The deformation of aluminum strip
Situation: The aluminum strips are twisted and the surface are not smooth due to the production process problem. This kind of unevenness will affects the width of the aluminum strip. And in the process of coating butyl sealant, some places will have no substantial adhesion between the butyl sealant and aluminum strip.
Solution: For this problem, inspection during frame production process will be helped. When the situation is serious, it will affects the normal operation of the butyl sealant machine.
Because of the low water vapor transmission rate, butyl sealant becomes the guarantee of the sealing of hollow products. But if aluminum strip is not working well together with the butyl sealant, the sealing effect will be not ensured.
