钛石膏资源化利用的研究进展与发展建议

Research Progress and Development Suggestion on Resource Utilization of Titanium Gypsum

这是一篇冶金工程领域的论文。钛石膏是采用硫酸法生产钛白粉时产生的以二水硫酸钙为主要成分的工业废渣。钛石膏因其杂质含量高、脱水困难、后续产品力学性能差等因素目前资源化利用率较低。大量露天堆存的钛石膏给钛白粉企业造成了极大的环保与经济压力,也是对土地资源的严重浪费。本文总结了目前国内外钛石膏在建材、化工、农业及应对气候变化等方面的利用现状和研究进展,并从产品结构调整、技术革新与绿色发展、标准制定与政策扶持等方面对钛石膏的有效减量及高质量资源化提出了建议与展望。

This is an article in the field of metallurgical engineering.Titanium gypsum is an industrial waste residue mainly composed of calcium sulfate dehydrate when the titanium dioxide is produced by the sulfuric acid method.At present,the utilization rate of titanium gypsum is relatively low due to its high impurity content,difficulty in dehydration and poor mechanical properties of the subsequent products.A large amount of titanium gypsum stored in the open air has caused great environmental and economic stress on the titanium dioxide enterprises,which is a serious waste of land resources.In this article,the current situation and research progress of global titanium gypsum in building materials,chemical industry,agriculture and climate change were summarized.The suggestions and prospects for the effective reduction and high-quality resource utilization of titanium gypsum from the aspects of structure adjustment,technological innovation,green development,standard formulation and policy support were provided.
