界面處理層強度不夠，造成抹面砂漿層空鼓、剝離。在基層表面較光滑且抹面砂漿不易粘結的情況下，為保證濟南抹面砂漿與基體之間的粘結牢固，需對基層進行拉毛，這種材料叫做界面處理層。

The strength of the interface treatment layer is insufficient, resulting in hollowing and peeling of the plastering mortar layer. In the case where the surface of the base layer is relatively smooth and the plastering mortar is not easy to bond, in order to ensure the strong bonding between the Jinan plastering mortar and the substrate, it is necessary to roughen the base layer. This material is called an interface treatment layer.

灰漿固化后，抹面砂漿在后期不會發生水化和硬化情況，這一過程伴隨著砂漿的收縮。抹面砂漿層后期收縮在抹灰基體界面處理層形成了拉應力，抹灰層厚度約為厚，抹灰層的拉應力越大；抹灰層砂漿強度越高，對界面處理層拉應力越大；抹灰層砂層越細，抹灰層的拉應力越大。

After the mortar solidifies, the plastering mortar will not undergo hydration and hardening in the later stage, which is accompanied by the shrinkage of the mortar. The later shrinkage of the plastering mortar layer forms tensile stress in the interface treatment layer of the plastering substrate. The thickness of the plastering layer is about thick, and the greater the tensile stress of the plastering layer; The higher the strength of the plaster layer mortar, the greater the tensile stress on the interface treatment layer; The finer the sand layer of the plaster layer, the greater the tensile stress of the plaster layer.

后期收縮可能導致界面處理層與基體表面的粘結強度不夠，砂漿的抹灰層與基體表面的粘結強度不夠大，而抹灰層與基體之間的空鼓、剝落，則抹灰層與基體之間出現空鼓、剝離。出現這樣的情況，往往前期不會出現問題，一般半個月后，隨著時間的增長，抹灰層空鼓越來越嚴重。

Late shrinkage may lead to insufficient bonding strength between the interface treatment layer and the substrate surface, insufficient bonding strength between the mortar's plastering layer and the substrate surface, and hollowing and peeling between the plastering layer and the substrate, resulting in hollowing and peeling between the plastering layer and the substrate. When such a situation occurs, there is often no problem in the early stage. Generally, half a month later, as time goes on, the hollowing of the plaster layer becomes more and more serious.

要解決這一問題，首先要提高界面處理層與基體之間的結合強度和本身強度，保證與基體粘結牢固；二是砂漿抹灰一次抹灰厚度不能過厚，禁止一次抹成，每層抹灰應保持適當時間間隔；抹灰厚度超過20mm，要采取多次抹灰工藝。更多相關事項就來我們網站http://www.sjzmx.cn咨詢吧！

To solve this problem, first of all, it is necessary to improve the bonding strength and inherent strength between the interface treatment layer and the substrate, ensuring a solid bond with the substrate; Secondly, the thickness of mortar plastering should not be too thick at one time, and it is prohibited to apply it in one time. Each layer of plastering should be maintained at appropriate intervals; If the plastering thickness exceeds 20mm, multiple plastering processes should be adopted.
