Structural Sealant hman dan tur tehfung hrang hrang thlirletna

Structural sealants hi building, bridge leh project dang hrang hranga connection leh sealing atana hmanraw pawimawh tak a ni. An performance hian structural safety leh durability a nghawng nghal vek a ni. Product quality leh application rintlakna tur atan ram chhung leh ram pawnah implementation standard khauh tak siam a ni a, material property, testing method, leh application specification te a huam a ni.

 

China ramah chuan structural sealant hmanna tur standard bulpui ber chu GB 16776-2005, "Silicone Structural Sealant for Construction" tih a ni. He standard hian silicone structural sealants te classification, technical requirements, test methods, leh inspection rules te a tarlang a, chiang takin key indicator tensile bond strength, displacement capacity, leh aging resistance te hian value tarlan te a tlin a ngai a ni. Entirnan, standard chuan silicone structural sealants te hian ni 28 chhunga tensile bond strength 0.6 MPa aia tlem lo a nei tur a ni a, durability test, heat aging leh UV exposure te pawh a paltlang tur a ni tih a tarlang. Chubakah, GB/T 14683-2017, "Silicone Building Sealant," hi non-structural application atana sealant-te tan hman a ni a, GB 16776 a tihlawhtling bawk.

International lamah chuan ASTM C1184, "Standard Specification for Structural Silicone Sealant," leh ETAG 002, "Structural Sealant Assembly Systems atana Technical Approval Guide" te hi reference standard hriat hlawh tak an ni. ASTM C1184 hian silicone sealants modulus, elongation, leh adhesion atana thil tul chipchiar tak a siam a, ETAG 002 hian curtain wall assembly system-te himna zawng zawng tehna a ngaihtuah a, hun rei tak-term performance verification a ngaih pawimawh hle thung.

Heng standard-te khauh taka kalpui a nih chuan structural sealants quality mumal tak a awm theih nan a pui mai bakah engineering design atan pawh a bulpui rintlak tak a siam bawk. Nakin lawkah chuan materials science lama hmasawnna a awm chuan, a kaihhnawih standard te chu a tha zawka siam chhunzawm zel a ni ang a, chu chu performance sang zawk leh environment mamawhna nei application mamawh phuhruk a ni ang.
