Weigu glue-injection broken bridge insulation technology

The basic principle of Weigu's glue-injection broken bridge insulation technology is to divide the aluminum alloy profile into two parts, the inner and outer parts, which are connected as a whole using polyurethane insulation casting glue. By using pouring and cutting bridge methods, polyurethane insulation materials can isolate the heat conduction between the inner aluminum alloy profile and the outer layer, effectively preventing heat from transferring from warm indoors to cold outdoors. The processing method is: first, it is necessary to add a heat insulation groove when designing the profile. Then, pour the two-component heat-insulating castable glue into the heat-insulating tank in a certain proportion. Finally, after the heat-insulating casting glue reacts quickly to form a strong polymer, the temporary bridge at the bottom of the heat-insulating tank is cut off.

Reasons for choosing Weigu thermal insulation aluminum profile polyurethane thermal insulation casting glue products:

1, good heat insulation and energy saving effect

Power The Kvalue of solid polyurethane thermal insulation casting glue is0.12W/MK, the aluminum profiles produced with Weigu thermal insulation casting glue are completely sealed without seams, which can provide the best thermal insulation effect for building doors and windows.

2, excellent mechanical properties

Weigu polyurethane thermal insulation casting glue has good tensile resistance, anti-fracture and extensibility, etc. Mechanical properties,and high impact resistance, wear resistance, cutting resistance and fracture resistance.

3, Aluminum profile design is flexible and diverse, with rich window types Beautiful appearance and energy saving

Weigu polyurethane insulation casting glue technology has a relatively simple process and is There are no special requirements for aluminum profiles, the cross-section is exquisite, and the design is flexible. Aluminum doors and windows that have been processed by Weigu glue-injection heat insulation can maintain their original characteristics of rich colors, high strength, exquisiteness and beauty, while at the same time, their thermal insulation and energy-saving performance has also been greatly improved. Aluminum profiles after heat insulation treatment can be processed into various window types such as sliding, lifting, inside and outside casement, flip casement, etc. They can also be processed into special-shaped windows such as arc windows, and can also be used in curtain wall design.

4, aluminum profile production efficiency is higher span>

The production process is simple,Weigu polyurethane insulation casting glue technology completes the process of pouring, curing and bridge breaking at the same time,Suitable for large-scale and continuous production.

5, save the amount of aluminum used in aluminum profile doors, windows and curtain walls

Under the conditions of achieving the same thermal insulation effect requirements, use Weigu polyurethane insulation Compared with other types of heat-insulating aluminum profiles, the amount of aluminum profiles used for casting glue can be saved by 10%10% above. In addition, due to continuous seamless production, compared with other production methods, polyurethane insulated cast aluminum profiles can effectively reduce aluminum loss, and aluminum loss is only about 1%-2% .

6, mature technology

European technology and imported equipment ensure the consistent and stable quality of our products. The hot aluminum profile has been passed 60times, span>90times of thermal cycle tests can still meet national standards.

7, which can reduce condensation on the glass

The condensation phenomenon on the glass causes the quality of the building to be unsatisfactory. Use Weigu polyurethane for heat insulation. The pouring method can effectively reduce condensation on the glass.

8, which can ensure performance under long-term ultraviolet irradiation Unchanged

Weigu cast-in-place heat-insulating aluminum profiles are exposed to ultraviolet rays for a long time. The mechanical properties of the insulating cast glue and aluminum profiles have not changed, and the safety is not affected.

9, suitable for rainy and humid environments

Weigu polyurethane insulation casting glue is a non-water-absorbing polymer material. After being fully soaked in water, each The performance will not be reduced and is suitable for rainy weather.Use in humid environment.

10, good earthquake resistance

Weigu thermal insulation casting glue can maintain superior viscoelastic mechanical combination with aluminum profiles. And the elongation at break of the thermal insulation casting glue itself is greater than20%, which effectively ensures the use of Weigu thermal insulation The glue-cast aluminum door, window and curtain walls remain intact within a certain earthquake magnitude.

11, the performance is guaranteed in high-temperature areas

Weigu polyurethane insulation casting is a specially formulated polymer thermosetting plastic. In extreme high temperature environment (50℃) and extreme low temperature environment (-41 ℃), the mechanical properties of Weigu's insulated cast aluminum profiles can still meet the national guarantee.

12, thermal insulation casting glue is a green and environmentally friendly product

Weigu insulation aluminum profile polyurethane insulation casting glue is a green and environmentally friendly product , does not contain volatile organic compounds (VOC) and any harmful heavy metals, which will neither affect human health nor be harmful to any harm to the environment.

Weigu can provide double sets with different performance, different solidification time and different packaging according to customer requirements. Polyurethane insulation casting glue.
