[b li]

The world's earliest glass maker is

Have

In addition, glass is divided into: tempered glass,

The main raw materials for glass production are glass forming bodies, glass regulators and glass intermediates, and the rest are auxiliary raw materials. The main raw materials refer to the oxides, intermediate oxides and outer network oxides introduced into the glass to form a network; auxiliary raw materials include clarifying agents,

mainly include:

Raw material pre-processing. Will block the raw material (

Depending on the type, glass has different characteristics. According to the classification method of architectural glass, they are introduced as follows:

1. Do not hit the glass surface with force. Usually, it is better to lay a table cloth to prevent the glass surface from scratching. in

Glass is not completely solid

Glass is neither crystalline, amorphous, nor polycrystalline, nor mixed. The theoretical name is

Glass is an ancient building material. With the rapid improvement of modern science and technology and the rapid development of applied technology, various unique functional glasses have come out one after another, and the glass family has flourished.

The glass is not broken

A British aircraft manufacturing company invented an unbreakable glass for aircraft, which is a multilayer glass with debris clad into a transparent plastic film. This PVC-based plastic film has a viscous semi-liquid consistency. When someone tries to break it, the hit PVC film will slowly gather together and restore its unique integrity. This glass can be used in cars to prevent theft.

Glass bulletproof

Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. It is usually a transparent material, such as PVB / polycarbonate thermoplastics (generally Lexan resin or Lexan resin). Also called LEXAN PC RESIN). It has the appearance of ordinary glass and the behavior of transmitting light, providing some protection against the shooting of small arms. The thickest pc board can be 136 mm thick, the maximum width is 2166 mm wide, and the effective time is 6664 days.

Nailable glass

The glass developed by Mitsubishi Electronic Instruments Laboratory in Japan is made by mixing borate glass powder and carbon fiber and heating it to 1000 degrees Celsius. It is a glass reinforced with cemented carbide. Its maximum breaking stress is more than twice that of ordinary glass. There is no brittleness and weakness. Do not worry about breaking.

Non-reflective glass

The non-reflective glass developed by the German SCHOTT glass company has a light reflectivity of less than 1% (typically 8% for glass), thereby solving the problems of glass reflection and dizzying headaches.

Anti-theft glass

The glass developed by a Hungarian research institute has a multi-layer structure, and each layer is embedded with a very thin metal wire. In the event of a thief breaking the glass, the alarm system connected to the metal wire will immediately send an alarm signal.

Acoustic glass

A Japanese company introduced technology from Germany to make a new type of soundproof glass. This kind of glass is bonded with two layers of glass with a soft resin up to 5 mm thick, which can absorb almost all noise, which is especially suitable for recording studios and studios. Its price is equivalent to 5 times that of ordinary glass.

Air-conditioning glass

This is a kind of double glass processing, which can send the heating to the glass interlayer and distribute it to the room through the air holes instead of the radiator. This not only saves energy, but also is convenient, soundproof and dustproof, and can be changed to air-conditioning in summer.

Vacuum glass

This kind of vacuum glass developed by Japan Flat Glass Co., Ltd. is a vacuum layer with a 1/100 atm pressure between two pieces of glass with a thickness of 3 mm. There is a small metal cylinder inside the layer to prevent the external atmospheric pressure from causing the two Pieces of glass stuck together. This vacuum glass is only 6.2 millimeters thick and can be mounted directly on general window frames. It has good heat insulation and sound insulation effects, and is suitable for windows of residential houses and high-rise buildings.

Smart glass

The transparency of this kind of glass developed in the United States can change with the change of the viewing angle. It has a special polymer film. Its astigmatism, thickness, area and form can be freely selected by the manufacturer. It can be used to protect it. And shielding effect.

Holographic glass

A holographic diffractive glass developed by a research team in Boston, USA, can focus certain colors of light to a selected orientation. With this glass window, natural light can be decomposed into a spectral combination color, and the light is directed to the ceiling and reflected to all corners of the room. Even in a room without a window, the sunlight can be "obtained" from the reflecting wall through a ventilation duct, and then Eyelets diffuse light onto the ceiling.

Tempered glass

A British company successfully developed a thermo-varying tinted glass called mastic, which is a synthetic glass with a plastic film on both sides and a polymer water-colored solvent sandwiched between them. It is transparent in a low temperature environment and absorbs the thermal energy of sunlight. When the ambient temperature rises, it becomes an opaque white cloud color and blocks the thermal energy of sunlight to effectively regulate the indoor temperature.

Bioglass

The University of Florida has developed a new type of bioglass with a combination of bioactive energy and active tissue. This bioglass is biocompatible and can be used in areas such as artificial bones and artificial gums.

Antenna glass

A Japanese company has successfully developed a TV antenna window glass. This glass has a thin antenna embedded in it. After installation, the indoor TV can show a clearer picture.

Tissue paper glass

German scientists have produced an ultra-thin glass that can be used in optoelectronics, biosensors, computer displays and other modern technological fields. Its thickness is only 0.003 mm.

Information glass

Tokushima University in Japan invented a glass that can record information. When it records information, first use an optical microscope to focus the laser on a certain point inside the glass, and complete one irradiation in 30 picoseconds, leaving a recording spot. When reading information, it is performed by laser scanning the spot. This kind of recording information can be performed at normal temperature, and its performance is higher than that of the optical discs used by everyone.

Stained glass

The California Air Pollution Observation Laboratory has developed a stained glass that can detect pollution. This glass can change color when polluted by pollution gas, for example, it becomes green when polluted by acid gas, yellowish gray when polluted by amine-containing gas, etc. It will be widely used to make pollution detection materials and labeling materials. .

CO2 glass

The Japan Institute of Industrial Technology's Osaka Institute of Industrial Technology has developed a glass film that is permeable to carbon dioxide, and applied it to the glass window of the living room to discharge the indoor carbon dioxide gas outdoors. It transmits different amounts of carbon dioxide under different humidity. The higher the humidity, the higher the permeability.

Electrolyzed Atomized Glass

Electrolytic atomized glass has the functions of scratch resistance, scratch resistance, comfortable and soft touch, without sweat stains and fingerprint printing. It changes the cold and stiff look of traditional glass. Its biggest feature is that the electrolytically atomized glass will automatically generate a surface atomizing effect after it is powered on, and it will instantly change the transparency, and it will look like an ordinary white wall on the outside. Japanese transparent public toilet is the effect of applying electrolytic atomized glass.

Foam glass

Bulgarian building materials experts have successfully developed a foam glass that has good biological stability, does not rot, has poor hygroscopicity, is easy to process, and is easy to bond with other building materials. This new type of foam glass is successfully manufactured on the basis of liquid glass with various mineral components.

Self-cleaning glass

The University of Tokyo in Japan invented a titanium dioxide-coated glass, which can prevent dirt and water spots from accumulating on the surface, can achieve automatic cleaning and shockproof effects, and can clean glass windows without effort.
