It must be more environment-friendly and advanced than present concrete
water tank with following problems :
- Bisphenol A, which is environmental hormone fatally harmful to the human
body, was detected.
- In 1~2 years of construction, the epoxy resin film swells and peels off.
- Be cautious of fire. If ventilation is poor the worker may be fatally hurt.
If the skin is stained with the paint, the paint must be removed immediately
1. What is PE ?
HDPE (High density polyethylene) is produced through high-tech manufacturing
method and its high workability and outstanding quality are acknowledged throughout
the world (Material provided by LG Chem) The product is not corroded or rusted
by chlorine gas. It is also highly chemical-resistant (acid and alkali) and
inhibits the propagation of microbes such as bacteria. Moreover, it is not eroded
at all by corrosive substances in soil.
The product uses materials that were approved to be used for drinking water
by FDA of USA and JHPC of Japan. Because it has clean surface and is highly
corrosion-resistant, it is outstandingly sanitary and clean even after a long
use.
PE and PP are highly resistant to abrasion, so they are permanent. Because of
its high elasticity coefficient, it is not damaged if not intentionally destroyed
and shows strong restoring force.
If a PE sheet is attached to the surface of concrete using fixing pins, an additional
PE sheet is installed over the fixing pins and the two sheets are thermally
bonded to each other, a perfect watertight effect is attained. PE sheet is manufactured
through special extrusion and heated forming and pressing technology, so it
is recyclable.
2. Application
PE, considering its elements, is known to be harmless to the human body and
widely used in food packages such as the containers of various drinks, water
container, baby bottles and paper cup coating, construction facilities, PE pipes
for water supply, etc.
In addition, the product does not contain additives or elements such as PVC
and FRP that may cause the occurrence of environmental hormones nor additional
reinforcing materials (glass fiber).
