摘要
采用丝网印刷技术,以天然电气石粉末为原料成功制备了镁电气石/玻璃复合材料与锂电气石/玻璃复合材料,并在密闭空间测量了电气石/玻璃复合材料的负离子释放性能。负离子测试结果表明,当镁电气石/玻璃复合材料与锂电气石/玻璃复合材料的附着面积为76.97 cm^(2)时,负离子释放量分别为202 cm^(-3)和208 cm^(-3),说明镁与锂电气石/玻璃复合材料的负离子释放性能近似,廉价镁电气石可以替代价格昂贵的锂电气石用于制备具有负离子释放性能的玻璃材料。进一步研究发现,当电气石粉末附着面积增加一倍时,镁与锂电气石/玻璃复合材料负离子释放量均提高为原来的3倍左右。
In this study,the Mg tourmaline/glass composites and Li tourmaline/glass composites were prepared by screen printing technology,in which the mixture of the grinded tourmaline powder and glaze with the weight ratio of 1:5 were first calcined at 500℃for 12 h and then quenched by strong wind to room temperature.The negative ion release property results indicated that Mg tourmaline/glass composites and Li tourmaline/glass composites are similar,where the mean value of negative ion is 202 cm^(-3)and 208 cm^(-3)respectively when the attachable area is 76.97 cm^(3).Thus,the expensive Li tourmaline can be replaced by the cheap Mg tourmaline.When the attachable area of tourmaline powder is doubled,the negative ion release values of Mg tourmaline/glass composites and Li tourmaline/glass composites are increased by 3 times.
