進(jìn)入冬季，濟(jì)南氣溫持續(xù)走低，不少裝修施工隊(duì)和業(yè)主在進(jìn)行抹灰施工時(shí)都會(huì)犯嘀咕：天冷了水分蒸發(fā)慢，抹面砂漿還需要澆水養(yǎng)護(hù)嗎？甚至有不少人覺得“低溫能減緩干燥，不養(yǎng)護(hù)也沒事”。其實(shí)這種想法存在明顯誤區(qū)，結(jié)合濟(jì)南本地氣候特點(diǎn)和砂漿施工原理來看，即便天寒，抹面砂漿的澆水養(yǎng)護(hù)也必不可少。今天就專門針對(duì)這個(gè)問題，給大家做一次詳細(xì)科普。

　　Entering winter, the temperature in Jinan continues to drop, and many decoration construction teams and homeowners will have doubts when carrying out plastering construction: does the water evaporate slowly when it gets cold, and does the plastering mortar still need to be watered for maintenance? Many people even think that 'low temperature can slow down drying, and it's okay without maintenance'. In fact, this idea has obvious misconceptions. Based on the local climate characteristics of Jinan and the principles of mortar construction, even in cold weather, watering and curing the plastering mortar is essential. Today, we will provide a detailed science popularization specifically for this issue.

　　要搞懂為什么天冷也要養(yǎng)護(hù)，首先得明白養(yǎng)護(hù)的核心作用。很多人誤以為養(yǎng)護(hù)只是為了防止砂漿干燥太快，其實(shí)不然，它更是保障墻面質(zhì)量的關(guān)鍵環(huán)節(jié)。具體來說，主要有三個(gè)核心原因，這每一點(diǎn)都和濟(jì)南的施工場(chǎng)景息息相關(guān)。

　　To understand why maintenance is necessary even in cold weather, one must first understand the core role of maintenance. Many people mistakenly believe that maintenance is just to prevent mortar from drying out too quickly, but in fact, it is a key link in ensuring the quality of the wall. Specifically, there are three core reasons, each of which is closely related to the construction scene in Jinan.

　　第一，保障砂漿強(qiáng)度達(dá)標(biāo)。砂漿強(qiáng)度的形成，依賴于其中水泥的水化反應(yīng)，而這個(gè)反應(yīng)需要充足的水分和適宜的環(huán)境。濟(jì)南冬季雖然干燥速度比夏季慢，但低溫本身會(huì)減緩水化反應(yīng)的進(jìn)程。如果不進(jìn)行澆水養(yǎng)護(hù)，砂漿中的水分會(huì)慢慢蒸發(fā)，水化反應(yīng)還沒完全進(jìn)行就會(huì)被迫停止，最終形成的墻面強(qiáng)度會(huì)大打折扣，后期容易出現(xiàn)起砂、脫落等問題。尤其濟(jì)南冬季多風(fēng)，即便氣溫低，風(fēng)力也會(huì)加速表面水分流失，進(jìn)一步影響反應(yīng)效果，所以澆水養(yǎng)護(hù)能為水化反應(yīng)提供持續(xù)的水分支持，讓砂漿強(qiáng)度穩(wěn)步提升。

　　Firstly, ensure that the mortar strength meets the standard. The formation of mortar strength depends on the hydration reaction of cement, which requires sufficient moisture and suitable environment. Although the drying speed in winter in Jinan is slower than in summer, the low temperature itself will slow down the process of hydration reaction. If watering and maintenance are not carried out, the water in the mortar will slowly evaporate, and the hydration reaction will be forced to stop before it is fully carried out. The strength of the resulting wall will be greatly reduced, and problems such as sanding and peeling may occur in the later stage. Especially in winter in Jinan, it is windy, and even if the temperature is low, the wind will accelerate the loss of surface moisture, further affecting the reaction effect. Therefore, watering and curing can provide continuous moisture support for the hydration reaction and steadily improve the strength of the mortar.

