickel sulfide (NIS) impurities inside the tempered glass.

The first two factors are due to the process of tempered glass processing, and the factor of nickel sulfide is generated in the production process of raw glass. For the self-explosion of tempered glass, there is no perfect solution at present, and the method of controlling tempering stress and homogenization treatment is generally adopted to reduce the self-explosion of tempered glass. Corresponding to fully tempered glass, if the tempering stress is reduced, the glass produced is also semi-tempered glass.

The probability of self-explosion of semi-tempered glass is much smaller than that of fully tempered glass, therefore, for example, in addition to all-steel glass, semi-tempered glass can also be used for building glass curtain walls. However, it should be noted that the fragment form after the semi-tempered glass is broken is between the fully tempered glass and the ordinary glass, and the fragments are also sharp and angular, so the semi-tempered glass cannot be counted as safety glass. This phenomenon occurs a lot, don't worry.

I was once impacted, and it was not visible to the naked eye at the time, but when I took you to heat it, it expanded after heating, and the lid showed cracks.

I haven't heard of this brand, it may be a quality issue.

Could it be that when it's hot, it's suddenly cold again?

Tempered glass will have a certain probability of self-explosion, and quality, improper processing, impurities, etc., rapid changes in temperature will cause self-explosion.
