What is the principle of applying film to the dust removal chamber? Where is it better than manual pasting?

A: The dust removal chamber (also known as the dust-free chamber/second application chamber) is an auxiliary film application tool. It is usually a plastic frame that matches the size of the mobile phone, with built-in dust removal stickers and positioning structures inside. Principle: ① Place the mobile phone in the dust removal chamber, and precisely align the chamber with the screen position; ② The dust on the screen surface is adhered away before the film is applied by the dust-removing stickers (silicone or electrostatic adsorption) inside the warehouse. ③ The film is pre-fixed on the warehouse body. After pulling down the release film, it automatically and precisely adheres, reducing hand shake and alignment deviation. Where it is better than manual pasting: ① Reduce dust: Closed environment + dust-removing stickers, significantly reducing the bubbles caused by dust entering; ② Precise alignment: The warehouse body is precisely positioned and will not be misaligned. ③ Simple operation: Even beginners in applying films can succeed on the first try. ④ Reduce fingerprints: Hands do not directly touch the film surface.
