the earliest human society
packaging materials and decorative materials,
It has existed on earth for thousands of years.
As early as 3700 BC,
ancient egyptians made glass ornaments
and simple glassware.
modern society,
Glass continues to promote the progress of human society,
From the telescope of human exploration of space
Optical glass lens used

Bring the light source glass,
All reflect the important role of glass materials.
In today’s society,
Glass is integrated
every aspect of our lives.
In the traditional daily consumption field,
The glass material brings practicality,
At the same time, it adds beauty and sentiment to our lives.
In the field of consumer electronics,
mobile phones, computers,
LCD TV, LED lighting and other electronic products
There is no need for the excellent properties of glass materials.
In the field of pharmaceutical packaging,
Glass is closely related to our health.
In the field of new energy development,
It is inseparable from the help of glass materials.
Photovoltaic glass from photovoltaics
to building energy-efficient glass
As well as vehicle display glass and automotive glass,
Glass materials in more subdivisions
has an irreplaceable role.
During more than 4,000 years of use,
Glass and Human Society
Harmonious coexistence and mutual promotion,

Every development and progress,
There are glass materials.
The raw material source of glass is green
Among the silicate compounds that constitute the main structure of glass, silicon is one of the most abundant elements in the earth’s crust, and silicon exists in the form of minerals in nature.
The raw materials used in glass are mainly quartz sand, borax, soda ash, limestone, etc. According to different glass performance requirements, a small amount of other auxiliary raw materials can be added to adjust the glass performance.
These raw materials are harmless to the environment when protective measures are taken during use.
Moreover, with the development of glass technology, the selection of raw materials has become a non-toxic raw material that is harmless to the human body and the environment, and there are mature safety protection measures in the use process to ensure the green and healthy nature of glass raw materials.
The production process of glass mainly consists of four steps: batching, melting, forming and annealing, and processing. The entire production process has basically achieved intelligent production and control.
The operator can set and adjust the process parameters only in the control room, and implement centralized monitoring of the entire production process, which greatly reduces the work intensity and improves the working environment of the workers.
During the production of glass, a number of quality and emission monitoring points have been established to monitor gas emissions during the production process and strictly ensure that glass production meets the national environmental protection standards.
At present, in the production process of glass, the main sources of heat in the glass melting process are clean energy, which are vigorously advocated by countries such as natural gas fuel and electricity.
With the development and progress of glass production technology, the application of oxyfuel combustion technology and electric melting technology in glass production has greatly improved thermal efficiency, reduced energy consumption and saved energy.
Since the combustion process uses oxygen with a purity of about 95%, the content of nitrogen oxides in the combustion products is reduced, and the heat of the high-temperature flue gas generated by the combustion is also recovered for heating and power generation.
At the same time, in order to better reduce pollutant emissions, the glass factory has carried out desulfurization, denitrification and dust removal treatment on the flue gas to minimize emissions.
The water in the glass industry is mainly used for production cooling, which can realize water recycling. Because the glass is extremely stable, it will not pollute the cooling water, and the glass factory has an independent circulation system, so the whole production process will not produce any waste water.
