Product Description:

GCL Sodium Bentonite Liner Geosynthetic Clay Liners


 

 

Product Introduction

Geosynthetic clay liner is composed of high dilatability of sodium base bentonite filling between the special composite geotextile 

and nonwoven fabric, made by the method of acupuncture or suture composite impervious material. Use acupuncture into 

geosynthetic clay liner can form many small fiber space, make the bentonite particles can't flow in one direction, when under the 

influence of water within the mat forming uniform density of colloidal waterproof layer, prevent the leakage of water. 

For different projects,it can combine HDPE liner for better waterproof.

Bentonite has the expansion of the water characteristics. General calcium base bentonite expands, its expansion is only about 3 times 

their own size; And sodium base bentonite adsorption 5 times its own weight of water in case of water, Volume expansion to the 

original 15 to 17 times above; Lock sodium base bentonite in the middle of the two layers of geosynthetic materials, protecting 

and strengthening the role of, Make the GCL has a certain overall shear strength.

 

Geosynthetic Clay Liner

GCL Feature:

 

1.The permanent waterproof

 

Because sodium base bentonite is a natural inorganic material, even after a long time or the surrounding environment changes, 

also won't happen aging or corrosion phenomena, so the waterproof performance persistence.

 

2. Compactibility

 

Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, 

its permeability is 5 x 10-11 m/SEC below, equivalent to 100 times the compactness of 30 cm thickness of clay, 

have very strong since the water retention performance.

 

 

3.Not affected by temperature

 

In cold climates will not brittle fracture.

 

 

4.Environmental protection

 

Bentonite as natural inorganic material, non-toxic harmless to human body, no special effects to the environment, 

have good environmental performance.

 

 

5.Simple and short time of construction

 

Compared to other waterproofing materials, construction is relatively simple, don't need to be heated and paste. 

With bentonite powder and nails, washers, etc are connected and fixed. After construction does not need special

inspection, if it is found that the waterproof defects and easy to maintenance.

GCL is existing waterproof material in construction period of the shortest.

Q:Civil engineering expertise which to master the technology (specific point of speaking)
Civil engineering is the construction of various types of engineering facilities of science and technology collectively. It refers to the technical activities of the materials, equipment and facilities carried out by survey, design, construction, maintenance and repair; also refers to the object of construction, that is built on the ground or underground, land or water, directly or indirectly for human life Construction, military, scientific research services such as housing, roads, railways, transport pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage and protection works The material basis of the facility is land, building materials, construction equipment and construction machinery. With these material conditions, economic and convenient to build both to meet people's requirements and aesthetic requirements, but also safe to withstand the load of various engineering facilities, civil engineering disciplines is the starting point and destination
Q:Construction and sales business tax how to calculate?
The construction industry applies a 3% business tax rate. The turnover of the construction business tax is the amount of revenue from contracting construction, repair, installation, decoration and other engineering operations. Construction and installation enterprises to the construction unit to collect the project price (ie project cost) and the project price charged outside the various fees.
Q:Civil Engineering Materials.
Civil Engineering Materials. e Material saturated with water, and then dry the surface, is the hole filled with water or closed hole filled with water? What is the condition of putting the material in a jar filled with water? Not to say that the closed hole is not water?
Q:Are building materials the same as civil engineering materials?
Civil engineering includes a wide range of materials, except for buildings, roads, bridges, tunnels and geotechnical materials that are related to civil engineering materials, but many of these materials are not used in industrial and civil construction.
Q:What are the three mechanics of civil engineering?
Material mechanics construction mechanics structural mechanics
Q:What is the actual state of the bar in civil engineering?
(3) to understand and master the cross-section of the cross-section of the torque, torque diagram; (4) mastery of the straight and straight (2) to understand and master the thin-walled cylinder torsion; (5) master the deformation of the straight rod when the deformation, stiffness conditions; (6) to understand and master the straight rod when the strain energy .4 bending stress symmetrical bending of the The calculation of the concept and the calculation of the beam; the shear force equation of the beam and the moment equation, the shear force diagram and the bending moment diagram; the internal force of the plane frame and the curved rod; the normal stress and the normal stress strength condition on the beam cross- (1) to understand and master the concept of symmetrical bending and beam calculation diagram; (2) master the beam of the shear equation and bending moment equation, the shear force diagram of the shear stress, shear stress strength conditions; (3) to understand and master the plane frame and the internal force of the curved rod; (4) master the beam cross-section of the normal stress, normal stress strength conditions; (5) to understand and master the beam cross-section (6) Understand and master the reasonable design of the beam 5. Displacement of the displacement beam when the beam is bent; Define the differential equation and its integral; Define the displacement of the beam; Nuclear, to improve the stiffness of the beam measures; beam bending energy within the beam.
Q:Why civil engineering to solve the problem is to give full play to the role of materials
Material compatibility issues. We all know that the football team has played well, not to the best players in a certain area together, but to cooperate with each other well. The same is true between the different materials.
Q:On the inorganic non-metallic materials engineering (civil materials) jobs and treatment.
This unit seems not stable, very big liquidity, not with the Project run may be better. Treatment are almost it, the general level.
Q:Civil engineering and new materials, which is a good job
Obviously civil, our school is now the situation is graduated in 2017, the civil has been signed, the work tube has not yet begun. Said the prospects of the big tube, a little self-deception, civil construction of the size of the project manager is the vast majority of civil origin, the number of project managers can be ignored, the construction company executives are mostly civil, budget origin. To say that the real estate management of the dominant, just a little funny, real estate is simply not willing to go to the civil, to learn nothing, grow very slowly, most people are more willing to do a few years in the construction unit to go to real estate, Then much more understanding, the growth rate is much stronger than the tube. Since you have learned the civil estimate you know some, if you are a boy, not the kind of people who can not eat a bit bitter, it is recommended not to turn the work tube, the other pipe is relatively simple, the management of things want to learn to get started And soon, if necessary, can work to learn. Of course, the benefits of the work tube, graduated from the management of the degree, but like the general school of this degree of gold can not agree with the degree.
Q:Civil Engineering Materials
And other materials, autoclaved aerated concrete block drying shrinkage, moisture expansion. In construction applications, if the drying shrinkage is too large, in the presence of constraints to prevent deformation, the shrinkage of the formation of the stress exceeds the tensile strength or bond strength of the product, products or seams will appear cracks. In order to avoid cracks in the wall, must be in the structure and construction to take certain measures. And strictly control the moisture content of the product when the wall is also extremely important, it is best to control the wall moisture content of 20% or less
