. The chemical oxide (Na2O. Cao. 6SiO2) that makes up ordinary glass mainly consists of
. Widely used in building wind and shading.
Porcelain, also known as colored glass in ancient times, is a transparent, high strength and hardness, airtight material. Glass is chemically inert in daily environment and will not interact with living things, so it is widely used. Glass is usually insoluble in acids (exceptions:
React with glass to generate SiF4, leading to glass corrosion); But soluble in
for example
. Glass is an amorphous supercooled liquid. The molten glass cools rapidly, and each molecule forms glass because there is not enough time to form crystals.
The simple classification of glass is mainly divided into
And special glass.
There are three main types: introduction method.
(slotted/non-slotted), flat glass and float glass. Float glass is becoming the mainstream of glass manufacturing because of its uniform thickness, flat and parallel upper and lower surfaces, high labor productivity and easy management. There are many varieties of special glass, which are explained according to the common varieties in decoration:
The history of glass
Glass was originally solidified by acidic rocks ejected from volcanoes. Before about 3700 BC, the ancient Egyptians had made glass ornaments and simple glassware. At that time, there was only stained glass, about 1000 BC.
Produce colorless glass. /kloc-in the 0/2 century, commercial glass appeared and began to become an industrial material. /kloc-in the 0 th and 8 th centuries, in order to meet the needs of developing telescopes, telescopes were made.
. 1873, Belgium made flat glass for the first time. 1906, the United States made flat glass and introduced the machine. Since then, with the industrialization and scale of glass production, glasses with various uses and properties have come out one after another. In modern times, glass has become an important material in daily life, production and science and technology.
More than 3000 years ago, a European Phoenician merchant ship loaded with crystal mineral "natural soda" sailed on the Berus River on the Mediterranean coast. The merchant ship ran aground because of the low tide.
So the crew boarded the beach. Some crew members also carry cauldrons and firewood, and use a few pieces of "natural soda" as the support of the cauldron to cook on the beach.
After the crew finished eating, the tide began to rise. They were about to pack up their things and go on sailing when someone shouted, "Come and see, there are some glittering and translucent things on the sand at the bottom of the pot!" " "
The crew took these shiny things to the ship to study them carefully. They found something shiny stuck.
And melted natural soda. It turns out that these sparkling things are natural soda used to make pot supports when they cook. Under the action of flame, they are on the beach.
The crystal produced by chemical reaction is the earliest glass. Later, the Phoenicians put
It was mixed with natural soda and then melted in a special furnace to make glass balls, which made the Phoenicians rich.
Around the 4th century, the Romans began to use glass on doors and windows. By 129 1 year, the glass manufacturing technology in Italy has been very developed.
"China's glass manufacturing technology must not be leaked out, and all the craftsmen who make glass are concentrated to produce glass!"
In this way, Italian glassworkers were sent to an isolated island to produce glass, and they were not allowed to leave the island for life.
1688, a man named Fu Na invented the method of making large pieces of glass. Since then, glass has become an ordinary article.
The glass we are using now is made of quartz sand.

Classification of glass
Simple classification
Glass can be simply divided into flat glass and special glass. There are three main types of flat glass: pulling method (with or without grooves), flat pulling method and float glass. Float glass is becoming the mainstream of glass manufacturing because of its uniform thickness, flat and parallel upper and lower surfaces, high labor productivity and easy management. There are many varieties of special glass, which are explained according to the common varieties in decoration:
First, ordinary flat glass.
1, 3-4 mm glass, mm is also called mm in daily life. When we say 3mm glass, we mean glass with a thickness of 3 mm, which is mainly used for the surface of picture frames.
2, 5-6 mm glass, mainly used for exterior walls, doors and windows and other small areas of light-transmitting modeling.
3, 7-9 mm glass, mainly used in large areas such as indoor screens but protected by borders.
4, 9- 10 mm glass, can be used for indoor large-area partitions, railings and other decoration projects.
5. 1 1- 12 mm glass can be used for ground spring glass doors and some partitions with large crowds.
6. Generally, the glass over 1.5 cm is sold less in the market and often needs to be ordered, which is mainly used for the integral glass wall of the outer wall of the ground spring glass door with a large area.
Second, other glass.
When it comes to other glasses, it is only relative to the classification of flat glass, and the author has no formal classification in the industry. Mainly includes:

. It is a kind of impact-resistant flat glass made of metal wire or metal mesh embedded in glass plate by calendering method. When hit, it will only form radial cracks and will not fall and hurt people. Therefore, it is mostly used in high-rise buildings and factories with strong vibration.
6、
. Adhesive bonding is often used to keep two pieces of glass at a certain interval, with dry air in the interval and repeated use at the periphery.
Sealed type, mainly used for decoration projects with sound insulation requirements.
7、
Generally, it consists of two ordinary flat glasses (tempered glass or other special glass) and an organic adhesive layer between the glasses. When it is damaged, the debris is still attached to the adhesive layer, which avoids the damage of debris splashing to human body. Mostly used in decoration projects with safety requirements.
8、
. In fact, it is.
One, but the glass is high-strength tempered glass with a large number of interlayers. It is mostly used in decoration projects with very high safety requirements such as banks or luxury houses.
9、
. Curved glass made by heating and softening flat glass, molding in a mold and annealing. In some advanced decoration, the frequency is getting higher and higher, and it needs to be booked, and there is no spot.
10、
The manufacturing process is basically the same as that of flat glass, but the difference lies in the molding method.
There is dry air in the middle. It is mostly used in decoration engineering or light-transmitting modeling with heat preservation requirements.

