Description

Technical Field

[0001] The utility model relates to the technical field of sealant performance testing, in particular to a testing component of a thermoplastic warm edge system. Background Art

[0002] Glass curtain walls have rapidly emerged in high-rise buildings and have been widely used due to their advantages such as crystal clearness, unique style, good sealing and easy maintenance. In traditional glass curtain walls, double-layer insulating glass is generally grooved aluminum insulating glass. With the proposal of green building energy conservation, warm edge insulating glass is also used on curtain walls. The warm edge spacers in warm edge insulating glass are divided into super spacers and polymer spacers. The one-piece polymer spacers have become a new material for environmentally friendly and energy-saving buildings with their low thermal conductivity and strong plasticity. However, there is currently no effective means to judge whether warm edge insulating glass can meet the technical conditions required by curtain wall glass. Therefore, the utility model proposes a test component and performs performance tests based on the prepared components to evaluate whether warm edge insulating glass can completely replace grooved aluminum insulating glass for curtain walls.

How to design a test component to determine whether thermoplastic warm edge spacers can be used for glass curtain walls, to evaluate the quality of polymer warm edge spacers, and to provide a basis for judgment for the application of warm edge spacers on curtain walls is a technical problem that needs to be solved urgently.

[0035] It should be noted that, based on the test assembly of the thermoplastic warm edge system of the present application, the following evaluation method or test method can be used to test whether the thermoplastic warm edge system is suitable for curtain wall insulating glass:

[0036] (1) First, provide the type sample 1 and type sample 2 of the utility model;

[0037] (2) The I-shaped specimen 1 and the I-shaped specimen 2 are stretched along the height direction and tested as follows:

[0038] First test:

[0039] Testing the tensile modulus of the I-type specimen 1 at an elongation of 10%; when the tensile modulus is greater than or equal to 0.15 MPa, the first test is qualified; when the tensile modulus is less than 0.15 MPa, the first test is unqualified;

[0040] Second test:

[0041] The maximum tensile strengths of the I-shaped specimen 1 and the I-shaped specimen 2 are tested respectively; when the maximum tensile strength of the I-shaped specimen 1 is greater than or equal to the maximum tensile strength of the I-shaped specimen 2, the second test is qualified; when the maximum tensile strength of the I-shaped specimen 1 is less than the maximum tensile strength of the I-shaped specimen 2, the second test is unqualified;

[0042] The third test:

[0043] Testing the damaged areas of the three bonding surfaces formed by the thermoplastic warm edge spacer 4, the first outer glue 3, the first glass 1 and the second glass 2 when the I-type specimen 1 is at the maximum tensile strength; when the damaged area accounts for less than or equal to 5% of the total area of ​​the three bonding surfaces, the third test is qualified; when the damaged area accounts for more than 5% of the total area of ​​the three bonding surfaces, the third test is unqualified;

[0045] It should be noted that in step (1), the thermoplastic warm edge spacer strip 4 and the first outer glue 3 are bonded to each other through the side, the first glass 1 is bonded to the lower surface of the thermoplastic warm edge spacer strip 4 and the first outer glue 3, and the second glass 2 is bonded to the upper surface of the thermoplastic warm edge spacer strip 4 and the first outer glue 3, and then the first glass 1, the second glass 2, the thermoplastic warm edge spacer strip 4 and the first outer glue 3 together constitute the first type sample. In the second type sample, the second outer glue 13 is also bonded to the side of the first butyl sealing strip 15 and the second butyl sealing strip 16.

[0046] It should be noted that in step (2), the I-shaped specimen 1 and the I-shaped specimen 2 are stretched along the height direction and subjected to three tests.
