Product Description:

                                       sodium Bentonite Geosynthetic Clay Liner(GCL)

 

1,Introduction

 

bentonite geotextile clayliner is composed of 3 levels. The upper level and the lower level are woven geotextile  and non woven textile. 

The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. 

The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. 

 

2,Feature

(1) A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up to 1.0MPa above, permeability coefficient 5 *10-9cm / s. Because the Department of Natural sodium bentonite inorganic materials, even after a long time or the surrounding environment changes, aging or corrosion does not occur.

 

(2) Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction. Just when construction GCL waterproof blanket tile on the floor, when the elevation or slope construction, with nails and washers to secure it, as required, can overlap.

 

(3) Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.

 

(4)green: Bentonite is a natural inorganic material, harmless, non-toxic, no particular impact on the environment, with good environmental performance.


(5) simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste. Product width up to 6 meters, with international geotextile (film) to match the size, greatly improving the efficiency of construction.

 

(6) Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.

 

3,Application

(1)Municipal engineering, underground engineering subways, buildings and roofs reservoir seepage.

(2)Environmental sanitation, solid waste landfills, sewage treatment plants, industrial waste.

(3)water, rivers, lakes and reservoirs dam seepage, plugging, reinforcement.

(4)Garden artificial lake golf course pond seepage and so on.

(5)Petrochemical, mining and other areas of engineering seepage, leakage, etc.

Q:Help students learn sister, civil engineering materials
Mortar, steel, masonry, wood, synthetic polymer, waterproof material, decorative materials
Q:What are the types and properties of commonly used civil engineering materials?
Classification by material source According to the material source, can be divided into natural materials and man-made materials. The man-made materials can be metallurgical, kiln (cement, glass, ceramics, etc.), petrochemical and other materials manufacturing sector to classify.
Q:What are the basic principles of civil material selection?
Economy: should be drawn from the convenience, simple construction, construction cycle length, and whether the recovery and other considerations
Q:The relationship between material development and civil engineering development
The development of civil engineering depends on the development of materials, the application of new materials, reducing the cost of civil engineering costs. Such as the emergence of light steel structure, the emergence of insulation board building energy has been a breakthrough, and so on. There are three major mechanics in civil engineering; theoretical mechanics; material mechanics; structural

Q:What are the requirements for civil engineering materials?
See if you are studying or working at the site
Q:The gap between China 's civil engineering building materials and abroad
Foreign understanding of Civil Engineering, so research and research materials, research and research computer, research and research methods and equipment, is not honest, and professional relationship can be big. By turning the Ministry of Education disciplines, you will find that in fact China's civil is also divided into structure, bridge and tunnel, geotechnical, municipal, disaster prevention and other directions, in fact, including a lot of things. As a very end application of the engineering disciplines, not self-limiting, and constantly try to cross the breakthrough should be righteous.
Q:Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
As the pavement material, asphalt mixture, wear resistance, tensile strength, high temperature stability and durability, etc .; as the roof Waterproof material, the need for tensile strength, elongation at break, low temperature flexibility, impermeability, anti-aging properties
