1. Strong adhesion: plastering plaster and various wall substrates (clay brick, cement block, aerated concrete, fly ash brick, gypsum block, cast-in-place concrete, ceiling, etc.) can be well Bonding, no need to brush any interface agent when plastering, plastering directly, one-time survival, the plastering wall will not appear hollow and cracking.
2. Surface decoration: plastering plaster walls are fine and smooth without ash, high strength, no shrinkage, elegant appearance, no odor, no alkali return, no cracks.
3. Fire resistance: when the thickness of the plastering plaster is 20mm, the fire resistance limit can reach more than 2 hours.
4. Thermal insulation: The thermal conductivity of gypsum products is small, about 25% of that of cement concrete products and 30% of that of clay bricks.
5. Save construction period and cost: the plastering plaster layer hardens quickly, the maintenance period is short, and the entire hardening and strength compliance process is completed in 5-7 days, which can greatly improve work efficiency, speed up the progress of subsequent projects, and mix mortar with cement Compared with the time that can be advanced by 1-2 months.
6. Convenient construction: The plastering construction has the characteristics of easy wiping, easy scraping, easy repair, low labor intensity, low material consumption, and winter construction is not affected when the temperature drops to close to 0 °C.
7. Sound insulation performance: During the setting process of plastering gypsum, tiny pores are generated inside, so it can attenuate sound pressure and prevent sound energy transmission, and has good sound insulation performance.
8. Breathing function: During the hardening process of plastering gypsum, countless tiny honeycomb breathing holes are formed. When the indoor environment humidity is high, the breathing holes automatically absorb moisture; under the opposite conditions, they can automatically release the stored moisture.
9. Hygiene and health: Gypsum has the function of disinfecting and disinfecting. In the room decorated with gypsum materials, it is difficult for bacteria to survive and spread. Rooms painted with plaster are especially suitable for infants and the elderly.
10. Green environmental protection: Gypsum is known as the green environmental protection building material in the 21st century. It can be eaten and has been widely used as traditional Chinese medicine since ancient times. Therefore, it has become a good choice as a building material for decoration.
