Ngokusekelwa emhlabeni wonke kanye nokukhuthazwa kwezakhiwo ezakhiwe ngaphambili, imboni yezokwakha ingene kancane kancane enkathini yezimboni, ngakho-ke siyini ngempela isakhiwo esakhiwe ngaphambili?Kalula nje, izakhiwo ezakhiwe zifana namabhulokhi wokwakha.Izingxenye zikakhonkolo ezisetshenziswa esakhiweni zakhiwe kusengaphambili embonini, bese zithuthelwa endaweni yokwakha ukuze ziphakanyiswe, zihlanganiselwe futhi zihlanganiswe ukuze zakhe isakhiwo.
Buyini ubudlelwano phakathi kwezakhiwo ezakhiwe kuqala kanye ne-MS sealant?
Ngenxa yokuthi izakhiwo ezakhiwe kusengaphambili zihlanganiswa kusukela ezingxenyeni ezakhiwe embonini, nakanjani kunezikhala ezithile zokuhlanganisa phakathi kwezingxenye.Ukugcwalisa lezi zikhala zomhlangano kubaluleke kakhulu.Njengamanje, kunezinhlobo ezintathu zama-sealant wokwakha asebenza kakhulu emakethe: i-silicone, i-Polyurethane ne-polysulfide, i-MS sealant ihlukile kunoma iyiphi yalezi zinsimbi ezintathu.Kuyi-silicone-modified polyether sealant ezuza ngokwesakhiwo izici zesakhiwo se-silyl esibulalayo kanye ne-main chain polyether bond structure, ehlanganisa izinzuzo ze-polyurethane sealant kanye ne-silicone sealant ngokusebenza, isiqondiso esibalulekile sokuthuthukiswa okusha. ama-sealants ekhaya naphesheya.
Ngakho-ke yiziphi izinzuzo ze-MS sealant uma ziqhathaniswa nama-sealant okwakha enziwe ngaphambili?
1.Izinga eliphezulu lokululama lokunwebeka kanye namandla okugudluza aqinile
Ngoba amalunga ama-slabs kakhonkolo azokwandiswa, ukufinyezwa, ukuguquguquka nokugudluzwa ngenxa yokushintsha kwezinga lokushisa, ukuncipha kokhonkolo, ukudlidliza okuncane noma ukuxazululwa kwesakhiwo, njll., ukuze kuvinjwe i-sealant ukuthi ingaqhekeki futhi kuqinisekiswe ukubopha nokubekwa uphawu okuphephile nokuthembekile. yamajoyinti, i-sealant esetshenzisiwe kufanele Inezinga elithile lokunwebeka futhi inganwebeka ngokukhululekile futhi inkontileka ngokuvula nokuvala ukuguquguquka kwesihlanganisi ukuze kugcinwe ukubekwa uphawu.Umthamo wokugudluza we-sealant kufanele ube mkhulu kunokususwa okuhlobene komthungo webhodi.Ngeke idabuke futhi iqine ngesikhathi sokuwohloka okuphindaphindiwe komjikelezo.Ibhobokile, ingagcina futhi ibuyisele ukusebenza kwayo kwasekuqaleni kanye nokuma kwayo.Ngemuva kokuhlolwa, izinga lokululama elinwebekayo, umthamo wokugudluzwa kanye ne-tensile modulus ye-MS sealant konke kudlule izidingo ezijwayelekile zikazwelonke, futhi inezinto ezinhle zomshini.
2. Ukumelana nesimo sezulu esihle kakhulu
Ku-JCJ1-2014 "Imithetho Yezobuchwepheshe Yezakhiwo Zokhonkolo Ezakhiwe Kade", kushiwo ngokucacile ukuthi izinto zokuvala ezikhethelwe amalunga okwakha ngeke nje zihlangabezane nezidingo zokusebenza kwemishini ngaphandle kokumelana ne-shear kanye nokwandiswa kanye namandla okuguga, kodwa futhi zihlangabezane nokumelana nesikhutha, ukungangeni manzi, Ukwakha izidingo zokusebenza ngokomzimba ezifana ukumelana nesimo sezulu.Uma impahla ingakhethiwe kahle, i-sealant izoqhekeka, ihluleke ukufeza umphumela wokuvala, ngisho ne-sealant izohluleka, okuzothinta ukuphepha kwesakhiwo.Isakhiwo se-MS sealant siyi-polyether njengeketango eliyinhloko, futhi iqukethe namaqembu e-silyl anamaqembu asebenzayo okwelapha.Inikeza ukudlala okugcwele izinzuzo ze-polyurethane sealant ne-silicone sealant, futhi kuthuthukisa kakhulu ukumelana nesimo sezulu se-sealant.
3. ukupendeka okuqinile, ukuvikelwa kwemvelo kanye nokungangcoli
Ngenxa yokuthi i-MS glue inezinzuzo zazo zombili i-polyurethane sealant ne-silicone sealant, ixazulula ukushiyeka kwe-polysulfide sealant njengejubane eliphansi lokuphulukisa lokushisa eliphansi, ukuguga okulula nokuba lukhuni, ukuntuleka kokuqina, nephunga elinamandla eliphunga;ngesikhathi esifanayo, i-MS glue ayifani nama-silicone sealants, ungqimba olunamathelayo lujwayele ukukhiqiza i-leachate yamafutha engcolisa ukhonkolo, amatshe nezinye izinto zokuhlobisa.Inokupendeka okuhle nokuvikelwa kwemvelo, okuqhubekisela phambili ukuthuthukiswa kanye nenqubekelaphambili yama-sealant wokwakha akhiwe ngaphambilini.
Ngokuvamile, izakhiwo ezakhiwe ngaphambili ziyindlela yokuthuthukiswa kwamamodeli wokwakha.Kuwo wonke uhlelo lokwakha olwakhiwe ngaphambili, ukukhethwa kwe-sealant kuyoba enye yezixhumanisi eziyinhloko ezithinta ukuphepha kwesakhiwo sonke esakhiwe ngaphambili.I-Silicone modified polyether sealant sealant——I-MS sealant inokusebenza okuhle kakhulu okuphelele futhi kuzoba ukukhetha kwakho okuhle kakhulu.
I-SIWAY izibophezele ekuhlinzekeni amakhasimende ngezinto zokusetshenziswa ezizinzile nezithembekile zekhwalithi ephezulu kanye nezinsizakalo zobuchwepheshe ezenziwe ngokwezifiso.Ubuchwepheshe bokushintsha i-silane be-SIWAY buyaqhubeka nokuhlinzeka ngezixazululo ezichwepheshile zokutywinwa kwesakhiwo esenziwe ngaphambilini kanye nokuhlanganisa.Sibheke ngabomvu ukusebenza nawe.Ngokubambisana, sizosiza ukuthuthukiswa okunamandla kwezakhiwo ezakhiwe emhlabeni wonke .
