FAQ
- Geotextile 100 meters a roll is about how much diameter
- About 15 meters
- Yes, geotextiles are suitable for high-traffic areas. They are designed to provide stability, erosion control, and reinforcement to the soil, making them an effective solution for areas with heavy foot or vehicle traffic. Geotextiles can help distribute loads and prevent soil compaction, thereby reducing maintenance requirements and extending the lifespan of the area.
- Production of acupuncture carpets, geotextiles, warm flakes, paper blankets, air filter materials, the main raw material is what? why?
- The main raw material is polyester, polyester is the basic composition of polyethylene terephthalate, it is also known as polyester fiber (PET), the long chain of its chemical formula H (OCH2CCOCO) NOCH2CH2OH, the relative molecular weight is generally ~ The In fact, there are a small amount of monomer and oligomers present. These oligomers have a low degree of polymerization and are present in an annular form. Polyethylene terephthalate can be obtained by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG) by direct esterification of ethylene terephthalate 9BHET. From the composition of polyester molecules, it is composed of short fatty hydrocarbon chain, ester, benzene ring, terminal alcohol hydroxyl group. Polyester molecules in addition to the existence of two hydroxyl groups, there is no other polar groups, and thus polyester fiber hydrophilic poor. Polyester molecules contain about 46% of the ester group, ester groups can be hydrolyzed at high temperatures, thermal cracking, the case of alkali is the saponification, the degree of polymerization reduced; polyester molecules also contain aliphatic hydrocarbon chain, it can make polyester molecules have a certain But because the polyester molecules can not rotate the benzene ring, so the polyester macromolecules are basically rigid molecules, molecular chains easy to maintain linear. Therefore, polyester macromolecules in this condition is easy to form crystals, so the polyester crystallinity and orientation is higher.
- The role of geotextiles in geotechnical engineering is to provide reinforcement, separation, filtration, and drainage in construction projects. They are used to enhance the stability and performance of soil or other materials by acting as a barrier, preventing the intermixing of different layers, facilitating water movement, and distributing loads. Geotextiles are commonly employed in road construction, embankments, retaining walls, erosion control, and landfills to improve the overall geotechnical characteristics of the project.
- Filament spunbond nonwoven geotextile performance requirements for what is the basic item
- Filament spunbond acupuncture non-woven geotextile is the implementation of the national standard GB / T-2008 standard. GB / T-2008 standard for filament spunbond acupuncture non-woven geotextile performance requirements of the basic items include: product vertical and horizontal nominal fracture strength (KN / m), vertical and horizontal nominal elongation at break (%) (KN), vertical and horizontal tearing strength (KN), mass per unit area deviation (%), width deviation (%), thickness (mm), vertical permeability coefficient (cm / s), equivalent pore size (O90 (95) / mm). Only the above indicators meet the corresponding GB / T-2008 standard requirements, be considered qualified filament spunbonded non-woven geotextile.
- Yes, geotextiles are commonly used in agriculture. They serve various purposes such as weed control, soil stabilization, erosion prevention, and drainage management. Geotextiles help improve crop yield, reduce maintenance costs, and promote sustainable farming practices.
- Geotextile is what is the role to play with what?
- Geotextile can seep water penetration, this argument is wrong, geotextile itself does not have isolation seepage function, only in the geotextile above the composite geomembrane after it has anti-seepage function, this product is called composite geomembrane, not called Geotextile, geotextile function is the water, the water can be easily through the geotextile, but all the impurities inside the water to stay in the geotextile above, and play a filtering effect, so geotextile also known as anti-geotextile.
- Yes, geotextiles have several environmental benefits. They help prevent soil erosion by stabilizing slopes and embankments, reducing the need for costly erosion control measures. Geotextiles also improve water quality by filtering out pollutants and sediment before they reach water bodies, thus protecting aquatic ecosystems. Additionally, they can promote vegetation growth by providing a stable environment for root development. Overall, geotextiles play a crucial role in sustainable land management and conservation.
