【摘要】：能源的巨大需求造成了全球资源的过度消耗，同时产生了大量的废弃物，增加了环境负担。如何在改善环境的基础上有效的处理并利用废弃物是当前研究的热点。为了减少向空气中排放二氧化硫的含量，燃煤电厂采用脱硫工艺势在必行，由此不可避免的产生了一种工业废物，，即脱硫石膏，它的某些性能优于天然石膏，是天然石膏的潜在替代品。处理后的脱硫石膏作为一种新型环境功能材料，越来越受到人们的关注，但却一直与艺术设计无关。 本文利用牡丹江第二发电厂烟气脱硫产生的废料——脱硫石膏作为原料，通过热处理使脱硫石膏性产生活性。研究成果表明：通过热处理可以得到以半水石膏为主的低碳装饰材料，热处理温度与时间均对脱硫半水石膏的转化率和强度有较大影响。最佳的煅烧温度为180℃，最佳的煅烧时间为1.5h，在该条件下，脱硫石膏的转化率最高，强度最大。制得的材料内部结构呈多孔状，可作为装饰材料使用，以达到环保和节约资源的目的。 本文以脱硫半水石膏替代天然石膏，利用脱硫半水石膏材料节能环保、经济实用成本低、取材丰富便捷、成型工艺简单等优点，将其运用到室内装饰陈设的设计中，以达到材料与环境的和谐统一。设计制作了陈设装饰品、浮雕壁挂、佛头石膏像等脱硫半水石膏材料室内装饰陈设品，不仅其本色古朴自然，而且添加色料或表面粉饰后，能够仿造其他材料的颜色和质感，其装饰效果不亚于其他材质，达到了功能性与装饰性、生态性与可持续性、感性与理性有机融合的艺术效果，可广泛应用于室内装修。是低碳装饰材料与艺术设计的完美结合。同时为脱硫石膏材料的发展与设计应用提供了范例。
[Abstract]:The huge demand for energy causes the excessive consumption of global resources, at the same time produces a large amount of waste, and increases the environmental burden. How to effectively dispose and utilize wastes on the basis of improving environment is a hot topic. In order to reduce the emission of sulfur dioxide into the air, it is imperative for coal-fired power plants to adopt desulphurization technology, which inevitably produces a kind of industrial waste, that is, desulphurized gypsum, and some of its properties are superior to those of natural gypsum. Is a potential substitute for natural gypsum. As a new type of environmental functional material, the treated desulphurized gypsum has attracted more and more attention, but it has nothing to do with art design. In this paper, the desulphurization gypsum produced by flue gas desulphurization in Mudanjiang No. 2 Power Plant is used as raw material, and the activity of desulphurization gypsum is produced by heat treatment. The results show that the low carbon decorative materials mainly composed of hemihydrate gypsum can be obtained by heat treatment, and the heat treatment temperature and time have great influence on the conversion and strength of desulphurized gypsum. The optimum calcination temperature is 180 鈩
