The characteristics of melamine sponge material and its application in various fields
Melamine material is one of the most widely used polymer materials in the world. It has the advantages of good heat insulation, insulation, high specific strength, oil resistance, cold resistance, moisture resistance and dimensional stability, and has become a popular choice for refrigeration, shockproof, and gaskets. , an indispensable material for thermal insulation. Melamine sponge material produced by sponge is used for sound absorption, heat insulation, heat preservation and fire protection. In addition to excellent sound absorption and heat insulation properties, it has the advantages of high flame retardancy, environmental protection, and hygiene.
Melamine sponge has no residual free formaldehyde, is chemically stable, and can meet food-grade hygiene requirements (its raw materials can be used to make tableware). In addition, without adding any flame retardant, the flame retardant performance can reach the B1 level specified in Germany’s DIN 4102 and the United States’ UL94-V0 level standard. It is a common sponge plastic, such as polyolefin, polystyrene, polyurethane, etc. When exposed to fire, melamine sponge ignites slightly and forms char, which is self-extinguishing from the fire. When the surface layer is slightly ignited, nitrogen and carbon dioxide are released, which is fire-extinguishing, does not produce toxic smoke, and will not drip, thus greatly reducing the incidence of fire accidents. At present, melamine sponge is widely used in high-tech fields such as aviation, aerospace, military, electronics, vehicles, trains, ships and other vehicles, terminals, theaters, stadiums, etc. Recording studio and city. Fast roads and high noise working conditions, suitable for all aspects of the civil field, such as general home decoration, household appliances and daily cleaning products. It is a new type of environmentally friendly material with great development prospects in the 21st century.
Melamine sponge in the field of railway transportation
Melamine sponge in the field of railway transportation , as far as rail vehicles are concerned, the excellent acoustic and fire-resistant properties of melamine sponge are destined to play a role in wall and roof supports as well as decorative interiors in laminates. In the case of side wall and ceiling applications, the low thermal conductivity of melamine sponge exhibits effective thermal insulation properties and can therefore significantly reduce the operating costs of air-conditioned buses. Because melamine foam is lighter than other insulation materials, it also plays an important role in improving energy efficiency in the transportation services industry. In addition, the weight reduction of the vehicle walls and the vehicle’s top position result in a reduction in the vehicle’s load-bearing capacity, thereby increasing the vehicle’s stability when passing through curved roads, which is especially important on narrow tracks. Melamine sponge can be combined with composite cloth, PU board and other materials. It is used in the rail transportation industry, such as high-speed rail, light rail and subway. Melamine sponge can be used in equipment compartments, air ducts, doors, car interior walls, roofs, seats, side wall insulation, floors and engine surrounds. Light weight and low performance reduce the weight of the entire vehicle, improve cornering stability and reduce energy consumption. Currently, CSR Group uses melamine sponge as sound insulation material. Melamine sponge has outstanding sound insulation effect, its B1 flame retardant performance, does not add any flame retardants, and meets the flame retardant standards of automobile parts.
Melamine sponge is used in the field of equipment air conditioning
Excellent sound absorption and fire protection Performance is an important advantage of melamine sponge, which can be used for cooling air conditioning equipment. Melamine sponge can also be installed on the inner wall of the fan cover to reduce noise levels, and its low thermal conductivity and high temperature resistance can play an important role.
Melamine sponge is used in the field of industrial insulation
People have increasingly higher requirements for the flame retardancy of thermal insulation materials, so traditional thermal insulation materials must be added Flame retardants that are harmful to humans and not durable. However, flame-retardant glass wool and rock wool will produce a large amount of fine powder during installation and use, which can cause discomfort to the human body. Melamine sponge is high temperature resistant, flame retardant (B1 flame retardant), and easy to process, surpassing traditional insulation materials such as glass wool, rock wool, polystyrene, and polyurethane sponge. By mechanically cutting it into shape, it can be processed into insulation material for pipe protection. Control energy losses, simplify maintenance and reduce noise levels while providing insulation. It can withstand high temperatures (long-term operating temperature is about 150°C, short-term peak temperature can reach 240°C); low-temperature resistance capacity (long-term operating temperature is about -150°C, short-term peak temperature can reach -200°C) and flame retardant properties, making it suitable for more technically demanding jobs.
Melamine sponge is used in industrial noise reduction fields
Industrial and manufacturing environments High decibel noise in the air not only reduces productivity, but also threatens workers’ health. Research�Shows that exposure to high noise can cause stress and fatigue, which can lead to work-related injuries or hearing loss. Work environments subject to high levels of noise, such as heavy construction machinery work noise and metal processing plants and other confusing human sounds, can reduce noise to acceptable levels by using melamine sound-absorbing sponges.
Melamine sponge wall panels and refractor panels can reduce and control noise in factories, assembly plants and other industrial applications by blocking and filtering sound waves and reverb. After cutting, the melamine sponge board can be directly used for sound absorption on factory ceilings and walls. After special-shaped cutting, it can be processed into pipe insulation layer, which has excellent noise reduction and heat insulation effect on hot water tanks, air conditioning ventilation ducts, gas pipes and hot air ducts.
Melamine sponge is used in the field of aerospace navigation
Melamine sponge is made of aluminum foil or waterproof Acoustic components made of textile-covered melamine sponge are used for noise treatment in ship engine rooms. Airline manufacturers use melamine foam to fill aerospace seats. In addition to their excellent sound-absorbing and flame-retardant properties, air seats containing melamine foam are significantly lighter than traditional seats. Weight reduction and fuel cost savings bring economic and environmental benefits to airlines. Melamine sponge’s light weight and high sound absorption make it useful in the aerospace industry. Foil-covered acoustic components made of melamine sponge-processed plastic are used in the payload area of the rocket launcher. This arrangement reduces acoustic stress and therefore provides a high degree of protection for highly sensitive instruments in transport, such as satellites. Acoustic components made of melamine sponge covered with aluminum foil or waterproof non-woven fabric are used for ship engine room noise treatment. As a lightweight insulating and noise-reducing material, melamine sponge has been widely used in aviation seats, cabin interior filling, passenger ship cabins, warship engine rooms, cryogenic liquefied gas carriers and artificial satellites.
Melamine sponge is used in soilless cultivation
2g ordinary polyurethane sponge It can only absorb 60g and has a short water retention time; 2g melamine sponge can absorb 600g, which is 10 times the water absorption capacity of polyurethane sponge and has a long water retention time. Because melamine sponge has excellent water absorption and water retention properties, it has good application prospects in the field of implant base materials. As a matrix, it has strong water content (no loss of nutrient solution), anti-aging properties, stable performance, and can be soaked in nutrient solution for a long time without deformation or aging. It is widely used in greenhouse cultivation, modern agriculture, artificial breeding, vegetable planting bases, green vegetable planting and other fields.
