Emaphrojekthini obunjiniyela afihliwe—njengemihubhe, imigwaqo engaphansi komhlaba, kanye nemizila yokusetshenziswa komhlaba—izinhlaka zokuvikela amanzi azisebenzi nje njengezithiyo zokuhlukanisa amanzi, kodwa futhi “njengezingxenye eziguquguqukayo” ezihlanganyela ngenkuthalo ekulawuleni ukucindezeleka kwesakhiwo. Njengomkhiqizi okhethekile emkhakheni we-geosynthetics, i-Shandong Hongyue Environmental Engineering Co., Ltd. (ebizwa ngokuthi “i-Hongyue Environmental”) isebenzise ubuchwepheshe bayo obujulile bobuchwepheshe kuzinhlaka zokuvikela amanzi ze-EVA (Ethylene-Vinyl Acetate Copolymer) ukuze yakhe uhlelo lokwakha lwesayensi, oluqinile, nolujwayelekile. Ngokusebenzisa amasu amathathu ayisisekelo—“ukukhetha izinto ezinembile, ukushisela okucophelelayo, kanye nokucindezela okujwayelekile”—inkampani isebenzisa ngokugcwele izakhiwo eziyingqayizivele zezinhlaka ze-EVA, okuhlanganisa ukunwebeka okuphezulu, ukumelana nokushisa okuphansi, kanye namandla okudabula, ngaleyo ndlela isungula ukuzivikela kokuvikela amanzi okungenakungenwa kwezinhlobo ezahlukene zamaphrojekthi obunjiniyela.
Isinyathelo Sokuqala: Ukukhetha Izinto Ezinembile Nokulungiselela I-Substrate—Ukubeka Isisekelo Esingenaphutha
Iphrojekthi yokuvikela amanzi esezingeni eliphezulu iqala ngokulawula okunembile kwezinto zokwakha. Ama-membrane okuvikela amanzi e-EVA e-Hongyue Environmental asebenzisa i-Ethylene-Vinyl Acetate Copolymer yekhwalithi ephezulu njengezinto zawo eziyinhloko zokusetshenziswa; abonisa ukunwebeka okufana nerabha, anokuguquguquka okuhle kakhulu ekushiseni okuphansi (agcina ukugobeka ngisho nasezimweni ezibandayo ezisukela ku--30°C kuya ku--35°C), futhi anamandla amakhulu okudabuka. Ngaphambi kokwakhiwa, i-substrate kumele ilungiswe ngokuqinile: indawo eyisisekelo kumele ibe yicaba, iqine, futhi ingabi nanoma yiziphi izinto ezingalungile noma izinto ezibukhali, ngenkathi ngesikhathi esifanayo iqinisekisa ukuthi ayinawo amanzi amile, amabala kawoyela, nothuli. Kuye ngobukhulu bephrojekthi kanye nendawo yayo yokusebenza ethile, i-Hongyue Environmental inikeza ama-membrane okuvikela amanzi e-EVA enziwe ngokwezifiso ngobukhulu obuhlukahlukene—kusukela ku-0.5 mm kuya ku-2.5 mm—ukuqinisekisa ibhalansi efanele phakathi kokusebenza kwezinto kanye nezidingo zobunjiniyela.
