In the past decade, China's laminated glass industry has achieved comprehensive empowerment from safety protection to 'safety+energy saving+intelligence+green' through three major technological innovation paths: material innovation, process upgrading, and functional expansion, promoting the industry towards high-quality development. Breaking through the core bottleneck on the material side, the localization rate of nano modified PVB intermediate film has reached 65%, the bending strength of SGP ion type film has been increased by 5 times to traditional products, and the problem of delamination and foaming in humid and hot environments has been overcome; North Glass has independently developed aviation grade PVB sandwich technology that can withstand typhoons of level 12 and is suitable for super high-rise buildings and transportation hubs. The digital transformation of the process is accelerating, and the fully automatic interlayer pressing furnace achieves a surface accuracy of ± 0.1mm. AI visual quality inspection stabilizes the yield rate at over 95%, reduces energy consumption by 30% compared to ten years ago, and increases the efficiency of a single production line by 300%. Functional integration has given rise to high value-added products, with electrochromic laminated glass suitable for green buildings, photovoltaic integrated (BIPV) laminated glass achieving a three in one 'power generation safety transparency', new energy vehicle windshields integrating HUD projection and infrared reflection functions, and rail transit specific glass improving impact resistance by 40%. The application scenarios have expanded from building curtain walls to new energy, military and other fields. By 2024, the proportion of functional products will reach 42%, an increase of 23 percentage points from 2018. South Glass's 'zero carbon laminated glass' has a winning rate of 76.4% in projects such as Xiong'an New Area, becoming a typical paradigm for traditional industries to transform into high-end manufacturing.
