在濟南的建筑施工戰場上，抹面砂漿就像構筑墻面的 “美容師”，能讓粗糙的基層變得平整光滑。然而，這一得力 “助手” 若保存不當，就會像變質的食材，失去原本的性能。濟南四季分明，夏季高溫多雨，冬季寒冷干燥，面對這樣多變的氣候，掌握抹面砂漿的 “保鮮秘籍” 至關重要，只有科學儲存，才能讓它時刻保持良好狀態，在施工時發揮最佳效果。

　　On the battlefield of construction in Jinan, plastering mortar is like a "beautician" for building walls, which can make rough substrates smooth and even. However, if this capable "assistant" is not stored properly, it will be like spoiled food and lose its original performance. Jinan has distinct four seasons, with hot and rainy summers and cold and dry winters. Faced with such a changing climate, it is crucial to master the "preservation secrets" of plastering mortar. Only through scientific storage can it be kept in good condition at all times and achieve the best results during construction.

　　儲存環境的選擇是保存抹面砂漿的首要關鍵。首先，存放地點必須保證干燥，避免潮濕空氣侵襲。濟南夏季降水較多，空氣濕度大，若將抹面砂漿置于潮濕環境中，其中的水泥等膠凝材料會吸收水分，提前發生水化反應，導致砂漿結塊硬化，無法正常使用。因此，倉庫地面應進行防潮處理，可鋪設防潮墊板或塑料薄膜，使砂漿與地面隔開；墻面也可涂刷防潮涂料，進一步隔絕濕氣。同時，倉庫要具備良好的通風條件，保持空氣流通，防止濕氣積聚。在冬季，濟南氣溫較低，尤其是夜間，低溫可能會使砂漿中的水分結冰，破壞其內部結構，影響強度。所以，倉庫需做好保溫措施，可在倉庫外圍覆蓋保溫材料，如巖棉板等，必要時還可在倉庫內安裝供暖設備，將溫度維持在適宜范圍，避免砂漿受凍。

　　The selection of storage environment is the primary key to preserving plaster mortar. Firstly, the storage location must be kept dry to avoid the invasion of humid air. Jinan has more precipitation in summer and high air humidity. If the plastering mortar is placed in a humid environment, the cement and other cementitious materials will absorb moisture and undergo hydration reactions in advance, causing the mortar to clump and harden, making it unable to be used normally. Therefore, the warehouse floor should be treated with moisture-proof measures, such as laying moisture-proof pads or plastic films to separate the mortar from the floor; The wall can also be coated with moisture-proof paint to further isolate moisture. At the same time, the warehouse should have good ventilation conditions, maintain air circulation, and prevent moisture accumulation. In winter, the temperature in Jinan is relatively low, especially at night. The low temperature may cause the moisture in the mortar to freeze, damaging its internal structure and affecting its strength. Therefore, the warehouse needs to take good insulation measures. Insulation materials such as rock wool boards can be covered around the warehouse, and if necessary, heating equipment can be installed inside the warehouse to maintain the temperature within a suitable range and avoid the mortar from freezing.

　　包裝完整性對抹面砂漿的保存也有著重要影響。未開封的抹面砂漿應存放在原包裝內，包裝袋要保持密封狀態。優質的包裝材料能夠有效阻擋外界水分和空氣進入，延長砂漿的保質期。在搬運過程中，要輕拿輕放，避免包裝袋破損，一旦發現包裝有裂縫、孔洞，應立即進行修補或更換包裝，防止砂漿受潮。對于開封后未使用完的砂漿，更要妥善處理。可使用密封夾將袋口夾緊，或轉移至密封容器中，盡量排出容器內的空氣，減少與空氣的接觸面積，降低受潮風險。

　　The integrity of packaging also has a significant impact on the preservation of plastering mortar. Unopened plastering mortar should be stored in its original packaging, and the packaging bag should be kept sealed. High quality packaging materials can effectively block external moisture and air from entering, extending the shelf life of mortar. During the transportation process, handle with care to avoid damage to the packaging bag. Once cracks or holes are found in the packaging, they should be repaired or replaced immediately to prevent the mortar from getting damp. For unused mortar after opening, it is even more important to handle it properly. You can use a sealing clip to clamp the bag opening or transfer it to a sealed container to exhaust the air inside the container as much as possible, reduce the contact area with air, and lower the risk of moisture.

　　在保存過程中，還要遵循先進先出的原則。先購入的抹面砂漿應優先使用，避免因存放時間過長而降低性能。即使在良好的儲存條件下，抹面砂漿也有一定的保質期，一般干混抹面砂漿保質期在 3 - 6 個月左右，具體需參照產品說明。定期對庫存的抹面砂漿進行檢查，查看是否有結塊、硬化、變色等異常現象。若發現少量結塊，可通過篩選去除結塊部分，剩余未結塊的砂漿經檢測合格后仍可使用；但如果結塊嚴重，或出現明顯異味、變色等情況，說明砂漿已變質，不可再用于施工，以免影響工程質量。

　　During the storage process, the principle of first in, first out should also be followed. The plaster mortar purchased first should be used first to avoid a decrease in performance due to prolonged storage time. Even under good storage conditions, plastering mortar has a certain shelf life. Generally, dry mixed plastering mortar has a shelf life of about 3-6 months, which should be referred to in the product instructions. Regularly inspect the inventory of plastering mortar to see if there are any abnormal phenomena such as clumping, hardening, discoloration, etc. If a small amount of clumps are found, the clumped parts can be removed by screening, and the remaining un clumped mortar can still be used after passing the inspection; But if the clumping is severe, or there is a noticeable odor, discoloration, etc., it indicates that the mortar has deteriorated and cannot be used for construction again to avoid affecting the quality of the project.

　　此外，不同類型的抹面砂漿保存要求也略有差異。例如，具有特殊功能的防水抹面砂漿、保溫抹面砂漿等，除了遵循上述通用保存方法外，還需根據其特性進行針對性儲存。防水抹面砂漿對防潮要求更高，應盡量存放在濕度更低的環境中；保溫抹面砂漿則要避免重壓和尖銳物碰撞，防止破壞其內部的保溫結構。

　　In addition, the storage requirements for different types of plastering mortar also vary slightly. For example, waterproof plastering mortar, insulation plastering mortar, etc. with special functions need to be stored according to their characteristics in addition to following the general preservation methods mentioned above. Waterproof plastering mortar requires higher moisture resistance and should be stored in an environment with lower humidity as much as possible; The insulation plaster mortar should avoid heavy pressure and sharp object collision to prevent damage to its internal insulation structure.

　　濟南抹面砂漿的科學保存，是一場與環境、時間的 “博弈”。從儲存環境的精心打造，到包裝的妥善維護，再到使用過程中的合理管理，每一個環節都不容忽視。掌握這些 “保鮮秘籍”，就能讓抹面砂漿長久 “在線”，為濟南的建筑工程添磚加瓦，筑起堅固又美觀的墻面。

　　The scientific preservation of Jinan plaster mortar is a game between environment and time. From the careful creation of storage environment, to the proper maintenance of packaging, to the reasonable management during use, every link cannot be ignored. Mastering these "preservation secrets" can make the plastering mortar "online" for a long time, adding bricks and tiles to the construction projects in Jinan, and building strong and beautiful walls.