Isinyathelo Sesibili: Izinqubo Eziqinile Zokushisela—Ukunquma Isikhathi Sokuphila Sesistimu Yokuvimbela Ukungenwa Kwamanzi
Ngesikhathi sokwakhiwa endaweni, ukuthembeka kwe-membrane yokuvimbela amanzi kuncike ku-90% kwikhwalithi ye-hot-air welding. Ithimba lobuchwepheshe le-Hongyue Environmental ligcizelela ukuthi umbono ongalungile wokuphatha i-welding nje "njengomsebenzi wokumboza" kumele ulahlwe; esikhundleni salokho, kumele kubekwe phambili njengenqubo ebalulekile nebalulekile. Ukwakhiwa kufanele kwenziwe kusetshenziswa imishini ekhethekile yokushisela noma izibhamu zokushisela zomoya oshisayo, kanti izinga lokushisa lokukhipha umoya lilawulwa ngokuqinile ngaphakathi kobubanzi obungu-320°C kuya ku-380°C. Ngaphambi kokushisela, ububanzi bokugqagqana phakathi kwamashidi e-membrane aseduze kumele bulawulwe ngokunembile phakathi kuka-70 mm no-100 mm, futhi ibhulashi lensimbi kumele lisetshenziswe ukususa ngokuphelele noma yiluphi uthuli olungaphezulu noma izendlalelo ezi-oxidized ezindaweni ezigqagqanayo. Ngesikhathi senqubo yokushisela, amazinga okushisa aphezulu asetshenziswa ukuze kuncibilikiswe ubuso bezinto ze-EVA, kulandelwe ukusetshenziswa kwengcindezi yokuhlanganisa izendlalelo zibe yiyunithi eyodwa, ehlangene. Ukuqinisekiswa kwe-post-welding kuhilela inqubo yokuhlola enezinyathelo ezintathu eqinile: Okokuqala, kwenziwa ukuhlolwa okubonakalayo ukuqinisekisa ukuthi umthungo wokushisela ubonakala njengokuphela okufanayo, okusobala, okufana nengilazi, okungenamabhamuza noma imibimbi. Okwesibili, kwenziwa ukuhlolwa kokukhishwa kwesikhumba ngomshini; lapho amandla okudonsa esetshenziswa ngokuqondile kumthungo wokushisela, kumele ahlale ehlanzekile ngaphandle kokuqhekeka. Okwesithathu, lapho kudingeka khona, kwenziwa ukuhlolwa kokwehla kwamandla ukuze kuqinisekiswe ukuthi noma yikuphi ukubola kwengcindezi kuhlala ngaphakathi kwemingcele ejwayelekile enqunyiwe.
Isinyathelo 3: Ukucindezeleka Kwesayensi Nokubeka—Ukususa Ingozi “Yokushibiliza Okungamanga”
Ngesikhathi sokwakhiwa ezindaweni eziyinkimbinkimbi—njengemiqhele yemihubhe—ukuzithwala kwezinto kungabangela ukuthi zigobe kalula, okuholela “ekushiseni okungamanga” (imisipha engaphelele noma ebuthakathaka). I-Hongyue Environmental Protection igcizelela ngqo isidingo sokusebenzisa indlela “yokushiseni okuhlukaniswe ngezindawo kanye nokushiseni okuhlukaniswe ngezigaba”. Lokhu kuhilela ekuqaleni ukubopha i-membrane yokuvimbela amanzi ku-substrate kusetshenziswa izihlilingi ezikhethekile eziqhelelene cishe ngama-300mm; ukucindezeleka bese kukhishwa ingxenye ngengxenye, bese kushiswa kwenziwa ngasikhathi sinye. Le ndlela ivimbela ngempumelelo ukwenzeka kwe-welds okungamanga okubangelwa ukugoba kwezinto ngaphansi kwesisindo sazo, ngaleyo ndlela kuqinisekiswe isibopho esiqinile, esiseduze phakathi kwe-membrane yokuvimbela amanzi kanye nesakhiwo sokusekela esiyinhloko. Ngaphezu kwalokho, i-membrane yokuvimbela amanzi ye-EVA ibonisa ukuhambisana okubanzi ne-adhesives ehlukahlukene; ngesikhathi sokuphathwa okuningiliziwe kwamakhona, ukungena kwamapayipi, nezinye izindawo eziyinkimbinkimbi, i-adhesives ekhethekile ingasetshenziswa ukufeza ukuvalwa okusheshayo nokusebenzayo, ngaleyo ndlela kuthuthukiswe kakhulu ukungenwa kwamanzi kohlelo lokuvimbela amanzi.
Ngokusebenzisa lolu sethi lwamasu okwakha ajwayelekile, ama-membrane okuvikela amanzi e-EVA e-Shandong Hongyue Environmental Protection ayakwazi ukukhombisa ngokugcwele izinzuzo zawo eziyinhloko—kufaka phakathi ukumelana okungavamile ne-hydrolysis, ukumelana nokungena kwezimpande, kanye nokuphila isikhathi eside kwenkonzo.
