What kinds of glasses must we know when dealing with door and window projects and dry curtain wall projects?

Here are 24 kinds of common glass in the market. Let's have a look!

1. Tempered glass

Toughened glass is a glass product obtained by heating the glass to a temperature close to the softening temperature of glass (600-650 ℃), rapidly cooling it or chemically toughening it. It has good mechanical properties and heat shock resistance. After the original glass is heat-treated in the tempering furnace, its structural performance is improved, and its strength is increased by 3-5 times. It can withstand external impact of certain energy or temperature change without breaking. Even if it is broken, the whole glass is broken into small obtuse angle particles similar to honeycomb, which is not easy to hurt people, so it has certain safety.

11. Laminated glass

Laminated glass is composed of two or more pieces of float glass, one or more layers of PVB, pressurized and heated by high-pressure kilns and other equipment. Because this bonding material has good impact resistance and bonding performance, when the glass is broken by impact, due to the bonding effect of the PVB film sandwiched between the two pieces of ordinary glass, it will not produce sharp fragments like ordinary glass after breaking. At the same time, its PVB intermediate film has the performance of sound insulation and sunlight control, which makes it a new building material with energy-saving and environmental protection functions. The use of laminated glass can not only isolate the 1000 ~ 2000 Hz coincidence noise that can penetrate ordinary glass, but also block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum.

12. Float glass

The process of float production is completed in a tin bath filled with protective gas. Molten glass flows continuously from the tank furnace and floats on the surface of the tin liquid with high relative density. Under the action of gravity and surface tension, the glass liquid spreads out and flattens on the tin liquid surface, forming a flat upper and lower surface. After hardening and cooling, it is led to the transition roller table. The roller of the roller table rotates to pull the glass ribbon out of the tin bath and into the annealing furnace.

13. Heat reflective glass

Generally, heat reflective glass is coated with one or more thin films composed of metals such as chromium, titanium or stainless steel or their compounds on the glass surface to make the product colorful. It has appropriate transmittance for visible light, high reflectivity for infrared rays and high absorption rate for ultraviolet rays. Therefore, it is also called sunlight control glass and is mainly used in buildings and glass curtain walls.

14. U-shaped glass

U-shaped glass (also known as trough glass) is a new type of building energy-saving wall profile glass. It is made of broken glass, quartz sand and other raw materials. It has the characteristics of good daylighting, heat insulation, sound insulation, noise prevention, high mechanical strength, anti-aging and light resistance. The shape is a banner type, with the flavor of the times of straightness, elegance and smooth lines, and has a unique decorative effect. Moreover, the installation is convenient and the comprehensive cost is low. Compared with the ordinary steel plate glass structure, the cost can be reduced by 20% - 40%, the operation volume can be reduced by 30% - 50%, and the consumption of glass and metal can be saved.
