Analysis of the cause of air bubbles in sealant construction
2021年08月26日
There are many reasons that cause the sealant to foam during the construction process, such as air entrapped in the glue injection; the surface temperature of the substrate is too high; the spring climate in the northern region is dry; the foam stick is deflated; The interface is wet when glueing; the temperature difference between day and night is large; the thermal expansion and contraction of the interface are large, etc., which will cause bubbles in the sealant. We need to determine the specific cause of the bubble problem and solve it.
