Automatic production of bentonite composite waterproof mat in Langfang, Hebei Province

Bentonite composite waterproof mat Bentonite composite waterproof blanket Construction of bentonite waterproof blanket: 1. Foundation requirements for artificial lakes, compacting the foundation soil layer (density %) to avoid damage caused by foundation sinking during use, which will bring permanent use Disadvantages.
The foundation soil layer should be flat and should be free of sharp objects such as stones to avoid being punctured and affecting the waterproofing effect. If the flatness does not meet the requirements, it is recommended to make a thick medium sand or thick cement mortar leveling layer.
, can be constructed in humid environment but should avoid immersion in water.
If the bottom elevation of the foundation soil layer is lower than the groundwater level, effective precipitation measures should be taken to drain away the accumulated water.
2. Laying
Overlap along the direction of water flow, that is, the upstream ones overlap on the downstream ones.
The overlap should be smooth and long.
Sprinkle ../ bentonite powder evenly on the overlap.
Considering the subsidence deformation of the foundation, if necessary, you can wrinkle the bottom with a length of ~.
The non-woven geotextile is laid on the white surface and then covered with thick tamped clay, medium sand or thick plain concrete. Thick cement mortar can also be used to embed pebbles with a particle size of -0. When the angle between the bottom of the slope and the waterproof slope of the slope is greater than: The anti-leakage geosynthetic materials for garage roofs, garden pools, oil depots and chemical storage yards are filled with highly expansile sodium bentonite between special composite geotextiles and non-woven fabrics. The upper layer of non-woven fibers passes through a special The acupuncture method makes the bentonite particles unable to flow in one direction form a uniform and high-density colloidal waterproof layer in the pad when exposed to water, effectively preventing leakage.
It is an anti-seepage lining between (on-site thick compacted clay anti-seepage lining) and polymer material geomembrane. It is mainly used in environmental engineering, waste landfills, underground reservoirs, underground infrastructure construction and other projects to solve the sealing and isolation problems. It has good anti-leakage effect and strong resistance to damage.
Two Principles
The mineral name of bentonite is montmorillonite. The chemical composition of natural bentonite is sodium-based. Bentonite has the characteristic of swelling when exposed to water. Generally, when calcium-based bentonite swells, its expansion is only about .times of its own volume. It can absorb water that is times its own weight. The high-density colloid formed by the expanded bentonite has the function of repelling water. Taking advantage of this property, people use sodium bentonite to make waterproof materials. In order to facilitate construction and transportation, the bentonite is locked between two layers of geosynthetic materials to protect and reinforce the geosynthetic geosynthetic material, so that it has a certain overall shear strength.
Tribentonite
Dense sodium bentonite forms a high-density diaphragm membrane under water pressure. Its water permeability is up to Water retention properties.
Permanent waterproof performance: Because sodium bentonite is a natural inorganic material, it will not age or corrode even after a long time or the surrounding environment changes. Therefore, the waterproof performance is long-lasting.
Simple construction and short construction period: Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Only bentonite powder and nail washers, etc. are needed to connect and secure. No special inspection is required after construction and it is easy to repair if waterproofing defects are found. It has the shortest construction period among existing waterproof materials.
Not affected by temperature: it will not break brittlely in cold climate conditions.
Integration of waterproof materials and objects: Sodium bentonite has a 1-fold expansion capacity when reacting with water. Even if the concrete structure vibrates and settles, the bentonite inside can repair cracks on the concrete surface.
Green and environmentally friendly: Bentonite is a natural inorganic material, non-toxic and harmless to humans, has no special impact on the environment and has good environmental performance.
