Bonding technique of fluorocarbon coating and structural adhesive for glass curtain wall
Glass curtain wall maintenance has become an important maintenance project of glass curtain wall engineering, and sealant is the key to ensure that the curtain wall glass is effectively sealed and ensure the quality of the project, so today, yiminghua curtain wall ribbon takes you to understand the bonding skills of fluorocarbon coating and structural adhesive, so as to help you do a better job in the bonding of fluorocarbon coating and structural adhesive of glass curtain wall!
Fluorocarbon coating and structural adhesive bonding of glass curtain wall
Why should we pay attention to the bonding of structural sealant and fluorocarbon coating?
Because the glass curtain wall is the key project in curtain wall engineering, the sealing performance, heat preservation and cold resistance are affected by sealant, but in real life, the bonding of some structural sealant and fluorocarbon coating can not meet the requirements of curtain wall, so measures should be taken to improve the sealing force between the sub frame and glass of hidden frame curtain wall glass components, and the joints between fluorocarbon coated panels. Therefore, if you want to do a good job in glass curtain wall engineering, you must know the bonding skills of glass sealant!
What are the effective measures for the bonding of structural sealant and fluorocarbon coating?
Here, we recommend four common effective measures to help you solve the bonding problem of structural sealant and fluorocarbon coating.
(1) However, some experts believe that this method is not reliable and belongs to "two-layer skin", and there is no convincing positive report to prove that this method is effective, so it needs further observation and research;
(2) The structure of composite profiles is adopted, the part of structural adhesive directly bonded is separated from other parts of profiles, and the part of structural adhesive directly bonded is anodized;
(3) In the process of fluorocarbon spraying, the parts to be bonded are covered to keep the surface anodized;
(4) Take remedial measures, remove the coating on the surface to be bonded with sandpaper, etc., and rely on natural oxidation (about 5 μ m)。
It is necessary to deal with the details of the seemingly detailed things, especially during the operation, to ensure that the curtain wall glass is effectively pasted without bubbles or dust entering, so as to avoid the opening and bulging of the curtain wall glass sealant.
