PET Polyester multifilament ulana geotextile keʻokeʻo geofabric
Hana ʻia nā geotextiles me ka polypropylene ʻoihana ikaika kiʻekiʻe, polyester, polyamide a me nā fiber synthetic ʻē aʻe e like me nā mea maka ma ke kaʻina hana ulana.

Nā hiʻohiʻona huahana:
Ka ikaika kiʻekiʻe: e hoʻohana i ka polypropylene ʻoihana ikaika kiʻekiʻe, polyester, nylon a me nā fiber synthetic ʻē aʻe e like me nā mea maka, me ka ikaika kumu kiʻekiʻe. Ma hope o ka ulana ʻia ʻana i loko o ka hoʻolālā interweave maʻamau, hoʻomaikaʻi hou ʻia ka hiki ke hali.
Ka lōʻihi: ʻike ʻia ka fiber synthetic e kona kūʻē ʻana i ka denaturation, decomposition a me ka weathering. Hiki ke mālama i kona mau ʻano kumu no ka manawa lōʻihi.
Ka pale ʻana i ka corrosion: ʻo ka fiber kemika synthetic maʻamau ka pale ʻana i ka waikawa, ka pale alkali, ke kūpaʻa ʻana i ka moth, ke kūpaʻa ʻana.
Hiki i ka wai: Hiki i nā lole ulana ke hoʻomalu maikaʻi i ko lākou mau pores kūkulu e hoʻokō i kahi nui o ka wai permeability.
ʻO ka mālama kūpono a me ka lawe ʻana: ma muli o kona kaumaha māmā, hiki ke hoʻopaʻa ʻia e like me kekahi mau koi, no laila ua maʻalahi ia no ka lawe ʻana, mālama a me ke kūkulu ʻana.
ʻAʻole pili ka maikaʻi e ka ʻokoʻa wela o ~-30 ℃;
Noi:
Hoʻohana nui ʻia i ka mālama wai, ka uila, nā mines, nā alanui a me nā kaʻaahi a me nā ʻenehana geotechnical ʻē aʻe,
ka nui o na hana penei:
Kaʻaahi, alaloa, kahua mokulele hoʻoikaika subgrade mea,
mea hoʻoikaika i ka hana alanui marsh,
hau, mea hoohuoi hau,
mea pale ʻana i ka pohā o ke alanui asphalt,
mea kānana hoʻokaʻawale papa lepo,
waihona, mea waiwai hoʻoheheʻe mai iaʻu,
hale kiʻekiʻe hale hoʻoheheʻe waiwai,
kahawai, pale slope mea anti-erosion.
