Plaster gypsum is a kind of high-efficiency and energy-saving plastering material for building interior walls and roofs, which is made of gypsum as the main cementing material, sand, certain admixtures and special compound additives. It mainly replaces plastering materials such as cement and lime mortar, and is suitable for all kinds of walls. Compared with traditional materials, plastering gypsum has unique advantages:

　　1、粘接力强：

　　1. Strong adhesion:

　　粉刷石膏与各种墙体基材（粘土砖、水泥砌块、加气混凝土、粉煤灰砖、石膏砌块、现浇混凝土、顶棚等）都能很好地粘结，抹灰时不用刷任何界面剂，直接抹灰，一次成活，抹灰墙面不会出现空鼓、开裂现象。

　　Plaster gypsum and all kinds of wall base materials (clay brick, cement block, aerated concrete, fly ash brick, gypsum block, cast-in-situ concrete, roof, etc.) can be well bonded, plastering without any interface agent, plastering directly, once survived, plastering wall surface will not appear empty drum, cracking phenomenon.

　　2、表面装饰性：

　　2. Surface decoration:

　　粉刷石膏墙面细腻光滑而不起灰，强度高、不收缩，外观典雅，无气味，不返碱，无裂纹。

　　Painting gypsum wall surface is fine and smooth without ash, high strength, no shrinkage, elegant appearance, no odor, no alkali, no cracks.

　　3、防火性能：

　　3. Fire protection performance:

　　当粉刷石膏抹面厚度为20mm时，耐火极限可达到2小时以上。

　　When the thickness of plastering plaster is 20 mm, the fire resistance limit can reach more than 2 hours.

　　4、呼吸功能：

　　4. Respiratory function:

　　粉刷石膏硬化过程中，形成无数个微小的蜂窝状呼吸孔，当室内环境湿度较大时，呼吸孔自动吸湿；在相反条件下，能自动释放储备水分。

　　In the process of plastering gypsum hardening, innumerable tiny honeycomb breathing holes are formed. When the indoor environment humidity is high, the breathing holes absorb moisture automatically. Under the opposite conditions, the reserve moisture can be released automatically.

　　5、保温隔热：

　　5. Insulation and insulation:

　　石膏制品导热系数小，约为水泥砼制品导热系数25%，粘土砖的30%。

　　The thermal conductivity of gypsum products is small, which is about 25% of that of cement concrete products and 30% of that of clay bricks.

　　6、节省工期、节约成本：

　　6. Saving time and cost:

　　粉刷石膏抹灰层凝结硬化快，养护周期短，整个硬化及强度达标过程5-7天全部完成，可大大提高工作效率，加快后续工程进度，与水泥混合砂浆相比可以提前工期1-2月的时间。

　　The plastering gypsum plaster layer has the advantages of fast setting and hardening, short curing period, complete hardening and strength up to standard in 5-7 days, which can greatly improve work efficiency and speed up the progress of follow-up projects. Compared with cement mortar, the plastering gypsum plastering layer can advance the construction period by 1-2 months.

　　7、施工方便：

　　7. Convenient construction:

　　抹灰施工中具有易抹、易刮平、易修补，劳动强度低，材料消耗少，冬季施工不受气温降低至接近0℃时影响等特点。

　　The plastering construction has the characteristics of easy plastering, easy scraping, easy repairing, low labor intensity, less material consumption, and winter construction is not affected by the temperature drop to nearly 0 C.

　　8、隔音性能：

　　8. Sound insulation performance:

　　粉刷石膏在凝结过程中，内部产生微小的孔隙，因此能衰减声压，又可防止声能透射，具有良好的隔音性能。

　　During the condensation process of plastering gypsum, there are tiny holes in the interior, so it can attenuate the sound pressure and prevent the transmission of sound energy, so it has good sound insulation performance.

　　9、卫生健康性：

　　9. Health:

　　石膏具有消毒杀毒作用，在石膏材料装修房间里，细菌难以生存和传播。用粉刷石膏的房间尤其适用于婴幼儿和老年人居住。

　　Gypsum has the function of disinfection and disinfection. It is difficult for bacteria to survive and spread in gypsum material decorated rooms. The rooms painted with gypsum are especially suitable for infants and the elderly.
