影响腻子粉性能的因素有哪些?

来源: 日期:2021-10-09 发布人:juyehe

新房装修的时候,都会使用到内外墙腻子粉,这样刮出来的墙面不仅平整,而且还很白。但是有时候出来的效果会不大好,这是什么原因呢?今天我们就一起了解一下济南腻子粉优良性能的因素是什么:

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、水泥对内外墙腻子粉的性能的影响:在水的作用下,水泥通过反应形成交联网状结构,因而能赋予腻子高粘结强度。当水泥用量达15%后,再增加水泥用量,腻子粉的粘结强度增加较缓慢。同时,水泥用量过大,易引起腻子膜层甚至表面涂层起裂纹。因此水泥用量控制在10%~40%范围较好。
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、粉煤灰用量对内外墙腻子粉性能的影响:随着粉煤灰用量增加,腻子粘结强度逐渐降低;当粉煤灰用量达30%以上时,强度降低相对较快。另外,随着粉煤灰用量加大,腻子施工性能有所改善。综合考虑,粉煤灰用量可控制在20%~30%范围内。
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、乳胶粉对内外墙腻子粉性能的影响:随着乳胶粉用量的增加,腻子粘结强度逐步加大;乳胶粉用量在2.5%以下,腻子粘结强度随乳胶粉用量增加较明显;乳胶粉用量在2.5%以上,腻子粘结强度随乳胶粉用量增加的幅度较小。由于随着乳胶粉用量的增加,腻子的成本增大,并有导致施工性变差的可能,因而乳胶粉的用量在2.5%~3.5%范围内较佳。另外,随着乳胶粉用量增加,腻子膜层干擦洗质量损失逐渐减少,当乳胶粉用量达2.5%以上时,腻子膜层质量损失趋于稳定,且质量损失很小。这主要是由于当乳胶粉达到此用量时,乳胶粉分散成胶液后能很好地将颜填料与基材粘结起来。
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.
大家在使用时注意好这3点就可以了。内外墙腻子粉环保无污染,具有非常好的耐水性能,非常适合应用于内墙混凝土面、水泥砂浆面、纸筋灰、石膏板等的基层处理,主要被应用于各种装修的基层处理,尤其是厨房、地下室、卫生间、浴室等的顶棚墙面,在潮湿的墙面上也可以进行施工。
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.
