Do you know bentonite waterproof blanket? This is a very common material. Bentonite waterproof blanket, also known as bentonite composite bentonite waterproof blanket, is a new type of geosynthetic material. This synthetic material has a wide range of applications, and bentonite waterproof blanket can be seen in any industry. Many people don't pay attention to bentonite waterproof blanket, so they don't know much about its use, but in fact, it is probably very necessary to understand the application field of bentonite waterproof blanket. The following small topic will introduce the application of bentonite waterproof blanket in some aspects in detail.

What are the main application fields of bentonite waterproof blanket?

Bentonite waterproof blanket GCL is mainly used to prevent penetration or seal in civil engineering, water conservancy engineering, and environmental protection engineering. For example, anti-seepage design of channels, reservoirs, dams, dump floor floors, containment site seals can be used alone or with clay liners or earthwork membranes. Bentonite waterproof blanket GCL is competitive in the schemes that can use clay, asphalt, concrete, geomembrane and GCL as the sealing layer.

Bentonite waterproof blanket products are mainly used in the following fields:

1. Municipal engineering, subway, underground engineering of buildings and seepage prevention of roof reservoirs.

2. Environmental sanitation, domestic waste landfill, sewage treatment new cloud field, industrial waste.

3. Discuss water conservancy, anti-seepage, residual blockage and reinforcement of rivers, lakes, reservoirs and dams.

4. Leakage control in gardens, artificial lakes, golf courses, ponds, etc.

5. Anti-seepage, anti-corrosion, anti-seepage and reinforcement of projects in petrochemical, mining, agricultural and other fields.

The name of the bentonite in the bentonite waterproof blanket is montmorillonite, and the natural bentonite is mainly used. The characteristic of this bentonite is that it will expand when it meets water. Bentonite is divided into two chemical components, sodium and calcium bases. Calcium bentonite can expand three times its own volume, and sodium bentonite can expand more than 10 times.

Among the characteristics of bentonite waterproof blanket, it is very tight. This is because bentonite can form a high-density diaphragm under pressure, with good pitch and density, and relatively strong self-healing performance. Use sodium bentonite. Because it is a natural weapon material, it will not deteriorate over a long period of time, so it has a long life and waterproof performance for a long time.

If you compare waterproof blankets with other types of waterproof materials, the construction will be relatively simple. Generally, there is no heating or pasting, and only nails and washers are used to fix the connection. In addition, special inspection may not be carried out after construction. No matter what the problem is that causes waterproofing defects, repairs are easy, so construction takes very little time.

Another advantage of waterproof blankets is easy maintenance. If there is damage in the middle, just spray a little bentonite, put it on the damaged place, and if there is an overlap, spray bentonite directly on the overlap.
