Among them, ultra-white float glass has a wide range of uses and broad market prospects. It is mainly used in the fields of high-end construction, high-grade glass processing and solar photovoltaic wall, as well as high-grade glass furniture, decorative glass, crystal products, lighting glass, and precision electronics. Special construction and so on. Then, where is the difference between float glass and ordinary glass? Let's go and see it together.

What is float glass?

It is prepared with sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials. After melting at a high temperature in the melting furnace, the glass liquid continuously flows from the tank kiln to the surface of the metal liquid and spreads into a flat, flame-stripped glass ribbon. , After cooling and hardening from the molten metal, and then cut through the annealed transparent colorless plate glass.

The forming process of float production is done in a tin bath that is protected by a protective gas. Float glass is widely used, divided into colored glass, float silver mirror, float glass/auto windshield grade, float glass/various deep processing grade, float glass/scanner grade, float glass/coating grade, float French glass / mirror grade. Among them, ultra-white float glass has a wide range of uses and broad market prospects. It is mainly used in the fields of high-end construction, high-grade glass processing and solar photovoltaic wall, as well as high-grade glass furniture, decorative glass, crystal products, lighting glass, and precision electronics. Special construction and so on.

Float glass advantages:

First, the float glass is in the tin bath, and the glass floats on the surface of the tin liquid. Therefore, this kind of glass is first flat and has no ripples. For mirrors, automotive glass, do not shape, this is a big advantage.

Followed by the quartz sand used for float glass, the raw materials are good. The glass produced is pure and transparent. Bright and colorless. There are no glass bottles, bubbles, and the like.

The third is that the structure is tight, heavy, and feels smooth. The same thickness is greater than the flat plate per square meter, which is good for cutting and is not easy to damage.

In addition, more than 200 production lines throughout the country are produced in strict accordance with national standards. This glass is the best glass for civil buildings. Its price, compared with the same thickness, is only 4 yuan higher than flat glass per square meter, the price is more affordable.

The difference between float glass and ordinary glass:

The differences between flat glass and float glass are as follows:

A: Common flat glass and float glass are flat glass. Only the production process and quality are different. Ordinary plate glass is made of quartz sandstone powder, silica sand, potassium fossil, soda ash, mirabilite and other raw materials, prepared by a certain proportion, melted at a high temperature in the melting furnace, and produced by the vertical lead method or the flat pull method and the calendar method. plate glass. Ordinary flat glass is divided into special products, first-class goods, and second-class goods according to the appearance quality. According to the thickness is divided into five kinds of 2,3,4,5,6mm.

B: Float glass is made of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials, prepared by a certain proportion, melted at a high temperature in a melting furnace, and the glass liquid continuously flows from the pool kiln to the surface of the metal liquid, and is distributed. Uniformly flat, fire-polished glass

Glass ribbon, after cooling and hardening, it is separated from metal liquid, and then it is cut through annealing to form a transparent and colorless plate glass. The glass surface is particularly smooth and flat, and its thickness is very uniform. Optical distortion is very small. Float glass is classified according to appearance quality into excellent products, first grade products and qualified products. According to the thickness is divided into 3,4,5,6,8,10,12,15,19mm nine kinds.

C: The quality level of ordinary flat glass is judged by the number of defects such as ribs, air bubbles, scratches, sand, blemishes, and lines. The appearance quality grade of float glass is judged by the number of defects such as optical distortion, bubbles, inclusions, scratches, lines, and fog.

D: ordinary glass, emerald green, fragile, low transparency, easy aging and deformation under rain exposure. Float glass and transparent float glass are glass pastes that enter the tin bath through the control gate. After floating on the surface of the molten tin due to gravity and its surface tension, it enters the cold sink, making the glass on both sides smooth and even, and the ripples disappear. production. Dark green, smooth surface without corrugation, good visibility, with a certain degree of toughness.

E: The production process of float glass and ordinary glass is different. The advantage is that the surface is hard, smooth and flat. The color of the float glass is different from that of ordinary glass on the side, white, and the object is not distorted after reflection. In general, there are water marks. Type deformation.

Editor's summary: The relevant information about what float glass is and the difference between float glass and ordinary glass is introduced here. I hope this article helps everyone.
