2020-07-01  923

Some glasses have special functions, such as thermal insulation, heat insulation, sound insulation, etc. We call such glasses special functions. Common special function glasses are:

Insulating glass   Insulating glass is composed of two or more layers of ordinary flat glass. High-strength, high-tightness composite adhesive is used to bond and seal two or more pieces of glass to the sealing strip and the glass strip, filled with dry gas in the middle, and filled with desiccant in the frame to protect the air between the glass sheets Coal dryness. Its characteristics, because it has a certain cavity, has good thermal insulation, thermal insulation, sound insulation and other properties. Mainly used for outer glass decoration of heating, air conditioning, and noise reduction facilities. Its optical performance, thermal conductivity, and sound insulation coefficient all comply with national standards.

Tempered glass
Tempered glass is also called strengthened glass. It is a method of rapidly cooling after heating to a certain temperature, or special treatment of glass by chemical methods. It is characterized by high strength, strong bending resistance and impact resistance 3-5 times higher than ordinary flat glass. It has good safety performance, uniform internal stress, and a net-shaped crack after breaking. It is mainly used for doors, windows, partition walls and cabinet doors. Tempered glass also has acid and alkali resistance. The general thickness is 2-5mm, and its specifications are generally 400mX 900mm, 500mm X 1200mm.

Wired glass
Wired glass is also called shatter-proof glass. It is made by heating ordinary flat glass to the thermally softened state, and then pressing the preheated iron wire or wire mesh into the middle of the glass. It is characterized by superior fire resistance, can block flames, does not burst when burned at high temperature, and will not cause fragments to hurt people when broken. In addition, it has anti-theft performance, glass breakage and barbed wire barrier. Mainly used for roof skylights and balcony windows.

High performance insulating glass
In addition to sealing dry air between the two layers of glass, high-performance insulating glass is also coated with a special metal film with good thermal properties on the side layer of the outer glass that is in contact with outdoor air. It can block the penetration of solar ultraviolet rays into the Indoor energy. It is characterized by good energy saving effect, heat insulation and heat preservation, and improvement of indoor environment. The appearance has eight colors and is rich in excellent decorative art value.

Glass mosaic
Glass mosaic is also called glass mosaic tile or cellophane brick. It is a small-sized colored facing glass.
