Because of the stress deformation of the wall structure, cracks often appear after the completion of the external wall decoration. Some people think that cement-based putty powder for exterior wall is easy to crack. As long as the product has high elasticity, the crack problem can be solved. The specific situation of the crack is as follows:

　　了解我國(guó)建筑史(1)每個(gè)人都知道，建筑質(zhì)量問題是由于設(shè)計(jì)、施工、材料、木材、中國(guó)古建筑——北京故宮的城墻，使用彈性外墻膩?zhàn)臃郏F(xiàn)在560年過去了，沒有出現(xiàn)裂縫、開裂、脫落墻面革、滲水等問題。

　　To understand the history of architecture in China (1) everyone knows that the quality of architecture is due to the design, construction, materials, wood, the wall of Beijing Imperial Palace, the ancient Chinese architecture, and the use of elastic putty powder for external walls. Now 560 years have passed, there are no cracks, cracks, peeling off wall leather, water seepage and other problems.

　　而我們所謂的現(xiàn)代高科技產(chǎn)品，如“真石漆”、“乳膠漆”、“氟碳漆”、“釉面瓷磚”、“彈性膩?zhàn)?rdquo;、“GS防水材料”等，可以有幾年、幾十年、幾百年的使用壽命。采用彈性膩?zhàn)拥慕ㄖ诓牧虾凸に嚿暇蛇_(dá)到故宮博物院的水平。

　　And our so-called modern high-tech products, such as "real stone paint", "latex paint", "fluorocarbon paint", "glazed ceramic tile", "elastic putty", "GS waterproof material", can have several years, decades, hundreds of years of service life. The building with elastic putty can reach the level of the Palace Museum in material and technology.

　　現(xiàn)代建筑工程，包括基礎(chǔ)設(shè)施建設(shè)和裝修，由于施工高峰期，為節(jié)省資金和麻煩，質(zhì)量隱患較多，是多年以后，這些隱患依然存在，薄層膩?zhàn)樱绕涫菑椥阅佔(zhàn)硬荒軓母旧辖鉀Q這些問題。

　　Modern construction engineering, including infrastructure construction and decoration, has many quality hidden dangers due to the peak period of construction, in order to save money and trouble. After many years, these hidden dangers still exist. Thin layer putty, especially elastic putty, cannot fundamentally solve these problems.

　　彈性膩?zhàn)拥闹匾夹g(shù)指標(biāo)之一:動(dòng)態(tài)抗裂性(底部開裂)≥0.1mm， <0.3mm。

　　One of the important technical indexes of elastic putty: dynamic crack resistance (bottom crack) ≥ 0.1mm, < 0.3mm.

　　外墻膩?zhàn)臃?以滿足這個(gè)索引是很容易的,我們添加更多的好的彈性乳液可以做,問題是當(dāng)乳膠材料數(shù)量越大,影響越大基于水泥的后期強(qiáng)度和穩(wěn)定的膩?zhàn)?彈性乳膠維持時(shí)間是非常有限的。

　　External wall putty powder is easy to meet this index. We can add more good elastic emulsion to do it. The problem is that the larger the amount of latex material, the greater the impact. The strength of cement and the stable putty, the maintenance time of elastic latex is very limited.

　　墻體產(chǎn)生裂縫后,可以存在,及其裂紋大小,每,每一小時(shí),24小時(shí)不斷變化的,它會(huì)隨環(huán)境溫度的變化,濕度和變化,這種變化可以繼續(xù)建筑使用壽命結(jié)束的時(shí)候,要選擇質(zhì)量好、靈活性好外墻膩?zhàn)臃邸?/div>
