.
Drainage board manufacturer “13184113881” wechat “13184113881” HDPE geomembrane can meet the needs of water conservancy, municipal administration, construction, transportation, subway, tunnel, engineering construction, such as anti-seepage, isolation, reinforcement, crack prevention and reinforcement of civil engineering
.
It can be used in unconventional temperature environment because of high polymer material and anti-aging agent added in production process
.
It is often used for anti-seepage treatment of dykes, drainage ditches, and anti pollution treatment of waste dump
.
Unit area mass unit area mass is the mass of 1 square meter composite geomembrane, which is called the basic mass of composite geomembrane, and the unit is g / m2
.
It is an important index of composite geomembrane
.
For any series of products, the unit price of composite geomembrane is approximately proportional to the mass per unit area, and its mechanical strength increases with the increase of mass
.
Therefore, the quality per unit area is a technical and economic index that must be considered in product selection
.
The drainage board manufacturer “13184113881” wechat “13184113881” refers to the distance between the top surface and the bottom surface of the composite geomembrane under 2KPa atmospheric pressure, in mm
.
The thickness of the composite geomembrane changes with the change of normal pressure, and the pressure of 2KPa is used to express the thickness of the composite geomembrane in the natural state without pressure
.
Recommended reading: how to delay the aging of geotextile? The compression ratio of different types of composite geomembrane varies greatly, among which the compression ratio of needle punched nonwoven composite geomembrane is the largest
.
Therefore, it is necessary to pay attention to the change of hydraulic characteristics caused by the change of overlying pressure when considering the hydraulic characteristics of nonwoven composite geomembrane
.
Drainage board manufacturer “13184113881” wechat “13184113881” is defined as the ratio of pore volume to total volume of nonwoven geotextile, expressed in percentage (%)
.
The index is not directly measured, but calculated according to the mass, density and thickness per unit area
.
The composite geomembrane has a certain amount of deformation, the stress transfer and diffusion speed of concave and convex defects at the bottom is fast, and the strain capacity is strong
.
The pore pressure and buoyancy on the interface between composite geomembrane and soil are easy to dissipate
.
The composite geomembrane has a certain insulation effect, reducing the damage of frost heaving on geomembrane and HDPE geomembrane, thus reducing the deformation of soil
.
The composite geomembrane is laid in an embedded way, which has excellent anti-aging performance and reduces the maintenance and maintenance of the project
.
The construction of composite geomembrane is simple, the transportation volume is reduced, the project cost is reduced, and the construction period is shortened
.
HDPE geomembrane can meet the needs of water conservancy, municipal engineering, construction, transportation, subway, tunnel, engineering construction, such as anti-seepage, isolation, reinforcement, crack prevention and reinforcement
.
It can be used in unconventional temperature environment because of high polymer material and anti-aging agent added in production process
.
It is often used for anti-seepage treatment of dykes, drainage ditches, and anti pollution treatment of waste dump
.
The composite geomembrane uses geotextile instead of granular material as the protective layer of geomembrane to protect the impermeable layer of geomembrane from damage, reduce the grading requirements of cushion particle size, and play the role of drainage
.
The friction coefficient of the composite geomembrane is larger, which can prevent the slip of the covering layer, and has more protective layers than the simple HDPE geomembrane
.
The nonwovens in the composite geomembrane have larger friction coefficient
.
The composite geomembrane can improve the slope ratio and reduce the floor area
.
The tensile strength, tear strength, jacking strength, breakdown strength and other mechanical strength of the composite geomembrane are higher than those of the composite geomembrane manufacturer “13184113881” wechat “13184113881”
.
The advantages of the composite geomembrane are: simple preparation, large transportation volume, low engineering cost and long construction period
.
The anti-seepage effect of geomembrane manufacturers depends on the intact degree of plastic film during construction and operation
.
In order to prevent human and livestock trampling, animal and plant damage and reduce the light and heat effect, as they are high molecular chemical fiber polymers, direct sunlight should be avoided, so the composite geomembrane should be paved with protective layer
.
Composite geomembrane uses geotextile instead of particle data as the maintenance layer of geomembrane, so as to keep the impermeable layer of geomembrane from damage, reduce the grading requirements of cushion particle size, and play the role of drainage
.
Compared with the ordinary HDPE geomembrane, the friction coefficient is larger, which avoids the slip of the covering layer and has more maintenance layers
.
The friction coefficient of Nonwovens in composite geomembrane is large, and the composite geomembrane can improve the slope ratio and air production of geomembrane
