1、Product introduction

Sodium bentonite composite waterproof blanket (GCL) is a new type of geosynthetic material, which can be specially used for impermeable geosynthetic materials such as artificial lake water feature, landfill, underground garage, roof garden, pool, oil depot and chemical plant. The high expansion sodium bentonite is filled between the composite plastic flat silk geotextile and non-woven fabric, and the bentonite particles can not flow unidirectional by acupuncture method, and a uniform and high density rubber waterproof layer is formed in the pad when it meets water to effectively prevent water leakage. Bentonite waterproof blanket not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance. It is a kind of impermeable lining between GCL and polymer material (geomembrane).

  The waterproof mechanism is that the sodium-based granule bentonite used in the bentonite waterproof blanket expands more than 24 times when it meets water, thus forming a uniform colloidal system, which has the characteristics of high viscosity and low filtration. Under the constraint of two layers of geotextile, bentonite expanded from disorder to order. The result of continuous expansion of water is that the bentonite layer itself becomes dense, thus having a waterproof effect.

  Our company mainly produces needled sodium-based swelling moisturizing waterproof blanket and needled coated sodium-based swelling moisturizing waterproof blanket.

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.

3、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 waterproof blanket construction requirements:

(1) The base should be checked before the construction of the bentonite waterproof blanket, and the base should be compacted and smooth, no pit water, no stone roots and other sharp objects.

(2) Bentonite waterproof blanket in the handling and construction process to avoid vibration and impact as far as possible, to avoid the blanket body has a large curvature, it is best to be in place.

(3) After the installation and acceptance of GCL, backfill work should be carried out as soon as possible. If it is used with HDPE geomembrane, the geomembrane should be welded in time to prevent it from being wet or broken by rain.

6、Bentonite waterproof blanket for finished protection:

(1) After the bentonite waterproof blanket is laid, geomembrane should be laid in time to avoid the erosion of wind and rain;

(2) After the bentonite waterproof blanket is laid, if the geomembrane cannot be laid in time, it should be covered with colored strip cloth or film to avoid weathering the wind and rain;

(3) After the bentonite waterproof blanket is laid, the vehicle rolling and other foreign body damage should be avoided;

(4) After the completion of construction, there shall be no mud, dirt, debris and other foreign bodies that may damage the impermeable layer on the bentonite mat.

(5) The bentonite waterproof blanket (GCL) roll should be stacked in a flat place without water accumulation, the height of the pile does not exceed four rolls, and the identification plate of the roll can be seen.

(6) Damage to bentonite waterproof blanket (GCL) caused by improper storage and operation is not allowed to be used in this project.

(7) The bentonite waterproof blanket (GCL) roll shall be protected from damage during transportation (including on-site transportation from the material storage place to the work).

(8) Physical damage to the bentonite waterproof blanket (GCL) roll must be repaired, severely damaged bentonite mat (GCL) can not be used, we will be removed from the site and replaced.

(9) Any bentonite (GCL) material that comes into contact with the leaking chemical solvent shall, at the discretion of the Supervising Engineer, not be allowed to be used on the project.

(10) If the bentonite blanket is damaged (torn, punctured, etc.) during installation, it can be repaired by cutting a "patch" from a new roll of bentonite blanket over the damaged area. The length of the four sides of the patch should not be less than 300mm from the damaged area, and some granular bentonite or bentonite slurry should be scattered around the damaged area before placing the "patch". If necessary, some adhesive can also be used to prevent the "patch" from shifting, or a small bentonite blanket can be placed under the broken area.
