In the process of producing insulating glass butyl rubber, everyone knows that there are often problems. Do you know what they are?

First seal:
1. When the butyl rubber is extruded, burrs appear and are not smooth.
Approach:
A. If it is a new machine, you should first observe whether the glue holes are smooth. If the glue holes are rough, you should first polish and then try the machine;
B. If it is an old machine, because the temperature sensor of domestic equipment is sometimes insensitive, the displayed temperature does not match the actual temperature, so based on the displayed temperature, it should be adjusted up by a gradient every 5 degrees until the glue is normal (Note: (The rubber head temperature should be about 5 degrees higher than the temperature of the rubber cylinder when setting).
2.Butyl glue does not stick to aluminum strip and glass
Solution:
Usually the reason is that the use temperature is low, it is recommended to increase the temperature until it is appropriate.

     3. After the two seals are completed, a cold flow of butyl rubber appears after a period of time

     Solution:
     This situation usually occurs in the second seal using silicone glue. Unstable silicone glue can easily migrate out of the silicone oil, dissolving the butyl glue, causing the butyl glue to flow. It is recommended to use a silicone adhesive that meets the standard quality requirements.
    4.Break and blockage occurs during extrusion
    Solution:
      This phenomenon is caused by the butyl rubber not meeting the standard quality requirements and too many impurities. It is recommended to use qualified products that meet the requirements of the standard.

     Second seal:
    1.Slow vulcanization time
    Recommendation: The curing agent is a variable category, and the content of the curing agent should be appropriately increased until it is appropriate.
    2.Viscosity is high when stirring in winter
    Recommendation: Properly increase the construction temperature. In principle, the use temperature should not be less than 5 degrees Celsius.
    3. Two sealed non-stick glass, low strength
    Recommendation: If the second sealant used is a product that meets the requirements of the standard, there are two reasons for this:
   A. Excessive curing agent.
   B, uneven stirring. "Symptomatic remedy" can be resolved.
       If the product used does not meet the standard requirements, non-stick glass and low strength are inevitable. Therefore, the use of substandard products should be strictly prohibited.
