Description

Technical Field

[0001] The utility model relates to the technical field of PVB film production, in particular to a PVB milky white film adhesion testing device. Background Art

[0002] PVB (polyvinyl acetate butyrate) is a polymer material commonly used in the manufacture of laminated glass to increase the strength and safety of glass. When producing laminated glass, the viscosity of PVB film is an important quality control parameter. Viscosity represents the resistance of the fluid, which is crucial to ensure the uniformity and performance of laminated glass. Therefore, the adhesion of PVB film needs to be tested during its production and processing. In addition to the existing viscometer for testing PVB film, there is also a later impact test on the processed glass to observe the breakage of the glass to determine the adhesion of the PVN film in the glass interlayer.

[0003] However, in the existing impact test process, there are the following deficiencies:

[0004] (1) Since there is no corresponding mechanism to fix the glass, the glass is often placed flat on the table or tilted against the wall during the impact test. This makes it impossible to simulate the normal vertical installation state of the glass, which will affect the subsequent judgment of the adhesion of the PVN film;

[0005] (2) During the impact test, workers generally only wear gloves and goggles for protection. However, during the impact test, glass will be broken by force and glass fragments will fly. Only gloves and goggles cannot avoid the damage caused by glass fragments.

[0006] (3) After the impact test, glass fragments will be scattered all over the floor, which requires staff to clean up and collect them after the test, greatly increasing the workload of staff;

[0007] Therefore, a PVB milky film adhesion testing device that can overcome the above-mentioned defect is badly needed. Utility Model Content

[0008] In order to overcome the deficiencies in the background technology, the utility model discloses a PVB milky white film adhesion testing device.

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0029] Please refer to the instruction manual Figure 1-6 , the utility model provides a technical solution:

[0030] Embodiment 1, a PVB milky film adhesion test device, including a collecting tank 6, both ends of the upper notch of the collecting tank 6 are provided with vertical plates 1, the two vertical plates 1 are arranged with opposite and parallel surfaces, a support rod 5 located at the upper notch of the collecting tank 6 is provided at the lower part between the two vertical plates 1, and a movable rod 2 corresponding to the support rod 5 and capable of lifting and lowering is provided at the upper part between the two vertical plates 1. Specifically, a slide groove 9 arranged along the height direction of the vertical plates 1 is provided on the opposite surfaces of the two vertical plates 1, and sliders 11 slidably matched with the slide groove 9 are provided at both ends of the movable rod 2. A placement groove 4 for limiting the placement of glass is provided on the opposite surfaces of the support rod 5 and the movable rod 2. When placing the test glass, it is only necessary to first place the lower edge of the test glass into the placement groove 4 on the support rod 5, and then slide the movable rod 2 downward along the slide groove 9, so that the placement groove 4 on the lower surface of the movable rod 2 is engaged with the upper edge of the test glass, thereby completing the vertical placement of the test glass;

[0031] A shielding member 3 is also provided between the two upright plates 1 and located on the same side of the plate surfaces of the two upright plates 1. The shielding member 3 includes a storage tube 14 and a pull-out rod 12. The storage tube 14 is installed on the upper or lower part of the same side of the two upright plates 1, and the storage tube 14 can be fixed by plugging or screwing.
