Needle punched polypropylene geotextile is made from PP fibres that are tangled together by a needle-punching process. Needle-punched non-woven geotextiles have excellent water flow rates and are used for filtration of soil fines for drainage applications including trench drains, as a wrapping for perforated pipe, for erosion protection, and combined with three-dimensional structures to create prefabricated drains, or as the high-density polyethylene layer to optimize the distribution of pressure, improve soil characteristics of underground walls and foundations.
Case Study
- Location – Thailand
- Product – 500g Polypropylene needle punched geotextile
- Application – Landfill Project
Issue
Thailand is located in the south-central part of the Indo-China Peninsula, bordering Cambodia, Laos, Myanmar, Malaysia, the Gulf of Thailand (Pacific Ocean) to the southeast, the Andaman Sea (Indian Ocean) to the southwest, Myanmar to the west and northwest, Laos to the northeast, and Cambodia to the southeast. As a neighbor, the territory extends south along the Kra Isthmus to the Malay Peninsula, connecting with Malaysia, and its narrow part lies between the Indian Ocean and the Pacific Ocean. With the rapid economic growth, Thailand is also facing more and more serious garbage disposal problems, with more than 50% of its garbage piled in the open air. At present, landfill and incineration, including plastic waste, are the main waste disposal methods in Thailand. This treatment method makes environmental pollution, especially water pollution and marine pollution more serious. Obviously, insufficient construction of waste treatment infrastructure is one of the markets with huge potential.
Solution
The landfill is an important municipal infrastructure for the city, and it is also an indispensable last link in the chain of “reduction, recycling, and harmlessness” of garbage. It is necessary to achieve sustainable landfill through technological upgrading, implement refined and digital management, improve the operation and use efficiency of landfills, and truly realize the value of landfills. For polypropylene geotextile products that are resistant to acids and alkalis and are effective in environmental protection, needle punched polypropylene geotextiles are undoubtedly the most suitable product. The customer found BPM through the company website to understand the detailed information of the polyester geotextile, and sent the specific index requirements by email, and the Thai customer sent the following index requirements for the geotextile:
- Non-woven geotextile made of polypropylene. If you do not use geotextiles produced from used materials (recycled materials).
- The non-woven polypropylene geotextile is manufactured by an ISO 9001 certified manufacturer.
- The non-woven geotextile used by the agent must have a mark showing the name, product type and production number.
- The non-woven fabric must have a certain size, which can catch the damage in the process of environmental protection and self-regeneration.
After a detailed understanding of the project design plan and the in-depth communication between engineers, it is recommended that customers use 500g/㎡ polyester filament geotextile. After the free samples were mailed and tested and passed the project plan, the customer immediately placed the order.
Benefits
- High modulus, high elongation, high strength. – Polypropylene filament needle-punched geotextiles use advanced anti-sticking needle-punching technology to form a unique three-dimensional structure of polypropylene continuous filaments, showing excellent stretch resistance, tear resistance, puncture resistance, etc.; the same weight, poly The tensile strength of acrylic filament needle-punched geotextile is much higher than that of polyester geotextile;
- Acid and alkali resistance – PH2-13 range has almost no effect on performance, can be in long-term contact with cement, fly ash, lime and other alkaline materials, and can be used in landfills, solid waste landfills, saline soil, etc. Maintain stable performance in complex environment without hydrolysis;
- Three-dimensional structure, anti-blocking – The monofilament fineness range is 4D-11D, which is 2-3 times the fineness of polyester geotextile fibers. It can form a stable and uniform three-dimensional pore structure, with excellent water permeability and good blocking resistance;
- Excellent weather resistance. – According to the authoritative certification of the National Frozen Soil Experiment, the high-cold frozen soil and high-temperature and high-humidity climatic environment have almost no effect on the properties of polypropylene filament geotextiles.
- Environmental protection. – The polypropylene material does not contain 23 banned shareable aromatic amines such as aniline which has a harmful effect on the environment. However, polyester materials contain benzene rings, which pollute the environment after hydrolysis.
Summary
Polypropylene geotextile is the optomul product in landfill projects. First of all, the protective function of geotextile is reflected in its bursting strength, thickness and tensile strength. The burst strength of filament geotextile is more than 70% higher than that of staple fiber geotextile. The tensile strength is more than 50% higher. In terms of anti-blocking performance, filament geotextile has obvious advantages. Once clogging occurs, leachate will accumulate in the landfill area, which will bring great difficulties to normal landfill operations and cause hidden accidents.
