As the first seal of insulating glass, butyl adhesive plays a crucial role. The quality of the adhesive and the quality of the construction will seriously affect the performance of insulating glass. Butyl adhesive needs to be heated by a professional coating machine and applied to the aluminum frame. Many factories may experience the phenomenon of butyl adhesive breaking during the construction process. So why does this happen?
1. Improper control of glue temperature
The control of the extrusion temperature of butyl rubber is very important in the extrusion process. Whether the temperature control is appropriate will determine the rheological state of butyl rubber during construction, affecting the sealing effect of insulating glass. When the extrusion temperature is too high, it will cause excessive melting of butyl rubber, lack of strength, and even inability to form (flowing phenomenon); When the extrusion temperature is too low, the fluidity of the glue will deteriorate, the machine will not be able to extrude the glue, or it will cause blockage, resulting in problems such as glue breakage.

2. Butyl rubber contains impurities inside
In addition to machine debugging and temperature control during the glue application process, the quality of butyl rubber is also an important factor affecting the smoothness of construction. If there are impurities and bubbles inside the butyl rubber, it can also cause poor coating, resulting in problems such as glue breakage and blockage, affecting the construction progress.
The problem of butyl rubber breaking not only causes waste of material costs, but also affects the damage of coating machines, which is a problem that must be taken seriously. So how to avoid the occurrence of rubber breaking?
01
Firstly, pay attention to temperature control during construction, and set it according to the extrusion temperature range provided by the manufacturer. Generally, the temperature of the machine barrel is between 115-135 ℃.
02
The adjustment of temperature needs to be done step by step. Before applying glue, appropriate exhaust should be carried out to reduce internal air bubbles and prevent glue breakage during extrusion.
03
Choose high-quality and reliable butyl adhesive. Poor quality butyl adhesive may not only interrupt the application, but also cause problems such as wire drawing carbonization, damage the machine, and a series of quality problems during the use of insulating glass. Therefore, choosing a high-quality butyl adhesive is also the key to construction.
Every process of insulating glass should not be underestimated, and the construction of the entire sealing layer requires careful and perfect coordination in order to produce a perfect and qualified product!
