Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall testing technology, specifically a glass curtain wall abrasion resistance testing device. Background Technology

[0002] Glass curtain walls are indeed susceptible to abrasion from sand particles in dusty weather, so abrasion resistance testing is crucial. Rigorous abrasion resistance testing can ensure that glass curtain walls can withstand abrasion from sand and dust in actual use, extending their service life and also helping to protect the building's aesthetic appearance and safety.

[0003] Currently, the common testing method is the sand drop test. A certain amount of sand particles of a specific size are dropped freely from a designated height, impacting the glass curtain wall surface. After a specified number of drops, the wear on the glass surface is observed, such as the presence of scratches and the depth of wear. The wear resistance of the glass curtain wall is assessed by comparing it with a standard sample or a specified wear index. However, the kinetic energy of freely falling sand particles is relatively small, and this method cannot accurately simulate the kinetic energy of sand particles under strong winds.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] refer to Figure 1 A glass curtain wall abrasion resistance testing device includes a testing base 1, a testing placement groove 2 on the top of the testing base 1 for placing the glass to be tested, a hollow interior of the testing base 1 with a slidable and removable dust collection drawer 4 inserted inside, and multiple dust collection holes 3 in the testing placement groove 2. The testing placement groove 2 is connected to the inner cavity of the dust collection drawer 4 below through the dust collection holes 3. The glass curtain wall panel to be tested is placed in the testing placement groove 2, and then the surface of the glass curtain wall panel is sandblasted to simulate the abrasion of the glass curtain wall surface by sand and dust. The sand particles falling from the glass curtain wall during the test enter the dust collection drawer 4 through the dust collection holes 3. The dust collection drawer 4 is periodically removed and the sand particles are emptied.

[0018] The specific structure of the sandblasting is as follows: (Reference) Figure 3A gas mixing pipe 5 is installed above the test placement tank 2. Gas mixed with sand particles is introduced into the gas mixing pipe 5. Multiple sandblasting pipes 10 are connected to the bottom of the gas mixing pipe 5. The openings of the sandblasting pipes 10 face the test placement tank 2. The inner wall of the gas mixing pipe 5 is provided with a spiral guide protrusion 13. Multiple insertion holes 12 are provided on the bottom wall of the gas mixing pipe 5. The top of the sandblasting pipe 10 is inserted into the insertion hole 12. The gas mixed with sand particles generates a rotating airflow in the gas mixing pipe 5 due to the action of the guide protrusion 13. Part of the airflow enters the sandblasting pipe 10 from the insertion hole 12. The sand particles in the sandblasting pipe 10 impact the glass surface under the action of the airflow.

[0019] The mixing pipe 5 is driven by the cylinder 9 and moves back and forth in a straight line along the detection placement groove 2. The cylinder body of the cylinder 9 is fixed relative to the detection base 1, so that sandblasting can be performed on various positions of the entire glass curtain wall panel unit. Finally, the wear resistance of the glass surface is judged based on the degree of wear.

[0020] refer to Figure 2 The mixing pipe 5 is connected to the exhaust pipe 6 at both ends. One end of the exhaust pipe 6 is connected to the sand filling cylinder 7, which is connected to the air intake pipe 8. The sand filling cylinder 7 has a sand inlet on its side, and a plug 11 is screwed into the sand inlet. By opening the plug 11, sand particles can be loaded into the sand filling cylinder 7. The air intake pipe 8 and the exhaust pipe 6 are respectively connected from the top of the sand filling cylinder 7. Under the negative pressure of the airflow, the sand particles in the sand filling cylinder 7 will mix with the airflow and enter the mixing pipe 5.
