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:Civil engineering and new materials, which is a good job
Civil engineering looks more easily. Mainly still have to see you apply for the school. If it is a good school of civil engineering graduate, the future development is still very good ~
Q:Civil engineering materials stone test, the determination of stone grade with what practical significance?
Adjust the proportion of sand, stone
Q:Civil Engineering Materials Laboratory electricity about how much watts
Are generally three-phase current, test equipment are needed this.
Q:What are the four major mechanics in civil engineering?
Should be theoretical mechanics, material mechanics, structural mechanics, soil mechanics
Q:What are the basic principles of civil material selection?
The basic principles are mainly security and economy
Q:What is the mechanical nature of the material in the civil material?
Material strength, toughness, stiffness, hardness is the main mechanical properties of the main study object!
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
Q:Questions about civil engineering materials
First, with excellent adhesion, construction, anti-droop, so that the formation of waterproof between the continuum; second, with good flexibility, can withstand structural parts due to temperature, humidity, wind, earthquake And so on caused by the seam deformation; Third, with weather resistance, water resistance, long-term outdoor sunshine, rain, snow and summer heat and other conditions under the effect of maintaining long-term adhesion and tensile compression performance.
Q:The Importance of Civil Engineering Materials in Engineering Construction
Different types of materials, mechanical coefficient, the construction method will be different, the impact of the construction process, the impact of the demand for materials, the impact on the cost of the project impact, the impact on the quality of the project.
Q:What are the civil engineering materials?
Non-mechanical hard cementing materials: lime, gypsum, water glass, magnesia cementitious materials
