Yenziwe nge-high density polyethylene (I-HDPE) ishidi, i-polymer eqinile yokusabela kwe-self-adhesive ulwelwesi kanye nongqimba olukhethekile lokuvikela ulwelwesi lokuzihlukanisa.Iwuhlobo lwempahla eyinhlanganisela enezingqimba eziningi engangeni manzi nokusebenza okuphakeme okuthuthukiswe ngokukhethekile izingxenye zamaphrojekthi angaphansi komhlaba adinga ukwakhiwa ngendlela yokugandaywa kwangaphambili.I-material inamandla amahle okuqina namandla okudabula.Iwuhlobo olusha lwempahla engangeni manzi esebenza kahle kakhulu kubunjiniyela obungaphansi komhlaba.
Ngaphansi kwesenzo sokucindezela, i-polymerifilimu yokuzinamathiselafuthi udaka lukasimende ngaphandle kokumiswa kokuqala kukhonkolo luzongena kungqimba oluphikisana nokunamathela ukuze lwakhe isibopho esingenasici esiphumelelayo namandla amakhulu e-intermolecular.Ngemuva kokuthi ukhonkolo uqinisiwe, igebe phakathi kwe-polymer self-adhesive membrane membrane engenamanzi kanye nesakhiwo esiyinhloko sivalwe unomphela kuze kube seqophelweni eliphezulu, futhi isiteshi somzila wamanzi siqedwa ngokuphelele.
| Cha. | Into | Inani Elijwayelekile |
| 1 | Ukuqina /(N/50mm) ≥ | 600 |
| 2 | Ukwelulwa (%) ≥ | 400 |
| 3 | Amandla okudabula intonga yezipikili (N ) ≥ | 400 |
| 4 | Ukumelana nomzila wamanzi (hydraulic gradient) | Akukho umzila wamanzi ku-0.8MPa/35mm isikhathi esingu-4h |
| 5 | Ukuguquguquka kwezinga lokushisa eliphansi | Akukho ukuqhekeka kwesendlalelo sokunamathela - 25 ℃ |
| 6 | Amandla we-peel ngokhonkolo ngaphandle kokwelashwa /(N/mm)≥ | 1.5 |
| 7 | Amandla we-peel ngokhonkolo ngemva kokuguga okushisayo/(N/mm) ≥ | 1.0 |
| 8 | Amandla we-peel ngokhonkolo ngemva kokwelashwa kwe-UV/(N/mm) ≥ | 1.0 |
| 9 | Ukumelana nokushisa | Akukho ukuthutha, ukugeleza nokushelela ku-80℃ isikhathi esingu-2 |
Kusetshenziswa ekwakhiweni kobunjiniyela bokuvikela amanzi nokuswakama kwezakhiwo ezahlukahlukene ezingaphansi komhlaba, amadepho emigede, imigudu, imigwaqo engaphansi kanye nezinye izakhiwo zikamasipala zokwakha njll.
I-HDPE polymer self-adhesive membrane (non-bitumen-based) ishidi elingangeni manzi lenziwe nge-polymer ehlukahlukene.
amashidi njengezinto eziyisisekelo ezimbozwe ngomunye ungqimba oluzinamathelayo kanye nolwelwesi oluhlukanisayo noma ungqimba lwesihlabathi njenge-isolatinglayer.Ngaphezu kwalokho, ishidi le-polymer lihlanganisa amapulasitiki ahlukahlukene afanaI-HDPE, I-TPO, I-PVC, EVA, ECB, kanye elastomer ezifanaI-EPDM.
(1) Yenza “uhlobo lwesikhumba” umphumela wokuvikela amanzi, uqede umsele wamanzi.
(2) Uma ufanelekile, hlanganisa ngokuqondile ukuqinisa futhi uthele ukhonkolo wesakhiwo.
(3) Ukwakhiwa okulula, isikhathi sokwakha esifushane.
(4) Ukubhoboza ukumelana okuhle kakhulu nesimo sezulu, nempilo ende.
(5) Umphumela omuhle wokuhlanganisa.
(1) Imisebenzi kamasipala: Isiteshi sesitimela esihamba ngaphansi komhlaba kanye nomhubhe ohamba ngaphansi komhlaba.
(2) Umgwaqo Omkhulu: Umhubhe onguthelawayeka.
(3) Ujantshi wesitimela onesivinini esikhulu: Umhubhe wesitimela ohamba ngesivinini esiphezulu
(4) Isakhiwo sezimboni nesomphakathi: Isitezi sesisekelo esingaphansi kanye nodonga oluseceleni olwakhiwe ngendlela yokuvimbela kwangaphandle nokunamathisela kwangaphakathi.
