抹灰砂浆适用于建筑、装修工程的内、外墙、罩面、底面、顶棚抹灰。那么济南抹灰砂浆用于建筑物内墙工程的优势是怎样的呢？下面小编为您讲讲。

The plastering mortar is applicable to the plastering of interior and exterior walls, overlays, soffits and ceilings of buildings and decoration projects. What are the advantages of Jinan plastering mortar used for building interior wall works? The following is a brief introduction.

1、调节空气湿度

1. Adjust air humidity

当外部湿度高于抹灰砂浆的相应湿度时，外部蒸汽压力高于其饱和蒸汽压力，促进内部吸水性能，从而延缓湿度的上升；当外部湿度低于抹灰石膏的相对湿度时，外部蒸汽压力低于其饱和蒸汽压力，从而促进内部水分子的蒸发。因此，它可以调节和控制湿度。

When the external humidity is higher than the corresponding humidity of the plastering mortar, the external steam pressure is higher than its saturated steam pressure, which promotes the internal water absorption performance, thus delaying the rise of humidity; When the external humidity is lower than the relative humidity of plaster gypsum, the external steam pressure is lower than its saturated steam pressure, thus promoting the evaporation of internal water molecules. Therefore, it can adjust and control humidity.

2、有效减低楼宇负荷

2. Effectively reduce building load

砂浆的单位重量为850-950kg/m3，仅传统的水泥抹灰砂浆为1800-2000kg/m3例如，如果用抹灰砂浆代替传统的水泥砂浆，则整个建筑的荷载将减少550吨。

The unit weight of mortar is 850-950kg/m3. Only the traditional cement mortar is 1800-2000kg/m3. For example, if the traditional cement mortar is replaced by the plastering mortar, the load of the whole building will be reduced by 550 tons.

3、回收利用

3. Recycling

抹灰砂浆的使用寿命与建筑物相同。废弃后可与石膏块一起破碎。低温煅烧后，具有胶凝性，可重复使用。

The service life of plastering mortar is the same as that of buildings. It can be broken together with gypsum block after being discarded. After low temperature calcination, it has gelling property and can be reused.

4、阻燃性

4. Flame retardancy

二水石膏的分子量为172，水的分子量为18。如果发生火灾，当温度达到100㎡房屋温度达到110℃以上，二水石膏会迅速释放结晶水，形成半水石膏，然后进一步转化为无水石膏，可释放560kg水。水在蒸发过程中可以吸收大量的热量，从而可以有效防止室温的快速上升，提高逃生机会。

The molecular weight of dihydrate gypsum is 172 and that of water is 18. In case of fire, when the temperature of the building reaches 100 ㎡ and the temperature reaches 110 ℃ or above, dihydrate gypsum will rapidly release crystal water to form hemihydrate gypsum, which can be further converted into anhydrite to release 560kg of water. Water can absorb a lot of heat during evaporation, which can effectively prevent the rapid rise of room temperature and improve the chance of escape.

5、施工后的墙体质量保证

5. Wall quality assurance after construction

传统水泥抹面砂浆的收缩率一般为7-9%，石膏的膨胀率为千分之一，这就决定了水泥抹面砂浆在水化过程中收缩和空鼓开裂是不可避免的，只能通过外加剂和养护来减少，但不能完全解决。砂浆具有微膨胀性，正常情况下在水化过程中不可能出现空鼓开裂，而且石膏的水化过程非常快，水化基本在24小时内完成，因此体积稳定性非常好（这就是砂浆广泛用于磨具生产的原因）。

The shrinkage rate of traditional cement plastering mortar is generally 7-9%, and the expansion rate of gypsum is one thousandth, which determines that the shrinkage and hollowing cracking of cement plastering mortar in the hydration process are inevitable, which can only be reduced through additives and curing, but can not be completely solved. Mortar has a slight expansion. Under normal circumstances, hollowing and cracking are unlikely to occur during the hydration process. Moreover, the hydration process of gypsum is very fast. The hydration is basically completed within 24 hours, so the volume stability is very good (this is why mortar is widely used in the production of abrasive tools).

其中干粉抹灰砂浆是将水泥、填料、骨料和多种功能性外加剂配制而成。不同功能的抹灰砂浆应用不同的墙体基材。比如有适用于加气混凝土砌块、粉煤灰砌块、陶粒砖等轻质墙体、有直接在混凝土剪力墙表面进行批刮的抹灰砂浆等。

The dry powder plastering mortar is composed of cement, filler, aggregate and various functional additives. Different wall substrates shall be used for plastering mortar with different functions. For example, there are light walls suitable for aerated concrete blocks, fly ash blocks, ceramsite bricks, and plastering mortars that are directly scraped on the surface of concrete shear walls.

此外抹面砂浆在施工后需要马上保养，保养需要留意施工时的溫度，在依据溫度的状况确认保养时需要准备的材料。更多相关事项就来我们网站进行咨询吧！

In addition, the plastering mortar shall be maintained immediately after construction. The maintenance shall pay attention to the temperature during construction, and the materials to be prepared for maintenance shall be confirmed according to the temperature condition.
