When the new house is decorated, the putty powder on the inner and outer walls will be used. In this way, the scraped wall surface is not only flat, but also very white. But sometimes the effect is not good. What's the reason? Today, let's learn about the factors affecting the excellent performance of Jinan putty powder:

1、水泥對(duì)內(nèi)外墻膩?zhàn)臃鄣男阅艿挠绊懀涸谒淖饔孟拢嗤ㄟ^(guò)反應(yīng)形成交聯(lián)網(wǎng)狀結(jié)構(gòu)，因而能賦予膩?zhàn)痈哒辰Y(jié)強(qiáng)度。當(dāng)水泥用量達(dá)15%后，再增加水泥用量，膩?zhàn)臃鄣恼辰Y(jié)強(qiáng)度增加較緩慢。同時(shí)，水泥用量過(guò)大，易引起膩?zhàn)幽由踔帘砻嫱繉悠鹆鸭y。因此水泥用量控制在10%～40%范圍較好。

1. Effect of cement on the performance of putty powder for internal and external walls: under the action of water, the cement forms a cross-linked network structure through reaction, which can give the putty high bonding strength. When the amount of cement reaches 15%, and then increase the amount of cement, the bond strength of putty powder increases slowly. At the same time, excessive amount of cement is easy to cause cracks in putty film and even surface coating. Therefore, it is better to control the cement dosage in the range of 10% ~ 40%.

2、粉煤灰用量對(duì)內(nèi)外墻膩?zhàn)臃坌阅艿挠绊懀弘S著粉煤灰用量增加，膩?zhàn)诱辰Y(jié)強(qiáng)度逐漸降低；當(dāng)粉煤灰用量達(dá)30%以上時(shí)，強(qiáng)度降低相對(duì)較快。另外，隨著粉煤灰用量加大，膩?zhàn)邮┕ば阅苡兴纳啤＞C合考慮，粉煤灰用量可控制在20%～30%范圍內(nèi)。

2. Effect of fly ash content on the performance of putty for inner and outer walls: with the increase of fly ash content, the bond strength of putty decreases gradually; When the amount of fly ash is more than 30%, the strength decreases relatively quickly. In addition, with the increase of the amount of fly ash, the construction performance of putty is improved. Considering comprehensively, the amount of fly ash can be controlled in the range of 20% ~ 30%.

3、乳膠粉對(duì)內(nèi)外墻膩?zhàn)臃坌阅艿挠绊懀弘S著乳膠粉用量的增加，膩?zhàn)诱辰Y(jié)強(qiáng)度逐步加大；乳膠粉用量在2.5%以下，膩?zhàn)诱辰Y(jié)強(qiáng)度隨乳膠粉用量增加較明顯；乳膠粉用量在2.5%以上，膩?zhàn)诱辰Y(jié)強(qiáng)度隨乳膠粉用量增加的幅度較小。由于隨著乳膠粉用量的增加，膩?zhàn)拥某杀驹龃螅⒂袑?dǎo)致施工性變差的可能，因而乳膠粉的用量在2.5%～3.5%范圍內(nèi)較佳。另外，隨著乳膠粉用量增加，膩?zhàn)幽痈刹料促|(zhì)量損失逐漸減少，當(dāng)乳膠粉用量達(dá)2.5%以上時(shí)，膩?zhàn)幽淤|(zhì)量損失趨于穩(wěn)定，且質(zhì)量損失很小。這主要是由于當(dāng)乳膠粉達(dá)到此用量時(shí)，乳膠粉分散成膠液后能很好地將顏填料與基材粘結(jié)起來(lái)。

3. Influence of emulsion powder on the properties of putty powder for inner and outer walls: with the increase of the amount of emulsion powder, the bond strength of putty gradually increases; When the amount of latex powder is less than 2.5%, the bond strength of putty increases obviously with the increase of the amount of latex powder; When the amount of latex powder is more than 2.5%, the bond strength of putty increases slightly with the increase of the amount of latex powder. As the cost of putty increases with the increase of the amount of latex powder, and the workability may become worse, the amount of latex powder is better in the range of 2.5% ~ 3.5%. In addition, with the increase of the amount of emulsion powder, the dry scrubbing quality loss of putty film gradually decreases. When the amount of emulsion powder reaches more than 2.5%, the quality loss of putty film tends to be stable and the quality loss is very small. This is mainly because when the amount of latex powder reaches this amount, the latex powder can well bond the pigments and fillers with the substrate after dispersing into glue.

大家在使用時(shí)注意好這3點(diǎn)就可以了。內(nèi)外墻膩?zhàn)臃郗h(huán)保無(wú)污染，具有非常好的耐水性能，非常適合應(yīng)用于內(nèi)墻混凝土面、水泥砂漿面、紙筋灰、石膏板等的基層處理，主要被應(yīng)用于各種裝修的基層處理，尤其是廚房、地下室、衛(wèi)生間、浴室等的頂棚墻面，在潮濕的墻面上也可以進(jìn)行施工。

Just pay attention to these three points when using. Internal and external wall putty powder is environment-friendly, pollution-free and has very good water resistance. It is very suitable for the base treatment of internal wall concrete surface, cement mortar surface, paper reinforcement ash and gypsum board. It is mainly used for the base treatment of various decoration, especially the ceiling wall of kitchen, basement, sanitary room and bathroom. It can also be constructed on the wet wall.
