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(diào)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(huán)境氣溫太高，濕度太低、通風(fēng)太強及陽光直曬，膩子中的復(fù)合材料反應(yīng)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(yù)防為主，注意施工環(huán)境，避免在高溫時段、陽光直曬時段施工，控制施工場地通風(fēng)強度。當(dāng)基面出現(xiàn)太過干燥、 吸水快的情況時建議刷涂界面劑或者預(yù)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(xiàn)象，嚴(yán)重的甚至出現(xiàn)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(fā)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(yán)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(jié)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(fēng)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(nèi)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(yīng)嚴(yán)格執(zhí)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(yīng)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(chǎn)生裂縫，開裂分為有規(guī)則線狀裂、“T型裂”、 網(wǎng)狀裂”、大的龜裂、不規(guī)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(dāng)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(guī)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(wǎng)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(guī)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(yán)重開裂需要鏟掉后重批；結(jié)構(gòu)松動要待結(jié)構(gòu)穩(wěn)定后施工；接縫開裂應(yīng)該預(yù)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(fēng)大，所以，夏季批膩子，主要是解決好防曬、防風(fēng)這兩個問題，當(dāng)然高溫季節(jié)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.
