- Q:What is the difference between a nonwoven geotextile and a woven geotextile?
- Q:Concrete pavement or geotextile
- Do not add, with the asphalt Ma plug Seal if you have to choose the best choice for geotextile waterproof the best
- Q:What kind of geotextiles are used to filter the geotextile?
- GBT-1998 geosynthetics staple fiber acupuncture non-woven geotextile GBT-1998 geosynthetics filament spunbond acupuncture non-woven geotextile
- Q:Composite geotextile plastic composite
- 1, plastic composite geotextile is woven with a woven fabric as the substrate, the extruded coated polyolefin resin film or polyolefin resin sandwich layer, the woven cloth and all kinds of Zhang made together. 2, the product made of bags with light weight, acid and alkali resistance, strength, moisture and other advantages. 3, widely used in chemical fertilizer, synthetic resin, coarse salt, ore and cement products such as packaging, is a good packaging of heavy packaging materials
- Q:What is the geotextile customs code?
- Hello: I can only give an example: if you ask the goods belong to the weight per square meter of more than 150 grams of non-woven weaving, can be returned, because you do not have a detailed description of the source of raw materials, production processes, Into the product code under 5603.1410. If you are satisfied with my answer, I would like to be accepted and given praise, thank you!
- Q:Production of acupuncture carpets, geotextiles, warm flakes, paper blankets, air filter materials, the main raw material is what?
- 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.
- Q:What causes the geotextile aging phenomenon
- Gundam has the characteristics of the product we are all obvious, both in the highway, dams, railways and many other occasions have a very strong product features, and the performance is very outstanding, geotextile is an irreplaceable geotechnical material. Although the geotextile has unparalleled advantages, but the product is not perfect that any product has more or less problems or less, geotextile is the same, its aging problem has been with us, then in the end what causes Geotextile aging? Geotextile aging problem refers to the geotextile in the sun by the smell, temperature changes, biological erosion, chemical corrosion, moisture and other external factors, so that the geotextile strength and performance gradually weakened, loss of seepage effect. UV radiation intensity changes with the intensity of solar radiation, geotextile aging speed with the intensity of UV radiation and speed. Synthetic polymer polymer is concerned, the sun radiation is the main factor in the degradation of polymer degradation. UV radiation in the sun is the most important factor in the aging of the fabric. The ultraviolet radiation causes the polymer to produce a photooxidative decomposition reaction, especially ultraviolet light at a wavelength of 290 to 400 mPm, which has a significant decomposition effect on the polymer , Because the geotextile in the range of ultraviolet light energy is higher than the polymer chemical steamed broken the required energy, so the polymer material aging is very obvious.
- Q:Geotextile universal testing machine with 20kn enough?
- Enough, we use is 20kn
- Q:Geotextile geotextile geotextile construction geotextile specific application
- Nonwovens is a major category of textiles, geotechnical construction is its use on the one hand, in this field people call it geotextile. Many types of non-woven fabrics, the specific technical indicators to be determined according to the actual species. Generally measure its raw materials, weight, moisture permeability, tear strength, bursting strong, etc., insulation, moisturizing. Scope: ⒈ water conservancy project dam and slope protection of the filter, channel isolation, anti-seepage. ⒉ road, railway, airport runway foundation isolation, filter, drainage, soil slope, retaining wall and road reinforcement, drainage. ⒊ port engineering soft foundation treatment, beach embankment, harbor wharf and breakwater reinforcement, drainage. ⒋ landfill, thermal power plant ash dam, mine tailings dam isolation, seepage control. ⒌ polyester long fiber anti-sticking acupuncture geotextile has been applied throughout the field of infrastructure construction, and gradually applied to a wider range of areas.
- Q: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.
