Geo Textile Application
Geo Membrane
A geomembrane is very low permeability synthetic polymeric membrane liner or barrier used with any geotechnical engineering related material so as to control fluid migration in a human-made project, structure or system. They are made of (un)reinforced polymeric materials which are used to stabilize earth & secure landfills ensuring containment of hazardous or municipal wastes and their leachates. High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) geomembranes are effective and affordable options in reservoirs for water storage. The composite geomembrane is a kind of geosynthetics which made of more than two kinds of materials such as geotextiles (or fiber glass mesh), polymers (such as PE geomembrane, EVA geomembrane) and so on.
The main physical properties of geomembranes in the as- manufactured state are: Thickness - 60mil as standard (smooth sheet, textured, asperity height), Density, Melt flow index, Mass per unit area (weight), Vapor transmission (water and solvent) . HDPE geomembrane liner is the preferred product for lining projects. HDPE liner is resistant to many different solvents and are the most widely used geomembrane liner in the world. Although HDPE geomembrane is less flexible than LLDPE, it provides higher specific strength and can withstand higher temperatures. HDPE is known for its flexibility, chemical stability, and high strength-to-density ratio. HDPE offers a leak-free system via heat fusion joints. While PVC is stronger and stiffer material, it makes it suitable for direct burial and trenchless installation.
Why Bajaj?
Masterbatches Used In manufacturing Of Geo Membrane
Plast Antistatic
Plast Antistaic Additive Masterbatches are used in Geo membrane applications for enhancing the antistatic properties in Geomembrane. It Opposed Static electricity during works in electrostatic conditions at feild. It also helps in no dust formation which increases weld/seal strenght in feild welding/sealing.
Speciality White Masterbatch
Speciality White Colour Masterbatches Are used in making White Geomembrane Applications.
Specialty Black Masterbatch
Speciality Black Masterbatch are used in making black Geomembrane applications. Black masterbatches enhances the resistive properties of geomembrane. It Opposes the conductivity of the electricity in an application. It protects workers from electrical shocks from geo membrane while working in electrical feild.
UV Masterbatch
UV masterbatches Protects Geo Membranes from harmful UV Rays which can be damage the quality of Geo membranes. It enhanses the heating properties in an Applications. Experience long-lasting brilliance with Bajaj UV Masterbatch—offering unmatched durability and vibrant protection that lasts up to 10-15 years.
Unique Features
Innovative Research and Development
We’ve done continuous innovation in our RnD & state-of-the art technology in manufacturing masterbatches for speciality applications like geosynthetics, ensuring better performance of their structures and reduced long-term maintenance.
Reliability and long-term sustainability
Since the polymer and masterbatch system used in Geo memberane is very much critical to the performance, reliability and long-term sustainability of products we ensure that our products meets the customer’s specifications not only imparting colour but also it does the role of value addition by retaining functional properties in combination with the polymer .
Good Dispersion
Our masterbatches besides providing very good dispersion but also delivers superior performance, as we offer more as a solution (ie) stabilization package that provides excellent long-term thermal stability and life prediction.
Exceed international standards
The right selection of anti-oxidants & UV additives is critical to maintaining the mechanical properties of geosynthetics. We do have expertise in offering additive packages & their incorporation into polymers to produce highly-technical solutions for geosynthetics
ultimate durability
good weldability
optimal balance of mechanical properties
Trouble shooting guide
| PROBLEM | POSSIBLE CAUSES | SOLUTIONS |
|---|---|---|
| BUBBLES IN THE SHEET | Material contains too much moisture | Increase pre-drying time |
| Melt filter screen too coarse | Use fine mesh screen backed by a coarse screen | |
| WRINKLES & CRACKS FORMATION UNDER PRESUSSRE | Air entrapment | Need to maintain perfect camber with uniform thickness & lay flat against a surface without any restraint. |
| Poor lay flat properties | A geomembrane produced without camber will be less likely to wrinkle during installation than one with camber. Eliminating camber depends on the alignment and winding of geomembranes | |
| DETERIORATION OF MEMBRANES AFTER EXPOSURE | Lack of crystallinity & poor ESCR properties | To add more UV & Premium Black MB to HDPE resin to prevent polymer degradation & heat ageing occurring due to solar radiation |
| Lack of sufficient OIT ( oxidation induction time). | Addition of Antioxidant in the resin at proper level for heat stabilization facilitates long term sustenance & durability. |
