作為墻面施工必不可少的一道工序，如果膩子層的施工效果出現(xiàn)問題，外飾面層整體效果將大打折扣。在如此環(huán)境下施工，可能會面臨的問題是什么？為了不讓環(huán)境影響濟南膩子粉的施工性，我們應(yīng)該怎么做呢？

As an essential process in wall construction, if there are problems with the construction effect of the putty layer, the overall effect of the exterior decoration surface layer will be greatly reduced. What are the problems that may arise during construction in such an environment? What should we do to prevent the environment from affecting the workability of Jinan putty powder?

干太快

Working too fast

膩子粉料在桶里調(diào)配時干的很快，難施工，批刮后失水快，膩子表面干燥太快而導(dǎo)致施工后不能正常壓。

When mixing putty powder in a bucket, it dries quickly and is difficult to apply. After scraping, it loses water quickly, and the surface of the putty dries too quickly, resulting in abnormal pressure 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。

【 Reason 】 The temperature in the construction environment is too high, the humidity is too low, the ventilation is too strong, and the direct sunlight accelerates the reaction of the composite materials in the putty.

【解決方法】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 during high temperature and direct sunlight periods, and control the ventilation intensity of the construction site. When the base surface becomes too dry or absorbs water quickly, it is recommended to brush the interface agent or wet the base surface in advance (but without clear water) before construction.

批刮翻卷、卷皮

Batch scraping, flipping, and peeling

膩子在批刮、收壓時出現(xiàn)翹起或呈鱗片現(xiàn)象。

The putty appears to be warped or scaly during batch scraping and pressing.

【原因】基面太干燥或施工現(xiàn)場溫度太高。

【 Reason 】 The base surface is too dry or the construction site temperature is too high.

【解決方法】基層太干燥時應(yīng)保濕施工，避開中午這種高溫時段施工。而針對批刮已翻皮的膩子應(yīng)該鏟除膩子，涂刷封閉材料后再重新批刮。

【 Solution 】 When the base layer is too dry, it should be moisturized during construction, avoiding high temperature periods such as noon. For the putty that has been peeled off in batches, the putty should be removed, and the sealing material should be applied before re scraping.

起泡

Bubbling

膩子批刮時產(chǎn)生氣泡或者批刮過后表面起泡。

Bubbles are generated during the batch scraping of putty or the surface blisters after the batch scraping.

【原因】夏季氣溫高，基層太干燥施工或者膩子外干內(nèi)未干，從而產(chǎn)生氣泡。

【 Reason 】 In summer, the temperature is high, and the base layer is too dry for construction or the putty is not dry outside and inside, resulting in the formation of bubbles.

【解決方法】可以潤濕基層后批刮，應(yīng)保證道膩子干透后再批刮面層膩子，調(diào)配膩子時應(yīng)按要求充分?jǐn)嚢瑁谶m宜溫度范圍施工。如若批刮時膩子有氣泡可在表干時反復(fù)收壓，消除氣泡。

【 Solution 】 The base layer can be moistened and then scraped in batches. It should be ensured that the first layer of putty is dry before scraping the surface layer of putty. When mixing the putty, it should be thoroughly stirred as required and constructed within the appropriate temperature range. If there are bubbles in the putty during batch scraping, it can be repeatedly compressed while the surface is dry to eliminate the bubbles.

掉粉、脫層

Powder shedding 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 a phenomenon of powder falling when touched by hand, and in severe cases, there may even be peeling between the front and rear layers of putty or between the putty and the substrate.

【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 is applied at high temperatures and dryness, and the moisture evaporates quickly. There is not enough moisture to cure, so it is easy to remove powder. The bottom layer of putty is loose and severely powdery, while the surface layer of putty is too hard and dries too quickly, which can cause delamination. In addition, after the external wall putty is washed away by rainwater, the adhesive is lost, and it is also easy to delaminate after re approval.

【解決方法】高溫、干燥強風(fēng)天氣施工，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 】 For construction in high temperature, dry and strong wind weather, it is recommended to wet the base surface without open water before applying putty. During construction, it is necessary to compact and control the drying time appropriately. Analyze the specific situation when dealing with it:

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. After applying sealing primer to the waterproof putty of the inner wall, the strength will increase and generally does not require additional treatment.

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 should strictly follow the moisturizing construction to avoid direct sunlight. After the surface layer of putty is dry, it should be timely and moderately polished and thoroughly watered for at least 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 the polished putty should be thinly coated with another layer of putty, and the polishing treatment should be carried out in a timely manner.
