He aha ka geomembrane?

ʻO Geomembrane kahi mea geomembrane i haku ʻia me ka kiʻiʻoniʻoni plastik e like me ka substrate impervious a me ka lole nonwoven.ʻO ka hana impervious o ka geomembrane mea hou e hilinaʻi nui i ka hana impervious o ke kiʻiʻoniʻoni plastik.ʻO nā kiʻiʻoniʻoni plastik i hoʻohana ʻia no ka pale ʻana i ka seepage ma ka home a me nā ʻāina ʻē he nui ka polyvinyl chloride (PVC), polyethylene (PE), a me EVA (ethylene/vinyl acetate copolymer).Ma nā noi tunnel, aia kekahi mau hoʻolālā e hoʻohana ana i ka ECB (ethylene acetate modified asphalt blend geomembrane).He mau mea maʻalahi kemika polymer me ka umekaumaha kikoʻī liʻiliʻi, ka hoʻonui ikaika, ke kūpaʻa deformation kiʻekiʻe, ke kūpaʻa corrosion, ke kūpaʻa haʻahaʻa haʻahaʻa, a me ke kūpaʻa hau maikaʻi.

ʻO Geomembrane kahi mea wai a me ka mea pale e pili ana i ka polymer.

Hoʻokaʻawale ʻia ia i: geomembrane haʻahaʻa haʻahaʻa polyethylene (LDPE), geomembrane polyethylene (HDPE) kiʻekiʻe, a me EVA geomembrane.

1. Ua piha ka laulā a me ka mānoanoa.

2. Loaʻa iā ia ka maikaʻi o ke koʻikoʻi o ke kaiapuni i ka haki ʻana i ke kūʻē a me ka maikaʻi o ke kūʻē ʻana i ka corrosion.

3. ʻOi aku ka maikaʻi o ke kūʻai ʻana i ka corrosion.

4. Loaʻa iā ia kahi pae wela hana nui a me ke ola lawelawe lōʻihi.

5. Hoʻohana ʻia ma nā kahua hoʻopaʻa ʻāina, nā kahua mālama huelo, ka pale ʻana i ke kahawai, ka pale ʻana i ka embankment seepage, a me nā papahana subway.

ʻO kāna hana nui, ʻo ia ka hoʻokaʻawale ʻana i ka leakage o ka pā honua me ka impermeability o ka kiʻiʻoniʻoni plastik, e kū i ke kaomi wai a hoʻololi i ka deformation o ke kino dam me kona ikaika tensile nui a me ka elongation;ʻO ka lole ʻaʻole i ulana ʻia kekahi ʻano o ka polymer fiber chemical material, ka mea i hana ʻia e ka kui kui a i ʻole ka hoʻopaʻa ʻana i ka wela, a he kiʻekiʻe ka tensile ikaika a me ka extensibility.Ke hui pū ʻia me ka kiʻiʻoniʻoni plastik, ʻaʻole ia e hoʻonui wale i ka ikaika tensile a me ka hoʻopaʻa ʻana o ka kiʻiʻoniʻoni plastik, akā e hoʻonui pū i ka coefficient friction o ka ʻili pili ma muli o ka ʻili o ka lole i ulana ʻole ʻia, kahi kūpono i ka paʻa o ka composite. geomembrane a me ka papa pale.I ka manawa like, loaʻa iā lākou ke kūpaʻa corrosion maikaʻi i ka bacteria a me ka hana kemika, ʻaʻole makaʻu i ka waika, alkali, a me ka paʻakai paʻakai, a he lōʻihi ke ola lawelawe ke hoʻohana ʻia i kahi pōʻeleʻele.
