Foaming modified desulfurized gypsum wallboard
The invention relates to a foaming modified desulfurized gypsum wallboard, and discloses a gypsum wallboard and a preparation method thereof which needs no calcination treatment on desulfurized gypsumand reduces the preparation cost. The gypsum wallboard is characterized by comprising an inner wall body made of a desulfurized gypsum composite material and an anti-bending base material arranged inthe inner wall body. The dry density of the material is reduced through a foaming technology, the activity of the desulfurized gypsum composite material is excited by cooperating with a saline-alkalidual activator, calcination treatment on desulfurized gypsum is not needed, the activity of admixtures such as desulfurized gypsum and slag powder is excited through an alkali activator, gypsum calcination is not needed, and the material strength can be obtained through low-temperature and normal-pressure maintenance.
本发明发泡改性脱硫石膏墙板公开了一种无需对脱硫石膏进行煅烧处理，制备成本降低的石膏墙板及其制备方法，其特征在于包括脱硫石膏复合材料制成的内墙体，以及设置在内墙体内的抗弯基材，通过发泡技术降低材料干密度,配合盐碱双激发剂激发脱硫石膏复合材料活性，无需对脱硫石膏进行煅烧处理，通过碱激发剂，激发了脱硫石膏以及矿渣粉等掺和物活性，不需要煅烧石膏，低温常压养护即可获得材料强度。
