In the production process of insulating glass, the common problems are:
First seal:
1. When 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 upward 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 temperature is low. It is recommended to adjust the temperature upward to a proper level.
3. After the two seals are completed, a cold flow of butyl rubber appears after a period of time
Solution: This situation generally occurs in the second seal using silicone glue. Unstable silicone glue can easily migrate out of the silicone oil, dissolving the butyl gum, causing the butyl gum to flow. It is recommended to use silicone glue 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 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. "Remedy the symptoms" 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.
Problems and Causes of Insulating Glass Finished Products
1. Fog inside the insulating glass
Reason l: Due to the unstable quality of the two sealants, the low-molecular content is too high, and it migrates and volatilizes to the inside of the hollow glass under the ultraviolet rays of the sun, causing fogging;
Cause 2: A seal was broken;
Reason 3: The four connection parts are not treated with butyl rubber;
Reason 4: The quality of the desiccant is poor. Under sunlight, it releases low-molecular substances and causes fogging.
2.Insulating glass condensation
Reason l: The molecular sieve quality is unstable and the adsorption capacity is low;
Cause 2: One or two seals failed;
Cause 3: The four joints were not handled properly.
3. Insulating glass self-detonation
If it is a large area of tempered glass, it is a quality problem of tempered glass. It is also recommended that the glass be ground as much as possible to eliminate stress and reduce glass cracking.
