問題一：濟南抹面砂漿上墻干燥時間問題

Problem 1: Drying time of Jinan plastering mortar on the wall

抹灰上墻干燥時間主要與墻面吸水程度、砂漿保水性、砂漿凝結時間、環境濕度四個方面有關。

The drying time of plastering on the wall is mainly related to four aspects: water absorption of the wall, water retention of the mortar, setting time of the mortar, and environmental humidity.

1.墻面濕度正常且空氣濕度正常且施工厚度在2㎝內。此種情況上墻干燥時間正常，與現場拌制的砂漿一樣，能滿足大部份工地的使用要求。

1. The wall humidity is normal and the air humidity is normal, and the construction thickness is within 2 cm. In this case, the drying time of the wall is normal, which is the same as the mortar mixed on site and can meet the usage requirements of most construction sites.

2.墻面濕度很高或空氣濕度很高或施工厚度超過2cm。此種情況砂漿上墻干燥時間比現場拌制的砂漿要長1至3個小時。

2. The wall humidity is high or the air humidity is high, or the construction thickness exceeds 2cm. In this case, the drying time of mortar on the wall is 1 to 3 hours longer than that of on-site mixed mortar.

3.墻面濕度很高且空氣濕度很高且施工厚度超過2cm。此種情況砂漿上墻干燥時間會非常長。

3. The wall humidity is high and the air humidity is high, and the construction thickness exceeds 2cm. In this case, the drying time of mortar on the wall will be very long.

解決方法：

Solution:

1.提前1-2天對工地墻面淋水，以增加墻面對砂漿的吸水性；

1. Spray water on the construction site wall 1-2 days in advance to increase the water absorption of the wall to the mortar;

2.建議對施工很厚的部位先提前甩漿至一定厚度至標高 1~2cm 左右，待第二天一次性可補平；

2. It is recommended to spray the slurry in advance to a certain thickness of about 1-2 cm above the elevation for the thick parts during construction, and it can be leveled in one go the next day;

3.縮短砂漿的開放時間，讓砂漿快速達到凝結時間來達到縮短干燥時間的目的。

3. Shorten the opening time of the mortar, allowing it to quickly reach the setting time to achieve the goal of shortening the drying time.

問題二：砂漿粗細問題

Problem 2: The issue of mortar thickness

粗細問題是指砂漿的粗細程度，砂的粗細程度會直接影響到砂漿的粗細程度。砂漿太粗時工人施工面粗，不好抹光，砂漿太細時工人抹墻時一次抹得太薄，影響施工進度，砂漿硬化后的表面硬度也會降低。

The issue of fineness refers to the fineness of mortar, which directly affects the fineness of mortar. When the mortar is too thick, the workers' construction surface is rough and difficult to smooth. When the mortar is too fine, the workers' wall plastering is too thin at once, which affects the construction progress. The surface hardness of the hardened mortar will also decrease.

解決方法：

Solution:

生產前一定要到砂場對砂的粗細提前判斷，并將砂細度模數控制在 2.4~2.7為佳。

Before production, it is necessary to go to the sand yard to determine the thickness of the sand in advance, and it is best to control the sand fineness modulus between 2.4 and 2.7.

問題三：砂漿中的石子問題

Problem 3: Stone problem in mortar

石子問題是指砂漿中出現大的石子，嚴重影響砂漿的使用性能的情況。石子的出現主要由六個途徑帶入：（攪拌機、砂場、攪拌車、上砂地倉及皮帶、中間砂斗、篩砂機）

Stone problem refers to the occurrence of large stones in mortar, which seriously affects the performance of the mortar. The emergence of stones is mainly brought in six ways: (mixer, sand yard, mixer truck, sand bin and belt, intermediate sand hopper, and sand screening machine)

解決方法：

Solution:

1.嚴格清理機內的砂子；

1. Strictly clean the sand inside the machine;

2.強化鏟車司機的工作意識，避免鏟砂時混入石子；

2. Strengthen the work awareness of forklift drivers to avoid mixing stones when shoveling sand;

3.確保攪拌車內清洗干凈；

3. Ensure that the mixing truck is cleaned thoroughly;

4.上砂地倉及皮帶上要進行嚴格清理；

4. Strict cleaning should be carried out on the sand bin and belt;

5.要盡量避免不同材料斗相距太近，并要確保砂斗壁沒有穿孔，以確保不會混料；

5. Try to avoid different material buckets being too close together, and ensure that the sand bucket walls are not perforated to ensure no mixing of materials;

6.定期檢查篩砂機的篩網，以免破損后造成砂的質量波動。

6. Regularly check the screen of the sand screening machine to avoid damage that may cause fluctuations in the quality of the sand.
