Using Melamine Foam to Stop Fire Tragedy like Brazil Night Club fire

April 23rd, 2013

It was so regretful to hear Brazil Night Club fire tragedy. According to economist that the death toll from a fire that broke out in the early hours of January 27th in a Brazilian nightclub has already reached 232, with more than 100 injured, many severely. Almost all the victims were young; the nightclub, Kiss, in the university town of Santa Maria in the far southern Brazilian state of Rio Grande do Sul, was popular with students. Most of the deaths were from smoke inhalation and asphyxiation.

Questions are being asked about the quality of the nightclub building and whether emergency procedures were followed. The blaze appears to have been started by a pyrotechnic flare lit on stage by a member of the band; sound-proofing material caught fire, producing toxic gases which quickly overpowered many in the crowd. Police said that at least one exit was blocked. Television stations broadcast images of firefighters, helped by bystanders, breaking through a wall to get in. Some of the victims were found in the bathrooms, possibly because they mistook them for emergency exits, and were then unable to come back out through the panicked crowds.

The real murderer, however, I think it was the sound-proofing material, PU FOAM, (polyurethane foam). Even some PU foam, which adds fire-proofing agent when producing, they were easily lit and then released toxic gases when they exposed to any outside flame.

It is the real murderer of this tragedy, if we want to stop such fire tragedy, we should stop using fire-spreading materials PU-FOAM as construction materials.

Why not try melamine foam, now, through it will cost higher, comparing with PU foam, but which is more important for you, living or money?

But why does melamine foam win other sound-proofing and fire-retardancy materials?

The reason is simple, for melamine foam is able to provide lightweight, sound-proofing and fire-retardancy properties, especially the flame-retardancy performance.

Melamine foam is a kind of soft, thermosetting and environmental protection material made from melamine resin by foaming. It has three-dimensional grid structure and 99% opening rate.

Sound Pressure Level Data (SPL)

July 16th, 2012

http://www.sinoyqx.com/blog/wp-content/uploads/2012/07/sound-pressue-diagram.jpg

Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level. The commonly used “zero” reference sound pressure in air is 20 µPa RMS, which is usually considered the threshold of human hearing (at 1 kHz).

The following table presents noise data at octave-band center frequencied for familiar residential, outdoor transportation and building activity noise sources.

Intermittent or peak noises may exceed the data given in the table by 5 decibels or more, depending on the source or environment. For many practical problems, however, the data can be considered to be typical source levels at the given distance and condition, or average general activity levels for interiors. The data can be used for design purposes if proper consideration is given to especially loud equipment or sources, which may exceed it, unusual site conditions, and any other conditions that deviate from normal. For example, it is prudent to measure transportation noise at proposed building sites near highways, airports, etc., so design data will represent existing noise sources and reflect specific site features. Note also that modern aircraft, trucks and office equipment may not be as loud as the examples in the table.

Note: Sources for noise level data include Journal of the Acoustical Society of America, Sound and Vibration, Noise Control Engineering Journal and technical publications of the U.S. Environmental Protection Agency and the U.S. National Bureau of Standards.

Melamine Foam Properties

May 12th, 2012

Melamine foam is foaming from melamine resin; therefore, melamine resin foam sees some featured properties.

Melamine foam provides excellent flame resistance, without the addition of flame retardants;

Melamine foam is used in extreme temperature ranging from -180℃ to 200℃, and even 240℃.

Melamine foam resin foam provides abrasiveness.

While, melamine resin foam has three-dimensional grid structure with 99% opening rate, consequently, melamine foam provides bellowing properties.

Melamine foam provides the one of the lowest foam in the world, 4-10KG per M³.

Melamine foam provide very good thermal insulation and high sound absorption capacity

Melamine foam sees low-temperature flexibility.
