七十年代,英国人在火力发电厂的储灰池水面上收集到空心微珠,其含量约占粉煤灰的20％(体积),这一发现,结束了人工合成空心微珠因价格昂贵而难以在轻质耐火材料上推广应用的局面。并开辟了工业废渣粉煤灰更高层次综合利用的光明前景。一九八0年,国家科委在三年重点科研项目中给济宁发电厂下达了漂珠应用试验的科研课题任务。我国对漂珠性能和应用的研究始于七十年代末,八十年代初。
Seventies, the British people in the thermal power plant ash pool water collected hollow beads, the content of about 20% (volume) of fly ash, the discovery, the end of synthetic hollow beads due to expensive It is difficult to popularize the application of lightweight refractory materials. And opened up a bright future for the comprehensive utilization of industrial waste fly ash at a higher level. In 1980, the State Science and Technology Commission issued a task of scientific research on floating beads application test to Jining Power Plant in three years of key scientific research projects. Our study on the performance and application of floating beads began in the late seventies and early eighties.
