AI Technical Summary
The existing curing process for coated tempered glass is prone to uneven heating, warping and deformation, low production efficiency, high energy consumption, and insufficient cross-linking of ordinary silicon-based coating solutions, resulting in a low grafting rate of hydrophobic groups.
A two-stage stepped curing process is adopted, combined with a modified coating solution. The bottom film is pre-cured at low temperature in the first curing oven and the surface film is rapidly cross-linked at high temperature in the second curing oven. With the help of PID control and centrifugal exhaust, thermal stress accumulation and film defects are avoided.
It achieves uniform heating and rapid curing of glass, reduces the risk of warping, improves production efficiency and the density and durability of the film, and reduces energy consumption and film defects.
