Ama-Silicone structural sealants angamelana nenani elithile lamandla, futhi izinto zokunamathisela ezimelana nesimo sezulu ze-silicone zisetshenziselwa kakhulu ukuvala uphawu olungangeni manzi. I-Silicone structural adhesive ingasetshenziselwa ozimele abancane futhi ingamelana nokushuba okuthile namandla adonsela phansi. Ingcina ye-silicone emelana nesimo sezulu isetshenziselwa kuphela i-caulking futhi ayikwazi ukusetshenziselwa ukuvala uphawu kwesakhiwo.
I-Silicone Building Sealant iyisivali esinekhwalithi ephezulu eselaphayo sekhwalithi ephezulu ye-silicone. Ukumelana nesimo sezulu esihle kakhulu, ukumelana nokushisa okuphakeme nokuphansi -50°C+150°C, ukunamathela okuhle, kungakhushulwa futhi kusetshenziswe ezinhlobonhlobo zezimo zezulu, futhi kusabela ngokushesha ngomswakama emoyeni, kwelaphe endaweni ehlala isikhathi eside, Ephakeme. ukusebenza kanye ne-elastic silicone sealant, ingamelana nokuguguleka kwemvelo okufana nomoya-mpilo nephunga, imisebe ye-ultraviolet nemvula. Ikakhulukazi esetshenziselwa ukukhwabanisa nokuvala iminyango, amafasitela kanye nomhlobiso wezakhiwo.
Phakathi kwezinkomba zobuchwepheshe eziyinhloko zama-silicone ukumelana nesimo sezulu, ukucwila, ukunwebeka, kanye nesikhathi sokumisa phezulu kubonisa ukusebenza kokwakha. Ukusebenza kwe-sealant eselashiwe ukumelana nesimo sezulu ikakhulukazi amandla okususwa kanye nezinga lokulahlekelwa okukhulu. Izinga lokulahlekelwa okukhulu kwezinamatheliso ezimelana nesimo sezulu lilingana nokuncipha kwesisindo esishisayo sezinamatheliso zesakhiwo. Ikakhulukazi ukuphenya izinguquko zokusebenza kwezinamathelisi ezimelana nesimo sezulu ngemva kokusetshenziswa isikhathi eside. Uma izinga lokulahlekelwa okukhulu liphezulu, ukusebenza kwehle kakhulu ngemva kokusetshenziswa isikhathi eside.
Umsebenzi oyinhloko we-silicone ukumelana nesimo sezulu ukuvala amalunga phakathi kwamapuleti. Njengoba amapuleti evame ukuthinteka ekushintsheni kwezinga lokushisa kanye nokuguqulwa kwesakhiwo esiyinhloko, ububanzi obuhlangene buzobuye bushintshe. Lokhu kudinga i-adhesive ukumelana nesimo sezulu ukuze ibe nekhono elihle lokumelana nokuhamba ngokuhlanganyela, futhi ngeke iqhekeke ngaphansi kwesimo sezinguquko zesikhathi eside kububanzi obuhlangene. ezahlukene.
I-Silicone Structural Sealant iyingxenye eyodwa, yokwelapha engathathi hlangothi, eklanyelwe ngokukhethekile ukuhlanganisa izakhiwo zengilazi ekwakheni izindonga zamakhethini. Ingakhishwa kalula futhi isetshenziswe ezinhlobonhlobo zezimo zokushisa. Thembela kumswakama osemoyeni ukuze welaphe ube yimodulus ephezulu ehlala isikhathi eside, irabha ye-silicone enwebeka kakhulu. Umkhiqizo awudingi i-primer engilazini, futhi ungakhiqiza ukunamathela okuhle kakhulu.
I-adhesive yesakhiwo isho amandla aphezulu (amandla acindezelayo> 65MPa, amandla e-steel-steel positive tensile bonding> 30MPa, shear strength> 18MPa), ingamelana nemithwalo emikhulu, futhi imelana nokuguga, ukukhathala, ukugqwala, nokusebenza ngaphakathi kwempilo elindelekile. Izinzile, ifanele ukuhlangana okuqinile kwesakhiwo. Izinamatheliso ezingezona ezakhiwe zinamandla aphansi futhi azihlali ziqinile, futhi zingasetshenziselwa kuphela ukubopha, ukuvala uphawu nokulungisa izakhiwo ezivamile nezesikhashana, futhi azikwazi ukusetshenziselwa ukuhlanganisa izakhiwo.
