AI Technical Summary
Technical Problem
Existing glass toughening processes leave stress patterns (air patterns) on the surface due to uneven air blowing, which affect the appearance and quality of toughened glass.
Method used
A curved glass toughening apparatus with a continuous flexible air grid mechanism, comprising flexible air grid units arranged in parallel and connected to main air supply pipelines, featuring fluid smoothing and airflow orienting structures to ensure uniform airflow distribution and reduce resistance.
Benefits of technology
The apparatus significantly reduces stress patterns on the glass surface, improving the appearance and quality of toughened glass by ensuring uniform cooling and airflow distribution.