Characteristics of glass
Why is glass transparent?
An important reason: no matter how solid a substance is, it is actually empty if viewed from the inside of an atom. Because inside the atom, the sum of the volumes of the nucleus and the electrons is less than 1000000000. In addition, there is no evidence that nuclei and electrons cannot
Go through! Therefore, transparency is normal!
To understand this complicated problem, we must first understand the following question: Why are some substances opaque?
For opaque substances, we can be divided into four categories:
1. is opaque due to the blocking effect of free electrons: this is why metals are opaque.
2. Opacity caused by substances that can absorb light: The excitation energy of electrons in the molecules of such substances is relatively low, just in the visible range, and there are often benzene rings in the molecules.
Benzidine or other.
The structure of the system can reduce the excitation energy of electrons and make them jump and absorb easily.
Energy. So the light is absorbed.
3. Opacity due to the destruction of the structure of transparent substances. For example, glass is transparent, and
It is opaque; Ice is transparent, but it is opaque when it is smashed. If the structural characteristics of a substance do not conform to 1 and 2, it can transmit light, but if there are many small gaps in its structure, it is white. This is why white objects are opaque.
4, 1, 2, 3 mixed results. The opacity of many objects in reality is caused by this reason.
If there are neither free electrons nor easily excited electrons in the structure of a substance, then the structure of the substance is very tight, and there are not many pores. Then matter can pass through
, is transparent. So the glass is transparent!

Future development of glass
glass
We may all have had this experience: in the hot summer, due to the barrier of glass windows, the hot and bright light that shoots into the room makes people feel more like being trapped in a steamer, upset and dry; It's freezing, and the glass window is like a thick wall, which blocks the warm sunshine outside and makes people feel extremely cold indoors. Although the appearance of air-conditioning freed people from the intrusion of extreme heat and cold, it added a heavy burden to the scarce power resources in modern cities, and the red alarm of power crisis sounded sharply in people's ears. Can you invent a new product that can make people live a warm and comfortable life and save energy? Scientists have brought good news: British scientists have invented a glass that can play the role of air conditioner, which can balance the temperature and make people feel indoors.
Why does this glass have such magical power? According to scientists, it is unique in that its surface is covered with an ultra-thin substance-a mixture of vanadium dioxide and tungsten. When the weather is cold, vanadium dioxide can absorb infrared rays and produce temperature.
So as to improve the indoor temperature; On the contrary, when the temperature outside the window is too high, the molecules of the two combined substances change accordingly, reflecting infrared rays, thus cooling the indoor temperature. On this mysterious floor
The most intelligent core is the 2% tungsten contained in it, which can determine whether vanadium dioxide absorbs heat or dissipates heat.
Speaking of which, you may be fascinated by this magical glass, but it still has some technical "defects", with a dirty yellow-brown thin layer on the surface, which seriously affects its beauty. How to neutralize this color and make it clean is a difficult problem before people. However, scientists are optimistic about this. They predict that this kind of glass will be on the market within five years, and the price will not be much higher than the existing ordinary glass.
easy-clean glass
Things will get dusty when used for a long time, even if it is smooth glass. Over time, it also needs people to clean it up. It is not difficult to clean small pieces of dirty glassware, but it is a troublesome chore to clean the outer window glass. Especially the large glass of high-rise buildings, I'm afraid it's tedious and dangerous to let Spider-Man, a professional cleaning company, do the cleaning. However, in the near future, you can put aside all the inconveniences and dangers of cleaning glass windows, because American scientists have developed a special glass called "Lotus", which can clean itself with the help of the power of nature.
The reason why "Lotus" can "clean itself by bathing" is that it is made by using a special technology and adding special ingredients. Once the dirt is attached to the lotus, under the action of sunlight, electron-hole pairs with strong oxidation ability will be produced on its surface. Then, the electron-hole pair combines with oxygen in the air.
Phase interaction produces negative oxygen ions and hydroxide.
. In a powerful
Lotus decomposes all kinds of organic matter attached to its surface into water and carbon dioxide. Finally, after the baptism of rain, "Lotus" washed away the residual dirt on the surface, and its clean appearance was radiant again.
Maybe someone should worry, because it's powerful.
Will the special substance on the surface of "Lotus" gradually disappear and become ordinary glass again? To this end, the researchers explained that this special substance only played a catalytic role in the whole self-cleaning process and did not lose itself. The coat covered by "Lotus" will never fade.
Anhydrous glass just talked about the self-cleaning glass "Lotus". Now let's know a kind of waterless glass like lotus leaf.
Speaking of lotus leaves, we may not be strangers. In summer, it is like a green arrow, straight out of the water; It is like a graceful Ling Boxian, dancing with the breeze. However, have you noticed that the lotus leaf does not drip, and all the water drops falling on the lotus leaf will slide down along its smooth leaf surface, which is what people often call the "lotus leaf effect". However, this effect does not work on glass as smooth as lotus leaves. If there is dust attached to ordinary glass, when water flows, the dust will absorb these water droplets, and the glass surface will be covered with water droplets. This is also the reason why the glass window is blurred in rainy days. Recently, people finally invented a kind of glass that does not touch water, and the glass can finally produce the "lotus leaf effect".
There is not much difference between the magical non-wetting glass and ordinary glass in structure, but there is a layer of high-tech nano on the surface.
. Don't underestimate this thin nano-coating, it is mixed.
Titanium phosphate compound,
Three kinds of substances, with super hydrophilic, anti-static, anti-fog, anti-condensation and other characteristics. Among them, superhydrophilicity is the most incredible. Water will always flow near the glass surface, and when it meets dust, it will take the dust away, making the whole glass surface drip-free.
This kind of glass is widely used and brings a lot of convenience to people's daily life. For example, drivers and friends no longer have to worry about rainy days, because even if it rains heavily outside the window, it will drip down the glass and will not hinder the sight of the people in front. The listing of glass that does not touch water may completely eliminate wipers. Hope to adopt, typing is not easy.
