腻子层粉化严重是怎么造成的,应该如何处理?

来源:https://www.jnfhjc.com 日期:2021-03-02 发布人:juyehe

腻子干燥后掉粉,究其根源,可以归结为粘结体系没有发挥其作用,而为什么粘结体系,不论是无机粘结剂还是有机粘结剂失去作用,可以从以下几方面考虑:
The reason of putty powder falling off after drying can be attributed to that the bonding system does not play its role. Why the bonding system, whether it is inorganic binder or organic binder, loses its role can be considered from the following aspects:
1 腻子粉本身粘结剂质量存在问题;
1. The binder quality of putty powder itself has problems;
2 粘结剂没有发挥作用,胶粘剂的胶粘机理是含有胶粉的湿砂浆,随着水份在基层吸收、水硬性材料反应消耗、面层向空气挥发三方面减少,树脂颗粒逐渐靠近,界面逐渐模糊,树脂逐渐相互融合,成为连续的高分子连接体,这一过程主要发生在砂浆的气孔及固体表面,所以形成了粘结作用。
two The adhesive does not play a role. The adhesive mechanism is the wet mortar containing rubber powder. With the decrease of water absorption in the base, reaction consumption of hydraulic materials and volatilization of the surface to the air, the resin particles gradually approach, the interface gradually blurs, and the resins gradually fuse with each other to form a continuous polymer connector. This process mainly occurs in the pores and solid surface of the mortar Therefore, a bonding effect is formed.
而如果我们由于批刮腻子层过薄或者批刮后强制通风或者加热烘干,都会造成水份散失过快,粘结剂的树脂颗粒不能很好的形成连接体,从而丧失了粘结作用。
If the putty layer is too thin or forced ventilation or heating and drying after scraping, the water will lose too fast, and the resin particles of the binder can not form a good connector, thus losing the bonding effect.
解决办法:
terms of settlement:
轻度掉粉可以用湿毛巾将浮灰处理掉,然后用墙锢进行界面处理,再进行批刮就可以注意批刮厚度;腻子层如果粉化严重,则建议铲除后用墙锢做界面处理再进行批刮。
For light dusting, wet towel can be used to remove the floating ash, and then wall block can be used for interface treatment, and then batch scraping can be used to pay attention to the thickness of batch scraping; if the putty layer is seriously powdered, it is recommended to use wall block for interface treatment and then batch scraping after removal.
