Car Windshield Recycling Machine
The glass components of the windshield and the interlayer can be fully separated using a glass pre-pressing machine and a glass detachment machine, resulting in the extraction of pure glass and the PVB/SGP/EVA interlayer materials.
Introduction：
Car Windshield Recycling Machine can be used for the separation of pure glass and the PVB/SGP/EVA interlayer materials from waste Windshield.
Car windshields are composed of two layers of flat glass, with one or more layers of PVB (polyvinyl butyral) sandwiched between them. The higher-quality PVB used in automotive laminated glass can be recovered and holds significant recycling value when replaced in the scrap car disassembly and maintenance market. Our company has designed a specialized waste car laminated glass separator, a piece of equipment tailored for the effective separation of glass from laminated glass. This equipment is widely employed in the recycling, processing, and reuse of waste car windshields, significantly enhancing the recovery value of the materials involved.
How to work:
firstly, The glass and PVB layer can be separated initially by roller press.
The roller press mainly applies pressure to the windshield of an old car through a pair of rollers rotating opposite each other. When the laminated glass passes through the gap between the rolls, due to the extrusion of the rolls, the glass and the PVB (polyvinyl butyral) adhesive layer in the middle will be deformed to a certain extent. For some parts that are not particularly tightly bonded, this extrusion can initially separate the glass and adhesive layer.
Primary treatment function: It is the front end of the entire recycling process and is able to perform the initial physical processing of the used windscreen. For example, it can break a larger size windshield and turn it into smaller glass fragments that are easier to handle later, reducing the volume of glass fragments and facilitating subsequent transportation and further processing. ◦ Partial separation: For the glass and PVB adhesive layer in the laminated glass, the roller press can loosen the bond between the two, and achieve the separation of the glass and adhesive layer to a certain extent, improving the separation efficiency.
2.On the basis of the preliminary treatment of the roller press, the separator can more accurately separate the glass and PVB adhesive layer completely, and obtain a more pure glass and adhesive layer product.
For example, after the separator treatment, the glass can reach a high purity and can be directly used in the production of glass recycled products; The PVB adhesive layer can also be recycled for other applications, such as making new adhesive materials. ◦ Improved recycling quality: Through fine separation, the quality and value of recycled materials can be improved. For example, high-quality recycled glass can be used to manufacture high-quality glass products, such as architectural glass, automotive glass, etc. The pure PVB adhesive layer can be reprocessed into a standard adhesive material, reducing production costs.
3.All of these materials hold significant value. Approximately 1 ton of PVB film can be extracted from 10 tons of automotive windshields, representing a 10% yield. The glass pre-pressing machine is capable of crushing laminated glass, such as that found in car windshields, followed by a three-day water soak before the glass and interlayer are separated through a separator machine.
