Bentonite composite waterproof blanket is a new type of geosynthetic material. It is a blanket-like waterproof membrane made of graded natural sodium bentonite particles and corresponding additives mixed as raw materials. The bentonite particles are fixed between geotextiles and plastic woven fabrics through acupuncture technology and equipment. Bentonite waterproof blanket not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance.
According to the production process, bentonite waterproof blankets can be divided into acupuncture method sodium bentonite waterproof blankets, acupuncture coating method sodium bentonite waterproof blankets and adhesive method sodium bentonite waterproof blankets.
The needle-punched sodium bentonite waterproof blanket is a composite layer of high-density polyethylene geomembrane on the outer surface of the non-woven geotextile of the needle-punched sodium bentonite waterproof blanket.
The adhesive sodium bentonite waterproof blanket is a sodium bentonite waterproof blanket produced by bonding bentonite particles to high-density polyethylene boards with adhesive and compressing them
Physical characteristics of bentonite waterproof blanket
, has excellent waterproof and anti-seepage performance, anti-seepage hydrostatic pressure can reach up to 100%, permeability /, bentonite mass per unit area /, bentonite is a natural inorganic material, does not undergo aging reaction, has good durability and does not harm the environment It is an environmentally friendly material that will not cause any adverse effects. It has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc. It is easy to construct and is not restricted by the construction environment temperature. It can also be constructed below ℃. During construction, you only need to lay the waterproof blanket flat on the ground. When constructing on the facade or slope, fix it with nails and washers, and overlap it as required.
Easy to repair Even after the waterproofing (seepage) construction is completed, if the waterproofing layer is accidentally damaged, as long as the damaged part is simply repaired, the perfect waterproofing performance can be regained.
, the performance-price ratio is relatively high, and it has a wide range of uses.
The product width can reach meters, which matches the international geotextile (membrane) specifications, greatly improving the construction efficiency.
As a new type of environmentally friendly and ecological composite anti-seepage material, sodium bentonite waterproof blanket has been widely used in civil engineering projects such as water conservancy, environmental protection, transportation, railways, and civil aviation due to its unique anti-leakage performance. Basic treatment and capping of landfills, anti-seepage of artificial lakes, reservoirs, channels, rivers, roof gardens, and anti-seepage of underground buildings such as basements, subways, tunnels, and underground passages.
Scope of application of waterproof blanket
Suitable for municipal (garbage landfill), water conservancy, environmental protection, artificial lakes and building underground waterproofing and anti-seepage projects. It can still be constructed at negative temperatures (°C) where traditional waterproofing materials cannot be constructed on wet base layers (but no open water). It can also be constructed in rainy and snowy weather. It is not suitable for strong acid and strong alkaline solution anti-seepage due to the bentonite system. Inorganic materials, so their durability is better than organic waterproof materials
Anti-seepage principle of waterproof blanket
The mineral name of bentonite is montmorillonite. Natural bentonite is mainly divided into sodium-based and calcium-based according to its chemical composition. Categories. Bentonite has the characteristic of swelling when exposed to water. When calcium bentonite swells, it expands only about times its own volume, while sodium bentonite absorbs five times its own weight of water when exposed to water and expands to more than twice its original size. Sodium bentonite will Locked between two layers of geosynthetic materials, it plays the role of protection and reinforcement, giving it a certain overall shear strength.
