Glass is still glass when it is broken, and when a heart is broken, it can t be called a human being

The glass is broken, there is no way to heal, sticky?

The heart is broken, and the heart is an organ, made up of cells, and it is possible to restore it intact.

But this heart is not the other's heart.

There was nothing to stir up dust.

Broken glass is still glass, broken heart is still heart. Is there anyone?

Time will restore it for you, but don't forget that your heart belongs not only to him or her, but also to your relatives and friends, please don't break their hearts again, you know.

Broken glass is called broken glass, but it can be restored. When a heartbreak is broken, it is called a broken person, but the human heart is fleshy, and it will heal automatically after a while!

Glass is made by melting quartz in sand at high temperatures.

Quartz is a crystal.

It's inherently fragile.

Although he changed his form, the structure of the crystals did not become stronger.

Because the gravitational force between the glass molecules is too small, the repulsive force is opposite.

As soon as it hits the glass molecules, it is easy to separate, that is, the glass is easy to break.

Summary: Glass is fragile.

It is because the glass is too hard, it is a brittle material, and the plasticity is poor.

In layman's terms: if the glass falls on the ground and is impacted, it will be deformed, but the ability of the glass to be hard deformed is too poor.

It's broken (it can also be understood as deformed).

The corresponding is the dough: if it falls on the ground and is impacted, it will be deformed, and the dough is soft and has a good ability to deform, so it will flatten and fall on the ground.

Possibly, but unlikely. Because glass is a mixture with silicates and large amounts of silica and other impurities, there are no natural frequencies. But for quartz glass, there is, between 20000*(1+8%)Hz.

The frequency of the human vocal cords is generally not higher than 2000Hz, so it is rare to shatter the glass (resonate), but there are some special sopranos whose vocal cord frequency can reach a degree very similar to the frequency of the glass, thus vibrating the glass, but this situation is relatively rare.

Each substance has its own natural frequency, and when external vibrations are close to or equal to its natural frequency, the object resonates and can be shattered.

Someone asked before.

The argument of the literary point is that it is too transparent, easy to be sad, and therefore fragile.

The essence is because it is small.

The glass is too hard, the deformation ability is poor, and the plasticity is poor!

Glass is susceptible to discrimination. Now this society glass has no future for development. Only learn Leslie Cheung. o( o haha

There are two types of broken glass: one is when it is hit by an external force, and its force is greater than the strength (bearing force) of the glass, and it is broken. The other is that each substance does not need to expand the number of grains, and the number of glass expansion grains used in ordinary times is larger, so when the heating is uneven, or the sudden cold, or the sudden heat causes the glass to burst and break.

However, there is a kind of quartz glass that has a very small expansion and will not break when heated at a high temperature and suddenly put into water!

1.Tempered glass has the property of self-explosion.

This is because the glass raw material contains nickel sulfide crystals, which cannot be completely avoided by any existing manufacturing technology in the world, and can only slightly reduce the probability of self-explosion by controlling the purity of the raw material and the processing technology.

As far as the concept of self-explosion rate is concerned, there are only national standards for the engineering glass of the exterior wall in our country, and I don't know if there are detailed regulations for the tempered glass used in other industries abroad.

There are at least 3-4 nickel sulfide crystals in a ton of glass raw materials, and after this ton of glass is made into several pieces of glass with a size of one square meter, there will be 3-4 pieces of self-explosion, which is the image of self-explosion.

2.There are many inducing factors for the self-explosion of tempered glass.

a.For example, whether there is accidental damage to the glass before installation, such as chipping, knocking off the foot, etc., because the surrounding range of tempered glass is a weak tempered area, and its strength is even weaker than that of non-tempered glass, but this part of the damage is likely not to cause the immediate cracking of the glass, but it changes the internal stress of this piece of glass. When the upper wall is used, its internal stress gradually changes, causing the glass to break.

b.For example, the difference in temperature change after installation. Just like you said, the temperature, the weather, etc., will make the internal compressive stress of the glass uneven, which will cause bursting.

c.Installation is not the correct size. If the installation is too tight and the specifications are not suitable, it will cause the internal stress of the glass to change and cause bursting.

d.The rest is external force, including impact, extrusion, etc. It's not just the impact of manpower, or other objects, or even the wind force in nature, etc.

If the glass doesn't fall to the ground, there will be obvious impact points, (if it's a self-explosion, there will be butterfly spots), these can be used as a matter, but if it is in a lawsuit, it can only be said to be a possibility, because you have no evidence to prove it. In this case in China, glass manufacturers generally compensate for the glass.

The main thing I want to tell you is that you have to emphasize that the glass itself has the property of self-detonation, which is inevitable for anyone. If your friend is only installing, not producing, then you must not say that you have a bump, but also emphasize that the installation is strictly in accordance with the size, which is the problem of the glass itself. If your friend is still responsible for the production, compensation for the glass is inevitable, but whether it hurts, you have to negotiate, generally speaking, fifty-fifty points, the domestic experience is that the manufacturer will compensate a little, but will not be completely in accordance with the amount of compensation for the injured.

The natural breakage of the front glass of a car is still a relatively common occurrence. It is mainly caused by the thermal expansion and contraction of automobile glass, when the glass is installed, there is not enough gap, and the glass expands when it is preheated, and the top reaches the iron side, and the force is uneven, so the glass is broken.

After the laminated and tempered glass is finally formed, there is a compressive stress balance inside the glass. Generally, matching glass has compressive stress standards. In order to adapt to the climatic conditions of various places, to prevent the receipt of external forces, compressive stress imbalance, resulting in glass self-explosion.

However, not every piece of glass is within the compressive stress range without bursting. It is also related to external forces and natural conditions.

Laminated glass is broken like this.,Sometimes you look at a little bit and it cracks overnight.。。。

First of all, look at whether the detonation point (the cracks of the tempered glass are radial, and there are starting points) is in the middle of the glass, such as at the edge of the glass, generally because the glass has not been chamfered and edging or the edge of the glass is damaged, resulting in stress concentration and the gradual development of cracks; If the detonation point is in the middle of the glass, see if there is a pattern similar to two butterfly wings (butterfly spots) composed of two small polygons at the detonation point, and if you carefully observe that the common edge of the two small polygons (the trunk part of the butterfly) should have small black particles (nickel sulfide stones) visible to the naked eye, it can be judged to be self-detonating; Otherwise, it should be destroyed by external forces.

There is no certainty in the self-explosion time of tempered glass, it may be just out of the oven, or it may be 1-2 months after leaving the factory, and there are also 1-2 years before the factory self-explosion, and the time for more self-explosion of tempered glass may be 4-5 years after the completion of product production.

According to incomplete understanding, the probability of most manufacturers' products is 3 per 1,000 of the self-explosion rate of left and stone; The probability of individual manufacturers' products may be even higher.

The fundamental reason for the self-explosion of tempered glass is because the glass contains nickel sulfide impurities.

The results that can result from broken glass:

1.loss of a piece of glass.

2.Loss of a hundred gold coins.

3.Stabbing someone.

4.Causing family panic and then threatening the life and health of family members.

5.The landlord will be sad.

6.Waste of resources.

To sum up, two conclusions are drawn.

1 Cherish glass and protect the planet.

2 Be sure to protect the glass The consequences are serious.

It is easy to stab and hurt people, so quickly clean up the debris, and be sure to remove it thoroughly to avoid future troubles.

It depends on what kind of glass, tempered glass is not easy to fall when it is broken, and ordinary ones fall to the ground.
