本发明属于固体废弃物资源化回收技术领域,具体涉及一种利用含有机杂质废玻璃制备超薄玻璃的方法。该方法将破碎后的含有机杂质废玻璃颗粒采用真空梯度热处理,废玻璃表面有机杂质先经过真空热解反应,形成无害化气体从废玻璃表面去除;进一步升高温度,分步使去除杂质后的废玻璃熔化液化、沸腾澄清、原位沉积,最终生成超薄玻璃;实现了废玻璃表面有机杂质绿色、高效去除和废玻璃的高附加值资源化。并且,本发明方法操作简单,无需复杂的清洗、除杂等前处理即可将含有机杂质废玻璃直接制备为高附加值超薄玻璃,非常适于产业化大规模生产。
The invention belongs to the technical field of solid waste recycling, in particular to a method for preparing ultra-thin glass by using waste glass containing organic impurities. In this method, the broken waste glass particles containing organic impurities are treated by vacuum gradient heat treatment, and the organic impurities on the surface of waste glass are first subjected to vacuum pyrolysis reaction to form harmless gas to remove from the surface of waste glass. After further increasing the temperature, the waste glass after removing impurities is melted and liquefied step by step, boiling and clarifying, in-situ deposition, and finally forming ultra-thin glass; The green and efficient removal of organic impurities from waste glass surface and high value-added recycling of waste glass are realized. Moreover, the method is simple in operation, and can directly prepare waste glass containing organic impurities into high value-added ultra-thin glass without complex cleaning, impurity removal and other pre-treatment, and is very suitable for industrial large-scale production.
