Umubiri w'umuyoboro wa polyethylene yo hasi (LLDPE) ufite ubucucike buciriritse
Ibisobanuro bigufi:
Geomembrane ya polyethylene ifite ubucucike buke (LLDPE) ni ibikoresho bya polymeri bidasohoka bikozwe muri resin ya polyethylene ifite ubucucike buke (LLDPE) nk'ibikoresho by'ingenzi binyuze mu gupfuka, filime ikozwe mu cyuma n'ibindi bikorwa. Ihuza bimwe mu biranga polyethylene ifite ubucucike bwinshi (HDPE) na polyethylene ifite ubucucike buke (LDPE), kandi ifite ibyiza byihariye mu koroha, kudapfumuka no kwihutisha inyubako.

Ibiranga Imikorere
Ubudahangarwa bwiza bwo kumena amazi
Ifite imiterere y’uturemangingo twinshi kandi ifite ubushobozi buke bwo kwinjira, LLDPE geomembrane ishobora gukumira amazi ava. Ingaruka zayo zo gusohoka zishobora kugereranywa n’iza HDPE geomembrane, bigatuma ikoreshwa cyane mu mishinga isaba kugenzura amazi ava.
Guhindura imiterere y'umubiri neza
Igaragaza ubushobozi bwo koroha cyane kandi ntiyoroshye kwangirika iyo ubushyuhe buri hasi, ifite ubushobozi bwo kwihanganira ubushyuhe buri hagati ya - 70°C na 80°C. Ibi bituma ishobora kumenyera ubutaka butari bumwe cyangwa ibidukikije bifite imbaraga zidasanzwe, nko mu mishinga yo kubungabunga amazi mu turere tw’imisozi dufite ubutaka bugoye.
Ubudahangarwa bukomeye bwo gupfumura
Uru rusobe rufite imbaraga zikomeye, kandi kurwanya kwangirika no gukomereka kwarwo ni byiza kurusha urw’urusobe rworoshye rwa HDPE. Mu gihe cyo kubaka, rushobora kwihanganira gutoborwa n’amabuye cyangwa ibintu bityaye, bigagabanya kwangirika ku bw’impanuka no kunoza uburyo umushinga wizewe.
Uburyo bwiza bwo guhuza n'imiterere y'ubwubatsi
Ishobora guhuzwa no gusudira ishyushye, kandi imbaraga z'ingingo zikaba nyinshi, bigatuma amazi agabanuka neza. Muri icyo gihe, ubushobozi bwayo bworoshye bwo kuyigora no kuyirambura mu gihe cyo kuyiyubaka, kandi ishobora gushyira neza ishingiro rigoye nk'ubutaka butaringaniye n'ubuso bw'urufatiro, bigabanura ingorane zo kubaka.
Ubudahangarwa bwiza ku binyabutabire
Ifite ubushobozi bwo kurwanya ingese y’ibinyabutabire bya aside, alkali n’umunyu, kandi ikwiriye ibintu byinshi bisanzwe bidashobora gushonga. Ishobora kwihanganira ihungabana ry’ibintu bitandukanye bya shimi ku rugero runaka no kongera igihe cyo kuyikoresha.
Ahantu ho Gusaba
Imishinga yo kubungabunga amazi
Ikwiriye imishinga idashonga y’amazi y’ibigega bito n’ibiciriritse, imiyoboro, n’ibigega byo kubikamo amazi, cyane cyane mu turere dufite ubutaka bugoye cyangwa ahantu hatangana, nko kubaka ingomero zo kugenzura amazi kuri Loess Plateau, aho ubushobozi bwayo bworoshye bwo kunyura no kunyuramo amazi bushobora gukoreshwa. Ku mishinga yo kubungabunga amazi y’igihe gito cyangwa mu bihe by’izuba, nko mu bigega byo kubika amazi byihutirwa, ibyiza byayo byo kubaka byoroshye no ku giciro gito bituma iba amahitamo meza.
Imishinga yo Kurengera Ibidukikije
Ishobora gukoreshwa nk'ahantu ho gusohora imyanda by'agateganyo - ahantu hadakoreshwa imyanda ku myanda mito, aho amazi asohoka - ahantu ho kugenzura ibyuzi, n'aho amazi yanduye yo mu nganda (mu bihe bitangiza cyane), bifasha mu gukumira imyanda no kurinda ibidukikije biyikikije.
Ubuhinzi n'Ubworozi bw'Amafi
Ikoreshwa cyane mu gukumira amazi y’ibidendezi by’amafi n’ibyuzi by’ibishishwa, bishobora gukumira amazi atemba neza no kunoza ikoreshwa ry’amazi neza. Ishobora kandi gukoreshwa mu gukumira amazi y’ibigega byo kubikamo amazi mu buhinzi, ibigega bikoresha biogas, no gukumira amazi y’ubushuhe n’imizi y’ibishishwa mu gukurura amazi mu butaka bw’inzu zitunganya ibiti, kandi ishobora kwimenyereza guhindura ubutaka bitewe n’uko bworoshye.
Ubwikorezi n'Ubwubatsi bw'Umujyi
Ishobora gukoreshwa nk'urwego rurinda ubushuhe ku nzira z'umuhanda, gusimbuza urwego rusanzwe rw'amabuye y'agaciro no kugabanya ikiguzi cy'umushinga. Ishobora kandi gukoreshwa mu gukuramo imyobo y'imiyoboro yo munsi y'ubutaka n'imiyoboro y'insinga kugira ngo irinde amazi yo munsi y'ubutaka kwandura isuri.
