As a China Foam Glass Manufacturer环球直播, there is some information about foam glass to share with you.
环球直播Building roof insulation
There are three main types of foam glass used for building roof insulation: upright flat roof, inverted flat roof, and slope roof. Among these structures, the foam glass is easily combined with other inorganic materials, and the construction is easy, and the waterproof, fireproof, and heat insulating effects are better. Inverted roofing can also be used for greening.
Foam Glass JC/T647
Building exterior insulation
As an external thermal insulation material for exterior walls, Foam Glass JC/T647环球直播 can effectively reduce the thickness of the wall, reduce the quality of the building structure and expand the use area. Experts from Beijing University of Technology Tian Yingliang and other experts studied the specific application of foam glass in building energy conservation. It is believed that different areas should be calculated according to the heat transfer coefficient requirements.
Sound absorbing material
Open cell foam glass is mainly used as a sound absorbing material. The sound absorbing foam glass can be glued to the concrete base with cement mortar, or built into a large cross section ventilation muffler, or pasted on a steel substrate with New White Mastic. Due to its excellent properties, it can be used for a long time under humid and vibration conditions. However, some experts in the industry have experimented and concluded that the average sound absorption coefficient of ordinary foam glass is about 0.4, which still cannot meet the requirements of noise control for sound absorption performance. 5。 The average sound absorption coefficient of the sound absorption coefficient of the road sound barrier is greater than 0.5. By adjusting the formulation of the mixture, the roasting process and the processing method are improved, and the connected porosity of the foam glass is increased from about 60% to about 80%, and the average sound absorption coefficient is greater than 0.6. material.
环球直播At present, there is no report on the application of foam glass as a lightweight filler material in municipal construction in China. However, in Japan, researchers have studied this and successfully applied it to municipal engineering.
环球直播Foam glass is used as a lightweight filler material, which has the following advantages: (1) The main chemical component of foam glass is inorganic glass, which has good heat resistance and chemical corrosion resistance. (2) Foam glass does not release harmful substances and does not pollute the foundation and groundwater. It 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) Closed-cell foam glass pores are closed and are not connected to the outside world, and their quality will not change due to rain and water absorption. (5) The shape and size of the granulated foam glass are similar to those of ordinary pebbles and gravel. Therefore, the landfill method is similar to that of ordinary foundation materials, and no special construction machinery is required.
