Geomembrane Polyethylene Matotoru Iti Rārangi (LLDPE)
Whakaahuatanga Poto:
Ko te geomembrane polyethylene iti-kiato raina (LLDPE) he rauemi ārai-mimi i hangaia mai i te kapia polyethylene iti-kiato raina (LLDPE) hei rauemi mata matua mā te pupuhi, te kiriata whakarewa me ētahi atu tukanga. Ka whakakotahi i ētahi o ngā āhuatanga o te polyethylene nui-kiato (HDPE) me te polyethylene iti-kiato (LDPE), ā, he painga ahurei tōna ki te ngāwari, te ātete ki te poka me te urutau ki te hanganga.

Ngā Āhuatanga Mahi
Ātete Pai rawa atu ki te Pareparenga
He matotoru te hanganga ngota ngota, he iti hoki te tauwehenga uruhanga, ā, ka taea e te geomembrane LLDPE te ārai i te turuturu wai. He rite tonu tōna pānga ārai-mimi ki te geomembrane HDPE, ā, he whānui te whakamahinga mō ngā kaupapa e hiahia ana kia whakahaerea te turuturu.
Ngāwari Pai
He tino ngāwari, ā, kāore e pakarukaru i ngā pāmahana iti, me te awhe ātete pāmahana tata ki te - 70°C ki te 80°C. Mā tēnei ka taea e ia te urutau ki ngā whenua taupatupatu, ki ngā taiao rānei he ahotea hihiri, pērā i ngā kaupapa tiaki wai i ngā rohe maunga he whenua uaua.
Ātete Kaha ki te Wero
He pakari te kiriuhi, ā, he pai ake tōna ātete ki te haehae me te pānga i ērā o ngā kiriuhi maeneene HDPE. I te wā e hangaia ana, ka pai ake tōna ātete ki ngā poka o ngā kōhatu, o ngā mea koi rānei, ka whakaiti i ngā kino tūpono, ka whakapai ake hoki i te pono o te kaupapa.
Te Āheitanga Pai ki te Hanga
Ka taea te hono mā te whakarewa wera-rewa, ā, he kaha te hononga, e ārai ana i te turuturu. I taua wā anō, nā te pai o te ngāwari o te piko me te totoro i te wā hanga, ā, ka pai ake te uru ki ngā turanga uaua pēnei i ngā tinana oneone koretake me ngā pari o te rua turanga, ka whakaiti i te uaua o te hanga.
Ātete Pai ki te Waikura Matū
He kaha tōna ki te ātete i te waikura o ngā wai waikawa, kawakore, me te tote, ā, he pai hoki mō te nuinga o ngā āhuatanga ārai-waikura tuku iho. Ka taea e ia te ātete i te waikura o ngā matū rerekē ki tētahi taumata, ā, ka roa ake te ora o te mahi.
Ngā Āpure Tono
Ngā Kaupapa Tiaki Wai
He pai mō ngā kaupapa ārai-wai o ngā puna wai iti me te rahi-waenga, ngā awaawa, me ngā tāke rokiroki, inā koa i ngā wāhi he uaua te whenua, he taunga koretake rānei, pērā i te hanganga o ngā tāke ārai i te Loess Plateau, ka taea te whakamahi i tōna ngāwari me tōna mahi ārai-wai. Mō ngā kaupapa tiaki wai rangitahi, ā-wā rānei, pērā i ngā tāke rokiroki ohorere mō te tauraki, nā ōna painga o te hanga watea me te utu iti, he mea pai rawa atu.
Ngā Kaupapa Tiaki Taiao
Ka taea te whakamahi hei paparanga ātete-paheke mō ngā whenua ururua iti, hei paparanga ātete-paheke mō te whakahaere i ngā roto wai, me te whakapuru mō ngā roto waipara ahumahi (mō ngā āhuatanga kāore i te tino waikura), hei āwhina i te ārai i te turuturu o ngā poke me te tiaki i te taiao e karapoti ana.
Ahuwhenua me te Whakatipu Ika
He whānuitia te whakamahinga mō te aukati i te turuturu o ngā roto ika me ngā roto kōura, ā, ka taea te ārai i te turuturu o te wai me te whakapai ake i te whai huatanga o ngā rauemi wai. Ka taea hoki te whakamahi mō te aukati i te turuturu o ngā tāke rokiroki whakamakuku ahuwhenua, ngā mīhini keri hau koiora, me te ārai i te makuku me te pakiaka i raro i ngā whare kati kōtuhi, ā, ka taea te urutau ki te āhua rerekē o te oneone nā tōna ngāwari.
Te Waka me te Hangarau ā-Rohe
Ka taea te whakamahi hei paparanga ātete makuku mō ngā papa rori, hei whakakapi i ngā paparanga kirikiri tuku iho, hei whakaiti hoki i ngā utu kaupapa. Ka taea hoki te whakamahi hei ārai i te turuturu o ngā awaawa paipa me ngā kauhanga taura hei tiaki i ngā whare o raro whenua mai i te horo o te wai.
