The best geomembrane as liners for reserve sheet
Geomembrane sheet is a polymer product that is considered among geosynthetic products and its most important application is as insulation.
A polymer is an efficient chemical substance that consists of repeating units, many polymeric materials, including geomembranes, are composed of hydrocarbons. Geomembrane is available in the market in the form of sheets with different widths and thicknesses and is widely used in various industries. Geomembrane sheets are generally made of polyethylene or PVC, and their permeability is very low.
Features of the best geomembrane as liners for reserve sheet
geomemberane as liners for reserve sheet has features that make it an insulation and insulation cover in many industries. These features include
It can be welded.
One of the most important features of the best geomembrane sheets is welding, quality sheets are welded well, but it is possible that geomembranes are out of the sealed state and unable to absorb water in different periods of time. For this reason, geomembranes must be maintained. He also paid attention to its repairs. Therefore, both the quality of the sheet and the quality of its welding have an effect on the opening of the weld and the loss of the sealing state of the sheet.
In order to prevent this occurrence, one should buy quality geomembrane sheets, use expert and experienced people to install it, and implement the installation conditions well.
Tolerance or surface thickness difference
A geomembrane sheet does not have a surface with the same thickness. For example, if you have prepared a sheet with a thickness of 2 mm, its thickness is not the same in all parts of the sheet and it may be less or more in some places. The greater the width of the geomembrane sheet, the greater its tolerance.
The color of the best geomembrane as liners for reserve sheet
There are two colors of geomembrane in the market, most of the sheets in the market are blue or black. Among these two colors, black color is preferred because this color is created due to the presence of carbon in the geomembrane sheet, but blue color is mainly created by using blue pigments, which most of the manufacturing factories import these pigments from China. It does not have the necessary quality. For this reason, the blue geomembrane sheet rots earlier than the black one and has a shorter useful life.
The quality of the best geomembrane as liners for reserve sheets
A quality geomembrane sheet consists of 97% heavy polyethylene, 2.5% polypropylene and 0.5% antioxidant. Other factors, such as the production process and how to mix these raw materials, and of course the production machine, also affect the quality of geomembrane production.
One of the important features of the geomembrane sheet is its polished surface. The more polished the surface of the sheet is, the more it reflects sunlight and causes less decay. Therefore, bumps or scratches on the surface of the geomembrane sheet will absorb more light and cause decay.
The best geomembrane as liners for reserve sheet and its types
There are several types of geomembranes available, depending on the primary resin used. The most commonly used geomembranes are listed below.
PVC (polyvinyl chloride) geomembrane is a thermoplastic waterproofing material made of vinyl, softeners and stabilizers.
When ethylene dichloride is converted to dichloride, the result is polymerized to make the polyvinyl chloride resin used for PVC geomembranes.
PVC geomembrane is resistant to tearing, abrasion and puncture and is suitable for construction of canals, landfills, soil amendments, sewage lagoon liners and tank linings.
This material is also great for preserving drinking water and preventing contaminants from entering water sources.
TRP geomembranes
A TRP (reinforced polyethylene) geomembrane uses polyethylene fabric for long-term water retention and industrial waste applications.
Due to their low temperature range, chemical resistance and UV stability, TRP geomembranes are an ideal choice for soil remediation, landfills, canals, temporary retention pond linings, agricultural and municipal applications.
HDPE geomembranes
High-density polyethylene (HDPE) is characterized by strong UV/temperature resistance, low material cost, durability, and high chemical resistance.
It is the most commonly used geomembrane because it offers a higher thickness than other geomembranes. HDPE is the preferred choice for pond and channel lining projects, landfills and tank linings.
Due to its chemical resistance, HDPE can be used as the best geomembrane sheet for potable water storage.
LLDPE geomembranes
LLDPE (linear low density polyethylene) geomembrane is made with virgin polyethylene resins, which makes it strong, durable and resistant to UV rays and low temperatures.
Engineers and installers who need an impermeable geomembrane usually choose LLDPE because it offers more flexibility compared to HDPE.
They are used in industrial applications such as animal and environmental waste containers as well as liquid storage tanks.
RPP geomembranes
RPP (reinforced polypropylene) geomembranes are polyester-reinforced liners made from a UV-stabilized polypropylene copolymer that gives the material stability, chemical resistance, and flexibility.
Its strength and durability can be traced to the support it receives with nylon scrim. RPP geomembranes are ideal for long-term water retention and industrial waste applications.
RPP for urban applications, linings of evaporation ponds, aquariums, etc
Aghbani and mine tailings are excellent.
EPDM geomembranes
EPDM geomembrane (Ethylene Propylene Diene Monomer) has a rubber-like texture that makes it durable, UV resistant, strong and flexible.
They are ideal for extreme weather conditions and for puncture resistance. EPDM geomembranes are easy to install and are commonly used as surface barriers for dams, liners, revetments, backyard landscaping and other irrigation sites.
