How to avoid light gypsum hollowing? As a new type of wall plastering material, light plastering gypsum summarizes its causes and prevention methods from the aspects of wall pouring, whole wall and local hollowing. Let's follow the plaster manufacturer to learn about it! 1、 The main reasons for the hollowing of light plastering gypsum are as follows:

1、墙体未进行界面处理，墙面有灰尘、油渍等杂物，影响轻质抹灰石膏的粘结，导致空鼓。因此，轻质抹灰石膏施工前，需要先对墙面进行界面处理

1. The wall is not subject to interface treatment, and there are dust, oil stains and other sundries on the wall, which affect the bonding of light plastering gypsum and lead to hollowing. Therefore, before the construction of light plastering gypsum, the interface of the wall needs to be treated first

2、轻质抹灰石膏粘结性差，施工后出现空鼓现象。因此，在选购轻质抹灰石膏时，一定要选用合格的材料

2. The light plastering gypsum has poor adhesion and hollowing after construction. Therefore, when purchasing light plastering gypsum, we must select qualified materials

3、轻质抹灰石膏与水性界面剂不匹配，造成空鼓。在这种情况下，我们需要购买与轻质石膏相同的界面剂材料。

3. The light plastering gypsum does not match with the water-based interface agent, resulting in hollowing. In this case, we need to buy the same interfacial agent material as light gypsum.

二、轻抹灰石膏墙体空鼓的主要原因有：

2、 The main reasons for hollowing of light plastered gypsum wall are:

1、抹灰石膏附着力差，自身产品质量存在问题

1. The adhesion of plastering gypsum is poor, and there are problems in its own product quality

2、抹灰凝结时间过长，失去粘性，自然风干，造成空鼓。这两种情况都是由于轻质抹灰石膏本身的质量问题造成的，因此预防的方法是选用合格的轻质抹灰石膏材料。

2. The plastering setting time is too long, loses its viscosity, and is dried naturally, resulting in hollowing. Both cases are caused by the quality problems of light plastering gypsum itself. Therefore, the prevention method is to select qualified light plastering gypsum materials.

3、辅助保温，营造更舒服的生活环境；轻质抹灰石膏是一种阻燃材料。在火灾情况下，许多结晶水在热效应下从水合石膏的硬石膏基质中释放出来，产生蒸汽，从而防止火灾扩散。此外，它在整个干燥过程中消化和吸收大量热量，从而提高防火性能。

3. Auxiliary thermal insulation to create a more comfortable living environment; Light plastering gypsum is a kind of flame retardant material. In case of fire, many crystalline water is released from the anhydrite matrix of hydrated gypsum under thermal effect to produce steam, so as to prevent the spread of fire. In addition, it digests and absorbs a large amount of heat during the whole drying process, so as to improve the fire resistance.

用轻质石膏代替水泥砂浆，不仅具有水泥的强度，而且比水泥更健康耐用，是一种新型、环保、经济的推广。具有附着力大、不易粉碎、不开裂、不空鼓、不掉粉等优点。使用方便，节约成本。抹灰石膏是建筑石膏的结合剂。

Using light gypsum instead of cement mortar not only has the strength of cement, but also is healthier and more durable than cement. It is a new, environmental protection and economic promotion. It has the advantages of high adhesion, not easy to crush, not crack, not empty drum, not falling powder and so on. Easy to use and cost saving. Plastering gypsum is the binder of building gypsum.
