machine de recyclage de pare-brise de voiture en verre stratifié

Automotive windshields, a typical example of laminated glass, utilize a sandwich structure of glass, PVB film, and glass. The PVB interlayer typically has a thickness of 0.38-1.52mm and accounts for 3-5% of the total glass weight. While this unique structure improves safety, it also presents challenges for recycling, making effective material separation difficult using traditional methods.

The intelligent laminated glass separation system consists of a preheating device, a precision cutting machine, a thermal decomposition unit, and a material sorting module. Its innovative process includes: glass pretreatment → precise temperature-controlled heating (180-220°C) → PVB film softening and separation → automatic material sorting. The latest equipment utilizes infrared temperature control technology, achieving a separation efficiency exceeding 95%, capable of processing 2-3 tons of discarded windshields per hour.

Professional recycling yields high-purity glass granules and intact PVB film. The glass can be directly used in new glass manufacturing, while the PVB film can be processed for applications such as road markings. Data shows that each ton of recycled windshields generates approximately 1,500 yuan in economic value, more than ten times the value of traditional landfilling.

This technology has increased the automotive glass recycling rate from less than 20% to over 85%. A single production line can process up to 5,000 tons annually, reducing carbon emissions by 3,000 tons. With the increasing popularity of new energy vehicles, market demand for this equipment is rapidly growing, with the market size projected to exceed 5 billion yuan by 2025, making it a key supporting technology for the circular economy.
