With rapid economic development in recent years, the efficient utilization of waste glass has received increasing attention. The major challenge is to improve the economic and social benefits of waste glass recycling and to improve the self-driving force of waste glass recycling in related industries. In this paper, the researchers proposed a new recycling strategy for waste glass, using low-cost waste glass powder as raw material to prepare light-weight and high-strength porous ceramic materials with self-cleaning properties by combining the emulsion template self-assembly method with a surface hydrophobic coating treatment technology. The open porosity of the prepared ceramics can be controlled at 50–70% and the ceramics have ultra-high compressive strength (i.e., 50–141 MPa). The water contact angle on its surface is as high as 162.2°, which affords remarkable anti-dirt properties, stability, and superhydrophobic performance for milk, coffee, beer, soy sauce, and other staining liquids. Moreover, the water contact angle remains unchanged at a high temperature (500 °C) and in an acid-base environment. More importantly, even if the hydrophobic coating on the surface is destroyed, the superhydrophobicity and self-cleaning ability of the ceramic materials can be restored after remodification and the reuse is excellent. Ceramic materials offer the advantages of low price, a simple process, environmental protection, and high energy efficiency, and they show great potential and broad prospects for application. At the same time, the proposed method provides a very effective way to comprehensively utilize waste glass and has remarkable economic and social benefits.

以废玻璃为原料制备自洁轻质高强度多孔陶瓷的回收利用

近年来,随着经济的快速发展,废玻璃的高效利用越来越受到重视。主要挑战是提高废玻璃回收的经济效益和社会效益,提高相关行业废玻璃回收的自驱动力。在本文中,研究人员提出了一种新的废玻璃回收策略,以低成本的废玻璃粉为原料,结合乳液模板自组装,制备具有自清洁性能的轻质高强度多孔陶瓷材料。方法采用表面疏水涂层处理技术。制备的陶瓷的开孔率可以控制在50-70%,陶瓷具有超高的抗压强度(即50-141 MPa)。其表面水接触角高达162.2°,为牛奶、咖啡、啤酒、酱油和其他染色液体提供卓越的抗污性能、稳定性和超疏水性能。此外,水接触角在高温(500°C)和酸碱环境中保持不变。更重要的是,即使表面的疏水涂层被破坏,再改性后陶瓷材料的超疏水性和自清洁能力也能恢复,重复利用性极佳。陶瓷材料具有价格低廉、工艺简单、环保、能效高等优点,具有巨大的应用潜力和广阔的前景。同时,该方法为废玻璃综合利用提供了一种非常有效的途径,具有显着的经济效益和社会效益。
