Do you know the purpose of Cellular Glass?

Dec. 07, 2019

Cellular Glass used in building insulation is more than 99% of the chemical composition of inorganic glass. Experience has shown that cellular glass is durable, excellent in performance and quality, and has fire resistance, water resistance, corrosion resistance, mothproof, non-toxic, non-aging, strength It is an environment-friendly material with high dimensional stability and good dimensional stability. It is not only suitable for the insulation of building exterior walls and basements, but also for roof insulation.

1. Acoustic material

Foam Glass环球直播 is mainly used as a sound absorbing material. Sound-absorbing foam glass can be pasted on a concrete substrate with cement mortar, or masonry as a large-section ventilation muffler, or pasted on a steel substrate with an adhesive. Due to its excellent characteristics, it can be used for a long time under humid and vibration conditions. However, some experts in the industry through experiments believe that the average sound absorption coefficient of ordinary foam glass is about 0.4, which can not meet the requirements of noise control for sound absorption performance. For example, China's "Code for Design of Acoustic Design of Road Sound Barriers" requires that the average sound absorption coefficient of road sound barriers be greater than 0.5. They adjusted the formula of the mixture, improved the firing process and processing method, and increased the connected porosity of the foam glass from about 60% to about 80%. Its average sound absorption coefficient is greater than 0.6, which is a high-efficiency sound absorption. material.

At present, there is no report on the use of foam glass panels as light-weight filling materials in municipal construction in China. In Japan, however, researchers have studied this and successfully applied it to municipal engineering.

环球直播Using foam glass as a lightweight filling material has the following advantages: (1) The main chemical composition of foam glass is inorganic glass, which has good heat resistance and chemical resistance. (2) Foam glass does not release harmful substances, does not pollute the foundation and underground, and is an environmentally friendly material. (3) The apparent density of foam glass can be controlled by production process parameters to adapt to different foundation conditions. (4) The closed-cell foam glass pores are closed and do not communicate with the outside world, and their quality will not change due to rain and water absorption. (5) The shape and size of granular foam glass are similar to ordinary pebbles and crushed stones. Therefore, the landfill method is similar to ordinary ground materials, and no special construction machinery is required.

It is one of the important issues for the construction industry to improve the thermal insulation performance of various building envelopes while maintaining the same thickness of the surrounding walls. And reducing the average apparent density of lightweight concrete to 700-900 kg / m3 is considered to be the most effective way to improve the thermal insulation performance of the outer envelope structure. Foam glass was first reported in France as a lightweight concrete aggregate. In the 1930s, foam glass produced by the French company St. Gubain was mainly used as lightweight aggregate for concrete due to its large pore diameter and uneven distribution. Many countries have subsequently carried out related research. We are China Cellular Glass Factory环球直播, welcome to consult.
