Uhlahlelo lweMigangatho yokuSetyenziswa kwe-Structural Sealant

Izitywini zesakhiwo zizinto eziphambili zokudityaniswa kunye nokutywinwa kwizakhiwo, iibhulorho, kunye nezinye iiprojekthi. Ukusebenza kwazo kuchaphazela ngqo ukhuseleko lwesakhiwo kunye nokuqina. Ukuqinisekisa umgangatho wemveliso kunye nokuthembeka kwesicelo, imigangatho yokuphunyezwa engqongqo iye yasekwa zombini ngaphakathi nangaphandle, igubungela iipropati eziphathekayo, iindlela zokuvavanya, kunye neenkcukacha zesicelo.

 

E-China, umgangatho ophambili wokuphunyezwa kwee-sealants zesakhiwo yi-GB 16776{7}}2005, "I-Silicone Structural Sealant yoKwakha." Lo mgangatho uxela ulwahlulo, iimfuno zobugcisa, iindlela zovavanyo, kunye nemithetho yokuhlola ii-silicone structural sealants, kwaye ifuna ngokucacileyo ukuba izalathisi eziphambili ezinje ngokuqina kwebhondi, umthamo wokufuduka, kunye nokumelana nokwaluphala kuhlangane namaxabiso achaziweyo. Umzekelo, umgangatho umisela ukuba ii-silicone structural sealants kufuneka zibe ne-28-day tensile bond force engekho ngaphantsi kwe-0.6 MPa kwaye kufuneka baphumelele iimvavanyo zokuqina ezifana nokuguga kobushushu kunye nokuvezwa kwe-UV. Ngaphezu koko, i-GB/T 14683-2017, "I-Silicone Building Sealant," isebenza kwii-sealants zezicelo ezingezizo zesakhiwo kunye nokuncedisa i-GB 16776.

Ngamazwe ngamazwe, i-ASTM C1184, "iNkcazelo eMiselweyo yeSilicone seSilicone seSialant," kunye ne-ETAG 002, "IsiKhokelo sokuVunywa kweTechnical for Structural Sealant Assembly Systems," yimigangatho eyamkelwa ngokubanzi. I-ASTM C1184 ibeka iimfuno ezineenkcukacha zemodyuli, i-elongation, kunye ne-adhesion ye-silicone sealants, ngelixa i-ETAG 002 igxile kuvavanyo olupheleleyo lokhuseleko lweenkqubo zokuhlanganisa udonga lwamakhethini, igxininisa ukuqinisekiswa kokusebenza kwexesha elide.

Ukuphunyezwa ngokungqongqo kwale migangatho akuqinisekisi kuphela umgangatho ongaguqukiyo wee-sealants zesakhiwo kodwa kwakhona kunika isiseko esithembekileyo soyilo lobunjineli. Kwixesha elizayo, kunye nenkqubela phambili kwisayensi yezinto, imigangatho efanelekileyo iya kuqhubeka iphuculwa ukuhlangabezana neemfuno zezicelo kunye nokusebenza okuphezulu kunye neemfuno zokusingqongileyo.
