Desulfurized lightweight plastering gypsum
Desulfurized gypsum is a byproduct of coal-fired flue gas desulfurization, which can be calcined to produce desulfurized building gypsum; Using it as the main binding material can prepare desulfurization lightweight plaster gypsum, realizing the resource utilization of desulfurization gypsum, replacing natural gypsum, and achieving the goal of protecting the ecological environment.
Desulfurized lightweight plastering gypsum is a high-performance material for building wall plastering and leveling, suitable for indoor plastering and leveling in buildings.
Property
1. Green and environmentally friendly, does not release formaldehyde or organic volatile compounds.
2. The desulfurization lightweight plastering gypsum has high bonding strength and can be used for plastering and leveling of concrete walls, red brick walls, aerated block walls, partition board walls, ceilings, etc.
3. The desulfurization lightweight plastering gypsum has a low compression ratio and good crack resistance.
4. Desulfurized lightweight plastering gypsum has slight expansion, good volume stability, and is not easily deformed or hollow.
5. Desulfurized lightweight plastering gypsum has low bulk density and is lightweight. Compared to cement mortar of the same volume, desulfurized lightweight plastering gypsum is lighter in weight, reducing transportation costs; At the same time, desulfurization lightweight plaster gypsum has a higher coating rate and a larger construction area.
6. Desulfurized lightweight plastering gypsum has good workability, easy construction, and fast speed. The materials can also be machine sprayed for construction, which shortens the construction period.
7. The desulfurization lightweight plastering gypsum has a low thermal conductivity and insulation function, providing energy-saving solutions for buildings.
8. The porous structure of desulfurization lightweight plastering gypsum can attenuate sound waves; It also helps to adsorb and release moisture, and can regulate air humidity.
9. The elastic modulus of desulfurization lightweight plastering gypsum is low, and it is not easily damaged when subjected to external impacts, with only dents appearing under strong impacts.
10. Desulfurized lightweight plastering gypsum belongs to Class A refractory materials. When exposed to fire, it will quickly release the contained crystalline water, forming steam to block the spread of flames. During the process of releasing water, gypsum absorbs a large amount of heat, which can effectively delay the rise of room temperature.
