What is the difference between float glass and ordinary glass in float glass

Among them, ultra-white float glass is widely used and has broad market prospects. Mainly used in high-end construction, high-end glass processing, solar photovoltaic walls and other fields, as well as high-end glass furniture, decorative glass, crystal products, lighting glass, precision electronics and other fields. Special construction, etc. So, what is the difference between float glass and ordinary glass? Let's go see it together.

What is float glass?

It is prepared with sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials. After the molten glass is melted at high temperature in the furnace, it continuously flows from the kiln to the surface of the molten metal and spreads into a flat, flame-stripped glass ribbon. After cooling and hardening from molten metal, it is then cut through annealed transparent colorless flat glass.
The formation process of float production is done in a tin bath protected by a shielding gas. Float glass is widely used, divided into colored glass, float silver mirror, float glass/automobile windshield grade, float glass/various deep processing grades, float glass/scanner grade, float glass/coating grade, Float French glass/mirror grade. Among them, ultra-white float glass is widely used and has broad market prospects. Mainly used in high-end construction, high-end glass processing, solar photovoltaic walls and other fields, as well as high-end glass furniture, decorative glass, crystal products, lighting glass, precision electronics and other fields. Special construction, etc.

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 glass is first of all flat, without corrugations. For mirrors, car glass, do not shape, this is a big advantage.
Followed by quartz sand for float glass, the raw material is good. The glass produced is pure and transparent. Bright and colorless. No glass bottles, bubbles, etc.
Third, the structure is tight, heavy and smooth. The same thickness is larger than the flat plate per square meter, which is conducive to cutting and not easy to damage.
In addition, more than 200 production lines across the country are produced in strict accordance with national standards. This kind of glass is the best glass for civil buildings. Compared with the same thickness, its price is only 4 yuan per square meter higher than that of flat glass, and 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.
