Ukuhlaziywa Kwamazinga Okusetshenziswa Kwe-Structural Sealant

Ama-sealant esakhiwo ayizinto ezibalulekile zokuxhuma nokuvala ezakhiweni, amabhuloho, nakwamanye amaphrojekthi. Ukusebenza kwazo kunomthelela ngqo ekuphepheni kwesakhiwo kanye nokuqina. Ukuqinisekisa ikhwalithi yomkhiqizo nokuthembeka kohlelo lokusebenza, kuye kwasungulwa amazinga aqinile okusebenza ngaphakathi nangaphandle, ahlanganisa izakhiwo zezinto ezibonakalayo, izindlela zokuhlola, kanye nokucaciswa kwesicelo.

 

E-China, izinga eliyinhloko elisetshenziswayo lama-sealant esakhiwo i-GB 16776{7}}2005, "I-Silicone Structural Sealant Yokwakha." Leli zinga licacisa ukuhlukaniswa, izidingo zobuchwepheshe, izindlela zokuhlola, nemithetho yokuhlola yama-silicone structural sealant, futhi idinga ngokusobala ukuthi izinkomba ezibalulekile ezifana namandla ebhondi eqinile, umthamo wokufuduka, nokumelana nokuguga kuhlangabezane namanani acacisiwe. Isibonelo, indinganiso ibeka ukuthi ama-silicone structural sealant kufanele abe namandla ebhondi eqinile yezinsuku ezingama-28 angekho ngaphansi kuka-0.6 MPa futhi kufanele aphumelele ukuhlolwa kokuqina okufana nokuguga kokushisa nokuchayeka kwe-UV. Ngaphezu kwalokho, i-GB/T 14683-2017, "I-Silicone Building Sealant," isebenza kuma-sealant wezinhlelo zokusebenza ezingezona ezesakhiwo futhi ihambisana ne-GB 16776.

Emazweni ngamazwe, i-ASTM C1184, "Ukucaciswa Okujwayelekile Kwe-Structural Silicone Sealant," kanye ne-ETAG 002, "Umhlahlandlela Wokuvunyelwa Kobuchwepheshe Wezinhlelo Zomhlangano Zokuvala Izinsimbi," kungamazinga aqashelwa kabanzi. I-ASTM C1184 isetha izidingo ezinemininingwane ze-modulus, elongation, kanye nokunamathela kwama-silicone sealant, kuyilapho i-ETAG 002 igxile ekuhlolweni kokuphepha kukonke kwamasistimu wokuhlanganisa amakhethini, egcizelela{5}}ukuqinisekiswa kokusebenza kwesikhathi eside.

Ukuqaliswa okuqinile kwalawa mazinga akuqinisekisi nje kuphela ikhwalithi engaguquki yama-sealant esakhiwo kodwa futhi kunikeza isisekelo esithembekile sokuklama kobunjiniyela. Ngokuzayo, ngokuthuthuka kwesayensi yezinto zokwakha, izindinganiso ezifanele zizoqhubeka nokuthuthukiswa ukuze zihlangabezane nezidingo zezinhlelo zokusebenza ngokusebenza okuphezulu kanye nezidingo zemvelo.
