The coating is too thick to crack. Generally, the thickness of putty powder is 1-2 mm, not more than 3 mm. Some interior and exterior walls are not smooth, up to 3-5 cm, if all the putty powder leveling will certainly crack. Mortar leveling should be adopted. The greater the error, the thicker the mortar is required. Masonry mortar should be used to leveling the base, and putty can be filled with flexible agent.

　　內(nèi)墻膩子粉無機粘結(jié)劑的灰鈣粉和水泥的內(nèi)容太多,太多的強度,一般的裂紋內(nèi)墻膩子粉現(xiàn)象,如果灰鈣粉和水泥含量超過50%,強度太大,面對硬脆,容易產(chǎn)生裂紋,在過去,在中國大部分地區(qū)用膠水(107年不是107膠水,膠水對環(huán)境問題停止使用),加上舊粉或外墻用膠水和白水泥，很容易脫落粉末和開裂。

　　Inside wall putty powder inorganic binder of lime-calcium powder and cement content is too much, too much strength, the general phenomenon of cracked inner wall putty powder, if the content of lime-calcium powder and cement is more than 50%, strength is too large, facing brittle, easy to crack, in the past, in most parts of China with glue (107 is not 107 glue, glue ceases to use for environmental problems), plus old powder or external wall glue and white cement. It is easy to peel off powder and crack.

　　隨著外界冷熱溫度的變化，裂紋逐漸出現(xiàn)，裂紋沿著空鼓的方向發(fā)展，并沒有看到裂紋。如果你打開裂縫，你會看到膩子和墻的底部是兩層，中間一層是灰塵。解決這種墻的底部,看到墻重要的是,如果脫下粉紅色的嚴(yán)重的必須清理干凈,用水沖洗后但刮涂膩子,如果不是太嚴(yán)重,之后希望表層能夠使用膠輥刷,就可以完整的膩子。

　　With the change of external temperature, cracks gradually appear, and cracks develop along the direction of empty drum, and no cracks are observed. If you open the crack, you will see that the putty and the bottom of the wall are two layers, and the middle layer is dust. To solve the bottom of this kind of wall, the most important thing is to see the wall. If you take off the serious pink, you must clean it. After washing with water, but scraping putty, if it is not too serious, then you hope that the surface can use rubber roller brush, you can complete putty.

　　膩子一般由基材、填料、水和添加劑組成。

　　Putties generally consist of substrates, fillers, water and additives.

　　基材，又稱粘結(jié)劑，是膩子關(guān)鍵的組成部分，主要在粘結(jié)中起各種作用。膩子常用的粘結(jié)劑是水泥和有機聚合物，它們分為乳液和乳膠粉。水泥是一種良好的粘結(jié)劑，經(jīng)久耐用，性價比高，但抗拉強度和抗裂性較差。有機聚合物可以對膩子進行改性和增韌，從而提高膩子的性能。

　　Substrate, also known as binder, is the most critical component of putty, mainly plays a variety of roles in bonding. Putty most commonly used binder is cement and organic polymer, they are divided into emulsion and latex powder. Cement is a good binder, durable, cost-effective, but poor tensile strength and crack resistance. Organic polymer can modify and toughen putty, so as to improve the performance of putty.

　　填料主要用于碳酸鈣、滑石粉、石英砂等的充填。應(yīng)注意包裝細度的搭配。

　　The filler is mainly used for filling calcium carbonate, talc powder, quartz sand, etc. Pay attention to the matching of packing fineness.

　　輔助增稠劑、保水劑等。增稠劑和保水劑具有保水、改善貯存性能和施工性能的作用，一般采用纖維素。防凍劑主要用于提高膩子在低溫下的貯存穩(wěn)定性。

　　Auxiliary thickener, water retaining agent, etc. Thickening agent and water retaining agent have the functions of water retaining, improving storage performance and construction performance, and cellulose is generally used. Antifreeze agent is mainly used to improve the storage stability of putty at low temperature.

　　一些還添加了纖維來抵抗開裂。

　　Some also add fibers to resist cracking.
