Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive paint protection film testing technology, and in particular to a device for testing the repair capability of automotive paint protection film. Background Technology
[0002] Paint protection film (PPF) is a high-performance, new type of environmentally friendly film widely used in the automotive detailing and maintenance industry. It's a common name for transparent paint protection film. It boasts superior toughness and, once applied, isolates the car's paint from the air, providing long-lasting protection. PPF is a thermoplastic polyurethane film (TPU) containing UV-resistant polymers, preventing yellowing. It possesses exceptional toughness, is abrasion-resistant, does not yellow, is easy to apply, and resists collisions and scratches. After application, it isolates the car's paint from the air, protecting against acid rain, oxidation, and scratches.
[0003] A patent search revealed a device for testing the repair capability of paint protection film (PPF) using patent number CN217033467U. This device uses a scraper to test the repair capability by placing PPF at a specific location on a tabletop. Drive mechanisms on either side of the tabletop move the frame of the entire device: a slider on the surface of a telescopic rod is controlled by a telescopic rod seat, thus controlling the frame's movement. The core advantage of this device is that a spring connected to a pressure sensor connects to the scraper. A cylinder at the top controls the scraper at the bottom to scrape the PPF surface, and the pressure sensor and spring control the scraping stress of the scraper at the end face, thus achieving scraping effects under different stresses. This device's stress detection directly detects PPF under different stresses, superior to existing PPF testing devices. However, this device only tests for scratch pressure and lacks auxiliary repair equipment. The self-repair function of PPF typically requires certain temperature conditions to trigger; the lack of heating equipment means the test only reflects scratch damage and cannot verify the repair effect of the PPF in actual use.
[0004] Therefore, those skilled in the art have provided a device for testing the repair capability of automotive invisible paint protection film to solve the problems mentioned in the background art. Utility Model Content
