3D sandwich composites are ideal core material for double-wall
tanks. The space between two decklayers enables the installation of monitoring
devices which can effectively detect the leakage of liquid inside the
tanks.
The internal liner in
reinforced 3D glass fiber material can be perfused with liquid, evacuated and embedded monitoring
probe, sensors, wire etc components. The reinforced 3D glass fiber material used as interlinings of storage tanks (the thickness of middle
layer from 2 -10 mm all can be designed.) can effectively monitored the leakage
and use situation of liquid in storage tank, have solved the issue of rapidly
detect leak in the USTs,and effectively prevent the air, soil and groundwater from
pollution. So it is a kind of new functional and environmental products.
