? Manufacturing principle of foam glass
The earliest inventor of foam glass was Corning Company in Pittsburgh, USA. It is an inorganic nonmetallic glass material made by mixing broken glass, modified additive, foaming agent and foaming accelerator, finely crushing and uniformly mixing, and then melting, foaming and annealing at high temperature. It consists of many uniform bubble structures with a diameter of 1-2mm. This new material has multiple functions such as fire prevention, moisture prevention and corrosion protection, and will not deteriorate after long-term use. This material combines many advantages and is favored by users. It is considered by users to be a kind of green thermal insulation material.
Properties of foam glass
Foam glass has good functions of heat insulation, fire prevention, moisture prevention and sound absorption. It is a light and high-strength building material and decorative material. It can be used in the temperature range of-196 degrees to 450 degrees. Although there are many other new thermal insulation materials on the market, foam glass plays an increasingly important role in various fields with its absolute advantages, such as safety, moisture-proof engineering, sound absorption and so on. Its production realizes the reuse of solid waste, protects the environment, and at the same time obtains rich benefits, which is an example worthy of learning by many enterprises.
Advantages of foam glass
1, non-combustible, low water absorption, wide application range at high temperature; Not easy to weather or age, not easy to be bitten by rats and corroded by microorganisms.
2. This material is non-toxic and harmless to human body; It is non-radioactive and will not release substances harmful to human body or environment, so it is a kind of green environmental protection material.
3. By changing the formula and foaming process flexibly, various controllable properties can be adjusted.

Foam glass is a lightweight and high-strength building material and decorative material, which has excellent heat insulation (cold preservation), sound absorption, moisture resistance and fire prevention performance. Its service temperature ranges from-196 to 450 degrees, its Class A noncombustible life is the same as that of buildings, and its moisture permeability coefficient is almost zero. Although other new thermal insulation materials emerge one after another, foam glass plays an increasingly important role in low-heat insulation, moisture-proof engineering, sound absorption and other fields because of its permanence, safety and high reliability. Its production is the reuse of waste solid materials, and it is an example of protecting the environment and obtaining rich economic benefits.
Lava foam glass: natural lava or industrial waste residue such as perlite and obsidian are used as basic raw materials, and a certain amount of glass powder can be added to reduce the foaming temperature, and mirabilite is used as foaming agent to make foam glass. Generally, it can be used as insulation materials and wall materials for buildings and industrial equipment.
superiority
1 non-toxic, non-radioactive, will not release harmful substances, will not pollute the foundation and groundwater, is an environmentally friendly material;
2, non-combustible, low hygroscopicity and water absorption, and wide use temperature range. The practical use temperature of ordinary foam glass is 240 ~ 280℃;
3, not easy to weather, not aging, not bitten by rats, insects and microbial corrosion;
4. By changing the formula and foaming process, the properties such as bulk density, open porosity and closed porosity can be adjusted;
According to the various properties of foam glass, it can be used as heat insulation material in various departments of construction engineering, as well as shipbuilding, chemical industry, low temperature and high temperature technology. White and colored glass are also used as sound-absorbing and decorative materials. The waste materials in production-foamed glass powder and broken materials can also be used as fillers for decorative lightweight concrete. According to the different uses, the foam glass products produced by the corresponding technology can be divided into four categories, namely, thermal insulation foam glass, sound-absorbing decorative foam glass, decorative foam glass and granular foam glass.
Foam glass does have many benefits and advantages. Do you have a new understanding of this new material after Bian Xiao introduced it? Do you like foam glass? The above is about the price of foam glass, I hope I can help you!
