問(wèn)題一：濟(jì)南抹面砂漿上墻干燥時(shí)間問(wèn)題

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

抹灰上墻干燥時(shí)間主要與墻面吸水程度、砂漿保水性、砂漿凝結(jié)時(shí)間、環(huán)境濕度四個(gè)方面有關(guān)。

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(nèi)。此種情況上墻干燥時(shí)間正常，與現(xiàn)場(chǎng)拌制的砂漿一樣，能滿(mǎn)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(guò)2cm。此種情況砂漿上墻干燥時(shí)間比現(xiàn)場(chǎng)拌制的砂漿要長(zhǎng)1至3個(gè)小時(shí)。

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(guò)2cm。此種情況砂漿上墻干燥時(shí)間會(huì)非常長(zhǎng)。

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(duì)工地墻面淋水，以增加墻面對(duì)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(duì)施工很厚的部位先提前甩漿至一定厚度至標(biāo)高 1~2cm 左右，待第二天一次性可補(bǔ)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(kāi)放時(shí)間，讓砂漿快速達(dá)到凝結(jié)時(shí)間來(lái)達(dá)到縮短干燥時(shí)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(wèn)題二：砂漿粗細(xì)問(wèn)題

Problem 2: The issue of mortar thickness

粗細(xì)問(wèn)題是指砂漿的粗細(xì)程度，砂的粗細(xì)程度會(huì)直接影響到砂漿的粗細(xì)程度。砂漿太粗時(shí)工人施工面粗，不好抹光，砂漿太細(xì)時(shí)工人抹墻時(shí)一次抹得太薄，影響施工進(jìn)度，砂漿硬化后的表面硬度也會(huì)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(chǎn)前一定要到砂場(chǎng)對(duì)砂的粗細(xì)提前判斷，并將砂細(xì)度模數(shù)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(wèn)題三：砂漿中的石子問(wèn)題

Problem 3: Stone problem in mortar

石子問(wèn)題是指砂漿中出現(xiàn)大的石子，嚴(yán)重影響砂漿的使用性能的情況。石子的出現(xiàn)主要由六個(gè)途徑帶入：（攪拌機(jī)、砂場(chǎng)、攪拌車(chē)、上砂地倉(cāng)及皮帶、中間砂斗、篩砂機(jī)）

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(yán)格清理機(jī)內(nèi)的砂子；

1. Strictly clean the sand inside the machine;

2.強(qiáng)化鏟車(chē)司機(jī)的工作意識(shí)，避免鏟砂時(shí)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(chē)內(nèi)清洗干凈；

3. Ensure that the mixing truck is cleaned thoroughly;

4.上砂地倉(cāng)及皮帶上要進(jìn)行嚴(yán)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(méi)有穿孔，以確保不會(huì)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(jī)的篩網(wǎng)，以免破損后造成砂的質(zhì)量波動(dòng)。

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