Nano-sponge/melamine foam is also called melamine foam. The material itself has flame retardancy, high temperature stability and flexibility. Nano-sponge has unique properties such as sound absorption, heat insulation, flame retardancy, high temperature resistance and light weight. Widely used in the fields of architectural decoration, transportation vehicles, watercraft, aerospace, electromechanical equipment, industrial sound absorption and insulation. Xiamen Sihang is committed to gradually replacing the commonly used sound-absorbing and heat-insulating materials such as glass wool, felt, ordinary foam, polyurethane, asbestos, polystyrene and polyethylene, and has become a new sound-absorbing and heat-insulating product that has attracted much attention in the market.

     97% open porosity, completely connected by three-dimensional mesh filaments;

     Three-dimensional grid structure system → good insulation effect (λ=0.035);

     Very low density, 8.5 kg / m3 → energy saving;

     The flame retardancy of melamine itself → no need to add flame retardant to reach the B1 standard, no dripping, no toxic fumes;

     High temperature stability of melamine → long-term working temperature -180 ° C - 200 ° C;

     Chemical stability → strong alkali resistance, weak acid.

The ability of nano-sponge to withstand high temperatures (long-term operating temperature is about 150 ° C, short-term peak temperature can reach 200 ° C); withstand low temperature capacity (long-term working temperature is about -150 ° C, short-term peak temperature can reach -180 ° C) and flame retardant, making it suitable for more technically demanding work.

 Researchers have found that their low temperature stability is utilized. The nano-sponge is used to heat the steel can filled with liquid natural gas at a temperature of about -160 ° C. Other applications include insulation of hot water tanks, boilers and their equipment.

Through the shape mechanical cutting, Xiamen Sihang nano sponge can be processed into insulation layer material for pipeline protection. While providing insulation, energy losses are controlled, maintenance is simplified, and noise levels are reduced.

Nanosponge insulation

The nanosponge is elastic and stable at low temperatures; in the laboratory test, the nanofoam retains its properties at a temperature of about -200 °C. For this reason, this combination of features that can insulate a liquid natural gas tank has many advantages: this high-elasticity and heat-insulating foam is not affected by low temperatures compared to conventional foams that are brittle at the same low temperature. . It is also possible to combine nanofoam with other foams. Conventional foam breakage can be prevented by applying a layer of nanofoam on the outside of a conventional foam with unique insulation and processability to protect it from low temperature liquid gases.

Liquid natural gas is usually transported from the storage to consumers through pipelines for transportation distances up to 2,500 kilometers. If the transport distance is longer, it is usually more economical to liquefy the gas and use the shipping. Since liquid natural gas is stored at extremely low temperatures, it must be transported through containers with efficient insulation.

 Case

            1. Insulation materials for natural steam pipes, methanol, etc.;

            2. After the profiled processing, the aluminum is thin and the non-woven fabric forms a new thermal insulation material for use in the industrial field.
