The implementation drawn, its yield is also by the lasting rising with the continuous construction of flue gas desulfurization device.Building material industrial technology information
Director of the Institute Xu Luoyi is pointed out in 2014 annual desulfurated plaster utilization obstacles discuss forum：" China is coal mining and fire
Power generating big country, desulfurated plaster discharge capacity is huge, and the utilization rate of current desulfurated plaster is mainly used in building at present 70% or so
Building material industry, such as cement retarder, plaster of Paris, Thistle board, brushing gypsum.From the point of view of the whole country, utilized actual
During, exist as follows with urgent problem to be solved：(1) as interior coal-burning power plant side, based on flue gas desulphuization rate index, lack
Be dried to flue gas ash removal, to aqueous powdery desulfurated plaster, the technique Journal of Sex Research of calcined dehydration, it is and complete to desulfurated plaster
Understanding and control new technology, new technology lack；(2) as desulfurated plaster comprehensive utilization side, lack the corresponding regulation of desulfurated plaster,
Under policy, standard and the environmentally friendly attitude towards sex of recycling, it is confined to cement retarder, plaster of Paris, paper in traditional construction material industry
Plasterboard, answering for brushing gypsum are mixed or substituted, and cause the comprehensive utilization of desulfurated plaster to show low side added value, scattered shakiness
It is fixed, using it is insufficient the problem of.(3) interior coal-burning power plant side, desulfurated plaster comprehensive utilization side are to desulfurated plaster product technology, desulfurization
Gypsum does not form system maturation scheme using being formed, necessarily cause desulfurated plaster not to be inconsistent because of production technology, intermediate transition it is secondary
Pollution, production cost improve and influence utilization benefit.
The data gathered from China day flower prod in 2015 can see, and China's day flower prod is broadly divided into five at present
Major class：(1) Thistle board：To the north of Xinlong board, the new Mount Taishan in north, be resistant to good fortune, Lafarge, based on Saint-Gobain, the total market size is about
12.3 hundred million m2；(2) mineral wool ceiling (mineral wool sound absorption board)：To be resistant to good fortune, northern Xinlong board, based on Jinyu Star, the total market size is about
