Function and characteristics of bentonite waterproof blanket, overview of bentonite waterproof blanket

Bentonite waterproof blanket inside the name of the bentonite is montmorillonite, mainly the use of natural bentonite, this bentonite characteristics. It expands with water. Bentonite is divided into two chemical components, sodium base and calcium base. Calcium-based bentonite can only reach three times its own volume when it expands, while sodium bentonite. It can expand by more than ten times.

And bentonite waterproof blanket features. It is very dense, which is also because bentonite can form a cross-sectional film with relatively high density under pressure, so the water permeability and compactness are very good, and the self-water retention performance is also relatively strong. And bentonite waterproof blanket used. It is a sodium-based bentonite, because it is a natural inorganic material, it will not be corroded after a long time, so it has a long life and its waterproof performance is relatively durable.

Bentonite waterproof blanket and other types of waterproof materials compared to construction. It is relatively simple, generally speaking, it does not need to be heated or pasted, as long as it is fixed with nails and washers. There you go. And there is no need for special inspection after construction, and if there are waterproof defects due to any problems, it is also easier to maintain, so the time used in construction is relatively less.

Bentonite blankets have another advantage. It is easy to repair, if there is damage in the middle, you only need to sprinkle some bentonite on the damage can be, and the lap is also, directly sprinkle bentonite on the lap. Agreed.

Bentonite waterproof blanket has strong functions of expanding and repairing cracks, and is an ideal underground-I layer leakproof material. Bentonite waterproof blanket is made by knitting sodium bentonite and high strength geotextile together. When the free expansion is limited, the sodium bentonite expands with water to form an impervious layer. After the material is installed, the bentonite can repair itself even when it encounters sharp objects. In addition, bentonite can heal and fill concrete cracks and shrinkage cracks caused by uneven settlement. It is mainly applied to basement floor, structural wall, downpass, subway station, underground continuous well, maintenance pile steel sheet pile, etc.

Sodium bentonite waterproof blanket is a new type of ecological waterproof coil, which has been widely used in water conservancy, transportation, railway, civil aviation and other civil engineering because of its anti-leakage performance. It is mainly used for the foundation treatment and capping of landfill, the seepage prevention of artificial lakes, reservoirs, channels, rivers, roof gardens, and the seepage prevention of underground buildings such as basements, subways, tunnels and underground passages.
