It is made of quartz sand, sandstone or quartzite, limestone, feldspar, dolomite and soda ash as the primary raw materials, and is made by crushing, sieving, batching, high temperature melting, forming, annealing, cooling, processing and other processes. Glass is closely related to our lives. Glass began to be used for construction only for lighting. It has developed to today. With the addition of glass types and the improvement of performance, as well as the growing voice of environmental protection and energy saving, construction has raised a higher The requirements are mainly reflected in the following aspects:

(1) Daylighting

Daylighting is a basic requirement for glass construction, but now this requirement is raised even higher, and it is no longer necessary to introduce sunlight into the room. At present, all aspects of lighting angle, visual effects, saving artificial lighting costs, indoor occlusion, glass transparency and image distortion are all required.

(2) Security

In the past, the use of glass in construction did not have a safe concept. A large amount of glass was broken due to natural forces or the impact of the human body, causing personal injury and death, and a large number of spoils. Now China has drawn up relevant safety regulations, which stipulate that there must be a design process before the glass is installed to determine whether the glass will be safe when subjected to wind pressure, thermal stress, hail, falling objects, earthquakes, or human impact.

(3) Energy saving

Now, building energy conservation, as an important part of China's energy conservation plan, has now been mentioned on the agenda. The correct and proper use of glass varieties with energy-saving functions is an important way to achieve energy-saving construction.

(4) Fire prevention

In the fire protection channel of the building, glass with fire protection function must be used. This glass should have a certain degree of light transmittance, and can see the degree of flame spread. Together, it should have the ability to isolate the flame from passing within a certain time, so that the personnel can be smoothly dispersed.

(5) Security

The emergence of bulletproof glass, anti-theft glass and alarm glass plays a role in protecting the financial affairs of personnel, and makes some key entrances and exits and partitions more secure. Now these kinds of glass are being promoted to civil construction, which can remove the unsightly iron windows and iron doors on the building, so that the construction can ensure safety while not losing the beautiful original appearance.
