Ama-70% omhlaba angaphansi kolwandle. Kusukela emachwebeni olwandle kuya emabhulohweni amahle asogwini kanye nokufuywa kwezinhlanzi zasolwandle zanamuhla, abantu badale ingcebo engenakubalwa besebenzisa lolu lwandle olukhulu. Kodwa-ke, amathuluzi amahle abalulekile ukuze kuphumelele. Izinto ezivamile ezifana nokhuni, insimbi, kanye nokhonkolo zivame ukuba nezindleko zokulungisa eziphakeme kakhulu kanye nokuphila okulinganiselwe. Ukuthola izinto ezintsha ezingamelana nokugqwala kwamanzi olwandle, ukuvezwa yi-UV, ukuguguleka kwamagagasi, kanye nokubola kwe-biofouling isikhathi eside kubalulekile. I-polyethylene enamandla kakhulu (i-HDPE), ipulasitiki yobunjiniyela, ivele ngokusebenza kwayo okucishe kuphelele, yaba yinto efanelekile yokwakha izikhungo zasolwandle.
Kungani i-HDPE isibe yinto efanelekile?
1. Ukumelana Nokugqwala: I-HDPE ikhombisa ukuqina okuphezulu ngokumelene nama-asidi, ama-alkali, nosawoti, imelana nokugqwala kwamanzi olwandle, futhi ayigqwali njengensimbi evamile noma ibole njengokhuni.
2. Ihlala isikhathi eside futhi ayimelani nokushayisana: Ngisho noma ku--40 degrees Celsius,Amashidi e-HDPEzigcina ukuqina kwazo, zivikela ngempumelelo imithelela evela emikhunjini futhi zibekezelela ukuguguleka kwesikhathi eside okuvela odakeni.
3. Amandla Okunganamatheli: Ubuso obubushelelezi kakhulu bamashidi e-HDPE benza kube nzima ngezilwane eziningi zasemanzini ukunamathela ngokuqinile.
4. Ilula futhi iguquguqukayo kakhulu: Amashidi e-HDPE anobukhulu obungaphansi kwamanzi, okwenza kube lula ukuwafaka nokuwathutha. Angahlanganiswa kalula ngokushisela okuncibilikisiwe ukuze akhe isakhiwo esiqinile nesihlanganisiwe.
5. Okuluhlaza futhi okunobungani nemvelo, okungaphinde kusetshenziswe ngo-100%:Izinto ze-HDPEingasetshenziswa kabusha ngo-100%, okwenza ibe yinto eluhlaza ngempela futhi enobungani nemvelo.
6. Impilo Ende Yesevisi kanye Nezindleko Zokulungisa Eziphansi: Amashidi e-HDPE awadingi ukunakekelwa okulwa nokugqwala noma ukuvikela izinambuzane phakathi nesikhathi sawo sokuphila, okuholela ezindlekweni zokulungisa eziphansi kakhulu.
Idoko elisebenzisa ama-fender okhuni, ngemva kweminyaka eminingana, laqala ukuqhekeka ngenxa yemijikelezo ephindaphindwayo eyomile kanye nokucwiliswa isikhathi eside emanzini olwandle, okudinga ukushintshwa njalo. Ama-fender e-HDPE abe esesetshenziswa esikhundleni salokho. Ukuqina kwalo kuyivumela ukuthi limunce futhi lisakaze amandla okushayisana avela endaweni yokubeka umkhumbi, futhi ukumelana kwalo nokugqwala kanye nokumelana ne-UV kuqinisekisa ukuthi amashidi e-HDPE agcina umbala wawo isikhathi eside, angadingi ukulungiswa kwesikhathi eside futhi anciphise izindleko zokusebenza kwedoko.
Emapulazini e-salmon ase-UK, inqwaba yabantuIshidi le-HDPEozimele bakha izindawo zokulima ezivulekile kanye nekhwalithi yamanzi engcono. Ozimele beshidi abagqwali, futhi izindawo zabo ezibushelelezi ziqeda isidingo sokuhlanza ama-deposit.
Kusukela kuma-dock fenders kuya ezindaweni zokufuya izilwane zasolwandle, izinto ze-HDPE zibonakalise ukusebenza kwazo okuphezulu njengezinto ezifanele kakhulu zemvelo yasolwandle enzima. Ngokuthuthuka okukhulayo komnotho wasolwandle, amashidi e-HDPE, anezici zawo eziphephile, ezihlala isikhathi eside, ezinobungani bemvelo, kanye nezici zazo ezingabizi kakhulu, azodlala indima engenakuphikwa emnothweni oluhlaza okwesibhakabhaka okhulayo, kufaka phakathi amapulatifomu e-photovoltaic asogwini lwelwandle kanye nama-docks anobungani bemvelo.
