1、Product introduction
Bentonite waterproof blanket is a composite material with excellent waterproof properties. It is usually composed of high-quality bentonite and polymer materials. It is a perfect landfill liner material geosythetic caly liner. The bentonite waterproof blanket product introduction is as follows:
（1）Material composition and characteristics: Bentonite waterproof blanket is made of bentonite and polymer materials using a special process. Bentonite clay is highly absorbent and expands to form a uniform, waterproof layer when exposed to moisture, while the polymer material provides additional durability and strength.
（2）Waterproof performance: This waterproof blanket can effectively block moisture penetration and provide reliable waterproof protection. When exposed to water, bentonite's water-absorbing properties form a dense waterproof layer, effectively preventing moisture from entering a building or structure.
（3） Application scenarios: Bentonite waterproof blankets are widely used in underground structures, foundation pit waterproofing, river embankments, sewage treatment and other fields. Its excellent waterproof properties make it an essential waterproof material in various construction projects.
（4）Durability and reliability: This waterproof blanket has strong weather resistance and corrosion resistance, and can maintain waterproof effect for a long time. Its stable waterproof performance and reliability make it perform well in a variety of environmental conditions.
（5） Installation and maintenance: During installation, ensure that the base layer is clean and flat, and then lay the waterproof blanket neatly and secure it. In terms of maintenance, regular inspection and keeping clean will help extend the service life.
（6）Price and delivery cycle: Product prices vary depending on specifications and order volume. Delivery cycle depends on order volume and production capacity. We will do our best to meet your needs.
Bentonite waterproof blanket has become an indispensable high-quality waterproof material in construction projects due to its excellent waterproof performance and wide range of application fields.
Sodium bentonite waterproof blanket production equipment
2、How is sodium bentonite waterproof blanket produced?
Production Process:
Specific operating procedures:
(1) Prepare the woven fabric and non-woven fabric in advance, put them in your position, and let the woven fabric and non-woven fabric two layers pass through the acupuncture part;
(2) Prepare the bentonite to the feed bucket, and transport the bentonite to the horizontal conveyor by the angled cage to control the feeding speed;
(3) The bentonite flow rate is adjusted by adjusting the position of the lower plate and cylinder;
(4) The needling machine thrusting and pulling the three through the hook barbed needle at a high speed to become a body intertwined with each other, in which the spindle and the net roller linkage drive, the barbed waterproof blanket transported to the next process;
(5) Cut the GCL waterproof blanket vertically and horizontally and roll it, adjust the meter to make it reach the length and automatically cross cut and check the package.
2、Bentonite waterproof blanket Physical properties:
Comparison of the national standard of physical and mechanical properties of sodium bentonite waterproof blanket by in-needling method and by needling coating method. It conforms to the national standard JG/T 193-2006 issued by the Ministry of Construction of China.

5、Bentonite composite waterproof pad (GCL) construction precautions:
(1) The storage and transportation of bentonite composite waterproof pad (GCL) should be waterproof, moisture-proof and anti-strong sunlight exposure. During storage, the floor should be raised by overhead method, and the bentonite composite waterproof pad (GCL) transported to the site should be used up on the same day.
(3) During the construction of the next process or adjacent works, the bentonite composite waterproof pad (GCL) of the completed process should be properly protected, and there should be no man-made damage.
(3) Try to avoid wearing spikes and high heels on the bentonite composite waterproof mat (GCL); Vehicles and other machinery shall not be rolled bentonite composite waterproof pad (GCL).
(4) In the construction of GM/GCL composite liner, the completed GCL should complete the construction of HDPE film or lay 300mm thick clay protective layer on the same day, can not complete the construction of HDPE film or clay protective layer on the same day, should be covered by GCL, to prevent rain and snow and make GCL hydration and strong sunlight on GCL explosion.
(5) For the anti-seepage and waterproof construction works of GCL single-layer liner, after the completion of construction and acceptance, it should be quickly backfilled with soil, sand or stone particles with a specific gravity greater than 2.0. In order to prevent damage to GCL, the backfill soil should not contain gravel with a particle size greater than 10mm, and the thickness of the backfill soil should not be less than 30cm. Backfill soil should be graded backfill compaction, compaction degree can not be less than 85%.
