In the production process of insulating glass, the common problems of double sealant:

First seal:

1. When butyl rubber is extruded, burrs appear and it is not smooth.

Treatment method:

A. If it is A new machine, it should first observe whether the rubber hole is smooth, if the rubber hole is rough, it should be polished 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 is not consistent with the actual temperature, so it should be raised on the basis of the display temperature, according to a gradient of every 5 degrees until the glue is normal (Note: the temperature of the glue head should be about 5 degrees higher than the temperature of the glue cylinder).

2, butyl rubber does not stick to aluminum strip and glass

Solution:

The usual reason is that the use temperature is low, and it is recommended to increase the temperature until it is appropriate.

3, the second seal is completed, after a period of time there is a butyl glue cold flow

Solution:

This situation generally occurs in the second seal using silicone glue. The unstable quality of silicone glue is easy to migrate silicone oil out, dissolve butyl glue, and cause butyl glue to flow. It is recommended to use silicone adhesive that meets the standard quality requirements.

4, the phenomenon of breaking glue and blocking during extrusion

Solution:

This phenomenon is caused by butyl rubber does not meet 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, curing time is slow

Recommendation: The curing agent is a variable category, and the content of the curing agent should be appropriately increased until it is suitable.

2, winter mixing viscosity is large

Suggestions: Appropriately increase the construction temperature, in principle, the use of temperature is not less than 5 degrees above zero.

3, the second seal non-stick glass, low strength

Suggestion: 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 mixing. "The right medicine" can be solved.

If the product used does not meet the standard requirements, the appearance of non-stick glass and low strength is an inevitable phenomenon. Therefore, the use of substandard products should be strictly prohibited.

The problems and reasons of the finished insulating glass

1, the hollow glass inside the fog

Reason l: Due to the unstable quality of the second sealant, the content of low molecular matter is too high, and it migrates into the interior of the insulating glass under the ultraviolet irradiation of the sun, resulting in fog;

Cause 2: A seal is broken;

Reason 3: The four connecting parts are not treated with butyl glue;

Reason 4: The desiccant quality is poor, in the sunlight, the release of low molecular matter, resulting in fog.

2, hollow glass condensation

Reason 1: the molecular shoe mass is unstable and the adsorption capacity is low;

Cause 2: One or two seals fail.

Our company has a professional technical research and development team, the production of butyl spacer, butyl structural spacer, composite strip, inset strip, fireproof glass strip, two-component silicone sealant, butyl glue, high frequency welding aluminum strip, insulating glass accessories and other products have passed the inspection of Qinhuangdao National Glass quality supervision and testing Center. The company has a number of invention patents, products have passed the Chinese national mandatory product certification, EU REACH certification, EU CE certification, and passed the ISO9001 international quality management system certification for many years, to ensure product quality clearance. We must choose high-quality insulating glass when decorating, but also regularly find someone to check to ensure quality.
