Hana ʻia ka geogrid fiberglass me nā filaments fiberglass i ulana ʻia a uhi ʻia

1. ʻIke piha o ka geogrid fiber aniani

He mea geosynthetic maikaʻi loa ka geogrid fiber aniani i hoʻohana ʻia no ka hoʻoikaika ʻana i ke alanui, ka hoʻoikaika ʻana i ke alanui kahiko, ka subgrade a me ke kahua lepo palupalu. He huahana semi-rigid ia i hana ʻia me ke fiber aniani alkali-free ikaika kiʻekiʻe ma o ka ʻenehana ulana warp holomua honua e hana i kahi mea kumu mesh, a laila ka mālama ʻana i ka uhi ʻana o ka ʻili. Hana ʻia ia me nā filaments fiber aniani ma o ke ulana ʻana a me ka uhi ʻana.

2. Nā ʻano o ka geogrid fiber aniani

（1) Nā waiwai mīkini

• Ikaika tensile kiʻekiʻe, elongation haʻahaʻa: Me ka fiber aniani ma ke ʻano he mea maka, he kiʻekiʻe kona kūpaʻa deformation, a ʻo ka elongation i ka haki ʻana he emi ma mua o 3%, ʻo ia ka mea maʻalahi ʻole ke hoʻolōʻihi ʻia a hoʻololi ʻia i ka wā e hāpai ana i nā mana o waho.
• ʻAʻohe kolo lōʻihi: Ma ke ʻano he mea hoʻoikaika, hiki iā ia ke pale aku i ka deformation ma lalo o ke kaumaha lōʻihi, a ʻaʻole e kolo ka fiber aniani, hiki ke hōʻoia i ka hana lōʻihi o ka huahana.
• ʻO ke modulus kiʻekiʻe o ka elasticity: Loaʻa iā ia kahi modulus kiʻekiʻe o ka elasticity a hiki ke pale aku i ka deformation i ka wā e hoʻoluhi ʻia ai, e like me ke kaumaha ʻana i kekahi mau kaumaha i nā hale alanui a me ka mālama ʻana i ke kūpaʻa o ka hoʻonohonoho ʻana.

（2) Ka hiki ke hoʻololi i ka mahana

Paʻa maikaʻi ka wela: ʻo ka mahana hoʻoheheʻe o ke aniani fiber he 1000 ℃. Hōʻoia ka mea i luna i ke kūpaʻa o ka geogrid aniani fiber e kū i ka wela i nā wahi wela kiʻekiʻe e like me nā hana paving, a hiki ke hoʻohana maʻamau i nā wahi anuanu koʻikoʻi, e hōʻike ana i ke kūpaʻa maikaʻi o ka mahana kiʻekiʻe a me ka haʻahaʻa.

（3) Pilina me nā mea ʻē aʻe

• Hoʻohālikelike me ka hui ʻana o ka asphalt: Ua hoʻolālā ʻia ka mea i hoʻopili ʻia i ke kaʻina hana ma hope o ka mālama ʻana no ka hui ʻana o ka asphalt, ua uhi piha ʻia kēlā me kēia fiber a he kiʻekiʻe ke kūlike me ka asphalt, ʻaʻole ia e hoʻokaʻawale mai ka hui ʻana o ka asphalt i loko o ka papa asphalt, akā ua hoʻopaʻa paʻa ʻia.
• Hoʻopili ʻia a me ke kāohi ʻana o ka ʻāwili: ʻO kona ʻano mesh e ʻae i ka ʻāwili i loko o ka sima asphalt e komo i loko, e hana ana i kahi pilina mechanical. Hoʻopaʻa kēia ʻano hoʻopili i ka neʻe ʻana o ka ʻāwili, e ʻae i ka hui asphalt e hoʻokō i kahi kūlana compaction maikaʻi aʻe i ka wā e hoʻouka ʻia ai, hoʻomaikaʻi i ka hiki ke lawe i ka ukana, ka hana hoʻoili ukana, a hoʻemi i ka deformation.

（4) Ka Paʻa

• Paʻa kino a me ke kemika: Ma hope o ka uhi ʻana me kahi mea hana kūikawā ma hope o ka mālama ʻana, hiki iā ia ke kūʻē i nā ʻano ʻaʻahu kino a me ka ʻino kemika, a me ka ʻino olaola a me ka loli o ke aniau, e hōʻoiaʻiʻo ana ʻaʻole i hoʻopilikia ʻia kāna hana.
• ʻO ke kūpaʻa alkali maikaʻi loa a me ke kūpaʻa ʻana i ka wā kahiko: Ma hope o ka mālama ʻana i ka uhi ʻana o ka ʻili, he maikaʻi kona kūpaʻa i nā ʻano like ʻole a hiki ke pāʻani i kahi hana no ka manawa lōʻihi.
