Description
Technical field
The invention discloses a kind of haydite track acoustic boards, belong to building material technical field.
Background technique
The fast-developing of underground railway track traffic brings many conveniences to people's trip, however, with metro construction
Quantity increase year by year, subway station noise control and underground railway track vibration damping are all increasingly becoming the topic for comparing concern.Especially
Problem of noise pollution in underground railway track, noise bring serious influence to people's lives.According to research shows that: noise can allow
The mood of people is had the fidgets, and is influenced people and is worked normally and rest, damages the physical and mental health of people.People live in noise for a long time
In the environment of pollution, the various problems such as people's hearing system, nervous system can be caused.Such as it is easy to appear hearing loss, deaf ear
The diseases such as ring, sleeping at night dreaminess, tired powerless, the memory decline of whole body, meanwhile, noise can make people's labor productivity
It reduces, seriously affects the development of economic construction.Therefore, using reasonable noise-reduction method, noise pollution in rail traffic is solved
Problem is extremely urgent.In order to solve the problem of noise pollution because of caused by the fast development of underground railway track traffic, put into a large amount of
Experience studied, take many technical measures to reduce noise pollutions in train and track structure design, but its noise reduction is imitated
Fruit is not but fairly obvious.Rail traffic acoustic board is laid with along track to reduce the noise pollution in underground railway track, passed through
Its noise reduction effect of comparative analysis is fairly obvious.Since city underground is in special subterranean tunnel environment, to applying to subway
In sound-absorbing material it is more demanding.Sound-absorbing material does not need only to have enough durable degree, waterproof, and fire resisting is corrosion-resistant, and
Sound absorption qualities meet the noise characteristic in subway, need the excellent noise reduction effect of material and have enough intensity and resist air-flow punching
The performance hit.The particular surroundings of subway can not be competent at for common sound-absorbing material, and haydite porous sound absorbing material belongs to cement
Quito hole sound-absorbing material, maintains the fundamental characteristics of cement base porous sound absorbing material, it has enough durable degree, prevents
Water, fire resisting is corrosion-resistant, and excellent noise reduction effect, and the performance with enough intensity and resistance gas shock is suitable as track friendship
The raw material of logical abatvoix.
And traditional track acoustic board the problem of can not being further increased there is also sound-absorbing effect and compression strength, therefore,
The shortcomings that sound-absorbing effect and compression strength for how improving conventional rails abatvoix can not further increase is developed in the hope of exploring
Track acoustic board with good comprehensive performance is problem to be solved.
