Product Description:

                                       sodium Bentonite Geosynthetic Clay Liner(GCL) for anti-seepage

 

1,Introduction

 

GCL is a new geosynthetics. It is graded by a natural sodium bentonite particles and corresponding additive mixed together, By special technology and equipment, the bentonite particles between two layers of geotextile fixed, made of waterproof blanket, with all the characteristics of both the geotextile material, but also has excellent water (infiltration) performance.

 

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:Read materials science and engineering or civil engineering, it is tangled ah, we discuss together!
I was learning materials, to graduation obviously feel the work of the soil than the material to find good, wages are higher than the material Of course, the material looking for work is also very easy.
Q:What is the meaning of the wetting angle in civil engineering materials?
English name: wetting angle Definition: liquid and solid phase contact point at the liquid-solid interface and liquid surface tangent angle.
Q:What are the new materials in civil engineering?
1 High performance concrete (HPC) requires high durability and high strength, excellent workability, first reflected in the high early strength, high acceptance strength, high elastic modulus; followed by high durability. Can protect the steel is not corroded, used in other harsh conditions, the same can keep the concrete strong and durable; the last high ease of work, pumpability, easy to repair.
Q:What is a civil engineering material?
From the narrow sense of the definition, civil engineering is equivalent to civil engineering, that is, construction (or structural engineering) this small range.
Q:Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
Because the building materials in the civil engineering are used for all aspects of structure, finishes, insulation, filling and so on, there is a need for physical and mechanical technical requirements for building materials to meet the practicality, functionality, durability and beauty of buildings or structures The need for sex.
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:Civil engineering, machinery, materials and finance which relatively good employment?
Civil engineering, basic in the construction industry, machinery, basic in the manufacture of factories or research institutes, materials, basic in research institutes, finance, basic in securities and civil servants, specifically with their own interests and home.
Q:What is the difference between building materials and civil engineering materials?
The contents of civil engineering materials include green building materials, basic properties of civil engineering materials, air and hard inorganic cementitious materials, cement, concrete, mortar, wall materials and roofing materials, steel and aluminum, wood, asphalt and asphalt mixture Materials, waterproof materials, insulation sound insulation sound insulation materials, building decoration materials
Q:Is the glass made of wood?
Glass is not civil material!
Q:Characteristics of Modern Civil Engineering Materials
To understand the characteristics of modern civil engineering materials: 1, high-performance materials, such as the development of lightweight, high strength, high durability, excellent decorative and versatile materials, and make full use of and play a variety of materials, the use of composite technology to create Composite material with special function. 2, make full use of local materials, to minimize the natural resources, extensive use of tailings, waste, garbage and other waste as the production of civil engineering materials resources, as well as the protection of natural resources and maintain the balance of the ecological environment. 3, energy conservation, the use of low energy consumption, no pollution of the production technology, give priority to the development and production of low energy consumption materials and can reduce the energy consumption of buildings using energy-saving materials. 4, the material production should not use harmful to the health of additives and pigments, such as formaldehyde, lead, cadmium, chromium and its compounds, while the development of beneficial materials to the human body, such as antibacterial, sterilization, deodorization, Fire, temperature, degaussing, radiation, anti-static and so on. 5, the product can be recycled in the regeneration of He used, non-polluting waste to prevent secondary pollution.
