以脱硫建筑石膏、粉煤灰、发泡剂为原材料制备发泡脱硫石膏保温材料。研究不同发泡剂掺量对其密度、力学性能和导热系数的影响，结果表明，发泡剂掺量为5%时，导热系数最小，为0.052 W/(m·K)，此时脱硫石膏发泡材料的密度为225 kg/m3。利用玻璃纤维作为增强材料，研究了玻璃纤维的掺加对材料强度的影响。结果表明，当玻璃纤维掺量为1.5%时，试样的抗折强度提高了41.67%。
以脫硫建築石膏、粉煤灰、髮泡劑為原材料製備髮泡脫硫石膏保溫材料。研究不同髮泡劑摻量對其密度、力學性能和導熱繫數的影響，結果錶明，髮泡劑摻量為5%時，導熱繫數最小，為0.052 W/(m·K)，此時脫硫石膏髮泡材料的密度為225 kg/m3。利用玻璃纖維作為增彊材料，研究瞭玻璃纖維的摻加對材料彊度的影響。結果錶明，噹玻璃纖維摻量為1.5%時，試樣的抗摺彊度提高瞭41.67%。

The paper researches a kind of insulation foamed desulfurization gypsum material prepared by the desulfurization gypsum, foaming agent and fly ash from the aspects of the influence of different content of foaming agent on its density, mechanical properties and thermal conductivity. The result shows that when the content of foaming agent is 5%, the thermal conductivity is minimum heat conduction coefficient of 0.052 W/(m·K), and the density of foamed desulfurization gypsum is 225 kg/m3 . And also researches the effect of additive content of glass fiber as reinforcing material on strength of the material. The result shows that when the content of glass fiber is 1.5%, the transverse strength of the sample increases 41.67%.
