夏天的時候刮膩子都會出現哪些問題？

來源：http://www.wavc.cn 日期：2021-01-28 發布人：

夏天的時候天氣總體來說比較的炎熱，溫度相對來說也比較高。但是有些人也會選擇在夏天的時候進行房屋的裝修。在夏天的時候進行房屋裝修，不但對裝修工人的體力來說是一個巨大的挑戰，甚至對裝修材料來說，能不能良好的進行使用，也是一個很大的問題，尤其是刮膩子。那么夏天進行裝修，膩子粉容易出現哪些問題呢？濟南膩子粉廠家的小編匯總了三個主要的問題。

In summer, the weather is generally hot and the temperature is relatively high. But some people also choose to decorate their houses in the summer. House decoration in summer is not only a great challenge to the physical strength of decoration workers, but also a big problem to the decoration materials, especially putty. So summer decoration, putty powder prone to what problems? Jinan putty powder manufacturers summarized three main problems.

問題一：干得快

Problem 1: fast work

膩子粉料在桶里調配時干的很快，難施工，批刮后失水快，不能正常收壓或施工后干燥過快。

The putty powder dries very fast when it is mixed in the bucket, so it is difficult to construct. It loses water quickly after scraping. It can't be compressed normally or dried too fast after construction.

原因：施工環境氣溫太高，濕度太低、通風太強及陽光直曬，膩子中的復合材料反應加速。

Reasons: the temperature of construction environment is too high, the humidity is too low, the ventilation is too strong and the sunlight is direct, and the reaction of composite materials in putty is accelerated.

解決方案：預防為主，注意施工環境，避免在高溫時段、陽光直曬時段施工，控制施工場地通風強度。當基面出現太過干燥、吸水快的情況時建議刷涂界面劑或者預先濕潤基面(但不能有明水)再施工。

Solution: prevention first, pay attention to the construction environment, avoid construction in high temperature period and direct sunlight period, and control the ventilation intensity of the construction site. When the base surface is too dry and absorbs water quickly, it is recommended to brush the interface agent or wet the base surface in advance (but there is no open water) before construction.

問題二：掉粉、脫層

Problem 2: powder falling and delamination

施工完成及干透后，用手觸摸有掉粉現象，嚴重的甚至出現前后兩道膩子之間或膩子與基底之間相互剝離。

After the construction is completed and dried thoroughly, there is powder dropping phenomenon when touching with hands. In serious cases, there is even peeling between the front and back putty or between the putty and the base.

原因：膩子在高溫干燥時施工，水分揮發快，沒有足夠水分進行固化，因而容易脫粉。而底層膩子疏松粉化嚴重，面層膩子太硬，干燥太快會造成脫層。另外,外墻膩子被雨水沖刷后，粘結劑流失，重批后也容易脫層。

Reason: Putty in high temperature dry construction, moisture volatilization fast, not enough moisture for curing, so easy to powder. The bottom layer putty is loose and powdered seriously, the surface layer putty is too hard, drying too fast will cause delamination. In addition, after the external wall putty is washed by rain, the binder is lost, and it is easy to peel off after re approval.

解決方案：高溫、干燥強風天氣施工，更好將基面潤濕無明水后再進行膩子施工。施工時要收壓密實，適度掌握干燥時間。處理起來具體情況具體分析:

Solution: high temperature, dry and windy weather construction, it is best to wet the base surface without water before putty construction. During the construction, the pressure should be collected and compacted, and the drying time should be controlled appropriately. The specific situation is analyzed in detail

1、內墻耐水膩子涂過封閉底漆后，強度會增加，一般無需另行處理。

1. The strength of water-resistant putty for interior wall will increase after being coated with sealing primer, so it does not need to be treated separately.

2、外墻膩子應嚴格執行保濕施工，避免陽光直射施工，面層膩子表干后及時適度打磨并充分淋水2次以上。

2. The external wall putty shall strictly implement the moisturizing construction to avoid direct sunlight construction. After the surface layer putty is dry, it shall be timely and moderately polished and fully watered for more than 2 times.

3、壓光膩子表面應再薄批膩子一道，并及時進行壓光處理。

3. The surface of calendered putty shall be applied with a thin layer of putty and calendered in time.

問題三：開裂

Problem 3: cracking

膩子層產生裂縫，開裂分為有規則線狀裂、“T型裂”、網狀裂”、大的龜裂、不規則短線狀裂、局部小龜裂、陰角同時有較多垂直短線裂等。

The cracks in the putty layer can be divided into regular linear cracks, "T-shaped cracks", reticular cracks, large cracks, irregular short linear cracks, local small cracks, and many vertical short linear cracks in the internal corner.

原因：單遍批刮太厚，干燥太快，表干里不干，當然裂紋有多種，主要有以下幾種。

Reason: single pass batch scraping is too thick, drying is too fast, surface drying is not dry, of course, there are many kinds of cracks, mainly the following.

1、有規則線狀裂主要是裂縫處開裂。

1. The regular linear crack is mainly at the crack.

2、“T型裂”、“網狀裂”主要是基層開裂。

2. The "T-type crack" and "network crack" are mainly the base crack.

3、大的龜裂及不規則較短線狀裂紋是膩子批刮太厚的干裂。

3. Large cracks and irregular short linear cracks are dry cracks of too thick putty.

4、陰角裂同時有較多垂直短線裂主要是基層太松或修角膩子太硬、太厚。

4. At the same time, there are many vertical short line cracks in internal corner cracks, mainly because the base is too loose or the corner putty is too hard or too thick.

解決方案：膩子嚴重開裂需要鏟掉后重批；結構松動要待結構穩定后施工；接縫開裂應該預先做好接縫處理再批刮膩子。

Solutions: serious cracks of putty need to be removed and re approved; structural looseness needs to be constructed after the structure is stable; joint cracking should be treated in advance before putty is applied.

因為夏季溫度高風大，所以，夏季批膩子，主要是解決好防曬、防風這兩個問題，當然高溫季節施工，工人防中暑的工作也要做好。

Because of the high temperature and strong wind in summer, the main purpose of applying putty in summer is to solve the two problems of sun protection and wind protection. Of course, workers should also do a good job in heatstroke prevention during construction in high temperature season.
