What is ordinary float double glazing and what is the difference between float glass and ordinary gl

Double-glazed insulating glass windows are made from flat glass produced by float process.

Make no mistake upstairs!

Float is a production process for flat glass, which refers to the natural flattening of glass in a liquid metal tin bath. Since the density of molten glass is less than that of metal tin and will float on the surface of the molten tin, the glass produced by this process is called float glass. At present, almost all ordinary flat glass uses the same process.

As for whether it is used to make automotive glass or architectural glass, it depends on the quality grade of the glass. Float is not a level!

Gefa glass is also a production process. Refers to the process of vertical lead to flat glass, the flatness of which depends on the accuracy of the metal clamp roller.

Glass can be added, no matter which process can be added. The amount of waste glass in the foreign glass industry can be as high as 70%, and there is no impact on the quality of the glass. Due to the influence of chemical composition, it is difficult to melt again, and certain new materials must be added.

Float refers to a grade of glass! The best is the automotive-grade float, then the architectural-grade float, again the lattice glass, and the worst is the recycled glass!

If the double layer is used for plastic steel glass, it will refer to insulating glass! 2 layers of float glass Glued with a sealing strip in the middle! It's insulating glass! It can play the role of thermal insulation and sound insulation.

You mean insulating glass! The hollow is sealed and has the function of heat insulation and heat retention. Double-layered without sealing does not have this effect.

Float glassRefers to flat glass produced by float molding. The glass melt flows from the furnace into a tank containing molten tinMolten glassIt is self-flattened on the surface of the bright and smooth molten tin, and is prepared by pulling and cooling. Its surface is flat and its thickness is uniform.

Float glass is in a tin bath, and the glass floats on the surface of the tin bath. Therefore, this glass is first and foremost flat.

Well, no water ripples. It is often used in mirror making and automobile glass, and has the advantage of not being out of shape.

Secondly, the ore quartz sand used for float glass.

The raw materials are good, the glass produced is pure, transparent, and has the advantages of bright, colorless, no glass boils, bubbles and so on.

In addition, the float glass has a tight and heavy structure, a smooth feel, and the same thickness per square meter is heavier than that of a flat plate, which is easy to cut and not easy to break.

According to different application ranges, float glass is classified as tinted glass, float silver mirror, float glass automobile windshield grade, float glass various deep processing grades, float glass * instrument grade, float glass coating grade, float glass mirror grade.

Among them, ultra-clear float glass has a wide range of uses and broad market prospects, mainly used in the field of construction, glass processing and solar photovoltaic curtain wall, as well as glass furniture, decorative glass, crystal products, lamp glass, precision electronics industry, special buildings, etc.

1. Different raw materials: ordinary glass uses silica sand, potassium fossil, soda ash and other raw materials, while float glass uses sea sand, dolomite, etc.

2. The production process is different: ordinary flat glass Nison fires all the well-proportioned raw materials at high temperature, and then makes them by vertical lead or flat drawing, while float glass is also melted at high temperature, but it needs to be made by multiple cumbersome processes such as polishing, cooling and annealing cutting, so the surface is very flat and smooth. There are 9 thicknesses.

3. Different quality: The quality of ordinary flat glass is divided into excellent products, first-class products and qualified products, and the thickness is mm. It is not transparent and fragile, and it is easy to age under wind and sun.

The thickness of float glass can be divided into 9 specifications, which not only has a transparent and delicate surface, but also has a certain toughness and is not easy to break.

What are the advantages of float glass.

Float glass is in a tin bath, and the glass floats on the surface of the tin bath. Therefore, this kind of glass is first of all flat, without water ripples, and is used for mirror-making and automotive glass. It doesn't make a face, it doesn't get out of shape, which is one of its great advantages.

The second is the ore quartz sand selected for float glass, which has good raw materials, pure and transparent glass, bright and colorless, and no glass boils and bubbles.

The third is that the structure is tight, heavy, smooth feel, the same thickness per square meter is heavier than the flat plate, good cutting, not easy to break, more than 200 production lines in the country are produced in strict accordance with national standards, this glass is the best glass for civil buildings. Compared with the same thickness, it is only about 4 yuan per square meter higher than flat glass.

What are the uses of float glass.

