Melamine foam, also known as melamine foam or melamine-melamine foam, is a new type of sound absorbing, heat-insulating, and heat-insulating material developed internationally in the 1990s. In addition to its excellent sound absorption, heat insulation, and fire-retardant properties, melamine foam has advantages over flame retardant, environmental protection, hygiene, and safety in comparison with glass wool and polyurethane foam equivalents.
First, melamine foam applied to vehicle construction
Melamine foams can ideally meet the growing need for sound insulation in vehicle manufacturing. Melamine foams are contoured fittings made of felt, fibers, foils and plastics that can be used as sound insulation or mufflers.
Second, melamine foam applied in the automotive industry
In addition to its outstanding acoustical engineering properties, melamine foam has high heat resistance, high fire safety, good anti-fog and chemical resistance, and low weight of the product, all of which are of high value in the automotive industry. Thus, melamine foam has reliably met the requirements for maximum flame propagation speed in all fire tests conducted to date.
The laminated sound-absorbing unit is suitable for being installed under the hood of the automobile, and also can be used as a cover in front of the body's end wall and in the transmission lane. Since these parts provided with the core material of melamine foam can withstand relatively high bending stress, fasteners can be saved compared to other sound absorbing materials.
Due to the combination of superior properties, melamine foams are also used in engine compartment silencing. In addition, melamine sponges have other uses in the automotive industry, such as composite insulation boards made of melamine foam combined with aluminum foil and visors made of melamine foam inserts.
Due to its elasticity ("memory effect"), low weight and excellent acoustic properties, melamine foams are also used in the automotive industry to fill cavities.
The acoustic properties of inserts made with melamine foam reduce the level of noise in truck cabs and agricultural machinery. Therefore, such inserts make an important contribution to protecting the health of operators and improving road safety.
Three, melamine foam applied to rail vehicles
The melamine foam has excellent acoustic properties, safety in fire protection, and light weight in rail vehicle applications, which is destined to be applied to back wall and ceiling systems as well as specially designed interior trim.
Melamine foams In the application of walls and ceilings, the strong thermal insulation due to low thermal conductivity is another major advantage. As a result, the operating costs of air-conditioned buses and the like can be significantly reduced.
Due to the lighter weight of melamine foam compared to other materials, it can also increase energy efficiency in transportation services. In addition, the weight of the wall and the ceiling area is reduced, so that the center of gravity of the vehicle moves down, and thus the safety of the curve is improved. Melamine foam is particularly important for narrow-gauge railways in the application of walls and ceilings.
Fourth, melamine foam applied to aerospace applications
The low density of melamine foam and its sound absorption capability also allow it to be applied systematically to the aerospace industry. Therefore, an acoustic material using a metal foil covered with an outer melamine foam can be used as a cladding for the launch vehicle's payload area. These materials can reduce acoustic pressure and therefore can protect some highly sensitive objects such as satellites during transit.
V. Melamine foam applied to factory buildings and building insulation projects
After the melamine foam material is cut by a profile cutter, it can be used as pipe insulation. Its high temperature resistance and flame retardance also enable it to meet the requirements of some technically demanding insulation projects.
In addition, melamine foam can also be applied to the protection of hot water tanks and equipment in the application of walls and ceilings. Based on the softness of the melamine foam, it provides a sophisticated system solution that allows the complete application of insulating materials throughout the wall. This reduces the familiar chimney effect of conventional half-shell insulation, reduces energy losses, and simplifies assembly operations.
In addition to providing thermal insulation, it also reduces the noise level.
Six, melamine foam applied to air conditioning
Excellent sound absorption and reliable fire protection characteristics are extremely important advantages of melamine foam, so that it can be used as an impeller sound insulation material in air conditioning equipment and ventilation equipment.
The inner wall of the fan cover is lined with melamine foam to reduce noise levels. Its low thermal conductivity and high long-term operating temperature are key factors that enable it to be used in solar collectors.
Seven, melamine foam applied to acoustic test room or recording studio
The high sound absorption and fire safety of melamine foam make it suitable for acoustic tests such as low-reflection test chambers, engine test stands, wind tunnels and recording studios.
Eight, melamine foam applied to the field of cleaning
The application of melamine foam in the field of cleaning can be said to be a new application of melamine foam. It adopts the mechanism of physical decontamination and relies on the nano-capillary opening structure in the sponge to automatically adsorb the stains on the surface of the object during the wiping process. It does not rely on any chemical detergent to help it degrade. Due to its special decontamination mechanism, it makes stubborn stains that cannot be wiped off by many conventional cleaning sponges, and has a magical cleaning effect on stubborn and uneven surfaces. It is the most ideal replacement for traditional cleaning methods. The high-density nano-sponge made by special processing and deep processing again improves its product density and physical properties, making its density twice that of similar products, and therefore has better toughness, and can directly knead dry moisture and has strong wear resistance. The effect is more pronounced.
