Monga tonse tikudziwa, zida zazikulu zopangira ma geomembrane ku China zagawidwa m'mitundu iwiri: makina opaka utoto ndi makina opukutira filimu. Zachidziwikire, zidazo zidzakhala zapamwamba kwambiri, ndipo ma geomembrane opangidwa adzasinthidwa kwambiri pankhani ya zizindikiro zowoneka, zakuthupi komanso zamankhwala. Ndiye kodi ma geomembrane abuluu ndi obiriwira osalowa madzi amakonzedwa bwanji? Mwachidziwitso, kapangidwe kake kakagwiritsidwa ntchito, nthawi zambiri kamapangidwa ndi mbali yakuda ndi yobiriwira kapena yakuda ndi yabuluu. Kuphatikiza apo, nthawi zina mbali zonse ziwiri zimakhala ndi utoto. Kuti zigwiritsidwe ntchito ndi mapulojekiti apadera. Pano, timatcha kuti yakuda-yobiriwira ndi yakuda-yabuluu. Ngati mbali ziwiri zokha za filimu yosalowa madzi yamtundu womwewo zimapangidwa, laminator imatha kuchita izi. Kaya filimu yosalowa madzi yakuda-yobiriwira kapena yakuda-yabuluu imapangidwa, imafunika kupukutidwa pazidazo kuti igwiritsidwe ntchito. Masterbatch yapadera ndi kaboni wakuda wotsutsana ndi UV zimawonjezedwa popanga kuti zikhale zolimba kwambiri.
Kodi ma geomembrane amitundu yosiyanasiyana amatha nthawi yayitali bwanji?
Kawirikawiri, imapangidwira malo otayira zinyalala otsekedwa kapena otsekedwa kwakanthawi, malo otayira zinyalala. Ngati zinyalala zakuda ndi zobiriwira zothira zinyalala, zinyalala zakuda zothira zinyalala zokhala ndi zinyalala zakuda ndi zobiriwira zothira zinyalala zimaphatikizidwa. Mbali yobiriwira iyenera kuyikidwa pamalo otsekedwa; Mofananamo ngati zinyalala zakuda ndi zabuluu zothira zinyalala. Bian Zai anayang'ana mmwamba. Nchifukwa chiyani mbali yamitundu ikuyang'ana mmwamba? Chifukwa imagwiritsidwa ntchito potseka kwakanthawi, mitundu yabuluu ndi yobiriwira imayimira kukongola osati zomera zobiriwira. Idzakhala yayitali kwambiri kotero kuti sipanga makwinya ambiri, idzakhala yolimba kwambiri ndipo idzakhala nthawi yayitali. Zachidziwikire, geomembrane yabuluu ndi yobiriwira imachiritsidwa ndi masterbatch yapadera yamtundu, yomwe sidzazimiririka. Chifukwa imawululidwa ndi dzuwa, siidzapangitsa kuti maziko azitha kusungunuka mwachangu kwambiri ndipo siidzayambitsa ming'alu chifukwa cha kutentha.
Mtengo wa geomembrane yakuda yobiriwira ndi yabuluu wakuda ndi wotani pa mita imodzi?
Kwenikweni, ziwirizi sizimawerengedwa potengera mtengo wa mita imodzi, koma zimayesedwa potengera mita imodzi ya sikweya. Mtengo wa nembanemba yoteteza madzi ndi wapamwamba kuposa wa nembanemba wamba wakuda woteteza madzi. Timagwiritsa ntchito 0.8 mm Thick gauge. Malinga ndi momwe msika ulili pano, mtengo wakale wa nembanemba yoteteza madzi ndi pafupifupi 10200 pa tani. Choyamba, timawerengera kuti kulemera kwa geomembrane ya 0.8 mm ndi magalamu 760, kuchulukitsidwa ndi mtengo wakale wa matani a fakitale, mtengo wa geomembrane yakuda-yobiriwira ndi yakuda-yabuluu yamtunduwu ndi 7.8 yuan /mamita a sikweya. Zachidziwikire, kusakhazikika kwa zinthu zopangira kudzapangitsa kuti mtengo wawo ukwere kapena kutsika.
