Ka noi ʻana i ka nila Felting - geotextiles

ʻO Geotextile, ʻike ʻia hoʻi he geofabric, i hana ʻia me nā fiber synthetic ma o ka neʻe ʻana a i ʻole ka ulana ʻana i nā mea geosynthetic wai-permeable. ʻO Geotextile kekahi o nā mea geosynthetic hou, ʻo ka huahana i hoʻopau ʻia he lole, ʻo ka laulā ākea he 4-6 mika, ʻo ka lōʻihi he 50-100 mika. ethylene fiber a me nā mea ʻē aʻe nonwoven geotextiles e like me nā mea maka. ʻO ka geosynthetic ka wai permeability, ka pale ʻana i ka corrosion, ke kūpaʻa ʻana, ka ikaika tensile kiʻekiʻe, ke kū ʻana o ka wā kahiko a pēlā aku. ʻO Geotextile kahi ʻano mea geotechnical i hoʻohana nui ʻia i ke kūkulu ʻana i nā alanui, nā loko, nā tunnels, DAMS a pēlā aku. ʻO kāna mau hana nui ka hoʻokaʻawale ʻana, kānana, hoʻokahe, hoʻopaʻa a me ka hoʻoikaika. Ma muli o kāna noi nui a me ka mea nui, ʻo ka ikaika tensile, ka haki ʻana, ka permeability a me ka paona lole a me nā waiwai ʻē aʻe he koi kiʻekiʻe loa. ʻO ka nila hōkū o ka nila Hengxiang ka mea kūpono loa no ka hana ʻana i ka geotextile ikaika kiʻekiʻe, ʻoi aku hoʻi no ka hana ʻana i ka fiber staple artificial a ʻoi aku ka maopopo o ka lole wili pālolo. ʻO ka nila hoku o nā spines makau ʻehā ʻaoʻao e hiki ai i ke kiʻekiʻe o ka hoʻopili ʻana a hoʻemi i ka pōʻino o nā fiber. Nui nā ʻano fiber i hoʻohana ʻia e hana i nā geotextiles, e pili ana i ka noi kikoʻī. ʻO nā mea maʻamau he polyester, polypropylene, a me ka nylon. ʻO ka mānoanoa o ka fiber ka mea maʻamau ma waena o 4 a me 10 danela, me kekahi mau huahana e hoʻohana ana i kahi fiber mānoanoa. ʻO ka hohonu o ka needling he 10 a 12mm, a ʻo ka nui o ka needling he 100 a 400 mau nila no C square mika. Pono ka mīkini palolo wili kiʻekiʻe me ka wikiwiki o 2000 a 3000 mau kākalaioa i kēlā me kēia minuke, a ʻoi aku ka haʻahaʻa. ʻO ka maʻamau ka mīkini needling nui he 100 a 300 mau kākalaioa no C mika square, a ʻo ka hohonu needling i ʻōlelo ʻia he 10 a 12mm.
