With the continuous development of society, the problem of noise pollution has become more and more serious. In particular, the traffic noise in the city continues to plague our normal daily life, work and study. The performance of glass as an indoor and outdoor spacer is also constantly optimized and diverse. Various kinds of soundproof glass have been continuously researched and developed. In this issue, Xiao Bian will introduce in detail the types of soundproofed glass and the aspects to be paid attention to when purchasing it. Let's understand it together.
| Â Sound insulation glass sound insulation principle |
Various outdoor sound sources generate vibrations and generate noises. The noise propagates through the air medium. When the noise is transmitted to the soundproof glass doors and windows, the sound insulation glass is successively attenuated. Especially when the noise passes through the sound insulation damper, intermediate frequency noise and high frequency noise are Sound-absorbing damping rubber absorbs, twists, damps, and attenuates, effectively filtering mid-range and high-frequency noise, and finally entering the room with only 5% noise. According to the level of external noise, using different soundproof glass combination schemes, the general indoor can reach the highest national quiet standard (0-level noise standard).
| Â Sound insulation glass classification |
Sound insulation glass can be roughly divided into the following three categories according to the manufacturing process: 1. Insulating glass 2. Vacuum glass 3. Laminated glass.
1. Insulating glass is composed of two layers of glass, surrounded by a high-strength, high-tightness composite adhesive to seal glass and sealing strips and glass strips. The middle layer is filled with 6-9mm air layer to dry gas. The interior is filled with a desiccant to ensure the air dryness between the glass sheets. As shown. Its characteristics, due to leaving a certain cavity, and has a relatively good insulation effect, so it is widely used in northern cities.
In terms of sound insulation performance, high-frequency noise in hollow glass (such as human voice, school tweeter sound, etc.) has a good sound insulation effect, but it has an effect on low frequency noise (such as bus engine noise, train noise, aircraft noise, etc.) It is not obvious, because the air cavity of the hollow glass will resonate with the low-frequency noise of the outside world in the low-frequency area, and low-frequency noise will easily pass through the glass into the room.
2, vacuum glass is generally composed of two layers of 4mm thick flat glass, two layers of glass left in the middle of the 0.28mm space thickness for vacuum (also other thickness). Because the negative pressure is formed between the two sheets of glass during vacuuming, the two sheets of glass are sucked together and the vacuum layer is lost.
In terms of sound insulation performance, vacuum glass is also better than insulating glass. This is because the air inside the insulating glass is the same as the outside world, while the vacuum glass is almost vacuum, and the vacuum cannot transmit noise. Therefore, the insulating glass is better than the vacuum glass. It is also incomparable in terms of sound insulation
3. Laminated glass is a safety glass production process. It is also known as laminated glass in foreign countries. It can be two layers laminated or laminated together.
Although laminated glass has good soundproofing effect, it is still lacking, but it can achieve quite good soundproofing effect after adjustment of the intermediate film components and professional technical treatment.

Advantage:
1. Energy-saving
It can be used together with temperature controller to form infrared radiant heating system. According to the temperature needs of the user, the temperature in each room can be freely adjusted. When the indoor temperature reaches the preset temperature, the heating system will automatically stop and the heat accumulator begins to emit heat so as to maintain the preset temperature for a long time, saving energy and power.
2. Environmenal protection
Its energy is electricity so that is very evironmental.
3. Safety and comfortable
It won't explode or emit odor, wind or noist.
4. Long life expectancy
It can be used more than 20 years.
5. Health care
The heat radiant can change body microcirculation, cell organization under skin producing resonance, clearing the barrier of microcirculation, adjusting and balancing nervous system promoting metabolism, increasing body physical power. It is very good for your health.
