Shanghai Chuangyi Hollow Swing Glass Material Co., Ltd. is located in Jiading District, Shanghai, 2158 Jialuo Road. The company is mainly engaged in two-component silicone rubber, polysulfide rubber, butyl rubber, structural adhesive, one-component weathering adhesive, structure. front-seal plastic <br> <br>:
1. When butyl rubber is extruded, burrs appear and are not smooth.
Approach:
A. If it is a new machine, first observe whether the rubber hole is smooth. If the rubber hole is rough, it should be ground first and then try the machine;
B. If it is an old machine, because the temperature sensor of the domestic equipment is sometimes insensitive, the display temperature does not match the actual temperature, so it should be adjusted upwards every 5 degrees on the basis of the display temperature until the glue is normal (Note: When setting, the temperature of the rubber head should be about 5 degrees higher than the temperature of the rubber cylinder).
2, butyl rubber non-stick aluminum strip and glass
Treatment method:
The usual reason is that the use temperature is low, it is recommended to adjust the temperature up to the appropriate level.
3, the second seal is completed, and the butyl rubber cold flow appears after a period of time.
Treatment method:
This situation generally occurs in a two-way seal using silicone glue. Unstable silicone rubber easily migrates the silicone oil and dissolves the butyl rubber, causing the butyl gum to flow. It is recommended to use silicone glue that meets the standard quality requirements.
4. Breaking and clogging phenomenon occurs during extrusion
Treatment method:
This phenomenon is caused by butyl rubber that does not meet the standard quality requirements and too much impurities. It is recommended to use qualified products that meet the standard requirements.
Second seal:
1. Slow vulcanization time: The curing agent belongs to the variable category, and the content of curing agent should be increased appropriately until it is suitable.
2. Viscosity during mixing in winter. Suggestion: Appropriately increase the construction temperature. In principle, the temperature should not be lower than 5 degrees above zero.
3, two-way sealed non-stick glass, low strength Recommendation: If the two-way sealant used is a product that meets the standard requirements, there are two reasons for this: A, excessive curing agent, B, uneven mixing. "The right medicine" can be solved.
If the product used does not meet the standard requirements, it is inevitable that non-stick glass will appear and the strength is low. Therefore, the use of substandard products should be strictly prohibited.
Problems and causes of finished hollow glass products
1. Fogging 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 to the inside of the hollow glass under the ultraviolet light of sunlight to cause fogging;
Reason 2: A seal is destroyed;
Reason 3: The four joints were not treated with butyl rubber;
Reason 4: The desiccant is of poor quality and emits low molecular weight under sunlight, resulting in fogging.
2, hollow glass condensation
Reason l: The molecular hoof is unstable in quality and low in adsorption capacity;
Reason 2: One or two seals fail;
When we finally hit those warm summer months, shorts are unavoidable items. It is the most playful addition to your wardrobe. Whether high waisted or worn low.
