干混抹灰砂漿用優質水泥為主要粘結基料，精確篩分并制得的河沙，配以高品質的保水增稠材料，用精確計量的干混劑，用雙軸強制攪拌器攪拌而成，是采用優質聚合物設計制造的專用改良干粉，只需現場加水后按要求用機械攪拌即可使用。保水率是一項很重要的指標，那保水率對干混抹灰砂漿有什么影響呢？下面濟南抹面砂漿廠家為你分析：

The dry mixed plastering mortar is mainly composed of high-quality cement as the main bonding material, accurately screened and prepared river sand, combined with high-quality water retaining and thickening materials, accurately measured dry mixing agent, and mixed with a dual axis forced mixer. It is a specialized improved dry powder designed and manufactured with high-quality polymer, and can be used only by adding water on site and mechanically stirring according to requirements. Water retention rate is a very important indicator, so what is the impact of water retention rate on dry mixed plastering mortar? Below, Jinan plastering mortar manufacturer will analyze for you:

一、保水性差會導致塑性開裂；砂漿保水性差，水分容易流失，尤其是對于吸水快的加氣塊墻，水分被基材吸走，而干混抹灰砂漿沒有凝結，無法抵抗體積收縮引起的拉應力，導致出現不規則裂紋。

1、 Poor water retention can lead to plastic cracking; Mortar has poor water retention and is prone to water loss, especially for aerated block walls that absorb water quickly. Water is absorbed by the substrate, while dry mixed plastering mortar does not set and cannot resist tensile stress caused by volume shrinkage, resulting in irregular cracks.

二、保水率差，會造成空鼓；干混抹灰砂漿泌水會造成砂漿成分不均勻，導致整體性能下降。對于干混抹灰砂漿，水分流失快，容易被基材奪走，水泥水化不充分，降低了砂漿與基材的粘結力。隨著溫度和濕度的變化，砂漿會發生體積變形，形成應力，導致砂漿與基材分離。這種現象是砂漿空鼓的主要原因。

2、 Poor water retention rate can cause hollowing; The bleeding of dry mixed plastering mortar can cause uneven mortar composition, leading to a decrease in overall performance. For dry mixed plastering mortar, water loss is fast, it is easy to be taken away by the substrate, and the cement hydration is insufficient, reducing the bonding force between the mortar and the substrate. With changes in temperature and humidity, the mortar will undergo volume deformation, forming stress, leading to separation between the mortar and the substrate. This phenomenon is the main cause of mortar hollowing.

三、保水性差，施工性差；干混抹灰砂漿的保水性差，會產生砂漿泌水，砂漿在加水攪拌后的運輸過程中或放置過程中，會產生分層與上、中、底層稠度不同，造成粘結性差，抹灰易落灰，砂漿操作性差等后果。

3、 Poor water retention and construction performance; The poor water retention of dry mixed plastering mortar can result in mortar bleeding. During the transportation or placement process after mixing with water, the mortar will have different layers and the consistency of the upper, middle, and bottom layers, resulting in poor adhesion, easy falling of the plaster, and poor operability of the mortar.
