抹灰砂漿用于建筑物內墻工程的優勢

來源：http://www.wavc.cn 日期：2022-10-13 發布人：

抹灰砂漿適用于建筑、裝修工程的內、外墻、罩面、底面、頂棚抹灰。那么濟南抹灰砂漿用于建筑物內墻工程的優勢是怎樣的呢？下面小編為您講講。

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、調節空氣濕度

1. Adjust air humidity

當外部濕度高于抹灰砂漿的相應濕度時，外部蒸汽壓力高于其飽和蒸汽壓力，促進內部吸水性能，從而延緩濕度的上升；當外部濕度低于抹灰石膏的相對濕度時，外部蒸汽壓力低于其飽和蒸汽壓力，從而促進內部水分子的蒸發。因此，它可以調節和控制濕度。

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、有效減低樓宇負荷

2. Effectively reduce building load

砂漿的單位重量為850-950kg/m3，僅傳統的水泥抹灰砂漿為1800-2000kg/m3例如，如果用抹灰砂漿代替傳統的水泥砂漿，則整個建筑的荷載將減少550噸。

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

抹灰砂漿的使用壽命與建筑物相同。廢棄后可與石膏塊一起破碎。低溫煅燒后，具有膠凝性，可重復使用。

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

二水石膏的分子量為172，水的分子量為18。如果發生火災，當溫度達到100㎡房屋溫度達到110℃以上，二水石膏會迅速釋放結晶水，形成半水石膏，然后進一步轉化為無水石膏，可釋放560kg水。水在蒸發過程中可以吸收大量的熱量，從而可以有效防止室溫的快速上升，提高逃生機會。

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、施工后的墻體質量保證

5. Wall quality assurance after construction

傳統水泥抹面砂漿的收縮率一般為7-9%，石膏的膨脹率為千分之一，這就決定了水泥抹面砂漿在水化過程中收縮和空鼓開裂是不可避免的，只能通過外加劑和養護來減少，但不能完全解決。砂漿具有微膨脹性，正常情況下在水化過程中不可能出現空鼓開裂，而且石膏的水化過程非常快，水化基本在24小時內完成，因此體積穩定性非常好（這就是砂漿廣泛用于磨具生產的原因）。

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).

其中干粉抹灰砂漿是將水泥、填料、骨料和多種功能性外加劑配制而成。不同功能的抹灰砂漿應用不同的墻體基材。比如有適用于加氣混凝土砌塊、粉煤灰砌塊、陶粒磚等輕質墻體、有直接在混凝土剪力墻表面進行批刮的抹灰砂漿等。

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.

此外抹面砂漿在施工后需要馬上保養，保養需要留意施工時的溫度，在依據溫度的狀況確認保養時需要準備的材料。更多相關事項就來我們網站http://www.wavc.cn進行咨詢吧！

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.
