膩子層粉化嚴重是怎么造成的，應該如何處理?

來源：http://www.wavc.cn 日期：2021-03-02 發布人：

膩子干燥后掉粉，究其根源，可以歸結為粘結體系沒有發揮其作用，而為什么粘結體系，不論是無機粘結劑還是有機粘結劑失去作用，可以從以下幾方面考慮：

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 膩子粉本身粘結劑質量存在問題;

1. The binder quality of putty powder itself has problems;

2 粘結劑沒有發揮作用，膠粘劑的膠粘機理是含有膠粉的濕砂漿，隨著水份在基層吸收、水硬性材料反應消耗、面層向空氣揮發三方面減少，樹脂顆粒逐漸靠近，界面逐漸模糊，樹脂逐漸相互結合，成為連續的高分子連接體，這一過程主要發生在砂漿的氣孔及固體表面，所以形成了粘結作用。

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.

而如果我們由于批刮膩子層過薄或者批刮后強制通風或者加熱烘干，都會造成水份散失過快，粘結劑的樹脂顆粒不能很好的形成連接體，從而喪失了粘結作用。

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.

解決辦法：

terms of settlement:

輕度掉粉可以用濕毛巾將浮灰處理掉，然后用墻錮進行界面處理，再進行批刮就可以注意批刮厚度;膩子層如果粉化嚴重，則建議鏟除后用墻錮做界面處理再進行批刮。

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.
