Heat insulating &sound -absorbing foam glass - many

Foam glass is a finely ground glass powder as the main raw materials, by adding a foaming agent after melt foaming and annealing cooling processing handling, manufactured with uniform independent aperture closing(opening) air gap structure of new inorganic materials. Since these new materials have moisture-proof, fire-proof, and anticorrosion functions, Combined with the glass materials with long-term use without deterioration of characteristics, and used in such harsh environments as thermal insulation, deep cooling, underground, open air, flammability, humidity, chemical corrosion and etc. so the users are greatly favored with it.

Foam glass wall plate insulating layer compared to other thermal insulation materials

Heat-insulating foam glass applied to deep cooling low cooling, refrigeration equipment and pipeline installation.

Sound-absorbing materials: Sound-absorbing foam glass absorption coefficient of the low-frequency (120 -125Hz) is 0.35-0.45.But high frequency sound absorption coefficient is above 0.5, 125-1600 Hz average absorption coefficient is above 0.58, incombustibility, good thermal stability, odorless, non-toxic .Available for various types of Silencers for ventilation, indoor acoustics and noise control, factory noise source workshop control Office, can also be used foam glass wall of sound-absorbing materials to reduce interior noise the sound pressure level.

Sound-absorbing foam glass is aperture-opening structure, unlike thermal insulation foam glass as sealed porosity. Sound-absorbing decorative foam glass mostly made of light-color. Neutral foaming agents, such as carbonates, nitrates, alkali, etc. are generally used in the production process, so that products do not stain when in the foamed. Alternative blowing agents and colorants, foam glass that can be made with various colors, like black, gray, purple, green, and blue, and so on. The sound absorbing decorative foam glass is generally made of a plate shape, the maximum size 600mm x 600mm, thickness of 20mm-300mm.

The characteristics of foam glass is non-flammable and can be used in a wide temperature range and excellent resistance to chemical corrosion, without putrefaction, airtight, no moisture, long-term use of the same performance, good mechanical strength, easy to process ,and free from rats gnawing.

PIR

PIR, English full name: Poly isocyanurate foam, abbreviated by PIR, and also called Poly isocyanurate, is a new type of thermal insulation materials for deep cooling, can be used from-196 ° c ~120 ° c range of all kinds of pipes and equipments, as well as the demand for thermal insulation of the building. For the development and application of PIR material in China , ensuring the technical basis for perfect compliance with existing GB system. PIR is the foamed material, after exposure to isocyanates catalysts, which react with polyether. Its physics and fire proof performances are more excellent than ordinary polyurethane. It is an ideal organic low-temperature insulation material. Small heat conductivity factor, and lightweight shock-proof and high adaptability. Widely used in refineries, chemical plants, ethylene, fertilizer, cold storage, and the architecture industry insulation.

1 Thermal conductivity performance is excellent and it is the head among all the organic cold protection materials.

2 Fire -proof performance conforms to the standard of GBB 624 flame retardant B1-level, American ASTM E 84.

3 Used in ultra-low temperature environments with high compressive strength, low thermal conductivity, excellent dimensional stability, and other outstanding performances

4 Cut molding will be able to meet the composite multilayer structure design requirements of all kinds of thickness to ensure installation quality
