乌鲁木齐市红雁池发电厂,是一座燃煤火力发电厂,每年向外排出粉煤灰近15万吨。在这些粉煤灰中,可选出空心微珠近万吨,其中约有1500～2000吨漂珠。这种漂珠重量轻、强度好,且具有耐温、隔热、保温等多种优异性能,是制造轻质隔热保温材料的理想原料。1985年该厂自北京引进生产轻质漂珠保温砖的成套技术资料,建成了专用窑炉等成套设 The Hongyanchi Power Plant in Urumqi is a coal-fired power plant that emits nearly 150,000 tons of fly ash each year. In these fly ash, nearly 10,000 tons of hollow microspheres can be selected, including about 1,500 to 2,000 tons of floating beads. This kind of beads is light weight, good strength, and has a variety of excellent performances such as temperature resistance, heat insulation, heat preservation, etc. It is an ideal raw material for manufacturing lightweight heat insulation materials. In 1985, the plant introduced complete sets of technical data for the production of light bead insulation bricks from Beijing, and established a dedicated furnace and other sets of equipment.