　　第二，避免墻體反堿影響美觀。抹面砂漿中含有一定的堿性物質(zhì)，這是材料本身的特性。如果不進(jìn)行澆水養(yǎng)護(hù)，這些堿性物質(zhì)會(huì)隨著水分的蒸發(fā)慢慢滲透到墻面表層，形成一層白色的堿霜，也就是大家常說的“反堿”。濟(jì)南冬季室內(nèi)外溫差大，墻體容易出現(xiàn)冷凝水，會(huì)加劇反堿現(xiàn)象，不僅影響墻面美觀，還可能影響后續(xù)涂料、壁紙的施工效果。而澆水養(yǎng)護(hù)能通過水分沖刷，帶走部分表層的堿性物質(zhì)，從源頭減少反堿問題的發(fā)生。

　　Secondly, avoid the anti alkali effect on the appearance of the wall. The plastering mortar contains a certain amount of alkaline substances, which is a characteristic of the material itself. If not watered and maintained, these alkaline substances will slowly penetrate into the surface of the wall as water evaporates, forming a white alkali frost, commonly known as "anti alkali". In winter in Jinan, there is a large temperature difference between indoor and outdoor areas, which makes it easy for condensation water to occur on the walls, exacerbating the anti alkali phenomenon. This not only affects the appearance of the walls, but may also affect the construction effect of subsequent coatings and wallpapers. Watering and maintenance can remove some alkaline substances from the surface layer through water flushing, reducing the occurrence of anti alkali problems from the source.

　　第三，保證墻面平整度，助力后續(xù)施工。砂漿涂抹打磨后，表面難免會(huì)殘留一些纖維絲和灰塵，這些雜質(zhì)會(huì)讓墻面變得粗糙。如果不清理干凈，后續(xù)噴底漆時(shí)，底漆很難均勻滲透，容易出現(xiàn)起皮、脫落的情況。天冷時(shí)施工，砂漿干燥速度慢，恰好給了澆水清理的充足時(shí)間。通過澆水沖洗，既能徹底清除表面雜質(zhì)，讓墻面更光滑，還能讓墻面保持適度濕潤(rùn)，為后續(xù)工序打下良好基礎(chǔ)。

　　Thirdly, ensure the flatness of the wall surface to assist in subsequent construction. After applying and polishing the mortar, it is inevitable that some fibers and dust will remain on the surface, which will make the wall rough. If not cleaned thoroughly, it will be difficult for the primer to penetrate evenly during subsequent spraying, which may lead to peeling and detachment. Construction is carried out in cold weather, and the drying speed of mortar is slow, which provides ample time for watering and cleaning. By watering and rinsing, surface impurities can be thoroughly removed to make the wall smoother, and the wall can be kept moderately moist, laying a good foundation for subsequent processes.

　　這里還要提醒大家，濟(jì)南冬季澆水養(yǎng)護(hù)也有講究，盡量選擇中午氣溫較高的時(shí)段進(jìn)行，避免水分在墻面結(jié)冰，反而損傷砂漿層。養(yǎng)護(hù)頻率無需過高，保持墻面濕潤(rùn)即可，一般持續(xù)3-5天。

　　Here we would like to remind everyone that there are also precautions for watering and maintenance in Jinan during winter. It is recommended to choose the time when the temperature is higher at noon to avoid water freezing on the wall and damaging the mortar layer. The maintenance frequency does not need to be too high, just keep the wall moist, usually lasting for 3-5 days.

　　總之，無論氣溫高低，抹面砂漿澆水養(yǎng)護(hù)都是不可或缺的環(huán)節(jié)。尤其是在濟(jì)南冬季特殊的氣候條件下，做好養(yǎng)護(hù)工作，才能保證墻面的強(qiáng)度、美觀度和耐久性。希望這次科普能幫大家糾正認(rèn)知誤區(qū)，讓裝修施工少走彎路。

　　In short, regardless of the temperature, watering and curing the plastering mortar is an indispensable step. Especially under the special winter climate conditions in Jinan, proper maintenance work is necessary to ensure the strength, aesthetics, and durability of the walls. I hope this science popularization can help everyone correct their cognitive misconceptions and avoid detours in decoration construction.
