Ukwakhiwa kwe-Door ne-Window Sealant

Njengengxenye ebalulekile yezinto zokwakha zokuvala, ukusebenza kwezicabha namafasitela kuthinta ngokuqondile ukungangeni komoya, ukungangeni kwamanzi, nokuqina kweminyango namafasitela. Ukwakheka kwesayensi nokunengqondo kuqinisekisa ukuthi i-sealant inokunamathela okuhle kakhulu, ukunwebeka, nokumelana nesimo sezulu, ihlangabezana nezidingo zezindawo ezahlukahlukene.

 

Izingxenye eziyinhloko zama-sealant eminyango namafasitela zihlanganisa i-binder, fillers, plasticizers, agent elaphayo, kanye nezithasiselo. I-binder, ingxenye eyinhloko ye-sealant, ngokuvamile isebenzisa ama-polymers njenge-silicone, i-polyurethane, noma i-acrylates, futhi inquma izici eziyisisekelo ze-sealant. Izibophezelo ze-Silicone zinikeza ukumelana okuhle kakhulu kwezinga lokushisa eliphezulu neliphansi kanye nokumelana nesimo sezulu, okuzenza zifanelekele izindawo ezimbi kakhulu. Izibophezelo ze-polyurethane zinikeza ukunamathela okuqinile nokunwebeka, okuwenza afanelekele ukubekwa uphawu okuguquguqukayo. Izibophezelo ze-Acrylate zoma ngokushesha futhi zilungele ukuvala umnyango wangaphakathi nokuvalwa kwamafasitela.

Izihlungi, ezifana ne-calcium carbonate, i-carbon black, noma i-silica, zisetshenziselwa ukuthuthukisa izici zomzimba ze-sealant, ukuqinisa ubulukhuni, ukumelana nemihuzuko, nokumelana nokuncipha. Ama-Plasticizer (afana nama-phthalates) athuthukisa ukuguquguquka kwe-sealant, ayinqande ukuthi ingaqhekeki ngesikhathi sokushintshashintsha kwezinga lokushisa. Ama-ejenti okwelapha akhuthaza ukuhlangana{2}}okuxhumanisa ukusabela kuma-sealant, ukuwaguqula asuke ekubeni uketshezi aye esimweni esiqinile. Izindlela zokwelapha ezijwayelekile zifaka ukwelapha umswakama (isb., ama-silicone sealant) kanye nokwelapha ngamakhemikhali (isb., ama-polyurethane sealants).

Ukwengeza, izithasiselo ezifana nama-antioxidants, izithasiselo ze-UV, nama-ejenti e-thixotropic zingathuthukisa ukumelana nokuguga kwe-sealant nokusebenza. Ama-ejenti we Thixotropic avimbela i-sealant ekusebenzeni uma isetshenziswa ezindaweni eziqondile, iqinisekisa ukugcwaliswa okufanayo.

Kafushane, ukwakhiwa kwezivalo zeminyango namafasitela kudinga ukucatshangelwa okuphelele kohlobo lwezinto eziyisisekelo, isilinganiso sokugcwalisa, nokukhetha okungeziwe ukuze kuqinisekiswe ukunamathela okuhle kakhulu, ukunwebeka, nokuqina, okuthuthukisa ngempumelelo ukusebenza kokuvala nempilo yesevisi yeminyango namafasitela.
