The foam aluminium sheet is casted pressure by the aluminium alloy.It can be recycled after destroy or update.It is the only green product can't be secondary pollution to the enviroment at present.The foam aluminium sheet is the frontier and replace product of the non-fibroid absorbing material,it is not the same as the glass fibre,mineral wool,rock wool etc on the road through sun-scorched and rain-drenched to be ageing,the dust flyoff leads to the secondary pollution to atmospheric environment.
It has stable soumd absorption performance,the average sound absorption coefficient>=0.6,especially it rains or collects dust,the sound absorption coefficient will not be changed.It fits the requirement of acoustics.Meanwhile it has good sound insulatuin performance,the acoustical reduction coefficiet>24db(A),it fits the requirement of sound insulatuin.
The foamed aluminium board select and use the advanced outdoorspaint through more than once absorbing and spurting.The stoving technological process solves the problem as the colour fade when to be exposed and beaten from wind and sunshine.
It has the same fireproofing noninflammability,weather fastness,stain resistance,ageing resestance,it can bear blowing,raining,sunshining.
It has definite resisting compression,impacting performance,there’s no fixed fastening connection between the barrier and upright.And add the safety rope to prevent falling.So when the barrier bears the unexpected striking,it can make the barrier home and dry.
The product is standardization,symbol,serialization and uses the combimation parts to insert and install,sping tight structure.So fixing is convenient and safe.Meanwhile also fully lien the interval for exoansion and contraction.