Float glass is widely used, and is divided into tinted glass, float silver mirror, float glass, imitation curved automobile windshield grade, float glass various deep processing grades, float glass scanner grade, float glass coating grade, float glass mirror making grade. Among them, ultra-clear float glass has a wide range of uses and broad market prospects, mainly used in high-end buildings, high-end glass processing and solar photovoltaic curtain wall fields, as well as high-end glass furniture, decorative glass, crystal products, lamp glass, precision electronics industry, special buildings, etc. Therefore, there are still many uses of float glass, and it can be said that it is now a more mainstream cluster of new technology products.

The difference between float glass and ordinary glass: different raw materials, different production processes, and different quality.

1. The raw materials are different

First of all, float glass is different from ordinary glass raw materials, ordinary glass uses silica sand, potassium fossil, soda ash and other raw materials. The raw materials of float glass are sea sand, dolomite, etc.

2. The production process is different

Ordinary flat glass is made by burning all the well-proportioned raw materials at high temperatures, and then made by vertical lead or flat drawing. Although float glass is also melted at high temperatures, it needs to be made through many tedious processes such as polishing, cooling, annealing and cutting, so the surface is very flat and smooth. There are 9 thicknesses.

3. The quality is not the same

The quality of ordinary flat glass is divided into excellent products, first-class products and qualified products, and the thickness is mm. It is not transparent and fragile, and it is easy to age under wind and sun. The thickness of Xunying float glass can be divided into 9 specifications, which not only has a transparent and delicate surface, but also has a certain toughness and is not easy to break.

Float glass uses

Float glass is widely used, which is divided into tinted glass, float silver mirror, automobile windshield grade, various deep processing grades, scanner grade, coating grade, and mirror making grade.

Among them, ultra-clear float glass has a wide range of uses and broad market prospects, mainly used in high-end buildings, high-end glass processing and solar photovoltaic curtain wall fields, as well as high-end glass furniture, decorative glass, crystal products, lamp glass, precision electronics industry, special buildings, etc.

Therefore, there are still many uses of float glass, which can be said to be a new process product that is more mainstream now.

1. Different raw materials: First of all, float glass and ordinary glass raw materials are different, ordinary glass uses silica sand, potassium fossil, soda ash and other raw materials. The raw materials of float glass are sea sand, dolomite, etc.

3. The quality is different: the quality of ordinary flat glass is divided into excellent products, shed trillion first-class products and qualified products, and the thickness is mm. It is not transparent and fragile, and it is easy to age under wind and sun.

The thickness of float glass can be divided into 9 specifications, which not only has a transparent and delicate surface, but also has a certain toughness of macro and tomb, and is not easy to break.

Float glass refers to the glass that is formed by float production in a tin bath that is fed through the shielding gas of the first skin.

Float glass is widely used, and the rebate is tinted glass, float silver mirror, float white glass, etc. Among them, ultra-clear float glass has a wide range of uses and broad market prospects, mainly used in high-end buildings, high-end glass processing and solar photovoltaic curtain wall fields in the world and high-end glass furniture, decorative glass, crystal products, lamps and lanterns, precision electronics industry, special buildings, etc.

Float glass, due to the uniformity of the thickness is better, the transparency of the product is also relatively strong, so after the treatment of the tin surface, it is relatively smooth, and under the action of flame and polishing under the action of smoothness, a glass with a relatively neat surface, good flatness and strong optical properties has been formed. This float glass has the characteristics of good transparency, brightness, purity, and bright indoor light, and is also the best preferred material for building doors and windows, natural lighting materials, and is one of the most widely used building materials.

Float glass is a manufacturing process. It refers to glass made by the floating method, and the general principle is to pour the molten glass onto the surface of the liquid (liquid tin) with a specific gravity greater than the molten glass to form the glass.

Compared with other mechanical manufacturing methods, it has the advantage of reducing the occurrence of uneven glass or bubbles caused by mechanical vibration, and it is theoretically possible to create an infinite length of glass by continuously adding liquid glass to the surface of the liquid.

The molding process for float glass production is done in a tin bath through which shielding gas is fed.

Under the action of gravity and surface tension, the molten glass spreads, flattens, forms a flat upper and lower surface, hardens and cools the upper and lower surfaces, and is led to the transition roller table. The roller of the roller table rotates, pulls the glass strip out of the tin bath and enters the annealing kiln, and after annealing and cutting, the flat glass product is obtained.
