Sodium Bentonite Geosynthetic Clay Liner For Water Conservancy And
Garden Applications
Product Introduction
Sodium bentonite waterproof blanket is a new type of environmental
protection and ecological composite impermeable material, which has
been widely used in many fields because of its unique anti-seepage
performance.
Product Properties
The main raw material for the sodium-bentonite waterproof blanket
is sodium-bentonite, which is known in mineralogy as
montmorillonite and can expand more than 24 times when exposed to
water. This property enables the sodium-bentonite waterproof
blanket to form a uniform colloidal system with high viscosity and
low filtration. In addition, the material also has excellent
waterproof and impermeable properties. Since bentonite is a natural
inorganic material, it does not occur aging reaction, so it has
good durability, and is harmless to the environment, and belongs to
environmental protection materials.
Product Application
1. Municipal works: including subways, underground works of
buildings and seepage prevention of roof reservoirs.
2. Environmental protection and sanitation: suitable for the
treatment of domestic waste landfills, sewage treatment sites and
industrial waste.
3. Water conservancy: It can be used for seepage prevention,
leakage blocking and reinforcement of rivers, lakes and reservoirs.
4. Garden: artificial lake, golf course pond seepage prevention,
etc.
5. Petrochemical, mining, agriculture and other fields: used for
engineering seepage prevention, corrosion prevention, leak
prevention and reinforcement.
