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(wèn)題一：干得快

Problem 1: fast work

膩?zhàn)臃哿显谕袄镎{(diào)配時(shí)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(guò)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(qiáng)及陽(yáng)光直曬，膩?zhàn)又械膹?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(shí)段、陽(yáng)光直曬時(shí)段施工，控制施工場(chǎng)地通風(fēng)強(qiáng)度。當(dāng)基面出現(xiàn)太過(guò)干燥、 吸水快的情況時(shí)建議刷涂界面劑或者預(yù)先濕潤(rùn)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(wèn)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?zhàn)又g或膩?zhàn)优c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?zhàn)釉诟邷馗稍飼r(shí)施工，水分揮發(fā)快，沒(méi)有足夠水分進(jìn)行固化，因而容易脫粉。而底層膩?zhàn)邮杷煞刍瘒?yán)重，面層膩?zhàn)犹?，干燥太快?huì)造成脫層。另外,外墻膩?zhàn)颖挥晁疀_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(qiáng)風(fēng)天氣施工，更好將基面潤(rùn)濕無(wú)明水后再進(jìn)行膩?zhàn)邮┕?。施工時(shí)要收壓密實(shí)，適度掌握干燥時(shí)間。處理起來(lái)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?zhàn)油窟^(guò)封閉底漆后，強(qiáng)度會(huì)增加，一般無(wú)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?zhàn)討?yīng)嚴(yán)格執(zhí)行保濕施工，避免陽(yáng)光直射施工，面層膩?zhàn)颖砀珊蠹皶r(shí)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?zhàn)颖砻鎽?yīng)再薄批膩?zhàn)右坏?，并及時(shí)進(jìn)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(wèn)題三：開裂

Problem 3: cracking

膩?zhàn)訉赢a(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(shí)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：?jiǎn)伪榕翁?，干燥太快，表干里不干，?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?zhàn)优翁竦母闪选?/div>
