Uniaxial tensile plastic geogrid

wehewehe pōkole:

Ke hoʻohana nei i ka polymer molecular kiʻekiʻe a me ka ʻeleʻele kalapona nano-scale e like me ke kumu kumu kumu, hana ʻia ia e ka extrusion a me ke kaʻina hana traction e hana i kahi huahana geogrid me ka mesh like ʻole i hoʻokahi ʻaoʻao.

ʻO ka plastik geogrid kahi pahu polimer square a i ʻole rectangular i hoʻokumu ʻia e ka hoʻolōʻihi ʻana, hiki ke uniaxial stretching a biaxial stretching e like me nā kuhikuhi kikoʻī ʻokoʻa i ka wā o ka hana ʻana.Kuʻi ia i nā lua ma ka pepa polymer extruded (ka hapanui o ka polypropylene a i ʻole ka polyethylene kiʻekiʻe kiʻekiʻe), a laila hana i ka hoʻolōʻihi ʻana ma lalo o nā kūlana wela.Hana ʻia ka mānoanoa uniaxially ma ka hohola wale ʻana ma ka lōʻihi o ka lau, ʻoiai ke hana ʻia ka mānoanoa biaxially ma o ka hoʻomau ʻana i ke kikoo uniaxially i hoʻopaʻa ʻia ma ke ala e kū pono ana i kona lōʻihi.

No ka mea e hoʻonohonoho hou ʻia ka polymer o ka plastic geogrid i ka wā o ka hoʻomehana ʻana a me ka hoʻonui ʻana i ka wā o ka hana ʻana o ka geogrid plastic, ua hoʻoikaika ʻia ka ikaika paʻa ma waena o nā kaulahao mole, a ua hoʻokō ʻia ke kumu o ka hoʻomaikaʻi ʻana i kona ikaika.ʻO kona elongation he 10% a 15% wale nō o ka pepa kumu.Inā hoʻohui ʻia nā mea anti-kahiko e like me ke kalapona ʻeleʻele i ka geogrid, hiki iā ia ke hoʻonui i ka lōʻihi e like me ke kūpaʻa ʻana o ka waikawa, ke kūpaʻa alkali, ke kūpaʻa corrosion a me ke kūpaʻa ʻelemakule.

Geogrid hoʻokahi ala

Hoʻokumu ʻia ka geogrid hoʻokahi ala ma ka hoʻokuʻu ʻana i ka polymer molecular kiʻekiʻe i loko o kahi pā lahilahi, kuʻi i ka mesh maʻamau, a laila hoʻolōʻihi lōʻihi.Hoʻohui hui pū oval mesh lōʻihi.He kiʻekiʻe ka ikaika tensile o kēia hale a me ka modulus tensile, ʻoi aku ka nui o nā huahana o kā mākou hui i kahi kiʻekiʻe kiʻekiʻe (elongation rate o 2% --- 5%) ikaika tensile a me ka modulus tensile.Hāʻawi i ka ʻōnaehana hoʻopili ikaika kūpono a me ka diffusion interlock system no ka lepo.Loaʻa ka ikaika tensile kiʻekiʻe o ka huahana (> 150Mpa) a kūpono i nā ʻāina like ʻole.He mea hoʻoikaika nui ia.
