Ingabe Izinto Ezinamathelayo Zesakhiwo Zingenwa amanzi? Umhlahlandlela ophelele futhi osebenzayo
Ukusebenza okungangeni kwamanzi kokunamathela kwesakhiwo kuncike ohlotsheni oluthile kanye nesimo sohlelo lokusebenza; ukukhetha okuhlosiwe kuyadingeka ukuze kuvalwe kahle ukuvuza.
Umsebenzi oyinhloko wezinamatheliso zesakhiwo ukubopha ngamandla-okuphezulu, kuyilapho ukusebenza kwawo okungangeni manzi kuyahlukahluka kuye ngokuthi kwakhiwe kanjani. Izinamathiselo zesakhiwo se-silicone (njengohlobo lwe-995) ziyisinqumo sokuqala sokuvimbela amanzi ngaphandle, ukunikeza ukumelana nelanga nesithwathwa, okufanelekile ophahleni kanye nezihlanganisi zodonga lwangaphandle; izinamatheliso zesakhiwo se-polyurethane (ezifana ne-E60HP) zenzelwe ngokukhethekile izindawo ezinomswakama, ezinikeza ukunwebeka nokumelana nesikhutha, ezifanele izindlu zangasese namakhishi; izimboni{4}}ezinamathelayo zesakhiwo (ezifana ne-Loctite AA 352) zingaphatha izinto ezisetshenziswa ngaphansi kwamanzi, kodwa zidinga ukuhlanganisa okuqinile. Qaphela ukuthi izinto ezinamathelayo ezijwayelekile zesakhiwo zinikeza kuphela-ukuvikelwa kwesikhashana kokuchaphazeka futhi zivame ukwehluleka ngemva kokucwiliswa isikhathi eside emanzini.
Isimo{{0}sokukhetha okusekelwe kufanele kulandele izimiso ezintathu: Okunamathelayo kwe-silicone kukhethwa endaweni yangaphandle, kuhlala kuzinzile kuwo wonke amabanga okushisa ukusuka -ku-40℃kuya ku-150℃; Izinamatheliso ze-polyurethane zinconywa ezindaweni ezinomswakama, njengoba zanda futhi zinkontileka ngamathayili; Imikhiqizo yezimboni-yezinga kumele isetshenziswe ezindaweni ezikhethekile (njengamamotho namathangi amanzi). Izibonelo zomhlaba wangempela zibonisa ukuthi umsebenzisi usebenzise i-Qiandinghe 9900 uhlobo lwe-silicone sealant iminyaka emithathu ngaphandle kokugeleza kwamanzi, kodwa i-substrate yonakaliswa ngesikhathi sokususwa ngenxa yokunamathela ngokweqile.
Kunemibono emithathu eyiphutha evamile ekhona enqubweni yokwakha: Okokuqala, akuzona zonke izinto ezinamathelayo zesakhiwo ezingenamanzi; isibonelo, uhlobo 998 ludinga ukusetshenziswa kwe-sealant.
Okwesibili, ukuhlanzwa okungaphelele kwe-substrate (njengezinsalela zamafutha) kungaholela esibophweni samanga, kubangele ukuthi iphrojekthi ivuze futhi idinga ukusetshenzwa kabusha ngemva kwezinyanga ezintathu. Okwesithathu, izingqimba ezinamathelayo eziminyene ngokweqile zivame ukuqhekeka; igumbi lokugezela elilodwa lalidinga ukulungiswa okuphelele kokuvimbela amanzi ngemva kwezinyanga eziyisithupha ngenxa yokufakwa okunamathelayo okuminyene ngokweqile.
Isixazululo esithuthukisiwe siwukusebenzisa ukuvimbela amanzi okuhlangene: ngemva kokugcwalisa amalunga nge-adhesive yesakhiwo, sebenzisa i-polyurethane coating, noma uqale usebenzise i-butyl tape bese usebenzisa i-adhesive, udale ukuvikeleka kabili. Lolu hlobo lwesixazululo luvamile-ezimeni ezidingekayo njengendawo yangaphansi namachibi okubhukuda.
Ukuvimbela amanzi okunamathelayo kwesakhiwo kufanele kulandele-indlela yezinyathelo ezintathu "yokukhetha, ukwakhiwa, kanye nokuhlanganiswa." Ukufanisa ukusebenza komkhiqizo nesimo, ukunamathela ngokuqinile ezinkambisweni zokusebenza, kanye nokwengeza nezinye izinto zokuvikela amanzi kubalulekile ukuze kufinyelelwe{2}}uphawu oluhlala njalo futhi kugwenywe ukwenyuka okukhulu kwezindleko zokulungisa kamuva.
