Material selection of Chinese made glass fin curtain wall
1. The glass exterior wall profiles should be consistent with the high precision level requirement specified in the current national standard of the aluminum alloy extruded profiles for architecture GB/T5237, anodic oxide film thickness should not be below the aa15 class specified in the aluminum and aluminum alloy anode oxidation anode oxide film of general specification GB8013.The surface color of the aluminum alloy profile is basically uniform after anodic treatment, do not allow corrosion spots, dark spots, injury, welding defects such as falling film.
2. frame supported glass fin curtainwall should adopt safety glass.The glass exterior wall with point supported by glass rib is used for theglass exteriorwall.People with large traffic, youth or children's activities in public places as well as the use of easy to be hit should use safety glass.
3.Structure adhesive has good tensile strength, peeling strength, tearing strength and elastic modulus, it also play a shockproof function.Structural silicone sealants and silicone weatherproof sealant must be provided by the supplier of materials of product quality assurance period limit proof, and compatibility of structural silicone sealant and contact materials and bonding test report, note the same batch of structural adhesive quality is stable, no more than the period of validity of the structure of silicone rubber.Weather resistant glue and structure glue can not be used as a substitute for each other, especially not to be used as a weather resistant glue.When design selected, should ask the manufacturer for the structural change of the capacity to withstand the ability of data and quality assurance.imported silicone sealant should have the inspection report.In order to ensure the engineering quality of glass fin curtain wall, with a glass fin curtain wallengineering should choose the same brand of silicone structural sealant and weather resistant glue. Not only has good compatibility, once appear quality problem occured,the responsibility is also easy to identify.
Glass exterior wall with hidden frame and semi - hidden frame.Bonded glass with aluminum must use neutral silicone sealant; full glass fin curtain wall and the point supporting glass fin curtain wall coated glass, should not use acid silicone sealant adhesive,because all the materials containing metal elements will react with acid silicone sealant lead to adhesive failure; when using non coated glass, can choose acidic structural silicone sealant.Hidden frame, semi hidden frame and point supported glass exterior wall for the two hollow glass seal must use silicone sealant.Ordinary insulating glass second seal with poly sulfur sealant UV resistant performance is poor, and not with structural silicone sealant compatibility and does not allow for the hollow glass exterior wall. Glue seam full glass fin curtain wall force, sealant must use silicone sealant.
4.Rubber seal should adopt three EPDM, chloroprene rubber or silicone rubber, comply with HG/T3099 and GB/T5574.
5.Hardware should be in accordance with the design requirements, can not use stainless steel material easy to rust, take shelter measures when welding
stainless steel to prevent the welding sparks splashed on stainless steel.
6.According to the standard requirements of A or B1 material strictly, when the fire rating of the material is not clear, should be sampled for testing.
